Abstract
The utility model belongs to the technical field of pipeline repairing and relates to a pipeline leak stopper sealing pad in particular. The pipeline leak stopper sealing pad includes seal rings arranged at the end part of the sealing pad; sealing strips manually connected with end parts are arranged between the seal rings; and locating holes which are convenient to install and fix the sealing strips are arranged on the sealing strips. As the sealing strips are provided with the locating holes which are convenient to install and fix the sealing strips, when the sealing pad is arranged on shells, the locating holes and the bolt holes on the shells are overlapped; bolts penetrate the bolt holes on the shells and the locating holes on the sealing pad in sequence, thereby tightly fastening the two shells together; meanwhile, the sealing strips are tightly combined with the shells under the fastening effect of the bolts to improve the high pressure resistance and water hammering resistance of the sealing strips, thereby improving the sealing performance of the whole sealing pad, and simultaneously improving the working reliability of the pipeline leak stopper.
Description
Technical field
The utility model belongs to the pipe first-aid technical field, is specifically related to a kind of pipeline stopper sealing gasket.
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 utility model provides a kind of pipeline stopper sealing gasket, its simple structure and good seal performance.
For achieving the above object, the utility model has adopted following technological scheme: a kind of pipeline stopper sealing gasket, comprise the seal ring that is arranged on place, sealing gasket end, be provided with between the described seal ring and connect the Stamping Steel Ribbon of termination portion each other, described Stamping Steel Ribbon is provided with is convenient to the positioning hole that it installs and fixes.
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.Because being provided with, the Stamping Steel Ribbon in the utility model is convenient to the positioning hole that it installs and fixes, therefore after this sealing gasket is placed on the housing, positioning hole 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, thereby two housings is tightened together, this moment, Stamping Steel Ribbon also closely combined with housing under the fastening effect of bolt, make the high voltage performance and the anti-water hammer performance of Stamping Steel Ribbon get a promotion, and then 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 pipeline stopper sealing gasket, comprise the seal ring 10 that is arranged on sealing gasket end place, be provided with between the described seal ring 10 and connect the Stamping Steel Ribbon 20 of head each other that described Stamping Steel Ribbon 20 is provided with is convenient to its positioning hole that installs and fixes 24.
Further, described seal ring 10 semicirculars in shape, Stamping Steel Ribbon 20 comprises and connects first Stamping Steel Ribbon 21 and second Stamping Steel Ribbon 22 of seal ring 10 heads each other, and the position of described first Stamping Steel Ribbon 21 after about the medial axis symmetry of seal ring 10 is identical with the position phase XOR of second Stamping Steel Ribbon 22.
The sealing gasket that has first Stamping Steel Ribbon 21 and second Stamping Steel Ribbon 22 not only comprises the situation that is used for pipeline elbow bend place shown in Fig. 1～4, also comprises the situation that is used for pipe coupling place and pipeline itself; When the position of described first Stamping Steel Ribbon 21 after about the medial axis symmetry of seal ring 10 is identical with the position of second Stamping Steel Ribbon 22, also i.e. first Stamping Steel Ribbon 21 and the identical situation of second Stamping Steel Ribbon, 22 shapes; Position and the position of second Stamping Steel Ribbon 22 when different of described first Stamping Steel Ribbon 21 after about the medial axis symmetry of seal ring 10, then refer to first Stamping Steel Ribbon 21 and the different and/or variform situation in second Stamping Steel Ribbon, 22 positions, this moment, the sealability of sealing gasket was better.
The cross section of described Stamping Steel Ribbon 20 is up-narrow and down-wide trapezoidal, and trapezoidal upper base links to each other with the housing of pipe fitting leak stopper, is beneficial to Stamping Steel Ribbon 20 is embedded in the housing that is installed to pipe fitting leak stopper.
Shown in Fig. 1,4,5,8, described Stamping Steel Ribbon 20 be provided with the protuberance 23 that passes for positioning hole 24, and positioning hole 24 runs through Stamping Steel Ribbon 20 up and down, by shown in the figure as can be seen, the width at described protuberance 23 places is greater than the width at Stamping Steel Ribbon 20 other positions, to help offering positioning hole 24, also increased sealing area simultaneously, help improving sealability.
The outside towards pipe fitting leak stopper of described protuberance 21 is circular-arc outside protrusion.
Shown in Fig. 1,4, described seal ring 10 is set to two, and is provided with angle between the medial axis of two seal rings 10, is the curved arc shape as the Stamping Steel Ribbon among Fig. 1,4 22, so that the utility model more is applicable to the sealing at channel bend place.
Shown in Fig. 5,8, described seal ring 10 is set to three, wherein two seal rings are oppositely arranged along same direction, and the medial axis of the line of centres of these two seal rings and the 3rd seal ring is orthogonal, so that the utility model more is applicable to the sealing at branch pipe tee connection place.
