Technical field

This utility model is related to the volatile liquid storage tank device of chemical industry metallurgical industry, more particularly to a kind of air valve knot Structure body and volatile liquid storage device.

Background technology

Volatility refers to the process of that compound is changed into gas or steam from solid or liquid.One of physical property.A kind of thing The volatility of matter refers to that it becomes the tendency of gas from liquid or solid.There is the dirt that a class is referred to as volatile organic matter (vocs) Dye thing, these compounds are once exposed in the air and promptly will become gas from liquid or solid.A kind of material is easier Volatilization, being more possible to disappears arrives in the air.For example, chemical industry metallurgical industry usually uses volatile liquid, and volatile liquid how Storage becomes the technical problem that those skilled in the art constantly explore.

In prior art, typically there is the pipeline opening of two on volatile liquid storage tank top, for feeding and entering flat during blowing Weighing apparatus tank external and internal pressure.For ensureing the sealed storage of storage pot liquid, the often common valve such as mounting ball valve, stop valve on pipeline. But during actual blowing, for reaching internal and external pressure balance to guarantee that blowing is smooth it is necessary to open the one of of top Valve, inevitably be will result in volatilization gas and is escaped into outside flow container by this valve, leads to air pollution even person peace Full threat.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of air valve structure body and volatile liquid Storage device, structure is simply it is ensured that avoid the effusion of volatilization gas while blowing is smooth.

In order to achieve the above object, the technical solution adopted in the utility model is:

A kind of air valve structure body, including upper movable joint lid, baffle ring, housing, hollow ball, lower slip-knot lid；Described baffle ring is arranged at At case top opening, upper movable joint lid is arranged above baffle ring, and lower slip-knot lid is connected with housing bottom, and hollow ball is arranged at housing Inside.

As preferred embodiment of the present utility model, close in setting one between upper movable joint lid described in the utility model and baffle ring Seal.

As preferred embodiment of the present utility model, arrange close between housing described in the utility model and lower slip-knot lid Seal.

As preferred embodiment of the present utility model, aperture is gradually reduced housing described in the utility model from top to bottom；Empty Bulbus cordis be located at enclosure interior, hollow ball with diameter greater than lower seal aperture, less than housing minimum-value aperture.

A kind of volatile liquid storage device, including volatile liquid storage tank, the top of described volatile liquid storage tank sets Put two pipeline opening, wherein one pipeline opening is connected with one end of air valve structure body；Another two pipeline opening respectively with pipeline valve One end connects, and the other end of pipeline valve is connected with the discharge port of feed liquid car and sample tap respectively.

Compared with prior art, volatile liquid storage tank loading operation and stopping loading operation are same as the prior art: dress During material, open discharge pipe, the common pipe valve on return-air duct, the liquid self-unloading material mouth in feed liquid car is through discharge duct road junction Flow into storage tank, the gas in storage tank escapes into feed liquid car by return-air duct；When stopping charging, two valves are turned off.

Compared with prior art, the beneficial effects of the utility model are: with during storage during charging, hollow ball in gravity and is waved Send out under the collective effect of gas pressure, compress lower seal, gas does not escape out storage tank；During blowing, common pipe valve still closes Close, tank inner pressure is released with feed liquid and reduced, the space that air passes through hollow ball and lower seal enters storage tank it is ensured that in storage tank Pressure and extraneous balance, structure is simple, can effectively guarantee volatile liquid storage tank during charging, storage, blowing, air valve is tied Structure body operates without manual control switch, and avoids the effusion of volatilization gas while guarantee blowing is smooth, is particularly well-suited to expect Liquid car discharge position remote operation in the case of distant with volatile liquid storage device.
