Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to a self-cleaning flat plate slide valve which is easy to install. Background Art

[0002] A slab gate valve is a sliding valve with parallel gates as its closing element. The pressure exerted by the gate against the valve seat is controlled by the medium pressure acting on the floating gate or floating seat. In the case of a double-disc slab gate valve, a spreading mechanism between the two gates supplements this pressure. Slab gate valves can be categorized by actuation method as manual, pneumatic, and electric.

[0003] The existing application number 202120737905.2 is a low-load self-cleaning wedge-type slide valve, which includes a valve body, a flow channel, a valve stem and a bracket. The flow channel is arranged horizontally and passes through the interior of the valve body, and also includes a limit sealing valve plate and a valve disc. The limit sealing valve plate includes a first limit sealing valve plate and a second limit sealing valve plate. The first limit sealing valve plate and the second limit sealing valve plate are arranged in a wedge shape. The first limit sealing valve plate is connected to the valve body, and the second limit sealing valve plate is connected to the valve body. The valve disc is arranged between the first limit sealing valve plate and the second limit sealing valve plate. The edge of the valve disc is knife-shaped. The valve disc also includes a valve disc middle body. The upper end of the valve disc middle body is fixedly connected to the valve stem. A universal guide block and a spring are arranged inside the valve disc middle body. The spring is arranged horizontally on the universal guide block. The low-load self-cleaning wedge-type slide valve is used. The opening and closing force of the slide valve is small during operation, and it can be replaced online, which is convenient for installation and protection, while improving the self-cleaning ability of the slide valve.

[0004] During the use of the existing flat slide valve, since the valve plate is in direct contact with the circulating liquid, impurities in the liquid will remain on the surface of the valve plate and inside the opening of the valve plate over a long period of time. The long-term accumulation of impurities will cause the opening to be blocked.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a self-cleaning flat slide valve that is easy to install is proposed. Utility Model Content

The cleaning brush can be used to clean the valve plate opening area.

[0012] Furthermore, the rotating head is made of rubber, and the side of the rotating head near the center of the cleaning chamber is in contact with the valve plate. During the process of the valve plate rising and falling, the contact between the valve plate and the rotating head can drive the rotating disc and the cleaning brush to rotate, thereby ensuring the purpose of cleaning the opening area of ​​the valve plate.

[0013] Furthermore, the adjustment mechanism includes an adjustment screw, which is fixedly connected to the bottom center of the rotating rod and extends through the interior of the valve plate.

[0014] Furthermore, sealing gaskets are embedded at both ends of the upper and lower sides of the inner cavity near the center of the valve body, and mounting plates are fixed at both ends of the top of the inner cavity of the valve body. Scrapers are evenly distributed on one side of the mounting plate near the center of the inner cavity of the valve body. The scrapers can be used to clean the surface of the valve plate without openings.

[0015] Furthermore, the scraper blade is close to the center of the inner cavity of the valve body and is in contact with the surfaces of both sides of the valve plate, and the cleaning chamber is integrated with the valve body and the valve cover. The integrated structure can ensure the sealing of the valve itself and avoid liquid leakage.

[0016] The utility model provides a self-cleaning flat plate slide valve that is easy to install and has the following beneficial effects:

[0017] The utility model provides a cleaning brush and a scraper. When liquid circulation is required, the opening area of ​​the valve plate coincides with the circulation area of ​​the liquid. During the lifting and lowering adjustment of the valve plate, the surface of the valve plate contacts the surface of the scraper, and the scraper cleans the impurities attached to the surface of the valve plate. When the circulation of liquid is isolated through the valve plate, the opening area of ​​the valve plate descends. During the descending process, the contact position between the rotating head and the valve plate is changed, which drives the rotating disk and the cleaning brush to rotate. Through the cooperation of the rotating disk and the cleaning brush, the opening area of ​​the valve plate is cleaned to ensure the smoothness of the liquid circulation.

