Large fluctuation of external flow pneumatic butterfly valve 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!
How to weld pneumatic butterfly valve?
Welding method? It is widely used in machinery, chemical industry, petroleum, metallurgy, food and other industries. Pneumatic butterfly valves are generally welded during connection. How should they be welded? Next, I will introduce you to the five steps of welding. You can also read the first step of the welding process site: when welding the pipe orifice size, you should first measure the length of the pipe, and then use the pipe knife to cut the pipe size.
Step 2: Clean the pipeline. Because the pipeline is metal, some waste slag will be generated in the pipeline due to oxidation, and some waste slag will affect the welding effect. Therefore, before welding, we should use emery cloth or paper to grind away the waste slag in the pipe.
Step 3: Use the pipe brush to clean the fittings. Cleaning the fittings can ensure that the welding hoses are clean and tinned.
Step 4: Control the welding time. Generally speaking, the length of weld bead you need depends on the length of solder.
Step 5: The use of flare heat pipe in line with the flare heat pipe is mainly to ensure that the weld of the pipe is evenly heated. It is worth noting that when using the torch, ensure that the flame is close enough to cover the diameter of the entire pipeline.
