Description
Technical field
The utility model relates to a kind of integrated multifunction hydraulic element simultaneously possessing isolation break-make, overflow pressure limiting, reflux pressure letdown effect.
Background technique
In order to reach Quick-pressurizing in hydraulic control system, overflow pressure limiting, the object of reflux pressure letdown, need to use 2/2-way normally open solenoid valve in hydraulic system, pressure limiting relief valve, 2/2-way normal off solenoid valve could form so the complete hydraulic regulation block of hydraulic control system to needs adjustment and carry out hydraulic control, before solenoid valve action, hydraulic oil arrives hydraulic regulation block from liquid entering hole through 2/2-way normally open solenoid valve, Quick-pressurizing can be carried out to regulating block, after hydraulic pressure in regulating block reaches target hydraulic, hydraulic oil flows out through relief valve, thus the hydraulic pressure in guarantee regulating block keeps stable, when needing to reduce the hydraulic pressure in hydraulic regulation block, after solenoid valve action, the action of 2/2-way normally open solenoid valve transfers disconnection to by often opening, the action of 2/2-way normal off solenoid valve transfers connection to by normal off, hydraulic pressure in hydraulic regulation block enters fuel tank by the 2/2-way normal off solenoid valve transferring connection to, thus reach the object of pressure release, in order to the hydraulic control system volume controlling to be made up of discrete hydraulic element to the hydraulic pressure in hydraulic regulation block is large, costly, system complex, therefore invention one can integrated Quick-pressurizing, overflow pressure limiting, the multi-functional hydraulic element in one of reflux pressure letdown necessitate.
Model utility content
The purpose of this utility model is to design a novel multifunction hydraulic element simultaneously possessing Quick-pressurizing, overflow pressure limiting, reflux pressure letdown effect.
The technical solution adopted in the utility model is:
A kind of integrated multifunction hydraulic element, described hydraulic element comprise yoke, valve body, spool and dual face seals seat, described yoke inside is provided with electromagnetic coil, described electromagnetic coil inside is provided with dynamic iron, described dynamic iron is connected with secured core, described secured core and valve core chamber are provided with return spring, described valve body is provided with liquid entering hole successively near electromagnetic coil end, seal ring I, hydraulic regulation mouth, seal ring II, pressure relief opening, seal ring III, described mouth dual face seals seat center hole is communicated with hydraulic regulation mouth, side connects with spool, opposite side is provided with steel ball, described spool small end face connects with steel ball, large end face is connected with dual face seals seat side, described steel ball is connected with overflow spring.
Advantage of the present utility model: design concept is novel, manufacture and easy to use, assembly outward appearance can change the mentality of designing of domestic hydraulic control system, improve the performance of domestic hydraulic element, reduce that discrete hydraulic element part is various, the situation of processing trouble, not high, the unstable properties of up-to-standard rate simultaneously, reduce the manufacture cost of hydraulic control system, improve the technology capability of hydraulic element processing, the Quick-pressurizing of integrated multifunction hydraulic element, overflow pressure limiting, reflux pressure letdown function using effect are good, steady quality.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation before the utility model action;
Fig. 2 is the structural representation after the utility model action.
Wherein: 1, electromagnetic coil; 2, liquid entering hole; 3, seal ring I; 4, hydraulic regulation mouth; 5, seal ring II; 6, pressure relief opening; 7, seal ring III; 8, yoke; 9, dynamic iron; 10, return spring; 11, secured core; 12, valve body; 13, spool; 14, dual face seals seat; 15, steel ball; 16, overflow spring.
Embodiment
As Fig. 1, shown in 2, a kind of integrated multifunction hydraulic element, described hydraulic element comprise yoke 8, valve body 12, spool 13 and dual face seals seat 14, described yoke inside is provided with electromagnetic coil 1, described electromagnetic coil inside is provided with dynamic iron 9, described dynamic iron is connected with secured core 11, described secured core and valve core chamber are provided with return spring 10, described valve body is provided with liquid entering hole 2 successively near electromagnetic coil end, seal ring I 3, hydraulic regulation mouth 4, seal ring II 5, pressure relief opening 6, seal ring III 7, described mouth dual face seals seat center hole is communicated with hydraulic regulation mouth, side connects with spool, opposite side is provided with steel ball 15, described spool small end face connects with steel ball, large end face is connected with dual face seals seat side, described steel ball is connected with overflow spring 16.
As shown in Figure 1, before solenoid valve action, under return spring effect, dynamic iron and spool are to left movement, thus the left side of spool and dual face seals seat is logical, hydraulic oil enters hydraulic regulation mouth from liquid entering hole through dual face seals seat, Quick-pressurizing can be carried out, after the hydraulic pressure in hydraulic regulation mouth reaches target hydraulic, although the right side of steel ball and dual face seals seat seals, but after hydraulic pressure exceedes target hydraulic value, hydraulic oil is through pushing steel ball open, overflow is flowed out, thus the hydraulic pressure in guarantee regulating block keeps stable, when needing to reduce the hydraulic pressure in hydraulic regulation mouth, solenoid valve action, as shown in Figure 2, under the effect of electromagnetic force, dynamic iron and spool overcome return spring active force and move right, seal on the left of spool and dual face seals seat, liquid entering hole and hydraulic regulation mouth cut off, push steel ball open simultaneously, dual face seals seat and steel ball no longer seal, hydraulic pressure in hydraulic regulation mouth enters fuel tank by the right openings of dual face seals seat, thus reach the object of pressure release.
The utility model design concept is novel, manufacture and easy to use, assembly outward appearance can change the mentality of designing of domestic hydraulic control system, improve the performance of domestic hydraulic element, reduce that discrete hydraulic element part is various, the situation of processing trouble, not high, the unstable properties of up-to-standard rate simultaneously, reduce the manufacture cost of hydraulic control system, improve the technology capability of hydraulic element processing, the Quick-pressurizing of integrated multifunction hydraulic element, overflow pressure limiting, reflux pressure letdown function using effect are good, steady quality.
