Abstract
The utility model discloses a kind of natural gas storage tank peculiar to vessel being provided with flameproof apparatus, belong to storage tank manufacturing technology field.Be filled with thermoinsulation material in insulating sandwich, coordinate vacuum effectiveness, improve heat-insulating property further.When rising to a certain degree atmospherically in insulating sandwich, Explosion-proof cap will be rushed to open, and just can prevent enclosure air pressure from continuing to rise.Safety cover can prevent Explosion-proof cap to be rushed to open backward outer to fly, and causes damage to personnel equipment.Elastic component can play the dual functions flown Explosion-proof cap pressurization and obstruction Explosion-proof cap.
Description
Technical field
The utility model relates to a kind of natural gas storage tank peculiar to vessel being provided with flameproof apparatus, belongs to storage tank manufacturing technology field.
Background technique
This novel energy of rock gas has clean, environmental protection, efficiently feature compared with other primary energy, will by natural gas transportation to making land used, generally pipeline transport can be adopted, or the traffic tool, as fuel tank, ship etc. transport, if rock gas is transported by country over strait, be just merely able to be transported by ship.Rock gas is mainly based on methane, methane is a kind of gas, conveniently store transport, usually methane liquefaction is become liquid, like this, storage tank needs the state remaining on a cryogenic high pressure, therefore, insulating sandwich can be provided with in storage tank, thermal-protective material is filled with in insulating sandwich, but, if internal layer leaks, but because skin does not leak, rock gas is just filled with insulating sandwich, the pressure of insulating sandwich is caused to be greater than the pressure of ambient atmosphere, skin is likely broken through, there is security incident, serious, if storage tank collides or runs into naked light and more to blast accident in transportation process, consequence is hardly imaginable.
Model utility content
For solving the problem, the utility model provides a kind of structure simple, the natural gas storage tank peculiar to vessel being provided with flameproof apparatus of use safety.
The technological scheme that the utility model adopts for its problem of solution is:
Be provided with a natural gas storage tank peculiar to vessel for flameproof apparatus, comprise inner casing and shell, between described inner casing and shell, be provided with the insulating sandwich of filling heat insulator; Be plugged with vacuum-pumping tube in described insulating sandwich, one end of described vacuum-pumping tube is positioned at insulating sandwich, and the other end is positioned at housing exterior; Described shell is provided with ventilating hole and breathing pipe, described breathing pipe one end is plugged on described ventilating hole, and the other end is covered with Explosion-proof cap, and described Explosion-proof cap and breathing pipe madial wall are interference fit; Described flameproof apparatus also comprises one and covers on breathing pipe, for preventing Explosion-proof cap from flicking safety cover; Elastic component is provided with between described safety cover and Explosion-proof cap.
Preferably, the bottom of described safety cover is fixed on shell or on breathing pipe.
Preferably, the leak-proof gasket preventing natural gas leaking is provided with between described breathing pipe and the surface of contact of Explosion-proof cap.
Preferably, described elastic component is spring, and elastic component internal sleeve is provided with a threaded stem; one end of described threaded stem is fixed on described safety cover; the other end screw thread is provided with an adjusting nut, and one end of described elastic component is connected on Explosion-proof cap, and the other end is connected on described adjusting nut.
The beneficial effects of the utility model are: be filled with thermoinsulation material in insulating sandwich, coordinate vacuum effectiveness, improve heat-insulating property further.When rising to a certain degree atmospherically in insulating sandwich, Explosion-proof cap will be rushed to open, and just can prevent enclosure air pressure from continuing to rise.Safety cover can prevent Explosion-proof cap to be rushed to open backward outer to fly, and causes damage to personnel equipment.Elastic component can play the dual functions flown Explosion-proof cap pressurization and obstruction Explosion-proof cap.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is internal structure sectional view of the present utility model;
Fig. 2 is the enlarged diagram of the utility model flameproof apparatus.
In figure: 1, inner casing; 2, shell; 3, insulating sandwich; 4, vacuum-pumping tube; 5, ventilating hole; 6, breathing pipe; 7, Explosion-proof cap; 8, leak-proof gasket; 9, safety cover; 10, elastic component; 11, threaded stem; 12, adjusting nut.
Embodiment
A kind of natural gas storage tank peculiar to vessel being provided with flameproof apparatus as shown in accompanying drawing 1,2, comprises inner casing 1 and shell 2, is provided with the insulating sandwich 3 of filling heat insulator between described inner casing 1 and shell 2; Be plugged with vacuum-pumping tube 4 in described insulating sandwich 3, one end of described vacuum-pumping tube 4 is positioned at insulating sandwich 3, and it is outside that the other end is positioned at shell 2; Described shell 2 is provided with ventilating hole 5 and breathing pipe 6, described breathing pipe 6 one end is plugged on described ventilating hole 5, the other end is covered with Explosion-proof cap 7, the leak-proof gasket 8 preventing natural gas leaking is provided with between described breathing pipe 6 and the surface of contact of Explosion-proof cap 7, described Explosion-proof cap 7 is interference fit with breathing pipe 6 madial wall, to increase the frictional force between Explosion-proof cap 7 and breathing pipe 6.The bottom of described safety cover is fixed on shell 2 or on breathing pipe 6, can be fixed by screw, with the active force of more protection cover restriction Explosion-proof cap 7.
Described flameproof apparatus also comprises one and covers on breathing pipe 6, for preventing Explosion-proof cap 7 from flicking safety cover 9, is provided with elastic component 10 between described safety cover 9 and Explosion-proof cap 7.Described elastic component 10 is spring; elastic component 10 internal sleeve is provided with a threaded stem 11; one end of described threaded stem 11 is fixed on described safety cover 9; the other end screw thread is provided with an adjusting nut 12; one end of described elastic component 10 is connected on Explosion-proof cap 7, and the other end is connected on described adjusting nut 12, by rotating adjusting nut 12; the pressure of adjusting nut 12 pairs of elastic components 10 can be changed, so regulate Explosion-proof cap 7 wash pressure open.
Be filled with thermoinsulation material in insulating sandwich 3, coordinate vacuum effectiveness, improve heat-insulating property further.When rising to a certain degree atmospherically in insulating sandwich 3, Explosion-proof cap 7 will be rushed to open, and just can prevent shell 2 air pressure inside from continuing to rise.Safety cover 9 can prevent Explosion-proof cap 7 to be rushed to open backward outer to fly, and causes damage to personnel equipment.Elastic component 10 can play the dual functions pressurizeing to Explosion-proof cap 7 and hinder Explosion-proof cap 7 to fly.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
