Water supply and drainage pipe head connecting mold, method, product and preparation method

Abstract

The invention discloses a water supply and drainage pipe head connecting mold, which is used for filling, flattening and butting water supply and drainage pipe heads, and comprises an injection mold detachably connected to the end part of the water supply and drainage pipe head. When the injection mold is connected to the end of the water supply and drainage pipe head, the injection mold is used for injection molding filling and leveling, so that the end of the water supply and drainage pipe head is filled and leveled, and the connector is obtained. And the butt welding mold is arranged on the injection mold, the side wall of the butt welding mold is connected with the side wall of the injection mold, and the butt welding mold is used for conducting butt joint connection on the drainage pipe heads subjected to injection molding through the injection mold. The device is simple in overall structure, convenient to disassemble and suitable for connection of various water supply and drainage pipes of buried water pipes, and has a remarkable practical effect. The invention further discloses a use method of the water supply and drainage pipe head connecting mold, a product based on the water supply and drainage pipe head connecting mold and a preparation method of the product based on the water supply and drainage pipe head connecting mold.

Description

technical field [0001] The invention relates to the technical field of buried water supply and drainage pipe connection, in particular to a water supply and drainage pipe pipe head connection mold, method, product and preparation method. Background technique [0002] Water supply projects have become an important infrastructure for cities and industrial and mining enterprises. It must ensure that sufficient water, qualified water quality, and sufficient water pressure are used to supply domestic water, production water and other water. Water supply and drainage pipes have higher requirements. [0003] In the process of buried construction of water supply and drainage pipes, it is necessary to connect multiple pipes to meet the needs of long-distance water supply and drainage. At present, the methods of connecting pipes include welding, welding, etc., specifically: directly connect the sockets of the two pipes to be connected with the sockets, and seal them with rubber; or m...

Problems solved by technology

However, the connection end faces of most pipes are not neat. When connecting with the connector or another pipe during the connection process, the connection will be incomplete. During the long-term water delivery process, water seepage and water leakage will occur. If the sewage pipe Water leakage will pollute the underground soil environment; if it is a water supply pipe, long-term leakage of water will waste water and cause hidden dangers of ground subsidence; the most important thing is that the pressure in the water supply pipe is high. When encountering the water hammer effect, two The joints of the pipes are difficult to withstand greater pressure and are damaged, causing major safety hazards

[0004] The above method of connecting the pipes is prone to leakage at the joints of the pipes, causing pollution, and it is difficult to withstand the impact of high pressure and be destroyed, which has potential safety hazards
