VACUUM VALVE CONTROLLER AND VACUUM VALVE UNIT
PROBLEM TO BE SOLVED: To provide a vacuum valve controller that has a simple structure comprising one diaphragm and may be housed compactly in a sewage gully.SOLUTION: A vacuum valve controller includes: a casing 22 having a first chamber 26 communicating with a water level detection pipe 14, a second chamber 27 communicating with a suction pipe 11, a third chamber 28 communicating with vacuum piping 103, and a fourth chamber 29 communicating with a piston chamber 12a of a vacuum valve 12 formed inside; a vacuum valve switching mechanism 55 for switching between vacuum and atmospheric pressure supplied for opening/closing the vacuum valve 12; and a diaphragm 25 capable of reciprocating motion integrally with a shaft 23. The fourth chamber 29 is communicated with/blocked from the third chamber 28 and an outside part of the casing 22, by the reciprocating motion of the shaft 23. The shaft 23 moves in a direction to open the vacuum valve 12 when a pressure difference arises between both sides of the diaphragm 25, by bringing air inside the fourth chamber 29 to negative pressure.SELECTED DRAWING: Figure 2
【課題】１つのダイヤフラムで構成される簡単な構造とすることができ、汚水ます内でコンパクトに収容することが可能となる。【解決手段】水位検知管１４に連通する第１室２６、吸込管１１に連通する第２室２７、真空管路１０３に連通する第３室２８、及び真空弁１２のピストン室１２ａに連通する第４室２９を内部に形成したケーシング２２と、真空弁１２の開閉動作のために供給する真空及び大気圧を切換える真空弁開閉機構５５と、シャフト２３と一体に往復動可能なダイヤフラム２５と、を備え、第４室２９は、シャフト２３の往復動作によって、第３室２８との間で、かつケーシング２２の外部との間で連通又は遮断され、シャフト２３はダイヤフラム２５の両側に差圧が生じたときに、第４室２９内の空気を負圧にして真空弁１２が開く方向に移動する真空弁制御装置を提供する。【選択図】図２
