    专利说明:

    The invention relates to reinforcement and can be used in nuclear power engineering.
    The known site of the connection of the cover with the valve body, comprising a pipe with an omental seal fixed in it and a lid with a neck, the pipe and the lid being provided with their connecting segments and gland screws. Such a construction is given in the description of the invention to the Copyright Certificate of Czechoslovakia No. 137442, cl. F 16 K 51/00, 1970.
    A disadvantage of the known lid-to-body connection node is that the lid does not have the possibility of axial movement relative to the valve body.
    This disadvantage is eliminated by the proposed device, which is a node connecting the lid to the valve body, comprising a nipple with a gland seal fixed therein and a lid with a throat, the nipple and the lid being provided with segments connecting them and gland screws. the covers are made with threaded holes, into which the stuffing screws are screwed, with the bottom part of the stuffing screws being installed with support on the upper surface of the body segment.
    In addition, the lower part of the gland screws is made in the form of a spike, and a recess with a razzenkovka is made on the upper surface of the branch pipe segment to fit the spike.
    The design of the joint assembly according to the present invention provides great efficiency, manifested in that while maintaining the simplicity of the structure and easy installation and disassembly, the gland is compressed and the lid is rotated relative to the valve body, and the axial movement of the lid in relation to him. This prevents the force required for a strong bayonet joint against excessive tightening of the gland which impedes the movement of the spindle, and also eliminates the loosening of the bayonet joint due to wear of the packing gland packing.
    FIG. Figure 1 shows the joint assembly, a vertical section along the axis in a turn, passing through the main joint; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a joint assembly, a vertical section along the axis in a turn, passing through an alternative joint; in fig. 4 shows a section BB in FIG. 3
    According to the present invention, the valve body 1 has a pipe 11 through which the spindle 2 passes. The latter in the lower part is sealed with a bellows 3, and in the upper part with a gland seal 4 with gland packing 5, which is pressed against the pressure cap 6 with gland screws 7. On the outer surface of the 111 pipe 11
    there are two segments 112 of the valve body 1, which on the upper surface 113 have a recess 114 with rezinkovka 115 to fit the lower part of the gland screw 7. From the bottom, on the segments 112 of the valve housing 1 there are special places - surfaces for contacting 116. At the centering diameter 117 of the socket 11 The valve body 1 is fitted with a cover 8, the lower part of which is the neck 81. In the lower part of the neck 81, on its inner surface 811 there are segments 82 of the cover 8 and the upper surface 821 of the abutment. In the upper part 812 there are threaded holes 83, designed in such a way that after the cover 8 is seated on the nozzle 11 they are on the same diameter,
    0 as well as notch 114 in body segments 1.12. In the threaded holes 83, the gland screws 7 are screwed on the lower turn 71, the lower part of which is a cylindrical spike 72, which rests on the rezzenkovka 115, made in the recess 114 of the housing segment 112 112. The gland screws 7 have in their middle part the holding surfaces 73 In the upper part there is the upper turn 74, on which the gland cover 6 is located and the nut 9 is screwed.
    In another embodiment (Fig. 3 and 4), on the upper surfaces 113 of the segments 112 of the housing 1, there are no notches 114 with a reamer 115, the stuffing screws 7 with their lower part of the whole lisch
     into the upper surface 113 of the segments 112 of the housing 1. To ensure a radial rotation on the outer contour 111 of the pipe 11, there are two special areas 118 on which the outer side walls 822 of the segments 82 are mounted on the assembly
    0 of the cover 8. When mounting, the cover 8 after fitting on the centering diameter 117 of the nozzle 11 is rotated in such a way that the segments 112 of the valve body and the segments 82 of the cover 8 are located one above the other.
     In the threaded holes 83 in the upper part 812 of the neck 81, the gland screws 7 are screwed with their lower turn 71 until the screws 7 with their lower part, i.e. the cylindrical spike 72, enter the reztenkovka 115 of the notch 114 on the upper surface 113 segment 112 body 1 valve. When pushed, the cover 8 rises until the upper abutment surface 821 of the segments 82 of the lid 8 and the lower abutment 5 of the surface 116 of the segments 112 of the housing 1 are mutually touching. Thereby a shtykovy connection will take place ensuring both radial rotation and axial rotation.
    movement. Then, a pressure cap 6 is inserted into the upper turn 74 of the gland screws 7, which is pressed while the nut 9 is tightened. When dismounted, the reverse reception is carried out. When replacing the stuffing box 5, it is sufficient to loosen the nuts 9-, while the strength of the bayonet connection of the housing 1 and the cover 8 is not broken. These methods of compounds are not the only solutions that follow from this invention. For example, the bottom
    Part of the gland screws 7 may be flat, spherical or tapered. In addition, the number of segments 112 of the housing 1 and the segments 82 of the cover 8 or the number of special pads 118 on the pipe 11 may be different depending on the size and type of valves.
    It is recognized as an invention according to the results of the examination carried out by the Office for the Invention of the Czechoslovak Socialist Republic.
