[0003] The existing intelligent valve positioner includes a housing and a display screen. The housing contains a converter, gas delivery pipes at both ends of the left side, and pressure gauges on the outer sides of the gas delivery pipes. The top of the housing mates with the bottom of a cover, and mounting brackets are located at the four corners of the bottom of the cover. The display screen is mounted on the top of the cover. Gas is delivered to the housing through the gas delivery pipes, and the pressure gauges detect the gas pressure. Locking components are located on both sides of the housing, and a dehumidification unit is also included inside. The housing also includes a controller located on the front side. The input terminals of the converter and display screen are electrically connected to the output terminal of the controller, which in turn is electrically connected to the output terminal of an external power supply. This intelligent valve positioner is easy to disassemble and maintain, and has a long service life.

[0004] However, in the production environment, the equipment will vibrate during operation, and the air source pressure may also fluctuate, which makes the air tube easy to loosen or even come out from the external interface. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent valve positioner, which aims to solve the problem that in the production environment, the equipment will vibrate during operation, and the air source pressure may also fluctuate, which makes the air pipe easy to loosen or even fall out from the external interface.

[0006] To achieve the above objectives, this utility model provides an intelligent valve positioner, comprising a positioner body, an external pipe, and an air pipe. The external pipe is disposed on the positioner body, and the air pipe is disposed on the external pipe.

[0007] It also includes anti-detachment components.

[0008] The anti-detachment component includes a fixed frame, a movable block, a tension spring, a connecting block, an abutment frame, a limiting member, and a locking member. The fixed frame is fixedly connected to the external pipe and located on one side of the external pipe. The movable block is connected to the fixed frame through the limiting member and located on one side of the fixed frame. The two ends of the tension spring are fixedly connected to the fixed frame and the movable block, respectively. The tension spring is located on the side of the fixed frame closer to the movable block. The movable frame is slidably connected to the movable block and located on one side of the movable block. The connecting block is fixedly connected to the movable frame and located on one side of the movable frame. The abutment frame is fixedly connected to the connecting block and located on the side of the connecting block closer to the air tube. The limiting member is disposed on the fixed frame and connected to the movable block. The locking member is disposed on the movable block and abuts against the connecting block.

[0009] The limiting component includes a limiting cylinder and a sliding rod. The limiting cylinder is fixedly connected to the fixed frame and is located on one side of the fixed frame. The sliding rod is slidably connected to the limiting cylinder and fixedly connected to the moving block, and is located on the side of the limiting cylinder closer to the moving block.

[0010] The locking component includes a screw and a rotating head. The screw is threadedly connected to the moving block and abuts against the connecting block. The rotating head is fixedly connected to the screw and is located on one side of the screw.

[0011] The anti-detachment component also includes a rubber pad, which is fixedly connected to the abutment frame and located on one side of the abutment frame.

[0012] The anti-detachment component also includes a sealing gasket, which is disposed on the external pipe and located on the side of the external pipe closer to the air tube.

[0013] The anti-detachment component further includes an anti-detachment block, which is fixedly connected to the movable frame and located on the side of the movable frame closer to the movable block.

[0014] The anti-detachment component further includes a fixing member, which includes a first fixing seat and a second fixing seat.

[0017] This utility model discloses an intelligent valve positioner. When the air pipe is connected to the external pipeline, the operator pulls the moving block outward to stretch the tension spring. At the same time, the locking member abuts and pushes the abutment frame to clamp and fix the air pipe. After the abutment frame abuts the outside of the air pipe, the operator releases the moving block, causing the tension spring on the moving block to deform and rebound. Thus, the abutment frame clamps and fixes the air pipe, and the rebound of the tension spring pulls, enabling the air pipe to be more stably connected to the external pipeline. This prevents the air pipe connected to the positioner body from loosening or detaching from the external pipeline due to vibrations during equipment operation. Attached Figure Description

[0025] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] The first embodiment of this application is:

[0027] Please see Figures 1 to 3 ,in Figure 1 This is a structural schematic diagram of the intelligent valve positioner according to the first embodiment of this utility model. Figure 2 This is a schematic diagram of the anti-detachment component of the first embodiment of this utility model. Figure 3 This is a schematic diagram of the external pipe structure of the first embodiment of this utility model.

