Description

The electric expansion valve that a kind of multichannel is divided equally
Technical field
The present invention relates to a kind of expansion valve, more particularly to the electric expansion valve that a kind of multichannel is divided equally.
Background technology
In ice cube ice making equipment, there is a situation where that ice making mould is made up of multiple paths, in ice-making process, pass through pressure The refrigerant of contracting machine pressurization is condensed within the condenser, is sent to expansion valve by reservoir, the system after being depressurized by expansion valve Cryogen, coolant flow divider is sent to by refrigerant piping, is shunted in refrigerator current divider, ice making is sent to afterwards Multiple paths of mould, low pressure refrigerant is back to compressor after ice making mould has gasification.So circulation, refrigerant is swollen After swollen valve is depressurized, the referred to as biphase gas and liquid flow refrigerant of low pressure is flowed into after current divider, the biphase gas and liquid flow refrigerant, even Connect expansion valve and coolant flow divider is easily changed into bolt stream and plug flow containing a large amount of bubbles when matching somebody with somebody Bottomhole pressure.Producing such as In the case of as described above, bubble can not be uniformly flowed into an individual isocon of isocon mounting hole, it is difficult to uniform Shunting.
The content of the invention
For above-mentioned produced problem, it is an object of the invention to provide the electric expansion valve that a kind of multichannel is divided equally, this is swollen Swollen valve arrangement is simple and convenient to operate, and eliminates the structure design from expansion valve to current divider loop so that the expansion valve machine is played Throttling action, has uniform shunting action, improves the accuracy of shunting, reduce production cost again.
To reach above-mentioned purpose, technical scheme is as follows:
The electric expansion valve that a kind of multichannel is divided equally, including valve body, be arranged on the valve body admission inlet, be arranged on institute State multiple shuntings outlet, the valve pocket being arranged in the valve body and the refrigeration being arranged in the valve body on valve body Agent logical circulation road, the valve pocket is connected with the admission inlet and shunting outlet respectively by the cold-producing medium stream path, The downstream of the cold-producing medium stream path flow to the shunting exit and separated by the first valve body being arranged in the valve body, institute Each described shunting exit of correspondence on the first valve body is stated to be provided with the first valve opening, first valve opening provided with the valve coordinated with it Core, forms first throttle portion between the valve element and first valve opening, the valve element is provided with drive division, the drive division energy The valve element is driven to be retreated relative to first valve opening simultaneously, to change the aperture in the first throttle portion.
In the above-mentioned technical solutions, refrigerant is flowed into valve pocket through admission inlet, drive division effect, while control is each The upper corresponding valve element in shunting outlet so that valve element is retreated to change opening for each first throttle portion relative to the first valve opening Spend, pressure all same of the refrigerant in valve pocket in each restriction so that it enters the first valve opening by first throttle portion Flow is consistent, and first throttle portion carries out throttling gasification to refrigerant, and can also be operated according to flow and freezing load etc. Situation, suitably adjusts throttling degree, further improves the bifurcated characteristic of cold-producing medium stream, is retreated while each valve element, it is ensured that Shunting is uniform, and automaticity is high, reduces cost.
As the preferred of above-mentioned technical proposal, the first throttle portion is by the valve element relative to first valve opening Valve seat is retreated can be fully closed, and first throttle portion size can be adjusted by adjusting spool, appropriate regulation throttling degree.
As the preferred of above-mentioned technical proposal, the valve body also includes cooperatively forming the valve pocket with first valve body The second valve body.Second valve body is attached by bolt with the first valve body, and plays sealed effect.
As the preferred of above-mentioned technical proposal, the valve element is in pole shape, and its front end is throttling action portion, and pars intermedia is company Socket part, the connecting portion is connected on second valve body, and rear end is the installation portion of the drive division and stretches out second valve Body.
As the preferred of above-mentioned technical proposal, in the inner peripheral surface of the outer peripheral face in the throttling action portion and first valve opening At least one party towards the valve element front end formed cone-shaped.Therefore, when the aperture in first throttle portion reduces, easily bite Foreign matter, when aperture become it is big when, foreign matter can be easily washed away by refrigerant, so according to the structure, can with the blocking of surface foreign matter, The problems such as valve element action is bad will not be produced.
As the preferred of above-mentioned technical proposal, the inner peripheral surface of the outer peripheral face in the throttling action portion and first valve opening is all Cone-shaped is formed towards the front end of the valve element.
As the preferred of above-mentioned technical proposal, the bevel angle of the inner peripheral surface of the outer peripheral face of the valve element and first valve opening Degree is identical.The effect that will be segmented in refrigerant can so be given full play to.
As the preferred of above-mentioned technical proposal, the upstream of the cold-producing medium stream path is corresponding every on first valve body Individual first throttle portion is provided with the second restriction, and second restriction is provided with to the cold-producing medium stream path in the first throttle portion Space enlargement portion, second restriction along the first next door being disposed adjacent by forming, and first next door is pointed to and stretched to In the valve pocket.So, the second restriction can give full play to the effect for the flow velocity variation and pressure oscillation for suppressing refrigerant, pass through Second restriction is refined to refrigerant, due to by the refrigerant in valve pocket Direct spraying, so improving cold-producing medium stream Diverting feature, in addition, expansion space part dissipates the ejection energy of cold-producing medium stream, gas in the refrigerant to flowing into first throttle portion Bubble is further segmented.
As the preferred of above-mentioned technical proposal, the drive division includes driving link, driven member and drives the driving link The force piece of motion, the driving link is connected on the 3rd valve body, and the driven member is connected to the installation portion of the valve element, described Force piece drives driving link motion, and driving link drives driven member motion, and the driven member band movable valve plug is relative to described the The valve seat of one valve opening is retreated can be fully closed.
As the preferred of above-mentioned technical proposal, the driving link is driving gear, and the driven member is driven gear, described Force piece is asynchronous machine.So, drive division ensure that the motion of each valve element is consistent, so that convenient control first throttle portion Aperture, controls throttling degree.
The invention has the advantages that:The present invention is simple in construction, easy to operate, eliminates from expansion valve to current divider The structure design in loop so that the expansion valve machine plays throttling action, has uniform shunting action, improves the standard of shunting again True property, reduces production cost.
