Detailed description of the invention
The core of the present invention is to provide a kind of pipe emergency repair joint, and its sealing ring varus will not occur in installation process again, has and compresses uniformity preferably, thus improving the sealing property of sealing ring；Meanwhile, its sealing ring is not susceptible to damage, thus having longer service life.
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Refer to Fig. 2, Fig. 3 and Fig. 4, structural representation when Fig. 2 is be in malcompression state in a kind of detailed description of the invention of pipe emergency repair joint provided by the present invention；Fig. 3 is structural representation when being in impaction state of the pipe emergency repair joint shown in Fig. 2；Fig. 4 is decrement analysis chart when being in impaction state of the pipe emergency repair joint shown in Fig. 2.
In a kind of detailed description of the invention, pipe emergency repair joint provided by the present invention includes shell body 21 and sealing ring 23, and wherein, sealing ring 23 is arranged between shell body 21 and pipeline to be repaired 22, and the internal diameter of sealing ring 23 is more than or equal to the external diameter of pipeline 22 to be repaired；This pipe emergency repair joint strengthens internal diameter and the external diameter of shell body 21 and sealing ring 23 on the basis of original structure, and arc length is constant, the internal diameter making sealing ring 23 is consistent with the external diameter of pipeline 22 to be repaired, avoid the upset deformation that opening occurs because of frictional force ambassador's sealing ring during installation, have and compress uniformity preferably, thus improving the sealing property of sealing ring 23, and owing to compressing uniformly, sealing ring 23 uniform force, so that sealing ring 23 is not susceptible to damage, has longer service life.
Above-mentioned sealing ring 23 can be conventional use of various forms of sealing rings 23 in this area, for instance the common O of one end open, or hollow sealing ring etc..This sealing ring can adopt the materials such as nitrile rubber, natural rubber, neoprene, EP rubbers, fluorubber, silicone rubber and Blend rubber to be fabricated by.
As long as it is apparent that ensure that sealing ring 23 has enough sealing properties, and having predetermined compression performance, its concrete material is in this no limit.
The material of above-mentioned shell body 21 can be various metal material, for instance cast iron or aluminium alloy etc..
The internal diameter of sealing ring 23 is equal to the external diameter of described pipeline 22 to be repaired, so that sealing ring 23 and shell body 21 are fitted better, making in installation process, shell body 21 is applied to the active force of sealing ring 23 and more uniformly acts on sealing ring 23, further increases the compression uniformity of sealing ring 23.
It is apparent that the internal diameter of sealing ring 23 is also not limited to be equal to the external diameter of pipeline 22 to be repaired, as long as pipeline 22 to be repaired can be set in, and ensureing homogeneous compaction, the internal diameter of sealing ring 23 can also slightly larger than the external diameter of pipeline 22 to be repaired in suitable scope.
The external diameter of above-mentioned sealing ring 23 can be equal to the internal diameter of described shell body 21, in order in installation process, shell body 21 is applied to the active force of sealing ring 23 and more uniformly acts on sealing ring 23, further increases the compression uniformity of sealing ring 23.It is apparent that the external diameter of sealing ring 23 is also not limited to be equal to the internal diameter of shell body 21, it can also be slightly less than the internal diameter of shell body 21 in allowed limits.
Above-mentioned shell body 21 can include the first housing 211 and the second housing 212 of dismantled and assembled connection, in order to realizes installation and the fastening of pipe emergency repair joint more easily.It is apparent that shell body 21 can also be integral type structure, by the mode press-fited, sealing ring 23 is installed.
It is pointed out that ordinal numbers such as " first, second " described in literary composition is the different structure in order to distinguish same names, only for describing conveniently, do not indicate that certain order, more should not be construed as any restriction.
First housing 211 and the second housing 212 can pass through bolt 24 and be removably connected, and when two housings compresses sealing ring 23, by screwing bolts 24 i.e. adjustable thrust, thrust is easy to adjust；Meanwhile, bolted mode dismounts more convenient, improves the installation effectiveness of pipe emergency repair joint.
Above-mentioned bolt 24 can arrange two, and two bolts 24 connect the first housing 211 and the second housing 212 at both ends open place.
The mode that said first shell 211 is also not limited to be bolted with the second housing 212 realizes dismantled and assembled connection, and both can also pass through the conventional use of removable connected mode of this area kind and connect, for instance use axis tile to connect the mode of fastening.
First housing 211 may further include at least two parts being removably connected, and similarly, the second housing 212 can also farther include at least two parts being removably connected.
Above a kind of pipe emergency repair joint provided by the present invention is described in detail.Principles of the invention and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method and the core concept thereof of the present invention.It should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to the present invention carries out some improvement and modification, these improve and modify in the protection domain also falling into the claims in the present invention.
