Technical Field

[0001] The utility model relates to the technical field of liquid level gauge protection, in particular to a detachable fireproof heat-insulating cover for a liquid level gauge. Background Art

[0002] The liquid level meter is an instrument used to detect the position of liquid and the position of the boundary. Because the detection environment, liquid density and other parameters are different, there are many types of corresponding liquid level meters, including magnetic flap level meter, magnetostrictive level meter, radar level meter, ultrasonic level meter, etc. The liquid level meter is equipped with a remote transmission supporting instrument. The sensing surface on the remote transmission supporting instrument should face and be close to the main conduit. After the wiring hole of the junction box is laid, it is required to be well sealed to prevent the intrusion of rain, high temperature, flame, etc., which may cause the remote transmission supporting instrument to malfunction.

[0003] The existing detachable fireproof insulation cover of the liquid level gauge often uses a single insulation layer to wrap and seal the liquid level gauge, and the sealing effect is poor. During use, water vapor will still enter the insulation cover, making the remote transmission instrument on the liquid level gauge invalid. At the same time, the fireproof insulation cover of the liquid level gauge can be used multiple times and often needs to be disassembled during use. The disassembly of the existing fireproof insulation cover of the liquid level gauge is relatively inconvenient, resulting in time-consuming and laborious disassembly work.

[0004] For this reason, we designed a detachable fireproof insulation cover for the level gauge. Utility Model Content

[0008] Preferably, the toothed chain can be bent to different degrees, the first fixed block and the second fixed block always remain parallel, and the vertical rod is perpendicular to the plane of the moving block.

[0009] Preferably, a rectangular notch is formed on the first fixing block, the vertical rod moves in the rectangular notch, and the distance between every two adjacent limiting columns is equal to the distance between every two adjacent teeth on the toothed chain.

[0010] Preferably, the water absorbing layer is provided with penetration holes, the heat-insulating layer is connected with a protective layer, and the protective layer and the liquid level meter are always kept in close contact.

When water vapor enters the thermal insulation cover, the water absorbing beads 13 and the balance frame 14 are made of special materials. A magnetic field is generated during the friction between the water absorbing beads 13 and the balance frame 14. The water vapor in the thermal insulation cover is adsorbed on the surface of the water absorbing beads 13 by the magnetic field. The small holes on the water absorbing beads 13 are in contact with the penetration holes 11. The penetration holes 11 absorb the water vapor adsorbed on the surface of the water absorbing beads 13 and store it in the water absorption layer 10.
