The overlapped sequence valve is characterized in that one side of the valve body is provided with a pressure detection opening, a pressure meter is connected with the pressure detection opening, the other side of the valve body is provided with a spring, one side, near the valve core, of the spring is provided with a force sensor, the other side of the spring is provided with a regulating screw rod, the spring is arranged at one side of the valve body through an external valve cover, the bottom of the valve body is provided with an oil inlet, an axial hole is formed between the oil inlet and the pressure detection opening, and an oil outlet is formed in the top of the valve body. The overlapped sequence valve has the advantages that the structure is simple, the cost is low, the control deviation is small, and the pressure regulating precision is improved.
Description
Technical field
The present invention relates to a kind of overlapping sequence valve.
Background technique
The fundamental function of sequence valve is the sequentially-operating controlling multiple executive component, in order to make executive component accurately realize sequentially-operating, requires that the regulation precision of sequence valve is high, deviation is little.Traditional overlapping sequence valve adopts spring to carry out adjustment pressure, and in long using process, spring can produce deformation, easily causes control deviation large, reduces regulation precision.
Summary of the invention
For the problems referred to above, the invention provides a kind of overlapping sequence valve, structure is simple, cost is low, control deviation is little, improve regulation precision.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of overlapping sequence valve, comprise and there is certain thickness valve body, spool is provided with in valve body, it is characterized in that, described valve body side is provided with Pressure testing mouth, one pressure gauge is connected with Pressure testing mouth, the opposite side of valve body is provided with spring, spool side is provided with force snesor with described spring and opposite side is provided with adjusting screw rod, described spring is arranged on the side of valve body by outside valve gap, described body base is provided with a filler opening, is provided with axial bore between described filler opening and Pressure testing mouth, and described body top is provided with oil outlet.
Preferably, described force snesor is diaphragm type force snesor.
Preferably, described spring is helical spring.
Can pass through the both sides parameter of pressure gauge, force snesor Real-Time Monitoring overlapping sequence valve, further can learn control accuracy, the design can make that the structure of sequence valve is simple, cost is low, control deviation is little.
The invention has the beneficial effects as follows: a kind of overlapping sequence valve, structure is simple, cost is low, control deviation is little, improves regulation precision.
