Abstract
An automatic audible and visual alarm type pressure gauge comprises a shell, an electric contact pressure gauge and an alarm circuit. The electric contact pressure gauge and the alarm circuit are mounted inside the shell, the alarm circuit comprises a battery, a switch, an integrated block, a resistor, a light emitting diode and a loudspeaker, a movable contact end of the electric contact pressure gauge is connected with a cathode of the battery, an anode of the battery is connected with one end of the resistor and further connected with a power source anode end of the integrated block, the other end of the resistor is connected with an anode of the light emitting diode, the cathode of the light emitting diode is connected with a power source cathode end of the integrated block, a pressure low limit contact end of the electric contact pressure gauge is connected with a pressure high limit contact end of the electric contact pressure gauge, and an output end of the integrated block is connected with the loudspeaker. Compared with the prior art, the automatic audible and visual alarm type pressure gauge has the advantages of simple structure, convenience in use and capability of timely raising audible and visual alarms when pressure is excessively high or low.
Description
Technical field
The utility model relates to a kind of tensimeter, is specifically related to a kind of automatic sound-light alarm formula tensimeter.
Background technology
At present, generally all be that conventional tensimeter is installed on the pressure vessel on oil field gathering and transportation pumping plant, the collector and delivery pipe,
The variation of artificial inspection trips pressure judges whether gathering system is normal, in time gets rid of the production fault again; Because artificial inspection is the free cycle, interval time if any hypertonia or low excessively situation, the operator on duty just can not in time find; Bury the hidden danger of pernicious industrial accident for this reason; Suppress quick-friedly like pressure vessel blast, gathering line, electric equipment burns, and similar accidents such as casualties happen occasionally.
The utility model content
The purpose of the utility model is exactly the defective that exists to prior art, and a kind of automatic sound-light alarm formula tensimeter is provided.
Its technical scheme is: comprise housing, electro connecting pressure gauge and warning circuit, electro connecting pressure gauge and warning circuit are installed in enclosure interior.Said warning circuit is made up of battery, switch, integrated package, resistance, light emitting diode and loudspeaker; The moving contact end of electro connecting pressure gauge is connected with the negative pole of battery through switch; The positive pole of battery is connected with an end of resistance and the power positive end of integrated package; The other end of resistance is connected with the positive pole of light emitting diode; The negative pole of light emitting diode and the power-of integrated package are extreme, the high limit of the pressure tip side of the pressure lower bound tip side of electro connecting pressure gauge and electro connecting pressure gauge is connected, and the output terminal of said integrated package is connected with loudspeaker.
Wherein, said housing is the explosion-proof pressure watchcase.Said integrated package is a music integrated chip.Said light emitting diode is seven color flicker light emitting diodes.
The utility model has simple in structure, easy to use and can or cross the advantage that low situation is in time sent sound and light alarm to hypertonia compared with prior art.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, a kind of automatic sound-light alarm formula tensimeter comprises housing 1, electro connecting pressure gauge 2 and warning circuit 3, and electro connecting pressure gauge 2 is installed in housing 1 inside with warning circuit 3.Warning circuit 3 is made up of battery, K switch, ic chip, resistance R, light emitting diode D and loudspeaker L; The moving contact end P0 of electro connecting pressure gauge 2 is connected through the negative pole of K switch with battery DC; The positive pole of battery DC is connected with an end of resistance R and the power positive end of ic chip; The other end of resistance R is connected with the positive pole of light emitting diode D; The negative pole of light emitting diode D and the power-of ic chip are extreme, the high limit of the pressure tip side P2 of the pressure lower bound tip side P1 of electro connecting pressure gauge 2 and electro connecting pressure gauge is connected, and the output terminal of ic chip is connected with loudspeaker L.Housing 1 adopts the explosion-proof pressure watchcase.Ic chip is a music integrated chip.Light emitting diode D is seven color flicker light emitting diodes.
During operation; The test side of electro connecting pressure gauge in this device 2 is installed on pipeline to be detected or the container; Open K switch, when pressure just often, the high limit of the pressure lower bound tip side P1 in the electro connecting pressure gauge 2 and the pressure of electro connecting pressure gauge tip side P2 does not all connect with moving contact end P0; At this moment, ic chip and light emitting diode D all can not get power supply and do not send signal; When tested hypertonia (or low excessively), high limit tip side P2 of the pressure in the electro connecting pressure gauge 2 (or pressure lower bound tip side P1) and moving contact end P0 connect, and at this moment, ic chip and light emitting diode D all obtain power supply and send the sound and light alarm signal.
