Abstract
The utility model relates to a valve inside trade, especially liquid gas use aerifys the valve inside. The utility model relates to a novel valve inside comprises connector, air cock, sealing washer, spring, gas -supply pipe, and connector and gas -supply pipe fixed connection, air cock are fixed in connector and gas -supply pipe by the spring in the middle of, the air vent of air cock is by the sealing washer shutoff, and its main points lie in division having the spout hole in the side of connector, and the position that the spout hole was located is not higher than the sealing washer. The utility model discloses small, simple structure can effectively improve gas cylinder inflating volume, thoroughly solve because of the gasification space is not enough in the gas cylinder, atmospheric pressure is high, and the liquid gas blowout results in phenomenons such as the recoil is not enough, gaseous waste increase pulling the trigger occasionally.
Description
Technical field
The utility model patent relates to valve inside industry, the pumping valve inside of especially liquid gas use.
Background technique
Existing valve inside as shown in Figure 1, be made up of connecting body 9, valve 7, seal ring 8, spring 6, pneumatic tube 5, connecting body 9 is fixedly connected with pneumatic tube 5, valve 7 is fixed in the middle of connecting body 9 and pneumatic tube 5 by spring 6, the vent 71 of valve 7 is by seal ring 8 shutoff, vent is positioned at the lower limb of valve and seal ring contact position, is side direction aperture, and normal condition seal ring sealing ventilation hole gas can not leak.During inflation, valve moves down, bear certain gas pressure, although valve groove cannot be departed from, but overall past groove top edge moves, now vent normal connection with gas cylinder internal does not intercept by seal ring, treat that inflation completes, spring-force driven dual valve moves until be fitted and connected body, now seal ring is arranged in valve groove position seals vent on the lower side.As shown in Figure 2, it is inflating gas cylinder that valve inside is contained in gas cylinder, gas cylinder is by gas cylinder lid 2, bottle 1 forms, suction tude 21 is had in gas cylinder lid 2, valve inside is fixed in suction tude 21 by connecting body 9 by screw thread, the other end of bottle 1 is designed with gas outlet valve 4, when using valve inside to inflating gas cylinder, external inflation capital is calmed the anger mouth 7, spring 6 is compressed, valve 7 moves in gas cylinder, vent 71 departs from seal ring 8 and enters pneumatic tube 5, outside liquid gas enters gas cylinder, because the gas outlet valve 4 of now gas cylinder is in closed condition, gas in gas cylinder is compressed, until the pressure in gas cylinder stops inflating after balancing with outside liquid gas pressure, gasification space 11 size now in gas cylinder is uncertain, pressure is large, when gas cylinder installs in air pistol, (in figure, turnback is revolved in gas cylinder position) gasification space 11 is in the below of gas outlet valve 4, the use initial stage due to the air pressure in gasification space 11 large, valve 4 of giving vent to anger is opened rear pressurized gas and is flowed out fast, the liquid gas be not gasified totally is taken out of, the range of impact shooting, the liquid gas simultaneously the sprayed heat that vaporization absorption is a large amount of in gas hand, in air pistol, temperature extremely drops under the lower limit of air pistol internal rubber seal circle normal working temperature, have a strong impact on follow-up fire.
Summary of the invention
The purpose of this utility model is that overcoming existing valve inside exists shortcoming, there is provided that a kind of aeration quantity is stable, gasification space size, pressure controllable in gas cylinder, and after effectively solving the less or valve open of giving vent to anger of liquid gas content in container, flow out the Novel valve inside of the problems such as the liquid gas be not gasified totally.
The technological scheme that the utility model adopts is a kind of Novel valve inside, be made up of connecting body, valve, seal ring, spring, pneumatic tube, connecting body is fixedly connected with pneumatic tube, valve is fixed in the middle of connecting body and pneumatic tube by spring, the vent of valve is by seal ring shutoff, its main points are to have overflow hole in the side of connecting body, and the position residing for overflow hole is not higher than seal ring.
The utility model improves on existing valve inside basis, connecting body adds overflow hole, during inflation, Aerating needle withstands valve, and then Compress Spring, the vent of valve departs from seal ring and enters pneumatic tube, outside liquid gas enters gas cylinder, valve and seal ring move down simultaneously and make seal ring cross the overflow hole of connecting body side, now liquid gas to flow in container and by the air in container by outside overflow hole amount discharge container, container is full of fast, when the cylindrical hole lower end surface that the liquid level gas cylinder lid of liquid gas in container is outstanding, liquid gas can along cylindrical hole upwards and flowed out by the overflow hole of connecting body side, prompting container is to be full of, now stop inflation, valve under spring force on move and be with on dynamic seal ring and move, the overflow hole of connecting body side crossed by seal ring, by container closure.The part being now in more than gas cylinder lid cylindrical portion lower end surface in container does not have liquid gas, just can maintain suitable gasification space like this during venting.
Overflow hole is arranged in the shift motion of seal ring, valve, seal ring not pressurized time, the position residing for overflow hole is not higher than seal ring, and when valve, seal ring move to bottom, overflow hole is positioned at the top of seal ring.This can ensure that overflow hole is no longer in communication with the outside after inflation terminates.
The utility model volume is little, structure simple, effectively can improve gas cylinder dress tolerance, thoroughly solves because gasification space in gas cylinder is not enough, air pressure is high, has liquid gas to spray cause the phenomenons such as recoil deficiency, the increase of air-loss amount when pulling the trigger.
