Description

Technical Field

[0001] The utility model relates to the technical field of check valves, in particular to a spherical check valve. Background Art

[0002] Ball check valve, check valve is also called reverse flow valve, non-return valve, back pressure valve and one-way valve. This type of valve is automatically opened and closed by the force generated by the flow of the medium in the pipeline. It is an automatic valve. The ball check valve is a check valve with multi-ball, multi-channel and multi-cone reverse flow structure. It is mainly composed of front and rear valve bodies, rubber balls and cone bodies.

[0003] A ball check valve is a valve that can adjust water flow. When the existing ball check valve is in use, the staff may easily collide with the adjusting end of the ball valve while walking, resulting in the adjustment of the water flow in the pipeline, reducing the control effect of the ball check valve. Therefore, a ball check valve is proposed to solve the above problem. Utility Model Content

[0023] Working principle: During use, the valve body 1 is connected to the connecting pipe through the flange 3, and the valve body 1 is closed and opened by rotating the rocking wheel 5. When the rocking wheel 5 is rotated, the thumb pushes the two movable rods 12, so that the top of the movable rod 12 flips toward the center of the rocking wheel 5, and the movable rod 12 flips around the rotating shaft 13. The movable rod 12 squeezes the reed 14, and the reed 14 is deformed. The movable rod 12 drives the second clamping block 15 to flip away from the first clamping block 10, thereby releasing the fixation of the rocking wheel 5, and then the rocking wheel 5 is rotated to close and open the valve body 1. When the rocking wheel 5 rotates to a suitable position, the force on the movable rod 12 is released, and the movable rod 12 flips in the opposite direction under the elastic action of the reed 14. The movable rod 12 drives the second clamping block 15 to flip to engage with the first clamping block 10, thereby fixing the rocking wheel 5, thereby preventing the rocking wheel 5 from deflecting due to accidents, avoiding accidental adjustment of the water flow in the pipeline, and improving the control effect of the ball check valve.
