Detailed description of the invention
Refer to Fig. 1 ~ Fig. 4.The vapour-pressure type vest of the aeration disclosed by the present invention, it is a kind of vest 10 connecting body up and down and be provided with head space 11.This vest 10 is provided with one and penetrates mouth 16, penetrates in this vest 10 for staff.This penetrates mouth 10 and is outside equipped with diaphragm seal 162 and blocks air and enter in vest 10.This penetrates mouth 16 and is provided with slide fastener 161, closes or opens this penetrate mouth 16 by slide fastener 161.Sealing sheet 162 comprises left and right two cramps 1621,1622, by the mutual fastening of these left and right two cramps 1621,1622, and can block air and enters in vest 10.The position of closed position this slide fastener 161 relative of left and right two cramps 1621,1622 of sealing sheet 162 is staggered like, make the slider of zipper fastener 1611 of slide fastener 161 can not lean the closed position of these left and right two cramps 1621,1622, and the thing that slider of zipper fastener 1611 backs down left and right two cramps 1621,1622 and gas leakage can not occur.
Refer to Fig. 3 and Fig. 5.This vest 10 is provided with a gas input port 17, this gas input port 17 can be connected with the gas output tube of gas output device (not shown on figure), oxygen-containing gas is sent in vest 10, and make the air pressure in vest 10 be greater than the air pressure of working environment.This gas output device can be an air compressor, or is dynamical type aerating device.The gas transfer pipeline 20 that the inner connection flat of this gas input port 17 is flat-shaped, this gas transfer pipeline 20 can by the four limbs position 12,13,14,15 of oxygen-containing gas guide fence clothing 10.Refer to Fig. 6.This gas transfer pipeline 20 is mutually bonded with both sides by upper and lower two panels plastic cement thin slice 21,22, and the flat pipeline formed.The flexible pipe 30 extended along gas throughput direction is equipped with in the gas transfer pipeline 20 of this flat, make upper and lower two plate sheets 21,22 of this gas transfer pipeline 20 by this flexible pipe 30 separately, and can not because vest is under the collection of folding state, and under the too high environment of temperature, humidity, there is the situation that upper and lower two plate sheets 21,22 bind mutually.So can ensure that this gas transfer pipeline 20 is unimpeded state, enable oxygen-containing gas be transported to the four limbs position 12,13,14,15 of vest 10 fast, and be full of the inner space of vest 10.
Refer to Fig. 7 and Fig. 8.This flexible pipe 30 is provided with the helical form otch 31 from top to bottom extended.After oxygen-containing gas enters flexible pipe 30, the pressure of gas can strut otch 31, makes gas be filled with this gas transfer pipeline 20 by this otch 30, and can not affect the transfer rate of gas.Can place four flexible pipes 30 in the gas transfer pipeline 20 of this flat, these four flexible pipes 30 extend to four limbs position 12,13,14,15 by the inner of this gas input port 17 respectively.
Staff at work can shift position, and hand and head also have action, and some actions can extrude the partial high pressure that gas causes moment.For the sense of discomfort avoiding high pressure to cause staff, this vest 10 is provided with pressure relief device 40(as shown in Figure 2 at head and back), to discharge the gas causing instantaneous pressure.This vest 10 is provided with pocket 18 to settle this pressure relief device 40.
Refer to Fig. 9 and Figure 10.This pressure relief device 40 comprises relief valve 41 and an air guiding base 42.This relief valve 41 comprises one first thin slice 411 and one second thin slice 412.This first thin slice 411 has a perforation 413, and this perforation 413 is touched with the pressure relief opening 181 of this vest 10.This second thin slice 412 covers on this first thin slice 411, and four ends of its four end and the first thin slice 411 are affixed, to close this pressure relief opening 181.The pressure relief opening 181 of this vest 10 is provided with a circle film 182, and this film 182 can prevent the gas leakage in vest 10, as shown in figure 11.When only there is instantaneous pressure in vest 10, the second thin slice 412 can be backed down, Exhaust Gas.This relief valve 41 is the feature of common technology, non-invention.This air guiding base 42 is a forward and backward flat-shaped box body with opening.This air guiding base 42 front opening is provided with at least four bodies of rod 421, is out of shape to prevent front opening.This air guiding base 42 can insert in the pocket 18 of this vest 10, and this relief valve 41 imports in this air guiding base 42.When air discharged by this relief valve 41, between this first thin slice 411 and second thin slice 412, the swollen phenomenon that rises can be produced, to discharge air smoothly.The inner space of this air guiding base 42 is enough to allow that this first thin slice 411 and the second thin slice 412 do and is vented swollen effect of rising.
This air guiding base 42 includes top board 422 and base plate 423.The rear end of this top board 422 is provided with four perforation 424 gas can derived.The gas of being discharged by relief valve 41 can be flow to the end face of this air guiding base 42 by these four perforation 424, avoid swollen the rise state of all Exhaust Gas to the first thin slice 411 and the second thin slice 412 to have an impact.This base plate 423 trailing edge is provided with a recess 425.Namely the pressure relief opening 181 of this vest 10 is positioned at this recess 425.
After staff wears appropriate vest 10, must ensure that vest 10 is without holes or crack.If when vest 10 is because having holes or crack and causing gas leak phenomenon, life security or the health of staff can be jeopardized.Refer to Fig. 5.Vest 10 of the present invention is provided with the cock body 191 that a detect aperture 19 and can close this detect aperture 19.Be connected with the belt body 192 of a deflection between this cock body 191 with the outer wall of this detect aperture 19, cock body 191 and vest 10 are linked into an integrated entity.Before staff will enter workplace, first open cock body 191, insert pressure tester (not shown on figure), to detect the pressure in vest 10 by detect aperture 19.When pressure tester institute measuring pressure is pressure constant state, namely represent that vest 10 is air tight.After completing testing, cover cock body 191 and close detect aperture 19.This vest 10 separately can arrange the sealing adhesive plaster 193 with tearable property, and sealing adhesive plaster 193 is coated on the outside of this detect aperture 19 and this cock body 191.Before sealing adhesive plaster 193 is not torn, outside air cannot enter in the space between sealing adhesive plaster 193 and vest 10.Then staff can select whether will detect vest 10 before entering workplace.Detect vest 10 if select, just tear sealing adhesive plaster 193, detect.Do not detect vest 10 if select, just need not tear sealing adhesive plaster 193.
The vapour-pressure type vest of aeration provided by the present invention, it utilizes the flexible pipe of the tool helical form otch be set in the gas transfer pipeline of flat, makes gas transfer pipeline keep unimpeded.The present invention is separately provided with detect aperture and the air guiding base being arranged on relief valve place.This detect aperture before staff enters workplace, can do safety inspection to vest.This air guiding base can ensure the normal operation of relief valve energy.
More than illustrate just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that appended description limits; many amendments, change or equivalence can be made, but all will fall within the scope of protection of the present invention.
