Abstract
A one-way automatic air inlet valve comprises a valve body and a valve cap. The valve cap is arranged at one end of the valve body, a sealing cavity is formed between the valve cap and the valve body, and the other end of the valve body is an air outlet for being connected with a pipe. The valve body is provided with an air inlet channel communicated with atmosphere in sealed mode, and an air inlet of the valve is arranged at one end of the sealing cavity and connected with the air inlet channel. The air inlet is provided with a floatable seal assembly which 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 though a channel in the valve body. In the prior art, an existing air inlet valve has a technical problem that air inlet sensibility and air inlet speed of the existing air inlet valve can not be guaranteed simultaneously due to quality of a steel ball. The one-way automatic air inlet valve is not only capable of guaranteeing the air inlet speed, but also has better air inlet sensibility.
