How to modify the pneumatic butterfly valve correctly?
Xiao Bian meets everyone again. Before you rush to work, let me show you how to modify the pneumatic butterfly valve!
In theory, the modification of pneumatic butterfly valve is to replace it with a pneumatic butterfly valve with hard damping, good quality and can fully cooperate with the spring. It is most important to select a group of suitable pneumatic butterfly valves. It is particularly difficult to achieve a compromise between warmth and controllability. A set of adjustable damping pneumatic butterfly valves can improve the applicability, especially on the changeable road. It seems that the adjustable pneumatic butterfly valve can seriously consider the effect of the compression resistance of the pneumatic butterfly valve and the hardness of the spring. A set of springs only needs one performance, and the only way to change the hardness of the spring is to change another set of springs with different elastic coefficients, The adjustable pneumatic butterfly valve can compensate for this shortcoming. The most difficult problem in the process of suspension modification is the matching of pneumatic butterfly valve and spring. If your car lowers the body by more than 2 inches or the spring hardness increases by more than 20%, you must change the spring pneumatic butterfly valve together. The hard shock absorber and the hard spring should match each other. Because the hardness of the spring is determined by the weight of the car, the heavier car needs a harder pneumatic butterfly valve.
Therefore, the pneumatic butterfly valve on racing cars or high-performance cars is harder than that on ordinary cars to match with a harder spring. If the pneumatic butterfly valve is too soft, it will form the swing of the body up and down. If it is too hard, it will form too much damping, making the spring unable to operate normally. Moreover, the damping effect of the pneumatic butterfly valve will cause the change of the vehicle height when driving. The softer spring (progressive), coupled with the harder adjustable spring, will damp the pneumatic butterfly valve to make up for the lack of spring strength with the hardness of the shock absorber, With freely adjustable damping, a high degree of road compliance is achieved. Generally speaking, a soft spring can provide better warmth and better tracking when traveling on rough roads. If the spring is very soft, it is easy to sit on the bottom, that is, to use up the suspension travel.
Assuming that the bottom sitting occurs during cornering, it can be seen that the elastic coefficient of the spring becomes infinite (there is no room for contraction), and the body will produce an immediate weight transfer, which constitutes a loss of traceability. Assuming that this car has a long shock absorption travel, it may be allowed to avoid the occurrence of bottoming, but the relative body will also become very high, and a very high body means a high body center of gravity. The up and down of the body center of gravity has a decisive impact on the handling performance, so too soft pneumatic butterfly valve will cause obstacles in the handling.

The rotary compensator first uses a press to mold the sealing materials. The density required for molding is not too dense, and the plasticity is adhered to. Then, put N rings of the packing ring (determined according to the product request) into the packing chamber, add some components that delay oxidation, and then stop the secondary forming under the relative pressure of the hydraulic press (the hydraulic press surpasses the technical wrench in strength and average), so that the packing rings are integrated, and then reach the density of the traveling packing, so that the sealing performance of the packing is good, Make sure that the product will not leak within 15-20 years.
Rotary compensator application equipment:
1. When the compensator is welded with the pipeline, the groove shall be stopped at the junction of the pipeline. After the welding, the flaw detection shall be stopped according to the request of the pressure vessel, and the hydraulic test shall be stopped. During the test, the sealing and pressing parts shall be adjusted until there is no leakage. The stress on all parts shall be the same, so as to better use the torque wrench.
2. The sliding support and fixed support shall be designed according to the equipment. In order to ensure that the pipeline has no lateral displacement and is elastic along the axial direction, the ordinary equipment of the compensator shall be near the fixed support, and the guide support shall be set on the movable side. At the turning of the pipeline, the necessary equipment shall be used to fix the support.
3. The thermal insulation and waterproof structure of the compensator can be the same as that of the pipeline, but it does not bind the elastic pipe.
4. If the inner tube is pulled out carelessly when the equipment is in use, the equipment shall be installed on the pipeline before reassembly and test.
5. The compensator can be installed with large equipment length L under various temperatures, without pretension or preloading. If the loose length of the casing is misaligned, the casing can be pushed or pulled out, and the equipment can be installed after calibration and compaction.
