Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5 An embodiment of this utility model is provided: a gas valve flow calibration and detection device, including a detection platform 1 and a detector body 2. The detector body 2 is provided at one end of the top of the detection platform 1, and a slot 24 is provided in the middle of the top of the detection platform 1. A lead screw 3 is provided in the middle of the detection platform 1, and a threaded block 4 is connected to the lead screw 3 by a thread. A moving block 5 is provided on the top of the threaded block 4 through the slot 24. A motor 6 is provided at one end of the detection platform 1 corresponding to the position of the lead screw 3, and the output end of the motor 6 extends into the detection platform 1 through a bearing and a coupling and is connected to the lead screw 3.
[0024] Specifically, such as Figure 1 and Figure 5 As shown, the motor 6 drives the lead screw 3 to rotate, and the lead screw 3 drives the threaded block 4 to move. The threaded block 4 can drive the moving block 5 to move through the slot 24. The moving block 5 can drive the clamped and fixed gas valve to move towards the detector body 2, and can connect to the detector body 2. Then, an external gas source can be connected, and the detector body 2 can detect its flow rate.
[0025] A frame 18 is provided at the center of the bottom of the movable block 5, and a slot is provided in the threaded block 4 corresponding to the frame 18. The frame 18 is inserted into the threaded block 4 through the slot. A groove 19 is provided at the center of the bottom of the frame 18, and sliders 23 are slidably connected to both ends of the groove 19. A spring 21 is provided between the sliders 23, and a limiting block 20 is provided at the top of each slider 23. A limiting groove is provided in both the frame 18 and the threaded block 4 corresponding to the limiting block 20. A threaded rod 17 is provided at the center of the top of the frame 18, and the threaded rod 17 is connected to the threaded block 4 through the groove. A T-shaped block 22 is connected by a thread, and the two sides of the T-shaped block 22 are in contact with the inclined surface of one end of the limiting block 20. The bottom end of the moving block 5 corresponding to the threaded rod 17 is provided with a groove 14, and the top end of the threaded rod 17 extends into the groove 14 through a bearing to form a smooth shaft section. A gear 2 16 is provided on the smooth shaft section of the threaded rod 17 in the groove 14. A turntable 7 is provided on the outside of the moving block 5 on one side of the top of the gear 2 16, and a rotating rod on the inside of the turntable 7 extends into the groove 14 through a bearing to provide a gear 15. The gear 15 and the gear 2 16 mesh with each other.
[0026] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, the insert frame 18 at the bottom of the movable block 5 is inserted into the slot of the threaded block 4. Then, the turntable 7 can be rotated to drive the gear 15 on the rotating rod to rotate, which in turn drives the gear 16 meshing with it to rotate, which in turn drives the threaded rod 17 to rotate, which in turn drives the inverted T-shaped block 22 to move downward. The two sides of the inverted T-shaped block 22 can slide along the inclined surface of one end of the limiting block 20, thereby pushing the limiting block 20 to move to both sides. At this time, the slider 23 slides in the slide groove 19, and the spring 21 is stretched, which allows the limiting block 20 to move and be inserted into the limiting groove, so that the insert frame 18 can be connected to the threaded block 4. When it is necessary to disassemble the movable block 5, the turntable 7 can be rotated in the opposite direction, so that the limiting block 20 can be retracted under the action of the spring 21. The movable block 5 can be easily assembled and disassembled, and different movable blocks 5 can be replaced to meet the detection requirements of single or multiple gas valves.
[0027] The top two sides of the movable block 5 are provided with support plates 10, and the middle position of the inner side of the support plate 10 is provided with a connecting block 13. The inner side of the connecting block 13 is provided with a clamping block 9, and the inner side of the clamping block 9 is provided with an arc-shaped pad. The middle position of the outer side of the support plate 10 is provided with a telescopic rod 8, and the output end of the telescopic rod 8 extends to the inner side of the support plate 10 and connects with the connecting block 13.
[0028] Specifically, such as Figure 1 and Figure 2 As shown, the telescopic rod 8 drives the connecting block 13 to move, which in turn drives the clamping block 9 to move. This allows the clamping block 9 to clamp and fix the gas valve, preventing the gas valve from shifting during testing.
[0029] Metal locking blocks 11 are provided in the middle of the outer side of the clamping block 9, and the corresponding connecting blocks 13 are provided with slots. The locking blocks 11 are engaged with the connecting blocks 13 through the slots. A magnetic block is provided in the middle of the slot of the connecting block 13, and the connecting block 13 is magnetically attracted to the locking blocks 11 through the magnetic block. Threaded holes are provided in the middle of the corresponding positions of the locking blocks 11 and the connecting blocks 13, and fixing screws 12 are threadedly connected to the threaded holes of the locking blocks 11 and the connecting blocks 13. Nuts are screwed onto both ends of the fixing screws 12 through the threads.
[0030] Specifically, such as Figure 2 As shown, the clamping block 9's locking block 11 is engaged in the slot of the connecting block 13, and the magnetic block attracts the locking block 11, initially fixing the position of the clamping block 9. Then, the fixing screw 12 is passed through the corresponding threaded holes of the locking block 11 and the connecting block 13, and the fixing screw 12 is firmly installed in them through the threaded connection. The appropriate clamping block 9 can be flexibly replaced according to the gas valve of different specifications and sizes, improving the versatility and applicability of the device, and meeting the detection needs of more different types of gas valves.
[0031] Working principle: In use, insert the bottom frame 18 of the movable block 5 into the slot of the threaded block 4. Then, rotate the turntable 7 to drive the gear 15 on the rotating rod to rotate, which in turn drives the gear 16 meshing with it to rotate. The gear 16 drives the threaded rod 17 to rotate, which in turn drives the inverted T-shaped block 22 to move downward. The two sides of the inverted T-shaped block 22 can slide along the inclined surface of one end of the limiting block 20, thereby pushing the limiting block 20 to move to both sides. At this time, the slider 23 slides in the slide groove 19, and the spring 21 is stretched, which allows the limiting block 20 to move and lock into the limiting groove, allowing the insert frame 18 to connect with the threaded block 4. When it is necessary to disassemble the movable block 5, the turntable 7 can be rotated in the opposite direction, so that the limiting block 20 can be retracted under the action of the spring 21. The movable block 5 can be easily assembled and disassembled, and different movable blocks 5 can be replaced to meet the detection requirements of single or multiple gas valves. Then, the clamping block 11 of the clamping block 9 is locked onto the connecting block 1. The clamping block 9 is initially fixed in position by magnetically attracting the clamping block 11 into the slot of the 3rd block. Then, the fixing screw 12 is passed through the threaded holes corresponding to the clamping block 11 and the connecting block 13. The fixing screw 12 is securely installed in the slot through threaded connection. The appropriate clamping block 9 can be flexibly replaced according to the gas valve of different specifications and sizes, improving the versatility and applicability of the device. After assembly, the telescopic rod 8 can drive the connecting block 13 to move, and the connecting block 13 can drive the clamping block 9 to move, so that the clamping block 9 can clamp and fix the gas valve, preventing the gas valve from shifting during detection. Then, the motor 6 can be started to drive the lead screw 3 to rotate, so that the lead screw 3 can drive the threaded block 4 to move, and the threaded block 4 can drive the moving block 5 to move through the slot 24. The moving block 5 can drive the clamped and fixed gas valve to move towards the detector body 2, so that it can be connected to the detector body 2. Then, an external gas source can be connected, so that the detector body 2 can detect its flow rate.
