Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection.

Example 1, as shown in Figures 1-4, a gas pipeline is easy to disassemble the valve, when disassembling, first remove the first bolt 9, so that the pipe body 11 loses its position, at this time rotating the rotating rod 6, the rotating rod 6 will Drive the bevel gear set 7 to rotate, drive the screw rod 4 to rotate, the screw rod 4 will drive the moving block 8 to start moving, and the moving block 8 will drive the pipe body 11 to start moving away from the valve. Then turn the rotating rod 6 in the reverse direction, so that the screw rod 4 starts to rotate in the reverse direction, and then the moving block 8 will drive the pipe body 11 to open toward the valve, and the first sealing ring 12 is in contact with the side of the valve body 1. Therefore, the pipe body 11 and the valve can be quickly installed, which saves a lot of time and improves the work efficiency. The setting of the limit block 23 and the limit rod 10 can limit the movement of the pipe body 11. .

Embodiment 1, as shown in Figures 1 and 4, is set by the threaded rod 17 and the threaded barrel 16, and the pressing plate 20 is driven to move downward by rotating the threaded rod 17, and the pressing plate 20 will drive the valve core 21 to move downward. The setting of the seat 22 can realize the control of the gas flow, and then through the setting of the second bolt 24, the threaded rod 17 and the valve core 21 can be quickly taken out, so as to facilitate the rapid maintenance of the inside of the valve body 1, through the second seal The arrangement of the ring 19 can improve the sealing performance of the valve body 1 .

Working principle: an easy-to-remove valve for gas pipelines, and an easy-to-remove valve for gas pipelines. When the valve needs to be disassembled, the first bolt 9 is first rotated, and the first bolt 9 is separated from the first threaded hole, so that the installation frame 2 and the moving block are connected. 8 The connection with the limit block 23 is lost, and then the turning handle starts to rotate. The turning handle drives the rotating rod 6 to rotate. The rotating rod 6 will start to run with the bevel gear set 7, and start to drive the screw rod 4 to rotate. The rotation of the screw rod 4 makes the movement The block 8 moves, and then through the setting of the limit block 23 and the limit rod 10, the moving block 8 can smoothly drive the pipe body 11 to move in the direction away from the valve, and separate the pipe body 11 from the valve body 1, so as to achieve In order to quickly disassemble the valve body 1, after the maintenance is completed, align the pipe body 11 with the installation groove 3, and then reverse the rotation rod 6, so that the screw rod 4 starts to rotate in the reverse direction, and the moving block 8 will drive the The pipe body 11 enters the installation groove 3, and the pipe body 11 is docked with the valve body 1. The installation of the first sealing ring 12 improves the sealing performance of the installation, and then the pipe body 11 is fixed by the first bolt 9, so as to achieve In order to quickly install the pipe body 11 and the valve, a lot of time is saved and work efficiency is improved.

By rotating the threaded rod 17, the threaded rod 17 will drive the pressure plate 20 to move downward, and the pressure plate 20 will drive the valve core 21 to move downward. Through the setting of the pressure seat 22, rapid control of the gas can be achieved, and at the same time, the valve body needs to be repaired. 1 internal structure, through the arrangement of the second bolt 24, the mounting plate 13 can be quickly disassembled, the threaded rod 17 and the valve core 21 can be taken out, so as to facilitate the rapid maintenance of the inside of the valve body 1, through the second sealing ring The arrangement of 19 and the sealing block 18 can improve the sealing performance of the valve body 1 .
