Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valve to the various valves used in extremely complex automatic control systems.

[0003] After searching, the patent with the authorization announcement number CN219510148U proposes a valve axial positioning structure, including a main body, the upper and lower ends of the main body are fixedly connected with flange rings, the front and rear ends of the main body are provided with fixed plates, two of the fixed plates are provided, the front sides of the right ends of the two fixed plates are fixedly connected with fixed columns, four of the fixed columns are provided, the fixed columns are fixedly connected with fixed rods, the fixed columns are provided with valve mechanisms, and the interior of the main body is provided with blocking mechanisms. The valve axial positioning structure rotates the threaded rod to the right by turning the valve, pulling the arc plate to move to the right, and the circular baffle is pushed to rotate when the arc plate moves, and the return rod returns to the closing port, thereby using less force to block the water from entering the closing port, saving more effort and improving practicality. By using the movable connection between the closing port and the circular baffle, the circular baffle can well block the closing port, thereby preventing water from flowing out of the gap, improving practicality. The following problems exist in this technical solution:

[0004] When in use, the flow of water can be easily controlled by the valve mechanism. However, due to the poor stability of the valve and the external vibration transmitted to the valve, the valve will shake, which will drive the valve mechanism to shake slightly as a whole, thus causing the connection between the valve mechanism and the main body to loosen, which is prone to water leakage and reduces the use effect.

[0005] In view of the above problems, the utility model document proposes a valve. Utility Model Content
