Abstract
The utility model discloses a leak-proof sealing device. The leak-proof sealing device comprises an end face body with a sealing groove, an elastic sealing body and a sealing gland, wherein the elastic sealing body is embedded into the sealing groove of the end face body, the upper end thereof is higher than a notch end face of the end face body, and the elastic sealing body is provided with a hollow cavity for sealing gas. The technical scheme adopts the closed sealing mode, the hollow cavity of the leak-proof elastic sealing body forms a sealed air bag, and the air bag can deform after being extruded by the sealing gland and quickly recover when not extruded. The leak-proof sealing device has the advantages of simple structure requirement, favorable sealing effect, long life of sealing members, and the like.
Description
Technical field
The utility model relates to the sealing of the non-pressure vessel end face of frequent switching, is specially adapted to the sealed against leakage of rubbish shipment bucket, with the leak-proof sealing device that prevents that rubbish and sewage from going out to ooze out from bung in transhipment.
Background technology
The structure of existing sealing arrangement comprises the end face body 1 that has seal groove as shown in Figure 1 and Figure 2, solid sealing member (rounded seal 20 or serrated seal 21) and gland cover 3.The solid rubber sealing member the 20, the 21st among the figure, embeds in the seal groove continuously, the end face body 1 that has seal groove is to be connected through the hinge with gland cover 3, after solid rubber sealing member 20,21 is subjected to gland cover 3 crimps, will between end face body 1 that has seal groove and gland cover 3, form sealing surface, realize sealing.But there is following problem in actual use in these versions:
One, to seal required thrust big for solid rubber, therefore requires gland cover and groove body to have enough rigidity.This just need be its complex structural designs, and structural weight increases, and cost improves;
Two, rubber seal is difficult to return to original scantling of structure after frequent crimp, causes rubber seal to scrap in advance, and service life is short, the maintenance cost height;
Three, to exist bigger space to cut contact surface in inside grooves little for Yuan Xing sealing member, and the in-to-in sealing effectiveness is bad, the zigzag outside frequent migratory stain thing that is sealed in, and residual garbage in sawtooth easily, thus influence sealing effectiveness.
Summary of the invention
In order to solve above-mentioned technical matters, the purpose of this utility model provides a kind of leak-proof sealing device that improves leak tightness, reduces thrust, has advantages such as structural requirement is simple, good sealing effect, seal life length.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of leak-proof sealing device, comprise the end face body, elastic sealed body and the gland cover that have seal groove, in the seal groove of described elastic sealed body embedding end face body and its upper end exceeds the notch end face of end face body, and described elastic sealed body has the hollow lumen of confining gas.
The material of elastic sealed body and interior envelope gas can be multiple, but consider cost, and preferred: above-mentioned elastic sealed body is a rubbery sealed body, its hollow lumen inner sealing air.
Elastic sealed body is laid shape and is changed with the layout shape of described embedded sealed groove, as circle, polygon etc.As preferably, above-mentioned elastic sealed body ringwise, its hollow lumen is also ringwise.
As preferably, the lower end that above-mentioned elastic sealed body embeds end face body back seal groove is a serration, and described elastic sealed body exceeds the upper end of end face body notch end face for circular or oval.Adopting one side is that similar round simultaneously is zigzag hollow rubber sealing member, combines circular and serration leak free advantage, and hollow structure has reduced the thrust that satisfies rubber seal, thereby simplifies the structure design, reduces the material weight of structure; Improve the service life and the reliability of sealing member.
The utility model is owing to adopted above technical scheme, adopt airtight envelope mode, the hollow lumen of leakproof elastic sealed body forms the fully enclosed air bag, this air bag can be subjected to gland cover extruding back distortion, and very fast recovery when not being squeezed has advantages such as structural requirement is simple, good sealing effect, seal life length.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
A kind of leak-proof sealing device as shown in Figure 3, comprise the end face body 1, elastic sealed body 2 and the gland cover 3 that have seal groove, in the seal groove of described elastic sealed body 2 embedding end face bodies 1 and its upper end exceeds the notch end face of end face body 1, and described elastic sealed body 2 has the hollow lumen of confining gas.In the present embodiment, described elastic sealed body 2 is a rubbery sealed body, its hollow lumen inner sealing air; As shown in Figure 4, described elastic sealed body 2 ringwise, its hollow lumen is also ringwise; As Fig. 3, shown in Figure 5, the interior bottom surface, lower end of notch that described elastic sealed body 2 embeds end face body 1 back seal groove is a serration, and described elastic sealed body 2 exceeds the upper end face of end face body 1 notch end face for oval;
The hollow lumen inner sealing air bag of described elastic sealed body 2, sealing means are that sealing member 2 is sealed to loop configuration and sealed at both ends.On the docking port that forms seal ring, adopt high strength gluing, under certain pressure, stick into one and guarantee that sealed body cavity forms the fully enclosed air bag.The air bag that described this kind leakproof seal body forms has reduced the required thrust of rubber seal; And gas compression in the air bag in it after sealing member is squeezed, increased pressure makes sealing surface stressed evenly, increases sealing effectiveness.After outer squeese pressure was removed, gas expanded and helps to recover the original-shape of sealing member, prolongs the service life of sealing member, improves the leak free reliability.
Present embodiment only is a simplified example of the present utility model, is not to be used for limiting protection domain of the present utility model, and all equivalences of doing according to content of the present utility model change and modify, and all fall in the protection domain of the present utility model.
