[0002] In the oil and gas industry, gas valves are key devices used to control the flow of gas. These valves can open, close or regulate the flow of gas in the pipeline, and are essential to ensure the safe and efficient transportation of oil and gas; Ultra High-Speed ​​Valve (UHSV) refers to a valve system that works at extremely high speeds, and is usually used in applications that require fast response and frequent switching. This type of valve is designed to be able to complete the opening and closing action in a very short time, while withstanding the mechanical stress and wear caused by high speed.

[0003] Ultra-high speed gas valves usually need to have the following characteristics: High reliability: Able to maintain stable performance under frequent operations.

The blocking body components 3330 include a blocking body column group and a reset group. The blocking body column group includes a first blocking body 33301, a second blocking body 33302 and a blocking column 33303. The reset group includes a column 33304, a torsion spring 33305 and an elastic sheet 33306. The blocking column 33303 and the column 33304 are both fixedly arranged in the middle of the air holes 3332. The blocking column 33303 is located behind the column 33304. The torsion spring 33305 is sleeved on the outer ring of the column 33304.

The first blocking body 33301 and the second blocking body 33302 are respectively located on both sides of the blocking column 33303 and are rotatably connected to the blocking column 33303. The upper and lower sides of the second block body 33302 are in seamless contact with the hole wall of the air hole 3332. The first block body 33301 and the second block body 33302 are respectively fixedly connected to one antenna of the torsion spring 33305. One end of the elastic sheet 33306 is fixedly connected to the inner surface of the first block body 33301, and the other end is fixedly connected to the inner surface of the second block body 33302. The inner side surfaces of the first block body 33301 and the second block body 33302 are fixed with triangular pyramid strips 33307. The end surfaces of the triangular pyramid strips 33307 facing the blocking block 3339 are inclined surfaces. The end surfaces of the first block body 33301 and the second block body 33302 facing the blocking block 3339 are fixed with triangular extrusion blocks 33308. When the second transmission assembly drives the air plug part 34 to move forward, the air plug part 34 pushes the movable block 3337 to turn to the valve body 3331, and the blocking block 3339 extends into the corresponding air hole 3332, and the blocking block 3339 contacts and squeezes the first block 33301 and the second block 33302. In this process, the triangular extrusion block 33308 is stuck in the notch 33391, and the blocking block 3339 is slowly opened from the notch 33391. Since the first block 33301 and the second block 33302 are both inclined in the initial state, as the blocking block 3339 continuously squeezes the first block 33301 and the second block 33302 and pushes the first block 33301 301 and the second stopper 33302 rotate around the column 33304, the torsion spring 33305 opens, and the elastic sheet 33306 stretches. As the first stopper 33301 and the second stopper 33302 continue to expand, their ends will be in close contact with the inner walls on the left and right sides of the air hole 3332, forming a compression seal on the inner walls on the left and right sides of the air hole 3332, and as the blocking block 3339 continues to squeeze deeper, its two ends will enter into the triangular area formed by the expansion of the first stopper 33301 and the second stopper 33302, and enter the position between the conical ends of the two triangular pyramid strips 33307 after passing through the triangular end face of the triangular pyramid strip 33307, and During the continuous squeezing of the block 3339, the triangular pyramid bar 33307 will also push the block 3339 away from the notch 33391, and the upper and lower end faces of the pushed-up block 3339 will form a tight and seamless contact with the upper and lower side walls of the pore 3332, forming a compression seal on the upper and lower inner walls of the pore 3332, thereby forming a full range of compression seal contact with the pore 3332, and the air valve is closed, effectively ensuring the high sealing of the pore 3332. Moreover, since the first block body 33301, the second block body 33302 and the block 3339 are expanded and squeezed with the hole wall of the pore 3332 only after being acted upon by an external force, The pressure is pressed to achieve sealing. This design does not have obvious mobile friction, which will effectively reduce the wear of the first block body 33301, the second block body 33302 and the blocking block 3339, ensuring high sealing performance under long-term use. When the second transmission assembly drives the air plug part 34 to move backward, the movable block 3337 rotates away from the valve body 3331, and the blocking block 3339 leaves the air hole 3332. Under the joint action of the rebound force of the torsion spring 33305 and the elastic sheet 33306, the first block body 33301 and the second block body 33302 rotate towards each other to restore, releasing the contact with the wall of the air hole 3332, so that the air hole 3332 is unblocked, the air valve is opened, and the gas can be discharged through the exhaust port 334.

[0025] The first transmission assembly includes a cushion block 21, a plurality of limit rings 22 and a connecting shaft 23. The cushion block 21 is fixed on the base 11. In this embodiment, two limit rings 22 are preferably used to limit the connecting shaft 23 at the front and rear ends so that it can move in the same vertical plane.

The connecting shaft 23 crosses the limit rings 22 and is slidably connected to the limit rings 22. The bottom end of the connecting shaft 23 is rotatably connected to the eccentric wheel 14. When the eccentric wheel 14 rotates, it drives the bottom end of the connecting shaft 23 to reciprocate along the elliptical orbit, pulls the limit ring 22 upward or presses it downward, and the limit ring 22 limits the connecting shaft 23 to move in the same vertical plane, so that the top end slides back and forth, pulling the slider 24 to slide back and forth.

