Maintenance of globe valve needs to pay attention to safety matters

When the high pressure angle globe valve fails, it needs time to be repaired, so what should be paid attention to when repairing? let us know. The high-pressure angle globe valve can realize proportional adjustment. It can be used together with the two-position five-way solenoid valve  the control box to realize on-off control. The V-shaped ball valve core is designed with a V-shaped notch with a special shape, which has accurate interception  physical properties. Control function, suitable for various control occasions. The upper limit of the flow volume of the electric cut-off ball valve: due to its streamlined line  full quarter-turn control, the upper limit of the volume is particularly high, the flow capacity is particularly large,  the flow resistance is small, so a smaller  more economical valve can be used. size. Electric explosion-proof gate valve has excellent adjustment characteristics: V-shaped ball valve has approximately equal percentage flow characteristics  an adjustable ratio of up to 300:1. Therefore, V-shaped ball valve can provide accurate control within a wide range of changes.

Generally, tetrafluoroethylene is used as the sealing material for soft sealing pneumatic valve,  the sealing surface coating of hard sealing pneumatic valve is made of metal. For cleaning pipe pneumatic valves, be careful when removing rings to prevent damage  leaks. When servicing a valve, the valve needs to be cleaned, the solvent used should be cleaned  the fittings should  conflict  corrode. If gas is used for pneumatic valves, this gas can be used for cleaning. Other parts can usually be washed with water. Cleaning, washing Clean residual dust, grease  other accessories, such as with water can  be cleaned without damaging the tank  parts, targeted with alcohol  other cleaning agents. The third is that in the process of packaging leakage, it is found that at most the stem nut can be tightened in a small step to stop the leakage  cannot continue to be tightened. IV. Before use, wash the flow portion of the hose  valve body with water to prevent residual iron  other debris  entering the body cavity. V. In the closed state of the pneumatic valve, the valve body is still part of the media  is also under pressure. During valve inspection, before the shut-off valve closes the pneumatic valve, when the opening of the pneumatic valve requires maintenance, the internal pressure of the valve body is completely released.

Therefore, when repairing pneumatic ball valves, we need students to pay attention to these details, so as to ensure that the valve can play an important role normally.
