Abstract
The utility model discloses a magnetic vacuum liquidometer, mainly comprising a main guide pipe, a liquid display and a magnetic floating ball. The wall casing of the main guide pipe is composed of a double-layer housing. An enclosed cavity is disposed between the double-layer housing. The main guide pipe is provided with a vapor phase connection hole and a liquid phase connecting hole, by which the internal part and the external part of the main guide pipe are communicated. The main guide pipe is also provided with an air hole, which is disposed in the outer wall housing of the main guide pipe. The magnetic vacuum liquidometer is advantageous in that the structure is simple; the ambient temperature outside of the main guide pipe is isolated from the main guide pipe through a vacuum cavity, and thereby the liquid in the main guide pipe can be prevented from solidification without external heating in the environment of low temperature; even in the high-temperature environment, some liquid medium will not be affected.
Description
Technical field
The utility model relates to the technical field of liquid level gauge, more particularly relates to the technical field of magnetic fluid level gauge.
Background technology
Liquid level gauge is to utilize the principle of linker to show the instrument of liquid level in the container in real time, be applicable to the reservoir of liquid medium, generally use magnetic fluid level gauge for the higher place of safety requirements, magnetic fluid level gauge mainly is made of main pipe, fluid level gauge, magnetic ball float and blowoff valve, and its main pipe and fluid level gauge are separated fully.But its deficiency that exists in use is, when this magnetic fluid level gauge uses under low temperature environment, liquid in the main pipe will solidify blocks main pipe, thereby make liquid level gauge can't show the true liquid level in the container, outside main pipe is heated during the way that adopts at present usually, make the liquid that can not in the main pipe solidify, need the special messenger to monitor so on the one hand and prevent that the liquid in the main pipe from solidifying; Easily some liquid medium in the container is exerted an influence after main pipe is heated on the other hand, also can bring potential safety hazard when serious.Equally, when using under the higher temperature environment of this magnetic fluid level gauge in the external world, some liquid medium in the main pipe also can exert an influence.
The utility model content
The purpose of this utility model provides a kind of simple in structure in order to solve above-mentioned deficiency exactly, and is easy to use, need not external heating under low temperature environment, the magnetic vacuum liquid level gauge that some liquid medium also can not exert an influence under hot environment.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
Magnetic vacuum liquid level gauge, it mainly includes main pipe, liquid display and magnetic ball float, the wall shell of described main pipe is made of double Shell, between this double Shell, form airtight chamber, offer vapour phase connecting hole and liquid phase connecting hole on the described main pipe, this vapour phase connecting hole and liquid phase connecting hole are connected the inside of main pipe with the outside, also offer pore on the described main pipe, and this pore is positioned on the exine shells of main pipe.
The vapour phase connecting hole of offering on the described main pipe and liquid phase connecting hole are distribution up and down.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: simple in structure, the wall shell of main pipe is made into the double Shell that is provided with chamber therebetween, again this chamber is evacuated, so just can completely cut off outside main pipe by the chamber of this vacuum environment temperature that main pipe is outer, make the liquid in the main pipe need not under low temperature environment to prevent that by external heating it from solidifying that some liquid medium can not exert an influence yet under hot environment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
By shown in Figure 1, magnetic vacuum liquid level gauge, it mainly includes main pipe 1, liquid display 2 and magnetic ball float 3, the wall shell of described main pipe 1 is made of double Shell, between this double Shell, form airtight chamber 4, offer on the described main pipe 1 and be vapour phase connecting hole 5 and the liquid phase connecting hole 6 that distributes up and down, this liquid flow hole 6 is connected the inside of main pipe 1 with the outside, be used for being connected with container, also offer pore 7 on the described main pipe 1, this pore 7 is positioned on the exine shells of main pipe 1, utilize this pore 7 that the gases in the airtight chamber 4 are extracted out and form the vacuum shape, these pore 7 places can connect the detection of negative pressure valve, utilize the detection of negative pressure valve can be very easily by the vacuum tightness situation in pore 7 detection chambers 4, described liquid display 2 and magnetic ball float 3 are same as the prior art, need not to repeat at this.
Claims (2)
1. magnetic vacuum liquid level gauge, it mainly includes main pipe, liquid display and magnetic ball float, it is characterized in that: the wall shell of described main pipe is made of double Shell, between this double Shell, form airtight chamber, offer vapour phase connecting hole and liquid phase connecting hole on the described main pipe, this vapour phase connecting hole and liquid phase connecting hole are connected the inside of main pipe with the outside, described main pipe also offers pore, and this pore is positioned on the exine shells of main pipe.
2. magnetic vacuum liquid level gauge according to claim 1 is characterized in that: the vapour phase connecting hole of offering on the described main pipe and liquid phase connecting hole are up and down and distribute.
