Technical Field

[0001] The utility model relates to the technical field of pressure regulators, in particular to a valve port fixing device for a pressure regulator. Background Art

[0002] The regulator valve is a component in the pressure regulator that controls the pressure of gas or liquid. When the pressure is too high, the regulator valve will open to release some gas or liquid to relieve the pressure. When the pressure is too low, the regulator valve will close to prevent excessive outflow of gas or liquid, thereby maintaining a stable pressure in the system.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As described, the technical solution in the embodiment of the present application is to effectively solve the problem that in the existing valve port body 5 fixation, multiple nuts, flanges and other workpieces are used to fix the multiple valve port bodies 5. When the valve port body 5 needs to be repaired, the disassembly of the fixing parts is cumbersome, resulting in low maintenance efficiency of the valve port body 5. The overall idea is as follows: A pressure regulator valve port fixing device includes a support frame 1 and a valve port body 5. The support frame 1 is provided with a clamping mechanism for fixing the valve port body 5. The clamping mechanism includes a first fixing ring 2 and a second fixing ring 3. The first fixing ring 2 and the second fixing ring 3 are both located on the inner side wall of the support frame 1. The first fixing ring 2 and the second fixing ring 3 will approach each other. After the first fixing ring 2 and the second fixing ring 3 approach each other to clamp and tighten the valve port body 5, the user can stop rotating the threaded rod 21 to complete the fixation of the valve port body 5;

[0024] The valve body 5 is located between the first fixing ring 2 and the second fixing ring 3. Four supporting rods 11 are fixedly installed at the lower end of the support frame 1. Rectangular grooves 12 are penetrated at both side ends of the support frame 1. The inner side walls of the two rectangular grooves 12 are fixedly installed with mounting plates 13. The side ends of the two mounting plates 13 are fixedly installed with round shafts 14. The side ends of the two round shafts 14 are rotatably installed with gears 15. The side ends of the support frame 1 are also penetrated with threaded grooves 16. The side ends of the first fixing ring 2 are rotatably installed with threaded rods 21. The threaded rods 21 are threadedly rotatably installed on the inner side walls of the threaded grooves 16. When the user needs to clamp and fix the valve body 5, the valve body 5 and the pressure regulator can be connected, and the valve body 5 can be placed between the first fixing ring 2 and the second fixing ring 3. The user can rotate the threaded rod 21, and the rotation of the threaded rod 21 drives the first fixing ring 2 to slide in the support frame 1.

[0025] The first side rods 22 are fixedly installed on the two side ends of the first fixing ring 2, and the first racks 23 are fixedly installed on the lower ends of the two first side rods 22, and the two first racks 23 are respectively meshed with the gear 15. A telescopic rod 31 is fixedly installed between the second fixing ring 3 and the inner side wall of the support frame 1, and the second side rods 32 are fixedly installed on the two side ends of the second fixing ring 3, and the two second side rods 32 are respectively meshed with the gear 15. The first rack 23 and the second rack 33 are both slidably located on the inner side wall of the rectangular groove 12. The movement of the first fixing ring 2 will drive the two first side rods 22 to slide, and the movement of the two first side rods 22 will drive the first rack 23 to move. The movement of the first rack 23 will drive the gear 15 to rotate. The rotation of the gear 15 will drive the second rack 33 to move. The movement of the second rack 33 will drive the second side rod 32 to move, and the movement of the second side rod 32 will drive the second fixing ring 3 to move.

[0026] In view of the problems existing in the prior art, the utility model provides a pressure regulator valve port fixing device. The device cooperates with a first rack 23, a gear 15 and a second rack 33. When the multi-valve port body 5 needs to be repaired, by rotating the threaded rod 21, the first rack 23, the gear 15 and the second rack 33 can be used to simultaneously drive the second fixing ring 3 to move, thereby achieving the fixation and disassembly of the valve port body 5, thereby improving the maintenance efficiency.

[0027] Working principle:

[0028] When the user needs to clamp and fix the valve body 5, the valve body 5 and the pressure regulator can be connected, and the valve body 5 can be placed between the first fixing ring 2 and the second fixing ring 3. The user can rotate the threaded rod 21. The rotation of the threaded rod 21 drives the first fixing ring 2 to slide in the support frame 1. The movement of the first fixing ring 2 will drive the two first side rods 22 to slide. The movement of the two first side rods 22 will drive the first rack 23 to move. The movement of the first rack 23 will drive the gear 15 to rotate. The rotation of the gear 15 will drive the second rack 33 to move. The movement of the second rack 33 will drive the second side rod 32 to move. The movement of the second side rod 32 will drive the second fixing ring 3 to move, and then drive the telescopic rod 31 to lengthen. At this time, the first fixing ring 2 and the second fixing ring 3 will approach each other. After the first fixing ring 2 and the second fixing ring 3 are close to each other to clamp and tighten the valve body 5, the user can stop rotating the threaded rod 21. , complete the fixation of the valve port body 5. In the existing valve port body 5 fixation, it will use multiple nuts, flanges and other workpieces to fix the multiple valve port bodies 5. When the valve port body 5 needs to be repaired, the disassembly of the fixing parts is relatively cumbersome, resulting in low maintenance efficiency of the valve port body 5. The device is provided with a first rack 23, a gear 15 and a second rack 33 to cooperate. When the multiple valve port bodies 5 need to be repaired, by rotating the threaded rod 21, with the cooperation of the first rack 23, the gear 15 and the second rack 33, the second fixing ring 3 can be driven to move at the same time, thereby realizing the fixation and disassembly of the valve port body 5, thereby improving the maintenance efficiency. In addition, the device can realize the disassembly and fixation of the valve port body 5 by rotating the threaded rod 21, without the use of additional nuts, flanges and other tools, thereby avoiding the problem of parts loss and the need to replace parts during maintenance, thereby avoiding additional losses.
