Abstract

The invention relates to a rotary sealing feeding valve which comprises a valve casing, side flanges which are symmetrically arranged and a star-shaped rotor, wherein the side flanges are fixedly installed at the front side and the back side of the valve casing; a main shaft is supported between the side flanges; and the star-shaped rotor is supported between two side flanges in the valve casing. The invention is characterized in that the space between each side flange and the valve casing is divided into a plurality of sealed chambers by the star-shaped rotor; a pressure-reducing balanced opening and a pressure-increasing balanced opening are arranged on the valve casing; and the valve casing also comprises a feeding opening and a discharge opening. The rotary sealing feeding valve is a rotary valve which is suitable for continuous feeding in the environment with pressure difference and temperature difference.

Description

Technical field: [0001] The invention is a valve or a gate, in particular a rotary valve suitable for continuous feeding in an environment with pressure difference and temperature difference. Background technique: [0002] Rotary feeding valves are widely used in building materials, metallurgy, electric power, chemical industry, tobacco machinery and other industries. At present, the rotary feeding valve used for conveying granular piles or powdery materials usually includes a valve housing and a star-shaped rotor arranged in the cavity of the valve housing. According to the needs of different use occasions, the star rotor and the inner wall of the valve housing cavity can be non-contact, that is, there is a gap between the top of the vane and the inner wall of the valve housing cavity; or contact, that is, the top of the blade and the inner wall of the valve housing cavity There is no gap between the inner walls, that is, the rotary seal feeding valve. The inlet and outle...
