Abstract
The invention discloses a self-sealing sealed connector, which comprises a connector (5) and a flange (3), wherein an annular groove (6) is arranged on the flange (3); and the annular groove (6) is provided with a dual-C-shaped sealing washer (22), of which the cross section is in a shape that a front C shape and a reverse C shape are back-to-back. The upper half part of the dual-C-shaped sealing washer (22) is higher than the surface of the flange (3). Sidewalls of the annular groove (6) of the flange (3) are respectively provided with protrusions (7) or circular rings (8) on inner and outer sides; and the protrusions (7) or circular rings (8) on two sides are respectively arranged in an inner cavity and an outer cavity of the dual-C-shaped sealing washer (22). By the sealed connector of the invention, the sealing pressure increases with the increase of fluid pressure, therefore, the sealing purpose can be achieved only by a smaller pretightening specific pressure without applying a large pressing force between the flanges, namely, the connector has self-sealing function. Thus, the sealing requirement for the places incapable of providing large pressing force is met.
Description
Technical field
The present invention relates to the connector technique field, relate in particular to a kind of self sealss hermetically sealed connector.
Background technology
The end face seal of general known connector adopts flange and panel to install, typical structure such as Fig. 1.Connector and flange are made of one structure, and the groove of annular is arranged in the flange, wherein place seal washer, and seal washer is a little more than the end face of flange.Adpting flange is connected by at least two screws with panel, when tightening screw, produces thrust between flange and the panel, act on and form sealing load on the sealing ring, make seal washer produce elasticity or plastic deformation, fill up the slit between flange and the panel, reach the purpose of sealing.Be to guarantee sealing, required sealing load is directly proportional with fluid pressure, and thrust is directly proportional between sealing load and flange and the panel.So thrust can't be accomplished enough greatly between connector flange and installation panel, when not reaching the requiring of sealing load, will produce leakage, causes seal failure.
Summary of the invention
The objective of the invention is: a kind of self sealss hermetically sealed connector is provided, it is simple in structure, has self-sealing function, under the pressure effect of fluid, produce sealing load, rather than only rely on the sealing load that the thrust between connector flange and the installation panel produces, satisfied the seal request that the place of big thrust can't be provided.
Technical scheme of the present invention is: a kind of self sealss hermetically sealed connector, it comprises connector and flange, flange is provided with cannelure, be provided with the double C-type seal washer in the cannelure, the cross section of double C shape seal washer is one positive one anti-two back-to-back shapes of C shape, and the first half of double C-type seal washer exceeds flange surface.
A kind of detailed technology scheme of the present invention is: a kind of self sealss hermetically sealed connector, it comprises connector and flange, flange is provided with cannelure, be provided with the double C-type seal washer in the cannelure, the cross section of double C shape seal washer is one positive one anti-two back-to-back shapes of C shape, and the first half of double C-type seal washer exceeds flange surface.Be respectively arranged with inside and outside both sides projection on the described flange cannelure sidewall, the both sides projection places two inside and outside cavitys of double C-type seal washer respectively.
Another kind of detailed technology scheme of the present invention is: a kind of self sealss hermetically sealed connector, it comprises connector and flange, flange is provided with cannelure, be provided with the double C-type seal washer in the cannelure, the cross section of double C shape seal washer is one positive one anti-two back-to-back shapes of C shape, and the first half of double C-type seal washer exceeds flange surface.Be respectively arranged with inside and outside both sides annulus on the described flange cannelure sidewall, the both sides annulus places two inside and outside cavitys of double C-type seal washer respectively.
Advantage of the present invention is: the invention provides a kind of improvement of hermetically-sealed construction, produce sealing load under the pressure effect of fluid, rather than the thrust that only relies between connector flange and the installation panel produces sealing load.Hermetically-sealed construction after the improvement, sealing load increases and increases along with fluid pressure, only needs less pretension specific pressure can reach the purpose of sealing, need not apply very big thrust between flange, promptly has self-sealing function.Like this, just satisfied the seal request that the place of big thrust can't be provided.

Embodiment
Embodiment one
As shown in Figure 3, Figure 4, a kind of self sealss hermetically sealed connector, it comprises connector 5 and flange 3, flange 3 is provided with cannelure 6, be provided with double C-type seal washer 22 in the cannelure 6, the cross section of double C shape seal washer 22 is one positive one anti-two back-to-back shapes of C shape, and the first half of double C-type seal washer 22 exceeds flange 3 surfaces.
Be respectively arranged with inside and outside both sides projection 7 on flange 3 cannelures 6 sidewalls, both sides projection 7 places two cavitys inside and outside the double C-type seal washer 22 respectively.
During installation, tighten screw 4, flange 3 is gradually near installation panel 1, and double C-type seal washer 22 is adjacent to installation panel 1 earlier, and and installation panel 1 between produce certain pressure, satisfy the sealing initial condition and get final product.
During use, when having pressure to be the circulation of P in the annular seal space, pressure P acts on the surface of double C-type seal washer 22, according to mechanics principle, on the contact-making surface of double C-type seal washer 22 and other objects, certainly lead to counter-force, to keep the mechanical balance of seal washer pad, be the pressure on a plurality of contact-making surfaces between pressure, flange 3 and the double C-type seal washer 22 between installation panel 1 and the double C-type seal washer 22, will be along with the increase of pressure P proportional increase, always can obtain enough sealing loads, thereby reach the purpose of sealing.
Embodiment two
As shown in Figure 5, the difference of present embodiment and embodiment one is: be respectively arranged with inside and outside both sides annulus 8 on described flange 3 cannelures 6 sidewalls.Both sides annulus 8 places two cavitys inside and outside the double C-type seal washer 22 respectively.
In this example, the both sides projection 7 that both sides annulus 8 replaces among the embodiment one, its principle is identical.
Should be pointed out that for the present invention also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned execution mode through proving absolutely.The foregoing description is as just explanation of the present invention, rather than restriction.In a word, protection scope of the present invention should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
