Description

Technical Field

[0001] The utility model mainly relates to the field of electric control valves, and particularly relates to an electric control valve convenient for maintenance. Background Technique

[0002] The electric control valve is an important actuator unit instrument in industrial automation process control. With the increasing automation level in the industrial field, it is being more and more applied in various industrial production fields. Compared with the traditional pneumatic control valve, it has obvious advantages: the electric control valve is energy-saving (only consumes electric energy when working), environmentally friendly (no carbon emission), and quick and convenient to install (no complex pneumatic pipelines and air pump workstations). The valve is divided into three types according to the power used by its equipped actuator and according to its functions and characteristics: linear characteristic, equal percentage characteristic and parabolic characteristic.

[0003] The inventor found the following defects during the operation of specific embodiments:

[0004] During the use of the electric control valve, when liquid or gas passes through the electric control valve, impurities will adhere to the inside of the electric control valve, which will affect the opening and closing of the electric control valve subsequently. It is necessary to regularly clean the inner wall of the electric control valve. However, during the cleaning process of the electric control valve, it is necessary to remove the electric control valve from the inside of the pipeline or take out the inner valve core to clean the electric control valve. This method is time-consuming and laborious, and it is necessary to manually cut off the pipeline.

[0005] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0030] Refer to the appendix Figures 1-4 As shown in the figure, a convenient-to-maintain electric control valve includes an electric control valve body 1. Temporary sealing structures are arranged on both sides of the electric control valve body 1. A connecting pipe 6 is arranged at the bottom of the electric control valve body 1. A fitting groove 7 is formed between the connecting pipe 6 and the electric control valve body 1. An internal cleaning structure is arranged directly below the connecting pipe 6. Connecting flanges 2 are arranged at both ends of the electric control valve body 1.

[0031] The internal cleaning structure includes a sealing bottom plate 8. The sealing bottom plate 8 is threadedly connected to the connecting pipe 6. A lifting pipe 12 is arranged in the middle of the top of the sealing bottom plate 8. A lifting disc 15 is arranged at the top of the lifting pipe 12. A sealing ring 16 is arranged at the top of the lifting disc 15. Cleaning nozzles 17 are arranged on the outer wall of the lifting disc 15. The sealing ring 16 is slidably connected to the fitting groove 7.

[0032] When it is necessary to maintain and clean the surface of the valve core inside the electric control valve body 1, the temporary sealing structures on both sides seal both ends of the electric control valve body 1. Then the sealing ring 16 moves upward, so that the sealing ring 16 disengages from the fitting groove 7, and the lifting disc 15 enters the inside of the electric control valve body 1. The water pump sends the cleaning liquid into the cleaning nozzles 17 through the lifting pipe 12 and the lifting disc 15 and sprays it out through the cleaning nozzles 17, thereby realizing the cleaning of the impurities attached to the inner wall and the surface of the valve core of the electric control valve body 1.

[0033] Furthermore, the temporary sealing structure includes a connecting groove 3. The connecting groove 3 is opened at both ends of the inner wall of the electric control valve body 1. An electric push rod 4 is arranged at the bottom of the connecting groove 3. A sealing baffle 5 is arranged at the output end of the electric push rod 4. The sealing baffle 5 is slidably connected to the connecting groove 3. When it is necessary to maintain the valve core inside the electric control valve body 1, the electric push rod 4 is started. The electric push rod 4 pushes the sealing baffle 5 to move upward. The sealing baffle 5 seals both ends of the electric control valve body 1, and the electric control valve body 1 does not need to be removed from the inside of the pipeline to seal the pipeline, avoiding gas or liquid from entering the inside of the electric control valve body 1.

[0034] Further, a liquid outlet 9 is provided on one side inside the sealing bottom plate 8, a bottom bracket 10 is provided at the bottom of the sealing bottom plate 8, an electric telescopic rod 11 is provided in the middle of the outer wall of the bottom bracket 10, the output end of the electric telescopic rod 11 is connected to a lifting pipe 12, a driven gear 13 is slidably connected to the outer wall of the lifting pipe 12, a liquid inlet 14 is opened on the outer wall of the lifting pipe 12, the number of the cleaning nozzles 17 is set to be multiple, and the multiple cleaning nozzles 17 are annularly arrayed on the outer wall of the lifting disc 15. When maintenance is required inside the electric control valve body 1, both ends of the electric control valve body 1 are sealed by the sealing baffles 5, and then the electric telescopic rod 11 is started. The electric telescopic rod 11 drives the lifting pipe 12 to move upward, and the lifting pipe 12 drives the sealing ring 16 to disengage from the fitting groove 7, so that the lifting disc 15 enters the inside of the electric control valve body 1. Then, the water pump sends the cleaning agent into the inside of the lifting pipe 12 through the liquid inlet 14 and makes the cleaning agent enter the inside of the cleaning nozzles 17. The cleaning nozzles 17 spray out the cleaning agent, and the cleaning agent cleans the inside of the electric control valve body 1. Moreover, there is a gap between the lifting disc 15 and the fitting groove 7, and the used cleaning agent enters the inside of the connecting pipe 6 through the gap and is discharged through the liquid outlet 9 inside the sealing bottom plate 8. Then, the sealing ring 16 moves downward to fit with the fitting groove 7 to seal the inside of the electric control valve body 1.

[0035] The above embodiments only represent a certain implementation manner of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
