Description
Technical field
The utility model relates to a kind of emergency cut-off system of tank container, particularly a kind of emergency cut-off system of tank container, and it utilizes gas in the tank container tank body as the source of the gas of the Emergeny Cutoff Valves of tank container.
Background technique
At present, the tank container that is used for danger medium such as conveying liquified gas or cryogenic liquide is more, the root of its main liquid phase, gas phase pipeline is provided with emergency shutoff device usually, so that at pipeline and annex breaks or block the liquid in-out pipeline rapidly during urgency such as misoperation or the breaking out of fire of tank car annex, avoid the state of affairs further to enlarge.Emergency shutoff device commonly used has gas control, the oil control or cable control.Because shipping container and semitrailer underframe are relatively independent, throw off through regular meeting and underframe, therefore can't use the brake source of the gas of semitrailer easily.Generally need that air pump is installed in addition or oil pump provides power source, its structure is very complicated.If adopt cable control, though its structure is simple, command range is very short, when urgency, may since can't near and can not in time cut off pipeline.
Summary of the invention
In view of above-mentioned shortcoming, the purpose of this utility model is to provide a kind of emergency cut-off valve system that can simplify shipping container, and can realize the Emergeny Cutoff Valves of remote-operated tank container easily.
In order to achieve the above object, the utility model provides a kind of emergency cut-off system of tank container, the operating box that this tank container comprises tank body and is arranged on this tank body rear portion, wherein this emergency cut-off system comprises: the root stop valve, it is arranged in this operating box, communicate with the gas phase pipe of this tank body, when non-loading and unloading medium (comprising in the transportation process) close, only open when unloading liquid filling; Emergency control valve, it has suction port, air outlet and drain, and this suction port is communicated with this root stop valve; And Emergeny Cutoff Valves, it is arranged in this operating box, be installed in the main gas phase pipe of this tank body and/or the root of liquid-phase tube, and be communicated with the air outlet of this emergency control valve, this Emergeny Cutoff Valves top is provided with pneumatic head, to open as the control source of the gas by the gas in the tank body of this root stop valve and this emergency control valve, and liquid-phase tube and/or gas phase pipe are communicated with, and when in filling process urgency taking place, drain by this emergency control valve is closed the gas emptying in the pneumatic head of Emergeny Cutoff Valves with Emergeny Cutoff Valves, to cut off the connection of liquid-phase tube and/or gas phase pipe, spread expansion to avoid the state of affairs.
According to tank container emergency cut-off of the present utility model system, wherein this emergency control valve is set in place in the minor valve case of this operating box front portion.
The emergency cut-off system of tank container of the present utility model adopts tank container self gas as the Emergeny Cutoff Valves source of the gas, therefore the emergency cut-off valve system of shipping container can be simplified, and the Emergeny Cutoff Valves of remote-operated tank container can be realized easily.
Description of drawings
Fig. 1 shows the plan view that has the tank container of emergency cut-off system according to of the present invention.
Wherein, description of reference numerals is as follows:
1 tank container, 2 tank bodies, 3 operating boxs, 4 root stop valves
5 emergency control valves, 51 suction ports, 52 air outlets, 53 drains
6 Emergeny Cutoff Valvess, 7 minor valve casees
Embodiment
Describe according to the tank container with emergency cut-off system of the present utility model below with reference to Fig. 1.As shown in the figure, because the gas-phase space that the inside of the tank body 2 of the tank container 1 of conveying liquified gas or cryogenic liquide has a constant volume, wherein be full of compressed gas, therefore can be directly from the gas phase Guan Yinyi root tubule of tank body 2 so that this compressed gas is caused root stop valve 4, and then this pipe drawn from operating box 3, and extend to the emergency control valve 5 of the minor valve case 7 that is positioned at operating box 3 front portions, the pneumatic head that feeds Emergeny Cutoff Valves 6 again is as the control source of the gas, this Emergeny Cutoff Valves 6 is installed in the root of gas phase pipe and/or liquid-phase tube, and be not limited to 1, can be for a plurality of, promptly 1 emergency control valve can be controlled a plurality of Emergeny Cutoff Valvess, certainly the position of this emergency control valve 5 also is not limited thereto, what it can be arranged on tank container 1 is convenient in case of emergency that personnel are easy to arrive on any position of controlling, this Emergeny Cutoff Valves 5 is used to control the connection of liquid-phase tube and/or gas phase pipe and cut out, and this emergency control valve 5 has a suction port 51, an air outlet 52 and a drain 53.Compressed gas is drawn in the pneumatic head of getting back to the Emergeny Cutoff Valves 6 that fills the pipe (not shown) in the operating box 3 once more by emergency control valve 5.This emergency control valve 5 can be manual three-way valve.
Generally (in transportation process), root stop valve 4 is closed, and no gas in the pneumatic head of Emergeny Cutoff Valves 5 is in closed condition.When tank container 1 fills when unloading liquid, root stop valve 4 is opened, at this moment the suction port 51 of the emergency control valve 5 of the front portion of operating box 3 is communicated with air outlet 52, gas in the tank body 2 enters in the pneumatic head of Emergeny Cutoff Valves 6 by this suction port 51 and this air outlet 52 under pressure, thereby open Emergeny Cutoff Valves 6, shipping container can be communicated with the work of unloading of filling normally with liquid-phase tube and/or gas phase pipe by Emergeny Cutoff Valves 6 like this.When filling the work of unloading when finishing, close root stop valve 4, rotate the handle of emergency control valve 5 then or push the knob of emergency control valve 5, so that air outlet 52 is connected with drain 53, but the gas in the pneumatic head of emptying Emergeny Cutoff Valves 6 like this, close Emergeny Cutoff Valves 6, thereby cut off the connection of liquid-phase tube and/or gas phase pipe.If urgency takes place in filling the process of unloading, can in time pass through the emergency control valve 5 of the front portion of manipulation tank container 1, make its air outlet 51 and drain 53 connect and Emergeny Cutoff Valves 6 cuts out, avoid the state of affairs further to enlarge.
Compare with conventional art, the advantage of the emergency cut-off system of tank container of the present utility model is: the emergency cut-off system of tank container of the present utility model adopts tank container self gas as the Emergeny Cutoff Valves source of the gas, greatly simplified emergency shutoff device, shipping container can be thrown off with the semitrailer underframe easily, and can realize telecontrol, also reduce the manufacturing process and the cost of shipping container on the other hand.
