Description

Technical Field

[0001] This application belongs to the field of automatic sewage valve technology, specifically an automatic sewage valve. Background Technology

[0002] Automatic drain valves are key devices used to automatically remove sediment and impurities from liquids, and are widely used in water storage tanks, pipeline systems, and industrial fluid handling.

[0003] Automatic drain valves are typically installed at the bottom of the water storage tank or on the drain pipe. After impurities settle, the valve is opened by a preset program or sensor signal to achieve automatic draining. This design effectively reduces the frequency of manual cleaning and ensures the long-term stable operation of the water storage tank.

[0004] Automatic sewage valves typically rely on sealing rings for sealing. However, due to prolonged contact with sewage, particulate matter, and corrosive media, the sealing rings are prone to wear and aging, leading to sealing failure. To ensure the valve's sealing performance, the sealing rings need to be replaced regularly. However, the valve plate is located inside the valve, where space is limited, making the disassembly and replacement of the sealing rings inconvenient and significantly increasing maintenance difficulty and downtime. Therefore, an automatic sewage valve is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing technologies by setting up a disassembly and assembly mechanism that enables the rapid installation and disassembly of the valve plate. This allows workers to easily remove the valve plate and readily replace the inner and outer sealing rings that are snapped onto its inner wall, thus solving the problem of inconvenient replacement of the valve plate sealing rings inside automatic sewage valves in existing technologies.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] An automatic sewage discharge valve includes a valve body, a sewage discharge pipe fixedly connected to one side of the valve body, a cylinder fixedly connected to the other side of the valve body, a chuck fixedly connected to the piston end of the cylinder, a valve plate clamped to the outer wall of the chuck, an inner sealing ring and an outer sealing ring clamped to the inner wall of the valve plate, and a disassembly and assembly mechanism and an auxiliary mechanism provided inside the chuck.

[0008] The disassembly and assembly mechanism includes a protrusion fixedly connected to the outer wall of the chuck. The protrusion has slots at both its upper and lower ends. A concave block is fixedly connected to the outer wall of the valve plate. A slidable inclined block is slidably connected to the inner wall of the concave block. One end of the inclined block is engaged with the inner wall of the slot. An L-rod is fixedly connected to the other end of the inclined block. A spring is sleeved on the outer wall of the L-rod. A turntable is rotatably connected to the right side of the valve plate. An arc-shaped block is fixedly connected to the inner wall of the turntable. A handle is fixedly connected to the right side of the turntable.

[0009] Preferably, the auxiliary mechanism includes a push rod, which is slidably connected to the inner wall of the valve plate.

[0010] Preferably, the turntable has an inclined groove on its left side.

[0011] Preferably, a sliding shaft is fixedly connected to the outer wall of the top rod, and the end of the sliding shaft away from the top rod is attached to the inner wall of the inclined groove.

[0012] Preferably, one end of the spring is fixedly connected to the inner wall of the concave block, and the other end of the spring is fixedly connected to the outer wall of the inclined block.

[0013] Preferably, the L-bar is an "L"-shaped rod structure, with the end of the L-bar away from the inclined block penetrating the concave block and extending into the interior of the turntable, and fitting against the outer wall of the arc-shaped block.

[0014] Preferably, the outer wall of the inner sealing ring is snapped onto the inner wall of the valve plate, and the outer wall of the inner sealing ring is tightly fitted with the outer wall of the chuck.

[0015] Preferably, the inner wall of the outer sealing ring is engaged with the inner wall of the valve plate, and the outer wall of the outer sealing ring is tightly fitted with the inner wall of the drain pipe.

[0016] This application has the following beneficial effects:

[0017] 1. This application enables the rapid installation and disassembly of the valve plate through the design of the disassembly and assembly mechanism. This allows workers to easily remove the valve plate and replace the inner and outer sealing rings that are snapped onto its inner wall. This not only significantly reduces the difficulty of valve maintenance but also effectively reduces downtime and significantly improves the reliability and ease of maintenance of the drain valve in the long term.

