Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and specifically relates to a valve with a high sealing structure. Background Technology

[0002] A valve is a mechanical device used to control the flow of fluids in pipelines. It is widely used in industrial, civil, and public utilities. It regulates and controls parameters such as flow rate, pressure, and temperature of fluids (e.g., liquids, gases, steam) by changing the cross-sectional area or direction of the passage. Sealing performance is a crucial parameter in valve operation, determining its effectiveness in isolating the fluid. However, most common valves rely on a single on / off control structure for sealing. During fluid transport, the sealing area is constantly subjected to fluid erosion. Wear and tear during later control operations can lead to poor sealing, insufficient sealing effectiveness, frequent maintenance, and impacts actual fluid transport. Furthermore, decreased sealing performance may result in incomplete fluid isolation, leading to leakage.

[0003] In summary, valves with insufficient sealing performance present some problems during use. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content

[0013] The connecting block is embedded in the inner side of the connecting groove and the positioning stud is screwed into the inner side of the positioning threaded hole for fixed connection. A set of limiting plates for limiting the rotation of the control wheel are fixedly connected to both the left and right ends of the outer side of the control seat. When the control wheel is not in use, it is disengaged from the positioning, so that the wheel body is placed between the two sets of limiting plates, which can avoid rotation control in case of accident.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by adding a valve body and a control wheel, a set of sealing components is installed in the valve center. The fluid flows in through the inlet pipe and passes through the buffer baffle to reduce the impact force and prevent direct impact on the sealing plunger.
