Embodiment

Such as Fig. 1, as shown in Fig. 2 a kind of manifold type pressure piping patcher provided for the present embodiment, including same two Integrated sealing (2) is installed on the inside of individual shell (1), two described shells (1), described sealing (2) both sides are provided with ring Shape card article, two described shells (1) are secured together to by attachment means.

It is preferred that described annular card article includes spiral shell in the inner side of the shell (1), particularly described connection fastener Post (3), nut (5), pad or rivet.

Application method and the description of product

Application method：The utility model is used when pressure piping is repaired, and product is arranged on needs repairing as requested Position, and use corresponding tool clamping screw, it is possible to achieve efficient mounting and dismounting, high recycling rate.

The description of product：The utility model be directed to current domestic existing pipeline patching device can not meet pressure piping repairing, The problems such as installing/dismounting inconvenience, short material service life, poor sealing performance, it is proposed that one kind is high with integrated sealing manifold type Pressure pipeline patcher, it is as follows in detail：

1) in addition to sealing, all material is all high standard potassium steel material, and plasticity good toughness, strong shock resistance is resistance to Corrosivity is high, and service life is long.

2) connected mode locks form using both sides stud, and install convenient is difficult loosening more firm.

3) integrated sealing is designed, and bearing capacity is higher, and sealing property is more preferable.In pressure piping patcher shell In side trench, and closely it is connected with pressure piping after mounting, can plays in regulation high pressure range, high pressure can be prevented Dielectric leakage in pipeline oozes out.Integral hermetic is a kind of cylinder strip-shaped frame rubber of semicircle hollow type, is high-voltage tube One of important component of road patcher.Pass through the fastener of patcher so that integral hermetic is closely pasted with pipeline outer wall Close, so as to realize the function of high pressure sealing.Lip type boss structure is added on the surface that sealing is contacted with pressure piping.And Outside compression card article after shell assigned position is sealingly mounted at, safety coefficient is higher, carries higher pressure.

4) semicircle spacing card article is equipped with outside high pressure patcher, is compressed with sealing outside into certain coning angle is sturdy, and with Shell is welded and fixed, it is ensured that sealing can carry the high pressure in pipeline.Detailed process is changed along with pipeline pressure so that Sealing starts elastic deformation, and produces pressure-bearing.The semicircle card article of elastic spacing now in sealing both sides is spacing, due to card article to Inner side is tapered, can be tightly it is stuck on pipeline outer wall, and sealing can be compressed, prevent sealing from groove abjection so that Realize that patcher has more preferable high pressure sealing performance.
