Abstract

The invention discloses a novel automatic ventilate valve, comprising a valve body and a valve cover sealed and connected together to form a valve chamber. The bottom of the valve body is arranged with an air inlet. The valve cover is arranged with a horizontal air outlet. The valve chamber contains a floating ball whose upper part has a sliding channel with a connecting rod. The end of the connecting rod is arranged with a clamper whose end face is arranged with a groove. The groove is mounted with a pad ring. The horizontal air outlet is arranged with a handle whose head is arranged with a clamper, via one spring to engage the connecting rod. The handle is hollow to obtain a through hole whose outlet is communicated with the outer space. The inlet of the through hole is compacted with the pad ring of connecting rod. The invention can realize automatic ventilation via the air content of tube.

Description

technical field [0001] The invention relates to an exhaust valve, in particular to a novel automatic exhaust valve. Background technique [0002] The liquid medium transportation pipelines in daily life use the principle of atmospheric pressure to realize the transmission. In order to ensure the smooth flow of the pipeline, it is necessary to maintain a certain pressure difference between the inlet and outlet of the pipeline. If there is gas in the pipeline, it will have a certain impact on the pressure difference between the inlet and outlet of the pipeline, resulting in loud noise in the pipeline, failure of normal transportation of liquid media, and pipeline blockage. In actual use, the gas in the pipeline must be removed from time to time. Currently, the most commonly used method is to directly install an exhaust valve on the pipeline. Existing exhaust valves are generally divided into two types, one is an automatic structure, which can only realize a single exhaust fun...
