【Q&A Question 236】August 30, 2018: Briefly explain the reasons for the heating of the intake valve How to eliminate it? The main reasons for the overheating of the compressor’s suction valve are as follows: ① Incorrect valve assembly ； ②The valve disc is broken or the spring has failed ； ③Failed valve gasket or missing gasket ； ④A foreign object is stuck in the valve disc ； ⑤The intake air temperature is too high. The elimination methods are: ① Reassemble the gas valve ； ②Replace wear parts ； ③Replace or refill the gasket ； ④Remove foreign objects ； ⑤Reduce the intake air temperature.

The suction valve of the compressor? There is likely a leak in the pressure valve, allowing gas from the high-pressure side to flow back to the low-pressure side, which increases the temperature of the intake valve.
Reasons for the heating of the intake valve: 1. High intake air temperature, which causes the intake valve to heat up. Solution: Contact the upstream equipment to reduce the temperature. 2. Poor cooling performance of the inter-stage cooler, resulting in high intake air temperature in the subsequent stage and thus high valve temperature. Solution: Increase the flow rate of the circulating water; if scaling in the cooler is the cause, the cooler tube bundles need to be descaled after switching the compressor. 3. Internal leakage in the suction valve causes compressed gas to flow back to the inlet. Solution: Switch the compressor and service the suction valve

1. Improper assembly of the intake valve, with loose fitting; 2. Damaged valve disc or failed spring; 3. Missing gasket or no gasket at all; 4. The valve is too dirty or assembled loosely; 5. Metal fragments or other debris on the valve disc; 6. Excessively high intake temperature
The main reasons for the overheating of the compressor’s suction valve are as follows: ① Incorrect valve assembly； ②The valve disc is broken or the spring has failed ； ③Failed valve gasket or missing gasket ； ④A foreign object is stuck in the valve disc ； ⑤The intake air temperature is too high. The elimination methods are: ① Reassemble the gas valve ； ②Replace wear parts ； ③Replace or refill the gasket ； ④Remove foreign objects ； ⑤Reduce the intake air temperature.
① The intake valve is improperly assembled or not sealed properly; ② The valve disc is damaged or the spring has failed; ③ Gaskets are missing or not present; ④ The air valve is too dirty or not assembled tightly enough; ⑤ Metal fragments or other debris are lodged in the valve disc; ⑥ The intake temperature is too high. The solutions are: ① Repair or replace the valve disc, spring, or the entire air valve; ② Remove metal fragments or other debris and clean/assemble the valve again; ③ Install new gaskets; ④ Find a way to reduce the intake temperature
The air valve is leaking, or the gasket between the air valve and the valve seat is leaking; replace the valve disc and spring of the air valve, or replace the gasket between the air valve and the valve seat
① The intake valve is improperly assembled or not fitted tightly; ② The valve disc is cracked or the spring has failed; ③ Gaskets are missing or not present; ④ The air valve is too dirty or assembled loosely; ⑤ Metal fragments or other debris are stuck in the valve disc.
