Detailed description of the invention
The particular content of the present invention is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, pressure regulator with silencing apparatus, including: suction flange housing 1 and outlet(discharge) flange housing 2, in described suction flange housing 1, inlet channel 3 is set, it is provided with outlet passageway 4 in described outlet(discharge) flange housing 2, it is provided with valve seat 5 in described outlet(discharge) flange housing 2, interface channel 6 and locating piece 7 it is provided with in described valve seat 5, described locating piece 7 is fixedly installed valve port pad 9 by the first screw 8, the valve circle 10 cooperated with valve port pad 9 and valve circle back-moving spring 11 it is provided with in described inlet channel 3, it is provided with sealing ring 12 between described valve circle 10 and the inwall of inlet channel 3, the one end cooperated at described valve circle 10 and valve port pad 8 is internally provided with noise reducing damping block 13 and porous web plate 14, secondary noise reduction porous sheet frame 15 it is disposed with in the inside of described outlet passageway 4, a number porous web plate 16 and No. two porous web plates 17, it is filled with spring 18 in described secondary noise reduction porous sheet frame 15, described secondary noise reduction porous sheet frame 15, a number porous web plate 16 and No. two porous web plates 17 are fixedly installed on the fixed mount 21 in outlet passageway 4 by installing axle 19 and nut 20, described suction flange housing 1 is connected with upper membranous disc 23 by the second screw 22, described outlet(discharge) flange housing 2 is connected with lower membranous disc 25 by the 3rd screw 24, it is connected by connecting bolt 26 and attaching nut 27 between described upper membranous disc 23 with lower membranous disc 25, it is provided with air inlet oral cavity 28 between described upper membranous disc 23 and lower membranous disc 25, give vent to anger oral cavity 29, upper platen 30 and pressing disc 31, it is connected with each other by the 4th screw 32 between described upper platen 30 and pressing disc 31, homophony epithelium 33 it is provided with between platen 30 and pressing disc 31 on described, upper platen 30 is connected with described valve circle 10 with pressing disc 31, described upper membranous disc 23 is provided with the gas outlet joint 34 being connected with oral cavity 28 of giving vent to anger, described lower membranous disc 25 is provided with the air inlet connections 35 being connected with air inlet oral cavity 29, it is provided with sealing ring 36 between described valve circle 10 and described lower membranous disc 25.
When above-mentioned pressure regulator with silencing apparatus uses with pilot valve with the use of, by pilot valve control, the setting of pressure is determined by pilot valve, and therefore pressure regulator pressure adjusting function does not change.As shown in Figure 1, gas medium arrives the inner chamber of valve circle 10 by the inlet channel 3 in suction flange housing 1, producing under pressure-driven at pilot valve, homophony epithelium 33 produces side-to-side movement, is separated with valve port pad 9 by valve circle 10, connected by interface channel 6 between inlet channel 3 and outlet passageway 4, passage is opened, and gas medium flows, and medium is by the noise reducing damping block 13 in valve circle 10, air-flow is resolved into several small-bore passages, flows out valve seat 5. Medium enters secondary noise reduction porous sheet frame 15, and the spring 18 in secondary noise reduction porous sheet frame 15 makes the concussion that air-flow produces in this upstream, by spring 18 damping vibration, is substantially reduced gas flowing kinetic energy. Medium flows out secondary noise reduction porous sheet frame 15, through a porous web plate 16 and No. two porous web plates 17, under a porous web plate 16 and the double acting of No. two porous web plates 17, sudden change pressure drop is separated into repeatedly little gradual change pressure reduction, completes the process of two grades of noise reductions.
The operation principle of noise reducing damping block: be reduction noise from sound generating mechanism, gas is from the outside spray of acoustic filter in valve circle, jet noise crest frequency and nozzle diameter are inversely proportional to, and namely the noise energy of spout radiation will shift to high frequency along with diminishing of nozzle diameter from low frequency. If aperture is little to a certain extent, the frequency range that jet noise is insensitive by moving on to human ear.
Two grades of denoising device operation principles: according to reducing pressure by regulating flow principle, when gases at high pressure pass through the restricting orifice with certain circulation area, pressure is reduced. Connected by multi-level throttle orifice plate, it is possible to once big sudden change pressure drop when being originally exhausted directly to downstream is separated into repeatedly little gradual change pressure drop. Noise power is directly proportional to the high power of pressure drop, therefore pressure jump is changed into pressure gradual change, just can obtain soundproof effect.
The above-mentioned pressure regulator with silencing apparatus, take in the valve circle of pressure regulator, set a noise reducing damping block, reduce fluid dynamic energy, alleviate the impact to valve seat and valve seat pad, medium is by after valve seat simultaneously, secondary noise reduction is carried out, it is ensured that pressure regulator outlet noise reaches minimum then through two grades of denoising devices of pressure regulator.
