The utility model has the advantages of quick gas filling and automatic seal after gas filling, and can check the pressure in the air bag at any moment; thereby, the utility model is particularly applied to the air bag used under the hard conditions of high temperature or low temperature, etc.; moreover, the detachable valve base can quickly discharge air with no gas leftover.
Description
Technical field
The utility model relates to a kind of Air filling and discharging valves device, refers to a kind of quick Air filling and discharging valves device that is installed on the air bag especially, and this air bag comprises the air filling sack that logistics is used, daily sack etc.
Background technique
Filling air bag is the big bag that is full of expanded air, resists goods moving in transportation process so that enough pressure to be provided.Air bag all provides different size according to different situations, and the existing aerating and exhaust device that is installed on the air bag is various day by day, multi-functional, not only makes every effort to prevent more reliably the gas leakage in the sack, and also requirement can be discharged a bag interior gas apace.Especially for the bigger air bag series products of volume.Air bag can be made or be made by moulding the cloth lining by the paper of a lot of antiseepage linings and the different numbers of plies, and well-known, this is the technology of a maturation.Paper product usually can only be with once, and come fast discharging air and be compressed simply by scratching sack, and allow sack to be taken up and light unloaded of cargo from its filling position.Therefore advise sack Polypropylence Sheet lining, it can be reused in a lot of occasions, and valve of its needs can allow not cut out an openning on airbag wall and air in the emptying air bag.Additional valves can allow sack to shrink fast, and this usage provides using the bubble-tight machines meeting of sack in the past.Disposable paper bag has a serious problem, and this problem is that they can not detect before usefulness, so they have the mortality up to 30%.If sack during transportation can't keep the air in the sack, the distance between lade also can become loose and lose the filling function; If fill air bag unexpected inefficacy in transportation process, it is obviously impossible to attempt to change sack in the way.Therefore the detection in advance of sack is crucial, also provides a considerable advantage for sale.
Air valve can simply use, as long as there is a simple joint to be connected with air valve pressurized air is charged into air bag.In many cases, joint with can not lock voluntarily after air valve is connected, need artificially control, require joint is pushed away on air valve, if can resist the object that receives thrust, operating difficulties without any suitable in the back of air bag.
More than design all comes simple inflation sack according to purposes, and sack is easily torn venting.Therefore this design does not allow to test air bag or repeated use in advance, because air bag can not be shunk fast.
Also have a kind of valve, sack is shunk fast by moving, and perhaps unclamps the valve rod of relative broad, to such an extent as to air can be apace hole from the bonnet discharge.In this design, valve itself is installed in the bonnet, very simply splitting that pipe forms in the middle of the bonnet by one.Packing is inserted by splitting pipe by nozzle, and struts and split tubular portion and allow air to enter.When taking off nozzle, two releases that just stop air by the air compression part of splitting together.Yet such valve is very coarse also can leakage air, and the user has to nozzle or top are forced into valve.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of more reasonable structure is provided, and can effectively prevent gas leak, makes things convenient at any time to detect the pressure in the air bag and make air bag charge and discharge gas Air filling and discharging valves device easily and fast.
The technological scheme that the utility model solves the problems of the technologies described above is: a kind of Air filling and discharging valves device, comprise the Air filling and discharging valves core, and valve seat, valve gap and gas-charging connection comprise,
One has the valve seat of flange plate, has unlimited cavity, and upper outside is provided with annular recess, the outside, middle part is provided with protruding rank, and a flange plate is installed on the airbag wall opening, and the bottom is provided with dog, the inboard, middle part is provided with a bulge loop, and wherein, described valve seat is integral type valve seat or split type valve seat;
One spool, the lower end is a columnar head, columnar head is provided with annular recess, the upper end is " one " font head or I-shaped head or cross head, upper and lower end is connected by the less joint of diameter, is example with I-shaped head, and breach is venting channels, the venting channels area helps venting greatly, and its shape can also be first-class for T-shaped head, man type;
One seal ring is arranged on the annular groove of spool lower end, and ring set is after on the annular groove, and its size just in time is complementary with the inboard bulge loop of valve seat, thereby plays the purpose of blocking-up air-flow;
