Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
As shown in Figure 1, the device that the present invention is reduced pressure to gas, it comprises an air input joint 1, one main body 2 and an air outlet adapter 3, air input joint 1 is for being connected with the steel cylinder storing pressurized gas, air outlet adapter 3 is for being connected with using the welding gun of low-pressure gas, main body 2 is provided with a reduction valve 4 and flow meters 5, flowmeter 5 comprises a transparent outer tube 502 and and is arranged at transparent interior pipe 501 in this transparent outer tube 502, transparent outer tube 502 and transparent interior pipe 501 are all vertically arranged, transparent outer tube 502 and transparent interior pipe 501 are made by transparent plastic, the sidewall of transparent outer tube 502 is provided with dial 5021, dial 5021 extends along the axial direction of transparent outer tube 502, a steel ball 503 is provided with in transparent interior pipe 501, steel ball 503 can move freely along the axial direction of transparent interior pipe 501.
The top of the sidewall of transparent interior pipe 501 is provided with the breach 504 being communicated with transparent interior pipe 501 and transparent outer tube 502, described breach 504 has two and is arranged at the both sides of transparent interior pipe 501, be provided with the inlet communication of air input joint 1 with reduction valve 4 in main body 2, the bottom of the outlet of reduction valve 4 with transparent interior pipe 501 is communicated with, by the passage that transparent outer tube 502 is communicated with air outlet adapter 3, after air input joint 1 is connected with the steel cylinder storing pressurized gas, pressurized gas enter main body 2 from air input joint 1, then pressurized gas flow to reduction valve 4 by passage, pressurized gas are become low-pressure gas by reduction valve 4, then low-pressure gas flows to the bottom of transparent interior pipe 501 by passage, low-pressure gas enters transparent interior pipe 501 and upwards flows, now low-pressure gas blows steel ball 503 and moves up, can the position of steel ball 503 be read by dial 5021 and learn the flow of low-pressure gas, then the low-pressure gas in transparent interior pipe 501 flows out transparent interior pipe 501 by breach 504, low-pressure gas flows down in main body 2 along transparent outer tube 502 after flowing out transparent interior pipe 501, then low-pressure gas flows to air outlet adapter 3 by passage, air outlet adapter 3 connects welding gun can weld.
As shown in Figure 2, the open-topped of described transparent interior pipe 501, the top of transparent outer tube 502 closes, that is the top of transparent outer tube 502 is a roof 505, roof 505 is in aggregates with transparent outer tube 502, between the top that one cushion pad 506 is arranged on transparent interior pipe 501 and roof 505, one surface coverage of one cushion pad 506 is on the top of transparent interior pipe 501, another surface of cushion pad 506 offsets with roof 505, that is between cushion pad 506 top that is clamped and fixed in transparent interior pipe 501 and the roof 505 of transparent outer tube 502, roof 505 is provided with thin region 507, cushion pad 506 is provided with the through hole 5061 extending to thin region 507 in transparent interior pipe 501, also just say that the low-pressure gas in transparent interior pipe 501 can flow to thin region 507 by through hole 5061.
Described cushion pad 506 with between roof 505, all bonding by sealer between cushion pad 506 with the top of transparent interior pipe 501, like this, gas in through hole 5061 can be avoided from the slot leakage between cushion pad 506 and roof 505, once the gas in through hole 5061 is from the slot leakage between cushion pad 506 and roof 505, the air pressure in through hole 5061 will be made to reduce and thin region 507 cannot be broken through in time, the risk of whole flowmeter 5 blast will be increased, and sealer is set between cushion pad 506 and roof 505, can effectively avoid this risk.
Described transparent interior pipe 501 and the wall thickness of transparent outer tube 502 are 2mm, and the wall thickness in described thin region 507 is 0.6mm.
Component and the parts by weight of described transparent outer tube 502 and transparent interior pipe 501 are: transparent resin 100 parts, heat stabilizer 2 parts, light stabilizer 2 parts, 50 parts, glass fibre, antioxidant 2 parts, whisker 1 part, nucleator 1 part.
The perisporium of described transparent outer tube 502 is embedded with the steel traveler 6 of multiple annular, each steel traveler 6 all extends along the circumferential direction of transparent outer tube 502, multiple steel traveler 6 distributes along the axial direction uniform intervals of transparent outer tube 502, the intensity of transparent outer tube 502 is increased, avoids transparent outer tube 502 to explode owing to passing into pressurized gas further.
The pressure maximum that the pressure maximum that the thin region 507 of transparent outer tube 502 can bear can bear than other parts of transparent outer tube 502 is little, like this, when reduction valve 4 lost efficacy and made pressurized gas directly enter transparent interior pipe 501, air pressure in transparent interior pipe 501 raises gradually, and the gas in transparent interior pipe 501 flow to thin region 507 by through hole 5061 and applies pressure to thin region 507, when the air pressure in transparent interior pipe 501 is elevated to the pressure maximum that thin region 507 can bear, just break in thin region 507, and after thin region 507 breaks, roof 505 will be easy to stress deformation and break, so after breaking in thin region 507, cushion pad 506 will owing to being subject to the active force of the gas in transparent interior pipe 501 and breaking through the roof 505 of transparent outer tube 502, the top of transparent outer tube 502 is made to break like this, gas flows out from the top of transparent outer tube 502, air pressure in flowmeter just reduces, avoid flowmeter blast, and due to when the device using this to reduce pressure to gas, flowmeter vertically arranges, like this, the roof 505 of cushion pad 506 and transparent outer tube 502 arranges and arranges upward, when breaking in thin region 507 and when cushion pad 506 breaks through the roof 505 of transparent outer tube 502, cushion pad 506 and the fragment produced will upwards launch, fragment can not splash towards periphery, can avoid damaging the staff of surrounding and machinery equipment.
Below only apply preferably example with regard to the present invention and made explanation, but can not be interpreted as it is limitations on claims, structure of the present invention can have other to change, and is not limited to said structure.In a word, all various changes done in the protection domain of independent claims of the present invention are all in protection scope of the present invention.
