Abstract
(B, ) the utility model discloses an auxiliary device convenient to pipeline intercommunication department closes water and checks and accepts, including casing head and the fixed fastener that sets up at the pipeline tip, a casing head tip seals another tip and is provided with activity card portion, activity card portion and both have lock -out state or unblock state the fastener. Because the utility model discloses a with the fixed fastener locking casing head of pipeline, can improve the security performance in the use, and casing head easy dismounting, used repeatedly is rateed highly. (B, )
Description
Technical field
The utility model relates to building field, particularly a kind of supplementary unit be convenient to pipeline communication place and close water and check and accept.
Background technology
In engineering, newly-built sewer line all needs the airtight performance of testing pipes, carries out closed-water test, and current way normally adopts air bag to block one end of pipeline, then toward water filling in pipeline, thus whether testing pipes leaks. But air bag is easily walked by the current punching of elevated pressures, thus there is potential safety hazard, and air bag cost is higher, easily damages, and repeat usage is not high.
Summary of the invention
The purpose of this utility model is to provide a kind of supplementary unit be convenient to pipeline communication place and close water and check and accept.
For achieving the above object, the technical solution adopted in the utility model is: a kind of supplementary unit be convenient to pipeline communication place and close water and check and accept, comprise casinghead and it is fixedly installed on the card part of pipe end, described casinghead one end is closed the other end and is provided with movable card division, and described movable card division and described card part have locking state or released state.
Preferably, described movable card division comprises the rotation axis being rotationally connected with described casinghead and the cover portion being arranged on described rotation axis, and described cover portion can cooperatively interact with described card part.
Preferably, described card part is symmetrically arranged with two, lays respectively at the upper and lower part of described pipeline.
Preferably, the inwall of described casinghead and described pipeline outer wall at least one be provided with sealing-ring.
Owing to technique scheme is used, the utility model compared with prior art has following advantage:
Owing to the utility model is by the card part lock collar head fixing with pipeline, it is possible to improve the safety performance in using, and casinghead easy accessibility, repeat usage height.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model schematic diagram;
Accompanying drawing 2 is pipe end schematic diagram;
Accompanying drawing 3 is casinghead schematic diagram.
In above accompanying drawing: 1, pipeline; 2, casinghead; 21, rotation axis; 22, cover portion; 3, card part; 4, sealing-ring.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described:
Embodiment one: shown in FIGS 1-3, a kind of supplementary unit be convenient to pipeline communication place and close water and check and accept, comprise casinghead 2 and it is fixedly installed on the card part 3 of pipeline 1 end, described casinghead 2 one end is closed the other end and is provided with movable card division, and described movable card division and described both card parts 3 have locking state or released state.
Described movable card division comprises the rotation axis 21 being rotationally connected with described casinghead 2 and the cover portion 22 being arranged on described rotation axis 21, and described cover portion 22 can cooperatively interact with described card part 3.
Described card part 3 is symmetrically arranged with two, lays respectively at the upper and lower part of described pipeline 1.
The inwall of described casinghead 2 and described pipeline 1 outer wall at least one be provided with sealing-ring 4.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this. All equivalences done according to the utility model spirit change or modify, and all should be encompassed within protection domain of the present utility model.
