Abstract

The invention discloses a freon air bottle valve. The freon air bottle valve comprises a valve body and a valve rod; a runner is formed in the valve body; a sealing pad sleeves the middle part of thevalve rod; a valve hole, cooperating with the sealing pad, is formed in the middle part of the runner; the valve body is provided with an outlet communicating with the upper part of the runner and aninlet communicating with the lower part of the runner; a spring base is arranged in the runner; the spring base is provided with a spring for pushing the valve rod to approach the valve hole; a through hole is formed in the spring base; a valve plate, rotationally connected, is arranged in the through hole; and a slide block, driven by the valve rod to open the valve plate, is arranged in the spring base. The freon air bottle valve reduces the freon leakage.

Description

technical field [0001] The invention belongs to the field of freon storage, in particular to a freon cylinder valve. Background technique [0002] At present, Freon is usually stored in a special gas cylinder or tank after being subjected to high pressure, and is usually provided with a valve, which is opened or closed by a handle. Chinese Patent Publication No. CN106678441A discloses a valve structure for a low temperature fire extinguisher, including a valve body; The outlet of the valve body connected with the main channel, the lower port of the main channel constitutes the inlet of the valve body, the main channel includes a tapered valve hole whose inner diameter gradually decreases from bottom to top; and a valve core for controlling the on-off of the flow channel of the valve body, The valve core includes a valve stem inserted in the main channel, an upper seal ring on the valve stem that is arranged on the valve stem and forms a sealing connection with the main chan...
