Abstract

The invention relates to a one-way automatic air inlet valve which comprises a valve body and a valve cover, wherein the valve cover is arranged at one end of the valve body, and a sealing cavity is formed between the valve cover and the valve body; the other end of the valve body is provided with an air outlet, the air outlet is used for connecting with a pipeline, and the valve body is hermetically arranged in an air inlet channel communicated with the air; the valve body is provided with an air inlet at one end of the sealing cavity, the air inlet is connected with the air inlet channel, and the air inlet is provided with a floatable sealing assembly; and the sealing assembly comprises a floating pin, a seal ring for sealing the air inlet is arranged on the floating pin, and the sealing cavity is connected with the air outlet through the channel in the valve body. The air inlet valve in the prior art has the technical problem that air inlet sensitivity and air inlet speed can not be guaranteed simultaneously due to the quality of steel balls, and the one-way automatic air inlet valve not only can guarantee air inlet speed but also has better air inlet sensitivity.

Description

technical field [0001] The invention relates to an intake valve, in particular to a one-way automatic intake valve capable of rapid intake. Background technique [0002] The intake valve is a valve used in a water tank or a pipeline to fill the cavity with gas. For example, in a large water tank or water pipe, the internal air pressure decreases during drainage. In order to ensure normal drainage, it is necessary to supplement air through the intake valve. [0003] Chinese patent document CN201513613U discloses an automatic intake and exhaust valve. A conduction pipe is arranged on the water tank. The upper end of the conduction pipe communicates with a valve body. An air intake steel ball, an exhaust round hole is set on the inner wall of the valve, and the position of the exhaust round hole is higher than the connection between the conduction pipe and the valve body, and an exhaust steel ball is placed on the exhaust round hole, and the valve body Both the upper end and ...
