Novel tap

Abstract

The invention aims to provide a novel tap with convenient use and good air tightness, which comprises a shell and a through pipe, wherein the shell is in a cylindrical shape of which the upper end is opened; both sides of the upper part of the shell are provided with notches; the lower end of the shell is provided with an outlet; the inside of the shell comprises a middle shell and an inner shell; the middle shell is in a cylindrical shape of which the lower end is opened; both sides of the middle shell are provided with notches; the inner shell is in a conical shape with an opened upper end and a gradually narrowed lower end; both sides of the upper end of the inner shell are fixedly provided with two wings; the lower part of the inner shell is provided with an elastic plastic cover; andthe elastic plastic cover is in a conical shape of which the upper end is opened. The elastic plastic cover has elasticity; and when the two wings deviate from initial positions, the plastic cover plays a role of restoring the two wings, the plastic cover does not cut off water flow but not air flow at the moment of blocking the outlet, the phenomenon of air flow backward cannot be generated, andliquid in storage equipment is ensured not to contact air. The novel tap is simple in structure and low in cost, and achieves the aims of convenient use and good air tightness.

Description

technical field [0001] The invention relates to a valve switch, in particular to a novel faucet. Background technique [0002] The structure of an ordinary faucet is divided into three parts: the valve body, the valve stem, and the valve core. There is also a gland on the upper part of the body, under which there is a packing to prevent water from leaking from the valve stem, and the valve core and the valve stem are generally connected by a looper, that is, there is a hole in the middle of the top part of the valve stem, and the valve core is processed during processing. A rod of about 1 cm (slightly smaller than the hole diameter on the valve stem) is left to match it, which will make the valve core move flexibly, and there is a piece of rubber at the bottom of the valve core to match the sealing surface of the valve body. When the valve stem rotates clockwise, the valve stem drives the valve core to move downward, and when the rubber on the valve core is in full contact ...

Problems solved by technology

For the faucets mentioned above, when the passage is closed, air bubbles will return to the passage under the action of atmospheric pressure, which may affect the confidentiality of the passage.

For example, in the wine industry, many wine tanks or barrels use taps to discharge the wine. At this time, the general taps cannot guarantee the airtightness of the wine.
