[0002] Gas regulating valves are usually installed on gas branch pipes connected to gas-using equipment. Their main function is to regulate the flow and pressure of gas to ensure the normal operation of gas-using equipment. With the continuous development of related technologies, many types of gas regulating valves have been derived, including straight-through gas regulating valves, angle gas regulating valves, and check gas regulating valves. Compared with general gas regulating valves, high-sealing gas regulating valves have enhanced sealing properties. Therefore, high-sealing gas regulating valves have higher safety.

[0025] A square sleeve 5 is fixedly connected to the outer wall of the protective sleeve 2 on the side of the square column 3, and the square sleeve 5 and the square column 3 are slidably connected, and the protective sleeve 2 and the support frame 4 are closely arranged, so that when the user moves the protective sleeve 2 to disassemble and assemble the protective sleeve 2, the protective sleeve 2 drives the square sleeve 5 to slide relative to the square column 3.

[0026] The limiting mechanism 7 includes a sleeve 701, a transmission rod 702 and a clamping rod 703, and the sleeve 701 is movably installed on the outer wall of the support column 6, and the upper surface of the sleeve 701 is fixedly connected to the transmission rod 702, and the upper end of the transmission rod 702 is fixedly provided with a clamping rod 703, so that the protective cover 2 can be stably installed on the outside of the electric valve body 1 through the limiting mechanism 7, so that the electronic components on the electric valve body 1 are protected by the protective cover 2.

[0027] The sleeve 701 and the support column 6 are slidably arranged, and the end surface of the sleeve 701 is connected to the inner wall of the support frame 4 through the spring 8, so that the sleeve 701 can be elastically supported by the spring 8 and the sleeve 701 can slide relative to the support column 6.

[0028] The transmission rod 702 and the support frame 4 form a sliding structure, so that when the user moves the clamping rod 703 , the clamping rod 703 drives the transmission rod 702 to slide relative to the support frame 4 .

[0029] The clamping rod 703 and the protective cover 2 are slidably arranged, and the cross-section of the clamping rod 703 is arranged in an "L" shape, so that the spring 8 pushes the sleeve 701, so that the transmission rod 702 drives the clamping rod 703 to be stably inserted into the protective cover 2, thereby limiting the protective cover 2.

[0030] The positioning frame 11 and the knob 12 are threadedly connected, so that the user can rotate the knob 12 to move the knob 12 relative to the positioning frame 11 .

[0031] The knob 12 and the pressure plate 13 are rotatable, so that the user can continuously rotate the knob 12, so that the knob 12 drives the pressure plate 13 to move, and the pressure plate 13 drives the anti-slip rubber pad 14 to fit tightly against the gas pipeline connected to the electric valve body 1, thereby improving the stability of the connection between the pipeline and the electric valve body 1, and avoiding the phenomenon of gas leakage caused by loosening of the gas pipeline during operation.

[0032] Working principle: When using this highly sealed gas regulating valve, first Figure 1-5As shown, both ends of the inner wall of the electric valve body 1 are provided with internal threads. Therefore, when using the electric valve body 1, the user inserts the gas pipe into the electric valve body 1 and tightens the gas pipe. As the gas pipe continues to rotate, the end face of the gas pipe finally clings to the sealing ring 10 on the sealing ring 9, thereby completing the connection between the gas pipe and the regulating valve. Then the user rotates the knob 12, and then the knob 12 moves relative to the positioning frame 11. Next, the knob 12 drives the pressure plate 13 to move toward the gas pipe. As the user continues to rotate the knob 12, the pressure plate 13 finally drives the anti-skid rubber pad 14 to cling to the gas pipe. Similarly, the remaining knobs 12 are operated to complete the limiting of the gas pipe to prevent the gas pipe from loosening during use, thereby making the gas pipe always cling to the sealing ring 10, so the sealing of the valve body is improved. Then the user pulls the clamping rod 703, and then The locking rod 703 drives the transmission rod 702 to move, and then the transmission rod 702 drives the sleeve 701 to slide along the support column 6. At this time, the sleeve 701 compresses the spring 8 and deforms. Then the user sets the protective cover 2 to the outside of the electric valve body 1, and as the protective cover 2 moves, the protective cover 2 drives the square cover 5 to be set to the outside of the square column 3. At the same time, the protective cover 2 fits the support frame 4. Then the user releases the locking rod 703. At this time, the spring 8 resets and pushes the sleeve 701 so that the sleeve 701 drives the transmission rod 702 to move, so that the transmission rod 702 drives the locking rod 703 to insert the protective cover 2, and then completes the fixation of the protective cover 2, so that the protective cover 2 is stably installed on the outside of the electric valve body 1 to provide protection for the electronic components on the electric valve body 1. Therefore, the device enhances the protection, thereby preventing the electronic components on the regulating valve from being damaged due to external force collision.
