Abstract
The utility model discloses a subdue pulsatory damping of pipeline fluid and fall device of making an uproar, intubate, outlet(discharge) flange dish in inlet flange dish, procapsid, leading interior intubate, reposition of redundant personnel awl, spring board, components of a whole that can function independently flange, back casing, rectification orifice plate, postposition. Advance, export to send out blue and outside pipe connection, the casing adopts removable integrated configuration so that inside the maintenance, the intubate adopts the design of 12 or 14 wavelength and opens and put the micropore in preceding, rearmounted to restrain duct noise and reduce the flow resistance, the reposition of redundant personnel awl is supported by the spring board, and the effect is water conservancy diversion and reduction flow resistance, the postpone of rectification orifice plate to but the rectification, fall and hinder and shake. During operation, fluid coil through inlet flange and get into, and the intubate is shunted with shunting the awl in leading, again through the rectification of rectification orifice plate, after intubate and the discharge of outlet(discharge) flange dish in rearmounted. The utility model provides a multi -functional pipeline pulsation mode of subduing, both can reduce the pulsation of pipeline fluid, can reduce duct noise and vibration again, operation safe and reliable.
Description
Technical field
This utility model relates to a kind of vibration and noise reducing device cutting down pipeline fluid pulsation, it is adaptable to the fields such as machinery, labor protection and environmental project, mainly solves the vibration and noise problem that pipeline fluid pulsation produces.
Background technology
Fluid machinery is widely used, and such as air compressor machine, water pump, blower fan etc., produces modern humans and has played great function in life, but pipe vibration and noise problem can be to environmental danger.Pipe vibration is a lot of with the inducement of noise, and fluid pulsation is one of principal element.Although though existing like product can reduce fluid vein momentum and noise at present, but overall dimensions is relatively big and takes up room more, has the new device that a kind of compact conformation to be developed, noise reduction frequency band are wider.
Summary of the invention
This utility model mainly solves the vibration and noise problem that pipeline fluid pulsation produces, it is provided that a kind of multi-method cuts down the vibration and noise reducing device of pipeline fluid pulsation in combination.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of vibration and noise reducing device cutting down pipeline fluid pulsation, it is characterized in that including suction flange dish, procapsid, preposition interpolation pipe, spreader, latch plate, split flange, back casing, rectification orifice plate, rearmounted interpolation pipe, outlet(discharge) flange dish, described outlet(discharge) flange dish and suction flange dish are by pipeline mounted externally for device, described spreader is supported by latch plate and is placed in preposition interpolation pipe end, and described rectification orifice plate is arranged in back casing.
Described latch plate number is 4～8, is uniformly distributed and is welded in procapsid.
Described spreader is by being welded to connect on latch plate.
Described rectification orifice plate is arranged in distance outlet more nearby, is bolted in back casing.
Described preposition interpolation pipe and rearmounted interpolation pipe length, by 1/4 or 1/2 design of noise wavelength, are connected with housing by welding with the form of interpolation.
Two described split flanges and front and rear housings, by being welded to connect, accompany rubber gasket, are bolted between split flange between two split flanges.
Described forward and backward shell length is proportional to the wavelength of flow noise.
This utility model is that pipe vibration-damping noise reduction provides a kind of new device, fluid, by spreader and latch plate parallel vein momentum, obtains rectification and secondary balancing, due to the change of pipeline impedance after rectification orifice plate, fluid dominant frequency noise is suppressed, thus pipe vibration reduces with noise.
Accompanying drawing explanation
Fig. 1 is this utility model embodiment entirety cross-sectional schematic.
Detailed description of the invention
A kind of vibration and noise reducing device cutting down pipeline fluid pulsation in Fig. 1, it is characterized in that including suction flange dish 1, procapsid 2, preposition interpolation pipe 8, spreader 6, latch plate 3, split flange 10, back casing 4, rectification orifice plate 7, rearmounted interpolation pipe 9, outlet(discharge) flange dish 5, described outlet(discharge) flange dish 5 and suction flange dish 1 are by pipeline mounted externally for device, described spreader 6 is supported by latch plate 3 and is placed in preposition interpolation pipe 8 end, and described rectification orifice plate 7 is arranged in back casing 4.Described latch plate 3 number is 4～8, is uniformly distributed and is welded in procapsid 2.Described spreader 6 is by being welded to connect on latch plate 3.Described rectification orifice plate 7 is arranged in distance outlet more nearby, is bolted in back casing 4.Described preposition interpolation pipe 8 and rearmounted interpolation pipe 9 length, by 1/4 or 1/2 design of noise wavelength, are connected with housing by welding with the form of interpolation.Two described split flanges 10 and front and rear housings, by being welded to connect, accompany rubber gasket, are bolted between split flange 10 between two split flanges 10.Described forward and backward housing 2 and 4 length is proportional to the wavelength of flow noise.
Specific implementation process: fluid is entered this device by preposition interpolation pipe, spreader and latch plate balance pressure fluctuation and by divided fluid stream, obtain rectification and secondary balancing, due to the change of pipeline impedance after rectification orifice plate, fluid dominant frequency noise is suppressed, thus pipe vibration reduces with noise.
The above is only preferred implementation of the present utility model, and in the range of this utility model limited without departing from claims, the change that this utility model is made by form details belongs to protection domain of the present utility model.
