Description

Technical Field

[0001] The utility model mainly relates to the technical field of internal parts of a Y-type ball valve, in particular to a high-sealing Y-type ball valve. Background Art

[0002] In industrial piping systems, valves play an important role. They control the flow of fluids, protect the system from excessive pressure, and prevent accidental fluid leakage. Among them, the Y-type three-way ball valve is a special type of valve, which is widely used because of its unique structure and high functionality. The Y-type three-way ball valve is a device that controls the flow direction of fluids. Its core component is a spherical valve core. By controlling the position of the spherical valve core, the flow direction can be switched.

[0003] After searching, it is found that the utility model patent with announcement number CN211259734U discloses a Y-type three-way ball with good sealing performance, including a ball, circular openings are opened on the left front and right front of the ball, connecting blocks are fixedly installed on the top and bottom of the ball, annular grooves are opened on the upper and lower ends of the left side of the inner cavity of the ball, a spring is fixedly installed on the right side of the annular groove, a sleeve is fixedly installed on the other side of the spring, an annular sealing ring is fixedly installed on the other side of the sleeve, and a movable cylinder is fixedly installed on the right side of the sleeve; the Y-type three-way ball with good sealing performance is installed at the connection of three connecting pipes by setting a circular opening, and when one of the pipes needs to be blocked, the ball can be rotated so that the two circular openings opened on the ball are aligned with the two pipes that need to be connected, and the other pipe is fitted with the area on the ball where no circular opening is provided, thereby playing a role of flow blocking. The structure of the three-way ball is very simple, and the flow blocking adjustment method is convenient, thereby improving the practicality of the device.

[0004] In the above patented technical solution, by setting a sealing ring, a spring and a movable cylinder, due to the elastic effect of the spring, the sealing ring and the connected pipe are in a tight fit state, preventing the liquid inside the pipe from flowing out from the gap between the ball and the pipe and then flowing out from another blocked pipe, thereby improving the flow blocking efficiency of the device. However, the above patented technical solution still has the following shortcomings when used:

[0005] 1. When the above patented technical solution is used, the sealing is performed by the sealing ring. However, if the sealing is performed only by the sealing ring, the sealing effect is not good. When the sealing ring is worn and a gap appears, it is easy for the pipeline on the sealed side to leak, resulting in a decrease in the sealing quality.

[0006] 2. When the above patented technical solution is used, the sealing ring and the sleeve are fixedly connected. When the sealing ring is worn and can no longer provide sealing, the above patented technical solution cannot replace the damaged sealing ring alone, and the entire Y-type three-way ball needs to be replaced, resulting in a waste of resources, an increase in the cost of use, and inconvenience to the user.

[0007] Therefore, we provide a high-sealing Y-type ball valve to solve the defects in the above solutions. Utility Model Content

[0018] 2. The utility model provides a detachable sealing mechanism and sealing rings on the two end faces of the L-shaped water passage, which can cooperate with the sealing gasket for sealing. The reset spring can make the sealing ring fit tightly with the sealing gasket to prevent gaps. At the same time, after the sealing ring is worn due to repeated rotation, the maintenance personnel can open the top flange of the ball valve housing and then take out the ball.

When the high-sealing Y-type ball valve is used, the damaged sealing ring can be replaced separately without replacing the entire Y-type three-way ball, thereby avoiding waste, reducing the cost of use, and bringing convenience to the user.
