Product Description

The fixed ball valve is a kind of valve commonly used in power plants and other industrial occasions, its main function is to control the flow of pulverized coal and ash. The following is a detailed introduction to the fixed ball valve of pulverized coal discharge:
Definition of pulverized coal discharge fixed ball valve
Pulverized coal ash discharge fixed ball valve is a kind of ball as a cut-off element of the valve, usually by the valve body, ball, valve stem, seals and so on. The valve is suitable for controlling the flow of pulverized coal and ash under high temperature and high pressure environment.
Second, the characteristics of pulverized coal injection ash discharge fixed ball valve
(1) High temperature and high pressure: pulverized coal ash discharge fixed ball valve can operate normally at a temperature of up to 450 ° C and a pressure of 6.4MPa, with good high temperature and high pressure resistance.
(2) Reliable seal: the valve adopts multi-layer cemented carbide sealing structure, with excellent wear resistance and long life.
(3) Good fluid characteristics: coal injection ash discharge fixed ball valve fluid characteristics are superior, pressure loss is small, flow capacity is large.
(4) Easy operation: the valve adopts two driving methods, manual and electric, simple and convenient operation.
Third, the application of coal injection dust discharge fixed ball valve
Pulverized coal ash discharge fixed ball valve is widely used in coal-fired power plants, metallurgy, petrochemical and other industrial fields. In the coal-fired power plant, the fixed ball valve of pulverized coal discharge is mainly used in the pulverized coal conveying pipeline and ash treatment pipeline, which plays the role of controlling and regulating the flow rate.
Fourth, the installation and maintenance of pulverized coal ash discharge fixed ball valve
(1) Installation: In the installation process of pulverized coal discharge fixed ball valve, it is necessary to pay attention to the following points:
The valve should be strictly inspected before installation, and ensure that the connection between the components is firm and reliable;
Select the appropriate sealing material and grease to ensure the sealing performance and flexibility of the valve;
In the installation should be based on the actual situation to choose the appropriate installation position and mode, to avoid the improper position of the valve and affect the normal use of the valve.
(2) Maintenance: The fixed ball valve needs to be regularly inspected and maintained during operation to ensure its normal work. The specific operations are as follows:
Regularly clean the inside of the valve;
Check whether the sealing surface and seals are worn and damaged, and replace them in time;
Check the valve stem, piston rod and other parts of whether there is deformation or wear, if necessary, should be repaired or replaced in time.
Five, coal injection ash discharge fixed ball valve development trend
1. The degree of automation: with the continuous progress of technology, the fixed ball valve of pulverized coal discharge will be more intelligent and automated, and can achieve remote control and monitoring functions to improve production efficiency and safety.
2. Tight structure design: In the future, the tight structure design of pulverized coal ash discharge fixed ball valve will get more attention to reduce air leakage, powder leakage and other problems, and improve its sealing performance.
3. Material selection optimization: material selection will be more strict, the use of high temperature resistance, corrosion resistance, wear resistance and other special materials, in order to extend the service life of pulverized coal discharge fixed ball valve.
4. Improved processing capacity: The future pulverized coal ash discharge fixed ball valve will have a stronger processing capacity, capable of greater flow and pressure range.
5. Environmental protection and energy saving: In the pulverized coal discharge process, energy saving and environmental protection will become an important issue. Therefore, the future pulverized coal ash discharge fixed ball valve will pay more attention to energy saving and environmental protection, the use of more environmentally friendly materials and processes, reduce energy consumption and pollution.
