Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment 1:(counting butterfly valve), as shown in Figure 1-2, a kind of counting butterfly valve, including valve body 1, valve body 1 is metal structure, the counting display device 2 being arranged on valve body 1, as in figure 2 it is shown, counting display device 2 includes being coaxially disposed with valve body 1 and with the pointer 21 of dish plate 3 synchronous axial system, the Hall element GH being arranged on pointer 21, be arranged on valve body 1 and be in the Magnet 22 of dish plate 3 open mode position for Hall element GH detection, be connected Hall element GH in order to transmit the second optic coupling element U2 of signal, to connect the enumerator 23 of the second optic coupling element U2 outfan.The light-emitting component that is additionally provided with on valve body 1 to provide the illuminator 4 of counting display device 2 secondary light source, illuminator 4 to include that power supply is connected with power supply, it is series on light-emitting component the switch element 6 in order to control current supply circuit switching.Light-emitting component is LED string 5 or fluorescent lamp.The present embodiment is preferred with LED string 5.Switch element 6 is press button SB.
Work process: working power is 12V power supply, after energising, enumerator 23 is started working counting, Hall element is arranged on the tip of instruction, near Magnet 22 when, the input of optocoupler is exported optical signal, is coupled to the outfan of the second optic coupling element U2, thus enumerator 23 counts, the when of night, manually press the button switch SB so that LED lamplight is illuminated.
Embodiment 2:(counting butterfly valve), as shown in Figure 3, switch element 6 include detecting human body whether near and export the pyroelectric infrared sensor 61 of corresponding control signal, connect the first optic coupling element U1 of pyroelectric infrared sensor 61 outfan, connect relay K M of the first optic coupling element U1 outfan, the normally opened contact of relay K M is series at the current supply circuit of light-emitting component.It is additionally provided with adjustable resistance Rp1 between Hall element GH and the second optic coupling element U2.Current-limiting resistance R1 also it is in series with on the current supply circuit of light-emitting component.It should be understood that pyroelectric infrared sensor 61 includes housing, optical filter, field effect transistor Q11 and pyroelectricity element；Housing is provided with through hole, and optical filter is connected in through hole；Field effect transistor Q11 and pyroelectricity element are positioned at the enclosure interior of pyroelectric infrared sensor 61；Pyroelectricity element is coupled between the grid of field effect transistor Q11 and ground end.Radiated by optical filter sensing external heat.The Main Function of optical filter is only to allow wavelength infrared ray (Infrared wavelength that human body sends) about 10 μm to pass through, and light, sunlight and other radiation is filtered, with the interference that suppression is extraneous.Infrared induction source is generally made up of two pyroelectricity elements in series or in parallel, the electrode of the two pyroelectricity element is contrary, ambient background radiation almost has identical effect to two pyroelectricity elements so that it is the pyroelectric effect of generation is cancelled out each other, and output signal is close to zero.In once having people's intrusion detection region, human infrared radiation is focused on by partial mirror, and is received by pyroelectricity element, owing to angle is different, the heat that two panels pyroelectricity element receives is different, and pyroelectricity energy is the most different, can not be completely counterbalanced by, after treated processing of circuit, export control signal.Pyroelectric effect is similar to piezoelectric effect, refers to cause the phenomenon of plane of crystal electric charge due to the change of temperature.Pyroelectric infrared sensor 61 is made up of ceramic oxide or piezolectric crystal unit, electrode is made on two surfaces of element, when in the range of Sensor monitoring, temperature has the change of △ T, pyroelectric effect can produce electric charge △ Q on two electrodes, produces a faint voltage △ V the most between electrodes.Owing to its output impedance is high, field effect transistor Q1 is had to carry out impedance transformation in the sensor.Produced by pyroelectric effect, electric charge △ Q can be combined by the ion in air and disappear, and i.e. when ambient temperature-stable is constant, △ T=O, sensor is without output.Human body or the bigger animal of volume have constant body temperature, general at 37 degree, so the infrared ray about specific wavelength 10 μm can be sent, when human body enters detection zone, because human body temperature and ambient temperature have difference, infrared ray about 10 μm of human-body emitting gathers on infrared induction source (pyroelectricity element) after being strengthened by Fresnel lens optical filter, infrared induction source will lose charge balance when receiving human infrared radiation, outwards discharge electric charge, and then produce △ T and △ T circuit to the periphery is exported, subsequent conditioning circuit just can produce biological personnel after processing after testing and detect signal.
Work process: have human body near when, pyroelectric infrared sensor 61 output signal so that relay K M action, so that LED string 5 is illuminated.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
