Description

Technical Field

[0001] The utility model relates to the technical field of exhaust valves, in particular to an exhaust valve with a special harmful substance detection structure. Background Art

[0002] Exhaust valves are used for exhaust in independent heating systems, central heating systems, heating boilers, central air conditioners, floor heating and solar heating systems. Exhaust valves are divided into heating type, trace type, fast type, compound type, etc.

[0003] In the existing exhaust valve structure, the valve core is a float, which is directly built into the exhaust channel, and the exhaust port is located above the float. When the pipeline is exhausted at a high speed (such as when the pipeline is first filled with liquid), the valve is easily blocked (that is, the float is blown up by the high-speed gas and blocks the exhaust port). As a result, the exhaust is not completely completed, forming an air bag embolism in the pipeline, thereby reducing the efficiency of liquid transportation in the pipeline.

[0004] Existing patent (publication number: CN212251409U) This utility model discloses a composite exhaust valve, including an exhaust valve cover, an exhaust valve body, a movable valve core, an exhaust valve sealing ring, a ball basket and a float; the exhaust valve cover is connected to the top of the exhaust valve body; the exhaust valve body is hollow, and the exhaust valve cover is provided with a first inlet and exhaust port; the exhaust valve sealing ring is fixedly connected to the bottom of the exhaust valve cover; the ball basket is fixed to the inside of the exhaust valve body; the air in the pipeline is discharged through the inside of the exhaust valve body → the upper through hole → the first inlet and exhaust port, which can meet the demand for rapid exhaust of the pipeline, and during the entire exhaust process, because the float is located in the ball basket, it is not easily blown up by the action of too fast airflow, thereby preventing the valve from being blocked and avoiding the reduction of water transportation efficiency in the pipeline due to incomplete exhaust.

In addition, existing exhaust valves usually lack exhaust gas purification and treatment structures, so that the exhaust gas will pollute the air environment after being discharged.

[0006] Therefore, an exhaust gas valve with a special harmful substance detection structure is proposed. Utility Model Content
