[0002] A control valve, also known as a regulating valve, is a final control element in industrial automation process control. It receives control signals from a regulating control unit and uses power to change process parameters such as flow rate, pressure, temperature, and level. It generally consists of an actuator and a valve body. Based on stroke characteristics, control valves can be divided into linear stroke and rotary stroke valves; based on the power source of their actuators, they can be divided into pneumatic control valves, electric control valves, and hydraulic control valves; and based on their function and characteristics, they can be divided into linear characteristic, equal percentage characteristic, and parabolic characteristic valves.

[0003] Existing flow control valves are prone to leakage due to insufficient sealing at their connection points, which can damage the valve. There is an urgent need for a flow control valve with a leak-proof mechanism to solve this problem. Utility Model Content

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-7 This utility model provides a technical solution: a regulating valve with a leak-proof mechanism, including a valve body 1 and a leak-proof component 2. The input and output ends of the valve body 1 are integrally formed with flange plates 3. The leak-proof component 2 includes a circular ring 20, a first semi-circular sealing ring 22, and a second semi-circular sealing ring 23. U-shaped plates 24 are fixedly connected to the left and right sides of the circular ring 20. Knobs 27 are rotatably installed on the outer side of the vertical ends of the two U-shaped plates 24. Guide grooves 200 are provided on the left and right sides of the circular ring 20. Threaded blocks 25 are slidably installed inside the two guide grooves 200. Screws 26 are fixedly connected to the inner ends of the two knobs 27. The two screws 26 are threadedly connected to the two threaded blocks 25. Slots 201 are provided at the upper and lower ends of the left side of the first semi-circular sealing ring 22. Insert plates 202 are fixedly connected to the upper and lower ends of the right side of the second semi-circular sealing ring 23. This design solves the problem that existing flow regulating valves, due to insufficient sealing effect, are prone to leakage from the connection points of the flow regulating valve, thus causing damage to the flow regulating valve.

[0023] In the first embodiment of this utility model: the first semicircular sealing ring 22 and the second semicircular sealing ring 23 are respectively fixedly connected to the ends of the two threaded blocks 25. By fixing the first semicircular sealing ring 22 and the second semicircular sealing ring 23 to the ends of the two threaded blocks 25, it is convenient to move the first semicircular sealing ring 22 and the second semicircular sealing ring 23 through the two threaded blocks 25. The two knobs 27 are respectively provided with positioning holes 203 through their sides, which facilitates the insertion of threaded rods 28. Connecting rods 21 are fixedly connected to the upper and lower ends of the right side of the ring 20. Two U-shaped plates 24 have magnetic plates 29 fixedly attached to their upper outer sides at their vertical ends. Threaded rods 28 are slidably inserted and installed above each magnetic plate 29. Magnetic rings 204 with opposite magnetic properties to the magnetic plates 29 are fixedly sleeved on the annular sides of each threaded rod 28. Nuts 205 are screwed onto the threads at the lower ends of each threaded rod 28. The magnetic attraction between the magnetic plates 29 and the magnetic rings 204 facilitates temporary limiting of the threaded rods 28. Two leak-proof components 2 are provided, with multiple connecting rods 21 fixedly connected to the input and output ends of the valve body 1, respectively.

[0024] As a second embodiment of this utility model: In use, first separate the two nuts 205 of the left anti-leakage component 2 from the two threaded rods 28, then pull up the two threaded rods 28, so that the two magnetic plates 29 and the two magnetic rings 204 are magnetically attracted. At this time, the two threaded rods 28 disengage from the two positioning holes 203. Then rotate the two knobs 27, which in turn drives the two lead screws 26 to rotate, so that the two threaded blocks 25 drive the first semi-circular sealing ring 22 and the second semi-circular sealing ring 23 to slide along the guide groove 200, so that the two insert plates 202 disengage from the two slots 201. The right anti-leakage component 2 is operated in the same way. Then, the external pipe can be connected to the two flange plates 3 through the flange. The flange and flange plate 3 mentioned here With the same specifications, the two knobs 27 are then rotated in the opposite direction, causing the two threaded blocks 25 to drive the first semi-circular sealing ring 22 and the second semi-circular sealing ring 23 to slide and reset along the guide groove 200. When the two insert plates 202 are inserted into the two slots 201, the first semi-circular sealing ring 22 and the second semi-circular sealing ring 23 press tightly against the connection between the flange plate 3 and the external flange to seal it. At this time, the two positioning holes 203 are aligned with the two threaded insert rods 28. The two threaded insert rods 28 are pressed down so that the two threaded insert rods 28 pass through the two positioning holes 203. Finally, the two nuts 205 are screwed onto the lower ends of the two threaded insert rods 28 to complete the limiting of the two knobs 27. The restoration operation of the other anti-leakage component 2 is also set according to the above steps.
