Description

Technical Field

[0001] This utility model relates to the field of mud discharge valve technology, and more specifically, to a separate mud discharge valve. Background Technology

[0002] Currently, the most commonly used sludge discharge valve in waterworks is the piston-type sludge discharge valve. However, the gap between the piston and the valve body is small, making it prone to jamming due to particles, impurities, or sediment in the medium, causing the valve to fail to open and close properly. When handling high-viscosity media or media containing large particles, the piston movement is inflexible and may even become completely blocked. This leads to valve failure and affects the normal operation of the system. Frequent disassembly and cleaning are required, increasing maintenance costs and time. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a separate sludge discharge valve, including a valve body 10, a fixing member 20 on one side of the valve body 10, a valve stem 2001 movably mounted on the fixing member 20, a piston 2002 at one end of the valve stem 2001 fixedly mounted on the top of the valve stem 2001, a valve disc 2003 at the other end of the valve stem 2001 fixedly connected to the bottom end of the valve stem 2001, a piston cavity 2004 formed inside the fixing member 20, and a sludge scraper ring 1005 mounted on the fixing member 20. A mounting plate 30 is provided on one side, and an air supply device 3001 is provided on the mounting plate 30. The air supply device 3001 can be electrically connected to the outside. An air supply hose 3002 is provided on the air supply device 3001. The other end of the air supply hose 3002 is connected to the piston chamber 2004. A fixing hole is provided on one side of the fixing member 20. The air supply hose 3002 is fixed to the fixing hole. Multiple springs 2006 are provided inside the fixing member 20. A second buffer pad 2007 is fixedly connected to one end of the multiple springs 2006. A first buffer pad 1006 is provided inside the valve body 10.

[0028] In this embodiment, the solution provides a second buffer pad 2007 above the piston 2002 and a first buffer pad 1006 below the valve disc 2003, respectively. The second buffer pad 2007 and the first buffer pad 1006 are made of elastic damping material, which can prevent the piston 2002 from impacting the fixing member 20 and the valve body 10 when moving upward and downward.

[0029] In this embodiment, the valve body 10 has an inlet 1001 on one side and a sludge discharge port 1002 on the other side. Both the inlet 1001 and the sludge discharge port 1002 are provided with sealing rings. A sealing plate 1003 is fixedly installed on the top of the valve body 10 and is bolted to the valve body 10.

[0030] In this embodiment, a valve disc cavity 1004 is formed inside the valve body 10. A plurality of throttling holes 1007 are provided on the sealing plate 1003. The throttling holes 1007 connect the piston cavity 2004 and the valve disc cavity 1004. An anti-slip washer 1008 is fixedly provided inside the valve disc cavity 1004. When the valve disc 2003 is opened, the anti-slip washer 1008 is in clearance fit with the valve disc 2003, which can prevent mud and sand from entering above the valve disc 2003 and effectively prevent mud and sand blockage.

[0031] In this embodiment, a fixing ring 2005 is fixedly provided on the inner top wall of the fixing member 20, and multiple springs 2006 are fixedly provided in a circumferentially equidistant manner within the fixing ring 2005. The second buffer pad 2007 is located directly above the piston 2002, and the diameter of the second buffer pad 2007 is larger than the diameter of the piston 2002. When the piston 2002 moves upward and compresses the second buffer pad 2007, the second buffer pad 2007 compresses the springs 2006 and gives the springs 2006 elastic potential energy in the opposite direction. During the upward movement of the piston 2002, the second buffer pad 2007 and the springs 2006 can buffer the piston 2002 and prevent the piston 2002 from impacting the fixing member 20.

[0032] In this embodiment, the bottom of the fixing ring 2005 is designed to be open, a groove 2008 is provided on the inner peripheral wall of the fixing ring 2005, and a slider 2009 is fixedly provided on the outer periphery of the second buffer pad 2007.

[0033] In this embodiment, the slider 2009 has a ring-shaped design and is slidably connected to the groove 2008.

[0034] In this embodiment, the top of the valve body 10 is provided with multiple threaded grooves, which are distributed circumferentially at equal intervals on the top of the valve body 10. The sealing plate 1003 is provided with multiple through holes, the number of which is equal to the number of threaded grooves.

[0035] In this embodiment, a plurality of telescopic rods 3003 are rotatably provided at the bottom of the mounting plate 30. A screw 3004 is fixedly provided at the bottom end of the telescopic rod 3003. The telescopic rod 3003 is slidably connected to the through hole. When installing the mounting plate 30, the telescopic rod 3003 is pulled and the screw 3004 is aligned with the thread groove. The telescopic rod 3003 is then rotated so that the screw 3004 is fully rotated into the thread groove. At this time, the telescopic rod 3003 is in a fully extended state and cannot be extended further. At this time, the mounting plate 30 is tightly fitted with the top surface of the fixing member 20. That is, the safety plate cannot be moved up or down after installation. If it is necessary to inspect the inside of the valve body 10, the sealing plate 1003 can be removed from the top of the valve body 10 and the sealing plate 1003 can be slid upward to inspect the inside of the valve body 10. It is not necessary to completely remove the sealing plate, which reduces the time and cost of maintenance.

[0036] In this embodiment, the number of screws 3004 is the same as the number of threaded grooves, and the screws 3004 are threadedly connected to the threaded grooves.

[0037] In this embodiment, the scraper ring 1005 and the valve stem 2001 are fitted with a clearance. During the up-and-down movement of the valve stem 2001, the scraper ring 1005 can remove the fine mud and sand adsorbed on the valve stem 2001, preventing excessive wear on the rod. At the same time, it avoids the mud and sand adsorbed on the valve stem 2001 from being carried into the piston chamber 2004, which would prevent the piston 2002 from moving and cause blockage.

[0038] Specifically, the working principle of this separate mud discharge valve is as follows: In use, first, the telescopic rod 3003 is inserted through the through hole on the sealing plate 1003. Then, the screw 3004 is aligned with the threaded groove on the valve body 10, and the telescopic rod 3003 is rotated until the screw 3004 is fully rotated into the threaded groove. Next, the sealing plate 1003 is fixedly installed onto the valve body 10 using bolts. Subsequently, the inlet 1001 can be fixedly installed to the external drain pipe. In use, gas is supplied to the piston chamber 2004 through the air supply device 3001 via the air supply pipe, thereby pushing the piston 2002 upward and causing the valve disc 2003 to move upward. During the upward movement of the valve disc 2003… The sludge scraper ring 1005 can remove fine mud and sand adsorbed on the valve stem 2001 to prevent excessive wear on the stem. At the same time, it prevents the mud and sand adsorbed on the valve stem 2001 from being carried into the piston chamber 2004, which would cause the piston 2002 to be unable to move and thus cause blockage. When the piston 2002 moves close to the second buffer pad 2007 and continues to move, the piston 2002 squeezes the second buffer pad 2007, and the second buffer pad 2007 squeezes the spring 2006. This process can buffer the piston 2002 until the valve disc 2003 moves to the anti-slip washer 1008. At this time, the sludge can flow in through the water inlet 1001 and drain through the sludge outlet 1002.

[0039] The power supply and principle of the gas transmission device 3001 are clear to those skilled in the art and will not be described in detail here.
