    Safety hose
    Safety hoses conforming to the above general concept are known, for example, from EP-A-0 567 115, DE-C-44 16 953 and DE-A-44 38 840. However, since the outer layer of the safety hose according to DE-C-44 16 953 is perforated in the case of the rigid support system (II) having greater chemical resistance than the rigid support system (I), the hose (body part) is defective. If present, material can penetrate and leak outside. This represents a significant risk to the user in some cases of hose failures that are not immediately repaired. In the case of such a hose, if corrosive, toxic or explosive material spills, this can result in damage to the device or personal injury.
    On the other hand, according to the current state of the art, it is very difficult to develop a safety system suitable for all kinds of substances due to the severe variety of materials. Thus, hoses have already been developed that can indicate damage before the hose reaches material leakage. Thus, the rigid support system I was provided with a conductive material (for display). If this rigid support system ruptures, the electrical conductors will also be defective and thus the failure of the conductors can be indicated (EP-A-0 567 115, DE-A 44 38 840). Of course, treatment with such a system is not applicable for all materials.
    In particular, the present invention relates to a safety hose made of an elastomeric material and / or a synthetic resin for conveying environmentally harmful substances (such as chemicals), and includes an inner layer (core), an outer layer (cover) and embedded rigid support. The rigid support further includes two rigid support systems, each of which is formed in a single layer or multiple layers, with at least one separating intermediate layer between the two rigid support systems, and a rigid support system close to the inner layer. It is called stiffness support system (I) below.-It has a small elongation (elongation), especially elongation <10% and high chemical resistance to the material to be transported, while a rigid support system close to the outer layer is Named System (II)-has a high extension rate, in particular> 10%.
    1 is a longitudinal sectional view of a safety hose in which two-zone systems A and B of a circularly extending bonding system III are disposed between the rigid support system II and the outer layer,
    FIG. 2 is a longitudinal sectional view of the safety hose in which the two-zone systems A and B of the circularly extending bonding system IV are arranged between the rigid support system II and the intermediate layer and with an additional layer,
    3 is a plan view of a circularly extending two-zone system A, B in which an axially extending passageway is arranged in zone B. FIG.
    In the background of this state of the art, it is now an object of the present invention to provide a safety hose free of material leakage until the replacement of the hose even when the main body becomes unsuitable for use.
    This object is achieved by a safety hose having the features of claims 1 or 2 according to the invention.
    In one embodiment there is a bonding system (hereinafter referred to as bonding system (III)) between the rigid support system (II) and the outer layer, the bonding system having a two-zone system (A, B extending in a circular, spiral or axial direction). ), Which is characterized by less adhesion (adhesive action) compared to one zone-hereinafter referred to as zone (A)-is called another zone-referred to as zone (B) below. In particular for III) the following various aspects can be used:
    -The bonding system (III) is integrally connected (ie materially bonded) to the outer layer (3), and the different bonding action in the two-zone system (A, B) is particularly direct (ie no additional layer) of the rigid support system ( II).
    However, for manufacturing reasons, the bonding system III forms a self-adhesive layer, and the different bonding action in the two-zone systems A and B is solely supported only on the side 4 on the side of the rigid support system II, in particular directly. Is applied to the system.
    According to another aspect, there is an adhesion system (hereinafter referred to as an adhesion system (IV)) between the rigid support system (II) and the intermediate layer (2), which also has a circular, spiral or axially extending two-zone system. (A, B) is provided, and the system already has the above-described difference in adhesion force (adhesion action), and this adhesion system (IV) uses the following aspects.
    -The bonding system IV is integrally connected with the intermediate layer 2, and the different bonding action in the two-zone systems A and B is directly or preferably bonded to the rigid support system II and preferably rigid. It is applied to an additional layer between supporting systems II. The additional layer then advantageously has a smaller thickness than the original intermediate layer.
    For manufacturing reasons, the bonding system IV forms a self-adhesive layer, and the different bonding action in the two-zone systems A and B is entirely on the side of the rigid support system, in fact directly on the rigid support system II. Or to an additional layer as described above.
    Regarding the bonding systems III and IV having the two-zone systems A and B according to the present invention, the following aspects are established for the purpose, irrespective of the above alternatives or variations:
    Adhesion is virtually constant within each zone (A, B) itself.
