Abstract
The utility model discloses a breather valve of a heat-preservation tank. The breather valve of the heat-preservation tank comprises a valve body arranged on the heat-preservation tank, the upper end of the valve body is a sealed upper sealed circular plate, the lower end of the valve body stretches into the heat-preservation tank and is a lower sealed circular plate, a steel pipe with one end stretching out of the heat-preservation tank is arranged on the lower sealed circular plate, and the other end of the steel pipe is fixed inside the valve body through a connecting plate. The breather valve of the heat-preservation tank has the main functions of sucking or exhausting air from the lower portion of a tank body, avoiding the breather valve blockage caused by rainy or snowy days, and being suitable for areas which are cold and often snowy.
Description
Technical field
The utility model relates to a kind of breathing valve, particularly a kind of breathing valve for heat insulation tank.
Background technology
Heat insulation tank is incubated when being usually used in the goods transportation of cold district, and breathing valve is the major part of heat insulation tank, usually is arranged at the heat insulation tank top, but cold district is because temperature is lower, the suction/exhousting hole of breathing valve freezes after being drenched by sleet easily, blocks the breathing valve port, causes breathing valve to lose efficacy.
Summary of the invention
In order to overcome defects, the utility model provides a kind of heat insulation tank breathing valve that is applicable to cold climate.
The utility model for the technical scheme that solves its technical matters and adopt is: a kind of heat insulation tank breathing valve, comprise the valve body that is arranged on the heat insulation tank, described valve body upper end is the upper envelope plectane of sealing, valve body lower end puts in and is the lower seal plectane in the heat insulation tank, the lower seal plectane is provided with an end and extend out to the outer steel pipe of heat insulation tank, and the steel pipe other end is fixed in the valve body by connecting panel.
As further improvement of the utility model, also be provided with successively brace panel and baffle plate between described connecting panel and lower seal plectane.
The beneficial effects of the utility model are: the breathing valve radical function that the utility model provides is or exhaust air-breathing from tank body lower part, avoids stopping up because sleety weather causes breathing valve, is fit to cold, frequent snowy area and uses.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Fig. 1 has shown the embodiment of a kind of heat insulation tank breathing valve of the utility model: comprise the valve body 2 that is arranged on the heat insulation tank 1, described valve body 2 upper ends are the upper envelope plectane 3 of sealing, valve body 1 lower end puts in and is lower seal plectane 4 in the heat insulation tank 1, the lower seal plectane is provided with an end and extend out to heat insulation tank 1 steel pipe 5 outward, steel pipe 5 other ends are fixed in the valve body 2 by connecting panel 6, and 4 of described connecting panel 6 and lower seal plectanes also are provided with brace panel 7 and baffle plate 8 successively.
