Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water valves, and more specifically to a gate valve for sewage treatment. Background Art
[0002] Existing gate valves typically consist of a gate, a screw, a hoist, and a gate frame. The gate frame features a chute inside which the gate is mounted. The chute is fitted with a sealing strip that mates with the side of the gate. The gate frame supports the gate and is anchored to the secondary concrete of the gate pier and base plate by anchor bolts. This ensures that all water pressure applied to the gate is safely transferred to the gate chamber. The gate is opened and closed by the screw, which pulls upward and downward.
[0003] However, the existing gate valve has the following disadvantages: when the medium flows, debris is easily deposited in the groove on the bottom side of the gate frame, which can easily cause the gate to not be fully in place when closed, resulting in an inability to completely isolate the medium. If the gate is large and installed in a deep position, the groove is difficult to clean, especially cleaning below the liquid surface is more difficult to complete. A large gate means a large flow area. If this type of large gate valve leaks, the impact on the system is very serious. Utility Model Content
[0004] In view of the above problems, the purpose of this utility model is to provide a gate valve for sewage treatment, which can prevent medium sediment from settling in the groove at the bottom of the gate frame, and clean up the debris in the groove in time to ensure that the bottom of the valve disc is effectively sealed.
[0005] The utility model provides a gate valve for sewage treatment, comprising a gate frame and a gate, wherein an elastic anti-fouling baffle is provided in the bottom groove of the bottom frame of the gate frame, and a baffle spraying component is provided on the bottom frame, wherein:
[0006] The elastic anti-fouling baffle includes spring dampers uniformly arranged along the length direction at the bottom of the bottom groove, and the upper ends of all the spring dampers are connected to the anti-fouling baffle. When the spring dampers are in a free state, the anti-fouling baffle is flush with the top surface of the bottom groove. When the spring dampers are in a depressed state, the anti-fouling baffle enters the interior of the bottom groove, and the area of the anti-fouling baffle is adapted to the internal cross-section of the bottom groove.
[0007] The baffle spraying component includes nozzles uniformly arranged along the length direction of the bottom frame, the nozzles facing the anti-fouling baffle, and all the nozzles are connected to a high-pressure water pump.
[0008] The bottom frame is a plane, the bottom groove is a steel plate groove, the bottom groove is installed on the bottom frame, and has the same length as the bottom frame, and the inner width of the bottom groove is adapted to the thickness of the gate plate.
[0009] The inner sides of the two side walls of the bottom groove are covered with sealing strips.
[0010] The thickness of the sealing strip is not greater than 3 mm.
[0011] The length of the anti-fouling baffle is equal to the length of the bottom groove, and the width is equal to the distance between the two sealing strips. The edge of the anti-fouling baffle is set to be smooth.
[0012] The number of the spring dampers is at least 3.
[0013] The height at which the spring damper is pressed to the bottom is less than half the depth of the bottom groove.

[0015] A reinforcing rod is provided between the support rod and the upper side surface of the bottom frame.
[0016] The nozzle is a high-pressure water nozzle.
[0017] As can be seen from the above description, the gate valve for sewage treatment provided by the present utility model includes a resilient anti-fouling baffle plate disposed in a bottom groove that can be pressed downward and rebounded, thereby blocking debris from entering the bottom groove. The baffle plate spray cleaning component can promptly flush debris from the resilient anti-fouling baffle plate, preventing debris from entering the groove when the gate plate is closed, thereby preventing the seal from being loosened. The gate valve of the present utility model has improved sealing performance, reduces the difficulty of cleaning and maintenance, and improves work efficiency and safety.

[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0031] Figure 2 This is a structural diagram of a gate valve for sewage treatment according to an embodiment of the present utility model; Figure 3 This is a schematic structural diagram of an elastic anti-fouling baffle according to an embodiment of the present utility model;
[0032] like Figure 2 and Figure 3 As shown, the gate valve for sewage treatment proposed in this embodiment can be used to strictly shut off the water channel of the sewage treatment plant, and can also be used to shut off other water flows.
