At the same time, the first limit plug rod 62 is used to lock the connecting shaft 10 inside the valve control chamber 5 when it is not in operation, so as to avoid the connection shaft 10 from rotating and loosening due to vibration of the equipment pipeline, thereby affecting the valve sealing effect.

[0049] See also Figure 1-Figure 4 , Figure 7-Figure 8 Two diversion chambers 13 are provided inside the valve support seat 2, and flame-retardant inner pads 14 are installed on the inner walls of the two diversion chambers 13. Sealing flanges 3 are installed at the connection between the valve support seat 2 and the first sleeve 71. A buffer spring 12 is sleeved on the outer side of the connecting shaft 10, and an elastic pad is installed between the two diversion chambers 13.

[0050] The present invention reinforces the sealing treatment when the valve support seat 2 and the first sleeve 71 are connected by the sealing flange 3, and the internal gas is normally transported through the two diversion chambers 13. By installing a flame-retardant inner pad 14 on the inner wall of the diversion chamber 13, the high temperature resistance effect during use is improved, the service life of the equipment is extended, and the safety hazards are reduced. The elastic pad is used to buffer the pressure plate 17 during the isolation treatment, thereby extending the service life of the equipment.

[0051] See also Figure 1-Figure 4 , Figure 7-Figure 8The two mounting chucks 73 are each provided with a mounting hole 77 for use with the first positioning bolt 76 , the two second sealing rings 74 are each provided with a first sealing inner gasket 78 , the first sealing inner gasket 78 is provided with an O-ring 75 , and the two mounting chucks 73 are each provided with a second sealing inner gasket 79 .

An adjustment shaft 82 is rotatably connected between the two supporting bottom plates 81, and the adjustment shaft 82 is fixedly connected to the bottom of the two supporting upright plates 8 through a second limit sleeve. The second limit sleeve is located between the two supporting upright plates 8 and on the outside of the adjustment shaft 82. The outside of one of the supporting upright plates 8 is threadedly connected with four second positioning bolts 83 extending to the inside of the other supporting upright plate 8.

[0054] The present invention uses a second positioning bolt 83 to limit the installation of the two support vertical plates 8, and uses a third positioning bolt 88 to limit the installation of the connecting plate 87 and the support vertical plate 8, and cooperates with the support top plate 84 to slide normally inside the support vertical plate 8. When the adjustment is completed, the corresponding support top plate 84 is fixed by the limiting pin 85 to achieve the limiting processing effect. The limiting pin 85 can be a limiting screw or a limiting screw, which is used to adjust the height of the overall equipment during installation and facilitate subsequent maintenance. By turning the adjustment shaft 82, the second limiting sleeve is driven to rotate, thereby fine-tuning the angle of the support vertical plate 8. At the same time, the support of the support vertical plate 8 during fine-tuning is suitable for different installation scenarios, which improves flexibility during use.

[0055] See also Figure 1-Figure 10A pressure relief valve 18 is installed on one side of the valve control compartment 5 and below the adsorption plate 6.

[0056] The present invention reinforces the installation of the valve mounting seat 1 and the mounting cross plate 15 through the fourth positioning bolt 20, which is convenient for subsequent normal disassembly and assembly, and sets the automatic pressure relief time of the pressure relief valve 18 to perform timed and fixed-point pressure relief processing. The control chip is used to control the operation of the pressure relief valve 18, thereby realizing normal management of the equipment. There is no need for a large number of electronic equipment to assist in the installation, which saves the overall use and installation cost and facilitates effective cost control.

[0057] Working principle:

[0058] When in use, the sealing flange 3 is used to reinforce the sealing treatment when connecting the valve support seat 2 and the first sleeve 71, and the internal gas is normally transported through the two diversion chambers 13. By installing a flame-retardant inner pad 14 on the inner wall of the diversion chamber 13, the high temperature resistance effect during use is improved, the service life of the equipment is extended, and the safety hazards are reduced. The elastic pad is used to buffer the pressure plate 17 during the isolation treatment, thereby extending the service life of the equipment.

[0059] The present invention improves the sealing performance during use by arranging O-rings 75, second sealing inner gaskets 79, and first sealing inner gaskets 78. The first positioning bolts 76 are used to reinforce the connection with the connecting plate 7 through the mounting holes 77, and at the same time facilitate subsequent quick disassembly and assembly for maintenance. The three first positioning bolts 76 are used to reinforce the mounting chuck 73, the second sleeve 72, and the connecting plate 7 respectively. By manually turning the handwheel 4, the connecting shaft 10 is driven to rotate, the second screw 11 is driven to rotate, and the pressure plate 17 is driven to move gradually downward until it enters the valve control chamber 5 for isolation. A mounting cross plate 15 is installed inside the valve mounting seat 1 to enhance the isolation effect.

[0060] By manually turning the first screw 65, the first sealing ring 67 is driven to move to one side, the fixed plate 61 is driven to move to one side, and the first limit rod 62 is driven to enter the valve control chamber 5 to limit the connecting shaft 10. At this time, the first screw 65 that has been adjusted is limited by turning the limit nut 66. The overall limit structure is simple and easy to operate, and it is convenient for regular disassembly and maintenance. At the same time, the first limit rod 62 is used to lock the connecting shaft 10 inside the valve control chamber 5 when it is not in operation, so as to avoid the connecting shaft 10 from rotating loose due to vibration of the equipment pipeline, thereby affecting the sealing effect of the valve. The control valve is opened, and lubricating oil is added to the adsorption pad 68 through the refueling pipe 69 to ensure the normal operation of the limit locking mechanism and extend the service life of the equipment.

[0061] The two support uprights 8 are installed in a limited position by the second positioning bolt 83, and the connecting piece 87 and the support upright 8 are installed in a limited position by the third positioning bolt 88, and the support top plate 84 slides normally inside the support upright 8 in cooperation with the support top plate 8. When the adjustment is completed, the corresponding support top plate 84 is fixed by the limiting latch 85 to achieve the limiting processing effect, and the height of the overall equipment is adjusted during installation, and it is convenient for subsequent maintenance. By turning the adjustment shaft 82, the second limiting sleeve is driven to rotate, so as to fine-tune the angle of the support upright 8. At the same time, the support during fine-tuning of the support upright 8 is suitable for different installation scenarios, which improves the flexibility during use. The valve mounting seat 1 and the mounting cross plate 15 are reinforced and installed by the fourth positioning bolt 20, which is convenient for subsequent normal disassembly and assembly, and the automatic pressure relief time of the pressure relief valve 18 is set to perform timed and fixed-point pressure relief processing.

[0062] The control chip controls the operation of the pressure relief valve 18, realizing normal management of the equipment. It does not require a large amount of electronic equipment for auxiliary installation, saves the overall use and installation cost, facilitates effective cost control, and realizes the normal use and control of the valve while facilitating the support and adjustment of the valve installation and ensuring the sealing connection of the valve.