    The bonding systems III, IV extend substantially over the entire hose length.
    The zone A with a small adhesion has an adhesion value <1 N / mm, in particular ≦ 0.5 N / mm, while the zone B with a large adhesion has an adhesion value> 1 N / mm, in particular ≧ 2 N / has mm.
    Zone B with large adhesion has a width b smaller than width a of zone A with small adhesion, in particular the expression of the following variable width is established.
    b = (10 to 30%) of a
    In the case of two-zone systems (A, B) extending in a circular or helical manner, the width (a) of the zone (A) with a small adhesion has between one and three times the outer diameter of the hose.
    In the case of an axially extending two-zone system (A, B) there are at least three zones (A) divided along the hose.
    At least one axially extending passageway, in particular in the case of a circularly extending intermediate system (A, B), has a large adhesive force (B) and the width (c) of the passageway is at least 5 mm (based on a plan view) )to be.
    The intermediate layer 2 and the further layer 6 according to claim 5 are composed of a thermoplastic elastomer.
    In the region between the two rigid support systems (I, II), a hardening spiral member made of synthetic resin or metal material is arranged, and the spiral member is characterized by high chemical resistance to the material to be conveyed. It is further advantageously advantageous to extend directly adjacent to one of the two rigid support systems I and II.
    It is advantageous to have an electrically conductive system in the rigid support system (I) and / or (II), where the following parameters are established:
    -For break elongation> 10%, the rigid support system (II) includes an electrically conductive system with a break elongation of <10%.
    -For break elongation <10%, the rigid support system (I) includes an electrically conductive system with a fracture elongation not greater than the rigid support system (I).
    The conduction system is particularly advantageous if it is connected with a warning system arranged in the region of the hose end.
    Now, the present invention will be described in detail with reference to the amblyopia drawings.
    1 and 2 collectively show two hose structures showing the following basic configuration:
    1 inner layer (core)
    2 mezzanine
    3 outer layer (cover)
    Ⅰ Stiffness support system with small extension rate and high chemical resistance
    Ⅱ rigid support system with high extension rate
    According to FIG. 1, there is now an adhesion system III with a two-zone system A, B extending in a circular (circumferential) direction between the rigid support system II and the outer layer 3, wherein zone A is a zone. It is characterized by a smaller adhesion (adhesive force) than in (B). At this time, the bonding system III forms a self-adhesive layer, in which the different bonding forces in the two-zone systems A and B act solely on the side 4, close to the rigid supporting system II, in fact directly on the rigid supporting system. The side surface 4 'toward the outer layer 3 of the bonding system III is maintained in a usual constant bonding state.
    According to FIG. 2, the safety hose is provided with an adhesive system (IV) having a two-zone system (A, B) between the rigid support system (II) and the intermediate layer (2) and also extending in a circular manner. It is a feature that adhesive force is small compared with (B). In this example, an additional layer 6 having a thickness smaller than the original intermediate layer 2 is arranged between the bonding system IV and the rigid support system II. Also here the bonding system (IV) consists of self-adhesive layers, in which the different bonding forces in the two-zone systems (A, B) are entirely on the side (5) on the side of the rigid support system (II), in fact on the additional layer (6). Being applied. The side surface 5 'of the intermediate layer 2 side of the bonding system IV is in a regular constant bonding state.
    FIG. 3 now shows a circular two-zone system (A, B) having a width (a) for zone (A) and a width (b) for zone (B), with the width (c) within zone (B). There is an axially extending passage 7 with).
    These embodiments show that even in the case where the main body, i.e., the inner layer 1, the rigid support layer I and the intermediate layer 2 are defective, the emergency performance part can be formed without material release. Thus, for example, in the case of the safety hose according to FIG. 1, the outer layer 3 forms a vesicle (small sac) by softening the material at a part of the zone A, so that the vesicles can be stored therein. In the case where two-zone systems A and B are arranged helically or axially, the material can be moved helically or axially in the hose direction.
    In case the two-zone system A, B extends in a circular manner, according to FIG. 3 the zone B has at least one axially arranged passageway 7 and the width c of the passageway is at least 5 mm. There is an advantage when.
