Abstract

The invention relates to a combined air vent valve with a buffer device. The combined air vent valve comprises a valve body and a valve deck which is arranged on the upper portion of the valve body and connected with the valve body in a sealing mode. The combined air vent valve is characterized in that the valve body is in an inverted gourd shape and is divided into an upper air exhausting cavity and a lower buffer cavity; a floating ball air exhausting device is arranged in the upper air exhausting cavity, and a floating ball buffer device is arranged in the lower buffer cavity; and a water outlet communicating with the upper air exhausting cavity is formed in the side wall of the valve body, a water inlet is formed in the bottom of the lower buffer cavity, the valve deck is provided with an exhaust port, and the exhaust port is provided with an exhaust hood. Compared with the prior art, the combined air vent valve has the advantages of buffer sewage discharge, safety water hammer preventing, sewage ejection preventing and the like.

Description

technical field [0001] The invention relates to a sewage exhaust valve, in particular to a composite exhaust valve with a buffer device. Background technique [0002] In the sewage drainage pipeline, because there is a large amount of gas in the initial stage of water delivery and drainage during the water delivery process and a small amount of dissolved gas in the normal delivery water, it is necessary to use a sewage composite exhaust valve installed on the pipeline for massive exhaust and trace discharge. Gas, improve water delivery or drainage efficiency, but often in the process of massive exhaust and closing process of sewage composite exhaust valve, a large amount of sewage in the pipeline will be sprayed out instantaneously and the instantaneous water hammer in the closing process will easily damage the valve components and pipelines Attachments, the light ones will cause environmental pollution, and the severe ones will cause safety hazards. Contents of the invent...
