Description

Technical Field

[0001] The invention relates to the technical field of urban water supply industry, in particular to a novel stop pipe quick connector. Background Art

[0002] The urban water supply system is a component of urban public utilities. The urban water supply system planning is a component of the city's overall planning. The urban water supply system is usually composed of water sources, water pipelines, water plants and water distribution networks. After taking water from the water source, it is sent to the water plant through the water pipeline for water quality treatment. The treated water is pressurized and sent to users through the water distribution network.

[0003] Chinese patent number CN112524358B provides a coupling device for connecting a pipe to another pipe or a connector. The coupling device includes a connector body having an open end for receiving the free end of the pipe, the connector body including one or more holes, the one or more holes defining a plurality of channels or bores from the front surface of the connector body through a portion of the connector body to a radial inner surface, the radial inner surface being positioned near the first metal element in use, wherein the connector body is configured so that a force-applying member can be inserted into the channel or bore to apply force to the first metal element so as to induce axial movement of the first metal element in the direction of the metal sealing surface in use. The present invention also provides a method for connecting a pipe to another pipe or a connector.

[0004] When installing control valves, metering equipment or connecting branches on cast iron, steel or PE pipes, existing connectors have the following technical and structural defects:

[0005] 1. The existing screw-stop quick connector has insufficient locking force. The set screws can easily damage the pipeline. It is not suitable for PE pipes and cannot effectively control the axial rotation of the installed valves and metering equipment. The installed equipment may drive the rubber ring of the connector to rotate, causing the pipeline seal to be damaged and leaking.

[0006] 2. Existing locking ring quick connectors have the following defects:

[0007] (1) The locking ring has a narrow matching range of pipe diameters. In actual applications, the locking ring cannot be installed on old pipes with different outer diameter deviations.

[0008] (2) The double-layer clamping device of the rubber sealing ring and the locking ring has a complex structure, high requirements for on-site installation, and a long operation time.

[0009] (3) The contact surface between the locking ring and the pipeline is too small. When installing large valves or metering equipment with a large center of gravity offset, or when external force is applied, the installed equipment may cause the rubber ring of the connector to rotate, which cannot completely solve the risk of pipeline seal damage and leakage caused by the rotation of the rubber ring.

[0010] (4) The contact surface of the rubber sealing ring and the clamping ring is too small, and the rubber sealing ring is often damaged in actual applications.

[0011] (5) The sealing cavity of the sealing ring is not deep enough, and the rubber ring may deviate in actual application. Summary of the invention
