Embodiment 1

[0021] It is composed of two pipes directly connected:

[0022] Add a rubber ring to the two connecting pipe joints, and embed the rubber ring directly into the joint of the pipe diameter; there is a groove in the socket of the pipe joint, and a groove outside the socket of the pipe joint. A rubber ring is installed in the groove of the mouth, and the socket of the connecting pipe is inserted into the reaming socket of another connecting pipe to form a flexible connection.

Embodiment 2

[0024] Add a hoop for two tubes:

[0025] Add a rubber ring to the hoop-shaped interface where the two connecting pipes are inserted to connect, and embed the rubber ring directly into the interface of the pipe diameter; there is a groove in the interface, and a groove is provided outside the insertion interface of the two connecting pipes. A rubber ring is installed in the groove of the interface, and the sockets of the two connecting pipes are relatively inserted into a hoop-shaped interface to form a flexible connection.

[0026] The invention provides an improvement method for a flexible interface UPVC (rigid polyvinyl chloride) water supply pipeline conforming to national standards and suitable for modern engineering.

[0027] A rubber ring is used to improve the original flexible connection at the connection of two sets of pipelines, and a new type of flexible interface is established. The flexible interface rubber ring can resist earthquakes very well, and effectively ...

Abstract

The invention provides a flexible pipe connector for underground hard plastic water supply pipe, relating to a constructional member. A rubber ring is added between two connecting pipe connectors for connection, the rubber ring is directly embedded into the connection position of pipe; the pipe bell of the pipe connector thereof is internally provided with a groove, the socket of the pipe connector is externally provided with a groove, the grooves of the pipe bell and the socket are internally provided with a rubber ring, and the socket of the pipe connector is inserted into the underreamed pipe bell of another pipe connector to be in flexible connection. The invention provides a flexible connector UPVC water supply pipeline improvement method which accords with national regulation and isapplicable to modern project. The flexible connector rubber ring can well resist earthquake and effectively reduces horizontal and vertical stresses born by underground pipeline under the action of earthquake. The connector can effectively enhance compatness of connector, can improve overall pulling test strength and can improve leakage resistance. Meanwhile corrosion resistance of pipeline can be improved, and safety and reliability of building can be enhanced.

Description

technical field [0001] The invention relates to a building component, in particular to a flexible pipe joint of a rigid plastic water supply pipe used underground. Background technique [0002] At the beginning of the mid-1970s, after the San Fernando earthquake, people began to realize the importance of lifeline earthquake engineering. They felt that the previous earthquake engineering was too focused on structures such as buildings, bridges, and dams, and began to treat lifelines from a systematic point of view. Earthquake engineering research. In 1971, Martin Duke investigated the engineering earthquake damage of San Fernando's urban power transmission system, transportation system, water supply system and gas system caused by the earthquake, and the impact of these engineering system earthquake disasters (including secondary disasters caused by earthquakes) on urban functions. After the impact, it is believed that these engineering systems are of special importance to t...
