an exhaust device

Abstract

The invention relates to an exhausting device which comprises an exhausting valve, a filter net, a floater and a connecting rod. A gas-liquid inlet is formed in the bottom end of the exhausting valve, an exhausting port is formed in the top end of the exhausting valve, an exhausting valve element is arranged at the exhausting port of the exhausting valve, the filter net is arranged inside the exhausting valve and divides the same into two areas including an exhausting cavity close to the exhausting port and a gas collection cavity close to the gas-liquid separating inlet, the connecting rod and the floater are arranged in the exhausting cavity, the top end of the connecting rod is fixedly connected with the exhausting valve element, the connecting rod moves downwards to enable the exhausting valve element to be in an open state, and a bent portion used for placement of the floater is arranged at the bottom end of the connecting rod. The exhausting device can effectively avoid gas-water mixed discharging.

Description

technical field [0001] The invention belongs to the technical field of exhaust, and in particular relates to an exhaust device. Background technique [0002] At present, the exhaust valves commonly used in water circulation systems have the following defects: [0003] 1. The air collection and exhaust chamber is too small, especially the air collection chamber is very small, which is particularly prone to the phenomenon of mixed discharge of air and water; [0004] 2. Due to the small size of the gas-collecting cavity, the impurities in the water can easily pass through the gas-collecting cavity and cause blockage at the exhaust port, which affects the exhaust and is also prone to water leakage, which has caused great troubles for people in their lives. Serious leaks require uninterrupted replenishment of water, wasting resources and costing more. Contents of the invention [0005] In view of the problems existing in the prior art, the present invention provides an exhau...
