Size relation changes and the movement repeatedly of work level between the power of spring.Throttling valve core can realize first during the motion
The dredging of throttle orifice and the second throttle orifice, to avoid the phenomenon that generating inorganic salts fouling.
The principle of decompression, the throttling of throttle valve in the present invention are as follows: when hydraulic pressure increases before throttle valve, throttling valve core is by water
Bear down on one out, spool is integrally moved to water (flow) direction, and the centrum of throttling valve core can protrude into the second throttle orifice and cause a degree of block up

Using water inlet equipment in as decompression member come using.
In the prior art, the structure of the waste water solenoid valve used on water purifier is as shown in fig. 7, its Throttle Principle are as follows: electromagnetism
There is aperture in valve base side wall, solenoid valve is in off-position in the water purifier course of work, and water is only capable of flowing out valve from side wall aperture
It is interior, because side wall small aperture is smaller, biggish hydraulic pressure can be formed before aperture, generate restriction effect.This solenoid valve
Two states are only opened and closed, the waste water ratio of water purifier is not adjustable, and the environmental wastewater solenoid valve poor in water quality, throttling pore
It is easy to block because of inorganic salts crystallization, to cause water purifier operation irregularity.
The present invention substitutes original waste water solenoid valve using the solenoid valve for being equipped with above-mentioned throttle valve.In solenoid valve not water receiving
Elastic acting force of the throttling valve core by the first relief spring under the state of source makes the cone cylinder part of throttling valve core withstand first throttle
Hole；The whole elastic acting force by the second relief spring of throttle valve, moves downward until the limit of positioning knob.In electromagnetism
In the state of valve water receiving source, the working condition of this solenoid valve specifically includes following several situations:
The first: power-down state: the elastic acting force that spool receives valve core spring moves downward, the silica gel plug on spool
The upper end outlet of valve base central tube is blocked, water cannot directly enter central tube to from the water outlet of valve base at this time
Outflow, can only enter lateral channel by runner hole.In the presence of hydraulic pressure, throttle valve subtracts to water (flow) direction motion compresses second
Pressing spring.There are sealing device, i.e. the first sealing ring and the second sealing ring between lateral channel and throttle valve, so that water can only pass through
Throttle valve enters valve base central tube.The water for flowing through throttle valve needs the elastic acting force for overcoming the first relief spring that could flow
Via first segment discharge orifice and the second throttle orifice by lateral channel, and solenoid valve valve is flowed out through valve base central tube and water outlet
Body.It is all that there is throttling action because the aperture of first segment discharge orifice and the second throttle orifice is smaller.
When hydraulic pressure is smaller, elastic acting force of the throttling valve core by the first relief spring, throttling valve core diameter is lesser
Tapering end is still protruded into first segment discharge orifice.It can be removed at this time with the area that the area of the first segment discharge orifice of water flowing is first segment discharge orifice
The area at the tapering end of throttling valve core.
When hydraulic pressure increases, the first relief spring and the second relief spring are slowly compressed into most short status.This process
In, the centrum end of throttling valve core slowly can generate blocking effect to the second throttle orifice, therefore the flow of throttle valve rear end will not be with
The increase of hydraulic pressure and increase, but can be defined within the scope of one according to the elastic force of spring.
Second: power-up state: electromagnetic coil is powered, and spool is moved upwards compression valve core spring by electromagnetic force, on spool
Silica gel plug follow spool to move upwards, open valve base central tube upper end outlet, water is directly from valve base central tube
It flows to outside valve body.
Using the above-mentioned characteristic of solenoid valve, waste water ratio can be adjusted by controlling the power of water purifier water pump.Work as needs
Process control water pump increases output power to increase the hydraulic pressure after water pump when improving waste water ratio.At this point, because the water outlet at waste water end
It is limited, then the water-flowing amount of RO equipment will increase, and increase water purification water yield, achieve the purpose that adjust waste water ratio.Meanwhile in hydraulic pressure
First segment discharge orifice and the second throttle orifice can be throttled spool and be dredged in change procedure, and therefore, two throttle orifices are not easy to occur
The phenomenon that inorganic salts fouling, blocking.
In practice, the present invention can not only be used as throttle switch, but also can be used in the biggish pipe network system of pressure
It is middle to be connect using the solenoid valve with water equipment, it can effectively avoid impact of the water hammer to water equipment.For section of the present invention
Valve is flowed, solenoid valve can both use, and can also be used in series with general solenoid valve like that as described herein.
