The metal pneumatic butterfly valve informs you that the elasticity of the spring damper is critical
The metal pneumatic butterfly valve meets customer inquiries about the use of spring shock absorber in cars? What is the significance of spring shock absorber in automobile? The spring shock absorber will not be too stable or easy to be damaged during the driving of the car. However, the elasticity of the spring shock absorber is a key issue. If the elasticity is not well adjusted, it may directly lead to the vibration or spring damage of the car components.
The greater the damping force of the spring damper, the faster the vibration will be eliminated. However, excessive damping force will lead to the failure of the elastic element to play its role fully, and even excessive damping force may lead to damage of some connecting parts and frame.
In order to harmonize the elastic element and the shock absorber, the following requests are made for the shock absorber:
1. During the suspension tightening stroke (the stroke when the axle and frame move close to each other), the damping force of the shock absorber should be small, so that the elasticity of the elastic elements can be fully applied to mitigate the impact;
2. In the suspension stretching stroke (the stroke that the axle is relatively far away from the frame), the assembling force of the shock absorber should be large, so as to reduce the vibration quickly; 3. When the relative speed between the axle (or wheel) and the frame is too high, the shock absorber should be able to automatically increase the cross-sectional area of the fluid flow channel, so that the damping force is always within a certain limit, so as to avoid being subjected to excessive impact loads.
At present, two-way acting cylinder shock absorbers are widely used in automobiles. The shock absorbers that can reduce vibration in both the tightening and stretching strokes are called two-way acting shock absorbers. Another kind of shock absorber only works during the stretching stroke. It is called one-way shock absorber.
In fact, many times the car runs on a too smooth road. When cornering, the spring shock absorber is constantly maintaining the car, making the car tilt to a certain extent, but not roll over. This is the spring shock absorber working.
Nowadays, we buy more and more private cars. Driving actually has certain risks. We must do a good job in the maintenance of cars. We must do a good job in the inspection to prevent the car from presenting an accident. We should check the spring shock absorber, because the spring shock absorber maintains the car during the bending process!

Stainless steel pneumatic butterfly valve has natural sanitary characteristics
When we mention stainless steel, we may think of stainless steel kitchenware and tableware used at home for the first time, such as stainless steel pots, stainless steel hot pots, stainless steel basins, stainless steel spoons, etc. These tableware bring great convenience to our diet in daily life, and the sanitary conditions are safe and reliable. Steel is an alloy with relatively stable chemical properties formed by participating in carbon and other elements in iron. With the participation of nickel, chromium, manganese, vanadium and other elements in carbon steel, the stability has been greatly improved, making the alloy have good acid and alkali corrosion resistance characteristics, so the service life of the greatly improved steel alloy is called stainless steel.
Because of the stability of stainless steel, making tableware with stainless steel products will not have adverse effects on human body. In recent years, people's demands for food hygiene have improved from time to time. In the food industry, more and more stainless steel equipment and containers are used. For example, more and more stainless steel pneumatic butterfly valves will be used in the hoses for sugar adding in food factories and for liquor conveying in distilleries.
Recently, when many customers questioned the stainless steel pneumatic butterfly valve, they asked whether there was food level standard certification. When the food hose was used, the rubber material of the food cloth clip hose and the silicone hose would have a certain impact on the food hygiene, and there were strict hygiene access standards for them. However, the stainless steel pneumatic butterfly valve itself has natural sanitary conditions, and does not need food level standard certification. At present, the country has not issued relevant standards.
