Description

A combined valve actuator Technical Field

[0001] This utility model relates to the field of valve actuator technology, specifically a combined valve actuator. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the conveyed medium. Valves can be controlled by various transmission methods, such as manual, electric, hydraulic, pneumatic, and turbine drive. Electric valve actuators are devices used to automatically control valves in fluid pipelines, and they play an important role in industrial automation and process control.

[0003] Existing actuator support structures are mostly fixed designs, which are difficult to adapt to complex installation scenarios. For example, when the actuator needs to be installed close to the wall or the ground, the pipeline will vibrate during use. Furthermore, traditional support components cannot adjust the angle or height and cannot be used to support different installation scenarios. Therefore, they are prone to displacement due to pipeline vibration or external impact, and may even cause the connection to loosen. To address this, a combined valve actuator is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a combined valve actuator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined valve actuator, comprising a valve body, an actuator, and a support assembly. The support assembly includes a mounting rod, a rotating plate slidably connected to the mounting rod, a threaded rod rotatably connected to the rotating plate, a horizontal plate threadedly connected to the threaded rod, support legs on both sides of the bottom of the horizontal plate, a base plate at the bottom of the support legs, a limiting groove on the rotating plate, and a handle on the threaded rod, the handle being located above the horizontal plate.

[0007] As a further preferred embodiment of this technical solution: the rotating plate adjusts its angle through a fixing component, the fixing component including a first positioning hole and a second positioning hole arranged at one end of the mounting rod, the through cylinder having a through hole, and a pin slidingly connected through the through hole.

[0008] As a further preferred embodiment of this technical solution: the valve body and the actuator are fixedly connected by bolts, the bolts are provided in four sets, and a gasket is provided at the contact point between the bolts and the actuator.

[0009] As a further preferred embodiment of this technical solution: the support assembly is provided in two sets and distributed on both sides of the actuator, the horizontal plate slides through the limiting groove, the support leg slides through the bottom of the rotating plate, and the rotating plate rotates and slides on the mounting rod.

[0010] As a further preferred embodiment of this technical solution: the mounting rod passes through the through-tube and one end of the mounting rod is located inside the insertion hole, the insertion hole does not pass through the fixing plate, and the rotating plate is located between the two sets of nuts.

[0011] As a further preferred embodiment of this technical solution: the first positioning hole and the second positioning hole are arranged perpendicularly and penetrate the mounting rod, the through hole corresponds to the positions of the first positioning hole and the second positioning hole, and the pin penetrates the first positioning hole and the second positioning hole.

The support assembly includes a mounting rod 301, a rotating plate 302 slidably connected to the mounting rod 301, a threaded rod 303 rotatably connected to the rotating plate 302, a horizontal plate 304 threadedly connected to the threaded rod 303, support legs 305 respectively provided on both sides of the bottom of the horizontal plate 304, a base plate 306 provided at the bottom of the support legs 305, a limiting groove 307 provided on the rotating plate 302, and a handle 308 provided on the threaded rod 303, with the handle 308 located above the horizontal plate 304.

[0023] Among them, the rotating plate 302, the horizontal plate 304, and the bottom plate 306 are all made of stainless steel, and the rotating plate 302 is U-shaped.

[0024] Example 2

[0025] A combined valve actuator includes a rotating plate 302 connected to an actuator 2 via a mounting assembly. The mounting assembly includes two sets of fixing plates 401 fixedly connected to the actuator 2. One set of fixing plates 401 has a through-tube 402, and the other set has an insertion hole 403. Threaded structures 404 are provided on both sides of the mounting rod 301, with nuts 405 threaded onto each threaded structure 404. The rotating plate 302's angle is adjustable via the fixing assembly. The fixing assembly includes a first positioning hole 501 and a second positioning hole 502 located at one end of the mounting rod 301. The through-tube 402 has a through hole 503, through which a pin 504 is slidably connected. The valve body 1 and actuator 2 are fixedly connected by bolts 701, with four sets of bolts 701. A washer 702 is provided at the contact point between the bolts 701 and the actuator 2. Two sets of support assemblies are provided on both sides of the actuator 2. A horizontal plate 304 slides through a limiting groove 307. The support leg 305 slides through the bottom of the rotating plate 302. The rotating plate 302 rotates and slides on the mounting rod 301. The mounting rod 301 passes through the through cylinder 402, and one end of the mounting rod 301 is located in the insertion hole 403. The insertion hole 403 does not pass through the fixing plate 401. The rotating plate 302 is located between the two sets of nuts 405. The length of the mounting rod 301 is greater than the distance between the two sets of fixing plates 401. The top of the rotating plate 302 has two grooves at the positions where it fits with the nuts 405. The first positioning hole 501 and the second positioning hole 502 are set perpendicularly and pass through the mounting rod 301. The through hole 503 corresponds to the positions of the first positioning hole 501 and the second positioning hole 502. The pin 504 passes through the first positioning hole 501 and the second positioning hole 502. The first positioning hole 501 and the second positioning hole 502 are located on the outside of the fixing plate 401. The through cylinder 402 is located on the outside of the fixing plate 401. The through hole 503 is located at the top and bottom of the through cylinder 402.

[0026] Working principle: The operator places the gasket 702 on the actuator 2, and then uses four sets of bolts 701 to fix the valve body 1 to the actuator 2. Then the valve body 1 is installed on the pipeline. Two sets of support components are installed as needed. Nuts 405 are placed on both sides of the top of the rotating plate 302. Then the installation rod 301 is passed through the through cylinder 402 and through the rotating plate 302.

[0027] When inserting the mounting rod 301, it is necessary to rotate the mounting rod 301 so that it can pass through the two sets of nuts 405 until one end of the mounting rod 301 is inserted into the insertion hole 403. Tighten the two sets of nuts 405 on the threaded structure 404 to clamp and fix the rotating plate 302. Rotate the rotating plate 302 on the side closest to the wall by 90 degrees. Then insert the pin 504 into the through hole 503 and into the corresponding first positioning hole 501 or second positioning hole 502. Manually turn the handle 308 to drive the threaded rod 303 to rotate, so that the horizontal plate 304 slides in the limiting groove 307 and pushes the support leg 305 and the base plate 306 to move, thereby making the base plate 306 fit against the ground or wall to support the valve body 1 and enhance the stability during use.
