Interpretation of the characteristics of the hydraulic system relief valve 2013-5-25

In the introduction we said before the hydraulic system relief valve, I believe we still have the impression, and today we have to say that this is the hydraulic system relief valve. We can compare these two, I believe it would be more beneficial to our understanding. Let Jiang Yi hydraulic machinery to give us a brief introduction to.

Valve is actually used to reduce the pressure of the fluid in the hydraulic system, he is not affected by the flow of imports and the effects. Of course, there are many of his characteristics in his different occasions have different structures can be converted, there are direct acting and pilot-operated two.

Then the valve and pressure relief valve difference between the two in which it?
1 valve outlet where he can keep the pressure constant, but he was in the import relief valve to keep the pressure constant place.
(2) When the job is not performed when his oil inlet valve is on, but he was out of the oil port relief valve is illogical.
3 valve he was going to skew the use of pilot valve spring chamber inside the mouth of the drain to be connected to a separate tank, relief valve which can be within the vent, not individually connected to tank.

We often use the valve to be lubricated on the road, you can also control the electric hydraulic valve circuit, but it is a loss of pressure reducing valve, and the flow rate is too large, we use high-pressure pump, respectively, conduct oil
