What are the characteristics of adjustable pneumatic butterfly valve
What are the differences between installing adjustable shock absorbers on cars and other types of pneumatic butterfly valves? What are some characteristics of adjustable shock absorber that make people more inclined to choose it? Let's find the answer to this riddle by Songxia Xizhen metal pneumatic butterfly valve!
Literally, the damping of this kind of shock absorber can be adjusted, which can be divided into traditional adjustable damping shock absorber and electronically controlled variable damping shock absorber (usually using electromagnetic control). The traditional adjustable damping damper needs more complex electromechanical devices, and some also need subordinate hydraulic systems. With complex structure and high cost, it is difficult to make progress on ordinary models? In contrast, the electronically controlled electro/magnetorheological fluid shock absorber is more flexible in application and smaller in volume and weight, while the magnetorheological fluid shock absorber has become a mainstream technology due to its more stable working state than the electro rheological fluid shock absorber, and has been equipped in many models. Similarly, the electromagnetic shock absorber can also be set and adjusted manually, or the vehicle can automatically adjust the damping of the shock absorber according to the collected dynamic information to complete dynamic control? 　? ? ? ? ?

Introduction to various trace elements contained in stainless steel pneumatic butterfly valve material
Taking 304 stainless steel pneumatic butterfly valve as an example, 304 stainless steel hose mainly contains carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, etc.
carbon
Carbon is a very common element, which exists in the atmosphere and crust in many ways. Carbon has been recognized and applied for a long time. A series of compounds of carbon - organic matter is the basis of life.
Character Carbon is usually a odorless and tasteless solid. The physical properties of simple carbon depend on its crystal structure, appearance, density, melting point, etc. Carbon exists in all steels and is the most important hardening element. It helps to increase the strength of steel. We usually hope that tool grade steel has more than 0.6% carbon, also known as high carbon steel.
chromium
The effect of chromium on stainless steel is to increase wear resistance and hardness, and the most important is corrosion resistance. Stainless steel is considered to be stainless steel if the chromium content is more than 13%. Of course, if we don't take care of ourselves properly, all steel will inevitably rust.
manganese
Manganese is an important austenite stabilizing element, which helps to generate texture structure, increase stability, strength and wear resistance. The steel is deoxidized inside during heat treatment and coiling, which is one of the most steel used for cutting today, except A-2, L-6 and CPM420V.
molybdenum
Carburizing agent can prevent steel from becoming brittle and adhere to the strength of steel at high temperature. In many steels today, air hardened steels (such as A-2, ATS-34) always contain 1% or more molybdenum, so that they can become hard in air.
nickel
The effect of nickel on stainless steel lies in its strength, corrosion resistance and toughness.
silicon
Helps increase strength. Like manganese, silicon is used to maintain the strength of steel in the consumption process of steel.
phosphorus
Phosphorus is a harmful element, which reduces the plasticity and toughness of steel, presents cold brittleness, and can significantly improve the strength of steel. At the same time, it can improve the atmospheric corrosion stability. The content should be limited to 0.05%.
sulfur
Sulfur is a harmful element, which makes steel hot brittle, and its content is limited below 0.05%. Basic performance and application of corrugated pneumatic butterfly valve Corrugated pneumatic butterfly valve has many characteristics such as good flexibility, fatigue resistance, high temperature resistance, upper and lower temperature resistance, corrosion resistance, etc. Its service life is much longer than other hoses (rubber and plastic hoses), so it also has high comprehensive economic benefits. With the development of modern industry The demand for high pressure resistant corrugated pneumatic butterfly valves is also growing.
