The Multifunction pressure-reducing valve of described single inflating gas cylinder mouth also comprises the gas cylinder joint 211 be located in air relief valve main body 2.This gas cylinder joint 211 is provided with screw thread and can is directly assemblied on gas cylinder.
Air relief valve of the present utility model, will be used for the inflation slide block 3 sealing inflatable interface 4, be applied to the sealing in air relief valve internal low-voltage chamber 205 simultaneously, filling channel 201 be arranged on the outside of air relief valve low pressure chamber, achieves the integrated of aerification function and decompression; Relief valve is arranged on inflation slide block 3 in addition, can leave more space mounting pressure transducers, Pressure gauge or alarm device etc. on reducing valve body, increases relief valve function and purposes.
Air relief valve of the present utility model, by air relief valve together with charge valve function i ntegration, employs the respiratory organ of this air relief valve, do not need when inflation to dismantle air relief valve again, directly the inflatable interface of air relief valve and source of the gas can be connected, directly inflate, convenient and swift, decrease unnecessary dismounting.
Two gas cylinder air relief valve operation principle is as follows:
As shown in Figure 6, the view of air relief valve when being inflation.
When gas cylinder needs to inflate, the interface of source of the gas is arranged on inflatable interface 4, start inflation, under the promotion of the gases at high pressure of source of the gas, pressure on the right side 301 of inflation slide block 3 is greater than the pressure on left side 303, and inflation slide block 3 is moved to the left, and the through hole 302 that gases at high pressure are arranged by inflation slide block 3 edge enters in air relief valve, then enter into the inflation aperture 201 that air relief valve main body 2 is arranged and enter into high pressure chest 202, then enter into gas cylinder through interface 203.
As shown in Figure 7, be the view of air relief valve when having inflated.
When inflating gas cylinder reaches requirement air pressure, close inflation source, under the effect of air relief valve air pressure inside, the end force of inflation slide block 3 left side 303 is greater than the end force of right side 301, and inflation slide block 3 moves to right, crush seal circle 6, make air relief valve inside airtight, can not leakage be produced, gas source interface be unloaded from inflatable interface 4, completes inflation.
Work process illustrates: as shown in Figure 8, Figure 9, view when being air relief valve work.
When low pressure chamber air pressure inside is nominal pressure, relief pressure valve cartridge about 1 two direction stress balance, relief pressure valve cartridge 1 left end seals the air inlet 204 of air relief valve main body 2, when low pressure chamber 205 air pressure inside is lower than nominal pressure, relief pressure valve cartridge 1 left end pressure is greater than right-hand member pressure, relief pressure valve cartridge 1 moves to right, gases at high pressure enter low pressure chamber 205, then the aperture 101 on relief pressure valve cartridge 1 enters the inner chamber of relief pressure valve cartridge 1, due to entering of gases at high pressure, the air pressure of low pressure chamber 205 and relief pressure valve cartridge inner chamber is increased, cause the increasing pressure on relief pressure valve cartridge end face 102 large, when air pressure increases above nominal pressure, pressure on end face 102 is greater than the pressure of air relief valve left end, relief pressure valve cartridge 1 moves to left, between high pressure chest 202 and low pressure chamber 205, passage is cut off, about the air pressure that ensure that in low pressure chamber 205 remains on nominal pressure.
Relief valve on inflation slide block 3 can regulate the air pressure in low pressure chamber.Low pressure chamber 205 air pressure inside is regulated by the balance of safe spool 9 both ends of the surface, by the decrement of emergency valve nut 10 regulation safety valve core spring 11, can control the pressure of safe spool 9 right-hand member.Low pressure chamber 205 internal gas pressure is too high, will produce the pressure that be greater than right side in safe spool left side, thus promotes safe spool 9 and move to right and carry out pressure release, makes air pressure drop to nominal pressure; When low pressure chamber 205 air pressure inside arrives nominal pressure, the active force of safe valve core spring 11 is greater than the pressure of safe spool 9 left end, and safe spool 9 moves to left, and seals low pressure chamber 205.
Gases at high pressure enter high pressure chest 202 from gas cylinder, are provided with filtration core 14 between high pressure chest 202 and air inlet 204, the gas entering low pressure chamber 205 inside are filtered totally, the safety ensured respiration.High pressure chest 202 is connected with interface 208, and interface 208, for installation high-voltage sensor, can detect the air pressure in gas cylinder, if air pressure is too high or too low all can report to the police (over voltage alarm during inflation, low pressure alarming during use); Low pressure chamber 205 is connected by interface 206 and breathing pipeline, and the air pressure in breathing pipeline, for installing low pressure sensor, can detect in interface 207 place.Each interface of air relief valve is installed by functional requirement, achieves the digitized of product, make the monitoring of air relief valve more convenient, quick, accurate, adopt the respiratory organ of this air relief valve can be safer.
As shown in Figure 10 and Figure 11, be single gas cylinder air relief valve.
Similar with two gas cylinder structure of relief pressure valve, lack a cylinder interface, this position is used for installation high-voltage sensor, front end is used for setting pressure table or alarm device, the advantage of this single gas cylinder air relief valve is: air relief valve is provided with inflatable interface 4, can not remove air relief valve directly to inflating gas cylinder; This air relief valve is provided with the screw thread 211 that can directly be assemblied on gas cylinder, this just can save cylinder valve, reduces cost.
The above; be only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
