safety valve is used to right regulate the air pressure of air cylinder

　　Professional famous brands excavator tooth pin and rubber design and manufacturing enterprise said the main role f the safety valve is used to regulate the abnormal pressure state but maintain the inner air pressure of air cylinder never beyond 0.78MPa. But when the inner air pressure is beyond 0.78MPa and the safety valve still not release the pressure, professional famous brands excavator tooth pin and rubber design and manufacturing enterprise the air cylinder inner pressure would continue raise up, and the main reason must because of the leakage of safety valve film piece or the safety valve spring part has a too harden degree.

　　As long as the safety valve start to release pressure but the current air pressure is not match with the requirement needs, professional famous brands excavator tooth pin and rubber production and design manufacturing enterprise said it maybe caused by worse weaken property of spring part, so because of the too low pre tightening force, both of the valve and valve seat part would has a worse sealing performance, and professional excavator tooth pin and rubber supplier said the solve method is replace the old damage hurt part timely.
