Abstract
The utility model relates to the technical field of valves, in particular to a novel heatproof butterfly valve which is characterized by comprising a stem, a seal, a valve plate pin, a valve plate seal, a valve plate, a valve block and a plate pin seal. The seal is arranged at the upper end of the stem of the novel heatproof butterfly valve and is made of graphite filler, so that heating of the stem is prevented and breakage of the stem is prevented.
Description
Technical field
The utility model relates to valve technology field, especially a kind of novel solar heat protection butterfly valve.
Background technique
Traditional butterfly valve plate is to be enclosed within the middle of the valve rod, and when pipeline heat and pressure were large, the fracture that just disconnects easily of valve plate and valve rod caused valve to lose efficacy easily.
Summary of the invention
For addressing the above problem, the utility model provides a kind of novel solar heat protection butterfly valve, described a kind of novel solar heat protection butterfly valve, it is characterized in that, comprising: valve rod 1, sealing 2, valve plate pin 3, valve plate sealing 4, valve plate 5, plate pin sealing 6, valve body 7, described a kind of novel solar heat protection butterfly valve, be provided with sealing 2 in valve rod 1 upper end, described sealing 2 is to use graphite as filler, prevents valve rod 1 heating, has avoided valve rod 1 fracture.
The beneficial effects of the utility model are: 1. relief valve heat and pressure, strengthen anticorrosion effect; 2. avoided the shortcoming of valve fracture failure; 3. save material and reach energy-saving effect.
Description of drawings
Fig. 1 is the utility model structural representation
Wherein: valve rod 1, sealing 2, valve plate pin 3, valve plate sealing 4, valve plate 5, plate pin sealing 6, valve body 7.
Embodiment
Shown in Figure 1, described a kind of novel solar heat protection butterfly valve is provided with sealing 2 in valve rod 1 upper end, and described sealing 2 is to use graphite as filler, prevents valve rod 1 heating, has avoided valve rod 1 fracture.
Claims (1)
