Description

Technical Field

[0001] This invention relates to the field of single-seat bidirectional sealing track ball valve technology, specifically a novel valve seat for a single-seat bidirectional sealing track ball valve. Background Technology

[0002] A single-seat valve refers to a valve with only one valve body and valve core. A bidirectional sealing ball valve is a type of ball valve. Ball valves and gate valves belong to the same category of valves, the difference being that the closing element is a ball. The ball rotates around the valve body's centerline to open and close the valve. Bidirectional sealing ball valves are mainly used in pipelines for shut-off, distribution, and changing the flow direction of media. Existing single-seat bidirectional sealing ball valves are prone to contamination and blockage of the ball core during use, which can affect their normal operation. Furthermore, most existing single-seat bidirectional sealing ball valves only have one actuation mechanism, and when the actuation mechanism malfunctions, it is inconvenient to open and close the device. To address these issues, improvements to existing equipment are necessary. Summary of the Invention

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-6 The present invention provides a technical solution: a novel valve seat for a single-seat bidirectional sealing ball valve, such as... Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the main mechanism 1 includes a valve body 101, a ball 102, a through hole 103, a valve stem 104, a first gear 105, a base 106, a reinforcing column 107, a sealing gasket 108, and a rubber ring 109. The ball 102 is disposed inside the valve body 101, and sealing gaskets 108 are symmetrically arranged on both sides of the ball 102. A rubber ring 109 is disposed on the outer side of the sealing gasket 108.

The connecting rod 202 is provided on the rotating shaft 201, and the end of the connecting rod 202 away from the rotating shaft 201 is connected to the scraper 203. The cleaning mechanism 2 facilitates the cleaning of the inner wall of the through hole 103, thereby preventing dirt from entering. To prevent contamination and blockage of the through hole 103, ensuring normal operation of the device, a valve stem 104 is connected to the top of the ball 102.

The end of the rack 304 away from the piston head 302 passes through the left side of the air storage box 301 and is located inside the soundproof enclosure 6. A stop block 305 is provided on the rack 304. The rack 304 is located on the first gear 105. The rack 304 is located on the rear side of the first gear 105, and the rack 304 meshes with the first gear 105. Simultaneously, the first gear 105 meshes with the second gear 401. Both the first gear 105 and the second gear 401 serve a transmission function. The second drive mechanism 4 includes a second gear 401, a first drive shaft 402, a belt shaft 403, a drive belt 404, a second drive shaft 405, a connecting cover 406, a connecting block 407, a limiting hole 408, a motor 409, a hydraulic cylinder 4010, and a support plate 4011. The second gear 401 is located on the front side of the first gear 105, and the second gear 401...

Both the first drive shaft 402 and the second drive shaft 405 are provided with belt shafts 403, and the belt shafts 403 are connected by a drive belt 404. A connecting cover 406 is provided at the bottom of the second drive shaft 405, and a locking mechanism 5 is provided on the connecting cover 406. The locking mechanism 5 includes a fixing plate 501, an electric telescopic rod 502, and a locking block 503.

Connecting block 407 is provided below connecting cover 406. Locking block 503 engages with limiting hole 408 on connecting block 407. Locking block 503 facilitates tight connection between cover 406 and connecting block 407. Connecting block 407 is connected to the output end of motor 409. The bottom of motor 409 is connected to support plate 4011 through hydraulic cylinder 4010. Support plate 4011 is fixedly connected to the front inner wall of soundproof cover 6.

[0031] Working Principle: When using this new type of single-seat bidirectional sealing track ball valve, first connect the left and right ends of the valve body 101 to the pipeline, and then connect the pneumatic mechanism to the air inlet 303. When the device needs to be opened, the operator can control the pneumatic mechanism to fill the air storage tank 301 with air. The gas entering the air storage tank 301 will push the piston head 302 and rack 304 to the left. The leftward movement of the rack 304 will push the first gear 105 to rotate the ball 102, thereby exposing the through hole 103. The flow medium entering the valve body 101 will flow out through the through hole 103. At the same time, the flowing medium can push the rotating shaft 201 and scraper 203 inside the through hole 103 to rotate. The rotating scraper 203 can scrape off the impurities attached to the inner wall of the through hole 103, thereby preventing them from clogging the through hole 103. When the pneumatic mechanism malfunctions, the operator can control the hydraulic cylinder 4010 to push the motor 409 and the connecting block 407 upwards until the connecting block 407 engages in the connecting cover 406. Then, the electric telescopic rod 502 pushes the locking block 503 into the connecting cover 406 and engages it in the limiting hole 408. Immediately afterwards, the motor 409 drives the second drive shaft 405 to rotate through the connecting block 407 and the connecting cover 406. The second drive shaft 405 drives the first drive shaft 402 and the second gear 401 at its bottom to rotate through the drive belt 404. The second gear 401 pushes the first gear 105 to drive the ball 102 to rotate, thereby opening the device. This completes all the work.
