Description
Technical field
The utility model relates to high pressure static seal field, specifically relates to a kind of clip quick open type major diameter container sealing device.
Background technique
Clip quick open type major diameter container comprises cylindrical shell and end socket, on cylindrical shell and end socket, be all fixed with flange, correspondence is referred to as shell flange and cover flange, cover flange is buckled on shell flange, and fix by clip, the sealing surface of shell flange along the circumferential direction has groove, in groove, be provided with seal ring, between shell flange and cover flange, by seal ring, seal, when container diameter is large and pressure is higher, clip easily deforms, seal ring is easily got in the gap between the sealing surface of shell flange and the sealing surface of cover flange by pressure, cause clip and shell flange, the equal moment increase of frictional force between cover flange is doubly a lot, clip can not rotate, the end socket of container cannot be opened.
Model utility content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, a kind of clip quick open type major diameter container sealing device is provided, can avoid seal ring to be got in the gap between the sealing surface of shell flange and the sealing surface of cover flange by pressure, clip can rotate, and the end socket of container is convenient to open.
The utility model provides a kind of clip quick open type major diameter container sealing device, comprise shell flange and cover flange, the sealing surface of described shell flange along the circumferential direction has groove, in described groove, be provided with seal ring, described cover flange is buckled on shell flange, and fix by clip, in described groove, being also provided with back-up ring, described back-up ring is positioned at the outside of seal ring; The sealing surface of described cover flange is along the circumferential direction provided with the positive stop lug boss mating with groove, and described positive stop lug boss stretches in groove, blocks seal ring, and positive stop lug boss and back-up ring are spacing in groove by seal ring.
On the basis of technique scheme, the clear width of described groove has a plurality of breach, and the sealing surface of shell flange has and breach fixed groove one to one, is all fixed with the catch for baffle seal circle in each fixed groove, all catch all extend to seal ring, and seal ring is fixed.
On the basis of technique scheme, the longitudinal section of described groove is rectangular.
On the basis of technique scheme, described seal ring is O shape circle.
Compared with prior art, advantage of the present utility model is as follows:
(1) arranged outside of the seal ring in the utility model has back-up ring, the sealing surface of cover flange is along the circumferential direction provided with the positive stop lug boss mating with groove, positive stop lug boss stretches in groove, seal ring is blocked, positive stop lug boss and back-up ring are spacing in groove by seal ring, can effectively avoid seal ring to be got in the gap between the sealing surface of shell flange and the sealing surface of cover flange by pressure, clip can be rotated, the end socket of container is convenient to open.
(2) seal ring in the utility model is blocked by back-up ring, seal ring compresses back-up ring after bearing pressure, because back-up ring has certain degree of hardness, be difficult to be got in the gap between the sealing surface of shell flange and the sealing surface of cover flange, thereby avoid seal ring to be got in the gap between the sealing surface of shell flange and the sealing surface of cover flange, clip can be rotated, and the end socket of container is convenient to open.
(3) inner side of the seal ring in the utility model is provided with catch, catch is fixed seal ring, can further avoid seal ring to be got in the gap between the sealing surface of shell flange and the sealing surface of cover flange by pressure, clip can be rotated, the end socket of container is convenient to open.
Accompanying drawing explanation
Fig. 1 is the structural representation of clip quick open type major diameter container sealing device in the utility model embodiment.
Reference character: 1-shell flange, 2-cover flange, 3-groove, 4-back-up ring, 5-seal ring, 6-catch, 7-positive stop lug boss.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Shown in Figure 1, the utility model embodiment provides a kind of clip quick open type major diameter container sealing device, sealing device comprises shell flange 1 and cover flange 2, the sealing surface of shell flange 1 along the circumferential direction has groove 3, in groove 3, be provided with seal ring 5, cover flange 2 is buckled on shell flange 1, and fixes by clip, in groove 3, be also provided with back-up ring 4, back-up ring 4 is positioned at the outside of seal ring 5; The sealing surface of cover flange 2 is along the circumferential direction provided with the positive stop lug boss 7 mating with groove 3, positive stop lug boss 7 stretches in groove 3, block seal ring 5, positive stop lug boss 7 is spacing in groove 3 by seal ring 5 with back-up ring 4, thereby avoids seal ring 5 to be got in the gap between the sealing surface of shell flange 1 and the sealing surface of cover flange 2 by pressure.
The clear width of groove 3 has a plurality of breach, the sealing surface of shell flange 1 has and breach fixed groove one to one, in each fixed groove, be all fixed with the catch 6 for baffle seal circle 5, all catch 6 all extend to seal ring 5, seal ring 5 is fixed, thereby further avoids seal ring 5 to be got in the gap between the sealing surface of shell flange 1 and the sealing surface of cover flange 2 by pressure.
The longitudinal section of the utility model further groove 3 is rectangular, and seal ring 5 is O shape circle.
The utility model is not only confined to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a utility model or akin technological scheme, all within its protection domain.
