Multi -level tubular says capping, through setting up first shutoff portion to it decides the portion from the card that the pipeline mouth is deviate from to be equipped with the first shutoff portion that prevents in first shutoff portion, the rethread sets up the screw thread through -hole in first shutoff portion to have second shutoff portion at screw through -hole in -connection, the accessible loosens second shutoff portion and realizes when needing the flowing back in the pipeline, when second shutoff portion is difficult to loosen, can be with blocking the unblock of fixed portion, and with first shutoff portion take out from the pipeline in can, its simple structure is reliable, has fine practicality.
Description
Technical field
This utility model is related to technical field, more particularly to a kind of multi-stage pipeline capping.
Background technology
Generally require to block the outlet of pipeline when pipeline connects, capping of the prior art is most
It is threadingly attached to be directly fixed at pipeline opening, the pressure in due to pipeline is excessive when needing pressure release,
Generally require to disassemble closure.But because the screw thread of life-time service, capping and pipeline will get rusty,
It is now extremely difficult during dismounting capping, even need capping could be removed pipe cutting sometimes, give
Construction causes very big inconvenience.
Utility model content
In view of this, this utility model is directed to a kind of multi-stage pipeline capping, in order to pipeline pressure release.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
A kind of multi-stage pipeline capping, including the first closure for being embedded in pipeline to block pipeline opening
Portion, in first closure part be provided with can engaging in it is on pipeline outer peripheral face, with prevent it is described first closure
The engaging portion that portion departs from pipeline；The tapped through hole being communicated with first closure part inside pipeline,
Also include the second closure part being threadedly coupled with the tapped through hole.
Further, outer face in first closure part is provided with and the tapped through hole concentrically line
Bellmouth, on second closure part auxiliary section is fixed with, logical with the screw thread in second closure part
When hole connects, the auxiliary section can be with the bellmouth elastic packing.
Further, the engaging portion include being connected with first closure part and can be connected in pipeline periphery
Access Division on face, and be sheathed on the Access Division can elastic clamping clip, set on the clip
Have and order about the lower breach that open can clip in external force, the connection group for clamping clip is provided with the clip
Part.
Further, the auxiliary section is made up of rubber.
Relative to prior art, this utility model has the advantage that：
(1) multi-stage pipeline capping described in the utility model, including being embedded in pipeline to enter pipeline opening
First closure part of row closure, and engaging portion is provided with the first closure part, the engaging portion can prevent the first envelope
Deviate from from pipeline opening in stifled portion；Again by being threaded through hole, and the spiral shell in tapped through hole on the first closure part
Stricture of vagina is connected with the second closure part, can be realized by loosening the second closure part when discharge opeing is needed in pipeline, when
When second closure part is not easy to loosen, by the way that engaging portion is unlocked, and the first closure part can be taken from pipeline
The purpose of pipeline pressure release is out capable of achieving, its is simple and reliable for structure, there is good practicality.
(2) by arranging the bellmouth with tapped through hole concentrically line on the outer face of the first closure part,
The auxiliary section coordinated with bellmouth is fixed with second closure part, arranging bellmouth can be in the second closure part and the
Guiding is played a part of in one closure part when connecting, and sealing effectiveness on the other hand can be caused more preferable.
(3) auxiliary section is of rubber by being made up, because caoutchouc elasticity deforms, in the first closure part and second
Closure part can prevent from producing gap between bellmouth when connecting, it is ensured that completely seal.

Specific embodiment
It should be noted that in the case where not conflicting, in the embodiment and embodiment in this utility model
Feature can be mutually combined.
Below with reference to the accompanying drawings and in conjunction with the embodiments describing this utility model in detail.
The present embodiment is related to a kind of multi-stage pipeline capping, as shown in figure 1, interior with right including pipeline is embedded at
The first closure part 1 that pipeline opening is blocked, being provided with the first closure part 1 can be engaging in pipeline outer peripheral face
On, engaging portion 2 to prevent the first closure part 1 from departing from pipeline.
As shown in figure 1, that the engaging portion 2 in the present embodiment includes being connected with the first closure part 1 and can clamping
Access Division 201 on pipeline outer peripheral face.It is provided with and the first closure on the first closure part 1 in the present embodiment
The limiting section 3 that concentrically line is arranged of portion 1, when the first closure part 1 is with pipeline grafting, the limiting section 3 can
It is connected to the outside of pipeline.Access Division 201 in the present embodiment includes what is arranged along the length direction of limiting section 3
Clamp 2011, and the free end in clamp 2011 is provided with snap fit 2012, is then provided with pipeline and is available for snap fit
2012 draw-in grooves 4 for snapping in.Clamp 2011 in the present embodiment is to arrange along the circumferencial direction of the first closure part 1
Multiple, such as it can be three, and the quantity of corresponding draw-in groove 4 is also three.
