Abstract
The invention discloses a kind of freezer air-cooler double-pipe for defrosting drain non-return valves, the gum sleeve of shell and installation inside the shell including both ends open, the shell, which is connected by special-shaped female coupling with special-shaped straight tube with outside, to be constituted, in the upper section socket of the gum sleeve and the lower section of special-shaped female coupling, the gum sleeve is one-time formed special hose, the upper end of special hose is tube-shaped structure, and lower end is self-closing flat O-shaped structure.Non-return valve of the invention, which has, to be automatically controlled outside defrost water forward direction discharge library, the reversed non-return function of hot-air, can be to avoid hot-air outside negative pressure sucking library caused by when air-cooler work, to guarantee the stabilization of library temperature, freezer machine frost is reduced, the energy consumption of freezer is reduced.
Description
Technical field
The present invention relates to a kind of check valve arrangements, and in particular to a kind of freezer air-cooler double-pipe for defrosting drain non-return valve.
Background technique
Air-cooler is dried forward when working, so that air-cooler rear portion, lower part, form negative pressure in drainpipe, it is wet outside freezer
Hot-air is inhaled into air-cooler and freezer, is caused air-cooler frosting exacerbation, freezer heating, is increased freezer energy consumption.
Summary of the invention
To solve the above problems, the present invention provides a kind of freezer air-cooler double-pipe for defrosting drain non-return valves.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of freezer air-cooler double-pipe for defrosting drain non-return valve, the rubber sleeve of shell and installation inside the shell including both ends open
Pipe, the shell, which is connected by special-shaped female coupling with special-shaped straight tube with outside, to be constituted, upper section socket and the abnormity of the gum sleeve
On the lower section of female coupling, the gum sleeve is one-time formed special hose, and the upper end of special hose is tube-shaped structure,
Lower end is self-closing flat O-shaped structure.
Further, the shell uses tri- type polypropylene of PPR().
Further, the gum sleeve uses silicone rubber material.
Non-return valve of the invention, which has, to be automatically controlled outside defrost water forward direction discharge library, and the reversed non-return function of hot-air is interior
The bigger silicon rubber of external differential (rubber) molding sleeve closure is tighter, and damp-heat air outside freezer is prevented to be inhaled into, can be to avoid cold
Hot-air reduces air-cooler frost to guarantee the stabilization of library temperature outside the sucking of negative pressure caused by when blower works library, reduces
The energy consumption of freezer；When air-cooler heats defrosting, defrosting water squeezes non-return valve silicon rubber (rubber) molding casing under the effect of gravity
Draining is completed in the lower part of elastic closure.

Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection scope.
As Figure 1-Figure 5, the embodiment of the invention provides a kind of freezer air-cooler double-pipe for defrosting drain non-return valves, including two
The shell 1 of end opening and the gum sleeve 2 being mounted in shell 1, the shell 1 is by special-shaped female coupling 11 and the outer tooth of abnormity
Straight-through 12, which are connected, is constituted, in the upper section socket of the gum sleeve 2 and the lower section of special-shaped female coupling 11, the gum sleeve 2
For one-time formed special hose, the upper end of special hose is tube-shaped structure, and lower end is self-closing flat O-shaped structure.
As shown in fig. 6, this specific implementation has in application, the non-return valve A is mounted on the double-pipe for defrosting drain of air-cooler
Body, double-pipe for defrosting drain is truncated, 11 welding of the tail end of upper section and special-shaped female coupling, the head end of lower end and special-shaped straight tube with outside
Installation can be completed in 12 weldings.
The working principle of this specific implementation are as follows: when in freezer setting control 0C ° ~ 2C ° of temperature, Ku Wen reach and maintain 0C ° ~
When 2C ° of stage, Non-return valve for drain-pipe is closed, and is blocked inner air and outer air flowing, is seen Fig. 7；Through (0.5 hour ~ 1.5 is small after a period of time
When), temperature recovery to 2C ° or more, start to work 5 ~ 15 minutes by air-cooler, and blower rear portion, lower part form negative pressure in drainpipe,
Non-return valve for drain-pipe is closed, and prevents hot-air outside library from entering, which sees Fig. 8；To 0C °, air-cooler stops working library temperature drop.Such as
This is repeated multiple times, and by 18 ~ 24 hours, air-cooler frosting was more, and air-cooler heat exchange efficiency reduces, and air-cooler opens electric heating
Frost continues 30 ~ 40 minutes, and defrosting water is flowed out by drainpipe, and Non-return valve for drain-pipe is opened, and sees Fig. 9, repeatedly cycle operation.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make a variety of changes or modify within the scope of the claims, this not shadow
Ring substantive content of the invention.In the absence of conflict, the feature in embodiments herein and embodiment can any phase
Mutually combination.
