Background technique
In daily life, what magnetic induction fluid switching valve used is more and more extensive, in existing technology, the magnetic of installation
Fluid switching valve is incuded by the control system of the water-flow signal feedback feed pump of induction, to control the start and stop of water pump；In order to full
Use demand in foot life, needs to install check-valves before or after magnetic induction fluid switching valve, and ability is combined in such installation
Simultaneously reach water-flow signal induction and non-return it is difunctional；But not only increased use cost is installed in such combination, simultaneously
Also it gives to install and use and brings many troubles.
Therefore occur this difunctional combined magnetic induction fluid switching valve in the market, but pass through when this switch valve
Hinged one piece of swivel plate, fluid are dug by swivel plate in valve body in valve body, and induced magnet and electromagnetism sense are arranged on swivel plate
It answers element corresponding to realize induction, there is no fluid entrance at valve body import channel, swivel plate falls realization check function, but
It has the following deficiencies: first is that fluid detection needs swivel plate to rotate the magnet and electromagnetic induction element pair that can just make above when incuding
Detection signal should be issued, the angle position installed on swivel plate to magnet in this way will be very accurate, and induction is easy to cause to feed back
Inaccuracy is sensitive, leads to the start and stop of control water pump not in time；Second is that the check function of swivel plate is using self gravity inertia, certainly
The case where so hanging closing, but will appear and close not in time, cause reverse flow of fluids；Third is that the installation of swivel plate needs one
Articulated shaft is realized to be rotated with valve body relative positioning, not only installation trouble, but also the seal request between articulated shaft and hinge hole
Height is easy to cause the junction of the intracorporal fluid of valve between the two to leak.
Summary of the invention
The utility model provides a kind of magnetically inductive cross-flow control valve to solve disadvantages described above, incudes the detection of fluid more
It is accurate it is sensitive, can timely realize check function, while mounting structure is simple and effectively guarantees its leakproofness.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of magnetically inductive cross-flow control valve, including
Valve body, twist-on has a valve deck on valve body, and valve body has intake channel and an exit passageway, in valve body and intake channel and exit passageway it
Between be provided with seal valve seat, be provided with through-hole at seal valve seat；Be equipped on the valve deck bar in valve, in valve bar by nut with
Valve deck is formed relatively fixed and is in valve body, is provided with mounting hole in the valve in bar, is provided with electromagnetic induction in mounting hole
Component, bar is made of fixed part and positioning sliding part two parts and forms ring-shaped step between the two in the valve；Bar in the valve
Positioning sliding part on be arranged with sliding plug, reset spring, the sliding plug is internally provided with to be matched with positioning sliding part
Positioning slide opening, it is external be provided with the annular convex platform that can be abutted with seal valve seat, the sliding plug is by positioning slide opening along determining
Position sliding part carries out movement, to realize opening or closing for through-hole, and described reset spring one end abuts with ring-shaped step, is another
End is abutted with annular convex platform；The positioning slide opening bottom is provided with magnet corresponding with electromagnetic induction component and is kept off with opening
Magnet is fixed in positioning slide opening by circle.
The positioning slide opening upper inside wall is provided with seal groove, is provided with O-ring seal in seal groove.
It is provided with the upper locating slot with reset spring upper end Corresponding matching on the ring-shaped step, is set on the annular convex platform
It is equipped with the lower locating slot with reset spring lower end Corresponding matching.
Encapsulated gasket is provided in the valve between bar and valve deck.
The utility model has the following beneficial effects:
Compared with existing technology, the utility model is fixed with bar in valve with nut on valve deck, your twist-on of valve deck and valve body, valve
Middle bar inner upper end is provided with electromagnetic induction component, lower end connection sliding plug, is provided in sliding plug and electromagnetic induction
The corresponding magnet of component, when having fluid to enter in valve body, sliding plug is jacked up upwards, and magnet also moves up and electromagnetic induction
Component generates electromagnetic induction signal, and water pump can keep operating, and when valve body import channel there is not fluid to enter, sliding plug can be multiple
Rapid reset is by through-hole under the elastic force of position spring, thus the function of preventing the fluid in exit passageway from water conservancy diversion occurs, plays non-return；
Electromagnetic induction signal is made while fluid on-off situation in valve body can sensitively be detected and in time to control opening for water pump
Stop；When passing through in valve body without fluid, sliding plug timely closes through-hole, and structure is easy for installation, improves use
Leakproofness.
Furthermore electromagnetic induction component can be disassembled individually, convenient for the maintenance and installation in later period.
Detailed description of the invention
Fig. 1 is the sectional view of the utility model.
Specific embodiment
The utility model is further elaborated in conjunction with attached drawing.
Referring to Fig. 1, the utility model provides a kind of magnetically inductive cross-flow control valve, including valve body 1, twist-on on valve body 1
