Specific implementation mode
A kind of embodiment of anti-blocking waste water ratio electromagnetic valve of the utility model is as shown in Figures 1 to 6：Include valve body 1 and electricity
Magnetic driving mechanism 2, valve body 1 include inner cavity, and water cut off device 11 and the diaphragm with 11 fitted seal of water cut off device are provided in inner cavity
Component 3, for diaphragm assembly 3 by 2 drive motion of electromagnetic drive mechanism, electromagnetic drive mechanism 2 includes movable core 21, electromagnetic coil 22
And driving spring 23,1 upper end of valve body are provided with conduit 24, movable core 21 is slidably set in conduit 24, electromagnetic coil
22 are sheathed on outside conduit 24, and the upper end of conduit 24 is provided with static iron core 25, and movable core 21 is slidably set in conduit 24,
Driving spring 23 is set between movable core 21 and static iron core 25, and diaphragm assembly 3 includes the diaphragm 31 and diaphragm being mutually socketed
Inner cavity is divided into intake chamber 12, water-supplying chamber 13 and back pressure chamber 14, unicom is provided on diaphragm assembly 3 by plate 32, diaphragm assembly 3
The relief hole 34 of water-supplying chamber 13 and back pressure chamber 14,21 lower end of movable core are provided with the plug 26 with 34 fitted seal of relief hole,
The water inlet pipe 15 being connected to respectively with intake chamber 12 and water-supplying chamber 13 and outlet pipe 16, the outlet pipe 16 are provided on valve body 1
On be provided with throttling pore 17 on tube wall relative to intake chamber 12, be provided on the diaphragm assembly 3 and moved with diaphragm assembly 3
Disclose needle 41, the one end and diaphragm assembly 3 for disclosing needle 41 are relatively fixed, disclose needle 41 other end activity be threaded through throttling pore 17
In, it throttles and 17 inner wall of pore and discloses between needle 41 that there are the gaps that water supply stream passes through.In the present invention, the needle of disclosing refers to
It is relatively fixed with diaphragm assembly 3, and the needle-shaped or columnar object realized and be axially moved can be driven by diaphragm assembly 3.
In the present embodiment, diaphragm assembly 3 can be pressed in when solenoid valve is closed by being provided in the back pressure chamber 14
Holddown spring 42 at water cut off device 11, which is butted between 14 inner wall of back pressure chamber and diaphragm assembly 3, described to disclose needle 41
It is bent to form by one end of holddown spring 42 towards diaphragm assembly 3, offers on diaphragm assembly 3 and worn to intake chamber 12 for disclosing needle 41
In jack.
The jack can be made of the through-hole being independently opened on diaphragm assembly 3, it is therefore an objective to allow disclose needle 41 can be by
The upper end of diaphragm assembly 3 is worn to 3 lower end of diaphragm assembly, in order to which activity is inserted in throttling pore, but in the present embodiment,

The operation principle of the utility model：When waste water ratio electromagnetic valve no power, movable core 21 is in driving spring 23
Relief hole 34 is withstood on diaphragm assembly 3 and blocked simultaneously under effect, and holddown spring 42 can also give diaphragm assembly 3 and block direction
Pressure.At this point, the water of intake chamber 12 is entered by hole 33 of boosting in back pressure chamber 14, make all to fill in intake chamber 12 and back pressure chamber 14
Full water makes diaphragm assembly 3 be tightly pressed against on water cut off device 11 since movable core 21 is applied with certain pressure to diaphragm assembly 3, this
When intake chamber 12 water only by throttle pore 17 be flowed on a small quantity in water-supplying chamber 13；When waste water ratio electromagnetic valve is powered, activity
Iron core 21 overcomes the pressure of driving spring 23 to move under electromagnetic drive, and relief hole 34 is made to open, and the water of back pressure chamber 14 can pass through
Relief hole 34 enters in water-supplying chamber 13, since the water of intake chamber 12 enters the access only boosting hole 33 of back pressure chamber 14, stream
Speed is slower, therefore the hydraulic pressure in back pressure chamber 14 is reduced rapidly, when the hydraulic pressure in intake chamber 12 is more than the hydraulic pressure in back pressure chamber 14,
Diaphragm assembly 3 overcomes the pressure of holddown spring 42 open-top from water cut off device 11, makes the water in intake chamber 12 can be from water cut off device 11
Place flows directly into water-supplying chamber 13.
Above example, only one kind of the utility model preferably specific example, those skilled in the art are new in this practicality
The usual variations and alternatives carried out in type technical proposal scope are included in the scope of protection of the utility model.