[0033] This gate valve for sewage treatment is different from the existing square gate valve (such as Figure 1 On the basis of the embodiment shown in FIG, the bottom groove at the bottom of the gate frame 1 is improved so that the bottom groove will not accumulate debris. After the gate plate 2 is closed, the lower end enters the bottom groove without clamping debris, thereby enhancing the sealing performance.
[0034] The present sewage treatment gate valve is provided with an elastic anti-fouling baffle 4 in the bottom groove 3 of the bottom frame, and a baffle spraying component 5 is provided at the lower part of the gate frame 1. The elastic anti-fouling baffle 4 is elastic. When the gate 2 is closed, the lower end of the gate 2 enters the bottom groove 3. The elastic anti-fouling baffle 4 is pressed down into the bottom groove 3 by pressure. The lower end of the gate 2 is in the bottom groove 3, and the side of the gate 2 is in the side slide groove of the gate frame 1. The gate 2 is tightly closed. When the gate 2 is opened, the elastic anti-fouling baffle 4 rebounds to the upper end surface of the bottom groove 3 without pressure, which is equivalent to covering the bottom groove 3, and debris does not enter the bottom groove 3. The baffle spraying component 5 can be used to flush debris above the elastic anti-fouling baffle 4 before the gate 2 is closed. The baffle spraying component 5 should spray water on the water inlet side of the gate 2. The medium flow will not affect the flushing effect of the water spraying. The baffle spraying component 5 does not hinder the closing and opening of the gate 2.
[0035] Specifically, the elastic anti-fouling baffle 4 may include spring dampers 41 uniformly arranged along the length direction at the bottom of the bottom groove 3, and an anti-fouling baffle 42 is commonly connected to the upper ends of all spring dampers 41. When the spring dampers 41 are in a free state, the anti-fouling baffle 42 is flush with the top surface of the bottom groove 3. When the spring dampers 41 are in a downward pressed state, the anti-fouling baffle 42 enters the interior of the bottom groove 3, and the area of the anti-fouling baffle 42 is adapted to the internal cross-section of the bottom groove 3.
[0036] The lower ends of the spring dampers 41 are connected to the bottom of the bottom groove 3, and the upper ends are fixed to the anti-fouling baffle 42. The spring dampers 41 support the anti-fouling baffle 42, allowing it to follow the downward pressure of the gate plate 2 and descend into the bottom groove 3, exposing the groove body and not hindering the gate plate 2 from entering the bottom groove 3, thus positioning the bottom of the gate plate 2. As the gate plate 2 rises, the spring dampers 41 return to their original positions and rise, lifting the anti-fouling baffle 42 to the upper end of the bottom groove 3, covering the bottom groove 3 like a lid to prevent debris from entering the groove body.
[0037] In order to cover the bottom groove 3 well and move up and down smoothly in the bottom groove 3, the width of the anti-fouling baffle 42 should be equal to or slightly smaller than the internal cross-sectional width of the bottom groove 3, and the length of the anti-fouling baffle 42 should be equal to the length of the bottom groove 3.
[0038] The anti-fouling baffle 42 with automatic rising and falling functions is adopted. When the gate valve is opened, the water flows normally and the bottom groove 3 is covered. When the gate valve is closed, the groove body of the bottom groove 3 is exposed, tightly socketing the gate plate 2, which can automatically prevent pollution.
[0039] The spring damper 41 should be waterproof and rustproof, and the arrangement of the spring damper 41 should ensure that its stress can stably support the antifouling baffle 42. The specification of the spring damper 41 is selected according to specific circumstances.
[0040] In this embodiment, the number of the spring dampers 41 is at least three, and the height of the spring dampers 41 pressed to the bottom is less than half the depth of the bottom groove 3, ensuring that the gate plate 2 has an effective length when inserted into the bottom groove 3.
[0041] In a specific embodiment of the present invention, the bottom frame is flat, and the bottom groove 3 can be a steel plate groove. The bottom groove 3 of the steel plate groove is installed on the bottom frame and is equal to the length of the bottom frame. The inner width of the bottom groove 3 is adapted to the thickness of the gate plate 2. The width of the bottom groove 3 is smaller than the width of the bottom frame and is generally located in the middle of the bottom frame.
