Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified.
As shown in Figure 1, a kind of overlapping ratio electromagnetic flow valve has valve body 1; Has valve pocket 5 in the valve body 1; Valve pocket 5 ends are equipped with pressure regulation blind nut 2, and valve pocket 5 inside are equipped with push rod 3, relief pressure valve cartridge 4, pressure adjusting spring 16, main valve plug 6 and Regulation spring 11, and main valve plug 6 inside are equipped with needle-valve 7 and needle valve spring 12; Described valve body 1 is equipped with proportion electro-magnet 8 near Regulation spring 11 1 ends; The spool end of proportion electro-magnet 8 is equipped with electromagnet cartridge cover 10, and first seal ring 9 is equipped with at the position that contacts with valve body 1 on the proportion electro-magnet 8, and valve pocket 5 outsides are equipped with second seal ring 13, the 3rd seal ring 14 and the 4th seal ring 15 respectively.
The described overlapping ratio of the utility model embodiment electromagnetic flow valve has A, B, P, four passwaies of T; They communicate with other Sandwich plate valve is corresponding up and down respectively; When the P mouth is Sandwich plate valve pressure oil passage, this overlapping of pressure oil input ratio electromagnetic flow valve P mouth, and through the aperture of valve pocket 5 high order ends and aperture these normal open walk entering relief pressure valve cartridge 4 right side cavitys and main valve plug 6 left side cavitys of relief pressure valve cartridge 4; Because Regulation spring 11 is between valve pocket 5 and main valve plug 6; The pressure of Regulation spring 11 is pushed main valve plug 6 to the right all the time, withstands on the electromagnet cartridge cover 10, at this moment aperture on main valve plug 6 left side and the dislocation of the aperture on valve pocket 5 left side; The hydraulic oil of P mouth can not pass main valve plug 6 and valve pocket 5 flows into the P1 mouth, so the ratio electromagnetic throttle valve is in closed state.When proportion electro-magnet 8 was started working, its thrust overcame pressure and Regulation spring 11 pair main valve plugs 6 to the right the pressure of hydraulic oil to main valve plug 6 left sides, with main valve plug 6 progressively to left translation.When the aperture on aperture on main valve plug 6 left side and valve pocket 5 medial side begins to connect; The hydraulic oil of P mouth begins to pass main valve plug 6 and valve pocket 5 flows into the P1 mouth; Along with main valve plug 6 constantly to left translation, the aperture on main valve plug 6 left side is communicated with area with aperture on valve pocket 5 left side and progressively increases, the hydraulic oil that the P mouth flows into the P1 mouth also progressively strengthens; Therefore the control ratio current of electromagnet just can be controlled the flow size of Sandwich plate valve, reaches the purpose of control flow rate.
Hydraulic oil at the P mouth flows in the process of P1 mouth; Relief pressure valve cartridge 4 is moved to the left under the thrust of the pressure oil that constantly increases; When the aperture in the middle of the relief pressure valve cartridge 4 moves past the aperture of valve body 5 high order ends; The normal open walk that the P mouth flows into the P1 mouth diminishes until being cut off, and the oil pressure of P1 passage no longer raises, and pressure is defined.When if the oil pressure of P mouth passage is lower than pressure limiting setting numerical value; Relief pressure valve cartridge 6 right-hand member pressure reduce; Relief pressure valve cartridge 4 moves right under the thrust of pressure adjusting spring 16, and the aperture of relief pressure valve cartridge 4 peripheries is connected with the aperture of valve pocket 5 left ends again, and the hydraulic oil of P mouth can get into the cavity of relief pressure valve cartridge 4 and main valve plug 6 again; P1 passage and P passage are switched on again, and the oil pressure of P1-P passage is reached unanimity again.Turn pressure regulation blind nut 2 can pass through pressure adjusting spring 16 and push rod 3, relief pressure valve cartridge 4 left sides is produced different pressure, thereby the oil pressure of P1 passage is limited to below a certain control numerical value.
And the effect of needle-valve 7 and needle valve spring 12 is: when proportion electro-magnet 8 is not worked; Main valve plug 6 is in normally off with valve pocket 5; The pressure oil of P mouth produces pressure through the aperture in the middle of main valve plug 6 left sides to needle-valve 4 left sides; If this pressure is greater than the pressure on 12 pairs of needle-valve 7 right sides of needle valve spring, needle-valve 7 will move to right, and the P mouth can be walked around needle-valve 7 entering main valve plugs 6 right sides by a spot of pressure oil; And the aperture on main valve plug 6 right edge and the aperture on valve pocket 5 right edge get into T1 mouth passage, plays earial drainage and backflow effect.When proportion electro-magnet is started working; P mouth and P1 mouth begin to connect; When flow continues to increase; The a spot of pressure oil of P mouth also can get into T1 mouth passage, this can reduce P mouth and P1 mouth when connecting, and the pressure transient change makes the pressure oil of throttle valve P1 passage that stability preferably arranged in flow process to the impact of oil hydraulic circuit.Thereby make overlapping ratio electromagnetic flow valve no matter all can reduce the hydraulic pressure fluctuation when being low pressure or during high pressure, play the current stabilization effect.
First seal ring 9 is assembled in proportion electro-magnet 8 bottoms of the described overlapping ratio of the utility model embodiment electromagnetic flow valve; Valve pocket 5 outsides are assembled three seal rings 13,14 respectively; 15 can be enclosed in overlapping ratio electromagnetic flow valve pressure inside oil the inside of valve effectively, prevent that hydraulic oil from leaking.
