Embodiment
Embodiment below in conjunction with description of drawings the utility model.
As shown in Figure 1, a kind of explosion-proof equipment that is used for oxyhydrogen generator, it comprises negative pressure device 1, pipeline 2 and joint 3; Said negative pressure device 1 comprises tympanites 11, displacement sensor 12, first valve 13 and first drag link mechanism 14; The bulging face of tympanites 11 is processed by elastic material, and on the bulging face of tympanites 11 displacement sensor 12 is installed, with the change of state (depression, smooth or protruding) that detects bulging face; Displacement sensor 12 connects driving first valve 13 through first drag link mechanism 14; The bulging body of tympanites 11 (i.e. the circumference of tympanites) is preferably the wire loop structure, and drum is preset with two through hole (being two-port) on one's body, and a pipeline 2 respectively is installed on the two through hole; First valve 13 is installed in the pipeline 2, is used to realize the control to pipeline 2 aeration status; Joint 3 is installed on the port of pipeline 2, is used for being connected with equipment such as oxyhydrogen generators.
In addition, the explosion-proof equipment of the utility model can be provided with the negative pressure device 1 that is connected by pipeline more than two, simultaneously, the electromagnetic induction valve can also be installed, with further raising explosion-proof effect on pipeline.
Embodiment as shown in Figure 2 is two negative pressure devices and the explosion-proof equipment that the electromagnetic induction valve is combined: concrete; Two tympanites 11 are connected through pipeline 2; In pipeline 2, be respectively arranged with two first valves 13 and one second valve 42; Be respectively arranged with displacement sensor 12 on the bulging face of two tympanites 11; Displacement sensor 12 drives on corresponding first valve, 13, the second valves 42 through corresponding first drag link mechanism 14 and connects electric and magnetic oscillation transmitters 41 through second drag link mechanism 43, and wherein second valve 42, second drag link mechanism 43 and electric and magnetic oscillation transmitter 41 are promptly formed electromagnetic induction valve 4.
As shown in Figure 3, the explosion-proof equipment of Fig. 2 embodiment is installed on the oxyhydrogen generator, be about to the port of giving vent to anger that one of them joint 3 is connected oxyhydrogen generators; Another joint 3 connects equipment such as flame gun, and behind the unlatching oxyhydrogen generator, vibration to a certain degree takes place equipment such as oxyhydrogen generator and flame gun; After electric and magnetic oscillation transmitter 41 detects above-mentioned vibration at this moment, open second valves 42 automatically through second drag link mechanism 43, simultaneously; Because gas is fast through two tympanites 11; Air-flow can produce certain negative pressure in tympanites 11 fast, thereby makes bulging face be smooth or recessed state, and the displacement sensor 12 on the drum face detects the change of state of bulging face at this moment; Drive two first valves 13 respectively and be in opened condition; Make that whole gas passage is unimpeded, the gas that penetrates from oxyhydrogen generator through behind two negative pressure devices 1 and the electromagnetic induction valve 4, carries out operations such as metal cutting successively through flame gun; If flame gun is closed in the end of job, electric and magnetic oscillation transmitter 41 detects vibration to be stopped, and orders about second valve 42 through second drag link mechanism 43 and closes; The block gas passage; Prevent generation blasts such as tempering, can also send corresponding instruction simultaneously, order about the total valve of oxyhydrogen generator to close; If electromagnetic induction valve 4 blocking-up is not thorough, when in gas backstreaming to the tympanites 11, make the face of drum bulge; Displacement sensor 12 detects the change of state of bulging face, order about first valve 13 and close automatically, with gas occluding the tympanites 11 in; In case sh or tempering, tympanites 11 possibly blasted, and the design of the volume of tympanites 11 is less; And the intensity of rousing face up and down is lower, and therefore blast can not work the mischief, and can not cause the blast of oxyhydrogen generator; Through the protection of two negative pressure devices, can further improve explosion-proof effect.
What should explain at last is; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
