Specifically describe
Fig. 1 schematically shows the exemplary overvoltage helmet 10 used in pressurized environment 11, and this overvoltage helmet
Including overvoltage recovery valve the 12, first and second supply line 14, recovery line 16 and actuator 18.Such as, pressurized environment 11 can
To be drifter drill for underground environment.
First supply line 14 and the second supply line 14 are connected to the overvoltage helmet 10 to be supplied for user by the helmet 10
Respirable gas.The overvoltage helmet 10 also provides for pressure in the helmet 10, and this pressure is higher than the pressure outside the helmet, such as, 2cm
Water column, to ensure that the gas not from pressurized environment 11 enters in the helmet 10 if it occur that leakage.At some embodiments
In, overvoltage can be high high to about 8cm water from about 0.5cm water or the high any amount high to about 5cm water of about 0.6cm water.
Recovery line 16 is connected to the overvoltage helmet 10 at overvoltage recovery valve 12.Overvoltage recovery valve 12 receives user's exhalation
Gas, and the interior gas breathed out of valve can be allowed to be breathed out in flowing out valve by recovery line 16 or valve 12 can be allowed
Gas flow out excess pressure valve 12 to pressurized environment 11.
Recovery line 16 is connected to actuator 18, be then attached to reclaim or dump system (not shown), this recovery or turn
Storage system can be user filtering, clean and/or remix breathing gaseous mixture.This system may be positioned in pressurized environment 11
In near user, or can be located on the ground away from user, this space is more freely available.This system can be normal recovery
Device or facility, workman's breathing gas retracting device or facility or external exhaust port or dump apparatus or facility.Actuator 18
Can be used as safety measure so that the pressure from the helmet 10 to be gradually decrease to take exhaled gas to pressure necessary to outside.
Fig. 2 a shows that the front view of overvoltage recovery valve 12, Fig. 2 b show that the side view of overvoltage recovery valve 12, Fig. 2 c show
Go out the exploded view of overvoltage recovery valve 12, and Fig. 2 d has shown the cross-sectional view of overvoltage recovery valve 12.
Overvoltage recovery valve 12 includes entrance 19, recovery outlet 20, local atmospheric outlet 22, switch 24, housing 26, has
The spring 28 of spheroid 30, lining 32, air bleeding valve 34, chamber 35, threaded collar 36, dividing plate 38, there is the lid of local atmospheric outlet 22
40 and there is the folder valve gap 42 of securing member 44.Switch 24 parts include threaded collar 46, switching ring 48, spacer 50 and plug-in unit
52.Reclaim outlet 20 to include: couple flexible pipe 54, O 56, outlet valve 58, spring 60, spring base 62, circlip 64 and have
The safety plate 66 of securing member 68.
Housing 26 can be the housing of universal class, it is allowed to be connected to many different types of helmets 10.Housing 26 can wrap
Including coupling part 25, this coupling part can include the screw thread for being connected to the helmet 10.
Switch 24 is positioned near the entrance 19 of valve 12, and the gas in control valve 12 whether flow out recovery outlet 20 or
Person flows out local atmospheric outlet 22.Switch 24 is rotated by the part considering the switching ring 48 using plug-in unit 52 and controls this
Action.This rotation can be manually completed by user.
Air bleeding valve 34 is positioned at housing 26, and combines spring 28 and pressure that spheroid 30 controls in the helmet 10 (sees figure
1).Power on spring 28 controls the overvoltage degree within the helmet 10.
During use, air bleeding valve 34 can move in housing 26, when overvoltage is overcome, it is allowed to is entered by entrance 19
The exhaled gas of valve flows to chamber 35.When switch 24 is provided so that gas can flow out recovery outlet 20, air bleeding valve
34 move up to allow gas in chamber 35.Dividing plate 38 is also bent upwards, and these motions cause reclaiming outlet
In 20, other motions of parts, such as, tilt or rotate, and this allows gas to flow out from chamber 35 and reclaims outlet 20, and this gas will
Enter recovery line 16 (seeing Fig. 1).
When switch 24 is provided so that gas flows out local atmospheric outlet 22, in local atmospheric outlet 22 and lid 40
Hole alignment.Therefore, once exhaled gas enters valve 12 by entrance 19, in the hole of the outlet 22 in switching ring 48 and lid 40
The alignment in hole allows gas to flow out in the local air outside the helmet 10.
Overvoltage recovery valve 12 allows gas to be recovered in the case of requiring overvoltage, such as, big in dry toxicity or overvoltage
In gas.Generally, the recovery valve in past is only capable of the pressure in inner helmet equal to the pressure outside the helmet in local air
In the case of work, and suitably effect can not be played with the overvoltage in the helmet 10 or maintain the overvoltage in the helmet.In underground
The gas used in operating characteristics can include helium and oxygen and sometimes with the expensive gaseous mixture of nitrogen.Owing to helium is the most high
Expensive and be difficult to obtain in some places in the world, it is possible to reclaiming and recycle gas can be the most valuable.Such as shown in Fig. 1
Recovery system by using overvoltage recovery valve 12 to cause to save and re-use the about 60%-90%'s that uses during operation
Gas.
Additionally, it is longer to use overvoltage recovery valve 12 and gas recovery system that workman can be allowed to stagnate at underground construction scene
Time.In the system in past, workman must return to ground continually for new breathable gas.Due to this return warp
Often need decompression, the most time-consumingly.By using overvoltage recovery valve 12 can maintain the overvoltage during operation, gas can be recovered,
Clean and reuse, eliminate or reduce in order to supplementary breathable gas returns to the needs on ground.
The switch 24 of overvoltage recovery valve 12 allows the gas in valve 12 by reclaiming outlet 20 or by local air
Outlet 22 outflow, makes the valve 12 can be adaptive and be safely used in many different situations.This can allow user to be prone to from an outlet
Change and export to another, and can ensure that any fault in recovery system, actuator 18 or recovery line 16 or problem will not
The user of the harm overvoltage helmet 10.
By making overvoltage recovery valve 12 be combined with the shell body 26 of standard, overvoltage recovery valve 12 can be with the mark being currently sold
The accurate overvoltage helmet works together.When used gas is reclaimed in expectation, this can eliminate and replace the whole overvoltage helmet 10
Need.
Although describing the present invention with reference to illustrative embodiments, it would be appreciated by persons skilled in the art that
In the case of without departing from the scope of the present invention, various change and available equivalents can be carried out its element is replaced.This
Outward, in the case of without departing substantially from the elemental range of the present invention, multiple amendment can be made, so that particular case or material are suitable to this
The teaching of invention.Accordingly, it is intended to make the present invention be not limited to disclosed detailed description of the invention, but the present invention will include falling
