Fig. 1 is the structural representation of respirator pneumatic control component.
In accompanying drawing: 1-self-complementary connecting hose; 2-quantitative connecting hose; 3-alarm; 4-manual air compensating valve; 5-pressure reducer; 6-hand is mended connecting hose; 7-adjustable metering device; 8-middle pressure pipe; 9-safety valve; 10-high-voltage and current-limitation device; 11-pressure duct; 12-valve body; 13-gases at high pressure joint.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, respirator pneumatic control component, comprises alarm 3, high-voltage and current-limitation device 10, adjustable quantitative apparatus of oxygen supply 7 and valve body 12.Manual air compensating valve 4, pressure-reducing valve 5 and safety valve 9 are set on valve body 12.
Wherein, oxygen intake, high pressure branch road I, high pressure branch road II and high pressure branch road III are set on valve body 12.High pressure branch road I, high pressure branch road II and high pressure branch road III all communicate with oxygen intake, and the air inlet of pressure-reducing valve 5 communicates with oxygen intake, and filter is set in oxygen intake.Manual air compensating valve 4 is connected in high pressure branch road I, and alarm 3 is connected in high pressure branch road II, and the air inlet of high-voltage and current-limitation device 10 is connected in high pressure branch road III, and the gas outlet of high-voltage and current-limitation device 10 connects a gases at high pressure joint 13.The air inlet of safety valve 9 and adjustable quantitative apparatus of oxygen supply 7 communicates with in the pressure-reducing chamber of pressure-reducing valve 5 respectively.Fast three-way body and the self-complementary connecting hose 1 of inserting after adjustable quantitative apparatus of oxygen supply 7 gas outlet Zhong mono-tunnel access alarms, the quantitative connecting hose 2 of separately leading up in adjustable quantitative apparatus of oxygen supply 7 gas outlets is connected with respirator actuating unit.
While using this respirator pneumatic control component, gas enters pressure reducer 5 after filtering from oxygen intake, in valve body 12, carry out shunt, the high-pressure side that one road gases at high pressure enter alarm 3 provides high pressure to alarm 3, one road gases at high pressure enter manual air compensating valve 4, after manual air compensating valve 4 is opened, are converted into low-pressure gas; One road gases at high pressure enter high-voltage and current-limitation device 10, enter pressure duct 11 and provide air pressure to air gauge after high-voltage and current-limitation device 10 current limlitings.In pressure-reducing chamber, post-decompression gas is medium pressure gas, one tunnel enters safety valve 9, after pressure reducer 5 breaks down the medium pressure gas superpressure of exporting, safety valve 9 is opened pressure pressure in pressure releases assurance, and the prompt facility of simultaneously sounding breaks down, and the prompting personnel of wearing withdraw deathtrap.One road medium pressure gas enters adjustable quantitative apparatus of oxygen supply 7, has the function of medium pressure gas shunt in its main body.Medium pressure gas is divided into two-way one tunnel to be entered fast after alarm 3 and inserts three-way body and provide middle pressure alarm gas and self-complementary connecting hose 1 for alarm.The oxygen that another road medium pressure gas arrives the 1.4～1.9L/min flow requiring after adjustable quantitative apparatus of oxygen supply 7 is reconciled is connected with respirator actuating unit by quantitative connecting hose 2; Medium pressure gas through adjustable quantitative apparatus of oxygen supply 7 also can be mended connecting hose 6 input manual air compensating valves 4 by hand.
