Problems solved by technology

However, most of the existing ball valves are made of two-piece castings or forgings, and there are many leakage points, many casting defects, pores or trachoma, and the preload pressure of the valve seat is not easy to control; and the ball of the existing ball valve is under the action of the fluid medium. It will be pushed to the outlet side, which will generate a driving force on the bottom of the valve stem, which will easily cause the valve stem to bend and deform. The service life is short and frequent maintenance is required, but the maintenance operation is difficult, inconvenient to use, and poor in practicability

Abstract

The invention discloses a high-safety die forging ball valve. The high-safety die forging ball valve comprises a valve body, wherein a valve ball loading port is formed in the upper end of a valve cavity of the valve body, a valve ball is arranged inside the valve cavity, a first inclined plane combined type valve base is arranged at the left end of the valve ball, and a second inclined plane combined valve base is arranged at the right end of the valve ball; a positioning boss is arranged at the upper end of the valve ball, a positioning groove is vertically formed in the middle of the positioning boss, a sliding block is arranged on the positioning boss, a positioning lug is integrally arranged on the lower end surface of the sliding block, and the positioning lug is inserted into the positioning groove; a spring groove is vertically formed in the middle of the upper end surface of the sliding block, a spring assembly is arranged inside the spring groove in a embedded mode, a valve rod is arranged right above the spring assembly, and a valve cover is arranged on the valve rod in a sleeved mode. According to the technical scheme, the structure design is reasonable, the structure is simple, the high-safety die forging ball valve is not easy to leakage, the sealing performance is good, the valve rod is not easy to bend or deform, the valve opening and closing torque is small, the maintenance is convenient, the service life is long, the work is stable, and the practicability is good.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a high-safety forging ball valve. Background technique [0002] Floating ball valve is a fluid control product with a large quantity and a wide range, which is widely used in various pipeline systems. However, most of the existing ball valves are made of two-piece castings or forgings, and there are many leakage points, many casting defects, pores or trachoma, and the preload pressure of the valve seat is not easy to control; and the ball of the existing ball valve is under the action of the fluid medium. It will be pushed to the outlet side, which will generate a driving force on the bottom of the valve stem, which will easily cause the valve stem to bend and deform. The service life is short and frequent maintenance is required, but the maintenance operation is difficult, inconvenient to use, and poor in practicability. Contents of the invention [0003] In view of the defic...
