Background technique
Fig. 1 is the structural representation of the utility model background technique, the sentinel valve right-to-left is disposed with little valve gap, elastomer diaphragm, big valve gap, big elastomer diaphragm, nylon6 chips, winding-up pipe, elastomer diaphragm is carried out and is covered on the escape orifice and exhaust port of big valve gap, be provided with spring between big valve gap and the big elastomer diaphragm, the inlet hole that the air jet pipe top is provided with can be connected with air jet pipe inner chamber and escape orifice, pulse gas enters between little valve gap and the elastomer diaphragm through the control air port, promotes big elastomer diaphragm and nylon6 chips air jet pipe is carried out the pulsed blowing.Though this sentinel valve can be realized the dust catch sleeve of sack cleaner is oppositely jetted, the reaction time of big elastomer diaphragm and nylon6 chips paired pulses is longer, thereby causes ash-removal effect undesirable, and the working life of big elastomer diaphragm is shorter.
Summary of the invention
In order to overcome the technical deficiency that sentinel valve winding-up dust removing effects is poor, working life is short of existing pocket type pulsed dust collector, the utility model provides a kind of duster pulse valve, this sentinel valve has not only improved the dust removing effects of pocket type pulsed dust collector, and the long service life of sentinel valve.
The technological scheme that its technical problem that solves the utility model adopts is: be provided with valve body, the axial location of valve body is processed with escape orifice, the right side of valve body is provided with pulse wind chamber and exhaust port, escape orifice and exhaust port are covered by the elastomer diaphragm in the pulse wind chamber, this pulse wind chamber is sealed by little valve gap, little valve gap is provided with the control air port that communicates with pulse wind chamber, the valve body left side is fixed with the winding-up pipe, the inner chamber of winding-up pipe is connected with the winding-up general mood chamber in valve body left side, the string axle is installed in the escape orifice, be with spring on the string axle, the left part of string axle is fixed with a string axle metal diaphragm, and string axle metal diaphragm is positioned at indoor and the port that can shutoff winding-up pipe of winding-up general mood.The string axle is a hollow structure, is positioned at the indoor string axle of winding-up general mood and is provided with vent, and this vent is connected with the hollow cavity of string axle.Be provided with inlet hole between the madial wall of the outer of string axle metal diaphragm and winding-up general mood chamber.Can also adopt sealed mode to be slidingly matched between the madial wall of the outer of string axle metal diaphragm and winding-up general mood chamber, on the string axle metal diaphragm between air jet pipe outer and the indoor sidewall of winding-up general mood, be provided with inlet hole.
The beneficial effects of the utility model are that the pulse response time of metal diaphragm is short, has improved the dust removing effects of pocket type pulsed dust collector, and the long service life of sentinel valve, and is simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of background technique of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Winding-up general mood chambers 1. among the figure, 2. inlet hole, 3. winding-up pipe, a 4. string axle metal matrix, 5. vent, 6. spring, 7. escape orifice, 8. exhaust port, 9. little valve gap, 10. elastomer diaphragm, 11. control air ports, 12. pulse wind chambeies, 13. string axles, 14. valve bodies.
Embodiment
In Fig. 2, the escape orifice 7 that connects about the position, medial axis of valve body 14 is processed with, the left end of valve body 14 is provided with winding-up general mood chamber 1, the outside of winding-up general mood chamber 1 is fixed with winding-up pipe 3, the inner chamber of winding-up pipe 3 is connected with the winding-up general mood chamber 1 in valve body 14 left sides, the right-hand member of valve body 14 is provided with pulse wind chamber 12, pulse wind chamber 12 is connected with winding-up general mood chamber 1 through escape orifice 7, be processed with the exhaust port 8 that is connected with pulse wind chamber 12 on the right-hand member sidewall of valve body 14, escape orifice 7 in the pulse wind chamber 12 and exhaust port 8 cover through soft elastomer diaphragm 10, the right-hand member of valve body 14 is by little valve gap 9 shutoff, little valve gap 9 is provided with the control air port 11 that is connected with pulse wind chamber 12, string axle 13 is installed in the escape orifice 7, be with spring 6 on the string axle 13, the left part of string axle 13 is fixed with a string axle metal diaphragm 4, and string axle metal diaphragm 4 is positioned at winding-up general mood chamber 1 and can the shutoff winding-up manages 3 port.String axle 13 is a hollow structure, the string axle 13 that is positioned at winding-up general mood chamber 1 is provided with vent 5, this vent 5 is connected with hollow cavity on the string axle 13, between the outer of string axle metal diaphragm 4 and the madial wall of the general mood chamber 1 of jetting certain clearance is arranged, and this gap is inlet hole 2.Can also adopt sealed mode to be slidingly matched between the madial wall of the outer of the utility model string axle metal diaphragm 4 and winding-up general mood chamber 1, on the string axle metal diaphragm 4 between air jet pipe 3 outer side walls and winding-up general mood chamber 1 madial wall, be provided with inlet hole 2.
When the utility model uses, when control air port 11 does not have pulse wind to enter, pulse wind chamber 12 place's atmospheric pressure states, clean wind in the bellows chamber enters winding-up general mood chamber 1 through inlet hole 2, and enter escape orifice 7 through the inner chamber of vent 5 and string axle 13, pressurized gas in the escape orifice 7 are pushed elastomer diaphragm 10 open, gas is discharged in exhaust port 8, simultaneously, pressurized gas in the gas bag promote string axle metal diaphragm 4 and move right in winding-up general mood chamber 1, and the process medi-spring 6 that slides to the right at string axle metal diaphragm 4 is compressed.At this moment, if in pulse wind chamber 12, spray pressurized gas by control air port 11, then elastomer diaphragm 10 is with the right-hand member shutoff of exhaust port 8 and escape orifice 7, pressurized gas in the winding-up general mood chamber 1 can't be discharged through escape orifice 7 and exhaust port 6, then in spring 6 and winding-up general mood chamber 1 under the highpressure effect, a string metal diaphragm 4 moves to the right output port of winding-up pipe 3 suddenly, and manages 3 inner chamber winding-up high pressure clean air to winding-up.
