Type of valve has a lot of, different type of valve is not only a functional analysis, maintenance method research is through the different, so for us to how to choose the right for maintenance? Today the factory took everybody know together. Pneumatic Industrial Valves disc sliding along the center line of the body of the valve. Pipeline check valve is a new kind of valve, its small size, light in weight and good processing technology, is one of the check valve development direction. But the fluid drag coefficient is slightly superior to swing check valves. Carbon steel check valve is the valve is used as boiler feed water and steam to cut off the valve, it can lift check valve and globe or Angle valves of the comprehensive function. American standard check valve according to the conditions of use, valve can be all-metal structure, can also be embedded in disc shelves rubber mat or rubber ring form. 1. General soft sealing four fluorine ball valve are used as the sealing material, hard seal ball Industrial Valves sealing surface of the metal welding. 。 If the pipeline ball valves need to be cleaned, be careful when removing, prevent damage seal leakage. 。 2. If the valve is clean, the solvent used shall not conflict with to clean the parts, shall not be corrosion. If it is a special gas ball Industrial Valves, can use gasoline to clean. 。 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. 3. In open air for a long time, can cause the body and parts of rust, can't normal use. 。 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. 4. Ball valve in the closed state, the body still remain part of the media, also under certain pressure. 。 Maintenance before the ball valve, close the ball valve in front of the cut-off valve, open the need to overhaul the ball valve, complete internal pressure release valve body. 。 If it is or pneumatic ball valves, pneumatic ball valve shall be cut off the power supply and air supply. 。 5. If there is a slight leakage in use in the process of packaging, stem nut can be a bit tight, until the leak stops, can't continue to tighten. Different valve, such as during the period of maintenance, need to make these details, in order to ensure the good performance of the valve.
