Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a ball valve with a check valve function. Background Technology

[0002] Ball valves are among the most widely used types of valves. They are durable, easy to operate, easy to manufacture, and convenient to maintain, as the opening and closing process involves simply rotating the valve ball. However, ball valves lack a check valve function. When the ball valve is open, the fluid in the outlet may flow back, potentially entering the upstream pipeline and causing contamination. Therefore, ball valves and check valves are used to control the flow of media in the pipeline. However, this method is cumbersome to install, requires multiple assembly steps, increases construction costs, and the ball in the ball valve is prone to deformation during prolonged impact. Therefore, to address the aforementioned problems, a ball valve with a check valve function has been developed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a ball valve with a check valve function, which addresses the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a ball valve with a check valve function, including a pipe body one, a connecting pipe provided on the outer wall of the pipe body one, a pipe body two provided on one side of the connecting pipe, and a check valve mechanism provided inside the pipe body two.

[0005] The check mechanism includes a rotating shaft;

[0006] The rotating shaft is rotatably connected inside the tube body two. A ball is installed on the outer wall of the rotating shaft. A rotating rod one is rotatably connected inside the rotating shaft. A plug is installed at the extended end of the rotating rod one. By rotating the rotating rod one, the plug is lowered after the ball closes, blocking the ball and preventing it from spinning back.

[0007] Preferably, a knob is installed on the upper extension end of the rotating rod one, and a sealing gasket is provided at the connection between the tube body two and the connecting tube.

[0008] Preferably, the connecting pipe is provided with a protective mechanism, which includes a bearing.

[0009] The bearing is installed inside the connecting pipe. A rotating rod is installed on the inner wall of the bearing. A pulley is sleeved on the upper extension end of the rotating rod. A protective plate is installed on the outer wall of the rotating rod.

[0010] Preferably, there are two sets of pulleys, with another set of pulleys mounted on the outer wall of the rotating rod, and the outer wall of the pulleys is connected to a belt.

[0011] Preferably, the protective plate is flexibly designed, and a sealing gasket is provided at the connection end between the rotating rod 2 and the connecting pipe. When the rotating rod 1 rotates, the rotating rod 2 is driven to rotate under the connection between the pulley 1 and the belt 1, thereby causing the protective plate cover to cover the water flow in the pipe body 1, preventing the water flow from continuously impacting the ball after the ball is closed.

[0012] Preferably, a collection trough is provided at the bottom of the connecting pipe, and the collection trough is connected to the connecting pipe. The collection trough facilitates the collection and treatment of internal impurities.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. A ball valve with a check valve function is connected to a pipe body 2 via a connecting pipe, and a check valve mechanism is provided inside the pipe body 2. A rotating shaft is provided inside the pipe body 2, a ball is provided on the outer wall of the rotating shaft, a plug is provided inside the ball, and a rotating rod 1 is installed on the plug. By rotating the rotating rod 1, the plug is lowered after the ball is closed, blocking the ball and preventing it from rotating back.

[0015] II. This ball valve with a check valve function rotates by rotating rod one, which drives rotating rod two to rotate under the connection of pulley one and belt one, thereby driving the protective cover plate to cover the water flow in pipe body one. After the ball is closed, it prevents the water flow from continuously impacting the ball and prevents the ball from deforming. Attached Figure Description
