Description

Technical Field

[0001] This utility model relates to the field of valve controller technology, specifically to a gas valve controller installation structure. Background Technology

[0002] In gas transmission systems, gas valve controllers are core components for automatically opening and closing valves and ensuring safe gas usage. The rationality of their installation structure directly affects the controller's operational stability, installation efficiency, and adaptability. However, existing gas valve controller installation structures still have many shortcomings in practical applications, making it difficult to meet diverse installation needs and safety standards. Specific problems are as follows.

[0003] 1. Poor versatility and limited compatibility: The length and thickness of the valve arm vary between different brands and specifications of valves. Traditional installation structures are mostly designed with fixed dimensions, and the matching degree between the valve arm clamp and the valve arm is limited by the preset specifications, making it impossible to flexibly adjust to adapt to valves of different sizes.

[0004] 2. Fixed installation height and low connection accuracy: In traditional installation structures, the connection position between the controller and the pipeline is fixed, and the height of the controller cannot be flexibly adjusted after installation. If there are deviations in the on-site pipeline layout or when valves of different heights are replaced, interference may easily occur between the controller and the valve arm or the pipeline.

[0005] 3. The transmission connection is prone to loosening, posing a significant safety hazard: The transmission connection between the controller and the valve arm relies on the cooperation between the arm clamp and the output shaft of the drive motor. Traditional structures often use a single bolt and nut for fixing, lacking reliable positioning and anti-loosening design. During long-term use, factors such as gas pipeline vibration and changes in ambient temperature can easily cause the nut to loosen, leading to misalignment in the connection between the arm clamp, the drive motor output shaft, and the valve arm. This can even prevent the valve arm from moving, causing the valve to malfunction and posing a safety risk of gas leakage.

[0006] There is an urgent need for an installation structure that is flexible, adaptable, reliable, and easy to install to address the aforementioned technical pain points and improve the installation quality and operational safety of gas valve controllers. Therefore, an installation structure for gas valve controllers is proposed. Summary of the Invention

[0009] A clamp is installed on the outside of the pipe. Both threaded rods pass through the folded plates on both sides of the clamp. An adjusting nut for adjusting the height of the controller body and a second fixing nut for fixing the position of the clamp are threaded on the threaded rods. The adjusting nut is located above the clamp, and the second fixing nut is located below the clamp.

[0010] An adjustable-length rotary arm clamp is installed on the other side of the lower surface of the controller body, and the rotary arm clamp is connected to the output shaft of the drive motor inside the controller body.

[0011] Preferably, a first fixing nut is also installed on the threaded rod to fix the position of the threaded rod, and the first fixing nut is located on the lower surface of the support frame.

[0012] Preferably, the rotary arm clamp includes a fixed plate, an extension groove is provided on the fixed plate, and a movable plate is provided at one end of the fixed plate. The movable plate is adjustablely mounted on the extension groove by bolts.

[0013] Preferably, one end of the movable plate is provided with an adjustment groove, and two clamping arms are adjustablely installed on the adjustment groove by bolts. The two clamping arms are located on both sides of the valve rotating arm of the valve body.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a gas valve controller installation structure, including a pipeline 1 and a valve body 2. The valve body 2 is fixedly installed on the pipeline 1 and is used to control the on / off of gas in the pipeline 1. The controller body 3 is used to drive the opening and closing action of the valve body 2. A support frame 7 is bolted to one side of the lower surface of the controller body 3. The support frame 7 is a metal plate structure and is used to install threaded rods 5. Two threaded rods 5 are installed through the support frame 7. A semi-circular clamp 4 is fitted on the outside of the pipeline 1. The clamp 4 has integrally formed folded plates with through holes on both sides, and the two threaded rods 5 pass through the through holes of the folded plates on both sides of the clamp 4.

[0026] The threaded rod 5 is threadedly connected to an adjusting nut 9 and a second fixing nut 10. The adjusting nut 9 is located above the clamp 4. By rotating the adjusting nut 9, the length of the threaded rod 5 between the clamp 4 and the controller body 3 can be controlled, thereby adjusting the installation height of the controller body 3. The second fixing nut 10 is located below the clamp 4. After tightening, the clamp 4 can be clamped to the outside of the pipe 1. At the same time, it can also fix the position of the threaded rod 5, preventing the clamp 4 from loosening and the threaded rod 5 from moving freely.

[0027] An adjustable-length rotary arm clamp 6 is installed on the other side of the lower surface of the controller body 3. The rotary arm clamp 6 is used to connect the valve arm of the valve body 2, and the rotary arm clamp 6 is connected to the output shaft of the drive motor inside the controller body 3, so that the drive motor can drive the valve arm to rotate through the rotary arm clamp 6 to realize the automatic opening and closing of the valve.

[0028] like Figure 3 and Figure 4 As shown: A first fixing nut 8 is also threaded onto the threaded rod 5. The first fixing nut 8 is located on the lower surface of the support frame 7 and fits tightly against the lower surface of the support frame 7. Tightening the first fixing nut 8 can fix the threaded rod 5 to the support frame 7, preventing the threaded rod 5 from rotating or shifting during use and ensuring the stability of the overall structure.

