Abstract
The invention relates to an induction device and in particular relates to an excess-prevention floating ball induction device for a liquidation tank. The problem that the conventional liquefied natural gas is easy to overfill is mainly solved. The excess-prevention floating ball induction device comprises a gravity inductor (2) fixedly disposed at a filling opening of the liquidation tank (1), a connection line (3) of which one end is connected to the gravity inductor, and a floating ball (4) fixedly disposed at the other end of the connection line (3), wherein the other end of the connection line (3) extends into the liquidation tank (1) through the filling opening of the liquidation tank (1); and the floating ball (4) is positioned in the liquidation tank (1). The excess-prevention floating ball induction device has the effect of preventing overfilling, is reliable in measure and safe to store, and has extremely high practical value and application value.
Description
[technical field]
Invention relates to a kind of device of anti-overfilling, and what be specifically related to is anti-excessive ball float induction installation for liquefied pot.
[background technique]
Liquefied natural gas (LNG) tank (LNG storage tank) is the specialty products of storage liquid liquefied oil gas, belongs to special equipment, and conventional gas cylinder will be placed on draughty place, should not be less than 1.5m with the spacing of burning things which may cause a fire disaster, thermal source.Gas cylinder is forbidden with fire is roasting, boiling water is boiling hot or be exposed to the sun in the sun.Want the tightness at the places such as running check gas cylinder valve and pipe joint, keep air tight.
The potential safety hazard that conventional LNG storage tank causes because of overfilling medium in filling process, thus we need a kind of device of the anti-overfilling be applied on liquefied pot very necessary.
[summary of the invention]
The object of the invention is to: for the problem of the easy overfilling of existing LNG Liquefied natural gas, a kind of anti-excessive ball float induction installation for liquefied pot that can solve the problem is provided.
For solving above-mentioned shortcoming, technological scheme of the present invention is as follows:
For the anti-excessive ball float induction installation of liquefied pot, comprise and be fixed on that liquefied pot fills gravity sensor on mouth, one end is connected to the connecting line on gravity sensor and is fixed on the ball float of the connecting line the other end; The described connecting line the other end fills mouth by liquefied pot and extends into liquefied pot, and this ball float is positioned at liquefied pot inside.
Further, fill mouth described in and be positioned at liquefied pot top.
The gas volatilized in filling process impacts effect of the present invention, and described liquefied pot is also provided with air entraining pipe.
The present invention compared with prior art, has the following advantages and beneficial effect:
Adopt ball float induction installation effectively can avoid the problem of LNG Liquefied natural gas overfilling in the present invention, increase Safety performance of the present invention.Ball float induction installation comprises gravity sensor, connecting line and ball float composition, by gravity sensor induction ball float total amount, thus determines whether liquified natural gas reaches ball float position, thus determine whether to have filled, this structure is simple, with low cost, and is applicable to applying.
[accompanying drawing explanation]
Fig. 1 is overall structure schematic diagram of the present invention.
Wherein, the component name that in figure, reference character is corresponding is called:
1-liquefied pot, 2-gravity sensor, 3-connecting line, 4-ball float, 5-air entraining pipe.
[embodiment]
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment
As shown in Figure 1, for the anti-excessive ball float induction installation of liquefied pot, comprise and be fixed on that liquefied pot 1 fills gravity sensor 2 on mouth, one end is connected to the connecting line 3 on gravity sensor and is fixed on the ball float 4 of connecting line 3 the other end; Described connecting line 3 the other end fills mouth by liquefied pot and extends into liquefied pot, and it is inner that this ball float 4 is positioned at liquefied pot 1.
Liquefied pot 1 in the present invention by housing, be arranged on housing fill mouth and outlet port, the safety installations be fixed on housing form, described housing is made up of shell, inner casing and the thermoinsulation material be filled between shell and inner casing, the described mouth that fills is arranged at case top, and outlet port is arranged at housing bottom, this fills on mouth and then connects anti-excessive ball float induction installation of the present invention.
The gas volatilized in filling process impacts effect of the present invention, and described liquefied pot is also provided with air entraining pipe 5.
As the setting of optimum, described thermoinsulation material is aerogel blanket, and this aerogel blanket is with nanometer titanium dioxide silica aerogel for material of main part, the flexible heat-insulating felt be composited by special process.Aerogel blanket has the characteristics such as Rou Ruan ﹑ easy Cai Jian ﹑ density is little, hydrophobic Wu machine Fang Huo ﹑ entirety, environmental protection.
In order to reach best Safety performance, described safety installations comprises pressure sensitive device and thermometer.
According to above design, just the present invention can be realized preferably.