One end of the spring sheet 3338 is fixedly connected to the valve body 3331, and the other end is against the movable block 3337. When the movable block 3337 rotates around the valve body 3331 and enters the groove 3336, the air hole 3332 is blocked and the spring sheet 3338 is squeezed. When the spring sheet 3338 rebounds, it pushes the movable block 3337 to leave the groove 3336, and the air hole 3332 is opened.

[0031] The gas plug portion 34 includes a gas plug 341, a plurality of gas blocks 342 and a plurality of stop blocks 343. The gas plug 341 is located in the inner cavity 332. The top end of the push rod 26 is fixedly connected to the bottom surface of the gas plug 341.

When the second protrusion 3333 is located in the third guide groove 3421 and the third protrusion 3422 is located in the second guide groove 3334, the gas block 342 can slide back and forth along the valve portion 333. When the gas block 342 slides forward along the valve portion 333 and blocks the air hole 3332, the air valve is closed. When the gas block 342 slides backward along the valve portion 333 and leaves the air hole 3332, the air valve is opened.

[0033] Start the power source 12, and the power source 12 drives the eccentric wheel 14 to rotate through the connecting rod 13. The rotating eccentric wheel 14 drives the connecting shaft 23 to slide forward and backward along the limiting ring 22, and the connecting shaft 23 pulls the slider 24 to slide forward and backward on the bottom plate 25. When the slider 24 slides forward, the push rod 26 is pushed into the cylinder part 33, and when the slider 24 slides backward, the push rod 26 is pulled out of the cylinder part 33; when the push rod 26 is pushed into the cylinder part 33, the gas plug part 34 is pushed by the push rod 26 to move toward the valve part 333, so that the second protrusion 3333 enters the corresponding third guide groove 3421, and the third protrusion 3422 enters the corresponding second guide groove 3334, thereby reducing the gap between the gas block 342 and the valve part 333, increasing the sealing between the two, and preventing gas from The air block 342 overflows from the gap between the air block 342 and the valve part 333, and the air block 342 slides forward along the valve part 333. When the air block 342 contacts the movable block 3337, the air block 342 presses the movable block 3337 toward the valve body 3331, so that the movable block 3337 rotates around the valve body 3331 and enters the groove 3336 to block the air hole 3332. The spring sheet 3338 is squeezed and deformed. As the air block 342 moves forward, the valve body 3331 presses against the block 343, and the sealing strip 3335 enters the sealing port 3431 to block the gap between the block 343 and the valve part 333, thereby improving the sealing of the two. The movable block 3337 completely enters the groove 3336, and the air hole 3332 is completely blocked by the movable block 3337. In this process, the air block 342 is The block 3339 extends into the corresponding air hole 3332, and the block 3339 will contact and squeeze the first block body 33301 and the second block body 33302. In this process, the triangular extrusion block 33308 will be stuck in the notch 33391, and the block 3339 will slowly open from the notch 33391. Since the first block body 33301 and the second block body 33302 are both inclined in the initial state, as the block 3339 continuously squeezes the first block body 33301 and the second block body 33302 and pushes the first block body 33301 and the second block body 33302 to rotate around the column 33304, the torsion spring 33305 opens, and the elastic sheet 33306 stretches. As the first block body 33301 and the second block body 33302 continue to expand, the ends of the torsion springs 33305 and the elastic sheet 33306 will expand. The block 3339 is in close contact with the inner walls on the left and right sides of the air hole 3332, forming a compression seal on the inner walls on the left and right sides of the air hole 3332. As the block 3339 is continuously squeezed, its two ends will enter the triangular area formed by the expansion of the first block 33301 and the second block 33302, and enter the position between the conical ends of the two triangular pyramid strips 33307 after passing through the triangular end face of the triangular pyramid strip 33307. In the process of continuous squeezing of the block 3339, the triangular pyramid strip 33307 will also open the block 3339 from the notch 33391. The upper and lower end faces of the opened block 3339 will form a close and seamless contact with the upper and lower side walls of the air hole 3332, forming a compression seal on the upper and lower side walls of the air hole 3332.Thereby, a compressive sealing contact is formed on the air hole 3332 in all directions, which effectively ensures the high sealing of the air hole 3332. The gas in the air storage box 31 cannot enter the inner cavity 332 through the air hole 3332, and the gas stops being discharged. Moreover, since the first block body 33301, the second block body 33302 and the block 3339 are expanded only after being acted upon by an external force and form an extrusion with the hole wall of the air hole 3332 to achieve sealing, this design does not have obvious mobile friction, which will effectively reduce the first block body 33301, The wear of the second stopper 33302 and the block 3339 ensures high sealing performance under long-term use; when the push rod 26 is pulled out of the cylinder part 33 and the gas block 342 leaves the movable block 3337, the pressure of the gas block 342 on the movable block 3337 disappears, the spring sheet 3338 rebounds, and pushes the movable block 3337 to rotate around the valve body 3331, leaving the groove 3336, and the air hole 3332 is opened. At this time, the gas in the air storage box 31 can enter the inner cavity 332 through the air hole 3332, and then be discharged to the outside of the device through the exhaust port 334.
