Automatic reciprocating fluid valve

Abstract

The invention provides an automatic reciprocating fluid valve, which relates to the field of valves and includes a reciprocating valve core, a reversing valve core, a reciprocating valve body, a reversing valve body, a mechanical connecting rod and a piston, and the reciprocating valve body and the reversing valve body are both It is a hollow cavity; the piston is located outside the reversing valve body and sleeved on one end of the mechanical connecting rod, and the reversing valve core is located inside the reversing valve body cavity and is sleeved on the other end of the mechanical connecting rod; the reciprocating The valve core is located inside the cavity of the reciprocating valve body, and the upper end of the reciprocating valve body is provided with two fluid inlets and two fluid outlets; this device uses the power of the fluid itself to realize the automatic reversing of the fluid during the reciprocating movement of the fluid actuator. , there is no need to configure electromagnetic or manual valves at the power end. By installing this device on the actuator, the reciprocating speed of the actuator can be accelerated, and the work efficiency can be improved. Because the electromagnetic valve is not used, the failure rate can be reduced.

Description

technical field [0001] The invention relates to the field of valves, in particular to an automatic reciprocating fluid valve. Background technique [0002] Fluid valves are valves that control fluid flow by changing the cross section or length. A one-way throttle valve can be combined by connecting the throttle valve and the one-way valve in parallel. Throttle valve and one-way throttle valve are simple flow control valves. In the quantitative pump hydraulic system, the throttle valve and overflow valve can be combined to form three kinds of throttling speed regulation systems, that is, throttling and speed regulation of the oil inlet circuit. system, oil return throttling speed regulating system and bypass throttling speed regulating system. [0003] In the prior art, during the reciprocating motion of the fluid actuator, an electromagnetic or manual valve needs to be installed at the power end, and the failure rate of the electromagnetic valve is high. At the same time, ...

Problems solved by technology

[0003] In the prior art, during the reciprocating motion of the fluid actuator, an electromagnetic or manual valve needs to be installed at the power end, and the failure rate of the electromagnetic valve is high; at the same time, because a large amount of fluid needs to flow back into the pump, the problem of heat dissipation is difficult to solve