[0028] This utility model provides an intelligent valve positioner, including a positioner body 101, an external pipe 102, an air pipe 103, and an anti-detachment component. The anti-detachment component includes a fixing frame 104, a moving block 105, a tension spring 106, a moving frame 107, a connecting block 108, an abutment frame 109, a limiting component, a locking component, a rubber pad 110, a sealing washer 111, and an anti-detachment block 112. The limiting component includes a limiting cylinder 113 and a sliding rod 114, and the locking component includes a screw 115 and a rotating head 116. This solution addresses the issue that in production environments, equipment operation generates vibrations, and air source pressure may fluctuate, making it easy for the air pipe to loosen or even detach from the external interface. It is understood that this solution can be used in situations where it is necessary to clamp and fix the air pipe to the interface.

[0029] In this embodiment, there are two external pipes 102, which are disposed on the positioner body 101. There are also two air pipes 103, which can be connected to the two external pipes 102. The positioner body 101 can automatically detect the zero point, full stroke, and friction coefficient of the regulating valve and automatically set the control parameters. The structure of the positioner body 101, the external pipes 102, and the air pipes 103 is described in detail in the prior art CN216479241U, and will not be repeated here.

[0030] The fixed frame 104 is fixedly connected to the external pipe 102 and located on one side of the external pipe 102. The movable block 105 is connected to the fixed frame 104 through the limiting member and is located on one side of the fixed frame 104. The two ends of the tension spring 106 are fixedly connected to the fixed frame 104 and the movable block 105 respectively. The tension spring 106 is located on the side of the fixed frame 104 near the movable block 105. The movable frame 107 is slidably connected to the movable block 105 and is located on one side of the movable block 105. The connecting block 108 is fixedly connected to the movable frame 107 and is located on one side of the movable frame 107. The abutment frame 109 is connected to the connecting block 105. A connecting block 108 is fixedly connected and located on the side of the connecting block 108 near the air pipe 103. A limiting member is disposed on the fixed frame 104 and connected to the movable block 105. A locking member is disposed on the movable block 105 and abuts against the connecting block 108. There are four fixed frames 104, which are welded to the external pipe 102. There are four movable blocks 105, which are connected to the corresponding four fixed frames 104 via the limiting member. There are four tension springs 106, whose two ends are respectively fixed to the corresponding four fixed frames 104 and four movable blocks 105. The deformation capacity of the tension spring 106 can drive the moving block 105 to move. There are eight moving frames 107, which are slidably connected to four corresponding moving blocks 105. The moving blocks 105 can connect and support the movement of the moving frames 107. There are four abutting frames 109, which are welded to the eight moving frames 107. The movement of the moving frames 107 can connect and support the movement of the abutting frames 109. The limiting member is set on the fixed frame 104 and connected to the moving block 105. The limiting member can connect, support and directionally limit the movement of the moving block 105. The locking member is mounted on the movable block 105 and abuts against the connecting block 108. The locking member abuts against and pushes the abutment frame 109 to clamp and fix the air tube 103. This allows the operator to pull the movable block 105 outwards after the air tube 103 is connected to the external pipe 102, causing the tension spring 106 to stretch. Simultaneously, the locking member abuts against and pushes the abutment frame 109 to clamp and fix the air tube 103. After the abutment frame 109 abuts against the outside of the air tube 103, the operator releases the movable block 105, causing the tension spring 106 on the movable block 105 to deform and rebound.Thus, by using the abutment bracket 109 to clamp and fix the air tube 103, and in conjunction with the rebound pull of the tension spring 106, the air tube 103 can be more stably connected to the external pipe 102, thereby preventing the air tube 103 connected to the positioner body 101 from loosening or detaching from the external pipe 102 due to vibrations during equipment operation.

