Replacement Fusheng Air compressor parts Air Compressor Valves

The check valve of the compressor plays an important role in the operation of the compressed air system. Check valves are located between the compressor and the tank or main manifold to prevent air from flowing out of the tank or main manifold and back into the inlet line when the compressor is shut down. At the same time, the pressure relief valve allows air to flow out of the compressor piping to reduce load at startup.

Typically, check valves consist of a valve mechanism that maintains the seal of the head when the pressure in the head is higher than on the side of the compressor. As a result of this design, faulty check valves may sometimes leak at lower pressures but not at higher pressures.
In fact, leaks can often be traced back to faulty check valves.

Clean the return oil check valve

(1)Composition of one-way valve: One-way valve is composed of valve body, steel ball, steel ball seat, spring and other components.

(2) Function of return oil check valve:
Host compressing the mixture of oil and gas in YouQiGuan first preliminary separation by centrifugal force, because the oil is greater than the weight of the air, most of the oil in a solid mixture of oil and gas to oil tank by centrifugal force, screw air compressor under the action of internal pressure back to the host for the lubrication cycle, and contain a small amount of compressed air by the oil and gas separator of oil separation again, this time separation of oil and gas separator lubricating oil will fall to the bottom of the oil and gas separator, in order not to let this part of the oil with compressed air away, the units used in the design of a pipeline inserted into the bottom of the oil and gas separator, through the internal pressure, the introduction of this part of the oil directly into the host lubrication,
And the pipeline has a one-way valve, screw air compressor called return oil single valve, its role is to smoothly recover oil from the oil and gas separator to the main engine without letting the oil from the main engine flow back to the oil and gas separator.

(3) Return oil single valve removal: in the valve body has a joint, from where unscrew, take out the spring, ball, ball seat.

(4) Cleaning return oil check valve: clean valve body, spring, steel ball, steel ball seat with cleaning agent. Some check valves also have filter net inside. If there is any, clean together.

(5) Assembly of return oil check valve: install check valve according to the reverse steps of disassembly.

(6) The check valve shall be put aside to be loaded into the air compressor after the whole cleaning process is completed
