The importance of valve repair

A long time, most of the domestic industry based on the new replacing the old, replaced the valve when the waste thrown away or sold, especially with flange valve industry, and replaced the high pressure, high temperature, valve want repair, but do not know how to repair it. The majority still remain in the manual repair stage. Can be said that China's valve repair industry, waste and the availability of benefits are enormous.
A power station to repair each year tens of thousands of steam turbine valves and bypass valves. Only one power plant imported from Germany in 1992, grinding machine, the rest are manual, not only inefficient, but mainly the precision. The bypass pressure relief valve leakage, power plants can not be repaired, sent to repair the effect is not ideal.two position three way valve
In recent years, with the various units gradually began independent economic accounting, reduce costs, from management to front-line maintenance workers have gradually realized the importance of valve repair, because this can save funds is extremely impressive. However, valve repair here does not refer to the simple repair, also including the use of correct repair methods and excellent grinding repair equipment.high temperature solenoid valve
Valve repair and overhaul of the concepts and lack of equipment, the only nuclear power plant in the country can basically do all valves in each downtime during maintenance. Bad repair is a preventive maintenance, which is extremely unfavorable for the safe operation of the full set of equipment and the life of the valve, and its potential emergency outage is extremely lethal, the resulting loss is huge . For example: a petrochemical 1 set full set of imported production equipment from Germany, commissioned from 1981 to 1996 never been repair in 1996, found several key filler valve leakage, and German manufacturers no longer produce the special valves, if re-ordering is not only expensive, but very long delivery period, brought about huge economic losses. So, industrial high temperature and high pressure valve for preventive maintenance and repair measures, is the solution to valve leakage and extend the life of the most economical and reliable way.pneumatic hand valve
