Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an electric single-seat regulating valve. Background Technology

[0002] The electric single-seat control valve is a pressure-balanced control valve. It receives a DC current signal from the regulating instrument, changes the flow rate of the regulated medium, and maintains the controlled process parameters at a given value. It is widely used in the production automation control of industries such as power, metallurgy, chemical, petroleum, light textile, pharmaceutical, and papermaking. Currently, in order to improve the service life of the electric single-seat control valve (valve body) and reduce the frequency of valve body maintenance, a filter device is usually installed at the inlet of the valve body.

[0003] As existing technology, Chinese patent CN213871122U proposes an electric single-seat regulating valve with anti-clogging function. However, this solution still has the following problems when in use: the bevel gear is easily worn and damaged by the influence of humid and dusty environments. The blockage relies on the spring rebound seal. After long-term use, the spring elasticity may weaken, leading to seal failure. There is still room for improvement. Summary of the Invention

[0004] The purpose of this utility model is to provide an electric single-seat regulating valve to solve the problems mentioned in the background art.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: an electric single-seat regulating valve, including a valve body, with an inlet pipe and an outlet pipe respectively provided on both sides of the valve body, an actuator installed on the top of the valve body, a baffle provided on the inner wall of the inlet pipe, the baffle having a plurality of filter holes and a rotating rod vertically rotatably connected to its center, a first support rod vertically connected to the front end of the rotating rod and a second support rod vertically connected to its rear side, a scraper provided on the rear side of the first support rod, and corresponding annular groove one and annular groove two respectively provided on the inner and outer walls of the inlet pipe, magnetic blocks one at both ends of the second support rod and slidably connected to the inner wall of annular groove one, a rotating ring rotatably connected in annular groove two, and a magnetic block two corresponding to the position of magnetic block one on the rotating ring.

[0006] Using the above technical solution, during operation, rotating the rotating ring drives the second magnetic block to rotate. The rotation of the second magnetic block drives the first magnetic block to rotate through magnetic force. The first magnetic block drives the second bracket to rotate. The rotation of the second bracket drives the first bracket to rotate through the rotating rod, thereby driving the scraper to rotate. The scraper removes the impurities accumulated on the surface of the baffle. The use of magnetic transmission eliminates the need to set up a transmission structure in a humid and dusty environment, reduces the probability of wear and tear failures, and extends the service life.

[0007] Furthermore, a support and a motor are provided on the upper side wall of the inflow pipe, and toothed blocks are provided on the outer wall of the rotating ring along the circumference. A gear is mounted on the support and meshes with the toothed blocks, and the output shaft of the motor is connected to the gear. During operation, the motor is turned on, and the output shaft of the motor drives the gear to rotate. The rotation of the gear drives the rotating ring to rotate through the toothed blocks.

[0008] Furthermore, the lower sidewall of the inflow pipe is provided with an extension tube. The inflow pipe has a through hole on the lower side of the scraper that communicates with the extension tube. A rotating shaft is vertically installed inside the extension tube, and a sealing plate is fixed on the rotating shaft. The shape of the sealing plate matches the inner wall shape of the extension tube. One end of the rotating shaft extends through the sidewall of the extension tube, and the extension tube has external threads. The system also includes a bottle body, the opening of which has internal threads that match the extension tube. Impurities brushed off by the scraper fall into the bottle body through the through hole and are collected. Before the bottle body is removed, the sealing plate is rotated by the rotating shaft to prevent impurities from flowing down. The structure is simple and operable, and it is less prone to sealing failure due to aging. Then, the bottle body is rotated and removed from the extension tube.

[0009] Furthermore, the rotating shaft is vertically provided with an extension rod, which has an external thread and is threadedly fitted with a locking sleeve. The side wall of the inlet pipe is provided with a protrusion, which has an external thread that matches the locking sleeve. During operation, rotating the locking sleeve connects it to the threaded protrusion, thereby locking the rotating shaft circumferentially, keeping the sealing plate vertical, allowing impurities to pass through and flow into the bottle.

[0010] Furthermore, the inner walls on both sides of the annular groove are provided with sliding grooves, and the two sides of the rotating ring are provided with sliders that are slidably connected to the sliding grooves.

[0011] Furthermore, the first magnetic block is embedded inside the second bracket, and the first magnetic block is embedded inside the rotating ring.

[0012] Furthermore, the inner walls of both the first and second annular grooves are provided with arc-shaped chamfers.

[0013] Furthermore, the scraper is made of elastic rubber, and the elasticity of the rubber can enhance its ability to clean stubborn impurities.

[0014] The beneficial effects of this utility model are: the use of magnetic transmission eliminates the need to set up a transmission structure in a humid and dusty environment, reduces the probability of wear and tear failures, and extends the service life. The rotating sealing plate with a rotating shaft blocks impurities from flowing down. The structure is simple and easy to operate, and it is not prone to sealing failure due to aging.

The bracket 7 is provided with a gear 72 that meshes with the toothed block 61. The output shaft of the motor 71 is connected to the gear 72.

[0019] The principle of this utility model is as follows: When operating, the motor 71 is turned on, and the output shaft of the motor 71 drives the gear 72 to rotate. The rotation of the gear 72 drives the rotating ring 6 to rotate through the tooth block 61. The rotation of the rotating ring 6 drives the second magnetic block 52 to rotate.

The scraper scrapes away the impurities accumulated on the surface of the baffle 2. The use of magnetic transmission eliminates the need to set up a transmission structure in a humid and dusty environment, reduces the probability of wear and tear failure, and extends the service life. Example 2:

[0020] This embodiment further includes an extension tube 114 on the lower side wall of the inflow pipe 11.

The principle of this utility model is as follows: During operation, the rotating locking sleeve 83 is threadedly connected to the protrusion 115, thereby locking the rotating shaft 8 circumferentially, keeping the sealing plate 81 in a vertical state, allowing impurities to pass through and flow into the bottle. Impurities brushed off by the scraper fall into the bottle body for collection after passing through the through hole 113. Before the bottle body is removed, the sealing plate 81 is rotated by the rotating shaft 8 to block the impurities from flowing down. The structure is simple and operable, and it is not easy for the seal to fail due to aging. Then the bottle body 9 is rotated and removed from the extension tube.
