Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 As shown, the closed electro-hydraulic gate valve includes a hydraulic station and a gate valve that are used in conjunction with each other. The gate valve includes a gate body 1 and a cylinder 2 that are connected to each other. After cooperation, the cylinder 2 is connected to the hydraulic station; fully sealed The structural gate body 1 is made of stainless steel; among them, the gate body 1 is sealed with high temperature resistant asbestos, the gate body 1 is provided with an inspection port 3, and the bottom of the gate body 1 is provided with a wear-resistant lining plate 4.

[0014] Working process: The hydraulic station is used as the power source to drive the cylinder 2. The cylinder 2 is connected to the gate body 1 made of stainless steel. The gate body 1 is opened and closed by the drive of the hydraulic s...

Abstract

The invention discloses a closed electro-hydraulic gate valve and belongs to the technical field of gate valves. The closed electro-hydraulic gate valve comprises a hydraulic station and a gate valve used with each other. The gate valve comprises a gate body and a cylinder connected with each other. After fitting, the cylinder is connected with the hydraulic station. The full-closed gate body is made of stainless steel. The closed electro-hydraulic gate valve is powered by the hydraulic station, effective in opening and closing, free of jamming, safe and reliable. In addition, the special gate body is ensured to be free of gas leakage during closing, and the closed electro-hydraulic gate valve is safe and durable. The closed electro-hydraulic gate valve is compact in structure, easy to maintain, and suitable for popularization and application in production and operation.

Description

technical field [0001] The invention belongs to the technical field of gate valves, in particular to a closed electro-hydraulic gate valve. Background technique [0002] CDQ is a coke production process. Usually, the coke produced in the CDQ furnace passes through the gate valve and then enters the vibrating feeder to output the coke; the gate valve is between the CDQ furnace and the vibrating feeder. The checkpoint components in the room are used for opening and closing, feeding, maintenance and closing, etc. The normal use environment of this equipment is a high-temperature gas environment, and the requirements for transmission and sealing performance are relatively high. [0003] Most of the traditional flapper valves are old-fashioned screw drive methods, which will often get stuck after a long time of use, causing the equipment to fail to work normally; the flapper valve is sealed with ordinary sealant, which cannot withstand high temperatures, and the use time After a...