[0031] Secondly, the limiting cylinder 113 is fixedly connected to the fixed frame 104 and located on one side of the fixed frame 104; the sliding rod 114 is slidably connected to the limiting cylinder 113 and fixedly connected to the moving block 105, and located on the side of the limiting cylinder 113 close to the moving block 105. There are four limiting cylinders 113, which are welded to the corresponding four fixed frames 104. Each limiting cylinder 113 has a limiting groove. There are four sliding rods 114, which are slidably connected to the corresponding four limiting cylinders 113. The limiting cylinders 113 can connect, support, and directionally limit the sliding of the sliding rods 114. The four sliding rods 114 are welded to the corresponding four moving blocks 105, so that the movement of the sliding rods 114 can connect, support, and directionally limit the movement of the moving blocks 105.

[0032] Meanwhile, the screw 115 is threadedly connected to the moving block 105 and abuts against the connecting block 108; the rotating head 116 is fixedly connected to the screw 115 and located on one side of the screw 115. There are four screws 115, which are threadedly connected to the four corresponding moving blocks 105. There are four rotating heads 116, which are welded to the four corresponding screws 115. By rotating the rotating head 116, the screw 115 can be screwed into the moving block 105 and pass through the moving block 105 before abutting against the connecting block 108, thereby pushing the abutting frame 109 on the connecting block 108 toward the air tube 103, so that the abutting frame 109 can abut and clamp the outside of the air tube 103.

[0033] Finally, the rubber pad 110 is fixedly connected to the abutment frame 109 and located on one side of the abutment frame 109. The sealing gasket 111 is disposed on the external pipe 102 and located on the side of the external pipe 102 near the air tube 103. The anti-detachment block 112 is fixedly connected to the movable frame 107 and located on the side of the movable frame 107 near the movable block 105. There are four rubber pads 110, and the four rubber pads 110 are adhered to the four corresponding abutment frames 109. The rubber pads 110 can improve the abutment and clamping of the abutment frame 109. The friction on the outside of the air tube 103 is used to better fix the air tube 103. There are two sealing gaskets 111, which are bonded to the inside of the external pipe 102. The sealing gaskets 111 can improve the airtightness when the air tube 103 is connected to the external pipe 102. There are eight anti-detachment blocks 112, which are welded to the corresponding eight movable frames 107. The anti-detachment blocks 112 can prevent the movable frame 107 from moving off the movable block 105 when it moves on the movable block 105.

[0034] When using the intelligent valve positioner of this embodiment, after the air pipe 103 is connected to the external pipe 102, the operator pulls the moving block 105 outward to stretch the tension spring 106. At the same time, the locking member can abut against and push the abutment frame 109 to achieve abutment clamping and fixing of the air pipe 103. After the abutment frame 109 abuts against the outside of the air pipe 103, the operator releases the moving block 105, causing the tension spring 106 on the moving block 105 to deform and rebound. Thus, the abutment frame 109 abuts and clamps the air pipe 103, and the rebound pull of the tension spring 106 can more stably connect the air pipe 103 to the external pipe 102, thereby avoiding the air pipe 103 connected to the positioner body 101 from loosening or falling out of the external pipe 102 due to vibration caused by equipment operation.

[0038] The first fixing seat 201 is fixedly connected to the fixing frame 104 and the tension spring 106 respectively, and the first fixing seat 201 is located on the side of the fixing frame 104 near the tension spring 106; the second fixing seat 202 is fixedly connected to the moving block 105 and the tension spring 106 respectively, and the second fixing seat 202 is located on the side of the moving block 105 near the tension spring 106. There are four first fixing seats 201, and the four first fixing seats 201 are welded to one end of the corresponding four fixing frames 104 and four tension springs 106. The first fixing seats 201 can better fix one end of the tension spring 106 to the fixing frame 104. There are four second fixing seats 202, and the four second fixing seats 202 are welded to the other end of the corresponding four moving blocks 105 and four tension springs 106. The second fixing seats 202 can better fix the other end of the tension spring 106 to the moving block 105.
