Description

Technical Field

[0001] This utility model relates to the technical field of valve maintenance auxiliary devices, and in particular to a pneumatic butterfly valve maintenance auxiliary device. Background Technology

[0002] Pneumatic butterfly valves are commonly used control devices in industrial pipeline systems and are widely used in chemical, petroleum, metallurgical, and water treatment fields to regulate the flow of media or cut off fluids. However, traditional maintenance methods for pneumatic butterfly valves have many problems. On the one hand, it is difficult to accurately position and stably fix the butterfly valve during installation and disassembly, which is inconvenient for maintenance personnel and can easily lead to low maintenance efficiency. Furthermore, shaking may cause damage to parts or maintenance errors. On the other hand, there is a lack of effective auxiliary devices to provide stable support and adjustment for butterfly valve drive components and other parts. It is difficult to adapt to different specifications of butterfly valves during maintenance, which increases the difficulty of maintenance and safety hazards. Utility Model Content

[0003] The main purpose of this utility model is to provide a pneumatic butterfly valve maintenance auxiliary device, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A pneumatic butterfly valve maintenance auxiliary device includes a fixed platform, an installation frame fixedly connected to the upper end of the fixed platform, sliding grooves provided at the upper front and upper rear ends of the installation frame, two support plates fixedly connected to the middle of the upper end of the installation frame, a driving component placed on the upper end of the two support plates, a butterfly valve body fixedly connected to the upper end of the driving component, and a moving device fixedly connected to the lower left and lower right ends of the installation frame, with two sets of snap-fit ​​butterfly valve assemblies provided at the upper ends of the two moving devices.

[0006] Preferably, the moving device includes an electric push rod, which is fixedly connected to the left end of the mounting frame. The output end of the electric push rod passes through the lower left end of the mounting frame and is fixedly connected to a moving plate. The lower front end and the lower rear end of the moving plate are both fixedly connected to connecting blocks, and the lower ends of the two connecting blocks that are close to each other are both fixedly connected to sliders.

[0007] Preferably, the two mobile devices are arranged in a left-right mirror image configuration.

[0008] Preferably, the lower end face of the movable plate is in close contact with the upper end face of the fixed platform.

[0009] Preferably, the electric push rod is slidably connected to the fixed platform through two connecting blocks, and the two sliders are slidably connected in two grooves respectively.

[0010] Preferably, the snap-fit ​​butterfly valve assembly includes a mounting plate, which is fixedly connected to the upper end of a movable plate. A left limiting rod and a right limiting screw rod are fixedly connected to the upper left and upper right parts of the mounting plate, respectively. A horizontal push rod is movably connected to the upper outer surface of the left limiting rod and the right limiting screw rod. A spring is fixedly connected to the lower right part of the mounting plate. A top block is fixedly connected to the end of the spring away from the mounting plate. The top block and the spring are movably connected to the right limiting screw rod. The top block is located below the push plate. A locking nut is movably connected to the upper outer surface of the right limiting screw rod.

[0011] Preferably, the right limiting screw rod is located above the push plate.

[0012] Preferably, the two sets of horizontally distributed snap-fit ​​butterfly valve assemblies are arranged in a left-right mirror image, and the ends of the four push plates that are close to each other are tightly abutted against the end face of the drive component.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, the moving device is fixed to the mounting frame by an electric push rod. Its output end drives the moving plate to slide on the fixed platform. The cooperation between the connecting block and the slider allows the slider to slide stably in the groove. The left and right mirror distribution design ensures the synchronicity and stability of the movement on both sides. This device can accurately adjust the position of the butterfly valve drive component and valve body to achieve precise positioning during maintenance. During maintenance operations, the moving plate can drive the butterfly valve to move smoothly and avoid shaking, providing maintenance personnel with a convenient and stable operating environment, effectively preventing parts from being damaged due to shaking, greatly improving maintenance efficiency and accuracy, and reducing the probability of maintenance errors.

[0015] 2. In this utility model, a flexible clamping system is constructed by connecting the mounting plate and the moving plate. The left limiting rod and the right limiting screw rod, together with the horizontal top rod, form a stable frame structure, which can initially limit the range of motion of the push plate. The combination of the spring and the top block gives the push plate an elastic clamping force, which can not only firmly clamp the driving component, but also avoid damage caused by hard compression. The right limiting screw rod and the locking nut realize the fine adjustment of the position of the push plate to adapt to different specifications of butterfly valve driving components. The two sets of components distributed in mirror on the left and right form a ring-shaped clamping of the driving component from multiple directions, ensuring its stability during maintenance. This greatly improves the adaptability of the device to butterfly valves of different specifications and the safety and convenience of maintenance operations. Attached Figure Description

[0025] A pneumatic butterfly valve maintenance auxiliary device includes a fixed platform 1, an installation frame 2 fixedly connected to the upper end of the fixed platform 1, a sliding groove 3 provided at the upper front and upper rear ends of the installation frame 2, two support plates 4 fixedly connected to the middle of the upper end of the installation frame 2, a driving component 5 jointly placed at the upper end of the two support plates 4, a butterfly valve body 6 fixedly connected to the upper end of the driving component 5, and a moving device 7 fixedly connected to the lower left and lower right ends of the installation frame 2, with two sets of snap-fit ​​butterfly valve assemblies 8 provided at the upper ends of the two moving devices 7.

