Description

Technical Field

[0001] The utility model relates to the technical field of valve actuator installation, in particular to a movable steering bracket used for valve actuator installation. Background Art

[0002] Reactors are core equipment in industrial production, such as chemical, pharmaceutical, and food processing. Their valves are key components connecting the reactors to external piping systems, regulating material flow, pressure, and temperature to maintain reaction conditions. The quality of the connection between valves and actuators directly impacts the efficiency and safety of the entire system.

[0003] However, in the prior art, valve actuator brackets generally adopt a fixed design. This fixed bracket results in a rigid connection between the actuator and the valve, lacking the flexibility to adjust the angle. In actual installation environments, due to possible deviations in the relative positions of the reactor and the valve, or due to space constraints, it is often difficult to completely align the installation positions of the valve and actuator. In this case, because the fixed bracket cannot provide angle adjustment, the installer must perform extremely precise measurements and repeated adjustments to ensure that the axes of the actuator and the valve are completely aligned. This not only significantly increases the time required for installation, but also greatly increases the difficulty and complexity of installation. More seriously, if perfect alignment is not achieved during the installation process, or if slight displacement occurs during equipment operation due to factors such as vibration, thermal expansion and contraction, the actuator may come into physical contact with the reactor or other adjacent equipment during operation. This will not only affect the normal operation of the actuator, but may also cause wear or even damage to the equipment, thereby reducing the reliability and service life of the entire system.

[0004] In view of the above problems, the existing technology is in urgent need of improvement. Utility Model Content

[0032] Please also refer to Figures 1 to 3 An embodiment of the present application provides a movable steering bracket for mounting an actuator 12 on a valve 1. The movable steering bracket for mounting the actuator 12 on the valve 1 includes: a movable bracket 2, the movable bracket 2 including a fixed part 21, a rotating part 22 and a universal joint 25; the fixed part 21 is used to connect the valve 1, and the rotating part 22 is used to mount the actuator 12; the rotating part 22 is rotatably connected to the fixed part 21; one end of the universal joint 25 is connected to the output end of the actuator 12, and the other end is connected to the valve stem 13 of the valve 1.

[0033] The movable steering bracket for mounting actuator 12 on valve 1, provided in this embodiment of the application, rotates the angle between rotating member 22 and fixed member 21, allowing universal joint 25 to transmit the rotation angle of actuator 12 to valve stem 13. This compensates for axis misalignment between the two and ensures smooth power transmission. This effectively resolves axis misalignment that may occur when installing valve 1 and actuator 12, significantly reducing installation difficulty and time, and avoiding wear and damage to equipment caused by a rigid connection, thereby improving system reliability and service life.

[0034] In this embodiment, a movable groove 27 is provided on the rotating member 22, and the fixed member 21 and the rotating member 22 are connected and locked by an axial nut 23 serving as a rotation center and a limit nut 24 passing through the movable groove 27; a first connecting groove 211 is provided on the fixed member 21 for the valve stem 13 to pass through; and a second connecting groove 221 is provided on the rotating member 22 for the output end of the actuator 12 to pass through.

At the same time, the first connecting groove 211 and the second connecting groove 221 can ensure that the valve stem 13 and the output end of the actuator 12 have sufficient space and a correct path inside the bracket for connection, thereby avoiding interference and simplifying the overall assembly process.

When the rotating member 22 rotates, the rotating member 22 can be smoothly and accurately adjusted around a fixed center. Meanwhile, the movement and locking of the limiting nut 24 in the arc-shaped slot ensure the stability and reliability of the adjusted position.

[0040] In the embodiment, the axial nut 23 and the limiting nut 24 pass through the first side plate and the second side plate.

[0041] In this way, the passing positions of the axial nut 23 and the limiting nut 24 are clearly defined, ensuring their fixing and limiting effects on the side plates, thereby realizing the reliable rotation and locking functions of the rotating member 22.

[0042] In the embodiment, the first communication slot 211 is arranged on the bottom plate; and the second communication slot 221 is arranged on the top plate.

[0043] In this way, the communication slots are arranged on the bottom plate and the top plate, so that the valve rod 13 and the actuator 12 output end can vertically pass through the bracket, thereby optimizing the space layout and making the connection more direct and compact.

[0044] In the embodiment, the axial hole 26 is arranged on the first side plate and the second side plate, and the movable slot 27 is arranged on the second side plate.

[0045] In this way, the positions of the axial hole 26 and the movable slot 27 on the side plates are accurately defined, ensuring the stability of the rotating axis of the rotating member 22, and the movable slot 27 can effectively guide and limit the rotation range, thereby realizing accurate angle adjustment.

[0046] In the embodiment, a connecting flange 11 is arranged on the valve 1, and the fixed member 21 is installed on the connecting flange 11.

[0047] Such an arrangement provides a standardized connection method, so that the bracket can be easily and quickly installed with the valve 1 with the connecting flange 11, thereby improving versatility and installation efficiency.

[0048] In this embodiment, the valve 1 is a ball valve, a butterfly valve, a plug valve, etc.

[0049] Such a setting clarifies that the bracket is suitable for common ball valves, butterfly valves, plug valves, etc., expands its application range, and meets the installation requirements of different types of valves 1 in industrial production.

[0050] In this embodiment, the actuator 12 is a pneumatic actuator 12, an electric actuator, a handle rotation, a hand wheel rotation, etc.

[0051] Such a setting clarifies that the bracket is suitable for rotation modes such as pneumatic actuator 12, electric actuator, handle rotation or handwheel rotation, and further illustrates its wide compatibility and ability to adapt to actuators 12 with various operating modes. By selecting the appropriate type of actuator 12, the control mode of the valve 1 can be flexibly adjusted according to actual application requirements, thereby improving the adaptability and reliability of the valve control system.

At the same time, the actuator 12 is installed on the rotating member 22, and the output end of the actuator 12 passes through the second connecting groove 221 on the rotating member 22, so that one end of the universal joint 25 is connected to the output end of the actuator 12, and the other end of the universal joint 25 is connected to the valve stem 13, so that the rotation of the actuator 12 drives the valve stem 13 to rotate, thereby controlling the opening and closing of the valve 1. After adjusting the angle of the actuator 12, tighten the axis nut 23 and the limit nut 24 to avoid later angle deviation. In addition, the actuator 12 can be a pneumatic actuator 12, an electric actuator or a manual adjustment method to adjust the actuator 12 for controlling the opening and closing mode of the valve 1.
