Abstract
The utility model relates to the technical field of valves, in particular to a novel valve which is characterized by comprising a valve body, a valve cover, a ball, a left seal, valve stem packing, a valve stem sleeve, a lower seal, a valve stem and a right seal. The left seal is arranged at the left upper end of the valve stem, so that the valve stem is protected from corrosion fracture.
Description
Technical field
The utility model relates to valve technology field, especially a kind of ball valve.
Background technique
Traditional ball valve 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 ball valve; described a kind of ball valve; it is characterized in that; comprise: valve body 1, valve gap 2, spheroid 3, left sealing 4, stem packing 5, valve stem casing 6, lower seal 7, valve rod 8, right sealing 9, described a kind of ball valve is provided with left sealing 4 at the left upper end of valve rod 8; described left sealing 4 is arranged on the left side of valve rod 8, and protection valve rod 8 has been avoided the valve rod corrosion fracture.
The utility model beneficial effect is: avoid valve stem crack 1.; 2. reach energy-saving effect without leakage.
Description of drawings
Fig. 1 is the utility model structural representation
Wherein: valve body 1, valve gap 2, spheroid 3, left sealing 4, stem packing 5, valve stem casing 6, lower seal 7, valve rod 8, right sealing 9.
Embodiment
As shown in Figure 1, described a kind of ball valve is provided with left sealing 4 at the left upper end of valve rod 8, and described left sealing 4 is arranged on the left side of valve rod 8, and protection valve rod 8 has been avoided the valve rod corrosion fracture.
