Utility model content:
The purpose of this utility model is to provide a kind of structure simple, easy for installation and can at the deck safety protective device of the tank truck effectively protecting tank body to be vented.
For achieving the above object, the utility model adopts following technical scheme to be achieved:
A kind of deck safety protective device of tank truck, comprise upper shell, lift stopper, bolt and nut, wherein, be flexibly connected from top to bottom between upper shell with lift stopper, the center of upper shell offers through hole, bolt is arranged in this through hole, and one end of bolt is fixedly connected with the center of lift stopper, and nut is arranged on the other end of bolt; The side of lift stopper offers stepped hole, spring and valve block is provided with in stepped hole, one end of spring is connected with the bottom of stepped hole, its other end connects valve block, the opposite side of lift stopper offers second exhaust port, side corresponding with second exhaust port on upper shell offers first row gas port, and first row gas port and second exhaust port are in shifting to install; During use, the bottom of upper shell is arranged on the tank deck of tank truck.
The utility model further improves and is: be provided with the packing ring for sealing bottom upper shell and between the tank deck of tank truck.
The utility model further improves and is: during use, and spring is in compressive state.
The utility model further improves and is: nut is hexagonal (hexagon)nut.
The utility model further improves and is: the quantity of nut is 2.
The utility model further improves and is: first row gas port and second exhaust port are respectively provided with two.
The utility model further improves and is: valve block is shape ringwise.
Compared with prior art, the beneficial effects of the utility model are: the deck safety protective device of this tank truck, by the lift stopper that is provided with and valve block can be stable control tank body in gas discharging stablize, holding structure safety, bolt can control the size of free air capacity easily, and first row gas port and second exhaust port can keep producing Leakage Gas in shifting to install.Further, packing ring can keep air-tightness when installing.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the deck safety protective device of a kind of tank truck of the utility model.
In figure: 1 is upper shell, 2 is lift stopper, and 3 is bolt, and 4 is nut, and 5 is spring, and 6 is valve block, and 7 is first row gas port, and 8 is second exhaust port, and 9 is packing ring.
