When the servo motor 106 is started, the threaded screw 110 is driven to rotate, and the movable valve block 111 is driven to move up and down, and then the connecting bolt 125 and the valve cover 126 are moved up and down, and the limit column 124 can block the moving spacing range of the valve cover 126, the lower end of the valve cover 126 is inserted on the valve sleeve 127, and the through hole 134 is provided inside the valve cover 126. The movement can release or close the oil and gas flowing out of the valve sleeve 127, and the valve sleeve 127 is installed at the upper end of the oil and gas steel pipe 131. The oil and gas flow to the inside of the oil and gas steel pipe 131 through the oil and gas pipeline, and then flow out of the valve sleeve 127 from the inside of the oil and gas steel pipe 131. The lower end of the first valve body 104 is connected and fixed to the second flange 103 by welding, and a sensor 101 is installed on one side of the first valve body 104. The sensor 101 can be configured to detect the oil and gas pressure and, in the event of an emergency of oil and gas, the servo motor 106 can be controlled to start the switch valve cover 126 to release the oil and gas and close the oil and gas transportation.

One end of the valve sleeve 127 is connected to the second piston ring 129 and penetrates the fixing bolt 128. The second piston ring 129 and the third piston ring 130 are usually made of corrosion-resistant and wear-resistant materials such as PP (polypropylene) or HDPE (high-density polyethylene), which can prevent oil and gas from leaking from the side of the valve sleeve 127. The fixing bolt 128 is connected by penetrating the third piston ring 130 and is connected to the two sides of the second valve body 109. The third piston ring 130 can prevent oil and gas from leaking from the two sides of the second valve body 109.

[0033] In this embodiment, the fixing bolt 128 is used to prevent the valve sleeve 127 from loosening or falling off due to the pressure generated when discharging oil and gas. The second piston ring 129 and the third piston ring 130 can prevent oil and gas from leaking from both sides of the valve sleeve 127 and the second valve body 109.

The first manual valve 107 and the second manual valve 108 are connected through a connecting arc ring 116. The connecting arc ring 116 is usually made of corrosion-resistant and wear-resistant materials such as PP (polypropylene) or HDPE (high-density polyethylene), which can prevent oil and gas from entering the first manual valve 107 and the second manual valve 108 and leaking. One end of the connecting arc ring 116 is connected to the second valve body. On 109, one end of the first manual valve 107 and the second manual valve 108 are connected and fixed to the first fixed plate 120 by welding, the first fixed plate 120 is connected and fixed to the second fixed plate 121 by bolts, the second fixed plate 121 is installed with an oil and gas pipe 122, the first manual valve 107 and the second manual valve 108 are internally installed with a blocking ball 133, the blocking ball 133 has a through hole 134 therein, the blocking ball 133 can block the flow of oil and gas, the blocking ball 133 has a through hole 134 therein for discharging oil and gas, the blocking ball 133 is connected and fixed to the connecting column 132 by bolts, the connecting column 132 is connected and fixed to the rotating rod 118 by welding, the rotating rod 118 and the connecting column 132 pass through the inside of the guide sleeve column 119, and the upper end of the rotating rod 118 is connected and fixed to the rotating handle 117 by bolts.

[0038] When in use, first, the sensor 101 can be set to detect the oil and gas pressure and in the event of an oil and gas emergency, the servo motor 106 can be controlled to start the switch valve cover 126 to release the oil and gas and close the oil and gas transportation. When the servo motor 106 is started, the threaded screw 110 is driven to rotate, and the movable valve block 111 is driven to move up and down, and then the connecting bolt 125 and the valve cover 126 are moved up and down. The up and down movement of the valve cover 126 can release or close the oil and gas flowing out of the valve sleeve 127. The oil and gas flow to the inside of the oil and gas steel pipe 131 through the oil and gas transportation pipeline, and then flow out of the valve sleeve 127 from the inside of the oil and gas steel pipe 131. After that, the oil and gas can be transported and discharged from the first manual valve 107 and the second manual valve 108 on both sides of the second valve body 109.
