Description
Technical field
This utility model belongs to vacuum drainage field, particularly relates to sewage collecting and the automatic-discharging well of a kind of gravity stream and vacuum-flow transition.
Background technology
Current outdoor drainage system mainly adopts gravity system, and user side sewage, by the gravity pipe line laid under road direction, is flowed to lower by eminence under terrestrial gravitation effect.It is simple that gravity drainage system has construction, the advantages such as operation expense is relatively low, but its shortcoming is also fairly obvious, namely being subject to landform restriction big, excavated volume is big, and ground failure is strong, substantial amounts of inspection shaft, elevator pump and inverted siphon need to be set, thus causing that construction is difficult, construction cost is high along road.
In recent years, utilizing vacuum collecting to process sanitary sewage and enter into the visual field of people gradually, vacuum pipe is laid and is not needed the gradient, applied widely, reduces cutting depth, saves construction space and capital construction cost.Its operation principle is: sensed the signal of liquid level sensor in well body by controller, thus the opening and closing of vacuum valve on control of sewage disposal pipe, it is achieved the suction of sewage.But in order to realize the action of controller noted above, in addition it is also necessary to increase extra power-equipment, such as compressed air source or power supply, this directly increases working strength when arranging pipeline.Particularly with the remote mountain areas of some poor infrastructures, usually construction can be affected less than electric power facility because finding.
In addition, in order to safeguard the safety of system, in addition it is also necessary to controller is made regular check on maintenance, owing to drainage system cannot work in Inspection and maintenance process, the orthobiosis of people can also be affected.
Utility model content
Given this, the purpose of this utility model is to provide in a kind of outdoor vacuum drainage system for gravity to flow to sewage collecting and the automatic-discharging well of vacuum-flow transition, when in well body, liquid level reaches predetermined altitude, the negative pressure in vacuum line is utilized to automatically turn on vacuum valve, making sewage automatically enter vacuum line, it is not necessary to increase extra power-equipment, the mountain area for electric power facility shortcoming is especially suitable, meanwhile also there is safety height, the advantage that kinetic equation loss is little.
This utility model solves its technical problem and be the technical scheme is that a kind of sewage collecting and automatic-discharging well, including the gravity feed pipeline being connected with user side, well body, the upwardly extending blow-off pipe in portion in well body, the vacuum valve being connected with blow-off pipe, and the vacuum line connected with vacuum valve.
Wherein, vacuum valve includes working chamber, the medium entrance docked mutually with blow-off pipe, the media outlet being connected with vacuum line, and communicate with working chamber, for controlling medium entrance and the pilot valve of media outlet break-make.Vacuum line is additionally provided with air hatch, above-mentioned pilot valve is provided with the vacuum interface docked mutually with this air hatch, and the air interface of atmosphere, and for sensing the pressure interface of well body inside liquid level.Also being equiped with the sensing element extending downward well body on pressure interface, this sensing element includes the air pressure transmission conduit being arranged on pressure interface, and is connected for sensing the induction tube of liquid level in well with this air pressure transmission conduit.
Adopting technique scheme, sewage flows by gravitational force into well body, and when the sewage in well body increases gradually, the liquid level in induction tube increases, and forces intraductal atmospheric pressure to raise, and intraductal atmospheric pressure is delivered to the pilot valve of vacuum valve by air pressure transmission conduit.When in tank, liquid level reaches predetermined altitude, pilot valve automatically switches to vacuum interface, is connected with vacuum line by vacuum valve.Work chamber air is sucked away, under the atmospheric pressure of medium inlet, and vacuum break valve.Owing to the air pressure of the blow-off pipe at vacuum valve two ends, vacuum line is different, valve is once unlatching, and sewage is just sucked at a high speed vacuum line.When the sewage in well body is sucked away in process, water level is gradually reduced, air pressure in induction tube also declines therewith, when dropping to predetermined fluid level, pilot valve switches to air interface, and vacuum valve disconnects with vacuum line simultaneously, and vacuum valve is closed, sewage stops discharge, so far completes one and collects discharge process.
As further improvement of the utility model, well body divides upper and lower two-layer, is made up of the sewage temporary storage tank of the vacuum valve chamber on upper strata and lower floor, and the tight sealing of levels better controls foul smell, and then improves surrounding enviroment.The sidewall of vacuum valve chamber has the interspersed mouth for disposing vacuum line, gravity feed pipeline is arranged on the sidewall of sewage temporary storage tank, it is additionally provided with sealing plate between described vacuum valve chamber and sewage temporary storage tank, the interspersed mouth of blow-off pipe and the interspersed mouth of induction tube is offered on this sealing plate, valve and sewage are completely cut off, it is simple to safeguard.
