The purpose of this utility model is in order to solve the deficiency of above-mentioned prior art, provide a kind of good seal performance, decompression performance good, bear pressure by force, the pressure bottle decompressor of fragile gas leakage not.
For achieving the goal, the utility model provides such technical solution: a kind of pressure bottle decompressor, it is characterized in that: this device is provided with a vent valve, be provided with vent rod between the suction port of vent valve and the pressure bottle bottle air outlet, the axial end of vent valve is connected with the jig that is used for fixing vent valve and pressure bottle bottle head, and the axial the other end of vent valve is threaded and connects the gas pressure controlling device that forms in proper order by piston, pressure spring and adjusting screw rod; Be divided into hyperbaric chamber and low-pressure cavity by venting channels in the vent valve, be provided with spring in the hyperbaric chamber, spring one end and vent rod offset, the spring the other end is connected with and is located near the washer of venting channels, be provided with to bar between washer and the piston, support venting channels connection washer and piston that bar passes vent valve, have the air outlet on the vent valve low-pressure cavity.
Feature of the present utility model is that also described jig is two arc wafer type jigs, and the mounting board dop is scheduled on the hollow sleeve clamping, and its rear portion is that screw rod connects, and on the screw rod mounting board the inner is being provided with the screw rod dop.
Feature of the present utility model also is described and vent rod is threaded with hollow sleeve, and vent rod and the spring end that offsets is a concave structure, and spring is butted in the groove.
Feature of the present utility model is that also the hyperbaric chamber of described vent valve is communicated with high pressure gauge outward, and the low-pressure cavity of vent valve is communicated with low-pressure meter and safety valve outward.
Feature of the present utility model also is the passway of described washer greater than passage.
It is that nut is connected to bar with piston that feature of the present utility model also is described, is provided with diaphragm between piston and the nut.
The utility model compared with the prior art, what the pressure bottle decompressor adopted is that direct current current-carrying formula valve body connects, therefore easy to adjust stable; Because connecting jig is the arc wafer type, screw rod compresses, thereby is connected firmly, not fragile cylinder valve; And adopt the gas spring sealing in the vent valve, and sealing effect is strengthened, be difficult for gas leakage, decompression is stable; Because pressure regulator adopts piston, diaphragm and screw rod to regulate, and therefore can bear than strong pressure, decompression property is good.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
In the accompanying drawing, on the pressure bottle decompressor of oxygen cylinder or acetylene cylinder, be provided with a vent valve 14, between the suction port of vent valve 14 and the pressure bottle bottle air outlet is vent rod 3, vent valve 14 axial ends are connected with the two arc wafer type jigs 2 that are used for fixing vent valve 14 and pressure bottle bottle head, the mounting board dop is scheduled on the hollow sleeve 19 clamping, its rear portion is that screw rod connects, and on the screw rod 1 mounting board the inner is being provided with screw rod dop 20, and vent rod 3 is threaded with hollow sleeve 19.The vent valve 14 axial the other ends are threaded and connect the gas pressure controlling device that forms by piston 10, pressure spring 11 and adjusting screw rod 12 orders; Be divided into hyperbaric chamber 15 and low-pressure cavity 16 by venting channels 13 in the vent valve 14, be provided with spring 4 in the hyperbaric chamber 15, spring 4 one ends and vent rod 3 offset, and vent rod 3 and spring 4 end that offsets is a concave structure, and spring 4 is butted in the groove; Spring 4 the other ends are connected with near the washer 7 that is located at the venting channels 13, and washer 7 is greater than the passway of passage 13.Have to bar 17 between washer 7 and the piston 10, support the venting channels 13 connection washers 7 and piston 10 that bar 17 passes vent valve 14, support bar 17 and be connected, be provided with diaphragm 8 between piston and the nut with piston 10 nuts.Have air outlet 18 and low-pressure meter 6 and safety valve 9 on vent valve 14 low-pressure cavity; The hyperbaric chamber 15 outer high pressure gauges 5 that are communicated with of vent valve 14.
During use, earlier vent rod 3 is passed hollow sleeve 19 and offset with spring 4 in the vent valve 14, again arc wafer type jig 2 is enclosed within the pressure bottle bottle head of oxygen cylinder or acetylene cylinder, the suction port of vent rod 3 is aimed at the pressure bottle air outlet, regulate clamping screw 1, make withstand pressure platform on the cylinder valve of the screw rod dop of screw rod 1, and make arc wafer type jig 2, vent valve 14 fixing in aggregates.Open the pressure bottle bottle valve, make gas enter hyperbaric chamber 15, because the washer effect, gas can't be discharged, at this moment, adjust adjusting screw rod 12, compression piston 10 makes spring 4 compressions by compress washer 7 to bar 17, thereby regulates the air pressure in the hyperbaric chamber 15, so can discharge by air outlet 18 by observing the gas that low-pressure meter 6 adjusts required pressure.
What the utility model adopted is that direct current current-carrying formula valve body connects, therefore easy to adjust stable; Because connecting jig is the arc wafer type, screw rod compresses, thereby is connected firmly, not fragile cylinder valve; And adopt the gas spring sealing in the vent valve, and sealing effect is strengthened, be difficult for gas leakage, decompression is stable; Because pressure regulator adopts piston, diaphragm and screw rod to regulate, and therefore can bear than strong pressure, decompression property is good.
