Abstract
The utility model relates to an electronic storehouse sealing structure for a magnetostriction liquid indicator. The electronic storehouse sealing structure comprises an electronic storehouse body, an electronic storehouse support and an electronic storehouse end cover, wherein the electronic storehouse support and the electronic storehouse end cover are arranged in the electronic storehouse body, a planar rectangular sealing washer is arranged between the end surface of the electronic storehouse body and the inner end surface of the electronic storehouse support, and an O-ring is arranged between the inner wall of the electronic storehouse body and the outer surface of the electronic storehouse support; and another planar rectangular sealing washer is arranged between the end surface of the electronic storehouse body and the inner end surface of the electronic storehouse end cover, and another O-ring is arranged between the inner wall of the electronic storehouse body and the outer surface of the electronic storehouse end cover. The electronic storehouse sealing structure disclosed by the utility model has a simple structure, and is convenient to mount; by utilizing a single-point double-seal manner of combining the planar rectangular sealing washers with the O-rings, the planar rectangular sealing washers are in contact with atmosphere (or oil gas), and the O-rings are isolated from the atmosphere (or the oil gas), so that the sealing effect can be effectively improved, the sealing service life is prolonged, the use cost can be greatly reduced, the labor intensity of workers is reduced, and the effective working efficiency of devices is effectively improved.
Description
Technical field
The utility model belongs to the magnetostriction liquidometer technical field, particularly a kind of magnetostriction liquidometer electronics storehouse sealing configuration.
Background technique
Magnetostriction liquidometer is widely used in the measurement of liquid level height in oil tank or the underground tank, since its installation and operation in oil tank, the environment very severe, therefore, signals collecting and processing circuit adopt the intrinsic safety type design, to guarantee the explosion-proof performance of processing circuit under normal running (operation) conditions.But in order to make magnetostriction liquidometer (as: environment such as hot and humid, circuit burn into short circuit, heavy current impact) safe operation under particular surroundings, the sealability of its electronics warehouse is most important.
At present, the sealing of most of electronics warehouses is single sealings of adopting O type circle or rectangular loop, and sealed material is nitrile butadiene rubber.Nitrile butadiene rubber is aging easily under exposed environments, causes the seal failure of electronics warehouse, brings hidden danger for the safe operation of magnetostriction liquidometer.Now, be periodic replacement O type circle or rectangular seal at effective solution of electronics warehouse seal failure problem, cause user cost to increase greatly.
The model utility content
The purpose of this utility model provides the low magnetostriction liquidometer of a kind of simple in structure, good sealing effect, user cost with electronics storehouse sealing configuration.
For achieving the above object, the technical solution of the utility model is: a kind of magnetostriction liquidometer electronics storehouse sealing configuration, comprise electronics bin bracket and electronics storehouse end cap in electronics warehouse and the electronics warehouse, be provided with the planar rectangular seal washer between described electronics warehouse end face and the electronics bin bracket interior edge face, be provided with O type circle between electronics warehouse inwall and the electronics bin bracket outer surface; Be provided with the planar rectangular seal washer between electronics warehouse end face and the electronics storehouse end cap interior edge face, be provided with O type circle between electronics warehouse inwall and the electronics storehouse end cap outer surface.
Described planar rectangular seal washer and O type circle material are fluorine rubber.
Compared with prior art, the utility model has the advantages that: the utility model comprises electronics bin bracket and the electronics storehouse end cap in electronics warehouse and the electronics warehouse, be provided with the planar rectangular seal washer between described electronics warehouse end face and the electronics bin bracket interior edge face, be provided with O type circle between electronics warehouse inwall and the electronics bin bracket outer surface; Be provided with the planar rectangular seal washer between electronics warehouse end face and the electronics storehouse end cap interior edge face, be provided with O type circle between electronics warehouse inwall and the electronics storehouse end cap outer surface, it is simple in structure, be convenient to install, the single-point double-sealing mode that adopts planar rectangular seal washer and O type circle to combine, the planar rectangular seal washer contacts with atmosphere (or oil gas), O type circle and atmosphere (or oil gas) are isolated, can effectively improve sealing effect, prolong sealing life, and can reduce user cost greatly, reduce labor strength, effectively improve equipment effective operation efficient.
