Illustrate first use process of the invention with reference to the accompanying drawing:
In the present embodiment, the height of water is set as 1.5 meters or so, and the length of power water pipe 9 is 8 times of the height of water, then
The length of power water pipe 9 takes 12 meters, while the inclination angle of power water pipe 9 is set as 8 °, and 19 end of operation water pipe is equipped with water mist spraying head,
Purpose is to generate high-pressure fog.
Firstly, the first shut-off valve 4, the second shut-off valve 13 and third shut-off valve 18 are all turned on, the water source at high water level
It will be flowed into the first tubular type pump chamber 1 along power water pipe 9 under the effect of gravity, due to the first noise reduction drain valve under original state
3 is in the open state, the water flow in the first tubular type pump chamber 1 by the permeable mouth 24 of cross for passing sequentially through the first noise reduction drain valve 3,
Outside 29 dump valve of permeable orifice plate 25 and drain hole, but within a very short time, the flow velocity of water is just up to high level, is penetrating at this time
Under stream effect, disc valve block 21 quickly moves up and blocks the permeable mouth 24 of cross, and the first noise reduction drain valve 3 is transformed into pass
Closed state.
Due to the unexpected closing of the first noise reduction drain valve 3, quick flowing water moment under effect of inertia generates one very
High pressure, this pressure will act on around, to generate water hammer effect.Under water hammer effect, in the first tubular type pump chamber 1
Water will quickly through the first high pressure water inlet pipe 6 and open the first check valve 7 enter first collection pressure buffer air tank 5 in, simultaneously
Also pressure release is completed in first tubular type pump chamber 1, and the first check valve 7 is also by quick closedown, pressure is mothballed to the first collection pressure buffering
In air tank 5, first order pressurization is completed.
After first order pressurization, pressure moment is reduced in the first tubular type pump chamber 1, the first noise reduction drain valve 3 at this time
Under the action of valve block reset drives spring 28,21 Rapid reset of disc valve block, the permeable mouth 24 of cross restarts to sluice,
Pressurization is not prepared next time.
For the high pressure water in the first collection pressure buffer air tank 5, the will be entered by 8 high speed of the first high pressure water delivery pipe
In two tubular type pump chambers 10, and the second noise reduction drain valve 12 is by the quick closedown under the water impact of high speed and high pressure, to produce again
Raw water hammer effect, under second of water hammer effect, the water in the second tubular type pump chamber 10 will be quickly through the second high pressure water inlet pipe
It 15 and opens second one-way valve 16 and enters in the second collection pressure buffer air tank 14, while completing pressure release in the second tubular type pump chamber 10,
And the also quick closedown of second one-way valve 16, pressure are stored in the second collection pressure buffer air tank 14, complete second level pressurization.
After the pressurization of the second level, the pressure moment in the second tubular type pump chamber 10 is reduced, and the second noise reduction at this time sluices
Valve 12 reopens under the action of valve block reset drives spring 28, and pressurization is not prepared next time.
For the high pressure water in the second collection pressure buffer air tank 14, very high pressure is being already had after two-step supercharging
Power, high pressure water at this time will be entered in operation water pipe 19 by the second high pressure water delivery pipe 17, eventually by 19 end of operation water pipe
High-pressure fog needed for the water mist spraying head at end generates operation.
In terms of noise reduction, drain valve of the invention uses completely new noise-reducing design, uses and " directly lets out with traditional drain valve
The sluicing mode of formula " is different.Due to the valve rod of traditional drain valve be by valve casing at the top of open guiding trestle it is directly fixed
, and drain hole then directly cooperates with valve block, and very big noise and vibration can be generated during sluicing.
The present invention has abandoned the sluicing mode of " directly letting out formula ", has installed cylinder barrel shaped additional at the top of cylinder barrel shaped valve casing 20 first
Sound proof housing 23, and permeable orifice plate 25 is additionally arranged inside cylinder barrel shaped sound proof housing 23, and permeable orifice plate 25 is simultaneously also as circle
The guide support frame of cylindricality valve rod 22 comes using first passing through permeable orifice plate 25 by the water that the permeable mouth 24 of cross is discharged and complete to hinder
Then reduction of speed completes buffering deflecting by 23 top plate of cylinder barrel shaped sound proof housing again, is finally discharged, is effectively reduced by drain hole 29
Noise when sluicing, while can also reduce vibration when sluicing, and reduce the injury vibrated to sluicing valve body.
The scope of patent protection that scheme in embodiment is not intended to limit the invention, it is all without departing from carried out by the present invention etc.
Effect implements or change, is both contained in the scope of the patents of this case.
