Abstract
The utility model discloses a mechanical structure of a pipeline card metering switch. The mechanical structure of the pipeline card metering switch comprises a card holder, a singlechip, a display screen, a pressure tap, a pressure sensor, a shell, an electromagnetic valve, a throttle pipe and a water pipe, wherein the throttle pipe is installed at the tail end of the card metering switch; the electromagnetic valve is serially connected with throttle pipe; the two ends of the electromagnetic valve are connected with the water pipe; the pressure tap is installed at the two ends of the throttle pipe; the pressure sensor is installed in the middle of the pressure tap; the display screen is installed on the top of the shell; the singlechip is installed on the lower part of the display screen; the card holder is installed on one side, near the display screen, of the top of the shell; the display screen, the pressure sensor and the electromagnetic valve are in communication connection with the singlechip. Running water forms pressure difference at the throttle pipe, the pressure sensor obtains a pressure signal from the pressure tap and transmits the pressure signal to the singlechip, and the singlechip controls on and off of the electromagnetic valve according to card information, thus achieving card metering.
Description
Technical field
The utility model relates to a kind of physical construction of pipeline plug-in card metering switch.
Background technology
China is one of 13 countries that water resource is the poorest per capita in the whole world.Saving water resource is the extremely urgent problem that needs the whole society to pay close attention to.The measurement of flow is with to be controlled at every field all extremely important.Existing flow metering mode is varied, and their principle has electromagnetism, ultrasound wave, and turbine, optical fiber, pressure transducer etc., ultrasonic type and turbine type are widely used in every field.But turbine type has a rotary blade directly to contact, hinder liquid flow with liquid, its overload capacity is not strong, and the impact of liquid body quality; Although supercritical ultrasonics technology there is no direct contacting with fluid but its insufficient sensitivity is high, be difficult to detected obtaining for low speed, low discharge; Electromagnetic type is conventionally only effective to conductive liquid; Pressure type has one to hinder part in stream pipe conventionally, and tiny flow quantity is also difficult to detect.
Utility model content
The utility model, for solving the deficiencies in the prior art, provides a kind of physical construction of pipeline plug-in card metering switch.
The technical solution adopted in the utility model is: a kind of physical construction of pipeline plug-in card metering switch, comprises card-inserted device 1, single-chip microcomputer 2, display screen 3, pressure pipe 4, pressure transducer 5, housing 6, solenoid valve 7, choker-line 8 and overflow pipe 9; Choker-line 8 is arranged on the end of plug-in card metering switch, and solenoid valve 7 and choker-line 8 are serially connected, and two ends are connected with overflow pipe 9; Pressure pipe 4 is arranged on the two ends of choker-line 8, and pressure transducer 5 is arranged on the centre of pressure pipe 4; Display screen 3 is arranged on the top of housing 6, and single-chip microcomputer 2 is arranged on the bottom of display screen 3; Card-inserted device 1 is arranged on the top of housing 6, near a side of display screen 3; Described display screen 3, pressure transducer 5 and solenoid valve 7 communicate to connect with single-chip microcomputer 2; Flowing water is poor at choker-line 8 place's mineralization pressures, and pressure transducer 5 obtains pressure signal from pressure pipe 4 and passes to single-chip microcomputer 2, and single-chip microcomputer 2, according to the break-make of plug-in card information control solenoid valve 7, measures thereby realize plug-in card.
The beneficial effects of the utility model are: the utility model has designed a kind of physical construction of pipeline plug-in card metering switch, and structural design is simple, reasonable.Can be arranged on easily on pipeline.
