Technical Field

The invention relates to a regulating valve, in particular to a nozzle water inlet control regulating valve.

Background

A closed circulating cooling water regulating valve relates to a cooling water regulating valve, which is widely used in industrial industries such as power stations, metallurgy, petrochemical industry and the like, provides clean and stable cooling water for various main and auxiliary machines to control various main and auxiliary machine cooling media, controls the temperature of a bearing within a certain range, and ensures the safe and reliable operation of various main and auxiliary machines, such as an air cooler, a hydrogen cooler, an oil cooler and other various auxiliary machine bearings to provide cooling water quantity. If the temperature is high, the adjusting valve is opened to increase the water supply amount, and if the temperature is too low, the cooling water amount is reduced, so that the normal operation of various main and auxiliary machines is ensured.
