Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ball valves, in particular to a half-ball valve with a sealing structure. BACKGROUND

[0002] Nowadays, valves are control components in fluid conveying systems, with functions such as shut-off, regulation, flow guiding, anti-backflow, pressure stabilization, shunt or overflow pressure relief. The traditional eccentric half-ball valve is a one-way flow valve, and its valve seat is fixed, only having good sealing effect when the medium flows in the positive direction. When the medium flows in the reverse direction, the half-ball valve core will deform, and the fixed valve seat cannot deform with the valve core to achieve reverse sealing, resulting in leakage, which greatly reduces the applicability and versatility of the traditional half-ball valve. Ball valves are widely used in many fields such as industry, construction and life. Figure 3 As shown in the figure, for a large-diameter fixed ball valve, the support plate for fixing and limiting the ball is usually designed to extend into the middle cavity from the middle flange of the valve body during design, and an O-ring seal is designed at the middle flange.

[0003] A Chinese patent with publication number CN211203043U is proposed in the prior art to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a ball valve body, comprising symmetrically arranged left and right half valve bodies, the left and right half valve bodies are provided with a communication medium flow channel, a "V"-shaped annular groove is arranged on the connecting end face of the left and right half valve bodies, a "V"-shaped convex edge embedded in the annular groove is arranged on the connecting end face of the right half valve body and the left half valve body, and a rhombic sealing groove is arranged on the connecting end face of the left and right half valve bodies, and a rhombic sealing ring matched with the rhombic sealing groove is arranged in the rhombic sealing groove. By arranging the "V"-shaped annular groove and the "V"-shaped convex edge embedded in the annular groove on the connecting surface of the left and right half valve bodies, the annular groove and the convex edge provide a positioning structure for the assembly of the two half valve bodies, facilitating quick centering during assembly, realizing quick assembly of the left and right half valve bodies, and having the advantages of simple structure and low cost.

[0004] Although the ball valve body has a simple structure and low cost, the ball valve sealing effect is not good, which may cause inconvenience in using the ball valve and problems, and the ball valve needs to be driven by manual tightening, which increases the demand for manpower. SUMMARY
