Abstract
The utility model relates to the technical field of valves, in particular to a novel breakage preventing vacuum ball valve. The novel breakage preventing vacuum ball valve is characterized by comprising a valve body, a ball body, an upper valve seat, valve rod asbestos, padding, a valve rod, a valve rod core, and a vacuum chamber. According to the novel breakage preventing vacuum ball valve, the vacuum chamber is arranged on the valve rod so as to prevent the valve from being corroded and leaking.
Description
Technical field

Background technique
Traditional ball valve is under the low temperature of cryogenic 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 anti-fracture Vacuum ball valve, described a kind of Novel anti-fracture Vacuum ball valve, it is characterized in that, comprise: valve body 1, spheroid 2, upper valve base 3, valve rod asbestos 4, filler 5, valve rod 6, valve rod core 7, vacuum chamber 8, described a kind of Novel anti-fracture Vacuum ball valve is provided with vacuum chamber 8 at valve rod 6, avoids the valve corrosion leakage.
The utility model beneficial effect is: 1. without leaking; 2. avoid corrosion to reach energy-saving effect.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: valve body 1, spheroid 2, upper valve base 3, valve rod asbestos 4, filler 5, valve rod 6, valve rod core 7, vacuum chamber 8.
Embodiment
As shown in Figure 1, described a kind of Novel anti-fracture Vacuum ball valve is provided with vacuum chamber 8 at valve rod 6, avoids the valve corrosion leakage.
