Valves in the process of use and management of long-term development, affected by the environment medium friction, there will be a lot of different culture degree of wear and tear, which can affect the service life of the enterprise actual, so what's the teaching methods for us to extend the service life of the check valve? We will with manufacturer to see together. Check valve disc around the seat to the clamp pin shaft rotate within the check valve. Disc check valve has simple structure, can only be installed in horizontal pipe runs, sealing is good. High temperature check valve belongs to a kind of automatic valve, main effect is to prevent the backflow medium, to prevent the pump and drive motor reversal, and the discharge of the container medium. Lift check valve can be divided into main swing check valve ( In accordance with the center of gravity rotating) And lift check Industrial Valves ( Move along the axis) 。 Before use, clean water pipeline and ontology flow components, prevent the residual iron filings and other debris into the cavity in the body. 。 Closed, the body there are still some residue medium, also under certain pressure. 。 Overhaul three-way ball valve before, shut off the tee ball valve in front of the cut-off valve, open the need to overhaul the three-way ball Industrial Valves, complete internal pressure release valve body. 。 If is pneumatic three-way ball Industrial Valves or check valve, should first disconnect the power and air supply. 。 General soft sealing three-way ball valve adopts four fluorine ( PTFE) As the sealing material, hard sealing three-way ball valve sealing surface surfacing metal. 。 If you need clean pipe tee ball valve, pay attention to prevent damage to seal leakage during disassembly. 。 When disassembling, should first to fasten on the flange bolt and nut, then all of the nut is a bit tight, with strength at last. 。 If the individual nut to fixed first, and then fixed other nut, flange surface is caused by uneven lining damage or breakdown, lead to valve flange butt medium leakage. 。 If the valve is clean, use the solvent shall not conflict with to clean the parts, shall not be corrosion. If it is a special three-way ball valve, gas can be cleaned with gasoline. 。 Other parts of general use water to clean. 。 When cleaning, thoroughly clean the residual dust, grease and other attached objects, such as water can not clean, under the premise of without causing damage to the body and parts, targeted with alcohol and cleaner. 。 After cleaning, the cleaner completely evaporate before assembly. If in use process found a slight leakage, packing can be a little tight stem nut, until the leak stops, not further tighten. 。 In open air for a long time, can cause the body and parts of rust, can't normal use. 。 Three-way ball valve deposit should be waterproof, waterproof, moistureproof, and flange cover tightly. 。 Stored more than 12 months of the valve when used to test, to ensure stable performance. So, the service life of the one-way valve can through these methods, better for people to expand production.
