[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and adjust and control the parameters of the transported medium. According to its functions, it can be divided into shut-off valves, check valves, regulating valves, etc. A valve is a control component in a fluid transportation system and has functions such as cutoff, regulation, diversion, prevention of backflow, pressure stabilization, flow splitting, or overflow pressure relief.

[0003] The patent with the publication number of CN220959924U discloses a diameter detection device for valve production. By setting an arc-shaped plate and a spring to support and fix the inner side of the valve, it can fix valves of various models for detection. When the staff reads the diameter data, a pointer alignment is used, and the pointer not only points accurately. Although this device can fix multiple valves at one time and detect multiple valves, reading the data and adjusting the clamping plate both require separate adjustment, and the manual adjustment and fixation of each valve have low efficiency, resulting in the overall efficiency needing to be further improved. Moreover, the manual reading is relatively slow, so further improvement is needed. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1-3 shown, it relates to a diameter detection device, including a detection table 1. A plurality of support feet 2 are fixed on the lower surface of the detection table 1. A strip-shaped groove 101 is opened in the middle of the detection table 1. A positioning component 3 for fixing a valve is installed on the lower surface of the detection table 1 and near the strip-shaped groove 101. A plurality of vertical rods 4 are fixed on the upper surface of the detection table 1. A lifting plate 6 is slidably connected to the surfaces of the plurality of vertical rods 4. The tops of the plurality of vertical rods 4 are fixedly connected together with a top plate 5. An electric telescopic rod 7 is fixed on the upper surface of the top plate 5. The telescopic end of the electric telescopic rod 7 is fixedly connected to the upper surface of the lifting plate 6. Symmetric first clamping plate 8 and second clamping plate 9 are arranged below the lifting plate 6. A laser rangefinder 10 is fixed at the top of the first clamping plate 8. Two pushing components 11 for driving the first clamping plate 8 and the second clamping plate 9 to move are installed on both sides of the lower surface of the lifting plate 6. A controller 12 is installed on the upper surface of the detection table 1.

[0021] The positioning component 3 includes two first cylinders 31 fixed on the lower surface of the detection table 1 and on both sides of the strip-shaped groove 101. The telescopic ends of the two first cylinders 31 are fixedly connected with inner support plates 32. The tops of the two inner support plates 32 pass through the strip-shaped groove 101 and extend to the upper surface of the detection table 1.

[0022] By simultaneously shortening the two first cylinders 31, the two inner support plates 32 are driven to move away from each other, and the two inner support plates 32 can be used to position the valve from the inside of the valve.

[0023] Rubber pads 33 are fixedly connected to the sides of the two inner support plates 32 away from each other.

[0024] The rubber pads 33 can play a role in protecting the inner wall of the valve, and the rubber pads 33 can increase the friction between the inner support plates 32 and the inner wall of the valve, ensuring the stability of fixing the valve.

[0025] Both of the two pushing components 11 include vertical plates 111 fixed to the lower surface of the lifting plate 6. A second cylinder 112 is fixed to the bottom end of the vertical plate 111. A sleeve 113 is slidably sleeved on the surface of the telescopic end of the second cylinder 112. The two sleeves 113 are respectively fixedly connected to the first clamping plate 8 and the second clamping plate 9.

[0026] When the two second cylinders 112 extend simultaneously, they can drive the first clamping plate 8 and the second clamping plate 9 to approach each other, so that the first clamping plate 8 and the second clamping plate 9 are attached to the outer wall of the valve. At this time, the distance between the first clamping plate 8 and the second clamping plate 9 is the diameter of the valve.

[0027] A pressure sensor 115 is fixed to the inner side wall of the sleeve 113. A spring 114 is fixedly connected to the pressure measuring end of the pressure sensor 115 and the telescopic end of the second cylinder 112. Both the pressure sensor 115 and the second cylinder 112 are electrically connected to the controller 12.

[0028] When the two second cylinders 112 extend to drive the first clamping plate 8 and the second clamping plate 9 to be attached to the valve, the spring 114 will be compressed. The pressure sensor 115 can detect this pressure value. When the pressure value reaches the preset value of the controller 12, the controller 12 controls the second cylinder 112 to stop extending, so that valves with different diameters can be detected.

[0029] A strip-shaped opening 116 is formed in the side wall of the sleeve 113. A sliding rod 117 is fixed to the surface of the telescopic end of the second cylinder 112, and the sliding rod 117 is slidably connected to the strip-shaped opening 116. The cooperation between the sliding rod 117 and the strip-shaped opening 116 can prevent the sleeve 113 from separating from the telescopic end of the second cylinder 112.

[0030] Working principle: Place the valve to be detected on the surface of the detection table 1, and make the two inner support plates 32 located inside the valve. After starting the detection, the controller 12 controls the two first cylinders 31 to shorten simultaneously, driving the two inner support plates 32 to support and fix the valve from inside the valve. Then the electric telescopic rod 7 drives the lifting plate 6 to descend, so that the first clamping plate 8 and the second clamping plate 9 are located on both sides of the valve. Subsequently, the two second cylinders 112 extend simultaneously, so that the first clamping plate 8 and the second clamping plate 9 are attached to the outer side wall of the valve. Until the pressure sensor 115 detects that the extrusion force received by the spring 114 reaches the preset value, the second cylinder 112 stops extending. At this time, the distance between the first clamping plate 8 and the second clamping plate 9 measured by the laser rangefinder 10 is the diameter of the valve. After the detection is completed, the two second cylinders 112 first drive the first clamping plate 8 and the second clamping plate 9 to separate from the valve, then the electric telescopic rod 7 drives the lifting plate 6 to reset, and finally the first cylinder 31 extends to drive the inner support plate 32 to separate from the inner wall of the valve. Finally, take away the valve and replace it with a new valve for detection.

Obviously, according to the content of this specification, many modifications and variations can be made.
