Abstract
The utility model discloses a kind of air valve for vacuum sealer, including gas tube（57）, in gas tube（57）The uniform one group of muffler of outer circumference（61）, in gas tube（57）Side connect the first fixed plate（58）, opposite side connect the second fixed plate（62）, in the first fixed plate（58）Upper connection cylinder（59）, in cylinder（59）Piston rod on connect gland（60）, gland（60）It is arranged on gas tube（57）It is interior, in fixed plate（62）It is provided with centre bore（62.1）, gland（60）With centre bore（62.1）Corresponding matching.Advantage of the present utility model：The present apparatus is simple in construction, and cost is low, when that need not deflate, and is coordinated by gland and the sealing of the centre bore of fixed plate, good sealing effectiveness is reached, when needing broken empty deflation, drives gland to remove centre bore by cylinder, broken sky is realized, simple to operate, using effect is good.
Description
Technical field
The utility model is related to sealing plate processing technique field, more particularly to a kind of air valve for vacuum sealer.
Background technology
Vacuum heat-insulating plate is one kind in vacuum thermal insulating material, is to be composited by filling core with vacuum protection top layer,
It is effectively prevented from heat transfer caused by cross-ventilation, therefore thermal conductivity factor can be greatly lowered, for present insulation material,
Existing vacuum heat-insulating plate is in processing, it is necessary to use vacuum sealer.
Existing vacuum sealer includes sealing machine main body and is movably connected on the upper lid of sealing machine main body, upper lid and sealing
Owner's body is fixed respectively to be equiped with a vacuum device, and two vacuum devices opposition is ordinatedly set, and vacuum device includes close
Shrouding and the annular vacuum-pumping density sealing groove set around the sealing plate.Sealing is equiped with respectively in two vacuum-pumping density sealing grooves
Circle, the sealing ring protrudes the surface for vacuumizing plate.After upper lid and the pressing of sealing machine main body, two sealing rings clamp the oral area of sack
Afterwards, vacuumized in the space of two sealing plates and two sealing corral formation.Existing two vacuum devices are solid
Calmly nonadjustable to be installed on sealing machine, during work, the active force that two sealing rings are mutually held is very big, uses certain time
Afterwards, the elasticity of sealing ring decreases because of big pressure, and then causes downtrodden sealing ring to resile, two such sealing
Circle can be difficult to clamp, and cause poorly sealed, vacuumize work and be difficult to.In order to solve the above-mentioned technical problem the applicant designs
A kind of vacuum sealer, the present apparatus is the air valve for the vacuum sealer.
Utility model content
The purpose of this utility model is that, in order to solve shortcoming present in prior art, and the one kind proposed is used for vacuum seal
The air valve of mouth machine.
To achieve these goals, the utility model employs following technical scheme：
A kind of air valve for vacuum sealer, it is characterised in that：It is equal in the outer circumference of gas tube including gas tube
One group of muffler of cloth, connects the first fixed plate, opposite side in the side of gas tube and connects the second fixed plate, in the first fixed plate
Cylinder is connected, gland is connected on the piston rod of cylinder, gland is arranged in gas tube, centre bore, pressure are provided with fixed plate
Lid and centre bore corresponding matching.
Preferably, the gas tube is circular through-pipe structure, one group of through hole of circumference uniform distribution on the tube wall of gas tube, every
Be connected a muffler in individual through hole.
Preferably, the two ends of the gas tube are respectively equipped with first flange and second flange, first flange connection described the
One fixed plate, second flange connects second fixed plate.
Preferably, the gland is slidingly sealed fitted seal plate including corresponding with the centre bore, is provided with sealing plate
Sleeve, sleeve is fixed by socket on the piston rod of cylinder.
The utility model has the advantage of：The present apparatus is simple in construction, and cost is low, when that need not deflate, by gland with
The centre bore sealing of fixed plate coordinates, and reaches good sealing effectiveness, when needing broken sky to deflate, drives gland to move by cylinder
Go out centre bore, realize broken sky, simple to operate, using effect is good.
Brief description of the drawings
Fig. 1 is a kind of structural representation of air valve for vacuum sealer provided by the utility model；
Fig. 2 is Fig. 1 sectional views.
Embodiment
