Problems solved by technology

[0002] At present, on the oil inlet pipeline at the bottom of the coke tower of the delayed coking unit at home and abroad, some double electric four-way cock valves are used. There is a valve cavity in the valve body, the cock is set in the valve cavity, and one end of the valve stem extends to the valve cavity and connects with the cock. The other end is connected to the driving device through a ring bracket, and the valve sequential electrical control is realized through the electric control cabinet. The control of the double electric four-way valve is complicated, there are many fault points, the one-time purchase cost is high, the maintenance cost is high, and the steam loss Large, resulting in high production and operating costs of the device

Abstract

The invention relates to an electric four-way plug valve. The technical scheme includes that the electric four-way plug valve comprises a valve, a main feed inlet, a side feed outlet I, a side feed outlet II, a bypass outlet, a plug, a valve stem, a valve bonnet, a support, a packing gland, packing box blowing devices, a valve cavity blowing device, an electric head, a worm, a worm gear, an upperfriction disc, a lower friction disc, a transmission lead screw, a disc spring and a connector. The electric four-way plug valve has the advantages that the electric four-way plug valve is positionedon a coke tower bottom oil inlet pipeline of a device and is used for switching the flow directions of raw oil, accordingly, the raw oil from a heating furnace can be assuredly timely switched from acoke tower filled with coke to another preheated coke tower to continue to be operated, the device can be continuously and stably operated, is easy to electrically control, low in steam consumption, simple in structure and convenient to operate, and the manufacturing cost and the production and operation costs of the device can be reduced to a great extent.

Description

technical field [0001] The invention belongs to the field of control valves and relates to an electric four-way plug valve. Background technique [0002] At present, on the oil inlet pipeline at the bottom of the coke tower of the delayed coking unit at home and abroad, some double electric four-way cock valves are used. There is a valve cavity in the valve body, and the cock is set in the valve cavity. The other end is connected to the driving device through the ring bracket, and the valve sequential electrical control is realized through the electric control cabinet. The control of the double electric four-way valve is complicated, there are many fault points, the one-time purchase cost is high, the maintenance cost is high, and the steam loss Large, resulting in high production and operating costs of the device. Contents of the invention [0003] The purpose of the electric four-way cock valve described in the present invention is to provide a new solution for the shor...
