Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, and particularly relates to a copper gate valve. Background Technique

[0002] Gate valves are widely used in industrial equipment, and their closing members are generally composed of a gate plate and a valve seat. The pressing force of the gate plate against the valve seat is controlled by the medium pressure acting on the gate plate. The medium pushes the gate plate to press against the valve seat to form a seal. However, the existing copper gate valves cannot effectively buffer the water flow during use, which will cause excessive water flow impact and damage to the gate plate, reducing the service life of the gate plate and lowering its use efficiency and working efficiency. Therefore, we propose a copper gate valve. Content of the Utility Model

[0003] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a copper gate valve that can effectively buffer the water flow, thereby effectively avoiding the damage to the gate plate caused by excessive water flow impact, extending the service life of the gate plate, and improving its use efficiency and working efficiency.

[0004] To achieve the above purpose, a copper gate valve is provided, including: a block body. Both the left and right sides of the block body are connected with flow guide pipes through bolts, and a liquid guide groove communicating with the two block bodies is opened on the side wall of the block body. The bottom of the inner cavity of the liquid guide groove is attached to a valve plate, and a groove is opened at the top of the inner cavity of the liquid guide groove. The top of the block body is movably connected with a threaded pipe, and the top of the threaded pipe is closed. A handle is arranged above the threaded pipe, and a valve rod penetrates through the handle. A threaded hole matching the valve rod is opened at the top of the threaded pipe, and the bottom end of the valve rod passes through the threaded hole and extends into the groove and is movably connected to the top of the valve plate through a bearing. Right-angled trapezoidal plates are attached to both the left and right sides of the valve plate near the top, and the tops of the right-angled trapezoidal plates are connected to the top of the inner cavity of the liquid guide groove through bolts. Circular plates are welded to both the bottom of the threaded pipe and the top of the block body, and a fixing screw is connected between the two circular plates. Buffer inclined plates are connected to the top of the inner cavity of both flow guide pipes near the outside through bolts, and the two buffer inclined plates are symmetrically arranged left and right with the central axis of the block body as the symmetry axis. A filter screen is connected to the flow guide pipe near the liquid guide groove through bolts. A number of uniformly distributed buffer blocks are installed at the bottom of the right-angled trapezoidal plate.

[0005] According to the described copper gate valve, a mounting plate is sleeved on the side of the flow guide pipe away from the block body, and mounting holes are opened on the mounting plate.

[0006] According to the described copper gate valve, a sealing ring matching the valve plate is sleeved in the groove.

[0007] The above solution has at least one of the following beneficial effects: Through the mutual cooperation among components such as the buffer inclined plate, right-angled trapezoidal plate, and buffer block, this technical solution can effectively buffer the water flow, thereby effectively avoiding damage to the gate caused by excessive water flow impact, extending the service life of the gate, and improving its usage efficiency and working efficiency.

[0016] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0017] Refer to Figures 1 to 4, an embodiment of the utility model is a copper gate valve, which comprises a block 1. Flow guide pipes 3 are connected to both the left and right sides of the block 1 by bolts. A liquid guide groove 10 communicating with the two blocks 1 is formed in the side wall of the block 1. A valve plate 2 is attached to the bottom of the inner cavity of the liquid guide groove 10. A groove 14 is formed in the top of the inner cavity of the liquid guide groove 10. A threaded pipe 7 is movably connected to the top of the block 1, and the top of the threaded pipe 7 is closed. Circular plates 6 are welded to the bottom of the threaded pipe 7 and the top of the block 1 respectively, and a fixing screw rod is connected between the two circular plates 6. A handle 8 is arranged above the threaded pipe 7, and a valve rod 9 penetrates through the handle 8. A screw hole matching with the valve rod 9 is formed in the top of the threaded pipe 7, and the bottom end of the valve rod 9 passes through the screw hole and extends into the groove 14 and is movably connected to the top of the valve plate 2 through a bearing.

[0018] Right-angled trapezoidal plates 13 are attached to both the left and right sides of the valve plate 2 near the top, and the tops of the right-angled trapezoidal plates 13 are connected to the top of the inner cavity of the liquid guide groove 10 by bolts. Buffer inclined plates 16 are connected to the top of the inner cavity of both flow guide pipes 3 near the outside by bolts. The two buffer inclined plates 16 are symmetrically arranged left and right with the central axis of the block 1 as the symmetry axis. A filter screen 11 is connected to the flow guide pipe 3 near the liquid guide groove 10 by bolts. A number of buffer blocks 12 evenly distributed are installed on the bottom of the right-angled trapezoidal plate 13. Through this structure, the water flow can be effectively buffered, thereby effectively avoiding the damage to the gate plate caused by excessive water flow impact, prolonging the service life of the gate plate, and improving its use efficiency and working efficiency.

[0019] An installation plate 5 is sleeved on the side of the flow guide pipe 3 away from the block 1, and an installation hole 4 is formed in the installation plate 5. A sealing ring 15 matching with the valve plate 2 is sleeved in the groove 14. Through this structure, convenient installation and effective sealing can be achieved.

[0020] Working principle: When this technical solution is used, it is first installed and docked conveniently through the two installation plates 5 and the installation holes 4. The handle 8 is rotated clockwise first and then counterclockwise. The handle 8 drives the valve rod 9 to rotate clockwise or counterclockwise, so that the valve rod 9 moves up or down in the threaded pipe 7. The valve rod 9 drives the valve plate 2 to move up or down in the liquid guide groove 10 and the groove 14, and the flow-through and cut-off can be realized. The water flow passes through the buffer inclined plate 16 and the buffer blocks 12 on the right-angled trapezoidal plate 13, and the water flow can be effectively buffered, thereby effectively avoiding the damage to the gate plate caused by excessive water flow impact, prolonging the service life of the gate plate, and improving its use efficiency and working efficiency.
