[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. They have functions such as cut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. After a certain period of use, the solid particles in the liquid will accumulate inside the valve tube, causing the valve to be blocked. When unblocking the valve, a liquid pressurizing device can be used to pressurize the liquid to impact the inside of the valve tube for unblocking.

[0003] When the existing valve is pressurized for unblocking, it is necessary to use bolts to connect the water storage pipe and the valve pipe, and push the extruded piston rod to pressurize the liquid inside the water storage pipe and input it into the valve pipe to impact and unblock the blocked position. When installing or disassembling the water storage pipe, it is necessary to turn multiple sets of bolts, and the installation or disassembly of the water storage pipe is not quick and convenient enough. Therefore, improvement is needed. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a valve with a dredging and anti-blocking structure, which solves the problem that the existing valves need to tighten multiple sets of bolts when installing or disassembling the water storage pipe, and the installation or disassembly of the water storage pipe is not fast and convenient enough.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a valve with a dredging and anti-blocking structure, comprising a valve tube 1, valve tubes 2 are fixedly installed on both sides of the surface of the valve tube 1, a connecting sleeve is provided on the surface of the valve tube 2 located away from the valve tube 1, mounting rods are fixedly installed at the four corners on both sides of the connecting sleeve, and four groups of mounting rods are slidably installed with clamping plates on the surface of one end away from the connecting sleeve, one end of the four groups of mounting rods passes through the clamping plate and is fixedly installed with an I-shaped connecting plate, a clamping spring is provided on the surface of the mounting rod between the connecting sleeve and the clamping plate, a fixing protrusion is fixedly installed at the central position of one side of the clamping plate, a right-angle through pipe is fixedly installed on the end of the connecting sleeve away from the valve tube 2, and a water storage pipe is fixedly installed on the top of the right-angle through pipe.

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a valve with a dredging and anti-blocking structure, comprising a valve tube 1, a valve core 2 is rotatably installed at the central position inside the valve tube 1, and a hand wheel 3 is fixedly installed on the top of the valve core 2 through the valve tube 1. Because the valve core 2 is provided, the hand wheel 3 is turned to drive the valve core 2 to rotate inside the valve tube 1, thereby controlling the on-off of the liquid inside the valve tube 1;

[0021] Valve tubes 24 are fixedly installed on both sides of the surface of the valve tube 1, and a valve core 25 is rotatably installed on one side of the inside of the valve tube 4. A hand wheel 26 is fixedly installed on the top of the valve core 25 through the valve tube 24. Because the valve core 25 is provided, the hand wheel 26 is turned to control the valve core 25 to rotate inside the valve tube 24, so that the liquid at the bottom of the valve tube 1 can be input into the water storage pipe 18.

[0022] An end plate 7 is fixedly installed on the surface of the valve tube 2 4, which is located on the side of the valve core 2 5 away from the valve tube 1 1. Fixed grooves 8 are symmetrically provided at the central positions on both sides of the end plate 7, and the fixed grooves 8 correspond to the fixed protrusions 16. Due to the provision of the end plate 7, after the connecting sleeve 10 is sleeved on the surface of the valve tube 2 4, the connecting sleeve 10 is tightly attached to the end plate 7, thereby limiting the position of the connecting sleeve 10 on the surface of the valve tube 2 4.

[0023] A connecting sleeve 10 is provided on the surface of the valve tube 2 4 which is located away from the valve tube 1 1, and six groups of limit strips 9 are fixedly installed at equal angles on the surface of the valve tube 2 4 which is located on one side of the end plate 7. Six groups of limit grooves 11 are provided at equal angles on one end of the inner wall of the connecting sleeve 10, and the limit grooves 11 correspond to the limit strips 9. By providing the limit strips 9 and the limit grooves 11, after the connecting sleeve 10 is sleeved on the surface of the valve tube 2 4, the limit grooves 11 are stuck on the corresponding surfaces of the limit strips 9, ensuring that the connecting sleeve 10 is sleeved on the surface of the valve tube 2 4 and will not deflect or become misaligned at will.

[0024] Mounting rods 12 are fixedly installed at the four corners on both sides of the connecting sleeve 10, and a clamping plate 13 is slidably installed on the surface of one end of the four groups of mounting rods 12 away from the connecting sleeve 10. One end of the four groups of mounting rods 12 passes through the clamping plate 13 and is fixedly installed with an I-type connecting plate 14. A clamping spring 15 is provided on the surface of the mounting rod 12 located between the connecting sleeve 10 and the clamping plate 13. A fixing protrusion 16 is fixedly installed at the central position of one side of the clamping plate 13. A right-angle through pipe 17 is fixedly installed at the end of the connecting sleeve 10 away from the valve pipe 24, and a water storage pipe 18 is fixedly installed at the top of the right-angle through pipe 17. Because a clamping spring 15 is provided, the clamping plate 13 is pushed toward the end away from the connecting sleeve 10 under the elastic action of the clamping spring 15, thereby driving the fixing protrusion 16 to move to both sides of the connecting sleeve 10 and be clamped and fixed in the corresponding fixing groove 8.

[0025] A rubber piston head 19 is slidably mounted on one end of the water storage pipe 18 near the right-angle through pipe 17, a piston rod 20 is fixedly mounted on the side of the rubber piston head 19 away from the right-angle through pipe 17, and a pressure plate 21 is fixedly mounted on one end of the rubber piston head 19 through the piston rod 20. Electric push rods 22 are symmetrically fixedly mounted on both sides of the surface of the water storage pipe 18, and one end of the two groups of electric push rods 22 are fixed to the pressure plate 21. By providing the electric push rods 22, the electric push rods 22 are controlled to telescope with the piston rod 20 and the rubber piston head 19 to move inside the water storage pipe 18, so that the liquid inside the water storage pipe 18 is pressurized and pumped into the inside of the valve pipe 24.

[0026] The working principle of the utility model is:

[0027] When one end of the valve tube 1 is blocked, the two sets of clamping plates 13 are pushed and squeezed close to the connecting sleeve 10, and the connecting sleeve 10 is sleeved on the surface of the valve tube 2 4 at the blocked end of the valve tube 1 until the fixed protrusion 16 passes through the fixed groove 8. Then, the clamping plate 13 is released. Under the rebound action of the clamping spring 15, the clamping plate 13 drives the fixed protrusion 16 to move inside the fixed groove 8 to the side away from the connecting sleeve 10, so that the connecting sleeve 10 is clamped and fixed on the surface of the valve tube 2 4. The hand wheel 26 is turned to control the valve core 25 to open, and at the same time, the electric push rod 22 is controlled to extend. After the water storage pipe 18 is filled with liquid, the valve core 2 is closed, and the electric push rod 22 is controlled to contract, so that the piston rod 20 and the rubber piston head 19 move inside the water storage pipe 18 toward the right-angle through pipe 17, and the liquid inside the water storage pipe 18 is pressurized and input into the valve tube 24 and the blocked end of the valve tube 1, so as to flush the blocked position of the valve tube 1 for dredging.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
