How to make the performance of stainless steel flange valve stable

stainless steel flange ball valve is a widely used in the valve of a general stainless steel valve, the use of large, fast consumption, so, reasonable maintenance, otherwise can improve work efficiency, but also can reduce maintenance time, save replacement costsWant to make the performance of stainless steel ball valve stable, long-term life, need to pay attention to the following factors:stainless steel flange ball valve performance stability
1, if the stainless steel valve cleaning, the use of solvents and to clean the accessories do not conflict, do not corrodeIn the case of a gas-specific ball valve, gasoline can be cleanedOther components are generally cleaned with medium waterWhen cleaning, thoroughly clean the dust, oil and other attachments, such as clean water can not be cleaned, can not damage the valve body and parts under the premise of targeted cleaning with alcohol and other cleaning agentsAfter cleaning, wait for the cleaning agent to be completely volatile before assembly2General soft-sealed stainless steel ball valves are using tetrafluoride (PTFE) as a sealing material, hard-sealed ball valve sealing surface for metal weldingIf the pipe ball valve needs to be cleaned, care should be taken to prevent leakage from damage to the seal3Before use, apply water cleaning pipes and valve body overcurrent parts to prevent residual iron chips and other debris from entering the valve cavity4Long-term open storage, will cause the valve body and components rust, can not be used properlyBall valve storage should be rain-proof, waterproof, moisture-proof, and the flange cover tight Stainless steel valves stored for more than 12 months should be retested when used to ensure stable performance 5 When the flange stainless steel ball valve is unpacked, the bolt nut on the flange should be fixed first, then all nuts are slightly tightened, and then secured with strength If the individual nuts are first firmed, and then fixed other nuts, between the flange surface will be caused by indifference to the pad surface damage or rupture, resulting in the valve flange butt out of the media leakage 6 If a slight leak is found at the filler during use, the stem nut can be tightened slightly to the point of leakage stop, not to continue tightening 7 Stainless steel ball valve in the closed state, the valve body is still residual part of the medium, but also under a certain pressure Before opening the ball valve, first close the shut-off valve in front of the ball valve, open the ball valve that needs to be repaired, and fully release the internal pressure of the valve body If it is an electric ball valve or a pneumatic ball valve, the power supply and air supply should be disconnected first
