Abstract
The utility model relates to the technical field of a valve, in particular to a novel pressure sealing ball valve. The novel high pressure sealing ball valve is characterized by comprising a valve body, a right sealing chamber, a ball body, a left sealing chamber, valve padding, a valve rod sleeve, a lower sealing and a vale rod. According to the novel high pressure sealing ball valve, the right sealing chamber is arranged on the valve rod to prevent the valve rod from being broken under high pressure.
Description
Technical field
The utility model relates to valve technology field, especially a kind of novel high-pressure seal ball-valve.
Background technique
The ball valve of system is under the high temperature of High Temperature High Pressure and long-term corrosion, and valve rod ruptures easily, and rubber seal is leaked easily, and valve was lost efficacy easily.
Summary of the invention
For addressing the above problem; the utility model provides a kind of novel high-pressure seal ball-valve; described a kind of novel high-pressure seal ball-valve; it is characterized in that; comprise: valve body 1, right closed chamber 2, spheroid 3, left closed chamber 4, stem packing 5, valve stem casing 6, lower seal 7, valve rod 8; described a kind of novel high-pressure seal ball-valve is provided with right closed chamber 2 at valve rod 8, and protection valve rod 8 has been avoided the fracture of valve rod high pressure.
The utility model beneficial effect: 1. avoid valve stem crack; 2. reach energy-saving effect without leakage.
