Description

Automatic exhaust valve structure

Technical Field

The utility model relates to an exhaust valve technical field specifically is an automatic exhaust valve structure.

Background

When the floating ball type automatic exhaust valve is used in a hot water heating system, suspended impurities in a pipeline and a heating sheet often cause the blocking failure of a floating ball in the valve and the automatic exhaust, so that the heating of a unit or the whole building is not hot, and the heating quality is influenced. The most used at present is an automatic exhaust valve, the structure of which blocks the exhaust port by using the buoyancy of water. When the highest point of the pipeline is filled with air, the buoyancy of the water is reduced or eliminated, the air release port is opened, the air is discharged from the air outlet under the action of pressurized water, and when the air is discharged, the buoyancy of the water acts on a simple mechanical device to block the air release port. Unlike the exhaust of the gas collecting tank, the automatic exhaust valve does not need manual operation.

However, when an air conditioner such as a screw machine or a module unit is initially debugged and operated, a large amount of gas exists in the pipe, when the air conditioner water is driven by the circulating water pump to circulate, the gas is released in a large amount and is collected to the highest point, the exhaust speed of the automatic exhaust valve cannot be kept up to the maximum at this time, the exhaust is not timely, and when a pipeline system is initially operated, the gas continuously generates automatic exhaust, closing and exhaust on the exhaust valve, and the damage speed of the exhaust valve is greatly increased.

Based on this, the utility model designs an automatic exhaust valve structure to solve above-mentioned problem.
