Respectively No.1 control valve 3.1 and No. two control valves 3.2, No.1 control valve 3.1 are hand control valve, and No. two control valves 3.2 are
Solenoid electric valve.Wherein the outlet end of No.1 control valve 3.1 connects the arrival end of the choke tube 5, and No. two control valves 3.2 go out
Mouth end and the outlet end of the choke tube 5 pass through the venturi tube inlet end that hose is connected in test section 6 respectively.The choked flow
The lumen middle section of pipe 5 is contracting cavity configuration (Fig. 6, Fig. 7 .1, shown in 7.2).
As Fig. 1 to Fig. 3, Fig. 5 .1 to 5.2 shown in, the Response Division 4 includes the attachment base 41 connecting with the four-way pipe 2.
The attachment base 41 is equipped with axial cavity, is equipped with strain component 42 at the middle part of cavity, the strain component 42 includes elasticity
Film 421 and the foil gauge 422 being fixed in elastic membrane 421, foil gauge 422 are connected with outer lead road.Elastic membrane 421 is by attachment base

No. two control valves 3.2, Response Division 4 and amplifier 5 are connected to the control assembly (containing microprocessing unit pair
The signal that the signal and amplifier of Response Division transmission are incoming is analyzed and processed).The control assembly can be according to the strain
The variation of piece 422 specifically sets and controls the opening and closing of No. two control valves 3.2.The control assembly can be according to sensing element
The air flow condition detected, after setting and controlling No. two unlatchings of control valves 3.2, the time being closed again, usually after expiration
Phase just controls No. two control valves closure having been switched on when sensing element can't detect the air-flow flowed through.In other words, when
Internal pressure deformation quantity caused by foil gauge reach control assembly setting open No. two control valves in the range of after, control assembly
No. two control valves are then driven to be opened, even if no longer making No. two in control assembly setting in the internal pressure that (each) end of breath is formed
In the range of control valve is opened, No. two control valves will not be closed automatically, i.e., at this time No. two control valves still it is electric, in leading
Logical state.The control assembly can receive the signal that the amplifier 66 transmits and be handled, and calculate the real-time of exhaled gas
Pressure and expiratory gas flow.
After the gas of exhalation enters four-way pipe, certain internal pressure is formed in the lumen of four-way pipe, is deformed elastic membrane,
And then foil gauge is deformed, change its resistance value, the size for forming internal pressure is big by the diameter of expiration ability and choke tube contracting cavity configuration
Small influence.Internal pressure is different, and the deflection (resistance value) of foil gauge is different, and foil gauge, to assembly is controlled, is being controlled by connection
Assembly can be according to the opening and closing of variation No. two control valves of control of the resistance value size of foil gauge.So the real value of foil gauge resistance value is
It is corresponding with the real value of breath pressure, the real value of breath pressure thus can be obtained after control assembly processing, or even exhale
The waveform diagram of atmospheric pressure variable condition.Before No. two control valves are not turned on, the real-time change state of foil gauge, which is able to reflect, is exhaled
The physiological parameter information of gas original state.
Under normal circumstances, when making choke tube independent role, in the internal pressure that four-way tube cavity is formed, become caused by foil gauge
Shape amount, the interval range that can not drive No. two control valves to be opened with the foil gauge deflection of setting are overlapped.I.e. by choke tube
Effect perform physical exercise as preliminary stage, perform physical exercise by the automatic open close of No. two control valves as stage phase in later period, thus
Later period, which manually adjusts No.1 control valve, is closed it.Specific explanation is as follows:
The limit section (being assumed to be 0.1a to 1a) of foil gauge resistance value is divided into multiple sections, concretely 0.1a-
0.35a, 0.35a -0.65a, 0.65a -0.8a, 0.8a -0.95a etc., end value belongs to next interval range.The forging of early period
During refining, the internal pressure that choke tube is formed makes foil gauge deformation occurs that corresponding resistance value is less than 0.35a, so as worked as resistance value
When in the section for being less than 0.35a, what No. two control valves were always closed (has one to set the tone if the choked flow of choke tube itself acts on
Between main plot, then under different conditions, corresponding upper limit resistance value has multiple, it is possible to which opposite setting keeps foil gauge resistance value small
When 0.25a or 0.35a or 0.45a, what No. two control valves were always closed, i.e., No. two control valves are in >=0.45a when Fang Kaiqi).
According to observation, the analysis to training progress, it is determined whether enter the training stage in later period, close No.1 control valve.
In short, deformation occurs for foil gauge, when change in resistance is within the scope of which kind of, just make No. two control valves startings, specifically
It is to be needed according to the people and the time and different by controlling assembly flexible modulation.Such design, which can not only be known in training process, exhales
Atmospheric pressure state value, and the device can be according to the people and the time set, guarantee training of safety, be effectively performed.
