What are the core factors that affect the processing accuracy of the solenoid valve cavity on the reaction speed? This article mainly starts from the technical level and the practical application perspective, starting from the three most important factors of smoothness, straightness and corner smoothness. According to Ruwei Valve Engineer Ten years of research and test data have analyzed three factors that affect the change of solenoid valve response speed.
With the continuous development of modern industry, the demand for valve supply is also increasing. A modern petrochemical plant requires tens of thousands of valves, which makes the valve consumption large. Frequent opening and closing, but often due to improper manufacturing, use, selection, maintenance, running, emitting, dripping, leakage, etc., which cause flames, explosions, poisoning, burns and other accidents, or cause valve product quality is inferior, energy consumption increases, Corrosion, increased material consumption, environmental pollution, and even the shutdown of gas stove solenoid valves, etc., these are the problems we often encounter, so people hope to obtain high-quality valves, but also require improving the performance of the valves and improving the maintenance of the valves. At this time, new requirements are put forward for valve personnel, maintenance personnel, and engineering and technical personnel. In addition to careful design, reasonable selection, and correct operation of the valve, it is also necessary to maintain and repair the valve in time to make the valve "running, "Emissions, drips, leaks" and various accidents are minimized.
Under normal circumstances, the valves used for low pressure non-corrosive fluids are made of cast iron or cast copper; cast steel or forged steel used for high and medium pressure valves; alloy steel used for high temperature or high pressure valves; valves used for corrosive fluids use stainless steel , Plastic, made of corrosion-resistant materials for high-temperature solenoid valves (such as copper-nickel-molybdenum alloys, titanium alloys and lead alloys, etc.) or cast iron, cast steel lined with corrosion-resistant materials.
According to the different functions, valves can be divided into six types: cut-off valve, regulating valve, check valve, diverter valve, safety valve, and multi-purpose valve.
Shut-off valves are mainly used to cut off fluid channels, including globe valves, gate valves, plug valves, ball valves, butterfly valves, diaphragm valves, pinch valves, etc.; regulating valves are mainly used to cut off the pressure and flow of fluids, including regulating valves, throttle valves, etc. , Pressure reducing valve and floating ball regulating valve, etc.; check valve is mainly used to prevent the reverse flow of fluid; shunt valve is mainly used to distribute the flow direction of fluid, or to separate two-phase fluid, including slide valve, multi-way valve, drain Valves, emptying valves, etc.; safety valves are mainly used to protect boilers, pressure vessels or pipelines from overpressure. Multi-purpose valves are valves with multiple functions. For example, stop stainless steel solenoid valves and return valves can cut off fluids or Cut off the fluid.
According to the nominal pressure, industrial pipeline valves can be divided into vacuum valves, low-pressure valves, medium-pressure valves, high-pressure valves, and ultra-high-pressure valves; according to the working temperature, the valves can be divided into normal temperature valves, medium temperature valves, high temperature valves, and low temperature valves; Valves can be classified according to the type of drive device, the connection method with the pipeline, and the material of the valve body. The valves can be named separately or in combination according to different classification methods, and the valves can also be named according to the structural characteristics or specific uses of the opening and closing device.
