加藥泵底閥本身有一定的重量可以維持吸液管線伸直況且使吸液管線鉛直于化學藥桶。額外加藥泵也是一個逆止閥，維持化學藥液的正向流動。底閥還有助于改善泵的重復精密度和正常吸液。底閥內(nèi)有濾網(wǎng)可以避免固體顆粒被吸入吸液管線，小的固體顆粒吸入有可能會造成計量泵隔膜破損。底閥還涵蓋連署件，用來連署吸液管。加藥泵底閥應該鉛直安裝，況且維持底閥離去儲藥桶底部一定距離。對于大部分數(shù)靠自吸形式辦公的計量加藥泵底閥挑選是十分不可缺少的(圖\文www.www.monolithcanada.com/)。

Dosing pump valve itself has a certain weight can maintain the suction line straight and to the suction line perpendicular to the chemical medicine barrel. Additional dosing pump is also a check valve, maintaining a positive flow of chemical solution. At the end of valve also helps to improve the repeatability and normal pump suction. At the end of valve within the filter to prevent solid particles are inhaled suction pipe, a small solid particles inhaled and may cause damage diaphragm metering pumps. Foot valve also covers the petition, to petition the pipette. Dosing pump valve should be installed vertically, and at the end of the medicine storage barrel bottom go to maintain a certain distance. For most rely on self suction form office dosing metering pumps valve selection is essential.
