The utility model discloses a characteristics lie in the combination of one -level pressure relief device and second grade pressure relief device in same body, the doublestage decompression forms integratively, high -pressure gas carries out the doublestage decompression through firsts and seconds pressure relief device, manufacturing cost is practiced thrift to the continual and steady and high -usage of delivery pressure.
Description
Technical field
This utility model relates to a kind of gas pressure reducer, refers in particular to the decompressor having high-precision requirement to gas output pressure and flow.
Background technology
Gas pressure reducer is a kind of device that gas in gas cylinder carries out decompression and Flow-rate adjustment.The kind of gas pressure reducer is a lot, is used in different places, gas with various, and the requirement to decompressor is the most different, when using gas pressure reducer, needs gas constant-pressure stable to export.At present gas pressure reducer generally individually uses following two structure:
1, single-stage pressure reducing, the problem so brought is: gas can not stablize constant voltage output, and gas cannot make full use of, and causes the unnecessary wasting of resources, affects production efficiency and product quality；
2, split two stage pressure reducing, although this structure solves gas and stablizes the problem of constant voltage output, but makes the production cost of decompressor own be greatly improved, is unfavorable for marketing and application.
Utility model content
In order to solve above problem of the prior art, the purpose of this utility model is to provide one and is applicable to two-stage integrated formula gas pressure reducer, is particularly suited for the working space having high-precision requirement to gas outflow amount and pressure.
The technical solution of the utility model is: a kind of novel two stage integrated air decompressor, including body, inlet suction port, decompressing unit, low pressure gauge, high-pressure manometer, air outlet adapter and relief valve.High-pressure manometer and low pressure gauge are screwed onto on body.
Described inlet suction port includes air inlet extension bar, filter, nut, air inlet packing ring, and air inlet extension bar is screwed onto on body, and the inlet end of air inlet extension bar is provided with filter, air inlet packing ring and air inlet nut.Air inlet packing ring is for preventing air inlet extension bar from connecting gas leakage.
Described decompressing unit includes one-level decompressor, second depressurized device and upper cover.One-level decompressor is made up of bonnet, piston and spring.Spring housing props up body at piston centre, and bonnet is screwed onto on body, and plays a supporting role piston, and piston one end seal contacts with body inlet end.Second depressurized device is made up of valve, bottom spring, valve base, diaphragm unit and adjusting means.Valve is arranged in valve base, and valve base is threadedly attached on body, an end seal central contact diaphragm unit of valve, and the other end props up bottom spring.Valve is contacted with diaphragm unit by gas outlet, valve base center, and one-level decompressor and second depressurized device combine in same body, and two stage pressure reducing forms one.Adjusting means is provided with handwheel, upper cushion block, lower cushion block and regulation spring composition.Upper cushion block is by top cap catcher wheel, and the other end props up regulation spring, and regulation spring bottom props up lower cushion block, and lower cushion block contacts with diaphragm unit.Upper cover is screwed onto on body.
Described air outlet adapter includes that outlet connection, flexible pipe nut, hose coupling, air outlet adapter one are spirally connected on body, and other end is spirally connected flexible pipe nut, and air outlet adapter is arranged in flexible pipe nut.
Described relief valve includes sealing gasket, spring and relief valve screw.Sealing gasket is arranged and relief valve entrance, and one, relief valve screw is spirally connected with body.
The beneficial effects of the utility model are:
Two-stage integrated formula gas pressure reducer of the present utility model is connected with source of the gas, and gas enters second depressurized device by one-level decompressor, and bleed pressure output is stable.Piston and two kinds of decompressors of diaphragm are connected, and save production cost.