Figures 1-4As shown, it includes a base 1, a cleaning chamber 2 fixed to the top of the base 1, a valve body 3 fixed to the top of the cleaning chamber 2, a valve cover 4 fixed to the top of the valve body 3, a rotating rod 5 rotatably connected to the inside of the valve cover 4, a valve disc 6 fixed to the top of the rotating rod 5, pipe connectors 7 fixed to both ends of the valve body 3, and a valve plate 8 slidably connected to the inside of the valve body 3; a cleaning mechanism for cleaning the internal opening of the valve plate 8 is provided inside the cleaning chamber 2; an adjustment mechanism for adjusting the position of the valve plate 8 is provided at the bottom of the rotating rod 5. A connecting flange 9 is fixed to the side of the pipe connector 7 away from the center of the valve body 3, and a delivery pipe 10 is provided on the side of the connecting flange 9 away from the center of the valve body 3.

[0025] In this embodiment, the valve body 3 and the delivery pipe 10 are connected by the cooperation of the connecting flange 9 and the bolts. During use, the opening area in the valve plate 8 is cleaned by the cleaning brush 12 in the cleaning chamber 2 to avoid blockage of the opening area due to accumulation of impurities. The position of the valve plate 8 is adjusted by rotating the rotating rod 5 and the valve disc 6 to ensure the fluidity of the liquid and to block the flow of the liquid as needed.

[0026] In the first embodiment, since the port area is in contact with the liquid for a long time, impurities in the liquid are likely to accumulate. The specific operation is as follows:

[0027] like Figure 2 and Figure 3 As shown, the cleaning mechanism includes a rotating disk 11, which is rotatably connected to the inside of the two ends of the cleaning chamber 2. A cleaning brush 12 is fixed to the side of the rotating disk 11 near the center of the cleaning chamber 2, and rotating heads 13 are evenly distributed on the outside of the rotating disk 11 near the center of the cleaning chamber 2. The rotating heads 13 are set to a rubber material, and the side of the rotating head 13 near the center of the cleaning chamber 2 is in contact with the valve plate 8.

[0028] In this embodiment: when the liquid is isolated, the opening area in the valve plate 8 descends to the inside of the cleaning chamber 2. During the descending process, the surface of the valve plate 8 contacts one side of the rotating head 13. Since the rotating head 13 is set to a rubber material, the rotating disk 11 and the cleaning brush 12 are driven to rotate during the process of the valve plate 8 contacting the rotating head 13 and continuing to descend. The opening area of ​​the valve plate 8 is cleaned by the cleaning brush 12 to avoid the accumulation of impurities in the opening and ensure the smooth flow of the liquid.

[0029] In the previous embodiment, since the isolation area of ​​the valve plate 8 is in long-term contact with the liquid, impurities will adhere to the surface of the valve plate 8. The specific operation is as follows:

[0030] like Figure 2 and Figure 4As shown, the adjustment mechanism includes an adjustment screw 14, which is fixedly connected to the bottom center of the rotating rod 5. The adjustment screw 14 extends through the interior of the valve plate 8. The valve plate 8 forms a lifting structure with the inner cavity of the valve body 3 through the adjustment screw 14. Sealing gaskets 15 are embedded at both ends of the upper and lower sides of the inner cavity of the valve body 3 near the center. Mounting plates 16 are fixed at both ends of the top of the inner cavity of the valve body 3. Scrapers 17 are evenly distributed on the side of the mounting plate 16 near the center of the inner cavity of the valve body 3. The side of the scraper 17 near the center of the inner cavity of the valve body 3 is in contact with the surfaces of both sides of the valve plate 8, and the cleaning chamber 2 is integrally connected to the valve body 3 and the valve cover 4.

[0031] In this embodiment: the valve disc 6 drives the rotating rod 5 and the adjusting screw 14 to rotate, and the adjusting screw 14 drives the position of the valve plate 8 to rise and fall inside the valve body 3, thereby changing the flow state of the liquid. The sealing gasket 15 can prevent the liquid from leaking at the gap. When the valve plate 8 is adjusted to a state where liquid flows, the scraper 17 is used to clean the isolation area of ​​the valve plate 8 to prevent impurities from adhering to the surface of the valve plate 8.

[0032] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
