In: described waste water tunnel is relative with the end of flow inlet UNICOM and valve rod and is coaxially disposed, institute
The valve rod stated is coaxially arranged with constriction, described Electromagnetic Drive machine towards the end of waste water tunnel
Structure stretches into waste water tunnel by valve rod driven diaphragm constriction in time crossing mouth from waste water tunnel
And move axially along waste water tunnel；Described electromagnetic drive mechanism by valve rod driven diaphragm away from
When crossing mouth, constriction moves in waste water tunnel to waste water tunnel, described constriction and waste water
The regulation gap that fluid passes through is existed between passage inner peripheral surface.
By use technique scheme, change waste water tunnel towards so that it is relative with diaphragm,
The driving force of Appropriate application electromagnetic drive mechanism, makes constriction move simultaneously the when of making diaphragm move
Dynamic, constriction diaphragm fitted mouth, valve body be in closure state time, regulation gap is used for supplying
A part of fluid is discharged, and when diaphragm left mouth, valve body is gradually opened, constriction leaves useless
The moment of aquaporin produces difference in flow, produces waste water tunnel inner peripheral surface and washes away, thus eliminates useless
The dirt that aquaporin inner peripheral surface is piled up, makes electromagnetic valve have the function of scale removal, additionally, constriction
Also the waste water tunnel making single aperture has the function of regulation flow, changes the current limliting of different-diameter
Part, makes function more diversification, and controllability is more preferable.
This utility model is further arranged to: the position that described valve rod is relative with constriction is arranged
Having installation cavity, described constriction is provided with towards the end of installation cavity and is mounted at peace
The constriction mounting blocks behaveing affectedly.
By using technique scheme, constriction mounting blocks is easy to the installation of constriction and tears open
Unload, various sizes of constriction can be changed according to different demands, thus produce different between
Gap and different current limliting durations, produce different effects, and dismountable mounting means include card
Join, be embedded in and plug together.
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.

Detailed description of the invention
As Figure 1-Figure 4, the utility model discloses a kind of electricity with scale removal mechanism
Magnet valve, including valve body 1, valve rod 2, diaphragm 3 and electromagnetic drive mechanism 5, Electromagnetic Drive machine
Structure 5 drives valve rod 2 axially and to stretch towards valve body 1 along valve rod 2, and diaphragm 3 is fixedly installed on
The other end of the relative electromagnetic drive mechanism 5 of valve rod 2 is also positioned at valve body 1, arranges in valve body 1
Having runner 11, this runner 11 is provided with flow inlet 111 and goes out head piece 112, this runner 11
In flow inlet 111 and go out to arrange relative with diaphragm 3 mistake mouth 113, electromagnetism between head piece 112
Valve is provided with the waste water tunnel 114 in parallel with crossing mouth 113, waste water tunnel 114 in runner 11
Be oppositely arranged with the end of flow inlet 111 UNICOM with valve rod 2 and be coaxially disposed, valve rod 2 towards
The end of waste water tunnel 114 is coaxially arranged with constriction 4, and electromagnetic drive mechanism 5 passes through valve rod
2 driven diaphragm 3 constriction 4 in time crossing mouth 113 stretches into waste water from waste water tunnel 114 and leads to
Road 114 also moves axially along waste water tunnel 114；Electromagnetic drive mechanism 5 is driven by valve rod 2
Diaphragm 3 moves to waste water tunnel 114 in waste water tunnel 114 away from constriction 4 when crossing mouth 113
Outward, the regulation gap that fluid passes through is existed between constriction 4 and waste water tunnel 114 inner peripheral surface
1141, the waste water tunnel 114 mentioned in literary composition coordinate with constriction 4 for waste water tunnel 114
A part, remainder by turning to and can go out head piece 112 UNICOM, change waste water tunnel 114
Towards so that it is relative with diaphragm 3, the driving force of Appropriate application electromagnetic drive mechanism 5, make
Making constriction 4 move the when that diaphragm 3 moving, constriction 4 was fitted mouth at diaphragm 3 simultaneously
113, when valve body 1 is in closure state, regulation gap is used for discharging for a part of fluid, and
When diaphragm 3 left mouth 113, valve body 1 is gradually opened, constriction 4 leaves waste water tunnel 114
Moment produce difference in flow, waste water tunnel 114 inner peripheral surface is produced and washes away, thus eliminate waste water
The dirt that passage 114 inner peripheral surface is piled up, makes electromagnetic valve have the function of scale removal, additionally, current limliting
Part 4 also makes the waste water tunnel 114 in single aperture have the function of regulation flow, changes different straight
The constriction 4 in footpath, makes function more diversification, and controllability is more preferable.
