Problems solved by technology

The existing insertion is often performed by manually pushing the equal-diameter tube. During the insertion process, the equal-diameter tube is prone to tilt and cannot advance uniformly, resulting in a large friction force between the iso-diameter tube and the sealing ring. Less friction on one side, the seal ring is easy to turn over
As a result, the sealing effect of the sealing ring is poor

Embodiment 1

[0044] An interface tool for pipe connection, such as figure 1 , including a fixed frame 1, a movable frame 2, a connecting column 4 and a manual hydraulic pump 3. The connecting column 4 is arranged between the fixed frame 1 and the movable frame 2, one end of the connecting column 4 is fixedly connected with the interactive furniture, and the other end is slidingly connected with the fixed frame 1, and the manual hydraulic pump 3 controls the sliding of the connecting column 4. The fixed frame 1 is connected with the pipe fittings, the movable frame 2 is connected with the pipeline, and the manual hydraulic pump 3 drives the movable frame 2 and the pipeline to move towards the fixed frame 1 through the connecting column 4, thereby inserting the pipeline into the pipe fitting.

[0045] Such as figure 1 , the movable frame 2 includes two semicircular movable hoops 8, and the two movable hoops 8 are connected by movable bolts 9. When the movable frame 2 is connected with the ...

Embodiment 2

[0052] A method of pipe connection using an interface tool such as figure 1 , using the interface tool for pipeline connection in Embodiment 1 to connect the pipelines. First of all, through the formula △L = L×α×△t, where: △L——pipe expansion and contraction (m), L——pipe length (m), △t——temperature difference (℃), α——line Expansion coefficient, using 9×10 -5 m / (m·℃), calculated for the expansion and contraction of the pipeline.

[0053] According to the calculation results, determine the socket amount and the length of the reserved expansion joints to prevent the pipe from being separated from the fittings. Draw a depth line on the pipe socket and mark it. When the pipe is inserted into the fitting and the depth line is flush with the end of the pipe, it means that the insertion depth is just right. According to the required length, the pipe is cut to the required length with a tool such as a cutter or cutter.

[0054] The pipe is angled 15° towards the end of the fitting t...

Abstract

The invention relates to the technical field of pipeline connection for construction, and discloses a connection tool used for connecting pipelines. The connection tool comprises a fixed frame, a movable frame and a manual hydraulic pump. The movable frame and the fixed frame are connected through a plurality of connecting columns which are evenly arranged in the circumferential direction. One endof each connecting column is fixedly connected with the movable frame, and the other end of each connecting column is slidably connected with the fixed frame. The manual hydraulic pump is connected with the connecting columns and is used for controlling sliding of the connecting columns. The connecting columns are evenly arranged between the fixed frame and the movable frame in the circumferential direction. The pipelines can move stably and uniformly in the moving process and are not prone to inclination, so that a sealing ring is prevented from turning, and the sealing performance of the sealing ring is ensured.

Description

technical field [0001] The invention relates to the technical field of building pipelines, in particular to an interface tool for pipeline connection and a pipeline connection method using the tool. Background technique [0002] Noise pollution has seriously affected people's daily life, and people expect to have a safe, healthy and environmentally friendly indoor space. The polypropylene super silent drainage pipe is a new type of environmental protection and energy-saving drainage pipe with the functions of quietness, heat resistance, chemical corrosion resistance, ultraviolet resistance and impact resistance. [0003] At present, the Chinese patent with the publication number CN107654772A discloses a flexible slide-in socket connection pipe, including an equal-diameter pipe and a socket, the small end of the socket is fixedly connected with the connecting end of the equal-diameter pipe, and a guide ring plate , the guide ring plate is placed at the big end of the socket,...
