Embodiment
According to shown in Figure 1; Housing 1 is a hexahedron structure; Be connected with panel 1.0 in the front portion of housing, power switch 2, digital display screen 3, positive negative pressure selector button 4 and air pressure configuration switch 5 are installed on panel successively, the air pressure configuration switch is installed on the air pressure configuration switch dials and turn round 5.1.
According to shown in Figure 2, be connected with backboard 1.00 at the rear portion of housing, standard pressure output interface 7, negative pressure source of the gas input interface 8 and malleation source of the gas input interface 9 are installed on backboard, in a side of backboard external power supply socket 6 is installed.
According to shown in Figure 3; In housing 1; The power lead 1.1 of external power interface 6 is connected with transformer 1.3 and is connected with power panel 1.4 again, and power switch 2 is connected with operation program plate 1.6 with selector button 4, air pressure configuration switch 5, the automatically controlled plate 1.5 of air pressure toggle switch respectively.The wireway of negative pressure source of the gas input interface 8 and malleation source of the gas input interface 9 is communicated with air-capacitor tube 1.7 through thermostat 1.2; Be connected with standard pressure output interface 7 again; Be connected with baroceptor 1.8 simultaneously; Baroceptor is connected with operation program plate 1.6 circuit, and the operation program plate is connected with digital display screen 3 circuit.
The utility model is used to produce the standard positive and negative air-pressure, detects as air pressure contrast and air pressure.
The use of the utility model:
In use, malleation source of the gas input interface is connected with supercharge pump, and negative pressure source of the gas input interface is connected with aspiration pump, and external power supply socket is electrically connected with the city.
When standard malleation or negative pressure source of the gas need be provided, turn on the power switch, circuit is powered on, power supply exchanges the direct current that becomes low-voltage through transformer with 220 volts, supplies with each consuming parts, makes it work.
When needs provided the malleation standard pressure, pressing the air pressure SS was the malleation position, simultaneously through stirring air pressure configuration switch toggle; Set required standard pressure value, open supercharge pump, in the air-capacitor tube, import gas through thermostat; Pneumatic pipe cleaner in the air-capacitor tube is crossed sensor and is converted electric signal to and be input in the control panel; When reaching setting air pressure, air pressure signal feeds back to the supercharge pump driving circuit, stops supercharge pump work.When air pump was worked, the gas of in air-capacitor, being imported remained under the design temperature through thermostat, was unlikely to realize the gas constant temperature and pressure because temperature inversion causes air pressure change.When input gas in the air-capacitor tube, the numeral of air pressure shows through digital display screen always.When reaching setting air pressure, just through standard pressure output interface outputting standard air pressure, air feed presses examination criteria to use.
When needs provided the negative pressure standard pressure, what be connected with negative pressure source of the gas input interface was aspiration pump, was negative pressure state in the air-capacitor tube.
