Description

The water collection interface unit of vacuum drainage system device
Technical field
The utility model relates to the drainage system technical field of negative pressure as transmission power, particularly a kind of water collection interface unit of vacuum drainage system device.
Background technology
The municipal drainage system comprises gravity drainage system and non-gravity drainage system, a kind of as in the non-gravity drainage system of low-pressure drainage system, it is compared with gravity drainage system, has its special advantages for the drainage problem that solves indoor source separated and collected, outdoor outlying district drainage problem and hilly ground.Low-pressure drainage system is realized the sewage with duct end mainly by the suction function in the pipe-line system, drives by the negative pressure in the pipeline, is transferred to the vacuum collecting pumping plant from collecting boundary element.Generally, in the drainage system of indoor and outdoor, often at first by action of gravity, in specific collecting container, collecting container often maintains atmospheric pressure state with the interior sewage collecting that discharges of building, and then by the specific boundary element of vacuum drainage, sewage in the collecting container is pumped into vacuum pipe system, finally be transferred to the vacuum collecting pumping plant, so realize the collection transmission and the discharging of sewage, the sewage in the sewage collecting container is drained.So, at the front end of low-pressure drainage system, in terminal collector unit, a boundary element need be set by gravity drainage, requirement can be achieved as follows three kinds of functions: 1) cut off and being connected of vacuum pipe, realize utilizing under the normal pressure gravity collection sewage; 2) collect sewage and reach a constant volume, open the connecting interface with vacuum pipe automatically, drain collected sewage in the collecting container; 3) behind the sewage of in draining collecting container, collecting, cut off being connected of collecting container and vacuum pipe automatically, continue to collect the sewage of discharging.This boundary element will be realized alternately reciprocally operation automatically continuously under these three kinds of situations.
Nucleus equipment that this special boundary element is a low-pressure drainage system and major technique barrier are the significant obstacle that the restriction low-pressure drainage system is applied at home.At present relevant with low-pressure drainage system boundary element key equipment research and development mainly come from developed countries such as Germany, the U.S., Sweden, Japan.
Sweden engineer S.A.Joel Liljendahl has designed a kind of brand-new vacuum interface valve in 20 middle of century, has solved problems such as leakage, obstruction, anti-soil with the form of diaphragm valve, has solved low-pressure drainage system key issue in application problem [i]This vacuum diaphragm valve is improved in 1970 by the Johnson Service Company of the U.S., has adopted the structure of spring reset first, becomes the valve monomeric form of using till today [ii]Except pneumatic execution, the Bland Calvin Burns of the U.S. has designed a kind of diaphragm valve that utilizes electronic execution, but it requires along with vacuum line laying respective cable equipment provides the electric power support [iii]After this pass through research, developed and satisfied water, airtight, anti-blocking diaphragm bushing material elastomeric material [iv]At the beginning of 21 century, the Roediger Vacuum GmbH. of Germany just develops distinct vacuum interface valve-type, and it mainly utilizes the banding of a circle elastomeric material of all sides in the valve body and decontrols connection and the sealing of controlling vacuum line [v, vi]In addition, the Japanese valve body structure form of also having researched and developed baffle-type realizes opening and closing of vacuum line.
The triggering control device of vacuum interface valve is the Primary Component of equal importance with valve body itself.The Johnson Service Company of the U.S. has proposed rising liquid level compressing sealing gas and has triggered the principle of control device Open valve [vii]The method whether the induction suction pipe that the method for closing of valve then proposes with Japanese Ebara Corporation begins to aspirate atmosphere is representative [viii]In the research of the preposition air way switch valve door of interface valve, Johnson Service Company and Burton Mechanical Contractors, Inc. successively proposed structure and two spacing piston valve of static pressure buffer, the latter has also introduced the device of avoiding moisture condensation to stop up negative-pressure pipeline [ix]After this U.S. Airvac, Inc. have proposed to avoid the gas circuit control device by the method for liquid-immersed obstruction with the cock body that floats [x]These measures have improved the stability and the application life of system greatly.U.S. Burton Mechanical Contractors, Inc. adopt electric actuator control vacuum interface valve, realize the accurate operation of valve opening and closing for the accuracy of time-delay control and flow-control with electronic component [xi]
And the research and development of the relevant key equipment of domestic present against vacuum water collection interface unit, the main form of structure that adopts diaphragm valve or stop valve, the valve body structure form is comparatively simple, control module is many based on motor switch control form, lack supporting complete pneumatic control system, the check of engineering practical application effect is also not enough, adopts the mode of electronic control, and it exists 1) the equipment construction cost is higher; 2) problem such as anticorrosion protection against the tide is bigger to the threat of system's operation stability; 3) defectives such as a little all needing the externally fed facility of respectively catchmenting.
