Description

Technical Field

[0001] The present invention relates to a relief valve, and more particularly to a buoyancy automatic pressure - boosting relief valve. Background Art

[0002] Most of the existing sewage overflow pipes are directly connected with an overflow pipe on their own drain pipes. However, when large objects flow through such overflow pipes, the large objects in the overflow pipes often cannot be washed away due to insufficient water pressure, and finally the sewage flows back into the room. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device that uses water buoyancy to drain the sewage and the dirt mixed in the sewage during backflow to the overflow pipe and flow away.

[0004] To solve the above - mentioned technical problem, the present invention provides a buoyancy automatic pressure - boosting relief valve, which includes a body. The body is a cylinder, and a sealing ring is tightly fixed at the bottom of the body. The inner side of the sealing ring is tightly fixed with a drainage cylinder. An arc - shaped ring is tightly fixed above the body, and the inner side of the arc - shaped ring is tightly fixed with a drainage cylinder. The outer side above the drainage cylinder is tightly fixed with a positioning ring. When the positioning ring drops, it will be caught by the positioning ring and cannot continue to drop. The present invention with such a structure is simple in installation and use steps, and has a greater water pressure during the use process.

[0005] It is found in the experiment that the upper half of the arc - shaped ring can extend into the hollow circle of the positioning ring, making the contact between the arc - shaped ring and the positioning ring closer and seamless, playing a sealing role.

[0006] Furthermore, the lower half of the arc - shaped ring cannot extend into the hollow circle of the positioning ring, so that the lower part of the arc - shaped ring is stuck under the positioning ring, playing a sealing role.

[0007] Furthermore, the hollow part of the drainage cylinder can not only make the drainage smooth, but also make the backflow sewage flow to the overflow port.

[0008] Furthermore, the inner diameter of the positioning ring is smaller than the outer diameter of the positioning ring. When the positioning ring drops, it will be caught by the positioning ring and cannot continue to drop to cause blockage, making the water flow smooth.

[0009] Furthermore, the cylindrical hollow part between the body and the drainage cylinder contains air. When the sewage flows back, this part will float, so that the whole body floats and completes the upper - part sealing and overflow work.

[0010] Further, the total height of the upper half of the arc-shaped ring and the drainage cylinder above the arc-shaped ring is equal to the vertical distance from the bottom of the positioning ring to the overflow port, so that when the lower part of the arc-shaped ring is stuck below the positioning ring, it not only seals the arc-shaped ring but also makes the positioning ring in close contact with the overflow port to play an overflow role.

[0011] Further, the sealing ring seals the lower part of the cylindrical hollow part between the body and the drainage cylinder, so that water flow cannot enter the cylindrical hollow part.

[0012] In the present invention adopting this structure, when there is no sewage backflow, the newly used sewage from the toilet can smoothly drain into the main sewage pipe through the drainage cylinder and flow away. When there is sewage backflow, the cylindrical hollow part will automatically float upward, making the arc-shaped ring play a sealing role and making the positioning ring in close contact with the overflow port to play an overflow role. For this buoyancy automatic pressure-increasing overflow valve adopting this structure, the installation and separation steps are simple, the use process is automatic and the overflow water pressure is greater.

[0018] As Figure 1 , shown in FIGS. 2, 3, 4, 5, a buoyancy automatic pressure-increasing overflow valve includes a body (1), the body (1) is a cylinder, a sealing ring (8) is tightly fixed at the bottom of the body (1), and a drainage cylinder (9) is tightly fixed inside the sealing ring (8). An arc-shaped ring (10) is tightly fixed above the body (1), and a drainage cylinder (9) is tightly fixed inside the arc-shaped ring (10). A positioning ring (2) is tightly fixed on the outer side above the drainage cylinder (9), and when the positioning ring (2) falls, it will be received by the positioning ring (3) so that it cannot continue to fall. For the present invention adopting this structure, the installation and use steps are simple, the use process is automatic and the overflow water pressure is greater.

[0019] It was found in the experiment that the upper half of the arc-shaped ring (10) can extend into the hollow circle of the positioning ring (3), making the arc-shaped ring (10) contact the positioning ring (3) more closely and seamlessly, playing a sealing role.

[0020] Furthermore, the lower half of the arc-shaped ring (10) cannot extend into the hollow circle of the positioning ring (3), so that the lower part of the arc-shaped ring (10) is stuck under the positioning ring (3), playing a sealing role.

[0021] Furthermore, the hollow part of the drainage cylinder (9) can not only allow the sewage to flow smoothly, but also allow the refluxed sewage to flow towards the overflow port (4).

[0022] Furthermore, the inner diameter of the positioning ring (3) is smaller than the outer diameter of the clamping ring (2). When the clamping ring (2) falls, it will be received by the positioning ring (3) so that it cannot continue to fall and cause blockage, ensuring smooth water flow.

[0023] Furthermore, the cylindrical hollow part (11) between the main body (1) and the drainage cylinder (9) contains air. When the sewage refluxes, this part will float, so that the whole body floats and completes the upper sealing and overflow work.

[0024] Furthermore, the total height of the upper half of the arc-shaped ring (10) and the drainage cylinder (9) above the arc-shaped ring (10) is equal to the vertical distance from the bottom of the positioning ring (3) to the overflow port (4). When the lower part of the arc-shaped ring (10) is stuck under the positioning ring (3), it not only plays a sealing role for the arc-shaped ring (10), but also makes the clamping ring (2) and the overflow port (4) contact closely to play an overflow role.

[0025] Furthermore, the sealing ring (8) seals the lower part of the cylindrical hollow part (11) between the main body (1) and the drainage cylinder (9), so that water cannot enter the cylindrical hollow part (11).

[0026] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those of ordinary skill in the art.
