Description
Technical field
The present invention is used for refrigeration system equipment technical field, more particularly to a kind of uniform knockout of refrigerant.
Background technology
In refrigeration system, refrigerant is after throttling arrangement, and pressure reduction flows into evaporator.Can refrigerant uniform equivalent
Ground is assigned to each branch road of evaporator, and the performance or even whole refrigeration system on evaporator have vital influence.Point
Liquid device is an important servicing unit, is installed in before evaporator, uniformly distributes refrigerant to evaporator each branch road
Device.There is distribution uneven phenomenon in the existing knockout of practical application, if distribution is uneven, some branch refrigerant mistakes can be made
It is many, make evaporimeter frosting, as a result evaporate incomplete, band liquid flows out evaporator, and some refrigerants are very few, it is impossible to make full use of evaporation
Device heat transfer area, aggregate performance is, refrigerating capacity declines, and is likely to result in absorbing gas belt liquid, has a strong impact on performance of refrigerant systems and can
By property, the problems such as complete machine capability is not enough.
Therefore influence of the knockout to evaporator is very big, and particularly cryogenic temperature is lower, influences bigger.
The reason for knockout is uneven：Knockout is arranged on after expansion valve, refrigerant liquid ability after reducing pressure by regulating flow
The incoming heat of tube wall is inevitably absorbed to knockout, therefore along journey liquid, flash steam is produced, liquid is mixed in the form of bubbles
In body, when the separating tube in entrance knockout downstream of the bubble without control, some separating tube bubble in liquid are some more, may result in
Flow is less than normal, causes knockout assignment of traffic uneven.
The content of the invention
To solve the above problems, the present invention provides a kind of uniform knockout of refrigerant for evenly distributing flow.
The technical solution adopted for the present invention to solve the technical problems is：A kind of uniform knockout of refrigerant, including point liquid
Distribution cavity is provided with inside device and feed pipe, the knockout, knockout is provided with inlet opening in the front side of distribution cavity, in distribution cavity
Rear side is provided with some separating tube holes, and throttle orifice is provided between the distribution cavity and inlet opening, and the feed pipe is docked with inlet opening,
The feed pipe has spiral helicine feed flow pore.
The improvement of technical solution of the present invention is further used as, the separating tube pore size distribution is in the periphery of distribution cavity.
It is further used as the improvement of technical solution of the present invention, the axle of the inlet opening, throttle orifice and distribution cavity along knockout
Line is sequentially coaxially set.
It is further used as the improvement of technical solution of the present invention, the knockout is provided with by rear side and to extend to distribution along axis
The distribution cone of intracavitary, the conical surface of each separating tube hole along the distribution cone is uniformly distributed.
It is further used as being all connected with separating tube at the improvement of technical solution of the present invention, each separating tube hole.
It is further used as the improvement of technical solution of the present invention, the feed pipe is helix tube, the head number of the helix tube >=
3, length and the equivalent diameter ratio of the helix tube are R, 8 ＜ R ＜ 10.
The improvement of technical solution of the present invention is further used as, the aperture of the throttle orifice is the 60% of inlet opening aperture.
The improvement of technical solution of the present invention is further used as, the aperture of the distribution cavity endoporus is inlet opening aperture
120%.
Beneficial effects of the present invention：The present invention is in use, refrigerant is after expansion valve, into the feed pipe before knockout
With spiral helicine feed flow pore, promote liquid in rotation, bubble is lightweight will to concentrate on tube hub, into the throttling of knockout
Hole, first by compression and then extension, makes bubble dispersion and fining, the separating tube hole in each downstream is uniformly flowed into liquid, so as to reach
Improve the purpose of the inhomogeneities of original knockout.
Brief description of the drawings
