1. Overview A 2.4Mt/a delayed coking unit adopts the process of two furnaces and four towers, and normally produces green coke for 24 hours. There are 16 high-temperature valves on the device. The medium...
Scouring Many factors that affect the scouring of the fluid particle, such as particle sizes, content, density and velocity in the fluid medium. For places with easy wear, the optimal valve is determined...
Dedicated valves refer to valves that can be used in various special environments and adapt to various complex working conditions. A dedicated valve is a general mechanical product widely used in the...
3. Strengthening the maintenance and management of valves in gas transmission stations 3.1 Paying attention to the selection and training of valve manufacturers The valve is a very important device for...
Abstract: The valve plays a very important role in the gas transmission station. According to different conditions and environments, the valve also plays different roles in the actual use process. Therefore,...
Stainless steel valves are usually used in situations where the working medium is corrosive to a certain extent. For any kind of valve material, the ability to resist the corrosion of the working medium...
4. The calculation of the opening and closing torque of the valve After the main structure of the valve and the supporting and sealing structure at both ends of the valve body are determined, the maximum...
The large-diameter telescopic hydraulically controlled slow-closing butterfly valve adopts the integrated form of machinery, hydraulic control, electric control and computer, which can replace gate valves,...
According to the actual operation of the power station, the structural design of the valve stem should be further improved and perfected, the torsional moment that the valve stem can bear should be increased,...
1.4 Tests (1) Finite element simulation tests Through the preliminary analysis of the reasons for the failure of the valve stem of the above-mentioned failures, it is understood that there is a certain...
