Abstract

The invention discloses a low-temperature preservation box with an air pressure balancing device, and relates to the technical field of refrigeration equipment. The low-temperature preservation box solves the problem that a lot of cooling energy inside a box body is lost after doors of existing low-temperature preservation boxes are opened, the boxes are expanded after the doors are closed due to hot air entering the boxes in the door opening process, the air pressure is lowered to be lower than the external barometric pressure and the doors cannot be opened. The low-temperature preservation box with the air pressure balancing device comprises a box body, a door body and the air pressure balancing device; an airflow channel is formed in a foaming layer of the box body or the door body; the air pressure balancing device comprises a one-way rubber valve, an airflow pipeline and rubber fixing rings, wherein the one-way rubber valve is fixed inside the airflow pipeline, the airflow pipeline is arranged inside the airflow channel and penetrates through the inner wall of the foaming layer and the outer wall of the box body or the door body, and the two ends of the airflow pipeline are fixed by the rubber fixing rings; the air pressure balancing device is arranged at the upper part of the box body; the one-way rubber valve is fixed to the middle of the airflow pipeline and is connected to the airflow pipeline in a sealed mode.

Description

A kind of cryopreservation case with air-pressure balancing device
Technical field
The present invention relates to technical field of refrigeration equipment, be specifically related to a kind of cryopreservation case with air-pressure balancing device.
Background technology
Atmospheric pressure the most difference in air under different temperatures.Temperature is the highest, and air expanded by heating rises the fastest, and air pressure is the lowest. In the use of refrigeration plant, after refrigeration product opens the door, causing the loss of High cooling power in relatively casing, hotter gas enters casing, The interior steam that entered by opening the door of rear cabinet of closing the door is affected and is expanded, and air pressure decreases below external atmosphere pressure, causes and cannot open the door now As.
Summary of the invention
It is an object of the invention to for above-mentioned deficiency, propose, by using air pressure balance air-flow one-way flow principle, can balance The pressure differential that process of refrigerastion raising middle flask inside and outside produces rapidly, prevents phenomenon of cannot opening the door, the one that can effectively pin again cold to have The cryopreservation case of air-pressure balancing device.
The present invention specifically adopts the following technical scheme that
A kind of cryopreservation case with air-pressure balancing device, including casing, door body and air-pressure balancing device, described casing or door Being provided with one section of gas channel in the foaming layer of body, air-pressure balancing device includes that unidirectional rubber valve, airflow pipeline and rubber are fixed Circle, unidirectional rubber valve is fixed in airflow pipeline, and airflow pipeline is arranged in gas channel and the inwall of through foaming layer and case Body or the outer wall of door body, the two ends of airflow pipeline are fixed by rubber ring for fixing respectively.
Preferably, described unidirectional rubber valve is towards the inner side of casing.
Preferably, described air-pressure balancing device is arranged at the top of casing.
Preferably, described unidirectional rubber valve is fixed on the middle part of airflow pipeline, and is tightly connected with airflow pipeline.
The invention have the advantages that: this has the cryopreservation case of air-pressure balancing device, when ambient pressure is more than gas in case Pressure type, outside air enters in case by unidirectional rubber valve, rapid equalisation case internal gas pressure, it is ensured that door body is normally-open;Work as case Interior beginning is freezed rapidly, and in case, pressure is more than external atmosphere pressure, and unidirectional rubber valve pins cold air and will not leak outside, it is ensured that cold is not Loss guarantees insulation.
Accompanying drawing explanation
Fig. 1 is the structural representation that air-pressure balancing device is installed in the door body of horizontal low temperature storage box;
Fig. 2 is the front view that air-pressure balancing device is installed on the casing of horizontal low temperature storage box;
Fig. 3 is the side view that air-pressure balancing device is installed on the casing of horizontal low temperature storage box;
Fig. 4 is the front view that air-pressure balancing device is installed on the casing of vertical low temperature storage box;
Fig. 5 is the side view that air-pressure balancing device is installed on the casing of vertical low temperature storage box;
Fig. 6 is air-pressure balancing device structural representation;
Fig. 7 is the air flow direction schematic diagram of air pressure balance dress.
Wherein, 1 is casing, and 2 is door body, and 3 is air-pressure balancing device, and 4 is unidirectional rubber valve, and 5 is airflow pipeline, and 6 are Rubber ring for fixing, 7 is foaming layer, and 8 is the inwall of foaming layer, and 9 is the outer wall of casing or door body.
Detailed description of the invention
With specific embodiment, the detailed description of the invention of the present invention is described further below in conjunction with the accompanying drawings:
As shown in figures 1 to 6, a kind of cryopreservation case with air-pressure balancing device, including casing 1, door body 2 and air pressure balance Device 3, is provided with one section of gas channel in the foaming layer 7 of casing 1 or door body 2, air-pressure balancing device 3 includes unidirectional rubber Valve 4, airflow pipeline 5 and rubber ring for fixing 6, unidirectional rubber valve 4 is fixed in airflow pipeline 5, its unidirectional rubber valve 5 towards the inner side of casing 1, and airflow pipeline 5 is arranged in gas channel and inwall 8 and the casing of through foaming layer or door body Outer wall 9, the two ends of airflow pipeline 5 are fixing by rubber ring for fixing 6 respectively, and air-pressure balancing device 3 is arranged at the upper of casing 1 Portion, unidirectional rubber valve 4 is fixed on the middle part of airflow pipeline 5, and is tightly connected with airflow pipeline 5.
As it is shown in fig. 7, the operation principle of air-pressure balancing device is: when normally freezing, the temperature inside the box is low, belong to high-pressure side, high Pressure side gas flows through A side, and air-flow is want by, at the extruding unidirectional rubber valve doorway all fallen over each other in B side, making valve port also come the least Finally close, cold is locked in box house.After opening the door, a large amount of colds run off, and a large amount of steam enter in case, balance case The interior pressure with atmospheric pressure, closes behind the door at this, and the temperature inside the box raises and produces low pressure, and B side gases at high pressure are by unidirectional rubber when the time comes Valve port pours in the case of A side, pressure in tandem-driving bogie.
This air-pressure balancing device is applied in capacity refrigeration product more than 300 liters, can greatly facilitate and open in process of refrigerastion Close the door, it is to avoid owing to the poor impact that is stressed causes opening the door.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, the art Change that technical staff is made in the essential scope of the present invention, retrofit, add or replace, also should belong to the protection of the present invention Scope.
