Product structure of electric butterfly valve:
The electric butterfly valves of our company can be divided into three categories according to the shape: curved bag type, membrane type and drum type. According to the sealing structure, it can be divided into five categories: pressure self sealing type, crimping type, flange clamping type, hoop seal type and hybrid type. Its structure consists of characteristic surface layer, high-strength skeleton layer and polar inner layer.
1. Characteristic surface layer: it protects the carcass, resists various external environmental pollution and seals;
2. High strength skeleton layer: control tension and bear load pressure;
3. Polar inner layer: it can seal the compressed air in the air chamber and bear the air pressure.
According to the basic structure, electric butterfly valves can be roughly divided into four categories, namely, ISO international standard type (ISO electric butterfly valve is a typical type commonly used in electric butterfly valves), compact type (compact type is also called J-type electric butterfly valve, which is a series of electric butterfly valves, called J-type compact electric butterfly valve) Ultra compact type (it is a long and short type of electric butterfly valve in the world), thin structure type (it is a compact type of cylinder diameter in electric butterfly valve, it is a piston sealed type, and its outer diameter is smaller than that of ultra compact type).
In addition to the basic four categories of structure, the electric butterfly valve also includes six basic categories, namely TU series, K series, Qiangli X series, Qiangli GX series, CU series and TB series commonly used in China.
1. TU series: it is also an international standard series, and also a worldwide series model of electric butterfly valve. All dimensions comply with ISO11910 electric butterfly valve standard.
2. K series: In TU series, this is a low type electric butterfly valve, which has a bottom mounting screw hole and a side inflation port, and can be used to connect with the pipeline system.
3. Qiangli X series: This is an electric butterfly valve with low and strong elastic pressure sealed by the plunger rod in the world, and has a bottom mounting screw hole and a side inflation port, which can be used to connect with the pipeline system.
4. Qiangli GX series: this electric butterfly valve is a new model launched by KALLER company, which is longer than the X series, and has a bottom mounting screw hole and a side inflation port, which can be used to connect with the pipeline system.
5. CU series: It is a very compact electric butterfly valve. Its smaller cylinder outer diameter can provide greater elastic pressure.
6. TB series: TB series electric butterfly valve is a new type of elastic component with high-pressure air as the working medium. It is small in size, large in elasticity, long in travel, stable in operation, precise in manufacturing, long in service life (one million times), flat in elastic curve, and does not need preloading.
