Abstract

The utility model provides a withstand voltage pair of courage inert gas protection jar for oxyhydrogen generator is last, includes outer courage, inner bag, one -way check valve and sealing member. The vexed head of inner bag at inner bag both ends all welded external blow vent, the inner bag embolias in the outer courage to become even space between adjustment inner bag and the outer courage, it is vexed overhead that the outer courage at courage both ends is worn to adorn outside respectively through the vexed overhead external blow vent of its both ends inner bag to the inner bag, and weld vexed overheadly at the outer courage at both ends. One -way check valve through the welding of its shell on outer courage and inner bag space UNICOM between the courage outside with, the space injection inert gas between to inner bag and outer courage protects through one -way check valve. The utility model discloses the advantage: the sealing performance of inner bag has been increased, because the high pressure of inside and outside courage is poor, can make the compressive property of inner bag get a promotion, obtains the better final effect of sealed resistance to compression.

Description

A kind of pressure pair of gallbladder inert gas shielding tank on oxyhydrogen generator

Technical field

This utility model patent relates to chemical industry spherical tank manufacturing technology, particularly relates to a kind of pressure pair of gallbladder inert gas shielding tank on oxyhydrogen generator.

Background technology

It is to use corrosion resistant plate to make inner bag and outer gallbladder through argon arc welding mostly that oxyhydrogen water separation tank manufactured by oxyhydrogen generator equipment, gas storage tank, high pressure resistant anti-backfire fill, the tank body that inner bag is formed is for storing hydrogen and oxygen gas mixture produced by oxyhydrogen generator, produced by oxyhydrogen generator, its mixing ratio of hydrogen and oxygen gas mixture itself is hydrogen 2: oxygen 1, and its mixed gas has self flammable, explosiveness.Therefore.This kind of gas is stored and the explosion-proof task of top priority being to manufacture this kind of equipment safety, in the past, the air accumulator produced was the stainless cylinder of steel of monolayer, and the atomic radius of hydrogen is the least, tank body can be caused to produce fraction of leakage phenomenon, greatly reduce the safety of equipment.

Utility model content

The technical problems to be solved in the utility model is to provide one and has excellent sealing resistance to compression effect, the pressure pair of gallbladder inert gas shielding tank on oxyhydrogen generator of safety.

The technical scheme is that

A kind of pressure pair of gallbladder inert gas shielding tank on oxyhydrogen generator, including outer gallbladder, inner bag, inlet non return check valve and sealing member.The inner bag at the upper and lower two ends of described inner bag is silently respectively welded external gas outlet and air inlet, described inner bag is inserted in outer gallbladder, and adjust between inner bag and outer gallbladder uniformly space, external gas outlet that inner bag is silently gone up by its two ends inner bag and air inlet are installed on the outer gallbladder at outer gallbladder two ends respectively and silently go up, and the outer gallbladder being welded on two ends is silently gone up.Described inlet non return check valve is welded on outer gallbladder the space UNICOM also and between inner bag and outer gallbladder by its shell, injects inert gas shielding by inlet non return check valve to the space between inner bag and outer gallbladder.

Above-mentioned sealing member seals in screwing in inlet non return check valve.

Above-mentioned outer gallbladder is provided with pressure sensor interface, can be by outer gallbladder, the instant pressure sensing of noble gas is to control system, and when in outer gallbladder, inert gas pressure drops to less than inner bag gas pressure, system is by autostop and sends alarm.

This utility model is to utilize to add again one layer of outer gallbladder in the outside of former tank body; inlet non return check valve is disposed outside on gallbladder; and the space between inner-outer tube; inject noble gas; its pressure requirements of noble gas being injected into this space is significantly larger than the hydrogen or oxygen gas pressure stored by inner bag; due to the radius of the atomic radius of noble gas hydrogen atoms to be several times as much as, one layer of inert gas shielding therefore can be increased again in the outside of inner bag, advantage of the present utility model:

1, the sealing property of inner bag is added；

2, due to the High Pressure Difference of inner-outer tube, the compressive property of inner bag can be made to get a promotion, it is thus achieved that preferably to seal resistance to compression final effect.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model patent.

Detailed description of the invention

A kind of pressure pair of gallbladder inert gas shielding tank on oxyhydrogen generator, including outer gallbladder 2, inner bag 1, inlet non return check valve 5 and sealing member 4.Described outer gallbladder 2 and inner bag 1 all use corrosion resistant plate to be welded through argon arc welding, the inner bag at described inner bag about 1 two ends silently 6 is respectively welded external gas outlet 8 and air inlet 10, described outer gallbladder 2 is welded with inlet non return check valve 5 in advance, inner bag 1 be inserted in only be welded with gallbladder outside one end silently 7 outer gallbladder 2 in, and adjust between inner bag and outer gallbladder uniformly space, the outer gallbladder of the other end is welded again silently after adjustment, inner bag 1 is respectively mounted the outer gallbladder at gallbladder 2 two ends outside silently on 7 by the external gas outlet 8 on its two ends inner bag silently 6 and air inlet 10, and it is welded on the outer gallbladder at two ends silently on 7.Described inlet non return check valve 5 is welded on outer gallbladder 2 the space UNICOM also and between inner bag and outer gallbladder by its shell.Described inner bag to carry out testing pressure after welding, pressure measurement must not be less than 1.2Mpa, and the pressure measurement time must not be less than 24 hours, and pressure drop cannot be greater than 0.015 Mpa.Outer gallbladder to carry out surveying pressure after welding, pressure measurement must not be less than 1.2Mpa, and the pressure measurement time must not be less than 24 hours, and pressure drop cannot be greater than 0.01Mpa.Double gallbladder air accumulators after manometric test inject noble gas 3 by inlet non return check valve to the space between inner bag and outer gallbladder and protect.The injection pressure of noble gas requires at 0.8 more than Mpa, then screws in sealing member 4 to inlet non return check valve 5.Additionally; outer gallbladder 2 is provided with pressure sensor interface 9; can be by the instant pressure sensing of noble gas in outer gallbladder to control system; when in outer gallbladder, inert gas pressure drops to less than inner bag gas pressure; system is by autostop and sends alarm, a kind of pressure pair of gallbladder inert gas shielding tank on oxyhydrogen generator of described composition.
