Description

Technical Field

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

[0002] The actuator is an essential component of an automatic control system. Its function is to receive control signals from the controller, change the magnitude of the controlled medium, and thus maintain the controlled variable at the required value or within a certain range.

[0003] Existing valve actuators are typically welded to the top of the valve using a mounting bracket. The actuator has a rotating connecting shaft at its bottom, which is then welded to the valve stem after the actuator is fixed in place. The actuator's controller receives a control signal and drives the connecting shaft via a motor, thereby controlling the valve's opening and closing and achieving flow regulation. This current installation method makes disassembly and adjustment difficult, leading to significant inconvenience for future maintenance. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a valve actuator that is easy to install and facilitates subsequent disassembly and maintenance.

[0005] This utility model is achieved through the following technical solution: a valve actuator that is easy to install, comprising an actuator body, a fixed bracket, and a connector. The fixed bracket includes a fixed plate, an upper clamping plate and a lower clamping plate distributed vertically, a clamping hoop, and a connecting rod. The fixed plate is fixed to the bottom of the actuator body. A clamping space for holding the valve is formed between the upper clamping plate and the lower clamping plate. The upper clamping plate and the lower clamping plate are detachably connected by the clamping hoop. The fixed plate is fixedly connected to the upper clamping plate by the connecting rod. The fixed plate has a first through hole for the connecting shaft of the actuator body to pass through, and the upper clamping plate has a second through hole for the valve stem of the valve to pass through. The connecting shaft and the valve stem are connected by the connector.

[0006] In this design, the actuator body is connected to the valve by upper and lower clamping plates, which are then secured with clamps to firmly fix the actuator body to the valve. The actuator body's connecting shaft is connected and fixed to the valve stem via a connector, allowing the actuator body to drive the valve stem's rotation. The actuator body is detachably connected to the valve via a fixed bracket, and the connecting shaft is detachably connected to the valve stem via a connector, facilitating installation and subsequent disassembly and maintenance.

[0007] As an optimization, both the upper and lower clamping plates are arc-shaped structures. This optimization makes the shapes of the upper and lower clamping plates fit the outer wall of the valve more closely, thereby improving the clamping effect.

[0008] As an optimization, the arc-shaped structure is a minor arc. In this optimized solution, the upper and lower clamping plates are set as minor arcs, with an arc length less than the semicircle of the valve, thus creating a gap between the ends of the upper and lower clamping plates. After being tightened by the clamping clamp, the clamping effect between the upper and lower clamping plates is better.

[0009] As an optimization, rubber gaskets are fixed to the inner walls of both the upper and lower clamping plates. This optimization scheme uses rubber gaskets to increase friction with the outer wall of the valve, making the fixing effect of the fixed bracket more stable, and at the same time, the elasticity of the rubber gaskets protects the valve.

[0010] As an optimization, two clamps are provided, each clamping one end of the clamping space. This optimization improves the clamping effect between the upper and lower clamping plates.

[0011] As an optimization, the fixing plate is fixed to the actuator body by bolts. This optimized solution facilitates the fixing of the bracket to the actuator body and makes assembly and disassembly convenient.

[0012] As an optimization, one end of the connector has a first countersunk groove adapted to the shape of the connecting shaft, and the other end has a second countersunk groove adapted to the shape of the valve stem. In this optimized design, the connector is fixed to the connecting shaft by insertion through the first countersunk groove and to the valve stem by insertion through the second countersunk groove, thereby connecting the connecting shaft to the valve and facilitating disassembly.

[0013] As an optimization, the connecting shaft is rectangular in shape, while the valve stem is oval. This optimized design uses different shapes for the connecting shaft and valve stem to facilitate connector positioning.

[0014] The beneficial effects of this utility model are as follows: When the actuator body is connected to the valve, the valve is surrounded and clamped by the upper and lower clamping plates, and then the upper and lower clamping plates are tightly fixed by a clamp, thereby fixing the actuator body to the valve. The connecting shaft of the actuator body is connected and fixed to the valve stem of the valve through a connector, thereby enabling the actuator body to drive the rotation of the valve stem. The actuator body is detachably connected to the valve through a fixed bracket, and the connecting shaft is detachably connected to the valve stem through a connector, which is convenient for installation and easy for subsequent disassembly and maintenance.

[0026] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0027] like Figures 1-6 As shown, an easy-to-install valve actuator includes an actuator body 1, a fixed bracket 3, and a connector 5. The fixed bracket 3 includes a fixed plate 31, an upper clamping plate 33 and a lower clamping plate 34 distributed vertically, a clamping clamp 35, and a connecting rod 32.

