Process is realized using this area conventional technology, such as can be realized by the way of wire communication or wireless telecommunications,
Its principle and technology are well known to those skilled in the art, be will not be described here.
In pressure assignment component, with pressure setting spring 45, pressure setting spring on the valve body of pressure setting valve 42
45 valve bodies that valve 42 is set to pressure apply spring force, promote pressure setting valve 42 to close, and spring 45 is set by adjusting pressure
The Opening pressure of pressure setting valve 42 can be determined, the Opening pressure is the I shelves pressure that accumulator 24 supplies；
Further, in order to which the flow under corresponding different pressures exports demand, also set on the valve body of pressure setting valve 42
Pressure setting end 49 is put, pressure setting end 49 could be arranged to can be with one of applying power on the valve body of pressure setting valve 42
The form in region；The spring force and can be made by the hydraulic coupling of the pressure setting application of end 49 that so pressure setting spring 45 applies
With on valve body so that valve body towards closing direction move, in order to control by pressure set end 49 apply hydraulic coupling with
Control pressure sets the Opening pressure of valve 42, i.e. II shelves pressure, is also provided with pressure switching valve 43, II shelves pressure ratio I shelves pressure
Greatly.
Pressure switching spring 46 is provided with the valve body of pressure switching valve 43, pressure switches spring 46 towards causing pressure to cut
The direction for changing the closing of valve 43 is biased power；
Auxiliary pump 41 is applied to pressure by pressure switching valve 43 and set to the supply pressure of pressure switching valve 43 oil, the pressure oil
On the valve body for determining valve 42, band dynamic pressure sets valve 42 and moved towards closing direction；Auxiliary behaviour is additionally provided with pressure switching valve 43
Make part 48, control pressure switching valve 43 can be carried out by other means；
Automatically controlled proportional throttle valve 40 is provided with pipeline between pressure switching valve 43 and pressure setting end 49, its is main
For controlling the flow from pressure switching valve 43, avoid producing excessive impact to pressure setting end 49.
Second overflow valve 44 is used as safety valve, and the operating pressure of the second overflow valve 44 is set by overflow spring 47；
Also include adjusting knob 13 in the control panel, adjusting knob 13 is connected with corresponding pointer, pointer instruction
Corresponding scale；Adjusting knob 13 passes through control unit with the automatically controlled end of automatically controlled proportional throttle valve 40 and regulating part driving structure 11
Divide electrical connection；
In practical operation, when needing that the flow velocity between I shelves flow velocity and II shelves flow velocitys is adjusted, then it can pass through
Rotation of adjustment knob 13 realizes that, when rotation of adjustment knob 13, corresponding electric signal can be delivered to automatically controlled proportional throttle valve 40
Automatically controlled end, so that the amount of restriction of automatically controlled proportional throttle valve 40 is increased or subtracted with the rotation of rotation of adjustment knob 13
Small, so, the size of the pressure acted on pressure setting end 49 can also produce change, so as to ease up in quick I shelves flow velocity
The speed of corresponding flow velocity can be easily adjusted between slow II shelves flow velocitys, meanwhile, regulating part driving structure 11 will can also be poured
The size of muzzle regulating part 9 is adjusted correspondingly, to limit the conjunction between the first aperture position and the second aperture position
Suitable aperture position, with corresponding flow matches.So, you can rapidly to set " I shelves flow velocity " or " II shelves flow velocity ",
Flow velocity between " I shelves flow velocity " and " II shelves flow velocity " can also be adjusted.
Relative to prior art, the beneficial effects of the present invention are：
1st, the flow for entering cast gate can be adjusted by operating on the control panel, without live interim adjustment heat
The bore or shape of runner, it is easy to operate simple, do not waste time and energy；
2nd, the quantity for the pipeline being connected with hot flow path is reduced, it is easy to adjust, the production time has been saved, has improved production effect
Rate, the complexity of production is reduced, advantageously reduces cost.
