Description

Technical Field

[0001] The utility model belongs to the technical field of check valve installation, in particular to a check valve which is easy to install. Background Art

[0002] A return valve is a valve whose opening and closing part is a circular disc and which relies on its own weight and medium pressure to produce movement to block the backflow of the medium. It belongs to the category of automatic valves and is also called a check valve, a one-way valve, a return valve or an isolation valve. The movement of the disc is divided into a lifting type and a swing type. The lifting check valve is similar in structure to the stop valve, except that it lacks a valve stem that drives the disc. The medium flows in from the inlet end and flows out from the outlet end. When the inlet pressure is greater than the sum of the weight of the disc and its flow resistance, the valve is opened. Conversely, the valve is closed when the medium flows back. The check valve is often used as a bottom valve of a pumping device to prevent the backflow of water. The check valve is used in combination with a stop valve to achieve a safe isolation effect.

[0003] A Chinese patent with publication number CN219866824U discloses a check valve that is easy to install. It includes a check valve body, two connecting pieces and multiple water inlet pipes; the connecting pieces are fixedly installed on both sides of the check valve body; and the water inlet pipe is movably installed in the connecting piece. The two connecting pieces include two connecting pipes, multiple shells, multiple moving rods, multiple pull rings, multiple buckle blocks and multiple springs; the two connecting pipes are fixedly installed on both sides of the check valve body; multiple shells are fixedly installed on the surface of the connecting pipe; a moving rod is movably connected in the shell, and a pull ring is fixedly installed on the outer end of the moving rod; a buckle block is fixedly installed on the other end of the moving rod and is located in the shell; a spring is sleeved on the surface of the moving rod, one end of the spring is connected to the buckle block, and the other end of the spring is connected to the shell, and the water inlet pipe is movably installed in the connecting pipe; a buckle ring is welded on the surface of the water inlet pipe port, thereby achieving portable installation and disassembly of the check valve body.

[0004] In the current prior art, the existing check valve and the pipeline are installed by multiple sets of bolts and clamps or flanges and multiple sets of bolts and nuts. However, the installation between the check valve and the pipeline requires workers to fix the multiple sets of bolts one by one using tools. Too many parts are required, and it is easy for a part to deform and bend, resulting in the inability of other parts to cooperate effectively. When installing and fixing, employees or equipment are required to lift the check valve, connect it to the pipeline, and then fix it with bolts. Manual handling is laborious and requires outsiders to observe and align it. When the mechanical equipment is lifted, the height and angle cannot be adjusted, and it cannot be quickly aligned.
