Abstract

The invention discloses an automatic exhaust valve, comprising: a casing, the casing is a hollow structure with an open top, and a first convex column protruding upward is formed in the center of the bottom inner wall of the casing, and an opening is formed on the first convex column The upward first guide groove is also provided with a water inlet hole on the bottom wall of the casing; the cover body is adapted to be installed on the top of the casing, and a second convex column extending downward is formed in the center of the inner wall of the top of the cover body. A second guide groove with a downward opening is formed on the second convex column, and the second guide groove is arranged opposite to the first guide groove; the side wall of the second convex column is also provided with an exhaust port that communicates with the outside and is connected to the shell The exhaust channel communicated with the inner cavity; the valve core, the bottom and the top of the valve core slide in the first guide groove and the second guide groove respectively, and a buoy is also fixed on the side wall of the valve core. The automatic exhaust valve is simple in structure, reasonable in design, convenient in installation, and has good sealing effect.

Description

technical field [0001] The present invention relates to the technical field of exhaust of pipes or water systems, and more particularly to an automatic exhaust valve. Background technique [0002] At present, the existing automatic exhaust valves are only suitable for low-pressure exhaust applications. When it reaches the valve body, due to the action of air pressure, the liquid level in the valve body moves down, and the float drops accordingly. When it falls to the lower limit, the lever system is linked to open the valve port of the exhaust valve to release the gas under pressure, and then the pressure in the valve decreases due to The liquid level moves up, the float rises, and under the action of the spring force, the exhaust port is closed. When this type of exhaust valve is under high system pressure, in order to make the exhaust port open in the normal exhaust state, the gravity of the float must increase a lot, so that the float can overcome the working pressure of...
