Overview

The opening and closing of the gate valve $r $n in high-temperature power plants are controlled by electric devices, which are equipped with motors, reducers, torque control mechanisms, on-site operating mechanisms, manual and electric switching mechanisms. In addition to on-site operation, remote operation can also be performed.

Product Details

High temperature power station gate valveMainly suitable for cutting off or connecting pipeline media in various systems of thermal power plants. Applicable media: non corrosive media such as water and steam. The characteristics of power station valves compared to other valve products are high temperature and high pressure, and a self sealing design. The higher the pressure, the more reliable the seal. Due to its unique performance, technical characteristics, and working conditions, the product has also developed unique features that cannot be replaced by other products.

High temperature power station gate valve

1. Adopting a pressure self tightening sealing structure, an elastic gate plate, and welded connections at both ends of the branch pipes.
2. The sealing surface of the valve seat is made of cobalt based hard alloy plasma spray welding, which has good wear resistance and abrasion resistance.
The sealing surface of the valve disc is hardened and nitrided.
3. The surface of the valve stem is treated with corrosion-resistant nitriding, which has good corrosion and abrasion resistance.
4. The opening and closing of valves are controlled by electric devices, which are equipped with motors, reducers, torque control mechanisms, on-site operating mechanisms, manual and electric switching mechanisms. In addition to on-site operation, remote operation can also be performed. According to user requirements, the 2SA30 series produced by Yangzhou Electric Power Equipment Repair Factory with Siemens technology, the A series produced by ROTORK from the UK introduced by Shanghai Automation Instrument Co., Ltd.'s 11th Factory, and the RA series electric head produced by Ruiji Measurement and Control Equipment Co., Ltd. can be selected.

Installation Instructions

1. Electric gate valves must be installed vertically, with the valve stem facing upwards, and the flow of the medium can enter from any side.
2. The electric device is installed in an environment with an ambient temperature of 20 ° C to+40 ° C, a relative humidity of ≤ 80%, no corrosion, and no corrosive gases.
3. When the temperature of the pipeline is below 350 degrees Celsius, the electric device uses semi fluid lithium based lubricating oil (Q/sYl002-65). When the temperature of the pipeline is above 350 degrees Celsius, GB492-2N4 sodium based grease is used for lubrication.
