Description
Technical field
The utility model belongs to the pipe first-aid technical field, is specifically related to a kind of sealing gasket for half joint.
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 needing repairing, use the Hough joint that the seepage or the breakage spot of pipeline are carried out sealed envelope usually.
The structure of existing Hough joint comprises the housing and the sealing gasket that is arranged on the housing of opposed installation, and the structure of sealing gasket is symmetrically distributed about the medial axis of housing, 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 existing sealing gaskets of Hafu joint 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 Hough joint, therefore demand urgently improving.
The model utility content
The purpose of this utility model provides a kind of sealing gasket for half joint, its simple structure and good seal performance.
For achieving the above object, the utility model has adopted following technological scheme: a kind of sealing gasket for half joint, comprise the seal ring that is arranged on both sides, be provided with between the described seal ring and connect the Stamping Steel Ribbon of end each other, described Stamping Steel Ribbon is provided with is convenient to its positioning block that installs and fixes and/or locating slot.
When the Hough joint 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, and with bolt two housings is tightened together and to 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 its positioning block that installs and fixes and/or locating slot, therefore Stamping Steel Ribbon will closely combine with housing, make the high voltage performance and the anti-water hammer performance boost of Stamping Steel Ribbon, thereby improved the sealability of whole sealing gasket, also improved the functional reliability of Hough joint simultaneously.

Embodiment
Shown in Fig. 1～4, a kind of sealing gasket for half joint, comprise the seal ring 10 that is arranged on both sides, be provided with between the described seal ring 10 and connect the Stamping Steel Ribbon 20 of end each other that described Stamping Steel Ribbon 20 is provided with is convenient to its positioning block that installs and fixes and/or locating slot 23.
On the described Stamping Steel Ribbon 20 positioning block or locating slot can be set, better so that positioning block to be set usually, can increase the structural strength of Stamping Steel Ribbon 20 simultaneously.
Stamping Steel Ribbon 20 is arranged in the longitudinal fluting of Hough joint housing, and 10 of seal rings are arranged in the two ends place of Hough joint housing, and seal ring 10 and Stamping Steel Ribbon 20 have been formed a complete sealing system jointly.It is more tight that positioning block in the utility model and/or locating slot 23 make that Stamping Steel Ribbon 20 combines with Hough joint housing, thereby improved the sealability between adjacent seals bar and Stamping Steel Ribbon and the housing, also improved the high voltage performance and the anti-water hammer performance of whole Hough joint simultaneously.
Further, the cross section of described Stamping Steel Ribbon 20 is wide at the top and narrow at the bottom trapezoidal, and the end face at trapezoidal upper base place links to each other with the end face of seal ring 10, and described positioning block 23 is arranged on the end face at the trapezoidal place of going to the bottom, as shown in Figure 4.
During installation Stamping Steel Ribbon 20 is embedded at Hough joint housing longitudinally in the groove, because positioning block 23 is arranged on the end face at the trapezoidal place of going to the bottom, it also is the bottom that positioning block 23 is arranged on Stamping Steel Ribbon 20, and Hough joint housing is provided with and positioning block 23 corresponding recesses, positioning block 23 is aimed at the recess on the housing and embedded can be with Stamping Steel Ribbon 20 installation in position, therefore positioning block 23 not only improves the sealability of Hough joint, and is convenient to install and construction.
Further, described positioning block 23 is for being arranged on the projection on the Stamping Steel Ribbon 20, and positioning block 23 is along the length direction setting of Stamping Steel Ribbon 20, and positioning block 23 is separately positioned on the two end part and the middle part of Stamping Steel Ribbon 20, shown in Fig. 1,5.
Positioning block 23 is arranged on the Stamping Steel Ribbon 20 as projection or raised line, helps improving the structural strength of Stamping Steel Ribbon 20; And a plurality of positioning blocks 23 are set along the length direction of Stamping Steel Ribbon 20, and then help improving the harmony of the intensity that Stamping Steel Ribbon 20 directly makes progress at Hough joint housing, help the reliably working of Stamping Steel Ribbon 20.
As preferred version of the present utility model, described Stamping Steel Ribbon 20 comprises first Stamping Steel Ribbon 21 and second Stamping Steel Ribbon 22 that be arranged in parallel, position and the position of second Stamping Steel Ribbon 22 of described first Stamping Steel Ribbon 21 after about the medial axis symmetry of seal ring 10 is different, as shown in Figure 5.
Position and the position of second Stamping Steel Ribbon 22 of described first Stamping Steel Ribbon 21 after about the medial axis symmetry of seal ring 10 is different, promptly first Stamping Steel Ribbon 21 and second Stamping Steel Ribbon 22 are not symmetrical about the medial axis of seal ring 10 yet, this setup of sealing gaskets of Hafu joint makes win Stamping Steel Ribbon 21 and second Stamping Steel Ribbon 22 not exclusively abut in together or not abut in together when opposed installation, the sealing effect of Stamping Steel Ribbon is realized by the respective outer side edges of Stamping Steel Ribbon and Hough joint housing, because the shell material of Hough joint is a metal, therefore the structural strength of Hough joint housing is higher, thereby housing matches with Stamping Steel Ribbon and has greatly improved the high voltage performance and the anti-water hammer performance of Hough joint, has guaranteed the sealability of Hough joint.
Further, as shown in Figure 5, the distance of the outer rim of described first Stamping Steel Ribbon 21 and seal ring 10 medial axis is greater than the outer rim of second Stamping Steel Ribbon 22 and the distance of seal ring 10 medial axis, and the cross-sectional width of first Stamping Steel Ribbon 21 is greater than the cross-sectional width of second Stamping Steel Ribbon 22, and described positioning block 23 is arranged on first Stamping Steel Ribbon 21.
Make the cross-sectional width of the cross-sectional width of first Stamping Steel Ribbon 21 greater than second Stamping Steel Ribbon 22, can so that the lateral overlap of the inboard of first Stamping Steel Ribbon 21 and second Stamping Steel Ribbon 22 together, and can be under the prerequisite that guarantees Hough joint sealability, reduce material consumption, reduce the volume of Hough joint, help reducing Hough joint weight and be convenient to installation.Because the cross-sectional width of first Stamping Steel Ribbon 21 is bigger, therefore positioning block 23 is set thereon, not only be easy to make, and help installation.