[0028] Specifically, the fixing plate 31 is fixed to the bottom of the actuator body 1. The fixing plate 31 is a rectangular plate. The fixing plate 31 is fixed to the actuator body 1 by bolts, which facilitates the fixing of the bracket 3 to the actuator body 1 and makes it easy to disassemble and assemble.

[0029] The upper clamping plate 33 and the lower clamping plate 34 form a clamping space for holding the valve 2. The upper clamping plate 33 and the lower clamping plate 34 are detachably connected by a clamping hoop 35. Both the upper clamping plate 33 and the lower clamping plate 34 are arc-shaped structures, and the arc-shaped structure is a minor arc. The arc-shaped upper clamping plate 33 and the lower clamping plate 34 fit more closely to the outer wall of the valve 2, thereby improving the clamping effect; and the arc-shaped structure is set as a minor arc, the arc length of which is less than the semicircle of the valve 2, so that there is a gap between the ends of the upper clamping plate 33 and the lower clamping plate 34. After being clamped by the clamping hoop 35, the clamping effect between the upper clamping plate 33 and the lower clamping plate 34 is better. In this embodiment, two clamping hoop 35s are provided, and the two clamping hoop 35s respectively clamp the two ends of the clamping space to improve the clamping effect of the upper clamping plate 33 and the lower clamping plate 34.

[0030] Preferably, rubber gaskets 4 are fixed to the inner walls of both the upper clamping plate 33 and the lower clamping plate 34. By setting the rubber gaskets 4, the friction with the outer wall of the valve 2 is increased, making the fixing effect of the fixing bracket 3 more stable; at the same time, the elasticity of the rubber gaskets 4 protects the valve 2.

[0031] Specifically, the fixing plate 31 is fixedly connected to the upper clamping plate 33 via connecting rods 32. In this embodiment, two connecting rods 32 are symmetrically fixedly connected to the bottom of the fixing plate 31. The connecting rods 32 extend vertically, and their upper and lower ends are fixedly connected to the fixing plate 31 and the upper clamping plate 33, respectively. The fixing plate 31 and the upper clamping plate 33 form an integral structure through the connecting rods 32.

[0032] The fixed plate 31 has a first through hole 36 through which the connecting shaft 11 of the actuator body 1 passes, and the upper clamping plate 33 has a second through hole 3 through which the valve stem 21 of the valve 2 passes. The connecting shaft 11 and the valve stem 21 are connected by the connector 5.

[0033] When the actuator body 1 is connected to the valve 2, the valve 2 is surrounded and clamped by the upper clamping plate 33 and the lower clamping plate 34, and then the upper clamping plate 33 and the lower clamping plate 34 are tightly fixed by the clamping clamp 35, thereby fixing the actuator body 1 to the valve 2. The connecting shaft 11 of the actuator body 1 is connected and fixed to the valve stem 21 of the valve 2 through the connecting head 5, so that the actuator body 1 can drive the rotation of the valve stem 21. The actuator body 1 is detachably connected to the valve 2 through the fixing bracket 3, and the connecting shaft 11 is detachably connected to the valve stem 21 through the connecting head 5, which is convenient for installation and easy for later disassembly and maintenance.

[0034] Specifically, the connecting shaft 11 has a rectangular shape, and the valve stem 21 has a flattened oval shape. By setting the connecting shaft and valve stem to different shapes, the positioning of the connector is convenient. One end of the connector 5 has a first recess 51 that matches the shape of the connecting shaft 11, and the other end has a second recess 52 that matches the shape of the valve stem 21. The connector 5 is a cylindrical structure. The first recess 51 is located at the upper end of the connector 5 and is a rectangular groove; the second recess 52 is located at the lower end of the connector 5 and is a flattened oval groove. The connector 5 is inserted and fixed to the connecting shaft 11 through the first recess 51 and to the valve stem 21 through the second recess 52, thereby connecting and fixing the connecting shaft 11 and the valve stem 21, which facilitates disassembly.

[0035] Working principle: During installation, firstly, the bottom connecting shaft 11 of the actuator body 1 is inserted into the first recess 51 of the connector 5, and the valve stem 12 at the top of the valve 2 is inserted into the second recess 52 of the connector 5. Then, the upper clamping plate 33 and the lower clamping plate 34 surround the outside of the valve 2, and the upper clamping plate 33 and the lower clamping plate 34 are clamped and fixed by two clamps 35, thus achieving the fixed installation of the actuator body 1 and the valve 2. After the actuator body 1 is fixedly installed, by sending a remote control signal to the actuator body 1, the actuator body 1 drives the valve stem 21 of the valve 2 to rotate through the connecting shaft 11, thereby adjusting the flow rate of the valve 2.
