Analysis of installation position of exhaust valve and gas storage position of pipeline

The following three precision valve company provides the pipeline gas storage location (1) where the pipe diameter changes In engineering construction, when the pipe diameter changes from large to small, the center line butt joint mode is generally adopted When the water flow speed is not large, the gas will gather at the junction and cannot be taken away by the water flow, forming an air bag (2) Top of pipe slope For sloping pipelines, the gas is generally upward in the water, which is easy to gather at the top of the slope, sometimes even blocking the pipeline and interrupting the flow (3) Pipe crossing At the intersection of pipelines, the flow of water generally flows from the large diameter to the small diameter, which is prone to gas accumulation at the place where the diameter changes (4) Adverse slope pipeline When the buoyancy is not enough to overcome the flow thrust, the gas will gather on the pipe wall and form the air bag (5) Inside and installation of various valves The installation position of the exhaust valve directly affects the exhaust effect and the running state of the pipeline In the design, designers are often limited to the local Zui high point In fact, there are many installation positions of exhaust valve Only when the whole pipeline is considered comprehensively, can the exhaust effect reach Zui best Common installation locations include the following: local Zui high point, the point where the descending slope becomes larger, the point where the ascending slope becomes smaller, and the long-distance pipe section where there is no break point for ascending or descending In addition, an exhaust valve shall be installed every 500-1000m
