1. Product introduction
Cast steel globe valve is a common industrial valve, widely used in petroleum, chemical, electric power, metallurgy and other fields.
This paper will introduce the related knowledge of cast steel globe valve from the aspects of structural characteristics, working principle and application range.
First, structural characteristics
Cast steel globe valve is composed of body, valve cover, valve disc, valve stem and other parts.
It has compact structure, light weight, good sealing performance and flow regulation performance.
The valve stem and the valve cover are connected with threads for easy disassembly and maintenance.
The valve cover is provided with a sealing gasket to effectively prevent medium leakage.
Second, the working principle
The cast steel stop valve makes the disc move up and down by rotating the stem, so as to realize the cut-off or flow of the medium.
When the valve disc is raised, the valve disc is closely fitted with the seat, and the valve is closed; When the disc is lowered, the disc is separated from the seat, the medium passes through the valve, and the valve is open.
By adjusting the rotation Angle of the valve stem, the opening degree of the valve can be controlled to achieve the purpose of flow regulation.
3. Scope of application
Cast steel globe valves are suitable for piping systems with high temperature, high pressure and strong corrosive media.
Because of its compact structure, light weight and good sealing performance, it is widely used in petroleum, chemical industry, electric power, metallurgy and other industrial fields.
Especially in the petroleum and chemical industry, as a key equipment, cast steel globe valves can effectively control the flow and pressure of the medium, and the safety and stability of the production process.
Fourth, installation and maintenance
When installing the cast steel globe valve, the following points need to be noted:
1. The valve should be installed in a position that is easy to operate and maintain, and convenient for personnel to operate.
2. When installing the valve, pay attention to the connection between the valve stem and the valve cover to ensure that the connection is firm and prevent leakage.
3. Before using the valve, check the sealing performance of the valve to ensure that the valve works normally.
When maintaining cast steel globe valves, regular inspections and maintenance are required:
1. Check the sealing performance of the valve regularly. If leakage is found, replace the sealing gasket in time.
2. Regularly clean the inside of the valve, remove impurities on the valve disc and seat, and ensure the flexibility and normal operation of the valve.
3. When the valve is not used for a long time, anti-corrosion treatment should be carried out to prevent the valve from being corroded.
Summary: Cast steel globe valve, as a common industrial valve, has the characteristics of compact structure, light weight, good sealing performance, etc., and is widely used in petroleum, chemical, electric power, metallurgy and other fields.
