Background technique
At present, traditional tank car tank case bottom discharge valve is ball valve, and the life-span is short, open dumb and do not possess emergency cut-off function.The liquid hazardous goods vehicle rapid growth of road transport, this vehicle Annual output is high, recoverable amount is large, and safety, the environmental accident such as transporting cargo blast, leakage that cause because of road traffic accident of such vehicle is very many every year.When having an accident, the accident that such vehicle causes dangerous chemical leakage because the discharging ball valve previously installed lost efficacy and causes is of common occurrence.Nowadays, domestic special sound for road transport liquid hazardous goods vehicle standard, such vehicle bottom discharge valve need possess emergency cut-off function.
Although, the road liquid transporting vehicle of new research and development is equipped with special valve at present, but for the vehicle produced or use, if reequip, then not only cost is high, and reduces its Security, in addition, repacking is longer for man-hour, and the not easy care of the vehicle after repacking, what have even scraps process owing to not reequiping.
Model utility content
For the deficiency existing for prior art; the utility model provide a kind of can the tank car bottom discharge foot valve of emergency cut-off; this foot valve safety coefficient is high, cost is low; and with emergency cut-off structure; in discharge process; can open flexibly or close; when having an accident; valve is subject to greater impact power; valve body part will be cut off automatically, and release impact energy, is not damaged to protect tank body; the sealing mechanism of valve self is not subject to any damage simultaneously, and to ensure, the security incident leaked and cause does not occur transporting cargo.
The utility model can the technological scheme that is achieved of the tank car bottom discharge foot valve of emergency cut-off be: this foot valve comprises valve body, spool, spool top laminated structure, spool opening structure and valve bonnet seal assembly; Described valve body comprises valve body pipe, one end of described valve body pipe is provided with outlet(discharge) flange, the other end of described valve body pipe is provided with inlet flange, described spool top laminated structure comprises a cage spring fixing frame, be sleeved on spool upward pressure spring and be located at the spring anchorage bracket supporting post of inlet flange side of described valve body, described pressure spring one end withstands on cage spring fixing frame, and the other end withstands on spool; Described spool opening structure comprises valve rod, crank and push rod, and described spool is provided with a pyramidal pits towards the surface of valve pocket, and the center line of described valve body pipe, outlet(discharge) flange and inlet flange is on same straight line; The external rotary surface of described valve body pipe is provided with a circle shear groove with the joint of described inlet flange.
The utility model can the tank car bottom discharge foot valve of emergency cut-off, and the relatively described spool of described pyramidal pits is coaxial or eccentric setting.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can ensure the liquid hazardous goods vehicle of road transport emergency cut-off valve when having an accident, and prevents dangerous liquid from revealing; More change bottom discharge ball valve, highly versatile for production or the vehicle in using.
