Abstract
The utility model discloses a dual-chamber load sensing proportional valve, which comprises a valve body and two valve rods provided in the valve body. An oil inlet and an oil outlet are provided on the valve body. The valve body is provided with a balancing assembly at one end of the valve rod. The balancing assembly comprises a valve cap, a compression spring, a balancing base, a balancing plate and a gasket. The balancing assembly of the dual-chamber load sensing proportional valve enables the two valve rods to remain in the same plane, thereby reducing the output pressure difference of the two chambers and further ensuring a greater stability of the dual-chamber load sensing proportional valve.
Description
Technical field
The utility model relates to a kind of two-chamber load sensing valve.
Background technology
At present the balance portion that major part is provided with the load sensing valve of two-chamber on automobile adopts the form of pressing plate, the mounting means of pressing plate can make that pressing plate can be around one spot wobble, therefore two valve rods act on power on the pressing plate when unequal, pressing plate can produce inclination, two valve rod ends are on the Different Plane, cause the output of two chambeies that bigger pressure reduction is arranged, there is potential safety hazard in the instability that works together during driving.
The utility model content
The technical problems to be solved in the utility model provides a kind of two-chamber load sensing valve, and two chambeies output pressure reduction is little, stable performance.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this two-chamber load sensing valve comprises valve body and is located at two interior valve rods of valve body, described valve body is provided with oil inlet and oil outlet, described valve body is provided with the balance assembly at an end of valve rod, described balance assembly comprises valve gap, compression spring, the balance seat, balance plate, pad, described balance plate two ends are pressed in the top of two valve rods respectively, the cross-sectional plane of described balance seat is T-shaped, described balance seat interts in the middle of balance plate, described valve body is provided with groove, described balance seat lower end is arranged in the groove, described balance seat top is provided with pad, and described pad is provided with compression spring, and the cross-sectional plane of described valve gap is stepped appearance, described valve gap is fixedly connected on the valve body, and the top of described valve gap is inner to be connected with compression spring.
As a kind of improvement of the present utility model, described balance plate two ends are provided with the right angle breach.Can better locate valve rod, also be convenient to install.
The utility model adopts technique scheme, and it is in the same plane that the balance assembly of two-chamber load sensing valve can remain two valve rods, makes two chambeies output pressure reduction little, and then guarantees that the two-chamber load sensing valve has the performance than high stable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is the structural representation of a kind of two-chamber load sensing valve of the utility model.
The specific embodiment
As shown in Figure 1, the valve body 8 of two-chamber load sensing valve is provided with a plurality of oil inlets and a plurality of oil outlet, realize make and break process by being located at valve body 8 in-to-in valve rods 1 between each oil inlet and cooresponding with it oil outlet, valve rod 1 bottom is arranged on valve body 8 inside, and the top is towards valve body 8 outsides; Valve body 8 is provided with at valve rod 1 end outwardly and is used to keep two valve rods 1 and is in conplane balance assembly.This balance assembly has comprised valve gap 2, compression spring 3, balance seat 4, balance plate 5 and pad 6.Valve gap 2 is semi-enclosed structure, and its cross-sectional plane is stepped appearance, and the top is smooth structure, it with valve body 8 between be connected by screw retention, thereby compression spring 3, balance seat 4, balance plate 5 and pad 6 are fixed on the valve body 8.Balance plate 5 two ends are provided with right angle breach 9, and balance plate 5 is pressed in the top of two valve rods 1 respectively at these right angle breach 9 places; In the middle of it individual through hole is arranged, the T-shaped balance seat 4 of cross-sectional plane just can be installed.One end of balance seat 4 broads is pressed on the balance plate 5, and its vertically long part then is installed in the groove 7 of valve body 8, and the size of this groove 7 is just vertically coincide than the size of long part with balance seat 4, and balance seat 4 can only be done straight-line motion like this.Over against the top of valve gap 2, compression spring 3 and pad 6 are arranged between balance seat 4 and the valve gap 2 on the top of balance seat 4, and pad 6 is arranged on the balance seat 4, is supporting compression spring 3.Balance seat 4 presses balance plate 5 all the time under the effect of compression spring 3, make balance plate 5 and balance seat 4 be connected as a single entity, because balance seat 4 can only be done straight-line motion under the restriction of groove 7, so balance plate 5 still can maintain on original plane, guarantee that the chamber output pressure reduction at two valve rods, 1 place is very little when being subjected to force unbalance.
