Abstract
The utility model relates to the technical field of valves, in particular to a novel low-temperature valve which is characterized by comprising a valve body, a ball, an upper valve base, a valve rod sleeve, valve rod packing, a packing chamber, a valve rod, a lower valve base and a valve base. According to the novel low-temperature valve, the upper valve base is arranged on the valve body, a gap is arranged between the upper valve base and the ball, and therefore valve corrosion and leakage are avoided.
Description
Technical field
The utility model relates to valve technology field, especially a kind of new type low temperature valve.
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 new type low temperature valve, described a kind of new type low temperature valve, it is characterized in that, comprise: valve body 1, spheroid 2, upper valve base 3, valve stem casing 4, stem packing 5, filler chamber 6, valve rod 7, lower valve base 8, valve seat 9, described a kind of new type low temperature valve is provided with upper valve base 3 at valve body 1, described upper valve base 3 is provided with the gap with spheroid 2, 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 stem casing 4, stem packing 5, filler chamber 6, valve rod 7, lower valve base 8, valve seat 9.
Embodiment
As shown in Figure 1, described a kind of new type low temperature valve is provided with upper valve base 3 at valve body 1, and described upper valve base 3 is provided with the gap with spheroid 2, avoids the valve corrosion leakage.
