Connection.Water source in wash water supply source 710 is input in closestool by rinse water valve 700, and bleed valve 800 is by the source of sewage in closestool
Sewage in 1000 is discharged by plumbing drain 1010.
The present invention's should for the control device of vacuum sewage system and the specific of specific embodiment of vacuum sewage system
It is as described below with situation：
Control device in Fig. 3 for vacuum sewage system is not pressed in unactivated state, i.e. actuating mechanism 300,
Now the second closeouts 230 are supported on the ledge structure 211 being against in the second cavity 214 by elastic component 240, leading on inner sleeve
The second through hole on through hole and the first cavity is blocked by the second closeouts 230, so that the port 140 of first port 120 and the 3rd
Cut-off, i.e., vacuum loop is blocked.In addition, less one end of external diameter of the first closeouts 220 is located at second port 130, this
When, 130 are in connected state, and one air loop of formation in the state being opened, first port 120 and second port 130,
Outside air is handed over by the lower left side fluting of the first closeouts 220 with being connected the first port 120 of wash water valve and bleed valve
Mutually, the direction of arrow of figure three is air circulation direction.Whole internal structure and inner body are by elastic component 240, spring 400 and first
Spring outside closeouts keeps stable nature.
Control device in Fig. 6 for vacuum sewage system is active, i.e., actuating mechanism 300 is pressed by external force
State, lid 213 is connected with button 300 by rod member, and valve system 200 is extruded from lid 213 to the direction close to three ports,
All elastic part in housing is compressed, and the first closeouts 220 are full of second port, the lower-left side opening of the first closeouts 220
At the horizontal lower edge of the inwall of chamber 110, now, second port 130 is closed, first port 120 and second port 130 every
Open, enclosure interior environment is blocked with extraneous air.In addition, when valve system 200 towards after the direction movement close to port, second blocks
Part 230 is stuck in the top of inner sleeve 150, and elastic component 240 and spring 400 are compressed.Now the 3rd port 140 connection vacuum holding
900 are put, negative pressure is produced, the 3rd port 140, inner sleeve is passed sequentially through by the negative pressure of the vacuum plant 900 shown in arrow in Fig. 6
150th, via hole 151, the second through hole 250, first port 120, three-way connection 600, act on rinse water valve 700 and bleed valve
On 800, the unlatching of rinse water valve 700 and bleed valve 800 is realized, in this trigger process, what actuating mechanism 300 was applied is outer
The direction of power and the traffic direction of vacuum loop are conllinear, and the direction of power is identical with outgassing direction.
After external force stop apply after, whole system by spring reaction force it is gradually slow must return to unactivated state,
Turn again to Fig. 3 schematic operational views.
Shown in Fig. 7 and Fig. 8, the control device of the present embodiment can also be added on the press-side of actuating mechanism 300 one by
Button 500, is user-friendly, and when site setup is constructed, each pipeline is embedded in wallboard, control device is also embedded in wallboard
On, button is only reserved outside wallboard, and each port of control device connects corresponding pipeline as shown in Figure 10 and Figure 11.
During normal use, first port 120 can be kept by the way that actuating mechanism 300 is pressed into its bottom position always
With the conducting of the 3rd port 140, the lasting unlatching of rinse water valve 700 and bleed valve 800 is realized, and extends flushing period.Such as horse
Bucket obstruction is blocked, then actuating mechanism 300 can be kept for a period of time in bottom position, more forcibly to rinse closestool.
It is a kind of vacuum sewage system sketch disclosed in the present embodiment if Figure 10 is to Figure 11, and the company between each equipment
Mode is connect, it is for reference.
Of course, in other specific embodiments, the connection side between each equipment in vacuum sewage system of the invention
Formula can be adjusted according to actual needs, and here is omitted.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
