Application Scenarios and Industry Adaptation Points of Explosion-Proof Solenoid Valves
As an automatic component with both explosion-proof performance and fluid control functions, explosion-proof solenoid valves are widely used in various high-risk industrial scenarios with flammable and explosive media, including petrochemical, coal mining, natural gas transmission, pharmaceutical, metallurgy, coating processing and many other industries, relying on their advantages of safety and reliability, strong adaptability and sensitive response. Different industries have differences in working conditions, medium characteristics and control requirements, and also have different adaptation requirements for the model, specification and material of explosion-proof solenoid valves. Only by accurately matching the industry needs can we give full play to their safety control role and ensure the orderly development of industrial production.
The petrochemical industry is one of the most extensive application fields of explosion-proof solenoid valves. In the production links of this industry, there are generally flammable and explosive liquids and gases such as gasoline, diesel, methanol and ethylene, and the production environment is mostly high temperature, high pressure and strong corrosion, which has extremely high requirements for the explosion-proof grade, corrosion resistance and pressure adaptation range of explosion-proof solenoid valves. In links such as petroleum refining, chemical synthesis, oil product storage and transportation, explosion-proof solenoid valves are mainly used for fluid cut-off, commutation and regulation. For example, in oil product transmission pipelines, explosion-proof solenoid valves are used to realize precise start and stop of oil product transmission, avoiding oil leakage and explosion accidents caused by valve leakage or misoperation; in chemical reaction kettles, explosion-proof solenoid valves are used to control the inlet and outlet of reaction media to ensure the safety and stability of the reaction process. The adapted explosion-proof grades are mostly Exd II BT4 and Exd II CT6, and the material is stainless steel to resist the erosion of strong corrosive media.
In the coal mining industry, the underground environment contains a lot of flammable and explosive substances such as methane and coal dust, which is a high-risk explosion environment. In addition, the underground space is narrow, with high humidity and much dust, which has strict requirements for the protection grade, dustproof and waterproof performance and impact resistance of explosion-proof solenoid valves. In the coal mine ventilation system, drainage system and gas drainage system, explosion-proof solenoid valves play an important control role. For example, in the gas drainage pipeline, explosion-proof solenoid valves are used to control the flow, start and stop of gas drainage. Once the gas concentration is detected to exceed the standard, the gas transmission can be quickly cut off to avoid explosion accidents caused by gas accumulation; in the underground drainage system, explosion-proof solenoid valves are used to control the start and stop of drainage pumps and the commutation of water flow, ensuring that underground water is discharged in time and the safety of mining operations. The explosion-proof solenoid valves selected in this industry are mostly flameproof and intrinsically safe types, with a protection grade of IP67 or above, which can adapt to the harsh underground working conditions of high humidity and much dust.
In the natural gas transmission and storage industry, the medium is flammable and explosive natural gas, with high transmission pressure and long transmission distance, which has extremely high requirements for the sealing performance, pressure adaptability and explosion-proof reliability of explosion-proof solenoid valves. In equipment such as natural gas long-distance transmission pipelines, urban gas transmission and distribution systems, and natural gas storage tanks, explosion-proof solenoid valves are used for natural gas cut-off, pressure regulation and commutation. For example, in the inlet and outlet pipelines of natural gas storage tanks, explosion-proof solenoid valves are installed. In case of leakage accidents, the natural gas transmission can be quickly cut off to prevent the accident from expanding; in urban gas transmission and distribution stations, explosion-proof solenoid valves are used to control the transmission and distribution of gas to ensure the safety and stability of gas supply. The explosion-proof solenoid valves selected in this industry need to have high-pressure sealing performance, with an adaptive pressure range of mostly 0.1-10MPa, an explosion-proof grade of not less than Exd II CT6, and have passed strict leakage tests to ensure zero fluid leakage.
In the pharmaceutical industry, some production links involve flammable and explosive solvents (such as ethanol, acetone, etc.), and the production environment has high requirements for hygiene grade. Therefore, explosion-proof solenoid valves not only need to have reliable explosion-proof performance, but also need to meet hygiene grade standards. In links such as pharmaceutical raw material synthesis, drug purification and solvent recovery, explosion-proof solenoid valves are used to control the inlet, outlet and circulation of solvents. The material is food-grade stainless steel, and the sealing parts are non-toxic, wear-resistant fluororubber to avoid medium pollution. At the same time, the explosion-proof grade is adapted to the explosive dangerous area of the workshop to ensure the safety and hygiene of the production process; in the cleaning link of pharmaceutical equipment, explosion-proof solenoid valves are used to control the transmission of cleaning fluid, adapting to high-temperature cleaning working conditions to ensure the thoroughness and safety of equipment cleaning.
In addition, explosion-proof solenoid valves are also widely used in industries such as metallurgy, coating processing and fireworks production. Different industries select different specifications and types of explosion-proof solenoid valves according to their own working conditions. In the selection and adaptation process, it is necessary to focus on key points such as explosion-proof grade, medium characteristics, pressure and temperature range, nominal diameter specification and installation method to ensure that the explosion-proof solenoid valve is accurately matched with the industry working conditions and give full play to its safety control role. With the increasing emphasis on production safety in various industries, the application scenarios of explosion-proof solenoid valves will continue to expand, and their industry adaptability will also continue to optimize, providing more reliable guarantee for the safe production of various high-risk industries.
