Describe
Insulation American standard ball valve
 
First, the structural characteristics
 
The ball valve is a valve that uses a ball with a circular through hole as a starting and closing member, and the ball rotates with the valve stem to realize the opening and closing action. Its advantages are:
 
1. The fluid resistance is small. When fully open, the cross-sectional area of ​​the ball passage, the valve body passage and the connecting pipe are equal, and the line is in a straight line.
 
Through, the medium flows through the ball valve, which is equivalent to flowing through a straight pipe, and the ball valve has the least fluid resistance in all kinds of valves.
 
2, the opening and closing is rapid, only need to turn the ball 90 ° when opening and closing, convenient and rapid.
 
3. The structure is simple, the volume is small, and the weight is light. In particular, its height is much smaller than the gate valve and the shut-off valve.
 
4 valve body is made of silicon melt glue for precision casting, and the appearance is smooth and beautiful.
 
5. The outer shell of the hair is welded with an insulation shell, which can effectively maintain the medium temperature.
 
Second, technical parameters
 
Nominal pressure: 1.6MPa-6.4MPa;
 
Nominal diameter: DN15~DN200;
 
Test: Hydraulic housing strength test - 1.5 times the maximum rated working pressure
 
            High pressure liquid seal test - 1.1 times the maximum rated working pressure
 
            Low pressure gas seal test - 0.6Mpa;
 
Applicable temperature: ≤120 ° C (soft seal) ≤ 425 ° C (hard seal);
 
Applicable medium: oil, gas, water, etc.;
 
Fourth, the relevant standards
 
1. Design and manufacture: GB/T 12237, API 608
 
2. Structure length: GB/T12221, ASME B 16.10
 
3. Connection flange: JB/T 79, ASME B 16.5
 
4. Pressure temperature: GB/T 12224, ASME B 16.34
 
5. Inspection test: GB/T 13927, API 598.
