Description

Technical Field

[0001] The utility model relates to the technical field of regulating valves, in particular to an anti-scaling slide plate regulating valve. Background Art

[0002] Valves are devices used to regulate or switch the flow of gases, liquids, solids, or mixtures of these media in pipelines. They are widely used in industries such as petroleum, chemical engineering, electric power, metallurgy, and building materials. Traditional valves include ball valves, disc valves, eccentric rotary valves, gate valves, and slide valves. Slide valves, among others, have excellent application prospects due to their compact size, light weight, and long service life.

[0003] The existing technology has the following deficiencies: The prior art, "A Slide-Type Shut-Off Valve" with publication number CN202955259U, "comprises a valve body, a first valve seat, a second valve seat, a retaining ring, a slide, a valve cover, and a valve stem. The valve body has a transverse through-channel, and has an upper slide-accommodating cavity and a lower slide-accommodating cavity at corresponding positions above and below the transverse through-channel. The upper end of the upper slide-accommodating cavity is open. Through holes for the slide to pass through are provided between the transverse through-channel of the valve body and the upper and lower slide-accommodating cavities. The slide is inserted from the slide-accommodating cavity on the valve body into the transverse through-channel of the valve body."

[0004] When the above-mentioned device is in use, the flow passages on the first valve seat and the second valve seat can be opened or closed by pulling up or pressing down the valve stem; when the valve stem is pulled up, the slide moves upward and enters the slide accommodating chamber until the guide hole of the slide portion is connected with the guide passages on the first valve seat and the second valve seat, thereby opening the shut-off valve; when the valve stem is pressed down, the slide moves upward and enters the slide accommodating chamber until the slide separates the guide passages on the first valve seat and the second valve seat, thereby closing the shut-off valve. However, when the valve body is half-open, impurities in the fluid can easily enter the interior of the valve body. After long-term use, impurities in the medium can easily accumulate in the cavity to form scaling. Utility Model Content

It is characterized in that a first slide 5 and a second slide 6 are provided inside the through hole 4, and a connecting component is provided on the top of the first slide 5 and the second slide 6 respectively.

[0024] A forward and reverse motor 9 is provided at the top of the right valve body 1 near the fixed plate 3 , and rubber rings 18 are provided between the right valve body 1 and the left valve body 2 and the fixed plate 3 , respectively.

[0025] In this embodiment, the connecting plates 15 are fixedly mounted at the four corners of the fixing plate 3 corresponding to the ends of the right valve body 1 and the left valve body 2 that are close to each other. Threaded holes are respectively opened on both sides of the connecting plate 15 and the fixing plate 3. The internal threads of the threaded holes are threaded to install fixing bolts 16.

[0026] Furthermore, both sides of the rubber ring 18 are elliptical in shape, and grooves 17 adapted to the rubber ring 18 are respectively provided on both sides of the fixing plate 3 and on one end of the right valve body 1 and the left valve body 2 close to the fixing plate 3. When the right valve body 1 and the left valve body 2 are installed, the rubber ring 18 is placed between the right valve body 1 and the left valve body 2 and the fixing plate 3 to prevent the liquid or gas medium from overflowing during circulation, thereby ensuring the airtightness between the right valve body 1 and the left valve body 2 and the fixing plate 3;

[0027] Furthermore, the first slide plate 5 and the second slide plate 6 are symmetrically arranged and slidably installed inside the through hole 4. The left valve body 2 on the side opposite to the first slide plate 5 and the second slide plate 6 respectively extends to the outside of the fixed plate 3 and is slidably connected to the fixed plate 3. A positioning groove 7 is provided on the side of the first slide plate 5 close to the second slide plate 6. A positioning strip 8 is fixedly installed on the side of the second slide plate 6 close to the first slide plate 5 corresponding to the position of the positioning groove 7. Scraper rings 11 are fixedly installed on the inner wall of the through hole 4 corresponding to both sides of the first slide plate 5 and the second slide plate 6. The scraper ring 11 is conical.

[0028] Furthermore, the connecting assembly includes a first slide bar 12 and a second slide bar 13, both of which are inverted L-shaped arrangements. The first slide bar 12 is fixedly mounted on the top of the first slide plate 5, and the second slide bar 13 is fixedly mounted on the top of the second slide plate 6. The first slide bar 12 and the second slide bar 13 are staggered and arranged in opposite directions. The ends of the first slide bar 12 and the second slide bar 13 that are away from each other extend to the outside of the fixed plate 3 and are slidably connected to the fixed plate 3. A sliding groove 14 is provided inside the fixed plate 3 at positions corresponding to the first slide bar 12 and the second slide bar 13.

[0029] Furthermore, a gear shaft 10 is fixedly installed at the output end of the forward and reverse motor 9. The end of the gear shaft 10 away from the forward and reverse motor 9 passes through the fixed plate 3 and extends to the outside of the fixed plate 3, and is rotatably connected to the fixed plate 3. The gear shaft 10 is located between the first slide bar 12 and the second slide bar 13, and is meshed with the first slide bar 12 and the second slide bar 13. By starting the forward and reverse motor 9, the gear shaft 10 is driven to rotate, and the first slide bar 5 and the second slide bar 6 are driven to move in opposite directions through the meshing connection of the gear shaft 10 with the first slide bar 12 and the second slide bar 13, so that the flow channel is opened and the flow rate is adjusted. When the first slide bar 5 and the second slide bar 6 move to both sides, the scraper ring 11 cleans the impurities on the surface of the first slide bar 5 and the second slide bar 6, and flushes the impurities out through the fluid to prevent the impurities in the fluid from forming scale and causing blockage.

Then, by starting the forward and reverse motor 9, the gear shaft 10 is driven to rotate, and the gear shaft 10 is engaged with the first slide bar 12 and the second slide bar 13 to drive the first slide 5 and the second slide 6 to move in opposite directions, so that the flow channel is opened and the flow rate is adjusted. When the first slide 5 and the second slide 6 move to both sides, the scraper ring 11 cleans the impurities on the surface of the first slide 5 and the second slide 6 to prevent the impurities in the fluid from forming scale and causing blockage. When closing, the forward and reverse motor 9 is reversed, so that the first slide 5 and the second slide 6 are fitted together, and the positioning bar 8 is located inside the positioning groove 7, thereby increasing the airtightness between the first slide 5 and the second slide 6.
