Description
Technical field
The utility model relates to the vacuum drain valves and toilet defecate collection of bleed valve field more particularly to a kind of unilateral row pressure
System.
Background technique
Bleed valve is one of the important composition components of the toilets such as train feces collecting system.As control of sewage disposal passage switching
Core, the quality of bleed valve quality and performance is directly related to train toilet system blowdown stability and entire train space
Spatter property.After dirt-collecting, scattered overflow of stink can pollute use space, this is an important drawback of dirt-collecting.Row
The application of valve is let out then while realizing that dirt discharges in time, stink has been effectively relieved and has dissipated excessive problem.It leads at present to be applied
Bleed valve form has: plate valve, moushroom valve and vacuum drain valve.Plate valve, moushroom valve are all that the opening and closing for realizing valve is pushed using cylinder, valve
Plate is easy to wear, and dirt easy to form gathers, and cleaning is difficult, and spoilage is very high.And vacuum drain valve rapid, damage with its opening and closing
The low advantage of rate is using more and more extensive.
China Patent Publication No. CN101349070, provides a kind of vacuum drain valve, and CN202274134U provides a kind of defecate collection
The excretion valve gear of device system application, the two propose two kinds of common bleed valve forms.Its major technique type is for valve body
One biggish cylindrical structure, inside superscribes, pressing member and guide rod by the variation of vacuum degree in valve body keep upper and lower casting die same
Shi Zuoyong squeezes rubber spacing body, the unlatching of control valve.The excretion valve arrangement is complex, and included part is more, structure is complicated,
It is high to be opened manufacturing expense, and it is big to damage maintenance difficulty；Simultaneously because body cavity is larger, the time required to vacuum degree variation relatively

Device is connected；Vacuum holes are connected by air valve with vacuum source, and the control closed by control module solenoid valve 12 is acted.
As shown in fig. 7, vacuum drain valve 1 is in close state, bath valve module 15, vacuum source and air valve etc. are not all opened
It opens, body cavity air pressure identical as the inner cavity air pressure of vacuum spacing body is all atmospheric pressure, and compression bar is pushed by spring force, makes vacuum spacing body
It is compressed, inner wall tightly fits together, and two first protrusion of compression bar lower part and the second male cooperation of body base are formed dual close
Envelope, it is ensured that vacuum spacing body is closed good, and gas leakage drainage does not occur.
As shown in figure 8,1 open state of vacuum drain valve, flushing switch 14 is pressed at this time, and bath valve module 15 works,
Vacuum source starting, air valve are opened, and body cavity air is pumped by vacuum holes, and air pressure decline forms certain vacuum degree,
The inside and outside certain pressure that formed of vacuum spacing body chamber is poor at this time, and the compression bullet of spring is overcome in conjunction with vacuum spacing body screen resilience itself
Power springs back vacuum spacing body, and inner cavity is opened, to be connected to dirt inlet and sewage draining exit.At this point, the vacuum due to blow-off line is made
With dirt is pumped by vacuum drain valve 1 in urinal 11, realizes the discharge of dirt.
Flushing period terminates, and vacuum source is closed, and body cavity is communicated with the atmosphere again, and it is atmospheric pressure that air pressure, which is gone up rapidly,
Vacuum spacing body chamber internal and external pressure balance, due to generating rebound by compression, compression bar pushes, makes in vacuum spacing body chamber again spring
Wall is bonded by compression, and vacuum drain valve 1 is closed.
The foregoing is merely preferred embodiment of the present application, are not intended to limit this application, for the skill of this field
For art personnel, various changes and changes are possible in this application.Within the spirit and principles of this application, made any to repair
Change, equivalent replacement, improvement etc., should be included within the scope of protection of this application.
