Description

Technical Field

[0001] The invention relates to an air decompression component, in particular to a two-unit air decompression component. Background Art

[0002] The air pressure reducer is one of the auxiliary units of the pneumatic unit combination instrument. It adjusts the air source from the air compressor to the required pressure value for voltage stabilization, and provides air source for various pneumatic instruments and other pneumatic equipment. The pressure reducer is a regulating device that reduces high-pressure gas to low-pressure gas and keeps the pressure and flow of the output gas stable. It can be divided into two types: direct-acting and reverse-acting. Common pressure reducers are mainly single-stage reverse-acting and two-stage mixed (the first stage is direct-acting and the second stage is reverse-acting).

[0003] The existing air decompression assembly cannot detect the ventilation air pressure when in use, so the device is easily damaged when excessive gas is introduced into the device for a long time, and the air pressure of the gas after decompression cannot be detected. Therefore, it is necessary to propose an air decompression assembly with a pressure detection structure. Summary of the invention

[0004] The present invention aims to provide a two-unit air decompression component to solve the problems of large space occupied, heavy weight and large leakage of valve and pipeline connection in the traditional mode. The decompression function can be realized through integration to greatly reduce weight and size to meet the needs of small space on board.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a two-pack air pressure reducing assembly, including an air pressure reducing assembly and a bypass valve. The two air pressure reducing assemblies are connected in parallel through the bypass valve to form a two-pack multifunctional plug-in high-pressure air pressure reducing assembly. The two-pack multifunctional plug-in high-pressure air pressure reducing assembly is installed at the rear end of the high-pressure air system for pressure reduction. The two-pack air pressure reducing assembly is integrated in a limited space to meet the narrow space environment of small boats and improve the convenience of operation. Different flow ratios can be obtained by controlling the opening of different stop valves to supply multiple users at the rear end.

[0006] Furthermore, the two-unit multifunctional plug-in high-pressure air pressure reducing assembly adopts a componentized installation method, which can improve the operating efficiency of the valve group. At the same time, different valve components can be replaced according to different user needs to meet different functions.

[0007] Furthermore, the air decompression assembly includes an air intake component, a valve body, a stop valve assembly, an air charging valve, a pressure reducing valve assembly, a safety valve, and an outlet joint. The air intake component is connected to the air charging valve and the pressure reducing valve assembly through the inlet stop valve in the stop valve assembly, and the outlet of the pressure reducing valve assembly is connected to the outlet joint through the outlet stop valve in the stop valve assembly. The air intake end of the pressure reducing valve assembly is provided with a pressure gauge and a relief valve, and the air outlet end is provided with a safety valve, a pressure gauge and a relief valve; a filter is provided in the air intake component.

[0008] Furthermore, the stop valve assembly, the inflation valve, the pressure reducing valve assembly and the safety valve are all integrated in the valve body.

[0009] Furthermore, the inflation valve is an adjustable pressure inflation valve, which can reduce the inlet pressure of 5MPa to 0-0.1MPa by adjusting the outlet pressure and is continuously adjustable. When the pressure is too high, the pressure reduction can be reversed by operating the inflation valve hand wheel.

[0010] Furthermore, the pressure reducing valve assembly includes an upper cover, a blind cover, a diaphragm, a piston disc, a reset spring, a connecting screw disc, a push rod, a valve sleeve, a main valve disc, a main valve spring, a valve seat, and a bottom cover. The main valve disc is installed in the valve seat in the valve body and is connected to the main valve disc. A valve sleeve is provided on the valve seat, a connecting screw disc is provided above the valve sleeve, and the bottom of the valve seat is connected to the valve body through the bottom cover; a main valve spring is provided between the bottom of the main valve disc and the bottom of the valve seat, the main valve disc is connected to the piston disc located above the connecting screw disc through a push rod, a reset spring is provided between the piston disc and the connecting screw disc, the top of the piston disc is connected to the diaphragm and the blind cover, and the diaphragm and the blind cover are fixed to the valve body by the upper cover through screws and spring washers.

[0011] Furthermore, the stop valve assembly includes a valve sleeve, a valve disc, a positioning block, an end cover, a valve stem, an indicator cover, and a handwheel. A positioning block is provided at the upper end of the valve sleeve installed in the valve body, and a valve disc is connected to the inside of the valve sleeve. The axis of the valve disc passes through the positioning block and is connected to the valve stem. The valve stem is threadedly connected to the end cover, and the upper end of the valve stem is connected to the handwheel; the upper part of the valve stem is connected to the indicator cover through a nut; and the end cover is fixedly connected to the valve body through screws and spring washers.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) This multifunctional plug-in high-pressure air pressure reducing assembly solves the problems of large space occupied, heavy weight, and large leakage of valve and pipeline connections in the traditional mode. By integrating the pressure reducing function, the weight and size can be reduced to the greatest extent to meet the needs of small space on board.

[0014] (2) The modular installation method can improve the operating efficiency of the valve group. At the same time, different valve components can be replaced according to different user needs to meet different functions.

[0015] (3) Large flow rate and high pressure reduction ratio. By adjusting the outlet pressure through the pressure regulating inflation valve, the inlet pressure of 5MPa can be reduced to 0-0.1MPa and it is continuously adjustable. When the pressure is too high, the inflation valve hand wheel can be used to adjust the pressure in the reverse direction. BRIEF DESCRIPTION OF THE DRAWINGS
