The constant pressure fully enclosed pressure reducing valve includes a valve casing. One side of the valve casing is the medium inlet, and the opposite side is the medium outlet. The top of the valve casing is equipped with an adjusting spring, and the lower end of the adjusting spring is equipped with a valve disc. The surrounding area is sealed with the inner wall of the valve housing through the diaphragm. The bottom of the valve housing is provided with a main valve spring, a valve seat is provided on the main valve spring, a baffle is provided above the medium inlet, and an auxiliary valve disc is connected above the baffle. Feedback holes are provided on the upper and lower valve casings, and a power chamber is formed above the auxiliary valve disc; a valve seat connecting plate is provided between the medium inlet and the medium outlet, and the valve seat is connected to the bottom of the valve seat connecting plate, and the valve seat connecting plate connects the baffle and the medium outlet. The space between the valve seats is divided into two equal halves, namely the first chamber and the second chamber. In the present invention, after the medium enters the valve casing, the pressure Pj of the medium enters the second chamber after being decompressed by the valve seat connecting plate and the valve seat, and then passes through the feedback hole to realize the consistent pressure of the upper and lower sides of the auxiliary valve disc, and adjust the pressure of the spring and the valve disc. There is no differential adjustment to the medium. The adjustment effect is stable.
Description
technical field [0001] The invention relates to a constant-pressure fully-enclosed decompression valve, which is a constant-pressure load, injection-type, fully-enclosed, auxiliary valve-type decompression valve, which belongs to the field of valves. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel valves, ...
