The angle stop valve can effectively improve the learning efficiency of management work and effectively save resource costs. Therefore, it plays a good role in the pipelines of many small and medium-sized enterprises. How can the angle stop valve be used for a long time?

Before use, clean the pipeline and body flow-through parts with water to prevent residual iron filings and other sundries from entering the body cavity. When it is closed, there are still some residual media in the valve body, and it is also under a certain pressure.. before overhauling the three-way ball valve, close the stop valve in front of the three-way ball valve, open the three-way ball valve to be overhauled, and completely release the internal pressure of the valve body. If the check valve, Disconnect the air source first. Generally, the soft sealing three-way ball valve is used as the sealing material, and the sealing surface of the hard sealing three-way ball valve is metal surfacing. If it is necessary to clean the pipeline three-way ball valve, pay attention to prevent damage to the sealing ring and leakage during disassembly. During disassembly and assembly, the bolts and nuts on the flange shall be fixed first, and then all the nuts shall be tightened slightly, and then fixed with strength.. if individual nuts are forcibly fixed first, and then other nuts are fixed, the flange surface will be damaged or broken due to uneven lining, resulting in leakage of valve flange butt medium.. if the valve is cleaned, the solvent used shall not conflict with the accessories to be cleaned, No corrosion.

Lift check valve can be divided into swing check valve (rotating according to the center of gravity) and lift check valve (moving along the axis). Carbon steel check valve is used as boiler feed water and steam shut-off valve. It has the comprehensive function of lifting check valve, stop valve or angle valve.

Swing check valves can also be used in pipelines to supply auxiliary systems in which the pressure may rise above the system pressure. If it is a special three-way ball valve for gas, it can be cleaned with gasoline.. other parts are generally cleaned with reclaimed water.. clean the residual dust, oil and other attachments. If clean water cannot be cleaned, it shall be cleaned with alcohol and other cleaning agents on the premise of not damaging the body and parts.. after cleaning, the cleaning agent will volatilize completely before assembly.

If the packing is found to have slight leakage during use, the valve stem nut can be tightened slightly until the leakage stops, and can not be further tightened.. long term open storage will cause rust of valve body and parts and can not be used normally

The storage of three-way ball valves shall be rainproof, waterproof and moisture-proof, and the flange cover shall be tight. The valves stored for more than 12 months shall be retested during use to ensure stable performance.

Therefore, in addition to correct use and reasonable maintenance, it is also very important to check the valve in use to ensure its service life.
