Example Embodiment

[0013] The present invention will be further clarified below in conjunction with the drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" "Respectively refers to the direction toward or away from the geometric center of a particular component.

[0014] It can be seen from the accompanying drawings that the present constant pressure fully enclosed pressure reducing valve includes a valve housing 14. One side of the valve housing 14 is a medium inlet 15, and the opposite side is a medium outlet 16, and the inner top of the valve housing 14 is provided with an adjusting spring 2. The upper end of the adjusting spring 2 is provided with a posi...

Abstract

The invention provides a constant pressure full-closed reducing valve comprising a valve shell. One side of the valve shell is of a medium inlet, the opposite side of which is of a medium outlet. An adjusting spring is arranged at top of the inner valve shell, a valve disk is arranged at the lower end of the adjusting spring, the periphery of the valve disk is sealed with the inner wall of the valve shell through a diaphragm, a main valve spring is arranged at bottom of the valve shell, a valve seat is arranged above the main valve spring, a partition is arranged above the medium inlet, an auxiliary valve disk is connected above the partition, feedback holes are formed in the portions of the shell above and below the auxiliary valve disk, a power cavity is formed above the auxiliary valve disk, a valve seat connecting plate is arranged between the medium inlet and the medium outlet, the valve seat is connected below the valve seat connecting plate, and the valve seat connecting plate divides the space between the partition and the valve seat into two equal spaces as a first room and a second room. Under decompressing effects of the valve seat connecting plate and the valve seat, medium pressure Pj enters the second room after the medium enters the valve shell, so that consistent pressure above and below the auxiliary valve disk is realized through the feedback holes; the adjusting spring and the valve disk perform indifference adjustment to the medium, and the adjusting 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, ...
