Description

Gas pressure reducer

Technical field

The utility model relates to a kind of gas pressure reducer that reduces gas pressure, belongs to the Gas pressure reducer technical field.

Background technique

Gas pressure reducer is a kind of by the high pressure bottled gas being reduced pressure and the controlling device of flow control, be in metal gas welding, the gas cutting work than indispensable common equipment, be widely used in fields such as machine-building, petrochemical industry, health care and daily life.General common gas pressure reducer comprises decompressor body, out splice going splice, output nut, hose coupling, input adapter, the decompressor body is provided with high pressure admission passage, hyperbaric chamber and low pressure outlet passageway, described out splice going splice is connected in proper order with the low pressure outlet passageway, input adapter is connected with the high pressure admission passage, high pressure admission passage, hyperbaric chamber and low pressure outlet passageway are connected in proper order, the spool that matches with the hyperbaric chamber gas outlet is arranged in the hyperbaric chamber, the spool lower end is provided with spring, and the spool upper end connects spring, adjusting handle and pressure gauge.

The gas pressure reducer of said structure, fast from gas pressure height, flow velocity that the high pressure admission passage enters, very easily impact spool, cause air turbulence in the hyperbaric chamber, cause low pressure outlet passageway air-flow instability; Air-flow directly impacts spool, causes gauge hand to rock, and misregister influences proper functioning.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of assurance low pressure outlet passageway steady air current, pressure gauge to indicate accurate gas pressure reducer.

Technical solution adopted in the utility model is: a kind of gas pressure reducer, comprise decompressor body, out splice going splice, input adapter, the decompressor body is provided with high pressure admission passage, hyperbaric chamber, low pressure chamber and low pressure outlet passageway, is provided with the spool that can control hyperbaric chamber and low pressure chamber disconnection or UNICOM in the hyperbaric chamber; Described out splice going splice, low pressure outlet passageway and low pressure chamber are connected in proper order, and input adapter, high pressure admission passage and hyperbaric chamber are connected in proper order, and the spool in the hyperbaric chamber is with a buffering filtrating equipment outward.

Described buffering filtrating equipment is the pneumatic filter that matches with the hyperbaric chamber geomery.

The cup-shaped body of described filter.

The beneficial effects of the utility model are: be provided with pneumatic filter in the hyperbaric chamber of the utility model gas pressure reducer, the direct impact air filter of pressurized gas during work, reduced speed, can directly not impact spool, can guarantee effectively that the indication of low pressure outlet passageway steady air current, pressure gauge is more accurate.In addition, because gas itself contains some impurity, after pneumatic filter filters, can avoid impurity to stop up each road gas channel again.

As preferably, the pneumatic filter of described buffering filtrating equipment for matching with the hyperbaric chamber geomery, cup-shaped body, easily manufactured.

Embodiment

Below be the utility model preferred embodiment, but therefore do not limit protection domain of the present utility model.

With reference to Fig. 1, Fig. 2, shown in Figure 3, a kind of gas pressure reducer, comprise decompressor body 1, out splice going splice 2, input adapter 5, decompressor body 1 is provided with high pressure admission passage 1.1, hyperbaric chamber 1.2, low pressure chamber 1.3 and low pressure outlet passageway 1.4, is provided with the spool 7 that can control hyperbaric chamber 1.2 and low pressure chamber 1.3 disconnections or UNICOM in the hyperbaric chamber 1.2; Described out splice going splice 2, low pressure outlet passageway 1.4 and low pressure chamber 1.3 orders are connected, and input adapter 5, high pressure admission passage 1.2 and hyperbaric chamber 1.2 orders are connected, the spool 7 outer buffering filtrating equipments that are with in hyperbaric chamber 1.2.

Described buffering filtrating equipment is the pneumatic filter 6 that matches with hyperbaric chamber 1.2 geomeries.This pneumatic filter 6 cup-shaped bodies.In conjunction with shown in Figure 3.

The utility model structure is identical with the gas pressure reducer structure of prior art, unique different pneumatic filters 6 that are provided with in the hyperbaric chamber 1.2 of decompressor body 1 exactly.Pneumatic filter 6 can be the string bag of band copper mesh, perhaps for only allowing gas to pass through, and can reduce the device of gas velocity.

Working principle of the present utility model is: in conjunction with shown in Figure 1, the decompressor body 1 of the utility model gas pressure reducer is provided with high pressure admission passage 1.1 and low pressure outlet passageway 1.4, between decompressor body 1 and the diaphragm unit 11 hyperbaric chamber 1.2 and low pressure chamber 1.3, high pressure admission passage 1.1 is connected with hyperbaric chamber 1.2, and low pressure outlet passageway 1.4 is connected with low pressure chamber 1.3; Be provided with the spool 7 that to control hyperbaric chamber 1.2 and low pressure chamber 1.3 disconnections or UNICOM in the hyperbaric chamber 1.2.Input adapter 5 is connected with high pressure admission passage 1.2, and gas enters hyperbaric chamber 1.2 from high pressure admission passage 1.1 from the pressurized gas that gas cylinder comes out then through input adapter 5; Spool 7 is blocked by pneumatic filter 6, gas enters hyperbaric chamber 1.2 meeting impact air filter 6 before from high pressure admission passage 1.1, pneumatic filter 6 has reduced the flow velocity of gas, impurity screening, afterwards, gas enters hyperbaric chamber 1.2 and flows through and be depressurized behind the valve assembly 8, this moment gas flow rate slowly, stable, spool 7 is not had too big impact.The size of exit gas pressure is to regulate by adjusting handle assembly 10 compression adjustment springs 9; When the gas in the gas cylinder by the gas pressurized device and when having set up atmospheric pressure, the reading of pressure can show from pressure gauge 12, valve assembly 8 and spool 7 are in state of equilibrium; Low pressure chamber 1.4 is connected with low pressure outlet passageway 1.4, and low pressure outlet passageway 1.4 is connecting out splice going splice 2, and out splice going splice 2 connects hose couplings 4, and by output nut 3 both is screwed connection.Hose coupling 4 connects flexible pipe one end, and the flexible pipe the other end connects welding gun.
