Relevant to the maintenance of gas valves in reciprocating compressors
Thread Content
Model: 4M80; Medium: coke oven gas; Valve type: ring valve; Manufacturer of the unit: Shengli Blower. Reason for seeking assistance: The unit has been in operation for 3 years, and the routine maintenance of the valves has consisted only of cleaning and leak testing using water. Over time, I feel that more thorough maintenance of the valves is necessary, for example by creating a specialized tool for pressure testing these valves. I wonder if any of the sailors here have made a pressure testing tool for air valves. If so, I would be extremely grateful; please share your knowledge so that we can all learn from it*. Thank you in advance. Or send to my email: bgqhjc@163.com
Why suppress the air valve? You can use kerosene to check for leaks; that’s what manufacturers do.
Let’s stick to the old traditional methods; think things through first, and then innovate.
Pressure testing for leak detection is done to better control the height of the lift mechanism, ensuring that the valves can open and close at the specified pressure.
What organization are you from? Can a clearance energy-saving product be installed on the 4M80 compressor unit?

It depends on the specific usage conditions; the properties of the medium have the greatest impact on the gas valve, and ring valves already possess relatively the best flow capacity. After 3 years of operation, it is indeed necessary to strengthen the inspection of the air valves; however, I believe that simply cleaning them and testing for leaks with water is not sufficient. Due to limitations in the structural design and the material of the valve bodies, the typical replacement period for these air valves is around 3 operating cycles. The reply above already recommends using kerosene for leak testing, but it is still advised to consider replacing the gas valve at around the time when its replacement is due, as the gas valve is a critical component.
