Closed water test water seepage amount automatic measuring device

Abstract

The invention relates to a closed water test water seepage amount automatic measuring device, which comprises an operation table frame assembly and a water supplementing measuring device installed onthe operation table frame, and is characterized in that the operation table frame assembly comprises an operation table, a level bubble and frame legs which are horizontally arranged; two ends of theoperation table are connected with the frame legs through hinge joints, and the level bubble is installed on the operation table; the water supplementing measuring device comprises a measuring cylinder, a sliding valve device, a floating ball and a rigid rod. The sliding valve device comprises a sliding valve, a sliding valve switch and a locking bolt. A measuring cylinder water outlet is formed in the bottom of the measuring cylinder, the measuring cylinder water outlet is fixedly connected with a slide valve water inlet hole, and a slide valve water outlet hole is fixedly connected with a thin water pipe; the floating ball is fixed to the lower portion of the rigid rod, and the upper portion of the rigid rod is fixedly connected with the sliding valve switch. The problem of pipeline water seepage amount measurement in a municipal drainage pipeline closed water test can be solved.

Description

technical field [0001] The invention relates to an automatic water seepage measurement device for a closed water test, belonging to the technical field of water seepage testing. Background technique [0002] At present, in the closed water acceptance process of municipal drainage pipelines, manual marking is generally used to measure the water head, and manual pouring is used to measure the water replenishment amount of seepage in the pipeline. Due to the error of artificially observing the water head and the limitation of the frequency of manual water pouring, it is impossible to ensure that the water head in the wellbore is always constant, that is, it is impossible to replenish water under constant pressure, which will easily affect the accuracy and reliability of the closed water test results. sex. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide an automatic measurement device for wat...