[0026] In this embodiment, the moving device 7 includes an electric push rod 71, which is fixedly connected to the left end of the mounting frame 2. The output end of the electric push rod 71 passes through the lower left end of the mounting frame 2 and is fixedly connected to a moving plate 72. The lower front end and the lower rear end of the moving plate 72 are both fixedly connected to connecting blocks 73. The lower ends of the two connecting blocks 73 that are close to each other are both fixedly connected to sliders 74. The two moving devices 7 are distributed in a left-right mirror image. The lower end surface of the moving plate 72 is in close contact with the upper end surface of the fixed platform 1. The electric push rod 71 is slidably connected to the fixed platform 1 through the two connecting blocks 73. The two sliders 74 are slidably connected in the two sliding grooves 3 respectively.

[0027] Through the above scheme: the electric push rod 71 is fixed to the mounting frame 2, and its output end drives the moving plate 72 to slide on the fixed platform 1. The connecting block 73 cooperates with the slider 74, and the slider 74 slides in the slide groove 3 to ensure that the moving plate 72 moves smoothly. The two moving devices 7, which are distributed in a mirror image on the left and right, cooperate with the snap-fit ​​butterfly valve assembly 8 to accurately adjust and clamp the driving component 5 and the butterfly valve body 6. During maintenance, the electric push rod 71 can adjust the position of the moving plate 72 as needed to achieve precise positioning of the butterfly valve, reduce shaking, make the operation of maintenance personnel more convenient, effectively avoid damage to parts, improve maintenance efficiency and accuracy, and reduce maintenance errors.

[0028] In this embodiment, the snap-fit ​​butterfly valve assembly 8 includes a mounting plate 81, which is fixedly connected to the upper end of the movable plate 72. The upper left and upper right parts of the mounting plate 81 are respectively fixedly connected to a left limiting rod 82 and a right limiting screw rod 85. The upper outer surfaces of the left limiting rod 82 and the right limiting screw rod 85 are interpenetratingly connected to a horizontal push rod 83. The lower right part of the mounting plate 81 is fixedly connected to a spring 86. The end of the spring 86 away from the mounting plate 81 is fixedly connected to a top block 87. The top block 87 and the spring 86 are interpenetratingly connected to the right limiting screw rod 85. The top block 87 is located below the push plate 84. The upper outer surface of the right limiting screw rod 85 is threadedly connected to a locking nut 88. The right limiting screw rod 85 is located above the push plate 84. The two sets of snap-fit ​​butterfly valve assemblies 8 distributed laterally are mirror images of each other. The ends of the four push plates 84 that are close to each other are tightly abutted against the end face of the drive member 5.

[0029] With the above solution: the mounting plate 81 is fixed on the movable plate 72, and an adjustable frame is formed by the left limit rod 82, the right limit screw rod 85 and the horizontal top rod 83. The spring 86 and the top block 87 provide elastic support. The right limit screw rod 85, together with the locking nut 88, can adjust the position of the push plate 84. The two sets of snap-fit ​​butterfly valve assemblies 8 are distributed in a mirror image on the left and right sides, so that the four push plates 84 can press against the drive component 5 from different directions. During maintenance, different specifications of butterfly valves can be adapted by adjusting the right limit screw rod 85 and the locking nut 88. The spring 86 provides buffering to ensure stable support, reduce maintenance difficulty and safety hazards, and improve maintenance adaptability.

[0030] It should be noted that this utility model is a pneumatic butterfly valve maintenance auxiliary device. During use, firstly, during maintenance, the butterfly valve body 6 is fixed to the driving component 5, and the entire assembly is placed on the support plate 4. The electric push rod 71 is activated, and its output end pushes the moving plate 72 to slide along the fixed platform 1. The slider 74 slides synchronously within the slide groove 3, ensuring smooth movement. The left and right mirror-distributed moving devices 7 drive the snap-fit ​​butterfly valve assembly 8 to move towards or away from each other, achieving initial positioning of the driving component 5. Then, when adjusting the snap-fit ​​butterfly valve assembly 8, the device is released... The locking nut 88 and the push plate 84 elastically press against the drive component 5 under the action of the spring 86 and the top block 87. By rotating the right limit screw rod 85 and the locking nut 88, the position of the push plate 84 is finely adjusted so that the four push plates 84 firmly clamp the drive component 5 from different directions. Among them, the spring 86 provides buffer to avoid damage to the parts by hard squeezing. Therefore, precise positioning is achieved by the moving device 7. The snap-fit ​​butterfly valve assembly 8 is adapted to butterfly valves of different specifications, which solves the problems of difficult positioning and unstable support in traditional maintenance, and significantly improves maintenance efficiency and safety.
