Abstract
The utility model 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) fixed 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) fixed 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); the floating ball (4) is positioned in the liquidation tank (1). The excess-prevention floating ball induction device has an effect of preventing overfilling, has a reliable measure, is safe to storage and has extremely high practical and application value.
Description
[technical field]
Model utility relates to a kind of device of anti-overfilling, and what be specifically related to is the 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.That gas cylinder is forbidden is roasting with fire, boiling water scalds or is exposed to the sun in the sun.The tightness of wanting running check gas cylinder valve and pipe joint etc. to locate, keep air tight.
The potential safety hazard that conventional LNG storage tank causes because of overfilling medium in filling process, thereby we need a kind of device that be applied in the anti-overfilling on liquefied pot very necessary.
[summary of the invention]
The purpose of this utility model is: for the problem of the easy overfilling of existing LNG Liquefied natural gas, provide a kind of anti-excessive ball float induction installation for liquefied pot that can address the above problem.
For solving above-mentioned shortcoming, the technical solution of the utility model is as follows:
For the anti-excessive ball float induction installation of liquefied pot, comprise that being fixed on gravity sensor, one end that liquefied pot fills on mouth is connected in 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, described in, fill mouth and be positioned at liquefied pot top.
For fear of the gas volatilizing in filling process, effect of the present utility model is impacted, on described liquefied pot, be also provided with air entraining pipe.
The utility model compared with prior art, has the following advantages and beneficial effect:
In the utility model, adopt ball float induction installation can effectively avoid the problem of LNG Liquefied natural gas overfilling, increase Safety performance of the present utility model.Ball float induction installation comprises gravity sensor, connecting line and ball float composition, by gravity sensor, responds to ball float total amount, thereby determines whether liquified natural gas reaches ball float position, thereby determine whether to have filled, this is simple in structure, with low cost, and is applicable to applying.
[accompanying drawing explanation]
Fig. 1 is overall structure schematic diagram of the present utility model.
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 utility model is described in further detail, but mode of execution of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, for the anti-excessive ball float induction installation of liquefied pot, comprise that being fixed on gravity sensor 2, one end that liquefied pot 1 fills on mouth is connected in the connecting line 3 on gravity sensor and is fixed on the ball float 4 of connecting line 3 the other ends; Described connecting line 3 the other ends fill mouth by liquefied pot and extend into liquefied pot, and this ball float 4 is positioned at liquefied pot 1 inside.
Liquefied pot 1 in the utility model is comprised of housing, the safety installations that fills mouthful and extract out mouthful, is fixed on housing that is arranged on housing, described housing by shell, inner casing and be filled in shell and inner casing between thermoinsulation material form, the described mouth that fills is arranged at case top, and extract mouth out, be arranged at housing bottom, this fills and on mouth, connects anti-excessive ball float induction installation of the present utility model.
For fear of the gas volatilizing in filling process, effect of the present utility model is impacted, on described liquefied pot, be also provided with air entraining pipe 5.
As optimum setting, described thermoinsulation material is aerogel blanket, and this aerogel blanket is take nanometer titanium dioxide silica aerogel as material of main part, the flexible heat-insulating felt being composited by special process.Aerogel blanket has the characteristics such as the easy Cai Jian of Rou Ruan ﹑ ﹑ 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 can realize preferably the utility model.
Claims (3)
