Daily maintenance of electric valves - Dalian Hongbo Power Engineering provides answers

Electric Valve The operating torque is greater than that of ordinary valves. The opening and closing speed of the electric valve can be adjusted. It has a simple structure, is easy to maintain, and can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Traditional pneumatic valves, however, due to the buffering characteristics of the gas itself during operation, are not easily damaged by jamming, but they must have an air source, and their control system is also more complex than electric valves. These valves should generally be installed horizontally in the pipeline. So how to do daily maintenance of electric valves? Dalian Hongbo Electric Power Engineering Co., Ltd. Let's talk!

Daily Maintenance of Electric Valves

1. Electric valves should be stored in a dry and ventilated room, and both ends of the passage should be blocked.
2. Electric valves stored for a long time should be inspected regularly, cleaned of dirt, and anti-rust oil applied to the machined surfaces.
3. After installation, regular inspections should be carried out. The main inspection items are:
(1) Wear condition of the sealing surface.
(2) Wear condition of the trapezoidal threads of the valve stem and valve stem nut.
(3) Whether the packing is outdated and失效, and replace it immediately if damaged.
(4) After the electric valve is inspected and assembled, a sealing performance test should be carried out.

In operation Electric Valve All valve parts should be complete and intact. Flange threads and bolts on the bracket cannot be missing, and the threads should be intact and undamaged; loosening is not allowed. Hand-tightened nuts, if found loose, should be tightened immediately to prevent wear on the connection or loss of the handwheel and nameplate. If the handwheel is lost, it is not allowed to be replaced with an adjustable wrench; it should be replenished in time. The packing gland is not allowed to be skewed or without pre-tightening clearance. For electric valves in environments easily contaminated by rain, snow, dust, sand, etc., the valve stem should be equipped with a protective cover. Electric Valve The scale on the should be kept intact, accurate, and clear. The lead seal, cap, pneumatic accessories, etc. of the electric valve should be complete and intact. The insulation jacket should be free of dents and cracks. It is not allowed to knock, stand people, or support heavy objects on the running electric valve; this is especially true for non-metallic electric valves and cast iron Electric Valve This is even more prohibited.
