Description
Technical field
The present invention relates to the electric drive valve of a kind of mortor operated valve and solenoid valve etc., particularly relate to a kind of electric drive valve being suitable for using in the refrigeration cycle of refrigerant circulation.
Background technique
As the mortor operated valve of one of the electric drive valve used in the refrigeration cycle of refrigerant circulation, there is such as such described in patent documentation 1,2 mortor operated valve, it has: screwfeed mechanism, and this screwfeed mechanism utilizes the rotation of rotor and spool is contacted with valve seat, leaves; And plastic stop mechanism (movable stop, fixed stop), the movable range of this stop mechanism determination spool.
In the mortor operated valve of the 1st form, be configured with screwfeed mechanism, it comprises: retaining thread portion (external thread part), and this retaining thread portion is formed in the periphery of the guide sleeve being fixed on valve body; Mobile screw section (internal thread part), this internal thread part is formed in the inner circumferential with the valve shaft retainer of rotor one, when rotor being rotated when utilizing this screwfeed mechanism to a direction, this rotor and just such as rotate with the valve shaft retainer of its one and decline, with this, valve shaft and the spool being located at its lower end also just decline, by making spool change relative to the lift amount (=valve opening) of valve seat, thus adjust refrigeration agent pass through flow.
In addition, said electric valve is, between valve shaft retainer and valve shaft, compression is provided with all the time by valve shaft (valve closing direction) compression helical spring of being exerted a force downwards.This compression helical spring to improve the closedown (sealing) between them relative to the interface pressure of valve seat (valve port) to improve spool and arrange to cushion with.
In the mortor operated valve of above-mentioned 1st form, when making rotor and valve shaft retainer continuous rotation declines, spool is just pressed against on valve seat, and valve port is closed.In this moment, the movable stop being located at valve shaft retainer does not also touch the fixed stop being located at valve body side (guide sleeve), spool will valve port close state under, valve shaft retainer further rotates decline.Now, because valve shaft retainer declines relative to valve shaft, therefore, above-mentioned helical spring compresses, and absorbs the down-force (force) of (decay) valve shaft retainer thus.Then, when valve shaft retainer declines further, movable stop touches fixed stop, even if continue the energising (pulse supply) carried out stator, the decline of valve shaft retainer is also forcibly stopped, and the position of valve shaft retainer is now in most lowering position.
So, spool is pressed against on valve seat, and after valve port is closed, valve shaft retainer also declines, and helical spring is compressed.
On the other hand, in the electric drive valve in the past used at refrigerator, air conditioner, under full-shut position, when refrigeration agent does not flow completely, the slide part that the machine oil (lubricant oil) be mixed in refrigeration agent is not just supplied to compressor grades, and likely produces the unfavorable condition of compressor sintering etc.Therefore, in order to prevent this situation, such as patent documentation 3 can be seen, has the mortor operated valve of the 2nd form, is formed with cut-in groove etc. at valve seat, even the state of valve land on valve seat (valve closing state), a small amount of refrigeration agent also can flow.
In addition, in recent years, in order to improve energy saving, even need a kind of tiny flow quantity also can carry out the mortor operated valve of highi degree of accuracy control, in the occasion of the precise hard_drawn tuhes that must carry out with this tiny flow quantity, sometimes use and do not make valve land on valve seat, that is, the mortor operated valve of or not 3rd form of valve closing.In the mortor operated valve of the 3rd form, under small aperture state before valve land, that open a little, make movable stop touch fixed stop, do not become full-shut position, refrigeration agent flows from the spool after opening a little and the gap between valve seat.
In addition, even if in the mortor operated valve of the 3rd form, between valve shaft retainer and valve shaft, also compression is provided with all the time by valve shaft (valve closing direction) compression helical spring of being exerted a force downwards, and this helical spring is different from the helical spring in the mortor operated valve of the 1st form, just force mild degree does not leave valve shaft to valve shaft retainer.

Patent documentation 2: Japanese Patent Laid-Open 2013-122281 publication
Patent documentation 3: Japanese Patent Laid-Open 11-51514 publication
Electric drive valve in the past, especially in the mortor operated valve of the 3rd form not carrying out valve closing, has following problem.
Namely, in the mortor operated valve of the 1st form in the past, when movable stop touches fixed stop, when the rotation decline of valve shaft retainer is forcibly stopped, helical spring is compressed, obtain consequent cushioning effect, but in the mortor operated valve of the 3rd form, because spool is not landed on valve seat, therefore, the compression helical spring be installed between valve shaft retainer and valve shaft can not be compressed further, cushioning effect as described above can not be obtained, the former is large for the touching energy Ratios of movable stop touching fixed stop, sometimes resinous two retainers can produce wearing and tearing.
If retainer produces wearing and tearing, then the touch position of movable stop and fixed stop just produces deviation, produce the deviation etc. of basic point, and correctly can not carry out the flow adjustment of small guide vane, and in addition, not only this mortor operated valve, comprise the equipment class of the compressor be disposed in refrigerant circuit etc., also sliding parts can be made because of abrasion powder to produce wearing and tearing, or produce blocking, thus have constituent part easily to produce the problem of the bad or fault of the action of locking etc.
