Background technology
At present, popularization and application along with electrical equipment such as gas heater and electric heaters, need a large amount of aqueous vapor interlocks or the switching device of water-electricity linkage, especially quick electric water heater, some transducers require energy water, electricity stops simultaneously, in order to accomplish this point, usually adopt the mode of rear-mounted tap and electromagnetically operated valve, yet the shortcoming of trailing water tap is that single user's water can only be provided, when needs multi-user water, must adopt forward type tap form, and the problem of forward type faucet mounted is: when the Close All tap, because tap is to a biography distance being arranged, electromagnetically operated valve induction appearance hysteresis between transducer and the electromagnetically operated valve, cause transducer work to lag behind, cause unnecessary energy waste.
In order to solve the problem that transducer work lags behind, can on the water pipe of transducer delivery port, inductive switch be installed,, can be about to close and before not closing at tap by inductive switch, the signalisation controller and make closed electromagnetic valve, reach synchronously even the purpose of leading control.
Inductive switch commonly used is a magnetic induction switch, it has characteristic of simple structure, it has a body and the external magnetic red pipe of body, body is built-in with an alien that can reset, the alien is built-in with a permanent magnet, when the alien when the effect of current is moved near the magnetic red pipe, the permanent magnet in the alien is had an effect to the outer magnetic red pipe of body, and magnetic red pipe on off state is changed.
Alien's resetting means of existing magnetic induction switch has magnetic patch formula (utilizing principle of same-sex repulsion) and float-type, can not be used for quick electric water heater because its sensitivity is high, particularly adopt the water heater of carbon graphite piece (is 03226396.1 as the patent No.) as transducer.
The utility model content
The purpose of this utility model provides a kind of fluid flow magnetic induction switch simple in structure, highly sensitive, adjustable.
The utility model is realized by following technical solution:
A kind of fluid flow magnetic induction switch, comprise body and magnetic red pipe, the two ends of body are provided with connector, body is built-in with an alien and alien's resetting means, the alien is built-in with a permanent magnet, the alien moves with flowing of liquid in the body, the parallel outside that adheres on body of magnetic red pipe, in the time of near the alien in the body moves to the magnetic red pipe, place the permanent magnet magnetic force interaction energy in the alien to cause being switched on or switched off of magnetic red pipe, it is characterized in that: described alien's resetting means comprises back-moving spring and hollow adjusting back-up ring, the alien places water inlet oral-lateral in the body, hollow adjusting back-up ring is installed on the water outlet oral-lateral by screw thread, and back-moving spring places between alien and the hollow adjusting back-up ring.
As optimization, the sectional area along liquid flow direction in the body increases gradually.
As optimization, described hollow adjusting back-up ring can be adjusted along the axis direction of liquid outlet side in the body.
Be compared with the prior art, of the present utility model have following characteristics:
1, control is highly sensitive, and the spring in alien's resetting means is even, and the alien's is mobile smooth and easy.
2, simple and reasonable, good reliability, easy to manufacture, cost is low, and is easy to utilize.
3, adaptability is strong, adopts alien's resetting means of adjustable seamless power, can be applicable to different hydraulic pressure environment.

Embodiment
With a specific embodiment the utility model is further described below:
Be illustrated in figure 1 as a kind of cutaway view of feasible fluid flow magnetic induction switch, comprise body 1 and magnetic red pipe 3 and place alien 2 in the body 1 and the trip resetting means of forming by back-moving spring 23 and hollow adjusting back-up ring 21, the liquid-inlet 5 of body 1 is provided with the external screw thread connector, and liquid outlet 6 is provided with female screw connection;
The alien 2 of cylindrical shape places liquid-inlet 5 sides in the body 1, permanent magnet 22 is embedded in the alien 2, hollow adjusting back-up ring 21 is provided with the external screw thread that matches with the internal thread of liquid outlet 6, hollow adjusting back-up ring 21 is installed on liquid outlet 6 places by screw thread, and back-moving spring 23 places between alien 2 and the hollow adjusting back-up ring 21.
The magnetic red pipe 3 parallel outsides that adhere on body 1 in the time of near the alien in the body 12 moves to magnetic red pipe 3, place the permanent magnet 22 in the alien 2 can cause that the switch 4 of magnetic red pipe 3 is switched on or switched off, and magnetic red pipe 3 and controller 7 are electrically connected;
Regulate the position of hollow adjusting back-up ring 21 in body 1, make 23 couples of aliens' 2 of back-moving spring pressure difference, to adapt to different hydraulic pressure environment.In the lower area of hydraulic pressure, hollow adjusting back-up ring 21 can be adjusted toward the outside, alleviate 23 couples of aliens' 2 of spring pressure, make lower hydraulic pressure can both promote alien 2 and move.
The shape of being arranged to increase gradually along the sectional area of liquid flow direction (shown in arrow among the figure) in the body 1, when hydraulic pressure is big, cross the corresponding increasing of water sectional area, when hydraulic pressure hangs down like this, cross the corresponding minimizing of water sectional area, the distance that alien 2 is moved is controlled in the suitable scope.
