Abstract
The utility model relates to an inflation valve, in particular to a high-air-impermeability inflation valve. The high-air-impermeability inflation valve mainly solves the technical problem that an inflation valve in the prior art is complex in structure, high in manufacturing cost, poor in sealing effect, low in inflation efficiency and the like. The high-air-impermeability inflation valve comprises an inflation valve base (1) and is characterized in that an inflation-valve valve element (2) is arranged inside the inflation valve base (1), an inflation-valve valve deck (3) is arranged outside the inflation-valve valve element (2), a sealing cover (4) is arranged at the upper end of the inflation-valve valve element (2) in a sealed mode, an inflation valve sealing plug (5) is arranged inside the inflation-valve valve element (2), an inflation valve spring (6) is arranged between the position below the inflation valve sealing plug (5) and the inflation valve base (1), and an inwards-protruding sealing protruding ring (7) is arranged at the position where the inflation-valve valve element (2) is in contact with the inflation valve sealing plug (5).
Description
Technical field
The utility model relates to a kind of gas charging valve, especially relates to a kind of high-air-tightness gas charging valve.
Background technique
At present, in transportation process, maximum goods damage factor is the collision between goods forward or backward and cause packages in damaged condition, and then causes the infringement of goods.In order to address this problem, conventionally by wooden rack or foamed plastics etc., fill the gap between goods.But these materials all can not be satisfactory in cost and protection effect, and be subject to many limitations, and along with the raising day by day of environmental requirement, wooden/packing materials such as foamed plastics are given up.So people just use air bag instead; air bag can effectively prevent at truck; the movement of goods in shipping container or railway transport; it fully fills the space between goods; supporting goods is because rocking the quality producing, and absorbing vibration, protects goods to avoid damaging in transit; than any other support, fill protection better effects if, than with more environmental protection of traditional filling mode such as foamed plastics.Chinese patent discloses a kind of gas charging valve (notice of authorization number: CN 202597808 U), it comprises housing, in housing, be provided with cavity, first and second pipe joint that on housing, setting is connected with the supply air line of gas holder and motor, cavity is communicated with the tube chamber of first and second pipe joint, one-way valve is set in cavity, and the exhaust end of one-way valve is positioned at cavity, and the gas fill port that the air inlet end of one-way valve is offered with housing is connected; First and second pipe joint is that the two ends of a body form, the through hole of offering on the sidewall of body middle part forms gas fill port, one-way valve is fixed in through hole, the side of body is also provided with the connecting tube being connected with its connection, the tube chamber of body and connecting tube constitutes cavity, connecting tube outer end is provided with the end cap being sealed and matched with it, is provided with the obstruction unit that one-way valve exhaust end is stopped up in cavity.But the structure of this gas charging valve is comparatively complicated, and manufacture cost is higher, and sealing effect is poor, and charging efficiency is lower.
Model utility content
The utility model is to provide a kind of high-air-tightness gas charging valve, and it is mainly that to solve the structure of the existing gas charging valve of prior art comparatively complicated, and manufacture cost is higher, and sealing effect is poor, the technical problem of the lower grade of charging efficiency.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of high-air-tightness gas charging valve of the present utility model, comprise air valve base, in described air valve base, be provided with air valve core, air valve core is provided with air valve valve gap outward, air valve core upper end is sealed with capping, in air valve core, be provided with air valve sealing plug, between air valve sealing plug below and air valve base, be provided with spring for valve, air valve core and air valve sealing plug contacting point are provided with to projecting inward sealing bulge loop.Gas charging valve is comprised of air valve base, air valve valve gap, air valve core and spring for valve; Air valve core Nei You bis-roads sealings: 1. by additional spring-force driven dual in air valve sealing plug, make air valve sealing plug block the lumen orifice of valve, guarantee tightness; The part that contacts with air valve sealing plug at air valve core, has creatively designed a sealing bulge loop simultaneously, makes in working order to seal bulge loop and is firmly attached at air valve sealing beyond the Great Wall, reaches 100% of sealability; 2. after inflator completes, capping is filled in to gas charging valve lumen orifice, carry out seal spool for the second time.
As preferably, the external diameter of described air valve core is provided with the conical surface, and conical surface contact air valve valve seat while making spool pack valve seat into, seals as bottle stopper.
As preferably, the outer surface of described air valve core is provided with the O shape circle that integral type is made.When assembling, when air valve valve gap covers compression, make the O shape on air valve core enclose the airtight effect outside blanket gas valve core, improve sealing effect.
As preferably, described capping is connected with draw ring, can easily capping be pulled open.
Therefore, the utlity model has high leak tightness, aeration speed is fast, strengthen the lumen pore size of air valve core and increase airslide, guaranteeing draft speed, can guarantee again the guiding (assurance sealing effect) of air valve sealing plug, the tape guide function of air valve sealing plug own, and inside is provided with spring for valve; Avoid existing gas charging valve on market only by self back pressure after inflation, to seal that (dwell time is not long, stability is not high), air valve base bottom is staggered support arm, except not hindering inflation air inlet, also for spring for valve provides support a little, though make air valve exquisiter.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering in figure: air valve base 1, air valve core 2, air valve valve gap 3, capping 4, air valve sealing plug 5, spring for valve 6, sealing bulge loop 7, the conical surface 8, O shape circle 9, draw ring 10.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of high-air-tightness gas charging valve of this example, as Fig. 1, comprise air valve base 1, in air valve base, be provided with air valve core 2, air valve core is provided with air valve valve gap 3 outward, and air valve core upper end is sealed with capping 4, and capping is connected with draw ring 10.In air valve core, be provided with air valve sealing plug 5, between air valve sealing plug below and air valve base, be provided with spring for valve 6, air valve core and air valve sealing plug contacting point are provided with to projecting inward sealing bulge loop 7.The external diameter of air valve core is provided with the conical surface 8, conical surface contact air valve valve seat.The outer surface of air valve core is provided with the O shape circle 9 that integral type is made.
During use, utilize draw ring 10 to unplug capping 4, charge gun mouth stuffed is entered to gas charging valve lumen orifice, due to gas pressure, air-flow is pushed air valve sealing plug 5 open, and the airslide of flowing through on spool is inflated air bag, after inflation, extract charge gun, air valve sealing plug 5 is again blocked gas charging valve lumen orifice under spring for valve 6 effects, plays seal action; Capping 4 is filled in to air-filled pore, again sealing.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
