Description of the drawings
Structure chart of the accompanying drawing 1 for the high accuracy proportion adjustment pump of the present invention.
Specific embodiment
High accuracy proportion adjustment pump to the present invention, is described further below in conjunction with the accompanying drawings：
The high accuracy proportion adjustment pump of the present invention, is by pump case 1, piston 2, inlet one-way valve 3, Outlet check valves 4 and stream
Adjustable valve 9 is constituted, and the middle part chamber 12 of described pump case 1 is piston chamber's cylinder body 11, and a side cavity of pump case 1 is mounted with entrance
Pipeline 6 and inlet one-way valve 3, another side cavity are mounted with Outlet check valves 4 and export pipeline 7, and line entry is unidirectional with entrance
Chamber between valve 3 is inlet chamber 13, is middle part chamber between the chamber between inlet one-way valve 3 and Outlet check valves 4, exports single
It is outlet chamber to the chamber between valve 4 and tube outlet.Circulation line 8 in pump case 1 is by middle part chamber 12 and inlet chamber 13
Connection, is mounted with the flow control valve 9 with taper regulating valve stem 10 on circulation line 8.
The tail end of described piston 2 is hinged with connecting rod 16, and the other end of the connecting rod 16 is hinged with crank 15, and crank 15 is fixed
On the output shaft of motor 14.Motor 14 is that piston 2 provides power by linkage, enables piston 2 to move reciprocatingly.
Described inlet one-way valve 3 is entrance pipe 6 to the direction of export pipeline 7 with the forward direction of Outlet check valves 4.I.e.
Mother solution can only be direction from entrance pipe 6 to export pipeline 7 in the circulating direction of within the chamber.
Described flow control valve 9 is installed on the side wall of pump case 1, and the taper regulating valve stem 10 on flow control valve 9 interts
It is actively tied on circulation line 8.Taper regulating valve stem 10 is pyramidal structure, and its purpose one is in order to ensure that seal is good, more
It is important to reduce the shearing to mother solution, make the molecule of mother solution be unlikely to excessively to be broken to small molecule so as to thinning, glue
Degree declines, it is ensured that the quality of mother solution.
Flow control valve 9 can also be able to be to automatically adjust to adjust manually, pacify if manually on flow control valve 9
Dress handwheel or rotary handle etc., are threaded in or out the Flow-rate adjustment of taper regulating valve stem 10 by operating handwheel and rotary handle
Valve 9 reaches the purpose of flow-control；If automatically adjusting, then effusion meter 5, effusion meter 5 and stream need to be installed on export pipeline 7
Adjustable valve 9 is connected with control system circuit respectively makes effusion meter 5, control system, flow control valve 9 constitute closed loop control electricity
Road.Flow parameter feedback is read at any time by effusion meter 5 carries out real-time adjustment to flow control valve 9 reaching control mother liquid flow rate
Purpose.
The high accuracy proportion adjustment pump actually three plunger proportion adjustment pump of the present invention, the application are used to describe conveniently
Accompanying drawing for single plunger pump structural representation, and with single plunger pump describing.
The specific works mode of the high accuracy proportion adjustment pump of the present invention is as follows：
Entrance pipe 6 is connected with the mother solution header of outside, starts motor 14, and motor 14 passes through crank 15 and connecting rod 16 drives
Piston 2 moves back and forth, and when piston 2 is to chamber outdoor sport, the pressure of middle part chamber 12 is less than inlet chamber 13 and outlet
Chamber, mother solution then can flow into middle part chamber 12 from inlet chamber 13 by inlet one-way valve 3 due to pressure, when piston 2 is to chamber
During interior motion, chamber 12 pressure in middle part is more than outside pressure, and mother solution then can flow to inlet chamber from middle part chamber 12 due to pressure
13 and outlet chamber, but the opening direction of inlet one-way valve 3 flow with now mother solution it is in opposite direction, so mother liquor stream can be prevented
Oral chamber 13 is backed into, and only Outlet check valves 4 can allow mother solution to pass through and flow to outlet chamber, flowed out from export pipeline 7 immediately.
As piston 2 is moved back and forth in the presence of motor 14 and connecting rod 16, so mother solution can be in inlet one-way valve 3 and Outlet check valves
Circulate under 4 restriction from entrance pipe 6 and flow to export pipeline 7..
As middle part chamber 12 has connected circulation line 8 with inlet chamber 13, it is mounted with to adjust with taper on circulation line 8
The flow control valve 9 of section valve rod 10, the opening that taper regulating valve stem 10 adjusts circulation line 8 by screwing out or screwing in, so as to
Determine due to the refluence flow of the mother solution in the presence of pressure.Regulating valve stem 10 is screwed out, the enlarged open of circulation line 8, then female
Liquid refluence amount can increase, so as to the mother liquid flow rate of export pipeline 7 relative can be reduced；Regulating valve stem 10 is screwed in the same manner, circulation line 8
Opening diminish, mother solution refluence amount is reduced, and is increased so as to the mother liquid flow rate of export pipeline 7 is relative.Control mother liquid flow rate is reached
Accurate adjustable purpose.When regulating valve stem 10 is completely screwed into, the mother liquid flow rate of export pipeline 7 is maximum, taper regulating valve stem 10
When screwing out completely, the mother liquid flow rate of export pipeline 7 is minimum.
If flow control valve 9 is provided with YE 17 on flow control valve 9, is held using electronic to automatically adjust
The positive and negative precise control for being conveyed to flow of row device 17.Specifically, it is that effusion meter 5, control system, flow control valve 9 are constituted
Closed control circuit, effusion meter 5 feed back to flow control valve 9, flow control valve 9 by control system after detecting flow parameter
Again taper regulating valve stem 10 is controlled after parameter comparison according to setting, after the changes in flow rate of mother liquor outlet check valve 4 again
It is secondary to be detected by effusion meter 5, so as to feed back to flow control valve 9 again, such a closed loop control is reached, the shape for regulating and controlling at any time
State.
The high accuracy proportion adjustment pump of the present invention, can set on flow control valve 9 when not needing mother solution discharge capacity accurate
There is regulation handle, mother solution discharge capacity is adjusted by the way of adjusting manually, it is also possible in the presence of control system, make
Actuator, control system, effusion meter form closed control circuit, carry out high accuracy regulation to flow, additionally due to regulating valve stem
It is bullet, its shearing to mother solution is greatly reduced, makes the mother solution Quality advance of output.
