Abstract
The utility model discloses a temperature and pressure reducing valve which comprises a valve body, a first sealing gasket, a valve cage, a valve plug, an atomizing nozzle, a second sealing gasket, a valve cover, a lower filler assembly, a lower filler press cover, a third sealing gasket, an upper valve cover, a flange, an upper filler press cover, an upper filler assembly, a valve rod, a first small hole, a second small hole and a water feeding connection pipe. The temperature and pressure reducing valve has the advantages of integrating pressure reducing and temperature reducing, only requires one set of motor-driven or pneumatic execution mechanism and facilitates installation and centralized control. The pressure reducing portion adopts the two-stage porous valve cage and can effectively reduce noise and protect the valve body. The temperature reducing portion adopts the design of an adjustable water feeding valve rod.
