Description

TECHNICAL FIELD

[0001] The utility model belongs to pipeline tee joint technical field relates to a pipeline joint with double leakproof structure. BACKGROUND

[0002] The shortcomings of the existing pipeline tee joint in the aspect of leakproof resistance under liquid pressure loss mainly lie in its structural design. These joints usually rely on sealing elements such as O-rings or gaskets to achieve sealing, but in the case of liquid pressure loss, the sealing effect will be greatly reduced due to the lack of sufficient pressure to extrude the sealing element, resulting in liquid leakage. The tee joint may not have considered the problem of reverse flow when the liquid pressure is lost in the design, so under the condition of pressure loss, the liquid may flow reversely along the pipeline, causing the liquid in the system to flow back, affecting the normal operation of the system.

[0003] The root cause of these shortcomings lies in the fact that the design of traditional tee joints does not have a special leakproof and flow-resistant design for the pressure loss state, but relies more on the sealing performance under normal working pressure. In the pressure loss state, the sealing element cannot provide sufficient resistance to stop the flow of liquid, resulting in leakage and backflow.

[0004] The conventional methods include increasing additional valves to control liquid flow or using higher-level sealing materials and designs to improve sealing performance. However, the disadvantages of these methods are that they increase the complexity of the system, increase the cost, and may introduce new failure points. Although the addition of valves can control the flow of liquid, in the case of pressure loss, the valves themselves may fail to close normally, thus failing to effectively prevent leakage. While the use of higher-level sealing materials and designs can improve sealing performance, it also increases costs, so there is an urgent need for a pipeline joint with double leakproof structure to solve the above problems.
