Abstract
This invention relates to a flow switch, and the flow switch comprises the main-body equipped with fluid channel, the baffle connecting with the upper activities of fluid channel, and the magnetic sensing switch installed in the magnet of the baffle and matching with the magnet. Through the using of the said structure, when the fluid within the fluid channel flows, the baffle deflects and the magnet triggers the magnetic sensing switch, in order to control the on-and-off of the external circuit.
Description
[technical field]
The present invention relates to a kind of flow switch, particularly a kind of magnetic inductive flow switch.
[background technology]
In the passage of many liquid or gas transmission, need the use traffic switch usually.For example in water heater, just need the use traffic switch to come to control the ON/OFF and the sparking of coal gas according to the on/off of current.As shown in Figure 1, Fig. 1 is the cutaway view of prior art flow switch.In the flow switch 1 of prior art, upper inside wall in pipe joint 11 is rotatably connected to baffle plate 13,15 rotate and promote pole 17 around the shaft under the pressure effect of baffle plate 13 working fluid in pipe joint 11, by the electric contact 19 in the pole 17 connection annular seal spaces 18, and then the connection of realization circuit.The shortcoming of this flow switch is that sealing effectiveness is relatively poor, and liquid enters in the annular seal space 18 along pole 17 easily, causes short circuit or leakage.
[summary of the invention]
For the flow switch that solves prior art is realized switch control mechanically, thereby liquid flows out the technical problem that causes short circuit or leakage along mechanical part easily, the invention provides a kind of flow switch that utilizes magnetic induction part to realize contactor.
The present invention solves the flow switch of prior art and realizes switch control mechanically, thereby liquid along the technical scheme that mechanical part flows out the technical problem cause short circuit or leakage is easily: a kind of flow switch is provided, the baffle plate that this flow switch comprises the main body that is provided with the fluid passage, be rotationally connected with the top of fluid passage, be arranged on the baffle plate magnet and with the supporting magnetic induction switch of magnet.
According to one preferred embodiment of the present invention, baffle plate is connected by hinge axis with the top of fluid passage.
According to one preferred embodiment of the present invention, when flow in the fluid passage was zero, baffle plate was perpendicular to the longitudinal axis of fluid passage.
According to one preferred embodiment of the present invention, under the effect of the fluid that baffle plate flows in the fluid passage around hinge axis to predetermined angular, the magnetic field that makes the magnetic induction switch place is greater than predetermined threshold.
According to one preferred embodiment of the present invention, main body, baffle plate and hinge axis are non-magnetic permeability material.
According to one preferred embodiment of the present invention, magnetic induction switch is arranged in the annular seal space on the outer wall of fluid passage.
According to one preferred embodiment of the present invention, magnetic induction switch is tongue tube or Hall switch.
According to one preferred embodiment of the present invention, main body is formed by two conduit component butt joints.
According to one preferred embodiment of the present invention, on two conduit components recess and the flange that cooperatively interacts is set.
By adopting said structure, when the fluid in the fluid passage flowed, baffle plate deflection also triggered magnetic induction switch by magnet, controls the break-make of external circuit thus.Because magnetic induction switch and fluid passage isolate fully, and then short circuit and leakage problem in the prior art flow switch of avoiding, and simple in structure, low cost of manufacture, production in enormous quantities easily.

[embodiment]
The present invention is described in detail below in conjunction with drawings and Examples.
As shown in Figure 2, Fig. 2 is the profile of flow switch one embodiment of the present invention.In the present embodiment, flow switch 2 comprises the baffle plate 23 that the main body 21 that is provided with fluid passage 22, the top by hinge axis 25 and fluid passage 22 are rotationally connected.Baffle plate 23 is provided with magnet 27, is provided with annular seal space 28 at the outer wall of main body 21, is provided with tongue tube 29 in the annular seal space 28.Have in fluid passage 22 under the situation that fluid flows, baffle plate 23 can be around hinge axis 25 deflections under the effect of fluid, and when flow rate of fluid during greater than certain threshold value, baffle plate 23 deflects into predetermined angular, the action of a magnetic field tongue tube 29 of fixing magnet 27 on the baffle plate 23.Tongue tube 29 adopts the open type tongue tube, and two ferromagnetism reeds are housed in the glass tube of tongue tube 29, and an end of this reed with certain interval toward each other.When magnet 27 during near tongue tube 29, two reeds magnetize respectively and the opposite polarity N utmost point and the S utmost point, thereby and thus mutually adhesive connect external circuit.Be filled with inert gas in the glass tube and be coated with inert metal, to prevent the reed activation at the place, contact.When the flow of fluid passage 22 inner fluids was zero, baffle plate 23 was under the effect of himself gravity, perpendicular to the y direction of fluid passage 22.At this moment, the magnetic field of magnet 27 no longer acts on tongue tube 29, and the reed of tongue tube 29 is because self elastic return original state and open circuit.The position that 22 axis, fluid passage when employed in this application " top " is meant and uses are above, the inwall top of fluid passage 22 preferably is so that when flow was zero in fluid passage 22, baffle plate 23 utilized self gravitation to fall after rise naturally.In the present embodiment, main body 21 is preferably formed by two conduit component butt joints, and before will docking baffle plate 23 is connected on the abutting end of a conduit component, to simplify processing procedure.In addition, be respectively equipped with the recess and the flange that cooperatively interact on the abutting end of two conduit components, to increase the stability and the seal of fluid passage 22.
As shown in Figure 3, Fig. 3 is the profile of flow switch one embodiment of the present invention.Flow switch 3 shown in Figure 3 is with the difference of flow switch shown in Figure 2: in the annular seal space 38 on main body 31 outer walls Hall switch 39 is set.For example, Hall switch 39 can comprise pressurizer, Hall plate, differential amplifier, this schmitt trigger and output stage.Under the effect in the magnetic field of magnet 37, when magnetic field intensity surpasses conduction threshold, Hall switch 39 conductings.
Main body in the embodiment of above-mentioned fluid switch, baffle plate, hinge axis and annular seal space preferably adopt non-magnetic permeability material, avoid above-mentioned parts by magnet magnetization, and then avoid the influence to magnetic induction switch.In addition, above-mentioned magnetic induction switch can also be arranged on other appropriate location that can be affacted by magnetic field of magnets.
In the above-described embodiments, only the present invention has been carried out exemplary description, but those skilled in the art can design various execution modes according to different actual needs under the situation of the scope and spirit that do not break away from the present invention and protected.
