FIELD: machine engineering.
SUBSTANCE: device comprises a valve body (112), a valve seat (120) located between the inlet and outlet, a return rod (136) moving between the retracted and the reduced position. The valve plate support (160) comprises a threaded rod and is connected to a return rod (136). The valve plate (122) interacts with a support rod and is made with the ability to move in response to the movement of the valve plate support (160) between the open position and the second closed position in which the valve plate (122) is adjacent to the valve seat (120). A threaded nut (206, 208) attached to the threaded part of the rod of the valve plate support (160), also, a locking spring (210), protected by a threaded nut (206, 208), is disposed on the rod of the valve plate support (160). The locking spring (210) applies a biasing force to the valve plate (122). Versions of the device and method of stopping the valve plate are described.
EFFECT: increase the reliability.
