The main problems of the cast steel valve The main problems in the valve market are as follows: 1. Some operators purchase valves with no factory name, print famous brands and certificates of well-known manufacturers, and cause serious damage to the reputation of qualified valve enterprises. Second, the renovation of the valve, some operators through the re-painting of the old valve after the second sale, bringing serious safety risks to the project quality.
Valve history
The valve is the control device of the fluid pipeline. Its basic function is to switch on or off the circulation of the pipeline medium, change the circulation of the medium, change the flow direction of the medium, adjust the pressure and flow of the medium, and protect the normal operation of the pipeline equipment.
With the continuous development of modern industry, the demand for valves is increasing. A modern petrochemical plant requires tens of thousands of valves of various types, and the valve is used in a large amount. Frequent opening and closing, but often due to manufacturing, use selection, improper maintenance, run, run, drip, leak phenomenon, resulting in flame, explosion, poisoning, burn accident, or cause poor product quality, energy consumption, equipment corrosion Increased material consumption, environmental pollution, and even accidents such as production stoppages have become commonplace. Therefore, people hope to obtain high-quality valves, and also require the use of valves and maintenance levels. At this time, they are engaged in valve operators, maintenance personnel, and engineers. In addition to careful design, reasonable selection, and correct operation of the valve, it is necessary to timely maintain and repair the valve, so that the valve "run, run, drip, leak" and various accidents are minimized.
