Description

Technical Field

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

[0002] A valve is a device used in fluid systems to control the direction, pressure, and flow rate of a fluid. It allows the medium within piping and equipment to flow or stop and controls its flow rate, providing functions such as guiding, stopping, throttling, check valves, diverting flow, or overflow pressure relief. Valves are classified according to their actuation method: manual, electric, hydraulic, pneumatic, electromagnetic, electromagnetic-hydraulic, and electro-hydraulic. Electric valves are the most widely used due to their relatively simple structure and lower cost. Currently, electric valves on the market typically use servo motors to directly drive the opening and closing parts to achieve this.

[0003] A torque protection mechanism for an electric valve actuator, disclosed in CN219866581U, includes: a valve structure comprising a valve body and a valve stem disposed within the valve body; a plurality of mounting feet are fixedly connected to the outer side wall of the valve body, and mounting holes extending through the front and rear are provided on the side wall of the mounting feet; and a vertical protective cover is fixedly connected to the upper end of the valve body.

[0004] A smart electric valve with publication number CN106090387A includes a valve and an electric actuator. The valve is equipped with an opening and closing element that can rotate to open or close the valve port. The electric actuator precisely drives the opening and closing element to rotate. The valve also includes a positioner installed on the side of the electric actuator. The positioner is equipped with a signal acquisition module, a signal conversion module, a data storage module, a display module, and a central control module. The signal acquisition module accurately detects the rotation angle of the opening and closing element and transmits the signal to the data storage module for storage. The signal conversion module converts the physical signal into an electrical signal and transmits it to the display module.

[0005] Current technologies for displaying the rotation angle of the valve core are lacking in terms of valve stem protection and intuitive angle observation. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] See Figures 1-5 As shown, this utility model provides a convenient electric valve actuator, including an electric valve body 1 and a housing 2 made of reinforced polyamide plastic. The valve stem output shaft end of the electric valve body 1 is securely installed with an angle display umbrella structure 4 by means of interference fit or key connection, so that the angle display umbrella structure 4 can rotate synchronously with the valve stem output shaft, accurately feeding back the opening or closing angle of the electric valve.

[0030] The housing 2 is connected to the electric valve body 1 by a flange. A flange is provided on the edge of the electric valve body 1, and a matching flange structure is also provided at the corresponding position of the housing 2. A tight connection is achieved by passing bolts through the bolt holes of both and tightening them, so that the angle display umbrella structure 4 is completely covered inside. The housing 2 is provided with a viewing window 3 for observing the rotation of the angle display umbrella structure 4.

[0031] The housing 2 has an opening groove 201, and a recessed groove 202 is provided at the port of the opening groove 201 facing the outside of the housing 2. The viewing window 3 is disposed in the recessed groove 202. An annular sealing groove 6 is provided on the outer wall of the housing 2 between the opening groove 201 and the recessed groove 202. A sealing gasket 5 is provided in the annular sealing groove 6 to achieve a sealing contact with the viewing window 3. After the sealing gasket 5 is embedded, it can fit tightly against the edge of the viewing window 3 during installation, forming a reliable seal.

[0032] This utility model provides a first embodiment of an angle display umbrella disc structure 4: The angle display umbrella disc structure 4 includes a turntable 401 disposed at the valve stem output shaft end. A collar 402 is sleeved on the outer side of the turntable 401, and an umbrella disc 404 is disposed on the outer side of the collar 402, which serves to expand the display of the rotation angle and facilitate observation of the rotation edge of the umbrella disc 404 through the viewing window 3. A locking block 403 is provided on the inner side of the collar 402, and a locking groove is provided on the outer wall of the turntable 401 for cooperating with the locking block 403, which is used to limit the circumferential movement of the collar 402 relative to the turntable 401 and ensure that the two rotate in tandem. A first display area 405 and a third display area 407, which are distinguished by different colors such as red, yellow, and green, are respectively provided on the upper surface of the turntable 401 along its circumference. A second display area 406 is provided between the first display area 405 and the third display area 407 to separate them. The upper surface of the umbrella disc 404 has several evenly distributed angle markers 408 along its circumference. One of the angle markers 408 is located in the second display area 406, which facilitates the operator to quickly read the key angle position information of the electric valve. The umbrella disc 404 is equipped with a ring-shaped illumination lamp 409 for easy observation in low-light conditions.

[0033] This utility model provides a second embodiment of the angle display umbrella disc structure 4: The angle display umbrella disc structure 4 includes a turntable 401 disposed at the valve stem output shaft end, a collar 402 sleeved on the outer side of the turntable 401, and an umbrella disc 404 disposed on the outer side of the collar 402. A locking block 403 is provided on the inner side of the collar 402, and a locking groove for cooperating with the locking block 403 is provided on the outer wall of the turntable 401. Angle scale markings 410 are provided on the upper surface of the turntable 401 along its circumference, and partition points 411 are provided on the turntable 401. A ring-shaped illumination lamp 409 is provided on the umbrella disc 404.

[0034] Working principle:

[0035] In operation, when the electric valve is working, the valve stem output shaft rotates, causing the angle display umbrella structure securely connected to it to rotate synchronously. The turntable 401 and collar 402 in the umbrella structure cooperate via a locking block 403 and a locking groove to ensure coordinated rotation. The angle scale markings 410 on the turntable, the color-coded display areas, and the evenly distributed angle marking points 408 on the umbrella structure all rotate with the valve stem. The operator can accurately determine the opening or closing angle of the electric valve by observing these markings through the viewing window 3 on the housing 2. In low light conditions, the ring light 409 on the umbrella structure illuminates the markings for easy observation.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
