Lid 14 and lower cover 15 are all provided with through-hole.The through-hole of upper cover 14, the cross aisle of diaphragm 16, lower cover 15 through-hole form a row
Gas channel.Gas or granule foreign can pass sequentially through the through-hole of upper cover 14, the cross aisle of diaphragm 16, lower cover 15 it is logical
The opposite direction of hole or sequence described above.
When the diaphragm type that the high pressure gas of discharge encounters soft texture can substantially reduce the shriek of air-flow, if discharge
When containing granule foreign in high pressure gas, impurity can also easily pass through the cross exhaust passage on diaphragm.
Fig. 5 is equipped with rotatable feces collecting system schematic diagram in the train of muffler of the present invention.As shown in figure 5, feces collecting system packet
Include transferring box 1.The entrance of transferring box 1 is equipped with inlet valve 2, and the outlet of transferring box 1 is equipped with outlet valve 3.
It further include pneumatic board 5.Air passage block composition 6 is installed on pneumatic board 5.It is equipped with first on air passage block composition 6
Solenoid valve 7 and second solenoid valve 8.
First solenoid valve 7 is connected to inlet valve 2 by gas pipeline.Second solenoid valve 8 is connected to out by gas pipeline
Mouth valve 3.Fig. 6 is the scheme of installation of muffler of the present invention.As shown in fig. 6, muffler 13 is installed on the gas pipeline of inlet valve 2
Between the gas pipeline of outlet valve 3.
After second solenoid valve 8 must be electric, high pressure gas is sent into outlet valve 3, and outlet valve 3 is closed.When the first solenoid valve 7 obtains
When electric, high pressure gas is sent into inlet valve 2, and inlet valve 2 is closed.After the first solenoid valve 7 and 8 all dead electricity of second solenoid valve, enter
Mouth valve 2 and outlet valve 3 are opened, and the high pressure gas being sent into when carrying out shutoff operation before passes through the chamber stream of air passage block composition 6
Enter to the exhaust outlet of installation muffler 13.It is blocked if muffler 13 is unexpected, there is the risk for leading to the action failure of inlet valve 2, and originally
The application muffler 13 is then without blocking risk, so there is more preferably technique effect compared with the existing technology.
Specifically, the inlet valve 2 and outlet valve 3 of transferring box 1 are to realize to open by the air passage block composition 6 on pneumatic board 5
With the conversion of closing.When air passage block composition 6 on two at solenoid valve 7 and 8 respectively it is electric when, high pressure gas is delivered to entrance respectively
At valve 2 and outlet valve 3, they are closed respectively.
Button 4 is electrically connected with second solenoid valve 8, can start second solenoid valve 8.It further include vacuum generator composition 9
With water plate 10.Vacuum generator composition 9 is connect by gas pipeline with transferring box 1, can carry out vacuum pumping to transferring box 1
Or apply high pressure gas operation.Water plate 10 is connect by flushing pipeline with closet 11, and toilet flushing 11 is used for.Closet 11 goes out
Mouth is connect with the entrance of transferring box 1.The exit of closet 11 is equipped with bleed valve.The outlet of transferring box 1 is connected to dirt box 12.
The invention also discloses a kind of noise reduction methods of rotatable feces collecting system air passage block in train, specifically include following step
Suddenly：
Step 1, system are in original state, and the inlet valve 2 and outlet valve 3 of transferring box 1 are all opening state.
Step 2, after passenger's activator button 4, the second solenoid valve 8 on air passage block on pneumatic board 5 composition 6 must electrically activate
Action, high pressure gas is delivered at outlet valve 3, is turned off.9 activation of vacuum generator composition simultaneously, carries out transferring box 1
Vacuuming action, after the negative pressure value of transferring box 1 reaches default value, vacuum generator composition 9 is stopped.It is same with this
When, water plate 10 carries out water flushing using high pressure water to closet 11.The bleed valve of closet 11 is opened, in emissions to transferring box 1.
Step 3,8 dead electricity of solenoid valve, outlet valve 3 are opened.System is restored to standby mode.
Step 4, when dirt reaches a constant volume in transferring box 1, the first solenoid valve 7 and second solenoid valve 8 electric, high pressure
Gas is delivered to respectively at inlet valve 2 and outlet valve 3, and inlet valve 2 and outlet valve 3 are closed, while vacuum generator composition 9 swashs
It is living, transferring box 1 is carried out to apply high pressure gas action.After the time of setting, 8 dead electricity of second solenoid valve, outlet valve 3 is beaten
It opens, the dirt in transferring box 1 is emitted under the promotion of air pressure in dirt box 12.First solenoid valve 7 also dead electricity later, inlet valve
2 open.Close before the high pressure gas of inlet valve 2 and outlet valve 3 by air passage block form in chamber flow to installation muffler
13 exhaust ports reduce noise.System is restored to standby mode.
Particularly, the principle of the above workflow is that the bleed valve of closet 11 is closed in feces collecting system, transferring box 1
After outlet valve 3 is closed, transferring box 1 forms a closed space.After activating push button 4,9 activation of vacuum generator composition
Action, compressed air can take away the air in transferring box 1 by vacuum generator composition 9, form negative pressure.It is when negative pressure value reaches
After setting value of uniting, vacuum generator composition 9 is stopped, and at the same time high pressure water washing closet 11, the bleed valve of closet 11 are beaten
It opens, the dirt and water in bedpan are run along blow-off pipe to transferring box 1 under the promotion of external atmospheric pressure, when dirt and water running
Vacuum and ambient atmosphere is equally isolated in statuary column plug, and pressure difference will push dirt to advance always, until dirt enters transferring box 1.
The inlet valve 2 of subsequent transferring box 1 is closed, and vacuum generator composition 9 makes positive pressure, the outlet valve of subsequent transferring box 1 into transferring box 1
3 activation are opened will be in emissions to dirt box 12.
The inlet valve 2 and outlet valve 3 of transferring box 1 be by change air passage block form 6 solenoid working conditions realize into
The switch closed state of mouth valve 2 and outlet valve 3.Air passage block composition 6 can be by pipeline during realizing valve switch conversion at two
In high pressure gas discharged, during release high pressure gas by air passage block internal chamber to exhaust ports when can send out
More apparent shriek increases a muffler 13, to reduce noise in the exhaust ports of air passage block thus.
What has been described above is only a preferred embodiment of the present invention, and present invention is not limited to the above embodiments.It is appreciated that this
The other improvements and change that field technology personnel directly export or associate without departing from the spirit and concept in the present invention
Change, is considered as being included within protection scope of the present invention.
