Abstract
The invention relates to a novel spring control valve. The valve comprises a valve body, an inner sheath, a valve core, an elastic sleeve, a valve rod, a valve cover, a filler and a pneumatic film actuating mechanism, wherein the elastic sleeve is arranged on the outer side of the valve rod, the filler is arranged in the valve cover, the upper part of the valve rod is connected with the pneumatic film actuating mechanism, the pneumatic film actuating mechanism comprises a spring, a film and a cylinder, the spring is symmetrically arranged on two sides of the upper part in the pneumatic film actuating mechanism, the film is arranged below the spring, a pressing plate is arranged between the film and the spring, the lower part of the cylinder is connected with the valve rod and is coaxially arranged with the valve rod, the upper part of the cylinder is arranged below the film, and the elastic sleeve is an elastic corrugated pipe. The invention has the advantages of simple structure, small pressure drop loss, large flow capacity, visual display, convenient adjustment, large adjustable range, high flow control precision, good anti-seismic performance, low production cost and long service life.
Description
Technical Field
The invention relates to a valve, in particular to a novel spring control 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.
