Abstract
The utility model discloses a rotary wing type liquid-flow annunciator which comprises a rotary wing wheel, a rotating disk or pointer, a sensor, a shell and a pressing cover with a transparent window. The rotary wing type liquid-flow annunciator is characterized in that the rotary wing wheel is mounted in a shell cavity, and two ends of the shell cavity are communicated with a pipeline. The rotating disk or pointer is provided with a signaling device and connected onto the rotary wing wheel, and the sensor is mounted on the rotating circumference of the rotating disk or pointer and does not contact with the rotating disk or pointer. The rotary wing type liquid-flow annunciator has the advantages that the annunciator is simple in structure and stable and reliable in operation, and the flow state of fluids in the pipeline can be reliably detected under low flow and low pressure.
Description
Technical field
The utility model relates to one and shows stream signalling means, belongs to automation instrument technical field, and especially a kind of rotary wind type is shown stream signalling means.
Background technology
Show that stream signalling means is to detect the flow state of pipeline inner fluid and convert this state to a kind of automation instrument that electric signal gathers for automated system.Existing showing flowed signalling means for responding to the mobile device of fluid, mostly adopt corrugated tube, in the time that pipeline inner fluid flows, before and after corrugated tube, mineralization pressure is poor, this pressure differential drives corrugated tube to move to touch microswitch, and closed the or disconnection of microswitch contact has represented the mobile state of pipeline inner fluid.Thisly show that the shortcoming that flows signalling means is: when fluid flows while being slowly low discharge, pressure differential is little, cause the movement of corrugated tube to be not enough to touch microswitch action, this can not accurately reflect the flow state of pipeline inner fluid, also the working pressure of this kind of signal current indicator requires large (more than being generally 0.2～0.3MPa), and the occasion that is not suitable for low discharge low-pressure is used.
Summary of the invention
The purpose of this utility model is the weak point overcoming in prior art, provides a kind of rotary wind type to show stream signalling means.This current indicator is simple in structure, and working stability is reliable, can detect reliably the flow state of pipeline fluid under compared with low discharge and lower pressure.For achieving the above object, the technical solution of the utility model is: a kind of rotary wind type is shown stream signalling means, comprises rotary wing wheel, rotating disc or pointer, inductor, shell, with the gland of transparency window, it is characterized in that: described rotary wing wheel is arranged in outer shell cavity outer shell cavity two ends and pipeline communication.Described rotating disc or pointer are equipped with sender device, and rotating disc or pointer are connected on rotary wing wheel.Described inductor is arranged on the circumference of rotating disc or pointer rotation, and inductor and rotating disc or pointer are contactless.
Described rotary wing wheel is the rotary wing wheel of existing rotor water gauge, and this rotary wing wheel, can initiating rotation under the pressure lower than 0.02MPa according to the detection performance data of water meter.
Described sender device is: magnet steel.
Described inductor is the magnetic induction device corresponding with the sender device that is contained in rotating disc or pointer, as tongue tube, Hall element etc., or is photoelectric device.
In the time that the fluid of utmost point low-pressure is flowed through outer shell cavity, rotary wing wheel rotation, rotary wing wheel driven rotary dish or pointer rotation, rotating disc or pointer often rotate a circle, sender device on it just triggers inductor one time, an electric pulse of inductor output, this electric pulse is pipeline inner fluid flow signal, for automated system collection.
Owing to adopting technique scheme, the beneficial effects of the utility model are: simple in structure, working stability is reliable, can detect reliably the flow state of pipeline fluid under compared with low discharge and lower pressure.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In Fig. 1,1 is rotary wing wheel, and 2 is rotating disc or pointer, and 3 is inductor, and 4 is shell, and 5 is the gland with transparency window.
Embodiment
With reference to accompanying drawing 1, the utility model comprises rotary wing wheel (1), rotating disc or pointer (2), inductor (3), shell (4), the gland (5) with transparency window.Described rotary wing wheel is arranged in outer shell cavity, outer shell cavity two ends and pipeline communication.Described rotating disc or pointer are equipped with sender device, and rotating disc or pointer are connected on rotary wing wheel (1).Described inductor (3) is arranged on the circumference of rotating disc or pointer rotation, and inductor (3) is contactless with rotating disc or pointer (2).
Described rotary wing wheel is the rotary wing wheel of existing rotor water gauge, and this rotary wing wheel, can initiating rotation under the pressure lower than 0.02MPa according to the detection performance data of water meter.
Described sender device is magnet steel.
Described inductor is the magnetic induction device corresponding with the sender device that is contained in rotating disc or pointer, as tongue tube, Hall element etc., or is photoelectric device.
In the time that the fluid of utmost point low-pressure is flowed through outer shell cavity, rotary wing wheel rotation, rotary wing wheel driven rotary dish or pointer rotation, rotating disc or pointer often rotate a circle, sender device on it just triggers inductor one time, an electric pulse of inductor output, this electric pulse is pipeline inner fluid flow signal, for automated system collection.
