introduction：xiangjiao tanhuang Rubber spring rubber spring A spring made of rubber。The elastic modulus of rubber spring is small，Large elastic deformation after loading，To absorb shock and vibration。It can be subjected to multiple loads simultaneously，However, the resistance to high temperature and oil is worse than that of steel springs。Rubber springs are commonly used in mechanical equipment、Vehicle walking mechanism and suspension，Damping and buffering effect。The rubber spring can be designed into various structural forms according to the work needs（See picture[Structural form of rubber spring]），Commonly used are cylindrical shapes、Truncated cone、rhomboid、Ring sleeve and combined type, etc

introduction：Butterfly valve Introduction:The opening and closing part of the butterfly valve is a disc shaped butterfly plate，Rotates around its own axis in the valve body，The valve that can be opened and closed or adjusted is called the butterfly valve。Butterfly valve fully open to fully closed is usually less than90The degree of ，The butterfly valve and the butterfly rod themselves have no self-locking force，For positioning the butterfly plate，The worm gear reducer should be installed on the valve stem。Using worm gear reducer，Not only can the butterfly plate have self-locking ability，Stop the disc in any position，It can also improve the operating performance of the valve。 Industrial special butterfly valve features high temperature resistance，The applicable pressure range is also high，The nominal diameter of the valve is large，The valve body is made of carbon steel，The sealing ring of the valve plate is made of gold
