Technical field
The utility model relates to a kind of two-way plug-in valve, especially relates to a kind of mangetic core assembly for the pilot-type two-port cartridge valve.
Background technique
In prior art, common pilot-type two-port plug-in mounting combination valve is comprised of pilot valve, one-way valve, cartridge valve, guides the action of cartridge valve by the action of pilot valve.The deficiency of this structural type is integrated inadequate, and the join dependency external pipe between each valve connects, not only bulky, and pipeline flow resistance is large, crushing is large, because tie point too much causes the possibility of seepage, also greatly increases; Another deficiency is that the cartridge valve structure is owed rationally, and the nonstandard groove of valve inner is many, cause the processing technology complexity, and cost of production is too high, demand that can not satisfying the market.For adapting to the demand in market, the inventor develops the valve cover structure of the pilot-type two-port plug-in mounting combination valve that integrated degree is high, for adapting to this variation, the mangetic core assembly of two-way plug-in valve is improved.
The model utility content
The purpose of this utility model is to provide a kind of rational in infrastructure, universal mangetic core assembly for the pilot-type two-port cartridge valve for the prior art deficiency.
The purpose of this utility model is to realize by following measures: a kind of mangetic core assembly for the pilot-type two-port cartridge valve, and mangetic core assembly comprises spool, valve core housing, lining, it is characterized in that, wherein:
Described valve core housing is cylindric hollow cylinder, the front end of hollow cylinder outer rim and valve body contact position is provided with on axle journal, axle journal and is evenly equipped with some oil-feed through holes, the annular that is provided with hollow cylinder outer rim and valve gap contact position derives the oil duct oil groove, reaches annular oil discharge passage oil groove, annular derives on oil duct oil groove, annular oil discharge passage oil groove and is evenly equipped with respectively some through holes, the hollow cylinder inner chamber is the large small cylindrical surface of the concentric for the spool insertion, and the outlet of hollow cylinder inner chamber small cylindrical surface is corresponding with the valve body oil outlet;
Described spool is the Cylindrical object that stage casing is shaft shoulder shape, the shaft shoulder shape outer rim of spool is corresponding with the great circle cylinder of valve core housing inner chamber, the Cylindrical object cylinder of spool shaft shoulder shape one side and valve core housing small cylindrical surface coincide, spool shaft shoulder shape opposite side Cylindrical object cylinder leaves annular space with valve core housing, and spool is provided with the cavity for the installation stage clip leaving Yi Ce end, annular space;
Spool inserts in valve core housing, through hole on the derivation oil duct oil groove of spool shaft shoulder shape side and valve core housing is corresponding, lining inserts in the gap of valve core housing and spool, through hole on the oil discharge passage oil groove of valve core housing is corresponding with described gap, some oil-feed through holes at the cylinder cut-off valve core retainer plate axle journal position of the identical side of spool and valve core housing small cylindrical surface.
Described each cylinder of spool Cylindrical object is equipped with some oil grooves.
Compared with prior art, adopted the mangetic core assembly for the pilot-type two-port cartridge valve the utility model proposes, have following advantage: 1) this product coordinates with the valve gap of two-way plug-in valve, improved the integrated degree of existing pilot-type two-port cartridge valve, the control valve core assembly is moved to required oil duct and be integrated in valve gap, reduced the breakthrough of external pipeline joint; 2) improvement of this product structure does not relate to the valve body of original two-way plug-in valve, and the valve body of prior art still can continue to use, and can not cause new waste, has realized the upgrading of product by minimum cost, greatly reduces fabricating cost, receives praises from customers.
The accompanying drawing explanation
Fig. 1 is the example structure schematic diagram the utility model proposes.
Embodiment
Below in conjunction with accompanying drawing, embodiment is elaborated: Fig. 1 shows an embodiment of the present utility model.In figure, a kind of mangetic core assembly for the pilot-type two-port cartridge valve, mangetic core assembly comprises: spool 4, valve core housing 5, lining 6, wherein:
