Abstract

The invention discloses a small quick exhaust valve, and aims to provide a small quick exhaust valve which is smooth in exhaust. The small quick exhaust valve comprises a valve body, and a valve element arranged in the valve body; the valve body comprises a shell with a cone-frustum-shaped cavity, and a valve deck; one end, with a larger area, of the shell is named as a lower end, and the other end opposite to the lower end is named as an upper end; a connecting pipe used for being connected with a pipeline is fixedly arranged at the lower end of the shell, and an internal thread section used for connection is arranged in the connecting pipe; the upper end of the shell is open, and an external thread section is arranged on the outer wall of the open end; the valve deck is in threaded connection with the upper end of the shell, and four exhaust pipes are annularly and uniformly distributed on the end surface of the valve deck; the valve element is frustum-shaped, and a certain gap is formed between the valve element and the inner wall of the lower end of the valve body; the valve element comprises a frustum-shaped body part, and additional parts annularly and evenly distributed on the outer wall of the body part, wherein the section of each additional part is in a crescent shape; a connecting rod is arranged at the upper end of each additional part; and each connecting rod is connected with the inner side of the valve deck through a swing rod.

Description

technical field [0001] The invention relates to the technical field of exhaust devices for liquid containers in industrial systems, in particular to a small quick exhaust valve. Background technique [0002] At present, the exhaust velocity of exhaust valves used in various industrial systems is closely related to its volume. The larger the volume, the greater the exhaust velocity; conversely, the smaller the volume, the less exhaust velocity. It is impossible to install a large-flow exhaust valve in a small space, and the larger the exhaust valve is, the higher the cost is, and the sticking rate of the exhaust valve spool is also high, resulting in a decrease in exhaust efficiency. Therefore, there is an urgent need for an exhaust valve that is not easy to get stuck, small in size, fast in exhaust, and low in cost. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and to provide a small quick exhaust...
