Abstract
The utility model relates to a flow switch sensor. A magnet 2 and a reed pipe 3 are arranged in an external connection block 1, and a magnet 5, a guard sheet 8 and a balancing weight 4 are coaxially installed on a bracket 7 fixed on an airflow seat 11 in a pipe joint 6. When airflow passes through a pipeline, the guard sheet 8 can be pushed to drive the magnet 5 to rotate to change the original polarity of the magnetic 5, which corresponds to the polarity of the magnet 2, therefore the reed pipe 3 can be opened and closed.
Description
The utility model relates to a kind of flow switch transducer.
Existing flowmeter, flowmeter, flow sensor all are used for measuring or detecting flow size and quantity.But common flow sensor is used for also having deficiencies such as reaction is slow, sensitivity is low, complex structure, the fluid pressure loss is big, volume is big, price is expensive as the flow switch transducer of qualitative detection except that must joining certain circuit.
The purpose of this utility model is the deficiency that exists in the above-mentioned background technology in order to overcome, and provide a kind of simple in structure, highly sensitive, the fluid pressure loss is little, the qualitative detection senser that has or not air communication to cross in the decidable pipeline.
To achieve these goals, the scheme that the technology that the utility model proposes solves: in pipe joint and external, between opposite polarity two magnetic patch a reed capsule is set, magnetic patch, catch and balancing weight are rack-mount by axle, airflow hole on the diversion seat is corresponding with the position of catch, and reed capsule places outside the pipe joint wall.The reed capsule axis is orthogonal with axle, and with the parallel axes of magnetic patch, the two ends of axle are provided with top.Pipe joint and external are the non-magnetizer material and make.
Fig. 1: structural representation of the present utility model.
Fig. 2: the cooperation schematic diagram of support, catch, magnetic patch and balancing weight.
Below with reference to accompanying drawing the utility model is done a detailed description.
As shown in Figure 1 and Figure 2, be provided with diversion seat 11 in the pipe joint made from non-magnet material such as copper, aluminium 6, fix a support 7 on the diversion seat 11, magnetic patch 5, balancing weight 4 and catch 8 are by axle 10 coaxial being installed on the support 7.In order to improve its sensitivity, the moment of torsion that the weight of catch 8 produces should be slightly larger than the moment of torsion of the weight generation of balancing weight 4, and axle 10 two ends that contact with support 7 are provided with top.Diversion seat 11 is provided with a trumpet-shaped airflow hole 9, and this airflow hole 9 is corresponding with the position of catch 8.Also connect one external 1 outside pipe joint 6, external 1 internal fixation has strip magnet 2 and reed capsule 3.External 1 material also is a non-magnet material.Reed capsule 3 and magnetic patch 2 parallel placements, and orthogonal with axle 10.
Operation principle of the present utility model is: do not have air communication out-of-date in the pipeline, catch 8 is in extreme lower position, and the magnetic axis of the magnetic axis of magnetic patch 5 and magnetic patch 2 is perpendicular, and the contact in the reed capsule 3 is in off-state.When having gas to pass through pod apertures 9 in the pipeline, air-flow promotes catch 8 and drive magnetic patch 5 coaxial mounted with it and balancing weight 4 and rotates 90 ° around axle 10, this moment magnetic patch 5 by original when static the 3 vertical position whiles of magnetic axis and reed capsule also rotated 90 °, and with reed capsule 3 parallel axes.Because after magnetic patch 5 rotated 90 °, polarity was opposite with the magnetic axis of magnetic patch 2 is parallel for its magnetic axis, by the interaction between two magnetic patch, 2,5 magnetic fields, can make reed capsule 3 conductings, the signal that has air communication to cross just can reach robot control system(RCS).
The utility model has the advantage of: utilize the position of the size change catch of throughput, cause magnetic field Change, reed capsule is between magnetic patch and be subjected to the effect of changes of magnetic field and realize break-make, its sensitivity Higher, reaction speed is very fast. Because catch, balancing weight and the top design of axle head can further improve Its sensitivity, the pressure loss of fluid also can reduce. This sensor construction is simple, small volume, and is available In detecting pipeline, there is airless to pass through and as the sensing element in the robot control system(RCS). Because this sensor Sensing element is placed in the pipeline, and conversion element is placed in outside the pipeline, has reduced the gas leakage point, and is especially suitable In detection poisonous, inflammable gas.
