Differential analysis of valve oil and water solenoid valves

Oil solenoid valve: a wide variety of oil products, sealing technology is one of the key. Oil resistant rubber is only the name of the category. Different oil or even the same kind of oil contains different impurities, so we need to choose different kinds of oil resistant rubber.
For example, lead-free gasoline is not necessarily resistant to unleaded petrol. In recent years, with the increase of sales volume of special solenoid valves, the service life of special oil resistant rubber has also been increasing. The viscosity of oil varies greatly, so solenoid valves with different structures should be selected. High viscosity oil is often circulated under high temperature, so solenoid valve will also solve the problem of high temperature resistance. Fuel also needs to meet the explosion protection requirements.
Water solenoid valves: water solenoid valves are always considered to be the simplest. In fact, water is divided into water, industrial water, industrial wastewater, irrigation water, sea water and many other categories, its corrosion performance, the degree of cleanliness, and the selection of different electromagnetic valves. Although tap water is the most popular, the performance requirements of valves are different.
For example, the solenoid valve for fire control is very important for action reliability. Even if the ordinary manual valve does not open and shut for a long time, it is difficult to open quickly. In recent years, high-rise buildings have sprung up, and the technology of fire solenoid valves in China has also matured. For example, the waterworks need to use the solenoid valve in the inverted siphon Road, but this kind of solenoid valve should be in the state of pressure, work reliably in the vacuum state, and never have internal leakage, and still should be flexible in the condition of low water cleanliness. In addition, the sprinkler electromagnetic valve has been gradually applied with the development of agriculture and garden forestry in China.
