Description

Technical Field

[0001] This utility model relates to the field of drainage valve technology, and in particular to a corrosion-resistant drainage valve. Background Technology

[0002] Currently, drainage valves on the market are insufficient in terms of corrosion resistance. Many valves are made of ordinary materials, which are easily corroded when in contact with sewage containing corrosive components such as acids and alkalis for a long time. This leads to valve seal failure, structural damage, and consequently affects the normal operation of drainage equipment, increasing maintenance costs and replacement frequency. In addition, drainage valves mostly rely on manual adjustment for flow control, which is not only inconvenient to operate but also difficult to achieve precise control, failing to meet the needs of modern drainage equipment for refined flow management. Furthermore, in terms of impurity filtration, most drainage valves are only equipped with a single filter screen, with limited filtration effect, unable to effectively intercept impurities of different particle sizes. These unfiltered impurities not only clog the pipes but also wear down the inner wall of the pipes during flow, accelerating pipe corrosion and damage, and shortening the service life of drainage equipment. Therefore, it is necessary to design a corrosion-resistant drainage valve to solve the above problems. Utility Model Content

[0003] The main objective of this invention is to provide a corrosion-resistant drainage valve that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

A main body device is fixedly connected to the right end of the side plate. Six connecting strips are fixedly connected to the left wall of the water pipe. A first filter disc is snap-fitted onto the left wall of the water pipe. A through rod is fixedly connected to the middle of the right end of the first filter disc. A second filter disc is fixedly connected to the other end of the through rod. A first filter screen and a second filter screen are fixedly connected to the right ends of the first and second filter discs, respectively.

An installation groove is opened on the front of the outer surface of the adjusting valve plate. The adjusting valve plate is fixedly connected to the rear end of the connecting rod. The electric push rod is fixedly connected to the right end of the side plate.

[0007] Preferably, the position and size of the connecting strip are adapted to the position and size of the connecting groove, and the connecting strip is distributed in a ring at equal intervals on the left side of the inner wall of the water pipe with the water pipe as the center.

[0008] Preferably, the structure of the first filter disc is the same as that of the second filter disc and they are symmetrically distributed from left to right, and the mesh diameter of the insert rod is larger than that of the second filter screen.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A corrosion-resistant drainage valve includes a water pipe 2, a cavity 7 inside the water pipe 2, flanges 1 at both ends of the water pipe 2, a groove 4 on the front of the outer surface of the water pipe 2, a side plate 3 fixedly connected to the front of the outer surface of the water pipe 2, a main body device 6 fixedly connected to the right end of the side plate 3, six connecting strips 9 fixedly connected to the left wall of the water pipe 2, a first filter disc 8 snapped onto the left wall of the water pipe 2, a through rod 12 fixedly connected to the middle of the right end of the first filter disc 8, a second filter disc 13 fixedly connected to the other end of the through rod 12, a first filter screen 11 and a second filter screen 14 fixedly connected to the right end of the first filter disc 8 and the right end of the second filter disc 13, respectively, six connecting grooves 10 on the outer surface of the first filter disc 8 and the outer surface of the second filter disc 13, and a power module 5 at the front end of the side plate 3.

[0026] In this embodiment, the main device 6 includes an electric push rod 61 and an adjusting valve plate 67. The output end of the electric push rod 61 passes through the side plate 3 and is fixedly connected to a rack block 63. A slider 62 is fixedly connected to the rear end of the rack block 63. A gear block 64 is meshed with the surface of the rack block 63. A connecting rod 65 is inserted and fixedly connected to the front end of the gear block 64. An installation groove 66 is opened on the front of the outer surface of the adjusting valve plate 67. The adjusting valve plate 67 is fixedly connected to the rear end of the connecting rod 65. The electric push rod 61 is fixedly connected to the right end of the side plate 3. The position and size of the mating strip 9 are adapted to the position and size of the mating groove 10, and the mating strip 9 are distributed in a ring at equal intervals around the water pipe 2. On the left side of the inner wall of water pipe 2, the structure of the first filter disc 8 is the same as that of the second filter disc 13 and they are symmetrically distributed. The mesh diameter of the insertion rod 12 is larger than that of the second filter screen 14. The connecting rod 65 has a T-shaped structure and is slidably connected in the groove 4. The front end of the connecting rod 65 is movably connected to the side plate 3 through a bearing. The diameter of the regulating valve plate 67 is adapted to the inner diameter of water pipe 2. The gear block 64 has a circular gear structure. Several teeth are evenly distributed on the outer surface of the gear block 64. The gear block 64 is meshed with the teeth on the surface of the rack block 63 through the teeth. The axis of the gear block 64 coincides with the axis of the connecting rod 65.

