Utility model content
The purpose of this utility model is to provide a kind of tank car sea cock and valve automatic control system, solves existing tank car sea cock and valve and can not realize remote auto control and not have the problem of state-detection and Presentation Function.
The technical scheme that the utility model adopts is, a kind of tank car sea cock and valve automatic control system, comprise master control hand valve, the air intake opening of master control hand valve is connected with tank car gas-holder, the gas outlet of master control hand valve is connected with solenoid valve, the air intake opening switching hand valve and tank car petroleum vapor recovery valve respectively, the gas outlet switching hand valve is connected with pressure switch, and pressure switch is also connected with tank car sea cock and valve; Control module is connected with the output contact of solenoid valve and pressure switch respectively by wire.
Feature of the present utility model is also,
The air intake opening switching hand valve is connected with tank body petroleum vapor recovery valve, and the gas outlet switching hand valve is connected with tank body sea cock and valve.
Pressure switch is PS11 Series Pressure switch.
Control module comprises microprocessor and display screen.
Microprocessor is embedded microprocessor, and its model is AT91ARM microprocessor.
Display screen is LED display.
The beneficial effects of the utility model are, the utility model, on the basis of Non-follow control, installs solenoid valve and pressure switch additional, and utilize control module to achieve the automatic control of sea cock and valve; Control module can show the opening and closing shape of tank car sea cock and valve simultaneously, reaches the object detected in real time.

In figure, 1. master control hand valve, 2. gas-holder, 3. solenoid valve, 4. switches hand valve, 5. petroleum vapor recovery valve, 6. pressure switch, 7. sea cock and valve, 8. control module.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of tank car sea cock and valve of the utility model automatic control system, comprise master control hand valve 1, the air intake opening of master control hand valve 1 is connected with tank car gas-holder 2, the gas outlet of master control hand valve 1 is connected with solenoid valve 3, the air intake opening switching hand valve 4 and tank car petroleum vapor recovery valve 5 respectively, the gas outlet switching hand valve 4 is connected with pressure switch 6, and pressure switch 6 is also connected with tank car sea cock and valve 7; Control module 8 is connected with the output contact of solenoid valve 3 and pressure switch 6 respectively by wire.
Wherein, the air intake opening switching hand valve 4 is connected with tank body petroleum vapor recovery valve 5, and the gas outlet switching hand valve 4 is connected with tank body sea cock and valve 7.Pressure switch 6 is PS11 Series Pressure switch.Control module 8 comprises microprocessor and display screen.Microprocessor is embedded microprocessor, and its model is AT91ARM microprocessor, and display screen is LED display.
The utility model system comprises automatically and manual mode, and the control procedure of automatic mode is:
Open master control hand valve 1, high pressure gas flows to the air intake opening of solenoid valve 3 by master control hand valve 1 from gas-holder 2, because the air intake opening of petroleum vapor recovery valve 5 with solenoid valve 3 is connected, therefore petroleum vapor recovery valve 5 is opened, for petroleum vapor recovery has carried out Job readiness; Now, control module 8 sends to solenoid valve 3 and opens control signal, and solenoid valve 3 is opened, and high pressure gas flows to from the gas outlet of solenoid valve 3 a mouth switching hand valve 4, and the c mouth again through switching hand valve 4 flows to tank car sea cock and valve 7, and sea cock and valve 7 is opened.At this moment, the process to tank car handling liquid just can start; Finally, after handling liquid process terminates, control module 8 sends closing control signal to solenoid valve 3, and solenoid valve 3 cuts out.High pressure gas in sea cock and valve 7 is discharged through solenoid valve 3 exhausr port, and sea cock and valve 7 is closed.At this moment, tank car can start transportation, and its constitutional diagram as shown in Figure 1.
When circuit breaks down, MANUAL CONTROL mode is opened, and its course of work is: open master control hand valve 1, the gas outlet of master control hand valve 1 is connected with petroleum vapor recovery valve 5, and therefore petroleum vapor recovery valve 5 is opened, for petroleum vapor recovery has carried out Job readiness; The gas outlet of master control hand valve 1 also with the b mouth switching hand valve 4, high pressure gas flows to the b mouth switching hand valve 4 by master control hand valve 1 from gas-holder 2, then flow to tank car sea cock and valve 7 by c mouth, sea cock and valve 7 is opened, process to tank car handling liquid just can start, and Fig. 2 is shown in its constitutional diagram.
Tank car sea cock and valve state-detection with procedure for displaying is: the air intake opening of pressure switch 6 is connected with tank car sea cock and valve 7, tank car sea cock and valve 7 open and-shut mode detected, and give control module 8 by its contact signal according to the large I of pressure.Display screen display tank car sea cock and valve 7 in control module 8 closes shape, so as staff to carry out handling accordingly fluid operated.
