The reducer 3 is connected with the cylinder 1 by a mechanical crank 5. Two electromagnetic valves 6, a counter 7 and a power supply switch 9 are arranged on the front panel. The electromagnetic valve 6 is connected with the cylinder 1 by a hose 8. The power supply switch 9 is connected with the motor 2. The counter 7 is connected with the reducer 3. A controlling box 4 is arranged on the back panel. The controlling box 4 is connected with the electromagnetic valve 6 by a signal wire. The utility model has simple and novel structure, the respiratory rate is 20 to 24 times per minute, which satisfies the detection requirement of national standard GB2626-2006 to dead space item.
Description
Technical field
The utility model relates to a kind of breathing simulator that is used to detect protective respirator dead space project.
Background technology
The method that former industry standard LD29-1992 " anti-dust respirator ", standard GB/T2626-1992 " self-suction dust filter mask general technical specifications " detect protective respirator dead space project is with pouring water, irritate micromicrofarad.This kind method exists bigger human error factor, and technological means falls behind.GB2626-2006 " protective respirator suction-self filtering type against particle respirator " national Specification of new issuing and implementation in 2006 the protective respirator method that detects the dead space project be to adopt the carboloy dioxide analysis method.The GB2626-2006 standard has proposed the principle requirement to the checkout equipment of dead space project, the concrete structure of breathing simulator is not made an explanation.
Summary of the invention
The objective of the invention is provides a kind of breathing simulator that satisfies examination criteria for adapting to the regulation of GB2626-2006 national standard about the dead space test item.
Technical solution of the present invention is: a kind of breathing simulator that detects the dead space project, form by housing, front panel, rear board, and adopt steel frame that housing is divided into two parts up and down in enclosure interior; Bottom in housing is provided with motor and reductor, and motor is connected by belt with reductor, and the top in housing is provided with twin-tub synchronous piston formula cylinder, and reductor is connected with twin-tub synchronous piston formula cylinder by mechanical crank; Two magnetic valves, a counter, a power switch are installed on the plate in front, and magnetic valve links to each other with cylinder by flexible pipe, and power switch connects motor, the unlatching of control motor, and counter connects reductor, calculates respiratory rate; On the plate control cabinet is set in the back, control cabinet is connected with magnetic valve by holding wire, the unlatching of control magnetic valve.
Beneficial effect of the present invention is as follows: the breathing simulator that the utility model provides is simple in structure, novel, and respiratory rate is: 20～24 times/min, can satisfy the detection requirement of GB GB2626-2006 to the dead space project.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
A kind of breathing simulator that detects the dead space project is made up of housing, front panel, rear board, adopts steel frame that housing is divided into two parts up and down in enclosure interior; Bottom in housing is provided with motor 2 and reductor 3, and motor 2 and reductor 3 are connected by belt, and the top in housing is provided with twin-tub synchronous piston formula cylinder 1, and reductor 3 is connected with cylinder 1 by mechanical crank 5; Two magnetic valves of A, B 6, counter 7, a power switch 9 are installed on the plate in front, and magnetic valve 6 links to each other with cylinder 1 by flexible pipe 8, and power switch 9 connects motor 2, the unlatching of control motor 2, and counter 7 connects reductors 3, the calculating respiratory rate; Control cabinet 4 is set on the plate in the back, and control cabinet 4 is connected with magnetic valve 6 by holding wire, the unlatching of control magnetic valve 6.
As Fig. 4, detect the process of dead space project with this breathing simulator:
Protective respirator is worn on the head mould, turns on the power switch 8, start and breathe simulator, motor 2 drives mechanical crank 5, and crank 5 promotes twin-tub synchronous piston formula cylinder 1 again, produces to exhale, inhale motion.And then, will exhale, inhale motion and transmit downwards by two magnetic valve 6 synchronization actions of control cabinet 4 control A, B.When twin-tub synchronous piston formula cylinder 1 (A, B twin-tub) during simultaneously to left movement (being called air-breathing), the inlet valve gate open of A, B magnetic valve 6, mist advances the B cylinder of twin-tub synchronous piston formula cylinder 1 by B magnetic valve 6, head mould place gas enters the A cylinder of twin-tub synchronous piston formula cylinder 1 by A magnetic valve 6 simultaneously, thereby finishes the suction condition of breathing simulator; As the A of twin-tub synchronous piston formula cylinder 1, (be called expiration) when the B twin-tub moves right simultaneously, the outlet valve gate open of A, B magnetic valve 6, the B cylinder of twin-tub synchronous piston formula cylinder 1 is exported to head mould with mist by flowmeter, simultaneously twin-tub synchronous piston formula cylinder 1 is exported to capnograph with a gas part, another part discharging is finished the expiration state thereby breathe simulator.So circulation a period of time, read the data on the capnograph after waiting to stablize.
