Abstract
The invention relates to the technical field of pipeline rush repair, in particular to an environmental-protection sealing gasket of a pipe fitting leak stopper. The environmental-protection sealing gasket of the pipe fitting leak stopper comprises sealing rings arranged at the end of the sealing gasket, and integral sealing sleeves which are connected with each other are arranged between the sealing rings. In the invention, since the integral sealing sleeves which are connected with each other are arranged between the sealing rings, the contact area of the sealing gasket and a shell is greatly increased, which not only enhances the integrity of the sealing gasket but also increases the sealing area of the sealing gasket and the shell, and therefore, the high pressure resistance and the water hammer resistance of the sealing gasket are improved, thereby the sealing performance of the whole sealing gasket is improved; meanwhile, the work reliability of the pipe fitting leak stopper is also improved.
Description
Technical field
The invention belongs to the pipe first-aid technical field, be specifically related to a kind of environmental-protection sealing gasket of pipe fitting leak stopper.
Background technique
A large amount of running water pipes, fuel tube, steam tube and petrochemical industry conveyance conduits of using in production and the life, these pipelines all might be improper because of safeguarding, geology depression and external force collision etc. are former thereby seepage or breakage take place, when seepage or damaged degree are light, use pipe fitting leak stopper that the seepage or the breakage spot of pipeline are carried out sealed envelope usually.
The structure of existing pipe fitting leak stopper comprises the housing and the sealing gasket that is arranged on the housing of opposed installation, and the sealing gasket during installation on the two housings is opposed to be abutted in together to improve sealability.Yet the high voltage performance of the sealing gasket of existing pipe fitting leak stopper and anti-water hammer performance are not good, local rollover and high-pressure liquid take place easily go out accident, cause the seal failure of pipe fitting leak stopper, therefore demand urgently improving.
Summary of the invention
The purpose of this invention is to provide a kind of environmental-protection sealing gasket of pipe fitting leak stopper, its simple structure and good seal performance.
For achieving the above object, the present invention has adopted following technological scheme: a kind of environmental-protection sealing gasket of pipe fitting leak stopper, comprise the seal ring that is arranged on place, sealing gasket end, and be provided with the stuffing box gland of connection whole shape each other between the described seal ring.
When pipe fitting leak stopper is installed, sealing gasket is placed on the housing, and with the opposed outside that is installed in the piping failure position of two housings, with bolt two housings is tightened together then and get final product, sealing gasket in the housing is installed relatively at this moment, and the corresponding end of adjacent seals bar and seal ring also is abutted together tightly.Owing to be provided with the stuffing box gland of connection whole shape each other between the seal ring among the present invention, therefore increased the area of contact of sealing gasket and housing greatly, thereby not only strengthened the integrity of sealing gasket, also increased the sealing area of sealing gasket and housing, make the high voltage performance and the anti-water hammer performance of sealing gasket get a promotion, thereby improved the sealability of whole sealing gasket, also improved the functional reliability of pipe fitting leak stopper simultaneously.

Embodiment
Shown in Fig. 1～8, a kind of environmental-protection sealing gasket of pipe fitting leak stopper comprises the seal ring 10 that is arranged on place, sealing gasket end, is provided with connection stuffing box gland 20 each other between the described seal ring 10.
Described stuffing box gland 20 can be set to whole shape, also can be set to be connected some roads Stamping Steel Ribbon or sealed muscle between the seal ring 10.
The edge part towards the pipe fitting leak stopper outside of described stuffing box gland 20 is provided with is convenient to its positioning hole that installs and fixes 22.
Because being provided with, the stuffing box gland 20 among the present invention is convenient to its positioning hole that installs and fixes 22, therefore after this sealing gasket is placed on the housing of pipe fitting leak stopper, positioning hole 22 on the sealing gasket and the bolt hole on the housing overlap, bolt hole on the screw bolt passes housing and the positioning hole on the sealing gasket 22, thereby two housings is tightened together, this moment, stuffing box gland 20 also closely combined with housing under the fastening effect of bolt, make that the high voltage performance and the anti-water hammer performance of sealing gasket are further promoted, improved and guaranteed the sealability functional reliability of pipe fitting leak stopper.
Shown in Fig. 1,4,5,8, the edge part of described stuffing box gland 20 is provided with the protuberance 21 that passes for positioning hole 22, and positioning hole 22 runs through stuffing box gland 20 up and down.By shown in the figure as can be seen, the outside towards pipe fitting leak stopper of described protuberance 21 is circular-arc outside protrusion, helping offering positioning hole 22, has also increased sealing area simultaneously, helps improving sealability.
Described seal ring 10 is set to two, and the stuffing box gland 20 that connects two seal rings 10 is the curved arc shape, also promptly is provided with angle between the medial axis of two seal rings 10, shown in Fig. 1,4, so that the present invention more is applicable to the sealing at channel bend place.
Described seal ring 10 is set to three, wherein two seal rings are oppositely arranged along same direction, the medial axis of the line of centres of these two seal rings and the 3rd seal ring is orthogonal, shown in Fig. 5,8, so that the present invention more is applicable to the sealing at branch pipe tee connection place.
