Description
Technical field:
The utility model relates to a kind of valve gap male-type hydraulic cartridge valve, especially for the valve gap male-type hydraulic cartridge valve equipment in the high-volume hydraulic system circuit.
Background technique:
At present, hydraulic cartridge valve of the prior art, because structural limitations, oil filling capacity is little, the differential pressure flow characteristic is poor, cause system temperature too high easily, the pressure loss is big, influences system working life, because the height of pick-and-place components and the degree of depth of valve opening are not easy to guarantee quality of fit, also just can not guarantee the seal compression of Sealing, be to adopt end face seal between pick-and-place components and the control cover plate, and after oily temperature rise, Sealing is easy to occur aging, lose sealing effect, and the seepage situation occurs between pick-and-place components and the control cover plate easily.
Summary of the invention:
The purpose of this utility model, provide a kind of valve gap male-type hydraulic cartridge valve, it is to adopt spool is packed in the valve pocket axial bore, the valve pocket upper end is provided with valve gap, valve gap is provided with a convex portion, and the convex portion device is in control cover plate, and between valve gap and spool, Returnning spring is set, after high pressure oil enters valve core inside, owing to be to adopt the cylinder sealing between valve gap and the control cover plate, even the tolerance of the deep processing of valve opening is big, there is not the few problem of seal compression between pick-and-place components and the control cover plate yet, thereby has realized that hydraulic cartridge valve can the long-time high pressure resistant purpose that seepage can not occur.
The utility model valve gap male-type hydraulic cartridge valve takes following technological scheme to realize, it is by valve pocket, spool, valve gap, Returnning spring, control cover plate and solenoid directional control valve constitute, in the valve pocket axial bore spool is set, valve pocket one end is nested with valve gap, between valve gap and the spool Returnning spring is set, the valve gap the other end is provided with projection, the valve gap upper end is provided with control cover plate, the valve gap convex portion is nested with in control cover plate, be provided with in the middle of the control cover plate in the middle of the logical valve gap of oil circuit, control cover plate is provided with the logical control port of oil circuit, control cover plate is provided with the logical return opening of oil circuit, the control cover plate side is provided with solenoid directional control valve, and valve gap convex portion and control cover plate mating part are provided with first seal ring, and valve pocket and valve gap mating part are provided with second seal ring.When the solenoid directional control valve no electric circuit, high-voltage oil liquid enters control port and arrives solenoid directional control valve promotion electromagnetic switch valve core by oil circuit, arrives spool through oil circuit in the middle of the control cover plate, and spool is closed during use; When solenoid directional control valve was switched on, the high pressure oil in the spool entered return opening through oil circuit and the solenoid directional control valve in the middle of the control cover plate, and spool is opened.
The effect of the utility model valve gap male-type hydraulic cartridge valve is simple in structure, and easy to operate, volume is little, and cost is low, the cylinder sealing, high pressure resistant non-leakage, realize commutation function, aesthetic in appearance, the pressure loss is little, and is multiple functional, safe and reliable, is widely used in all kinds hydraulic cartridge valve system.
Description of drawings:
The utility model valve gap male-type hydraulic cartridge valve will describe in further detail in conjunction with the accompanying drawings.
Accompanying drawing is the structural representation of the utility model valve gap male-type hydraulic cartridge valve.
