| description | The utility model discloses a pressure reducing valve. The pressure reducing valve comprises a valve body, a valve cover, a driving device and an execution device, wherein the valve cover is fixedly connected with the valve body, a containing cavity which is used for containing the execution device is formed by the valve body and the valve cover, an elastic baffle plate is arranged in the containing cavity, the containing cavity is divided into a first cavity and a second cavity by the elastic baffle plate, the valve body comprises a medium inlet passage which is communicated with the first cavity and a medium outlet passage which can be communicated with the medium inlet passage, and a baffle plate through hole which is used for enabling the execution device to penetrate through is formed in the elastic baffle plate; a valve seat is fixedly arranged in a junction position of the medium inlet passage and the medium outlet passage, the position, which is in leaning contact with the valve seat, of the execution device is the junction position, the driving device controls the junction position to open and close through the execution device, the execution device comprises a valve rod, a valve flap, a balance spring, a first spring seat and a second spring seat, and the balance spring, the first spring seat and the second spring seat are all located in the second cavity. The pressure reducing valve disclosed by the utility model has the advantages that the sealing performance is good, the gas-liquid interchange can be effectively controlled, and a leakage event is prevented from happening. |
