Automatic reciprocating fluid valve

Abstract

The invention provides an automatic reciprocating fluid valve, and relates to the field of valves. The automatic reciprocating fluid valve comprises a reciprocating valve element, a reversing valve element, a reciprocating valve body, a reversing valve body, a mechanical connecting rod and a piston; the reciprocating valve body and the reversing valve body are hollow cavities; the piston is located outside the reversing valve body and is arranged at one end of the mechanical connecting rod in a sleeving mode; the reversing valve element is located in the cavity of the reversing valve body and is arranged at the other end of the mechanical connecting rod in a sleeving mode; the reciprocating valve element is located in the cavity of the reciprocating valve body; and two fluid inlets and two fluid outlets are formed in the upper end of the reciprocating valve body. The automatic reciprocating fluid valve has the advantages that the self-power of fluid is used for achieving automatic reversing of the fluid in the reciprocating motion process of a fluid executing mechanism, an electromagnetic or manual valve does not need to be arranged at the power end, the reciprocating motion speed of the executing mechanism can be accelerated by installing the device on the executing mechanism, and therefore the working efficiency can be improved, and the fault rate can be reduced due to the fact that the electromagnetic valve is not adopted.

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
