Technical Field

[0001] The utility model belongs to the technical field of valve actuators, and more specifically, relates to an encodable motor for a valve actuator. Background Art

[0002] The valve actuator encoder motor is a device that integrates a motor and an encoder to control and drive the opening and closing of the valve. It is usually used in automation systems to accurately control the position and operating status of the valve by receiving external control signals.

[0003] Some current valve actuators with coded motors are usually directly installed on the valve actuator as a whole. When installed outdoors, there is a lack of protection measures. External rainwater can easily enter the motor directly, causing damage to the motor. When the valve actuator continues to run, the motor is prone to generate a large amount of heat accumulation, affecting its service life.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a valve actuator encodable motor is provided to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the present invention provides a valve actuator with an encodeable motor, which is achieved by the following specific technical means:

[0022] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] Example:

[0024] As attached Figure 1 To the attached Figure 4 As shown:

[0025] The utility model provides an encodable motor for a valve actuator, comprising a mounting plate 1, an outer shell 2 being mounted at the edge of one side of the mounting plate 1, four openings 3 being equidistantly provided on the circumference of the outer shell 2, a sealing gasket 4 being mounted on the inner side of the outer shell 2, a plurality of cooling fans 5 being mounted on one side of the outer shell 2, an annular mounting groove 6 being provided on one side of the mounting plate 1, an annular mounting seat 7 being rotatably mounted in the annular mounting groove 6, four sealing plates 8 being equidistantly mounted on one side of the annular mounting seat 7, a toggle rod 9 being mounted on the other side of the annular mounting seat 7, limit grooves 10 being provided on the annular mounting seat 7 at positions on both sides of the toggle rod 9, a motor body 11 being mounted on one side of the mounting plate 1, and a limit assembly being mounted on the other side of the mounting plate 1.

[0026] The size of the sealing plate 8 matches that of the opening 3 , so that the sealing plate 8 can completely block the opening 3 after rotation, and cooperate with the sealing gasket 4 to prevent rainwater from entering the outer shell 2 and affecting the operation of the motor body 11 .

[0027] The outer side of the sealing plate 8 is in close contact with the inner side of the outer shell 2 .

[0028] The diameter of the annular mounting seat 7 is smaller than the diameter of the outer shell 2 , so that the four sealing plates 8 can be located inside the outer shell 2 .

[0029] The diameter of the motor body 11 is smaller than the diameter of the annular mounting seat 7 , so that the motor body 11 can be located inside the four sealing plates 8 .

[0030] Among them, the limiting assembly includes an arc-shaped slide 12 and a number of tension springs 13. The arc-shaped slide 12 runs through the top of one side of the mounting plate 1, and the arc-shaped slide 12 is connected to the annular mounting groove 6. A number of tension springs 13 are installed on one side of the mounting plate 1 at a position below the arc-shaped slide 12. A mounting plate 14 is installed on one side of the number of tension springs 13. The mounting plate 14 is installed with a limiting rod 15 at the top of the side close to the arc-shaped slide 12. The toggle rod 9 passes through the arc-shaped slide 12 and extends to the outside of the arc-shaped slide 12. When the motor body 11 does not need to be shielded and protected, the four sealing plates 8 and the four openings 3 are in a staggered state. At this time, the limit The positioning rod 15 is located inside one of a pair of limiting grooves 10. When the outside weather is rainy or the motor body 11 needs to be protected, the staff can pull the mounting plate 14 to disengage the limiting rod 15 from the limiting groove 10, and then toggle the toggle rod 9 to move the toggle rod 9 from one side of the arc-shaped slide groove 12 to the other side and drive the annular mounting seat 7 and the four sealing plates 8 to rotate. At this time, the positions of the four sealing plates 8 are respectively parallel to the four openings 3 and cover the four openings 3. Finally, the staff releases the mounting plate 14, and under the action of the rebound of the tension spring 13, the limiting rod 15 enters the other limiting groove 10 to fix the annular mounting seat 7.

[0031] The limiting rod 15 passes through the arcuate slide groove 12 and is slidably connected to the arcuate slide groove 12, so as to facilitate fixing the annular mounting seat 7.

[0032] The size of the limiting rod 15 matches the size of the pair of limiting grooves 10 , making it easier to fix the annular mounting seat 7 .

[0033] The working principle of this embodiment: When the valve actuator encodeable motor is in use, the cooling fan 5 is turned on to assist in dissipating heat to the motor body 11. At this time, the limit rod 15 is located inside one of the pair of limit grooves 10, and the four sealing plates 8 are in an interlaced state with the four openings 3, so that the opening 3 is in an open state, thereby improving the heat dissipation efficiency. When the outside weather is rainy or the motor body 11 needs to be protected, the staff can pull the mounting plate 14 to disengage the limit rod 15 from the limit groove 10, and then toggle the toggle rod 9 to move the toggle rod 9 from one side of the arc slide groove 12 to the other side and drive the annular mounting seat 7 and the four sealing plates 8 to rotate. At this time, the positions of the four sealing plates 8 are respectively parallel to the four openings 3 and block the four openings 3 to prevent rainwater and other objects from entering the outer shell 2 and causing damage to the motor body 11. Finally, the staff loosens the mounting plate 14, and under the action of the rebound of the tension spring 13, the limit rod 15 enters another limit groove 10 to fix the annular mounting seat 7.
