SHOCK VALVE Russian patent published in 2022 - IPC F15B21/12 F24D3/02 

FIELD: hydrodynamics, hydraulics and mechanical engineering.

SUBSTANCE: invention relates to the field of hydrodynamics, hydraulics and mechanical engineering, where it can be used in devices for various purposes that use the effect of hydraulic shock, as well as to heat supply, where it can be used to create a pulsed movement of fluid in relation to the intensification of heat transfer in thermal power plants. The shock valve includes a hollow body with inlet and outlet openings for the expiration of the working medium, a shock valve rigidly fixed on the rod, a shaft, a spring, a centering plug and a guide sleeve. The structure additionally comprises lower and upper cylindrical bushings cut from below and from above perpendicularly into the housing, in the upper cylindrical bushing on the guide bushings there is a latch axis, which alternately engages with one of the teeth of the sprocket, at the ends of the guide bushings are pressed against the upper cylindrical bushing by end caps. In the lower cylindrical bushing on the guide bushings there is a shaft made integral with the sprocket and connected to the external drive through the guide bushing, the centering plug is pressed against the shaft through the ball. The spring rests at one end on the protrusion of the stem, and at the other end on an additional bushing, pressed by a nut, and between the bushing and the nut, a shock valve seat is clamped, and the shock valve is connected to the stem by means of a nut.

EFFECT: invention improves the reliability and efficiency of the device by reducing mechanical losses in the shock valve drive and expanding the control range of the stroke and opening angle of the shock valve.
