Washable water supply rotary electric control valve

Abstract

The invention provides a washable water supply rotary electric control valve which comprises an electric device, a filler ring, a V-shaped filler, a filler gland, a valve cover, bolts, nuts, a filler,a valve rod, a connector, a valve cage, a valve core, a valve body, a bottom cover, a filler ring, a sealing gasket, a cleaning joint and a sealing gasket. The valve body is provided with an inlet and an outlet in the horizontal direction, a cylindrical center is used for installing the valve seat which is equipped with a valve core with a closing fit, both the valve seat and the valve core are cylinders perpendicular to each other, the valve seat is a cage valve seat, and the valve core is also a cage valve core. The valve rod is fixed to an upper end surface of the cylindrical cage valve core which can rotate in the outside cylindrical cage valve seat, and the cage valve seat is slidingly matched with the cage valve core. The valve cover and the valve body are fixed by the bolts and thenuts, the center of the valve cover is provided with a sealing filler which coats the valve rod, and the sealing filler comprises the filler ring, the V-shaped filler and the filler gland from the top to the bottom. The upper end of the valve rod extends out of the sealing filler of the valve cover, and the upper part of the valve rod is an electric device.

Description

Technical field: [0001] The invention relates to an electric control valve, especially a washable water supply rotary electric control valve, which is widely used in petroleum, chemical industry, electric power, metallurgy and other industries, and the pressure can reach steam above 30.0 MPa. Background technique: [0002] It is widely used in the steam pipeline control system of the existing power station, metallurgy, chemical industry, oil field and other fields. The high-pressure valve is especially used to cut off the high-pressure steam medium. It is a special valve that cuts off the steam on the pipe network; the shortcomings of the existing traditional products: it is not resistant to high pressure. In the high-temperature and high-pressure steam pipeline, the water in the steam Driven by high-speed steam, the particles will bring huge impact damage to the valve. Especially at the moment when the valve is opened and closed, the flow rate increases instantaneously, ca...
