Abstract

The invention relates to a valve element and a valve comprising the valve element, and belongs to the field of valve equipment. The valve comprises a valve body and the valve element; a liquid outletand a liquid inlet are formed in the two ends of the valve body; the valve element is positioned in the valve body, and comprises a sealing end, a connecting end, an opening end and a rotating shaft;the connecting end is relatively fixed on the same side of the sealing end; the opening end is positioned between the connecting end and the sealing end, and is used for enabling fluids to pass through; the rotating shaft penetrates through the connecting end; and the connecting end realizes rotation and linear movement along with rotation of the rotating shaft to realize closing and opening of the valve. A sealing pad cannot be rotated along with the valve element, and is not rubbed with the inner wall of the valve body, so that the service life of the valve is greatly prolonged; and the valve has the characteristics of simple structure and convenient operation, and achieves broad popularization prospect.

Description

technical field

[0001] The invention belongs to the technical field of valve equipment, and in particular relates to a valve core and a valve including the valve core. Background technique

[0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief.

[0003] Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

[0004] At present, the common valves mainly include ball valves and butterfly valves, which are widely used, but there are many problems. During the rotation of ball valves and butterfly valves,...