[0042] The bottom groove 3 can be made of channel steel or steel plate, and the bottom groove 3 can be welded or installed on the bottom frame with stainless steel bolts. The installable bottom groove 3 is convenient for installing the elastic anti-fouling baffle 4. In order to tightly plug with the gate plate 2, the length of the bottom groove 3 is equal to the length of the bottom frame. The lower end of the gate plate 2 is completely inserted into the bottom groove 3. After the gate plate 2 is inserted into the bottom groove 3, the side wall is in contact with the gate plate 2.
[0043] In one embodiment of the present invention, to further enhance the tightness of the insertion, the inner sides of both sidewalls of the bottom groove 3 are covered with a sealing strip 6. The sealing strip 6 provides a tight seal between the gate plate 2 and the sidewalls of the bottom groove 3, enhancing waterproofing. The thickness of the sealing strip 6 should not be too large, and may be no greater than 3 mm.
[0044] The anti-fouling baffle 42 should move up and down smoothly between the two sealing strips 6 without scratching the sealing strips 6. The width of the anti-fouling baffle 42 can be equal to the distance between the two sealing strips 6, and the edge of the anti-fouling baffle 42 is set to be smooth. The anti-fouling baffle 42 is located between the two sealing strips 6, and the smooth edge of the anti-fouling baffle 42 contacts the sealing strips 6, which ensures that the anti-fouling baffle 42 does not damage the sealing strips 6 and ensures that debris such as mud and sand are strictly blocked.
[0045] When the gate 2 is open on a daily basis, debris will also gather on the upper part of the elastic anti-fouling baffle 4. In order to automatically remove these debris, the baffle spraying component 5 may include nozzles 51 evenly arranged along the length direction of the bottom frame. The nozzles 51 are all facing the anti-fouling baffle 42, and all nozzles 51 are connected to the high-pressure water pump 52.
[0046] Before the gate 2 is about to close, the high-pressure water pump 52 is opened to spray water onto the elastic anti-fouling baffle 4 to clean the foreign matter on the elastic anti-fouling baffle 4. The upper part of the elastic anti-fouling baffle 4 can also be frequently cleaned when the gate 2 is open to prevent the dirt from agglomerating.
[0047] In a specific embodiment of the present invention, the nozzle 51 is a high-pressure water nozzle, and the water sprayed by the high-pressure water nozzle has a stronger cleaning force.
[0048] In a specific embodiment of the present invention, in order to stably set the nozzle 51, support rods 53 are evenly arranged on the side of the bottom frame parallel to the gate plate 2. This side is located on the water inlet side of the gate plate 2. The upper ends of all support rods 53 are commonly connected to a horizontal cross pipe 54. Nozzle connection ports are evenly arranged on the cross pipe 54. After the nozzle 51 is connected to the nozzle connection port, the nozzle 51 faces the anti-fouling baffle 42. One end of the cross pipe 54 is closed, and the other end is connected to a vertical pipe 55. The vertical pipe 55 is arranged upward along the side of the side frame of the gate frame 1 and parallel to the gate plate 2, and is connected to the high-pressure water pump 52. The high-pressure water pump 52 is placed outside the water channel.
[0049] All the nozzles 51 are located on the water inlet side of the gate plate 2 , and the sprayed water follows the flow of the medium and can be effectively sprayed onto the anti-fouling baffle 42 .
[0050] The plurality of support rods 53 arranged on the bottom frame jointly stably support the transverse tube 54. In order to support more firmly, a reinforcing rod 56 can also be provided between the support rod 53 and the bottom frame upper side.
[0051] When high-pressure water pump 52 is turned on, high-pressure water is delivered along vertical pipe 55 and horizontal pipe 54 to each nozzle 51. Each nozzle 51 simultaneously sprays water toward elastic anti-fouling baffle 4 covering the top of the bottom groove, effectively removing dirt. Nozzles 51, support rods 53, horizontal pipe 54, and vertical pipe 55 are all located on the side of gate frame 1 so as not to interfere with the closing and opening of gate plate 2.
[0052] The above description of the gate valve for sewage treatment according to the present invention is based on examples and is based on the accompanying drawings. However, those skilled in the art will appreciate that various improvements can be made to the gate valve for sewage treatment proposed in the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the contents of the appended claims.
