Understanding the details of pneumatic tire
Today, the editor of Shanghai Dongfeng Pump Valve Factory will share with you the details of pneumatic tires. Please read the following articles carefully:
Pneumatic tire is also known as air stroke conditioner and air vibration isolator. Pneumatic butterfly valve can be divided into three categories according to its shape: bag type, membrane type and sleeve type. According to the sealing structure, it can be divided into four categories: pressure self sealing type, rim clamping type, hoop sealing type and hybrid type. The load of pneumatic butterfly valve is mainly accepted by the cord. The number of layers of cord is mainly composed of two layers. The special request product is composed of four layers of cord. The inner layer is mainly used for sealing, while the outer layer is used for maintenance in addition to sealing.
According to the connection mode, it can be divided into three categories:
One is the fixed flange connection type. The size of the edges at both ends of the pneumatic butterfly valve is equal to or slightly smaller than the maximum outer diameter of the crankcase. After drilling several holes, use the blue ring and the end plate to fasten the connection;
The other type is the looper flange connection type. The size of the edges at both ends of the pneumatic butterfly valve is much smaller than the maximum outer diameter of the curved capsule, and there is no need to drill holes. A special flange ring is used to fasten the connection with a common end plate;
The third type is a self sealing type, which is not connected by flange, but is pressed into the end plate and self sealed when compressed air is filled.
