Abstract
The utility model discloses a gas pressure reducing valve, which relates to a gas pressure reducing device used for reducing high pressure gas in a gas cylinder or a pipeline to working pressure. The utility model is composed of a valve body, a valve cover, a rubber diaphragm and a pressure regulating screw. The upper part of the valve body is provided with a low pressure chamber and the bottom of the valve body is provided with a high pressure chamber. A hexagonal regulating valve and a regulating valve seat are arranged in the high pressure chamber. The bottom of the rubber diaphragm is provided with a push rod matching with the hexagonal regulating valve. Rotating the pressure regulating screw can adjust the working pressure of the low pressure chamber through a regulating spring and the rubber diaphragm. The utility model has the advantages of convenient assembly, maintenance and replacement of parts and long service life, so the utility model is especially suitable for a pressure reducing device for high pressure gas, such as high pressure oxygen, high-pressure acetylene, etc.
Description
The utility model relates to a kind of being used for the decompressor of the high pressure air reducing in the gas cylinder or in the pipeline to working pressure.
In gas welding, cutting and other similar technology, high pressure air bodies such as high pressure oxygen in the gas cylinder or in the pipeline or acetylene gas need be decompressed to working pressure, and when incoming pressure and rate of discharge change, keeping the stable of working pressure, gas pressure reducer promptly is one of device of realizing decompression and voltage stabilizing.Gas pressure reducer of the prior art mainly is made of valve body, valve gap, diaphragm of rubber and pressure screw pitch screw, and utilizes the principle of diffusion decompression to realize decompression.Valve body is divided into hyperbaric chamber and low pressure chamber two-part, and the hyperbaric chamber is suitable for reading for valve seat with holes and have the air inlet that is communicated with it and chew and the air inlet high pressure gauge, and low pressure chamber is suitable for reading to be utilized the diaphragm of rubber sealing and have giving vent to anger of being communicated with it and chew and give vent to anger low-pressure meter.In order to control the diffusion of pressurized gas, one or six side's modulating valve and springs are housed also in the hyperbaric chamber.Pressure regulating screw is installed in the top of valve gap, manually during the rotary pressure adjusting screw, can push diaphragm of rubber and the push rod by diaphragm of rubber bottom promotes six side's modulating valve by Regulation spring, thus the diffusion of control pressurized gas and adjust the low pressure chamber working pressure.From a structural point, present existing gas pressure reducer adopts external-mounted structure more, and parts such as six side's modulating valve and spring are packed in the hyperbaric chamber by the bottom of valve body and adopted the rigid Sealing of disposable assembling to be sealed.Such structure is the assembly technology complexity not only, and sealing also goes to pot easily.In addition, because valve seat directly processes on valve body, very easily the wearing and tearing because of valve seat cause whole valve body to be scrapped.
The purpose of this utility model promptly is the improvement in addition suitable to the structure of gas pressure reducer, with convenient for assembly, maintenance with change parts, prolongs the whole service life of reduction valve.
To achieve these goals, it is the built-in type structure that the utility model changes external-mounted structure, and six side's modulating valve and spring and valve seat and Sealing are packed into by the suitable for reading of valve body.Like this, not only can cancel the rigid sealing of valve body bottom, and make assembling, maintenance and the replacing of six side's modulating valve, spring and valve seat convenient.Be described in further detail below in conjunction with the technical characteristics of specific embodiment the utility model gas pressure reducer.
Accompanying drawing 1 is the structural representation of the utility model gas pressure reducer.
With reference to the accompanying drawings 1, the utility model gas pressure reducer mainly is made of valve body, valve gap, diaphragm of rubber and pressure regulating screw.Valve body 1 is cylindrical, and its bottom center is hyperbaric chamber 2 and has with it the air inlet that is communicated with and chew 3 and the air inlet high pressure gauge.Six side's modulating valve 4 of working in coordination with it and can move up and down therein are housed in the hyperbaric chamber 2, a spring 5 is equipped with in the below of six side's modulating valve 4, the regulating valve seat 6 of band center hole then is equipped with in the top of six side's modulating valve 4, and regulating valve seat 6 closely cooperates with valve body 1 and utilizes Sealing 7 reliable sealings.The top of valve body 1 is that giving vent to anger of being communicated with of low pressure chamber 8 and have with it chews 9 and the low-pressure meter of giving vent to anger.Diaphragm of rubber 10 is installed in the suitable for reading of valve body low pressure chamber 8 and with low pressure chamber 8 sealings, its top has the latch plate 11 that fuses with it, and its below then has the push rod 12 that passes regulating valve seat 6 center holes and work in coordination with six side's modulating valve 4.Valve gap 13 is a hollow circle tube, and its bottom and top have the screw thread of working in coordination with valve body and pressure regulating screw respectively.Pressure regulating screw 14 be installed in valve gap 13 the top and with valve gap 13 screw-thread fit, its top has a rotatable handle 15, and the Regulation spring 16 of working in coordination with pressure regulating screw 14 and diaphragm of rubber latch plate 11 is housed in the valve gap of pressure regulating screw 14 belows.
When opening reduction valve, rotary pressure adjusting screw 14 clockwise, by Regulation spring 16 pushing latch plates 11 and diaphragm of rubber 10 and make six side's modulating valve 4 leave regulating valve seat 6 by push rod 12 to form airflow clearance, pressurized gas promptly enter low pressure chamber 8 diffusion decompressions via regulating valve seat 6 center holes.When need regulating low pressure chamber 8 working pressures, can clockwise or counter-clockwise rotary pressure adjusting screw 14, make in the diaphragm of rubber 10 below low pressure chambers 8 with it that the pressure of balance changes, reach the purpose of adjusting working pressure.When closing reduction valve, should be totally released pressure regulating screw 14, make the self-return sealing under the effect of pressurized gas and spring 5 of six side's modulating valve 4, prevent that pressurized gas are to low pressure chamber 8 diffusions.
The utility model assembling is keeped in repair, the replacing parts are all very convenient, and whole service life is long, so be particularly suitable for as high pressure air body decompressors such as oxygen, acetylene.
