Description
Technical field
The utility model relates to Electromagnetic Control technical field, specifically relates to the solenoid valve controlling refrigerant break-make.
Background technique
In Electromagnetic Control technical field, mortor operated valve is widely used as Automatic Control Component.Solenoid valve be by electromagnetic coil come control system medium break-make, adjustment MEDIA FLOW to the valve with flow.
Fig. 1 is the structural representation of existing a kind of solenoid valve, comprises valve body 1 ' and electromagnetic coil 2 ', and valve body 1 ' is fixedly connected with by bolt assembly 3 ' with electromagnetic coil 2 '.The encapsulated layer 4 ' that electromagnetic coil 2 ' comprises skeleton 21 ', is wound on the enameled cable winding 22 ' on skeleton 21 ' and skeleton 21 ' and winding 22 ' is encapsulated in wherein, also comprises and is coated on the outside magnet case 5 ' of encapsulated layer 4 '.
As shown in Figure 1, one sealing O type circle 6 ' is installed between bolt assembly 3 ' and magnet case 5 ', by bolt assembly 3 ' is compressed relative to magnet case 5 ', O type circle 6 ' is out of shape, to make O type circle 6 ' play seal action, thus the impurity such as the moisture in the external world can not infiltrate from the gap between bolt assembly 3 ' and magnet case 5 '.
But also there is following deficiency in this solenoid valve: the impurity such as extraneous moisture also can by the gap in the gap 7 ' between the outer wall of the gap inflow skeleton 21 ' between magnet case 5 ' and the sleeve of valve body 1 ' and the outer wall of valve body 1 ' and between the inwall of magnet case 5 ' and the outer wall of encapsulated layer 4 '.Further, the most serious with the moisture accumulation in gap 7 '.Therefore, when product is used in moist ice-cold rugged environment, the moisture infiltrating gap 7 ' is more.When the ambient temperature in the external world is lower than zero degree, and during coil blackout, the moisture be gathered in gap 7 ' build-ups ice eventually, because the density of the density ratio water of ice is little, therefore, now the volume of ice is 1.1 times of the volume of original water, and the outer wall of coil rack will be subject to the extruding force produced because of the volumetric expansion of ice; When coil electricity works, due to the rising of temperature, ice is melted into water again, and extruding force disappears again.And so forth, skeleton easily ftractures.And skeleton is once cracking, moisture can enter again other parts of electromagnetic coil, causes the electric insulation of electromagnetic coil bad, causes electromagnetic coil to lose efficacy.In addition, due to the invasion of the middle moisture in gap 7 ', skeleton 21 ' easily sticks together with the sleeve of valve body 1 ', causes electromagnetic coil not easily to be removed, and the maintenance of this market to later product brings very big inconvenience.