[0018] 2. This application, through the setting of an auxiliary mechanism, can push the inner and outer sealing rings outwards towards the outside of the valve plate, thereby allowing the inner and outer sealing rings to protrude outwards from the valve plate, so that the staff can pry the inner and outer sealing rings out from the inside of the valve plate, thereby further improving the convenience of replacing the inner and outer sealing rings.

[0027] like Figure 1-3 As shown, an automatic sewage discharge valve includes a valve body 1. A sewage discharge pipe 2 is fixedly connected to one side of the valve body 1, through which impurities in sewage can be discharged from the valve body 1. A cylinder 3 is fixedly connected to the other side of the valve body 1. A chuck 4 is fixedly connected to the piston end of the cylinder 3. A valve plate 5 is clamped to the outer wall of the chuck 4. By activating the cylinder 3 in conjunction with the chuck 4 and the valve plate 5, the opening and closing of the sewage discharge pipe 2 can be controlled. An inner sealing ring 6 and an outer sealing ring 7 are clamped to the inner wall of the valve plate 5. The outer wall of the inner sealing ring 6 is clamped to the inner wall of the valve plate 5, and the outer wall of the inner sealing ring 6 is tightly fitted to the outer wall of the chuck 4. The inner sealing ring 6 can seal the connection between the chuck 4 and the valve plate 5. The inner wall of the outer sealing ring 7 is clamped to the inner wall of the valve plate 5, and the outer wall of the outer sealing ring 7 is tightly fitted to the inner wall of the sewage discharge pipe 2. The outer sealing ring 7 can seal the connection between the valve plate 5 and the sewage discharge pipe 2. The chuck 4 is internally provided with a disassembly and assembly mechanism 8 and an auxiliary mechanism 9.

[0028] like Figure 3 , Figure 5 , Figure 7As shown, the disassembly and assembly mechanism 8 includes a protrusion 81, which is fixedly connected to the outer wall of the chuck 4. Both ends of the protrusion 81 have slots 82. A concave block 83 is fixedly connected to the outer wall of the valve plate 5. A sloping block 84 is slidably connected to the inner wall of the concave block 83. The sloping block 84, in conjunction with the slots 82, can limit the concave block 83 and the protrusion 81 together, thereby fixing the valve plate 5 and the chuck 4 together. One end of the sloping block 84 is engaged with the inner wall of the slot 82, and the other end is fixedly connected to an L-shaped rod 85. By pulling the sloping block 84 with the L-shaped rod 85, the sloping block 84 slides on the inner wall of the concave block 83 and compresses the spring 86, thereby allowing the sloping block 84 to move out of the slot 82. The L-shaped rod 85 is an "L"-shaped rod. The structure consists of an L-shaped rod 85, with one end of the rod away from the inclined block 84 passing through the recess 83 and extending into the interior of the turntable 87, where it fits against the outer wall of the arc-shaped block 88. The rotation of the turntable 87 allows the arc-shaped block 88 on its inner wall to press against the L-shaped rod 85. A spring 86 is fitted on the outer wall of the L-shaped rod 85, with one end of the spring 86 fixedly connected to the inner wall of the recess 83 and the other end fixedly connected to the outer wall of the inclined block 84. The elasticity of the spring 86 can push the inclined block 84 to slide and reset on the inner wall of the recess 83. The valve plate 5 is rotatably connected to the turntable 87, with the arc-shaped block 88 fixedly connected to the inner wall of the turntable 87. A handle 89 is fixedly connected to the right side of the turntable 87, allowing the turntable 87 to be rotated or pushed / pushed via the handle 89.

[0029] like Figure 4-6 As shown, the auxiliary mechanism 9 includes a push rod 91, which is slidably connected to the inner wall of the valve plate 5. By sliding the two sets of push rods 91 in opposite directions, the inner sealing ring 6 and the outer sealing ring 7 can be pushed out of the valve plate 5, so that the operator can remove the inner sealing ring 6 and the outer sealing ring 7 from the inside of the valve plate 5. A slanted groove 93 is provided on the left side of the turntable 87. A sliding shaft 92 is fixedly connected to the outer wall of the push rod 91. The end of the sliding shaft 92 away from the push rod 91 is attached to the inner wall of the slanted groove 93. When the turntable 87 rotates, the slanted groove 93 on its left side will squeeze the sliding shaft 92, so that the sliding shaft 92 pushes the push rod 91 to slide on the inner wall of the valve plate 5.

