Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, in particular to a gas pressure sensor detection device. Background Art

[0002] Common gas pressure sensors include resistive strain gauge, capacitive strain gauge, piezoelectric strain gauge, resonant strain gauge, etc. The working principle of the resistive strain gauge is as follows: the strain gauge is pasted on an elastic film or metal diaphragm. When the gas pressure changes, the sensitive element undergoes a slight deformation, causing the resistance value on the strain gauge to change. The gas pressure information can be obtained by detecting the resistance change.

[0003] The gas pressure sensor is used to measure the pressure of the gas pipeline and convert the measurement result into a corresponding electrical signal. The gas equipment needs to maintain a certain gas pressure to operate normally. Before the pressure sensor is installed and used, it is necessary to use a detection device to detect its accuracy. In the existing technology, most detection devices are unable to detect the pressure of the gas when it is circulating and closed. Most of them can only detect the pressure of the gas when it is closed, resulting in a single detection method for the pressure detector, which is unable to perform accurate detection and is insufficient in practicality. Therefore, it is necessary to redesign the gas pressure sensor detection device to address the above problems. Utility Model Content

The connecting mechanism includes a connecting sleeve 7 fixedly installed on the outer wall of the rotating shaft 5, and each connecting rod 8 is fixedly installed on the outer wall of the connecting sleeve 7.

[0023] The ends of two connecting rods 8 are commonly fixedly connected with a first detection pipe 9, and the end of the first detection pipe 9 is an open design. The ends of the other two connecting rods 8 are commonly fixedly connected with a second detection pipe 10, and the end of the second detection pipe 10 is a closed design. The ends of the first detection pipe 9 and the second detection pipe 10 are both fixedly installed with connecting flanges 11, and the outer walls of the first detection pipe 9 and the second detection pipe 10 are both fixedly installed with connecting heads 12 connected to the interior.

The supporting mechanism includes a supporting plate 13 fixedly installed on the upper end surface of the base plate 1, and the moving frame 14 is fixedly installed on the outer wall of the support plate 13.

[0024] A double-headed screw 15 is rotatably installed inside the moving frame 14, and a second motor 16 connected to the double-headed screw 15 is fixedly installed on the outer wall of the moving frame 14. Two moving sleeves 18 are threadedly installed on the outer wall of the double-headed screw 15 through a limiting mechanism. The limiting mechanism includes a limiting rod 17 fixedly installed inside the moving frame 14, and the limiting rod 17 slides through the two moving sleeves 18. The limiting rod 17 can limit the two moving sleeves 18 so that the two moving sleeves 18 can only move axially along the outer wall of the double-headed screw 15. The outer walls of the two moving sleeves 18 are fixedly installed with clamping plates 20 through a connecting mechanism. The connecting mechanism includes a connecting rod 19 fixedly installed on the outer walls of the two moving sleeves 18, and the end of the connecting rod 19 is fixedly connected to the outer wall of the clamping plate 20. The inner walls of the two clamping plates 20 are fixedly installed with anti-skid pads 21, and the anti-skid pads 21 are made of rubber.

[0025] When the utility model is used, the bottom plate 1 can drive the first detection pipeline 9 and the second detection pipeline 10 to move through the multiple pulleys 3, the first motor 6 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the multiple connecting rods 8 to rotate through the cooperation of the connecting sleeve 7.

The two movable sleeves 18 then drive the two clamping plates 20 to approach each other through the cooperation of the connecting rod 19, and clamp the outer wall of the sensor body 2 with the rubber anti-skid pad 21, thereby preventing the connection between the sensor body 2 and the connecting head 12 from loosening when the gas is flowing, avoiding gas leakage that affects the accuracy of the detection, and the rubber anti-skid pad 21 can increase the friction with the outer wall of the sensor body 2, thereby improving the clamping and fixing effect.
