[embodiment]
To the embodiment of heating power aerosol sprayer carburetor breather cheek valve of the present invention shown in Figure 15, heating power aerosol sprayer carburetor breather cheek valve comprises housing 6, one-way valve diaphragm 8 and membrane baffle 9, baffler lid 2, central authorities sound absorption sponge 3, sidewall sound absorption sponge 4, acoustical panel 5, seal ring 7, wing screw 10 and central screw 1 at Fig. 2.Central screw 1 is installed in baffler lid 2 and central authorities sound absorption sponge 3 on the housing 6.The sidewall 601 usefulness dividing plates 602 of housing 6 tubulars are divided into 4 branch anechoic chambers 603, each branch anechoic chamber 603 and separating with acoustical panel 5 between the main anechoic chamber 604 of housing 6 central authorities has many noise reduction apertures 501 to be communicated with branchs anechoic chambers 603 and main anechoic chambers 604 on the acoustical panel 5.Sidewall sound absorption sponge 4 is housed in each branch anechoic chamber 603, and the central authorities of main anechoic chamber 604 are equipped with the central authorities sound absorption sponge 3 of column.The central authorities in the outside of the base plate 605 of housing 6 are unidirectional valve seat, and the one-way valve pore 606 that has 2 rows to be circular layout on the unidirectional valve seat, one-way valve pore 606 face the air flue between central authorities sound absorption sponge 3 and the acoustical panel 5.Have 2 to arrange the noise reduction aperture 201 that is circular layout on the baffler lid 2, the noise reduction aperture 201 of baffler lid 2 communicates with branch anechoic chamber 603.
Have the airflow clearance Δ between the resistance when reducing air inlet, sidewall sound absorption sponge 4 and acoustical panel 5, there are airflow clearance δ in sidewall sound absorption sponge 4 and baffler between covering 2.The mean value of airflow clearance Δ is 0.5 to 1.5 millimeter between sidewall sound absorption sponge 4 and the acoustical panel 5, and the mean value of airflow clearance δ is 0.5 to 1.5 millimeter between sidewall sound absorption sponge 4 and the baffler lid 2.
Acoustical panel 5 is the acoustical panel 5 of arc.For the fixing acoustical panel 5 of arc securely, and improve the sealing of connecting part, acoustical panel edge, there is erection column 502 at the two ends of arc acoustical panel 5, and there is the longitudinal socket 607 of arc acoustical panel erection column 502 dividing plate 602 outer ends, branch anechoic chamber.The arcuate furrow 608 that arc acoustical panel 5 is installed is arranged on the base plate 605 of housing 6.On the baffler lid 2 arcuate furrow 202 that arc acoustical panel 5 is installed is arranged.
For the ease of fixing of installation and baffler lid 2, dividing plate 602 covers the outstanding protuberance 609 of 2 directions at the oriented baffler in longitudinal socket position, baffler lid 2 pods 203 that have corresponding to protuberance 609.2 erection columns 502 short 1 long 1 of every arc acoustical panel 5 are short, and baffler lid 2 has 204,4 locating studs of 4 outstanding locating studs 204 to insert in the longitudinal socket 607 at short erection column 502 places.
There is the assembly department 610 of tubular in the outside of housing base plate, tubular assembly department 610 circumferentially uniform Carburetor bayonet socket 611 of 3 edges arranged in interior week.As Figure 13 and shown in Figure 14, there have 3 projections 1102 to insert in the bayonet socket 611 on the installation bead 1101 of Carburetor 11 to be fixing after the rotation.
In order further to improve erasure effect, the air outlet hole 615 of branch anechoic chamber is arranged on the base plate 605 of housing.At air outlet hole 615 positions, there is not airflow clearance between the base plate 605 of sidewall sound absorption sponge 4 and housing, the gas of discharging from air outlet hole 615 must pass sidewall sound absorption sponge 4, realizes auxiliary noise reduction.Between the installation bead 1101 of Carburetor 11 and the assembly department 610 of housing tubular noise reduction gap M is arranged, the air-flow that the branch anechoic chamber discharges from air outlet hole 615 enters atmosphere after the M noise reduction of noise reduction gap.
In order to guarantee the sealing between Carburetor and the breather cheek valve, between the installation bead of Carburetor 11 and the housing base plate 605 rubber seal 7 is housed.Seal ring 7 has 3 on the lug 701 mounting hole to be arranged along the uniform lug 701 of its periphery, and there are 3 seal rings, 7 mount pins 612 in the outside of housing base plate 605, and 3 lugs 701 of seal ring 7 hang on the mount pin 612 by mounting hole.Seal ring 7 respectively has the prominent lip 702 of 1 circle in housing 6 directions and Carburetor direction, and seal ring 7 has 1 circle groove 703 in housing 6 one sides, and groove 703 is positioned at housing 6 one sides, within the prominent lip periphery.The structure of 7 pairs of prominent lips of seal ring and groove can improve the elasticity of seal ring effectively, improves the sealing between Carburetor and the breather cheek valve.
One-way valve diaphragm 8 and membrane baffle 9 usefulness wing screws 10 are installed on the unidirectional valve seat in base plate 605 outsides of housing, the center convex 901 of membrane baffle 9 is pressed in one-way valve diaphragm 8 on the diaphragm attachment face 613 of unidirectional valve seat, the pore 902 of exerting pressure that the peripheral position of membrane baffle 9 has 2 rows to be circular layout, pulsating pressure acts on the outer surface of one-way valve diaphragm 8 by the pore 902 of exerting pressure, and makes closed check valve.The annular sealing surface 614 of unidirectional valve seat hangs down 0.15 to 0.25 millimeter than the diaphragm attachment face 613 of unidirectional valve seat.Like this, one-way valve diaphragm 8 has 0.15 to 0.25 mm clearance with the annular sealing surface of unidirectional valve seat under free state, can prevent between the annular sealing surface 614 of one-way valve diaphragm 8 and unidirectional valve seat viscous to take place, guarantee that one-way valve can respond fast to the high-speed pulse air pressure of motor.
Central authorities sound absorption sponge 3, sidewall sound absorption sponge in the present embodiment all are the nanosponges that melamine-formaldehyde condensation products is made.Because the nanosponges that melamine-formaldehyde condensation products is made has than high flame retardant, sound absorption properties and thermal insulation, can further improve the erasure effect of present embodiment.
Present embodiment adopts nanosponges as sound absorbing material, aperture noise reduction and the auxiliary noise reduction of air outlet hole 615 shuntings by the 604 resistive noise reductions of main anechoic chamber, acoustical panel 5 aperture noise reductions, the 603 resistive noise reductions of branch anechoic chamber, baffler lid 2 can reduce the noise that the heating power smoke machines produces greatly, reduce more than the 10dB than traditional heating power smoke machines noise, can improve operator's operating conditions effectively, reduce the influence of heating power smoke machines when work environment.
The gas-entered passageway of this enforcement Carburetor is unimpeded, and the sponge that do not absorb sound on the air flue stops that intake resistance is less, the engine efficiency height.
It is an assembly that present embodiment adopts the Carburetor breather cheek valve, and adopts snap fit to install with Carburetor, is convenient to dismounting and maintenance.
