Specific embodiment
The following is specific embodiments of the present invention and with reference to attached drawing, technical scheme of the present invention is further described,
But the present invention is not limited to these embodiments.
Technical solution provided by the invention is illustrated in more detail with reference to Fig. 1.
As shown in Figure 1, there is the pressure-control valve of pooling feature to include for this：
Valve body 10 is equipped with B mouthfuls, T mouthfuls and the P mouths for oil inlet on valve body 10, spring cavity is provided in valve body 10
11, X mouthfuls are equipped at spring cavity 11, overflow valve is connected at X mouthfuls, damping hole is additionally provided on valve body 10；
Spool 20 is axially plugged in 10 middle part of valve body and connects with spring cavity 11, and the spool 20 is equipped with and spring cavity
The throttle orifice of 11 connections.
In the present invention, integral structure layout is compact, and 20 one end of spool is sealed in by plug screw 30 in valve body 10, the other end
Connect with spring cavity 11, and throttle orifice is opened in the end that spool 20 and spring cavity 11 connect；Choke plug is equipped on valve body 10
First 40, the damping hole is set at throttling plug 40.
Sealing is inserted with adjustment seat 50 on valve body 10, and the spring cavity 11 is surrounded and formed by adjustment seat 50 and valve body 10,
Adjusting screw rod 60 axially is equipped at 50 middle part of adjustment seat, the part that adjustment seat 50 is stretched out in adjusting screw rod 60 is equipped with nut
70, it is easy to adjust；It is docked by spring 80 and spool 20 part that adjusting screw rod 60 stretches into spring cavity 11；The spool 20 passes through
Spring base 90 stretches into spring cavity 11, and the spring 80 is socketed in outside spring base 90.
The present invention protects a kind of pressure-control valve with pooling feature, is a kind of remote-control pressure control valve, overall structure
It is compact, it is simple to manufacture, the stagnant ring of small, light-weight and pressure is small, and the present invention can pass through the spring cavity 11 of this valve of remote control
Pressure realizes the output of the outlet pressure of hydraulic pump and flow, to reach the energy-efficient effect of hydraulic system, specifically, when this hair
When on hydraulic pump, P mouthfuls, B mouthfuls, T mouthfuls are connected respectively with the oil outlet of hydraulic pump, variable plunger shaft, oil back chamber, work as pump for bright use
Pressure oil enters P mouthfuls, and pressure oil is acted on 20 right side of spool, at the same pressure oil by the throttle orifice m2 on spool 20 into
Enter, spring cavity 11 is acted on 20 left side of spool, since 20 or so active area of spool is equal, pressure is equal, in spring 80
Under the action of spool 20 remain stationary as, B mouthfuls connect with T mouthfuls, are equivalent to hydraulic pump variable plunger shaft and are connected with oil back chamber, variable live
Fill in chamber no pressure, the hydraulic pump amount of remaining unchanged, system application in X mouthful by connection one overflow valve, to 11 pressure of spring cavity
Carry out remote control.
After the pressure of spring cavity 11 is reduced to preset value, when 20 right side active force of spool adds more than left side active force
The sum of spring force, to moving to left, P mouthfuls are connected spool 20 with B mouthfuls, and B mouthfuls disconnect with T mouthfuls, pressure oil entering variable plunger shaft, driving pump
Stroking mechanism variable changes pump output flow and stablizes in flow status needed for system, while the pressure oil of entering variable piston
By a damping hole m1 shunting parts to oil back chamber, to play variable cushioning effect.
Conversely, by the overflow valve of X mouthfuls of remote adjustment, 11 pressure of spring cavity is improved, spool 20 is made to move right, P mouthfuls and B
Mouth disconnects, and B mouthfuls connect with T mouthfuls, variable plunger shaft oil return, and pump stroking mechanism reset makes pump be restored to maximum stream flow state.
In conclusion the present invention, to meet hydraulic system requirement, can simultaneously be reached with remote control prexxure of the hydraulic pump, flow
To energy-saving effect.
