Description
Technical field
The utility model is related to refrigerator technical field, and in particular to a kind of check valve and the refrigerator with the check valve.
Background technology
Use spring or elastic valve plate more existing check valve, also have and the principle such as liquidated using gravity and Fluid pressure,
Make air or other fluids unidirectional by valve body, also have using theory of mechanics or electronically controlled valve block switch motion to realize stream
The unidirectional of body passes through.The first-class switch by valve of the such as fire hose unidirectionally passes through to realize, some relief valves then pass through setting
The balance of elastic force and pressure realizes that one-way fluid passes through after being broken, and the check valve also having make use of the principle of gravity, such as Fig. 1-2
It is shown.
When 2 valve blocks by deadweight with 1 valve body realize closing seam, have fluid by when, or uniaxial pressure increase when, pressure differential
Overcome the valve block of Action of Gravity Field jack-up 2,2 valve blocks is left 1 valve body, fluid passage conducting, fluid unidirectionally passes through, but when the pressure on opposite
When power increases, 2 valve blocks are worked by pressure and deadweight one and are closely sealed 1 valve body, realize the one-way conduction of fluid.Remaining
Check valve also uses the structure substantially.
Refrigerator opens the door extremely difficult again after a switch gate, in the short time, and its reason is hot outside in enabling
When enter inside refrigerator, back of closing the door is sealed in inside refrigerator, the air pressure reduction after being cooled inside refrigerator, outside refrigerator
Atmospheric pressure, the pressure differential inside and outside refrigerator acted in the door body of refrigerator, embodies very big pressure, will so that opening door body
Overcome this pressure, open the door difficult, just can be certainly after external and internal pressure difference until due to the air circulation of refrigerator inside and outside, eliminating
Switch gate such as.And the gas passage of normal open often results in cold in refrigerator and leaked, the problems such as causing high energy consumption, outside condensation,
Multiple switching door is implicitly present in demand in the sometimes short time, therefore to solve problems, it is necessary to be installed on refrigerator unidirectional
Valve, it is to avoid the problems such as cool air leakage usually, can balance inside and outside differential pressure, the problem of solving to open the door difficult again.
Existing such check valve generally existing cost is high, and material requirements height and installation dimension and application scenario are restricted etc.
Fluid properties etc. are often had specific requirement by defect, sometimes also have a larger energy loss, install and maintenance requirement compared with
Height, reliability and life-span also have much room for improvement.
Utility model content
First purpose of the present utility model is to be directed to above-mentioned deficiency, it is proposed that one kind is small suitable for contrast pressure, and fluid is close
A kind of check valve in the small environment of degree.
The utility model is specifically adopted the following technical scheme that：
A kind of check valve, including valve body and valve block, the valve body are in the cavity of both ends open shape, and valve block is arranged at cavity
Interior, the central axis upright of plane and cavity where valve block, the center of valve body is provided with fluid through-hole.
Preferably, the valve block is provided with more than a piece of, is set successively along the centerline axis parallel of valve body.
Preferably, the valve block is made of flexible elastomeric material.
Preferably, the valve body is made of metal material or plastic material.
Preferably, closure state is in when pressure of the fluid through-hole in valve block both sides is equal.
Preferably, the valve block is individual layer valve block.
Preferably, the valve block is multilayer valve block.
Second purpose of the present utility model be propose one kind can effective Fast-Balance refrigerator inside and outside differential pressure, solve cold
The refrigerator with check valve of the difficult problem of cabinet enabling.
The utility model is specifically adopted the following technical scheme that：
A kind of refrigerator with check valve, using check valve as described above, including casing and the door being fastened on casing
Body, the side wall of casing is provided with the check valve of insertion casing inside and outside wall, the drainpipe of bottom half and is also equipped with check valve.
Preferably, gasket is provided between the casing and door body.
The utility model has an advantageous effect in that：Valve body and valve block are integral type structure, in use will not be by
Cause the phenomenon that valve body and valve block depart from extraneous impulsive force, improve the stability of check valve；Valve block without outside elastic force,
Freely, energy loss is few for opening and closing, easily realizes；The check valve is housed on refrigerator, inner and outer air pressure imbalance is not only solved and leads
The enabling of cause is difficult, is also used as pressure release check valve and uses, can also be used as check valve of water drainage, it is ensured that casing it is close
