Technical field
The utility model relates to a kind of axial-flow type water flow sensor with flow stabilizing function.
Background technology
There is the water flow sensor of flow stabilizing function mainly by valve body, turbine assembly, current stabilization plug assembly, whole of piece and wire harness assembly.It is contained in the water inlet end of water heater for measuring flow of inlet water.In the time that water flows through sensor valve body water stream channel, the magnet rotor of the inside is subject to the impact of water and rotates, and rotating speed is along with the variation of flow rate of water flow forms linear change, therefore Hall element produces electromotive force, output pulse signal feeds back to controller, judged the size of discharge by controller, the discharge size information control combustion gas tolerance size that controller feeds back by axial-flow type water flow sensor, realizes adjusting or other regulating and controlling function of temperature.
Utility model content
The utility model, for the demand of present situation, provides a kind of axial-flow type water flow sensor with flow stabilizing function.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The axial-flow type water flow sensor with flow stabilizing function, comprises valve body, and valve inner is provided with turbine assembly and current stabilization plug assembly, is also connected with whole of piece on valve body, and the rotating shaft of described turbine assembly and rotor are one-time formed entirety, and described rotor is magnet rotor.The impeller using in conventional flow quantity sensor and magnet ring are two individual part, and by collar, magnet ring are fixed on plastic impeller.This axial-flow type water sensor, changes traditional design concept, adopts magnet rotor to substitute impeller and the magnet ring in traditional water flow sensor completely, and its stainless steel rotating shaft and magnet rotor, by moulding magnetic technology one-shot forming, are an entirety.This design improves the stability that flow sensor signal gathers greatly, has simplified production technology simultaneously, has reduced production link operation, has reduced production cost.
As preferably, described rotating shaft is made up of stainless steel, and magnet rotor is made up of plastics magnetic material.
As preferably, described valve body is arranged on the water inlet end of water heater, with water stream channel be same passage.There is measuring accuracy height and stable feature, for the flow of promptly and accurately measuring and control water has been created advantage.
As preferably, described valve body injection moulding one-shot forming.Change the design of traditional water flow sensor, adopt integrated design, and lengthen valve body length dimension, remove conventional flow quantity sensor adapter coupling and cover plate part, utilize injection moulding one-shot forming, make whole product become independently entirety of a sealing.
As preferably, described whole is made up of piece and printed board assembly, and printed board assembly comprises printed board and Hall element and wire harness assembly, by epoxide resin encapsulation material, piece and printed board assembly embedding is integrally formed to whole of piece.
As preferably, also comprise current stabilization plug assembly, current stabilization plug assembly is arranged on the water side of valve body.Discharge constant-current stabilizer is integrated on this product.According to the existing bulk of valve body, have flow stabilizing function the water side design and installation of axial-flow type water flow sensor " current stabilization plug " device, thereby when making product have flow sensor function, also possessed flow stabilizing function, product allomeric function is greatly improved.
As preferably, the O type circle that current stabilization plug assembly comprises current stabilization plug, current stabilization plug shell and adjust flux size.In the time that input hydraulic pressure becomes large, current stabilization plug is subject to Water Pressure displacement forward, and pressure is passed to current stabilization O type circle, and now current stabilization O type circle produces elastic deformation under pressure, and regulating flow-stabilizing plug water delivering orifice size, remains within the specific limits discharge automatically.Otherwise in the time that input hydraulic pressure diminishes, current stabilization plug imposes on current stabilization O type circle pressure and diminishes, now current stabilization O type circle elastic reset, it is large that water delivering orifice size becomes, and it is large that flow also becomes thereupon.By the adjusting of current stabilization plug, guarantee that, under different input hydraulic pressure, discharge remains in certain corresponding scope.Greatly improve thus the degree of regulation of controller.
There is the axial-flow type water flow sensor of flow stabilizing function again by independent to flow collection and temperature acquisition part, become two individual components, when installation, only need simple fixing, the multiple spot that has greatly reduced former valve body is connected and fixed and fit sealing part, has reduced part and production cost.
Having the axial-flow type water flow sensor of flow stabilizing function according to the technical solution of the utility model, for constant temp gas water heater, is the product of a kind of advanced person's the accurate Detection & Controling of Novel flow rate.It has adopted Hall effect principle, in the time that water flows through sensor valve body water stream channel, the magnet rotor of the inside is subject to the impact of water and rotates, and rotating speed is along with the variation of flow rate of water flow forms linear change, therefore Hall element produces electromotive force, and output pulse signal feeds back to controller, is judged the size of discharge by controller, the discharge size information control combustion gas tolerance size that controller feeds back by axial-flow type water flow sensor, realizes adjusting or other regulating and controlling function of temperature.
Due to the further optimization of profile, reduce taking of space, make the inner structure design of complete machine more flexible, profile is smaller and more exquisite.
