(5) embodiment
As shown in Figure 1, a kind of combination vacuum generator, include the first housing, be located at the vacuum generating device in the first housing, described vacuum generating device includes nozzle 19, the expanding duct 18 that is positioned on the same axis, be provided with intakeport P between described nozzle, the expanding duct, the corresponding intakeport of the described first housing is provided with pipe joint 21, the corresponding expanding duct of the described first housing outside is provided with silencing apparatus 17, described nozzle 19, expanding duct 18 are the reconstruct part, and described nozzle, expanding duct are removably mounted in the described first housing; Described combination vacuum generator also includes the modulating valve of the adjusting suction pressure that is positioned at the second housing; Described modulating valve includes the air-inlet cavity C, the inner chamber G that are communicated with outer source of the gas, the exhaust cavity M that is communicated with the intakeport of the first housing, and the spool 11 of air-flow conducting is installed in the inner chamber movably between control air-inlet cavity, the inner chamber, and described exhaust cavity is communicated with inner chamber; A Sealing 4 that is connected on the spool is positioned at air-inlet cavity, and the air-inlet cavity chamber wall that described Sealing is inboard and corresponding forms throttle D, and the described Sealing outside withstands on the elastic component 12, and described elastic component is connected on the supporting sleeve 13; The described spool the other end withstands on the elastic sealing film 8 that constitutes inner chamber chamber wall, and the described sealing film outside is provided with spring regulating device.Described spring regulating device includes: bottom 7, gland 5, and described gland one end is provided with spring 6, and there is bolt 1 on the other end top, and the described bolt that is connected left end cap 3 is provided with locking nut 2; The other end of described spring is connected on the bottom 7, and described bottom 7 is connected with described sealing film 8.Described spool 11 includes a rectangular valve rod and stepped Sealing 4, is respectively equipped with the mounting hole of slightly larger in diameter in described valve rod in described elastic component 12, supporting sleeve 13, the inner chamber, and valve rod 11 is movably located in the described mounting hole.The first housing and the second housing are combined in the common body.Described exhaust cavity is provided with pressure gauge 9.Has identical outside Conncetion cimension with a series of reconfigurable spare nozzles, reconfigurable spare expanding duct.Described body 20, left end cap 3, right end cap 16 adopt light alloy material.
As shown in Figure 2, air-inlet cavity comprises A, B, the C hole of conducting, and inner chamber comprises D, E, F, G, H, I, J, K, the L hole of conducting, and exhaust cavity comprises M, N, the O hole of conducting.Embodiment is: pressurized air enters air-inlet cavity C by the hole B of the pipe joint A place on the right end cap 16 by supporting sleeve 13, then via reducing pressure behind the restriction D between spool 11 and valve body, enter the nozzle 19 of vacuum generator by the heavy hole 0 of valve body hole M, left end cap 3, because under the differential pressure action, the P place produces supersonic airstream between nozzle 19 and expanding duct 18, simultaneously, this place produces the region of no pressure, air is sucked by vacuum port Q place through pipe joint 21, produce the effect of aspiration vacuum, mixed gas slows down through expanding duct 18, by discharging behind the baffler 17 noise reduction sounds.
Compressed air pressure before the nozzle 19 can cover 5 by regulating bolt 1 roof pressure, thus pressure spring 6, and top bottom 7 and sealing film 8 come the aperture size of the restriction D between regulating spool 11 and valve body to realize, and show its force value by pressure gauge 9.When the fluctuation of the compressed air pressure value before the nozzle 19, pressure regulator valve is regulated automatically by reponse system, makes it constant.As when the compressed air pressure before the nozzle 19 raises, the M chamber, the E cavity pressure raises, the pressure regulator valve G cavity pressure that is communicated with by the F hole also raises, thereby push away sealing film 8 left, bottom 7 pressure springs 6, by the diaphragm center hole K of spool shutoff, bottom center hole L opens, G chamber gas passes through K, the L hole, the J chamber, the I groove, H hole expulsion valve is external, pressure descends, simultaneously, E, D place pressure also descends, and spool 11 is moved to the left under the effect of elastic component 12 and spool both sides pressure reduction, thereby close the restriction D between small valve core 11 and valve body, reduce charge flow rate, nozzle 19 preceding compressed air pressures are lowered, thereby keep the compressed air pressure value stabilization before the nozzle 19; Otherwise, when the compressed air pressure before the nozzle 19 reduces, nozzle 19 preceding force value are stablized.Compressed air pressure value stabilization before the nozzle 19 just can guarantee the vacuum generator proper functioning.
The present invention has the modular combination vacuum generator of regulating with stable suction pressure function and is not limited only to the foregoing description, and identical with the foregoing description principle ought to be included in the present invention.
