Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
Referring to fig. 1, the automatic closing device for the subsea valve of the oil vehicle comprises a main vehicle power switch Y, an electromagnetic pneumatic control valve D, a hand-operated valve S, a pneumatic control subsea valve H, a pneumatic control valve Q, a quick release valve K, a dual-cavity brake air chamber A and an air storage cylinder C, wherein one outlet end of the air storage cylinder C is connected with one end of the electromagnetic pneumatic control valve D through the hand-operated valve S, the other end of the electromagnetic pneumatic control valve D is connected with the pneumatic control subsea valve H and a first end of the pneumatic control valve Q, a second end of the pneumatic control valve Q is connected with the other outlet end of the air storage cylinder C, a third end of the pneumatic control valve Q is connected with an input end of the quick release valve K, an output end of the quick release valve K is respectively connected with two cavities A1/A2 of the dual-cavity brake air chamber A. The electromagnetic pneumatic control valve D is an electromagnetic valve with an air path closed when power is on and an air path communicated when power is off. The normal state of the pneumatic control valve Q is that the second end of the pneumatic control valve Q is communicated with the third end of the pneumatic control valve Q, and the second end and the third end of the pneumatic control valve Q are in a closed state when air pressure enters the first end of the pneumatic control valve Q.
When the power switch Y of the main vehicle is turned on during operation, the electromagnetic pneumatic control valve D is electrified and turned on, the gas circuit between the hand-pull valve S and the subsea valve H and between the hand-pull valve S and the pneumatic control valve Q is closed, and the gas circuit of the hand-pull valve S is opened and is not communicated at the moment, so that the subsea valve H cannot be opened for unloading; when a power switch Y of the main vehicle is closed, the electromagnetic pneumatic control valve D is powered off and closed, an air path between the hand power valve S and the sea bottom valve H and between the hand power valve S and the pneumatic control valve Q is opened, compressed air in an air storage cylinder C of the hand power valve S is opened at the moment, the sea bottom valve H is opened through the air path, the connection between the quick release valve K and the air storage cylinder C is cut off through the pneumatic control valve Q, the quick release valve K is opened to enable the compressed air in a double-cavity brake air chamber A1 and a rear cavity air chamber A2 to exhaust the vehicle brake, and oil unloading can; when oil unloading is completed and the hand-operated valve S is forgotten to be closed, the sea bottom valve H is not closed, the double-cavity brake air chamber A1 and A2 continue to brake, when a power switch Y of the main vehicle is opened, the electromagnetic pneumatic control valve D is electrified and opened, an air path between the hand-operated valve S and the sea bottom valve H and between the hand-operated valve S and the pneumatic control valve Q is closed, compressed air in the air path of the sea bottom valve H cylinder and the pneumatic control valve Q is discharged through the electromagnetic pneumatic control valve, the sea bottom valve H is closed, the pneumatic control valve Q is disconnected, the quick release valve K is communicated with the air storage cylinder C again, the quick release valve K is closed, the double-cavity brake air chamber A1 is used, and compressed air enters the.
The utility model relates to a rationally, simple structure, the practicality is strong. After the utility model is adopted, oil can be discharged only when the main vehicle is powered off, and the vehicle can automatically brake when discharging oil; when the driver forgets to close the subsea valve after oil unloading, the vehicle power-on system automatically closes the subsea valve and releases oil unloading brake, so that the safety during operation is improved, and safety accidents caused by manual misoperation are reduced.