[0030] In use, the bottom of valve body 1 is connected to the sewage pipe at the bottom of the water storage tank via flange and bolts. Then, the sedimentation pipe is connected to the top of valve body 1 via flange and bolts, so that the water level inside the sedimentation pipe at the top of valve body 1 is level with the water level inside the water storage tank. At this time, the impurities inside the sedimentation pipe will gradually settle downwards. After the impurities have settled and accumulated, the cylinder 3 is activated in conjunction with the chuck 4 to move the valve plate 5 from the inside of the drain pipe 2 to the inside of valve body 1, thereby opening the drain pipe 2. At this time, the impurities settled inside the sedimentation pipe at the top of valve body 1 will be discharged outwards through the drain pipe 2. After the impurities are cleared, the cylinder 3 is activated again in conjunction with the chuck 4 to move the valve plate 5 into the inside of the drain pipe 2. The drain pipe 2 is sealed by the valve plate 5 in conjunction with the outer sealing ring 7. At the same time, the sewage inside the water storage tank will be discharged back into the inside of valve body 1 through the sewage pipe at its bottom and enter the sedimentation pipe at the top of valve body 1 for sedimentation.

[0031] When it is necessary to replace the inner sealing ring 6 and the outer sealing ring 7, first rotate the turntable 87 counterclockwise by holding the handle 89, so that the arc-shaped block 88 on the inner wall of the turntable 87 presses the L rod 85. At this time, the L rod 85 will pull the inclined block 84, so that the inclined block 84 slides on the inner wall of the concave block 83 and compresses the spring 86. At the same time, the inclined block 84 will gradually move out of the slot 82. When the inclined block 84 is completely moved out of the slot 82, the limiting of the protrusion 81 can be released. Then, pull the turntable 87 outward by holding the handle 89, so that the turntable 87 drives the valve plate 5 to separate from the chuck 4, so that the valve plate 5 can be removed from the inside of the valve body 1, so that the inner sealing ring 6 and the outer sealing ring 7 that are stuck on the inner wall of the valve plate 5 can be disassembled.

[0032] After the inner sealing ring 6 and outer sealing ring 7 are replaced, the valve plate 5 needs to be installed. Align the concave block 83 with the protrusion 81, and then assemble the valve plate 5 with the chuck 4, so that the concave block 83 fits on the outer wall of the protrusion 81. At the same time, during the assembly process of the concave block 83 and the protrusion 81, when the protrusion 81 contacts the inclined block 84, the protrusion 81 will squeeze the inclined block 84, causing the inclined block 84 to slide into the concave block 83 and compress the spring 86. As the concave block 83 continues to advance, the inclined block 84 will gradually approach the slot 82. When the inclined block 84 and the slot 82 are completely overlapped, the elasticity of the spring 86 can push the inclined block 84 to slide and reset on the inner wall of the concave block 83, so that the inclined block 84 can be inserted into the inside of the slot 82. At this time, the inclined block 84 and the slot 82 can limit the concave block 83 and the protrusion 81 together, and then fix the valve plate 5 and the chuck 4 together, thus completing the installation of the valve plate 5.

[0033] After the valve plate 5 is removed from the inside of the valve body 1, the turntable 87 is rotated clockwise by the handle 89. At this time, the inclined groove 93 on the left side of the turntable 87 will squeeze the sliding shaft 92, causing the sliding shaft 92 to push the push rod 91. At this time, the two sets of push rods 91 will slide in opposite directions on the inner wall of the valve plate 5, so that one set of push rods 91 gradually approaches the inner sealing ring 6, and the other set of push rods 91 gradually approaches the outer sealing ring 7. At this time, the two sets of push rods 91 sliding in opposite directions can push the inner sealing ring 6 and the outer sealing ring 7 outward of the valve plate 5, so that the inner sealing ring 6 and the outer sealing ring 7 can protrude outward of the valve plate 5, so that the operator can pry the inner sealing ring 6 and the outer sealing ring 7 out of the inside of the valve plate 5.
