The clamping device commonly used in the production of double flange electric ball valve requires more time for clamping, so it is often used for clamping device quickly in mass production. This device is mainly used for wheel rotation around the axis to produce clamping effect. It is characterized by fast clamping action, small clamping distance and less self-locking than double flange electric ball valve clamping device. The clamping force used for is also much smaller than that for thread clamping.
Therefore, it is mostly used in the case of small deviation, no vibration or small vibration of the expansion joint. It is used in the clamping device. Because of the small contact area, it is easy to damage the surface of the expansion joint. Therefore, it is generally not used to directly compress the expansion joint, but to compress the expansion joint through cushion blocks or pressing plates. There are two commonly used wheels: circle and curve. The circle is used as a disc, which is simple in structure, convenient in manufacturing and widely used in production. The offset between the rotation center and the center of the circle is called for the moment. There is a handle on the double flange electric ball valve, which is used to rotate and clamp the pipe fittings. The clamping device of double flange electric ball valve shall be self-locking after clamping the expansion joint. This feature consists of the diameter used for the working surface and the distance used for the working surface. To determine.
