    This invention relates to pipe fittings.
    The purpose of the invention is to simplify the design of valves.
    Figure 1 shows shut-off valves, vertical section; figure 2 - the head part of the bracket shut-off valves; on fig.Z - |) cut A-A on figure 2.
    The shut-off valve has a housing 1 with a lid 2, through which the spindle 4 is sealed and sealed with an epiploon 3. At the lower end of the spindle 4 a locking element 5 is fastened, which is adjacent in the closed position to the sealing surfaces 6 of the housing 1. The brace 7 is mounted on the housing 1 with the head part 8 in which a threaded sleeve 9 with an external thread in its lower part is installed for rotation and axial movement. The threaded sleeve 9 is connected at the upper end through a parallel wrench 10 to an electric servo (not shown) mounted on the head part 8 directly or via a counter drive. A thrust nut 12 with a right-handed thread is screwed onto the protruding part of the threaded sleeve 9 through the bottom wall 11 of the head part 8. A bolt 13 is inserted into the clip of the bracket 7. On the upper end side of the bottom wall 11, there is mounted a spring element 14 consisting of three cup springs, on which the thrust bearing 15 of the threaded sleeve 9 is supported. The spindle 4 is provided with a sealing shoulder 16. The bolt 13 is connected to an arrow 17, mounted on the bracket 7 for rotation.
    The locking device operates as follows.
    The spindle 4 connected through the left trapezoidal thread with the threaded sleeve 9 moves with the right rotation of the threaded sleeve 9, i.e. in the direction of the closing valve position. A threaded nut 12 (figure 2) is screwed onto the part of the threaded sleeve 9 protruding through the bottom wall 11 of the head part 8 (FIG. 2). The right precise thread is used for this purpose, so that it is secured against rotation by means of the bolt 13 inserted into the shearstock of the bracket 7 down passes a small way up compared to moving the spindle.
    Dp significant reduction in the path that the thrust nut 12 passes between both end positions, the external thread of the threaded sleeve 9 and the internal thread screwed on
    her thrust nuts 12 are made with a smaller pitch than the thread of the spindle 4,
    Under normal conditions, i.e. with the servo actuator operating without interference, the thrust nut 12 in the closed position of the shut-off valves remains slightly below wall 11, i.e. without contact with her. Only in the event of a malfunction, if after the completion of the process of closing the servo drive does not turn off, the thrust nut 12 comes into contact with the lower end side of the bottom wall 11 (position o, Fig.2).
    On the upper end side of the bottom wall 11 of the head part 8 of the bracket 7 there is installed a spring element 14 consisting of three cup springs, on which the thrust bearing 15 of the threaded sleeve 9 is supported. In the event that the servo does not turn off after the end of the process, further work the servo drive threaded bushing 9 moves down the thread now tightly fitting the thrust nut 12. The force of the tensioned spring element 14 counteracts this movement. Depending on the force of the spring element 14 and the existing working path of the spring, the servo is braked in a predetermined manner and is stopped.
    The spring element 14 reduces the stiffness of the stop valve acting on the stop in both directions of movement of the spindle 4. Since the forces transmitted during the conversion of kinematic energy into spring energy are mostly perceived by the threaded sleeve 9 and transferred further to the spring, the spindle load remains relatively low.
    A similar process takes place if the servo does not stop working after opening the valves.
    As a stop to determine the maximum upward movement, there is an aperture flange 16 installed on the pin 4, if the bead is adjacent to the cover 2, then the servo that continues to operate causes the threaded sleeve 9 to move downwards. In this case, the spring element 14 is tensioned, the servo is braked and stops.

    13 moves from position "to position b
    Since this movement is inversely proportional to the movement of spindle 4, it can be used for the indicator tool (FIG. 3). For this purpose, the bolt 13 is connected to an arrow 17 installed rotatably on the bracket 7, moving in the opposite direction to the movement of the bolt 13, thereby providing an optically correct indication of the locking element.
