Description
Technical field
The present invention relates to pressure pipeline field.Specially a kind of clamp with press leaking stoppage.
Background technology
Using pipeline gas, either liquid has been widely used for the gas in various industries pipeline or liquid tool
There is higher pressure, when leak source occurs in pipeline, under the effect of the pressure, gas and liquid will produce leakage, especially
At the position of two pipes connection, it is easier to leak.If medium is dangerous liquid or gas, environment is not only resulted in
Pollution, can also bring prodigious security risk, enterprise to also tend to be forced to stop production to production, cause economic loss.In order not to shadow
The conveying for ringing medium needs to carry out pressure sealing.For the higher pipeline of pressure ratio, need to form sealing using fixture in leak source
Cavity, in the cavity be perfused fluid sealant to block leak source.Two sections of conveyance conduits often have the feelings of decentraction in connection
Condition causes pipeline junction to have different degrees of mismatch.It, can be right if carrying out leak stopping to pipeline junction using concentric fixture
Junction generates the leakage for often aggravating leak source perpendicular to axial power or generates new leak source, and leak stopping is caused to fail.
Invention content
Present invention solves the technical problem that the shortcomings that being the leakage for overcoming existing fixture to be easy aggravation pipeline junction,
A kind of clamp with press leaking stoppage being suitable for carrying out pipeline junction or its neighbouring position leak stopping is provided.
The clamp with press leaking stoppage of the present invention carries out leak stopping, the pressure sealing for the leak source to two pipeline junctions
Fixture includes four fixture blocks, and each fixture block all has semicircular curved surface and semicircular sealing surface, the sealing
Face is located at one end of the curved surface, when the first fixture block and the assembling of the second fixture block are fixed together, the song of the first fixture block
The curved surface of face and the second fixture block forms the first circular curved surface that can surround first pipe outer wall, the sealing surface of the first fixture block with
The sealing surface of second fixture block forms the first circular seal face that cooperation can be sealed with the first pipe outer wall, in third fixture
When being fixed together with the assembling of the 4th fixture, the curved surface of third fixture block and the curved surface of the 4th fixture can be formed around second pipe
Second circular curved surface of outer wall, the sealing surface of third fixture block and the sealing surface of the 4th fixture can be formed with outside the second pipe
Second circular seal face of wall sealing cooperation, in the first fixture block and third fixture block assembling is fixed together and institute
State that the assembling of the second fixture block and the 4th fixture block is fixed together and first circular curved surface and second circular curved surface are tight
When adjacent, first circular curved surface surrounds glue injection cavities jointly with the second circular curved surface, and four fixture blocks all have and the injecting glue
The injecting glue through-hole that chamber communicates.When first pipe and second pipe are when junction generates eccentric dislocation, i.e. the axis of the two does not exist
On the same line, after clamp with press leaking stoppage of the invention and first pipe and second pipe complete assembly, the first circular curved surface with
Second circular curved surface is also dislocation, therefore, will not apply in first pipe and second pipe junction and destroy existing connection shape
The power of condition, such fixture block have well adapted to first pipe and the connection of second pipe, preferably with pressure to obtain
The effect of leak stopping.
Preferably, first circular seal face and the second circular seal face have the sealing of a plurality of circumferentially extending convex
It rises, so as to form a plurality of linear sealing, can further improve the sealing performance of sealing surface.

Specific implementation mode
The clamp with press leaking stoppage of the present invention is used to carry out leak stopping to the leak source of two pipeline junctions or its neighbouring position.Such as
Shown in Fig. 1-3, the clamp with press leaking stoppage includes four fixture blocks, and each fixture block all has semicircular curved surface and half
Circular sealing surface, the sealing surface are located at one end of the curved surface.As depicted in figs. 1 and 2, in assembled state,
The sealing surface of one fixture block 1 and the second fixture block 2 is located at the upper end of its curved surface, the sealing of third fixture block 3 and the 4th fixture block 4
Face is located at the lower end of its curved surface.
As shown in Figures 2 and 3, when the first fixture block 1 and the assembling of the second fixture block 2 are fixed together, the first fixture block 1
Curved surface and the second fixture block 2 curved surface formed can surround 15 outer wall of first pipe the first circular curved surface 5, the first fixture block 1
Sealing surface and the second fixture block 2 sealing surface formed can with 15 outer wall of the first pipe seal cooperation the first circular seal
Face 7.When third fixture and the assembling of the 4th fixture are fixed together, the curved surface of third fixture block 3 and the curved surface of the 4th fixture can
The second circular curved surface 6 around 16 outer wall of second pipe is formed, the sealing surface of third fixture block 3 and the sealing surface of the 4th fixture can
Form the second circular seal face 8 with the sealing cooperation of 16 outer wall of the second pipe.In the first fixture block 1 and the third
The assembling of fixture block 3 is fixed together and the second fixture block 2 and the assembling of the 4th fixture block 4 are fixed together and first circle
Shape curved surface 5 and second circular curved surface 6 close to when, first circular curved surface, 5 and second circular curved surface 6 surrounds injecting glue jointly
Chamber 9, the first close round cover and the second circular seal face 8 are located at the both ends of glue injection cavities 9.Four fixture blocks all have and the note
The injecting glue through-hole 10 that glue chamber 9 communicates, in the present embodiment, the axis of the injecting glue through-hole 10 are vertical with the axis of pipeline.
As shown in figure 4, in use, making the first fixture block 1 and the second fixture block 2 and the cooperation of first pipe 15, the first fixture
The first circular seal face 7 that the sealing surface of block 1 and the second fixture block 2 is formed is fitted close with 15 outer wall of first pipe, forms ring
The sealing of shape.Third fixture block 3 and the 4th fixture block 4 and the 4th tube fit, third fixture block 3 are close with the 4th fixture block 4
The the second circular seal face 8 and the outer wall of second pipe 16 that cover is formed are fitted close.First circular curved surface 5 is around first pipe