[0027] Through the above scheme: When the drain valve is working, water flows through the cavity 7 of the water pipe 2. The flanges 1 at both ends of the water pipe 2 are used to connect the drainage equipment. After the power module 5 supplies power, the electric push rod 61 pushes the rack block 63. The slider 62 at the rear end of the rack block 63 slides in the slide groove 4 to ensure movement stability. The rack block 63 drives the gear block 64 to rotate. The gear block 64 drives the regulating valve plate 67 to rotate through the connecting rod 65. Because the diameter of the regulating valve plate 67 is adapted to the inner diameter of the water pipe 2, the flow rate can be precisely adjusted. During water filtration, the first filter disc 8 and the second filter disc 13 pass through... The docking groove 10 engages with the docking strip 9 inside the water pipe 2. The first filter screen 11 and the second filter screen 14 intercept impurities. The mesh diameter of the insert rod 12 is larger than that of the second filter screen 14, achieving multi-stage filtration. The beneficial effects of this valve are that the electric push rod 61, combined with the gear and rack transmission, enables precise rotation of the regulating valve plate 67, improving flow control accuracy. The annularly distributed docking strips 9 and the symmetrical filter circular plate structure ensure filtration stability. The multi-stage filtration design enhances the impurity interception effect. The entire valve is made of corrosion-resistant materials, extending its service life. It is suitable for various drainage equipment.

[0028] It should be noted that this utility model is a corrosion-resistant drainage valve. When the corrosion-resistant drainage valve is working, water flows through the cavity 7 of the water pipe 2. The flanges 1 at both ends of the water pipe 2 are used to connect to the drainage equipment. Both the water pipe 2 and the flanges 1 are made of corrosion-resistant materials to resist water erosion. The power module 5 at the front end of the side plate 3 supplies power to the entire device. The electric push rod 61 in the main device 6 is fixed to the right end of the side plate 3. After the electric push rod 61 is started, its output end pushes the rack block 63 to move. The slider 62 at the rear end of the rack block 63 slides in the groove 4 at the front of the outer surface of the water pipe 2 to ensure the stability of the movement. The rack block 63 drives the gear block 64 that meshes with it to rotate. The gear block 64 drives the regulating valve plate 67 to rotate through the connecting rod 65. Since the diameter of the regulating valve plate 67 is adapted to the inner diameter of the water pipe 2, the water flow rate can be adjusted by adjusting the rotation angle of the regulating valve plate 67. All components of the main device 6 are treated with anti-corrosion to ensure that they can withstand humid environments. During normal operation, when water flows through water pipe 2, the first filter disc 8 and the second filter disc 13, which are engaged with the left wall of water pipe 2, filter the water flow. The first filter disc 8 and the second filter disc 13 intercept impurities through the first filter screen 11 and the second filter screen 14, respectively. The mesh diameter of the insert rod 12 is larger than that of the second filter screen 14 to ensure the filtration effect. The first filter disc 8 and the second filter disc 13 are installed by six mating grooves 10 on their outer surfaces and six mating strips 9 on the left wall of water pipe 2. The mating strips 9 are distributed in a ring with equal spacing around water pipe 2 to achieve a stable installation. At the same time, the first filter disc 8 and the second filter disc 13 have the same structure and are symmetrically distributed from left to right to ensure the uniformity and stability of filtration. The first filter disc 8, the second filter disc 13, the first filter screen 11 and the second filter screen 14 are all made of corrosion-resistant materials, which can effectively prevent corrosion by corrosive substances in the water and extend the service life of the valve.
