Abstract
The utility model discloses a corrugated metal diaphragm gas pressure reducer which comprises a gas pressure reducer main body (1), a corrugated metal diaphragm (2), a cover (3), a large spring (4), a stable spring retainer (5), a cap nut (6), a handle (7), a nut (8), an adjusting rod (9), a spring retainer (10), an integrated valve core (11), a filtering plug (12), a suction nozzle (13), a safety valve (14), a venting nozzle (15), a low pressure gauge head (16), a high pressure gauge head (17), a large nut (18), a handle cover (19), a flange (20) and a corrugation (21). The corrugated metal diaphragm gas pressure reducer is characterized in that the corrugated metal diaphragm (2) is circular, and the edge of the corrugated metal diaphragm (2) is provided with the flange (20) turning up towards one side and is spread outwards to form the corrugation from the centre of a circle. The flange (20) at the edge of the corrugated metal diaphragm (2) is putted at a tight connection place between the gas pressure reducer main body (1) and the cover (3). When the gas pressure reducer is in use, tension stress is reduced due to the corrugated shape on the corrugated metal diaphragm (2), so that the pressure reducer is stable in pressure and flow, and is high in precision when being in the working state.
Description
Technical field
The utility model relates to a kind of gas pressure reducer, relates in particular to a kind of corrugated metal diaphragm gas pressure reducer.
Background technique
Gas pressure reducer is to the bottled gas of high pressure and the pipeline high-pressure air feed reduces pressure and the controlling device of flow control.Along with the reach of science, gas pressure reducer is widely used in the analytical instrument industry, puts distribution industry, environmental protection industry (epi), medical industry, power industry, petroleum chemical industry, semicon industry etc.The diaphragm that present gas pressure reducer is selected for use has following two kinds:
1, elastomer diaphragm gas pressure reducer: because rubber membrane sector-meeting severe contamination high-purity gas, the testing precision of lowering apparatus, directly have influence on the quality of product of semiconductor components and devices, so can not be used for the analytical instrument industry, put distribution industry, environmental protection industry (epi), medical industry, power industry, petroleum chemical industry, semicon industry and high-purity gas.
2, metal diaphragm gas pressure reducer: be widely used in the analytical instrument industry at present, put on distribution industry, environmental protection industry (epi), medical industry, power industry, petroleum chemical industry, semicon industry and the high-purity gas.But the anti-stress of metal diaphragm is big, can not reach the pressure and the flow that need accurate control.
The model utility content
Problem to be solved in the utility model is to overcome above defective, provides a kind of simple in structure, and reliable performance is economical and practical, can precise pressure control and the corrugated metal diaphragm decompressor of flow.
The corrugated metal diaphragm gas pressure reducer of the utility model comprises gas pressure reducer main body (1), corrugated metal diaphragm (2), lid (3), big spring (4), steady spring abutment (5), cap nut (6), handle (7), nut (8), adjustable lever (9), spring abutment (10), integrated type spool (11), filtering plug (12), air inlet nozzle (13), safety valve (14), outlet nozzle (15), low pressure gauge outfit (16), high pressure gauge outfit (17), big nut (18), handle cover (19), flange (20), ripple (21).The corrugated metal diaphragm of its feature (2) is circular, and ripple is outwards expanded to a side flanging (20) in the edge from the center of circle.The flange (20) at corrugated metal diaphragm (2) edge is placed on gas pressure reducer main body (1) and the tight joint of lid (3).
The corrugated metal diaphragm gas pressure reducer of the utility model, corrugated metal diaphragm is selected the 316L stainless steel material for use, neither pollutes high-purity gas, and is corrosion-resistant, can reach the effect of the voltage stabilization and current stabilization of precision again.
Description of drawings
Below in conjunction with accompanying drawing concrete mode of the present utility model is done a detailed description.
Fig. 1 is the structural representation of existing corrugated metal diaphragm gas pressure reducer;
Fig. 2 is the profile schematic representation of existing corrugated metal diaphragm gas pressure reducer;
Fig. 3 is the corrugated metal diaphragm schematic representation of existing corrugated metal diaphragm gas pressure reducer;
Among the figure: 1, gas pressure reducer main body 2, corrugated metal diaphragm 3, lid 4, big spring 5, steady spring abutment 6, cap nut 7, handle 8, nut 9, adjustable lever 10, spring abutment 11, integrated type spool 12, filtering plug 13, air inlet nozzle 14, safety valve 15, outlet nozzle 16, low pressure gauge outfit 17, high pressure gauge outfit 18, big nut 19, handle cover 20, flange 21, ripple
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, be structural representation, profile schematic representation, the corrugated metal diaphragm schematic representation of corrugated metal diaphragm gas pressure reducer in the prior art.Corrugated metal diaphragm gas pressure reducer is when work, gas enters gas pressure reducer main body (1) by air inlet nozzle (13) and filtering plug (12) earlier, enter the low pressure chamber of gas pressure reducer again by integrated type spool (11), obtain source of the gas by corrugated metal diaphragm (2), big spring (4), steady spring abutment (5), adjustable lever (9), the handle (7) that is provided with.Corrugated metal diaphragm (2) is circular, the edge is to a side flanging (20), outwards expand ripple from the center of circle, the flange (20) at corrugated metal diaphragm (2) edge is placed on gas pressure reducer main body (1) and the tight joint of lid (3), corrugated metal diaphragm is made for the 316L stainless steel material, corrosion-resistant, do not pollute high-purity gas, can also the accurate source of the gas of controlling voltage stabilization and current stabilization.
Embodiment is: at first high pressure gauge outfit (17), low pressure gauge outfit (16), safety valve (14), air inlet nozzle (13), outlet nozzle (15), integrated type spool (11) are screwed and be connected on the gas pressure reducer main body (1), again corrugated metal diaphragm (2) card is placed on gas pressure reducer main body (1) upper end, pack in order then big spring (4), steady spring abutment (7), adjustable lever (9) is screwed into lid (3) upper end, joining with lid (3) and gas pressure reducer main body (1) screws again, and loads onto handle (7) in the upper end of adjustable lever (9) at last.The air inlet nozzle (13) of integrated type spool gas pressure reducer is connected with gas cylinder (gas path pipe) during use, and outlet nozzle (15) is connected with the instrument that uses, and regulates obtaining needed gas pressure and flow by handle (7).Because the ripple struction that corrugated metal diaphragm (2) is unique can significantly reduce the anti-stress of diaphragm to gas, can reach the effect of the voltage stabilization and current stabilization of precision.And corrugated metal diaphragm is made for the 316L stainless steel material, and is both corrosion-resistant, do not pollute high-purity gas again.Corrugated in addition metal diaphragm gas pressure reducer is provided with safety valve (14), and when using gases pressure surpassed 1.3 times of rated pressure, safety valve (14) is exhausting air automatically, has guaranteed user's safety.
