Description

Emergency cut-off valve switch alarm device for tank type transport vehicle

Technical Field

The utility model relates to a tank transportation vehicle emergency cut-off valve switch, specifically speaking relate to a tank transportation vehicle emergency cut-off valve switch alarm device.

Background

The goods that the liquid dangerous cargo transport vehicle of tank formula transported leaks to have certain harm nature under all kinds of accident situation appear, according to the national regulation, for preventing that the liquid dangerous cargo transport vehicle of tank formula from appearing leaking in the emergence accident in-process, at jar body lower part installation quick emergency valve, pneumatic combination switch's air supply interface even has the gas receiver through the pipeline that admits air, pneumatic combination switch hand switch's air supply interface passes through the air supply line and links to each other with the interface that admits air of quick emergency valve. The emergency cut-off valve automatically cuts off when the vehicle is subjected to strong impact and high temperature, and blocks the impact of external force on the tank body to prevent goods in the tank body from leaking.

The leakage condition of accidents is effectively avoided after the emergency stop valve is arranged on the vehicle, but the condition of cargo leakage can also be caused if an operator forgets to close the emergency stop valve before the vehicle goes into a bus due to carelessness of work.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a can self-closing emergency cut-off valve when the driving to can not lead to forgetting to close the emergency cut-off valve because of staff negligence and cause the tank transportation vehicle emergency cut-off valve switch alarm device that the goods leaked.

In order to solve the technical problem, the utility model relates to an emergency cut-off valve switch alarm device for tank transport vehicles, wherein the tank transport vehicles comprise a vehicle chassis and an oil tank arranged on the vehicle chassis, a plurality of emergency cut-off valves are respectively arranged at the bottom of the oil tank, an air source interface of a pneumatic combination switch is connected with an air storage cylinder through an air inlet pipeline, air supply interfaces of a plurality of manual switches of the pneumatic combination switch are respectively connected with the air inlet interfaces of the emergency cut-off valves through air supply pipelines, a three-way pipe fitting is also arranged on the air inlet pipeline, a two-position three-way electromagnetic valve is arranged between the three-way pipe fitting and a main switch of the pneumatic combination switch, the alarm device also comprises a pressure switch, a pressure switch controller and a vehicle displacement signal receiver, a signal input end of the pressure switch is connected with the main switch of the pneumatic combination switch, the signal output end of the vehicle displacement signal receiver is also connected with the signal input end of the pressure switch controller, the signal input end of the two-position three-way electromagnetic valve is connected with the signal output end of the pressure switch controller, and the pressure switch controller is also connected with an audible and visual alarm.

Adopt the quick-witted switch alarm device of tank transportation vehicle emergency cut-off valve of above-mentioned structure, the accessible is in predetermine the pressure value in the pressure switch controller and be 0.6MPa, when the pressure switch controller received the pressure signal of pressure switch conveying be greater than 0.6MPa, and received vehicle displacement signal receiver conveying and control pressure switch and close when having the displacement to produce, two three way solenoid valve discharges simultaneously gas in the pneumatic combination switch, thereby close the quick-cut valve emergency cut-off valve, prevent that the vehicle from forgetting to close and cause the phenomenon of goods leakage because of staff negligence emergency cut-off valve when traveling.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural composition diagram of the emergency cut-off valve switch alarm device of the tank type transport vehicle.

Detailed Description

Referring to fig. 1, the utility model relates to a tank transportation vehicle emergency cut-off valve switch alarm device, tank transportation vehicle includes vehicle chassis 1 and adorns the oil tank 2 on vehicle chassis, and a plurality of emergency cut-off valves 3 are adorned respectively in the bottom of oil tank, and pneumatic combination switch 4's air supply interface even has an air receiver 6 through air inlet pipe line 5, and pneumatic combination switch 4 a plurality of manual switch 41's air supply interface respectively through air supply line 7 with the air inlet interface of a plurality of emergency cut-off valves 3 links to each other, still be equipped with tee bend pipe fitting 8 on the air inlet pipe line 5, be equipped with two-position three way solenoid valve 9 through the pipeline between tee bend pipe fitting 8 and pneumatic combination switch 4's the master switch 42, still include pressure switch 10, pressure switch controller 11 and vehicle displacement signal receiver 12, this vehicle displacement signal receiver can be GPS big dipper dual mode antenna, the signal input part of pressure switch 10 with pneumatic combination switch 4's master, The signal output end is connected with the signal input end of the pressure switch controller 11, the signal output end of the vehicle displacement signal receiver 12 is also connected with the signal input end of the pressure switch controller 11, the signal input end of the two-position three-way electromagnetic valve 9 is connected with the signal output end of the pressure switch controller 11, and the pressure switch controller 11 is further connected with an audible and visual alarm 13.

The utility model discloses in, pressure switch controller 11 can be PLC, PLC receives simultaneously the displacement signal of the pressure signal of pressure switch 10 conveying and the displacement signal of vehicle displacement signal receiver 12 conveying, produce the displacement and PLC control pressure switch closes when the pressure value is greater than 0.6MPa when the vehicle, thereby close the quick action emergency valve 3 of 2 bottoms of oil tank avoids leading to the quick action emergency valve to forget to close the trouble that causes the goods to leak because of the human negligence when the vehicle goes, and pressure switch controller 11 still even has audible-visual annunciator 13, can remind field operation personnel through audible-visual annunciator simultaneously. The vehicle is in a running state due to the displacement of the vehicle, and the pressure value transmitted by the pressure switch is greater than 0.6MPa, so that the emergency cut-off valve is in an open state.
