Description
Technical field
The present invention relates to a kind of auxiliary equipment of air-conditioning, specifically is a kind of knockout.
Background technology
Knockout also claims current divider, claim liquid distributor again, it is an auxiliary equipment between expansion valve and the evaporimeter in the refrigeration system, and its effect is the cold-producing medium two-phase mixture that expansion valve (capillary) comes out to be assigned in each road coil pipe of evaporimeter evenly, equally go.
The knockout of prior art is as a whole, generally being brass dashes or five metals machine-shaping through red, and hole respectively in two ends then, welds the come and go copper pipe of evaporation coil of self-expanding valve more respectively, its import department is big chamber, is each the separatory passage that is communicated with its chamber again.There is following shortcoming in this knockout:
1, because the gas-liquid two-phase cold-producing medium that comes from expansion valve just enters the separatory corridor diversion through its chamber without evenly mixing fully, so, do not reach the effect of even equivalent separatory, thereby cause evaporimeter heat exchange amount to reduce, the expansion valve misoperation also causes evaporimeter frosting inhomogeneous, and then directly influences the refrigeration of refrigeration system, simultaneously, also increased energy consumption.
2, the welding owing to this knockout rear and front end copper pipe all concentrates on the main body, the heated time of knockout is long, oxide skin is more in its separatory passage, its impurity is also more, like this, just increased the resistance of separatory passage, and the resistance of each separatory passage is different again, so, more aggravated the described separatory inequality of last point.
3, in order to make the gas-liquid two-phase refrigerant mixed in the knockout even as much as possible,, generally realize that by the length that prolongs chamber so the volume of this knockout is bigger, its cost is higher to reach the effect of even equivalent separatory as much as possible.
4, because the size of this monoblock type knockout is changeless, so in practice, its compatibility is relatively poor.
5, the current divider of prior art is not all established fixture, sometimes because the mobile evaporation coil that makes of cold-producing medium produces slow-action and resonance, thereby, make the inner phenomenon that produces the cold-producing medium turbulent flow of evaporation coil.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of and can make the gas-liquid two-phase cold-producing medium evenly mix with even equivalent separatory and volume is little, cost low and the good knockout of compatibility.
Technical scheme of the present invention is, a kind of knockout with following structure is provided, and comprises a plurality of separatory passages; It also comprises the liquid-dividing head that is provided with branch liquid chamber and valve core chamber, the spool that is provided with the gas-liquid through hole and tube connector; Described liquid-dividing head is removable the connection with tube connector; Described a plurality of separatory passage is positioned at an end of liquid-dividing head and is communicated with a minute liquid chamber; Described spool sliding fit is communicated with the internal channel that divides liquid chamber and tube connector in valve core chamber and by the gas-liquid through hole, the aperture of gas-liquid through hole is less than the diameter of minute liquid chamber and the internal diameter of tube connector; Divide between liquid chamber and the valve core chamber to seal, seal between valve core chamber and the tube connector internal channel.
After adopting above structure, the present invention compared with prior art has the following advantages:
1, the gas-liquid two-phase cold-producing medium that comes from expansion valve, gas-liquid through hole through spool fully mixes earlier, then through minute liquid chamber to each separatory corridor diversion, like this, improve the effect of the shunting uniformity and equivalent separatory, thereby guaranteed the uniform heat exchange of evaporimeter, increased the heat exchange amount of evaporimeter, avoid the misoperation of expansion valve, improved the refrigeration of refrigeration system.Simultaneously, also reduce energy consumption, improved the economy of refrigeration plant operation.
2, because this knockout is removable structure, so on two main bodys, the heated time of liquid-dividing head is shorter respectively in the welding of rear and front end copper pipe, oxide skin in its separatory passage is less, its impurity is also less, particularly after welding, before the son of receiving screws, can dispose oxide skin and the impurity of a little substantially, like this, just eliminated the resistance in the separatory passage substantially, so, the described advantage of last point more increased.
3, because the gas-liquid through hole of spool can make the gas-liquid two-phase cold-producing medium fully mix, so, guaranteeing that the gas-liquid two-phase refrigerant mixed is even, promptly reach under the precondition of even equivalent separatory effect, the volume of this knockout can dwindle relatively, its manufacturing cost is relatively low, and when particularly using in central air conditioning equipment, this advantage is especially outstanding.
4, since this split type be that the spool of removable knockout is removable, so the aperture of gas-liquid through hole is variable, in practice, can be according to the variation of operating mode and service condition, knockout is done allotment adaptively, so the compatibility of this knockout is better.
5, as improving, this knockout also can comprise the fixed head of being located at the liquid-dividing head outside, fixed head can be fixed on the metal sheet of evaporimeter, thereby overcome because the inner phenomenon that produces the cold-producing medium turbulent flow of evaporation coil has been avoided in the mobile slow-action and the resonance that evaporation coil is produced of cold-producing medium.
As further improvement, the aperture of described gas-liquid through hole can be 1～3mm, and like this, the uniformity of gas-liquid two-phase refrigerant mixed is better.
As further improving, the profile of described spool can be square, like this, more saves valve core material again.
