It is a kind of can be by the chemical proportioner of the adding liquid in proportion of the working fluid in pipeline.Lid, main cavity lower casing, diaphragm of rubber, pumping cylinder are constituted on main cavity, wherein main cavity is separated into two parts up and down by diaphragm of rubber, there is no any Mechanical course structure in its main cavity, dosing failure will not be caused because of mechanical wear, all control devices are all outside main cavity, diaphragm of rubber in cavity is controlled by magnetic valve with diaphragm position inductive switch, very simple, solve conventional chemical proportioner Chang Yinwei abrasion and in the inoperable weakness of low discharge.The medicine extracted simultaneously is delivered directly in the outlet pipe of chemical proportioner not by main cavity and magnetic valve from loading non-return valve, solves conventional magnetic valve easily by the problem of drug contamination failure, is inhaled medicine proportional precision and is greatly improved.
Description
Technical field：
The present invention relates to fluid machinery, more particularly to liquid diluting device, the working fluid in pipeline is particularly added to the chemical proportioner of another liquid in proportion.
Background technology：
In the prior art, proportional diluter doser is made up of the main piston of top half and the drawing liquid piston of the latter half, main piston is made up of fluid motor, drawing liquid piston extracts liquid, main piston is built with two groups of valves and the mechanical component of control valve, its principle is when main pipeline liquid flows through main piston main piston to be promoted to move upwards, when master piston motion is to top, and the main piston controlled by mechanical structure can be moved downward again.When running to foot, main piston can be moved upwards again, so be moved repeatedly, drive bottom drawing liquid piston to extract liquid into main pipe system, the movement velocity of piston and extract liquid number depend entirely on the uninterrupted of main pipeline.Flow is bigger, and piston movement is faster, and the liquid that bottom is extracted is more.Conversely, the liquid that bottom is extracted is fewer.Because whole system is controlled in piston what two groups of valves were carried out by the mechanical structure mounted in internal piston completely, therefore when water consumption decline flow velocity is relatively low, master piston motion is very slow, and when can cause one group of valve opening, another group of valve can not in time close and cause piston stop motion.Because mechanical sensitivity is relatively low, often generation piston, which is not closed completely, causes liquid leakage and is stopped, and lower piston and cylinder body are all to adopt made of plastic, easily worn and torn between piston and cylinder body, when run to 500 it is small when or so, gap can be produced because of abrasion between cylinder body and piston, now a part of liquid can flow directly into system by the gap between cylinder body and piston, cause doser not inhale medicine in low discharge.
The content of the invention：
It is an object of the invention to provide a kind of liquid fraction doser, described this liquid ratio dilution device to solve proportional diluter in the prior art can not be worked under low discharge state, low precision, the easy to wear and short technical problem of service life.

The present invention operation principle be：Water source and power supply are connected, control circuit opens the second entering water electromagnetic valve, the first water solenoid valve, and closes the first entering water electromagnetic valve and the second water solenoid valve.Water enters inlet channel, the second entering water electromagnetic valve and the second water inlet and flows into main cavity bottom, and the pressure of water promotes diaphragm of rubber to move upwards, and the water on diaphragm of rubber top enters outlet conduit by the first delivery port, the first water solenoid valve.
When main piston, which runs to cylinder body top, reaches the first diaphragm position inductive switch position, first diaphragm position inductive switch is acted, second entering water electromagnetic valve and the first water solenoid valve are closed by control circuit, while opening the first entering water electromagnetic valve and the second water solenoid valve.
After second entering water electromagnetic valve and the closing of the first water solenoid valve, the first entering water electromagnetic valve and the second water solenoid valve are opened, water flows into cylinder body top by inlet channel, the first entering water electromagnetic valve and the second water inlet, the pressure of water promotes barrier film to move downward, and the water of the lower end of main cavity enters outlet conduit through the second delivery port, the second water solenoid valve.
When diaphragm of rubber, which runs to cavity bottom, reaches the position of the second diaphragm position inductive switch, second diaphragm position inductive switch is acted, the first entering water electromagnetic valve and the second water solenoid valve are closed, while opening the second entering water electromagnetic valve and the first water solenoid valve, above-mentioned stroke is repeated.
In above-mentioned stroke, drawing liquid piston pumps with diaphragm movement, suction check valve is opened during drawing liquid piston upwards, non-return valve is exported to close, decoction is pumped into pumping cylinder lower end cylinder from bottom, when drawing liquid piston is moved downward, suction check valve is closed, and output non-return valve is opened, and the decoction originally sucked is transported in total outlet pipe road from pumping cylinder lower end through woven hose and output non-return valve.
Controlling the course of work of circuit is：Connect after electricity, relay is closed, power supply is powered by normally closed o'clock of relay to the second entering water electromagnetic valve and the first water solenoid valve, two magnetic valves obtain electric-opening, diaphragm of rubber is begun to move up, when diaphragm of rubber, which runs to top, reaches the first diaphragm position inductive switch position, first diaphragm position inductive switch is acted, relay adhesive, and pass through relay self-locking, second entering water electromagnetic valve and the first water solenoid valve are closed, the first entering water electromagnetic valve and the second water solenoid valve are opened simultaneously, barrier film starts to move downward, when barrier film reaches the second diaphragm position inductive switch end position, second diaphragm position inductive switch is acted, relay electric-loss is closed, power supply is powered to the second entering water electromagnetic valve and the first water solenoid valve again by the normally closed point of relay, two magnetic valves obtain electric-opening, barrier film is begun to move up again, restart next stroke.
The present invention is contrasted with prior art, and its effect is actively obvious.The liquid fraction doser of the present invention is sensed by outer membrane location sensitive switch and barrier film cleat surface metal film, detect the travel position of barrier film, and pass through solenoid valve control diaphragm movement, eliminate the abrasion produced in the past using piston with cylinder body, no matter in the case of big flow or low discharge can normal work and invariable precision, overcome mechanical wear generation error, long lifespan, precision is high, and range of flow is big.Because the lower end that the decoction of extraction is directly transported to total outlet pipe 18 without main cavity and magnetic valve by woven hose and transfusion non-return valve 23 is connected, greatly extend magnetic valve life-span and equipment operational reliability.
