The Warner steam pressure reducing valve, high-quality sales Tel :0571 -64288596 Website: http://www.hnkzf.com. 
 The Tonglu Warner Valve Co., Ltd. produces high quality steam pressure reducing valves, steam pressure reducing valve is divided into several types, each of the different functions. Warner's steam decompression is composed of two parts by the main valve and pilot valve. The main valve seat, the main valve plate, piston, springs and other parts. Pilot valve is mainly composed of the parts of the valve seats, valve, diaphragm, spring, adjusting spring. This product is made in the ordinary pressure reducing valve on the basis of greatly improved, to increase the piston area, change the structure of the throttle. Change the seal in the form, increase the flow area, thereby improving the sensitivity, flow, and other aspects of life has greatly improved the performance. 
 This product is mainly used for steam piping, apply to the traffic flow changes, changes in inlet pressure steam piping. 

 First, the valve works 
 The pressure reducing valve is a specialized device to automatically reduce pipeline pressure, high water pressure in the pipeline valve before it can be reduced to the level of the valve after the piping required. The valve is widely used in high-rise buildings, urban water supply network water pressure is too high areas, mines and other occasions, in order to ensure the water supply system water point of access to appropriate pressure and flow. In view of the water loss rate and extent of waste is almost the same pressure is proportional to the size of the water supply system, therefore reducing valve to improve the system operating conditions and potential water-saving role, according to statistics, the saving effect of about 30%. 
 Constructed type of valve past common thin film, the inner spring piston. The pressure reducing valve, the basic mechanism is to rely on the local resistance of the flow channel on the flow valve to reduce water pressure, water pressure drop range automatically adjust the import and export the water pressure by connecting the valve film or both sides of the piston. In recent years, some new pressure reducing valve, such as fixed ratio pressure reducing valve, the fundamentals of the structure shown in Figure 14.2-2 shown. Given decompression principle is the use of body floating piston in the hydraulic pressure than the control, import and export of side decompression than to import and export side of the piston area is inversely proportional to. This pressure reducing valve work smoothly without vibration; the valve body spring, so spring corrosion, metal fatigue failure of the consideration; good sealing performance, no leakage, and thus both less dynamic pressure (water flow) also reduced static pressure (flow rate 0:00); especially in the decompression at the same time does not affect the water flow. 
 It should be noted that although a lot of head loss in flow through the valve, but due to the reduction of water waste and make the system flow distribution is reasonable to improve the system layout and operating conditions, so generally speaking the energy-saving.
