Embodiment 1

[0061] The invention provides a linkage control system for monitoring the opening and closing state of the emergency shut-off valve of the tank truck. The linkage control system can monitor the opening and closing state of the emergency shut-off valve during the transportation of the tank truck, The emergency shut-off valve can be automatically closed when the accident occurs, thereby fundamentally avoiding the occurrence of accidents. The schematic diagram of the linkage control system is as follows: image 3 as shown,

[0062] The linkage control system includes an emergency shut-off valve 1 , a control unit 2 , an electromagnetic valve 3 , an alarm unit 4 , and a sensing unit 5 .

[0063] The first input port of the control unit 2 is connected to the sensing unit 5, and the second input port is connected to the emergency shut-off valve 1; the first output port of the control unit 2 is connected to the control port of the electromagnetic valve 3, and the second output port ...

Embodiment 2

[0089] Embodiment 2 provides another linkage control system for monitoring the opening and closing state of the emergency shut-off valve of the tank truck. It is the same as Embodiment 1, and still includes an emergency shut-off valve 1, a control unit 2, an electromagnetic valve 3, an alarm unit 4, Sensing unit 5. The emergency shut-off valve 1 includes: a valve body 101, a valve cover 102, a valve core 103, a compression spring 104, a cylinder 105, a piston 106, a detection module 107, a fuse bolt 108, a gas joint 109, a push rod 110 and a guide rod 111. The sensing unit 5 is a vehicle speed sensor. The alarm unit 4 is a voice alarm or an audible and visual alarm.

[0090] The difference between the second embodiment and the first embodiment is that the detection module 107 in the emergency shut-off valve 1 is a proximity switch, which can detect the position information of the piston bottom of the emergency shut-off valve 1 . The workflow of the control unit 2 is as follo...

Abstract

The invention relates to a linkage control system and method for monitoring opening and closing states of an emergency shut-off valve. An emergency shut-off valve (1) is internally provided with a detection module (107) for detecting opening and closing states of the emergency shut-off valve (1); the first input port of a control unit (2) is connected with a sensing unit (5), and the second inputport is connected with the detection module (107) of the emergency shut-off valve (1); the first output port of the control unit (2) is connected with the control end of an electropneumatic valve (3),and the second output port is connected with an alarm unit (4); the air inlet end of the electropneumatic valve (3) is connected with an air source, and the air outlet end is connected with the air connector of the emergency shut-off valve. According to the linkage control system and method provided by the invention, the detection module in the emergency shut-off valve can be used for monitoringthe opening and closing states of the emergency shut-off valve in real time and make a judgment, and by control the opening and closing of the emergency shut-off valve through a control system program, the purposes of monitoring the opening and closing states of the emergency shut-off valve while automatically controlling the opening and closing of the emergency shut-off valve are realized.

Description

technical field [0001] The invention relates to the field of emergency shut-off valve opening detection equipment, in particular to a linkage control system and method for monitoring the opening and closing state of an emergency shut-off valve. Background technique [0002] Oil tank trucks are extremely dangerous during transportation. Therefore, according to national standards, emergency shut-off valves must be installed on dangerous goods transport vehicles. The emergency shut-off valve, commonly known as the submarine valve, can cut off the pipeline system connected to the tank in the event of an accident to prevent the leakage of dangerous goods and expand the danger level of the accident. [0003] The emergency shut-off valve is usually installed at the bottom of the tank body of the tank truck, and it is the main valve in the oil pipeline, which is used to control the flow of oil in the oil pipeline. During transportation, the emergency shut-off valve must be closed t...
