Fig. 1 is a schematic structural view of the present utility model.
Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings by means of specific examples.
As shown in fig. 1, the utility model provides an exhaust valve device capable of controlling the pressure of liquid in a pipeline, comprising an exhaust valve body 1, wherein an air inlet component 2 is arranged at the bottom of the exhaust valve body 1, an air outlet 3 is arranged at the side part above the exhaust valve body, a cavity 4 is arranged between the air inlet component 2 and the air outlet 3, a spring seal component 5 is arranged at the air outlet 3 in the cavity 4, a float 6 for driving the spring seal component 5 is arranged below the spring seal component 5 in the cavity 4, and the float 6 is connected with the spring seal component 5 through a lever 10 at the top.
The top of the exhaust valve body 1 is provided with an electric contact type pressure gauge 7.
