from cast iron or other metal alloy or from plastic; In case 1 there are horizontal nozzles 2 with longitudinal axis XX for entry and exit of the transported fluid, which are intended to be connected using, for example, flanges with a pipe (not shown), and a tube-like chamber 3 with a vertical axis YY.
The nozzles 2 have an internal cavity 4 of cylindrical shape with a circular cross section, and in a tube-like chamber 3 there is an internal field 5 with an axis Y-Y also a cylindrical, but slightly elliptical section. The cavity 4 is interrupted at the intersection with the continuation of the chamber 3 by the surface of the saddle 6 formed by the nozzles 2.
The saddle 6 is intended to interact after moving from the upper open position to the lower closed position of the locking member 7, driven by the threaded control rod 8, and the axis U-Y. The upper end of the blade 8 is rotatably mounted without moving in the top of the body 1 (not shown, and its lower end interacts with the nut (not shown) tightly embedded in the upper part of the locking member 7. The planes of the symmetry of the locking member 7 are vertical the Q plane, which includes the X-X and Y-Y axes, and the vertical P plane, which includes the Y-Y axis, but perpendicular to the X-X axis ...,
The locking member 7 can be made of any appropriate material, such as, for example, gray cast iron, cast iron with spheroidal 15

graphite, steel, copper alloy, plastic, in any suitable way (precision casting, stamping, machining, etc.) In this case, the locking member 7 is hollow, consists of two halves, completely covered with rubber sealing gasket 9 , and has the shape of a key, perpendicular to the axis XX and the size f corresponding to f the internal cavity 4 of the nozzles 2 and the shape of the saddle 6 so as to enter between the nozzles 2 and abut tightly against the saddle 6. In the upper part of the locking member 7, except for the casing 10, which is the nut stem 8 control There are two pairs of guide elements 1, parallel to the axis X-X and located on both sides of the vertical plane Q.
The guide elements 11 interact with two vertical guide elements 12, located in the vertical plane of symmetry P of the locking device inside the chamber 3, forming a protrusion relative to the internal cavity 5 of this chamber.
The invention includes two embodiments of the surface of the saddle 6 and the closure member 7.
The shape of the sealing rubber gasket 9 of the closure body 7 is similar to the sealing surface of the seat 6 and is made in the 35 Q plane, perpendicular to the longitudinal axis X-X of the nozzles 2, X-shaped and formed by two semi-surfaces 13, symmetrical with respect to the P plane, perpendicular longitudinal axis X-X nozzles 2.
Each semi-surface 13 of the sealing surface of the saddle 6 is profiled and contains

FIG. 5-12 is a variant of the implementation according to which each 13 seals of the saddle 6 are made up of the longitudinal Fpatubkov 2 longitudinal to the curvature upper half halfway above the longitudinal side have two similar planes, and led at the top is equal to the Below longitudinal axis X of the semi-surface curvilinear . This allows several structures.
In FIGS. 18-21, while the embodiment of the upt of the surface of the saddle 6 is performed, the surfaces 13 are crossed in the zone of intersection 13 which allows the closure body 7 to be operated with tolerances. .
FIG. 22 represent the Q plane of the surface surface of the saddle 6. L, N, M, and Kg, are sections: ve 0, lower N, M iK,, exact, transitional, and between themselves upper parts O, L, N, and C in order to reduce the longitudinal dimension (distance K, Kj) of the PU;

In this connection, the surface of the saddle in the π plane O is represented by
(in the first embodiment, the curvature of the curves K, O, L,
all upper sections of the sealing surface of the saddle 6 are smoothly interconnected, they correspond to sections 17, 18 and 19 of the sealing gasket 9 of the locking member 7,
Thus, the sealing surfaces of the seat 6 and the closure body 7 have two continuous semi-surfaces intersecting in the diametral zone of the axis X-X of the sockets 2.

The locking organ 7 of the drants consists of two strips 21 connected by pins 22, made of shells 21 and inlet slots 23 on a kex 21. There are also one another internally formed on the sheath by crushing them, creating on the locking gasket

FIG. 5-12, there is shown another embodiment of the device, according to which each half-surface 13 of the sealing surface of the seat 6 is made flat, passing Fpatrubka 2 to the curvilinear, i.e. the upper portions of the semisurfaces 13 lying above the longitudinal axis X-X have two converging straight linear planes, with the cusp at the apex equal to or greater than 20. Below the longitudinal axis X-X, the sealing semi-surfaces 13 remain curvilinear. Such an implementation allows a somewhat simpler design.
FIGS. 18-21 show one more embodiment of the sealing surface of the saddle 6, according to which, at the intersection of the two half-surfaces 13, the lip 20 is filled, which allows the saddle 6 and the closure body 7 to be provided with larger tolerances. .
FIG. Figure 22 shows the projection onto the plane Q of the line of the sealing surface of the saddle 6. Curves K, O, L, N, M and Kg, g 2 include the sections: upper K, O, K, 0, lower N, M IR, H w intermediate, transitional and interconnected upper parts and lower parts O, L, N and 0, L, Mg. In order to reduce the maximum longitudinal size of the saddle 6 (distance K, Kj) by displacement, two symmetric curves parallel to axis X-X are closer to each other in such a way that they intersect at the points L or b on the axis.
In this connection, the sluggish surface of the saddle, mounted on the plane O, is a common

The locking member 7 for the described variants consists of two thin shells 21 connected by conical pins 22 made on one of the shells 21 and entering in conical slots 23 on the other shell 21. There are also abutting internal projections 24 made on the shells 21 preventing their crushing when creating a sealing gasket 9 on the closure body 7, which
injected under pressure into the form in which the valve is 7..
In addition, on the inner surfaces of the shells 21 there are two pins 25 that prevent the shells 21 from being separated as a result of the shearing during the closure of the device in the event that any extraneous lreadmet gets under the closure body. The sealing gasket 9 has a variable thickness, forming a thickening 26 in the area of the sealing lip. The locking body 7 can be made monolithic.
The device works as follows.
When the control rod 8 is closed, the locking member 7 is pressed against the part of the seat 6 opposite to the direction of this pressure, and the sealing surface is the line K, L, M (Fig. 22).
If this tightness line is projected onto the diametrical plane passing through the axis XX and perpendicular to the axis YY, then according to the second embodiment of the invention, a half-half-shaded surface is obtained, represented in the lower part of FIG. 23, This is the surface on which a force must be applied to open the closure member 7 and overcome the pressure of the fluid it is experiencing. Resistance that needs to be overcome
S
to open the closure member 7, there is the product of multiplying the surmounted pressure by the area g of the projected surface (shaded in Fig. 23). Resistance at the same fluid pressure is greater, the larger the projected surface area, 0 When the area decreases, the sealing surfaces of the seat 6 and, consequently, the valve body 7 of the proposed geometry are reduced, the resistance that must be overcome for opening is reduced. valve body 7, i.e. you can use drive means of smaller power and size
In addition, the longitudinal dimension is reduced, i.e. the distance between the flanges of the pipes 2, measured parallel to the X-X axis, with the same pipe diameter and the same minimum angle between the X-X axis and the plane tangential to the sealing surface. tee saddles 6,
Due to the shape of the saddle 6 and the shape of the locking member 7, the latter is displaced to the saddle 6 or is removed. from it with minimal friction, since the surfaces that must come in contact to ensure tightness move relative to each other with almost no slip. From this it follows that the rubber sealing gasket 9 is subjected to minimal wear.