[0029] like Figure 5 and Figure 6 As shown: The rotary arm clamp 6 includes a fixed plate 61, on which two elongated extension slots 62 are formed along the length direction. A movable plate 63 is provided at one end of the fixed plate 61. One end of the movable plate 63 is adjustablely mounted on the extension slots 62 by bolts. The bolts pass through the movable plate 63 and the extension slots 62. Loosening the bolts allows the movable plate 63 to move along the extension slots 62, adjusting the overlap length between the movable plate 63 and the fixed plate 61, thereby changing the overall length of the rotary arm clamp 6 to accommodate valve arms of different sizes.

[0030] like Figure 5 and Figure 6 As shown: The movable plate 63 has an adjustment groove 14 at the end away from the fixed plate 61. Two clamping arms 11 are adjustablely mounted on the adjustment groove 14 by two independent bolts for clamping the valve arm. The two clamping arms 11 are located on both sides of the valve arm of the valve body 2. Loosening the bolts can adjust the distance between the two clamping arms 11 along the adjustment groove 14, so that the valve arm clamp 6 can be adapted to different valve arms, improving versatility.

[0031] like Figure 6As shown: Multiple circular limiting holes 611 are evenly distributed on the end of the fixed plate 61 away from the extension groove 62. The limiting holes 611 are used for positioning in conjunction with the limiting posts 122. A cylindrical connecting post 12 is keyed to the end of the output shaft of the drive motor inside the controller body 3. The connecting post 12 is coaxially arranged with the output shaft. A circular connecting plate 121 is welded to the outside of the connecting post 12. Multiple cylindrical limiting posts 122 are evenly welded along the circumference of the side of the connecting plate 121 facing the fixed plate 61. The number of limiting posts 122 is the same as the number of limiting holes 611, and the dimensions of the multiple limiting posts 122 and the multiple limiting holes 611 are compatible. Inserting the limiting posts 122 into the corresponding limiting holes 611 enables rapid positioning of the fixed plate 61 and the connecting plate 121, ensuring the coaxiality of the rotary arm clamp 6 and the output shaft of the drive motor, and avoiding transmission deviation.

[0032] like Figure 6 As shown: The outer side of the connecting post 12 is provided with an external thread, which extends from one side of the connecting plate 121 to the end of the connecting post 12. A third fixing nut 13 is connected to the outer thread of the connecting post 12. The third fixing nut 13 is located on the side of the fixing plate 61 away from the connecting plate 121. Tightening the third fixing nut 13 can firmly press the fixing plate 61 onto the connecting plate 121, thereby achieving a fixed connection between the fixing plate 61 and the connecting post 12, preventing the fixing plate 61 from separating from the connecting plate 121 during transmission, and ensuring transmission stability.

[0033] Working principle: During installation, first, the clamp 4 is placed on the outside of the pipe 1. Then, the support frame 7 on one side of the lower surface of the controller body 3 is assembled and fixed with the threaded rod 5. Subsequently, the two threaded rods 5 pass through the folded plates on both sides of the clamp 4, initially establishing the connection frame between the controller body 3 and the pipe 1. If it is necessary to adjust the height of the controller body 3 to match the valve arm position of the valve body 2, the adjusting nut 9 located above the clamp 4 can be rotated. By changing the position of the adjusting nut 9 on the threaded rod 5, the length of the threaded rod 5 between the clamp 4 and the controller body 3 can be controlled, thereby driving the support frame 7 and the controller body 3 to move up and down, realizing the height adjustment. After the height is determined, the second fixing nut 10 located below the clamp 4 is tightened to make the clamp 4 tightly clamp the pipe 1, restricting the position of the clamp 4 and the threaded rod 5, and preventing displacement during use.

[0034] To ensure precise installation of the rotary arm clamp 6 with valve bodies 2 of varying valve arm lengths, its overall length must first be adjusted. Loosen the bolts between the moving plate 63 and the fixed plate 61, and push the moving plate 63 along the extension groove 62 to change the overlap length between the fixed plate 61 and the moving plate 63 until the length of the rotary arm clamp 6 matches the valve arm. Then, loosen the bolts at the adjustment groove 14 on the moving plate 63, adjust the distance between the two clamping arms 11 along the adjustment groove 14, so that the clamping arms 11 fit against both sides of the valve arm of the valve body 2. Finally, tighten the bolts to secure the clamping arms 11, completing the fitting connection between the rotary arm clamp 6 and the valve arm.

[0035] To prevent the rotary arm clamp 6 from failing to rotate effectively due to a loose nut, firstly, the multiple limiting pins 122 on the connecting plate 121 are precisely inserted into the multiple limiting holes 611 on the fixing plate 61. The cooperation between the limiting pins 122 and the limiting holes 611 ensures coaxial positioning of the fixing plate 61 and the connecting plate 121, preventing transmission deviation. Then, the third fixing nut 13 on the outside of the connecting pin 12 is tightened, pressing firmly against the side of the fixing plate 61 away from the connecting plate 121, thus firmly fixing the fixing plate 61 to the connecting plate 121. When the drive motor operates, its output shaft drives the fixing plate 61 to rotate via the connecting pin 12 and the connecting plate 121. The fixing plate 61 then drives the clamp arm 11 via the moving plate 63. Finally, the clamp arm 11 drives the valve arm of the valve body 2 to rotate, achieving automatic on / off of the gas valve and ensuring a stable and effective transmission process.
