Technical Field
The invention belongs to the field of municipal pipelines, and particularly relates to a water pipe plug and a matching device thereof, which are mainly used for low-pressure or non-pressure water supply and drainage pipeline plugs and maintenance.
Background
In the existing water supply and drainage engineering, when a pipeline is damaged or broken, particularly when the pipeline needs to be reconnected, a valve is required to be closed at the upstream of a joint and then maintained, but other branches or areas are caused to be water-cut off, and sometimes a large amount of time is required to find the upstream valve, so that loss and inconvenience are caused.
Disclosure of Invention
Aiming at the problems in the prior art, the technical scheme adopted by the invention for solving the problems in the prior art is as follows:
the utility model provides a water pipe end cap and supporting device which characterized in that: the end cap includes the valve inside, links up the gasbag as an organic whole with the valve inside, and the valve inside link up the gasbag, and the gasbag both ends are equipped with a plurality of supports respectively, are connected through spring A between support one end and the valve inside, the kit is for being used for the anchor clamps that take out the end cap from the pipeline, anchor clamps are including pushing down the handle and connecting the handle, push down the handle bottom and connect the movable rod, and the movable rod bottom is connected and is provided with the thimble, and connecting handle middle part trompil is equipped with the sleeve, and the sleeve cover is established on the movable rod, and the connecting handle bottom is equipped with the soldering lug of a plurality of perpendicular settings, soldering lug bottom swing joint clamping piece, is connected through spring B between the.
The upper end and the lower end of the air bag are respectively provided with three supports which are uniformly arranged in the circumferential direction, and the distance between the inflating end of the valve core and the near-end support is more than 3 cm.
The thimble needle cap is concave inwards, is 2mm larger than the size of the valve core gas needle, and can just wrap the gas needle.
The inner diameter of the sleeve is 2-4mm larger than the outer diameter of the movable rod, so that the movable rod can freely move up and down in the sleeve.
The soldering lug is connected with the clamping piece through a hinge.
The clamping pieces are four, and the bottom ends of the four clamping pieces are provided with hooks bent inwards.
The invention has the following advantages:
1. the device has simple structure, easy manufacture and simple application method, is suitable for temporary plugging of the pipeline by inflating and expanding the air bag, and is suitable for connection and maintenance of the pipeline, in particular for hot melting connection and maintenance of the PVC pipeline by a suitable application method;
2. the plug device is easy to take out by matching with a special clamp, and the device can be repeatedly used;
3. the pipeline can be directly connected and maintained through temporary plugging, so that the phenomenon that other branches are cut off water due to the fact that an upstream valve stops water is avoided, and economic loss is caused;
4. under the condition that the upstream valve is not clear, through temporary plugging at a damaged point, manpower, material resources and time for searching the upstream valve switch are saved, the cost is reduced, and the benefit is improved;
5. the device gasbag sets up upper and lower triangular supports, and through the fixed principle of triangle, makes the valve inside placed in the middle, and convenient follow-up valve inside of finding is installed.

Detailed Description
Referring to fig. 1-5, the pipe plug includes a
The
In addition, a matched clamp is used for conveniently taking out the plug device after hot melting (or other connection) construction, and the plug device comprises a
The working process is as follows:
the PVC pipeline is maintained under the condition of not closing an upstream valve, and is explained by combining the attached drawings:
(1) as shown in fig. 1, the original pipeline is damaged or broken, and water leakage occurs, so that the original pipeline cannot be repaired, and the original pipeline needs to be cut open to be reconnected.
(2) After the original pipeline is cut open, the plug device is placed into the water
(3) After water flow is blocked, a pipeline cut is trimmed, cleaned and dried, and a
(4) After the last step is finished, the
(5) And closing the ball valve switch and connecting the pipeline at the other end.
The protective scope of the present invention is not limited to the above-described embodiments, and it is apparent that various modifications and variations can be made to the present invention by those skilled in the art without departing from the scope and spirit of the present invention. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
