进口四偏心球阀-美国阿卡迪亚品牌

进口四偏心球阀Product Description:

The four eccentric, spherical and conical sealing two-way pressure ball valve includes the valve body, the valve seat and the C-shaped ball. The valve seat is fixedly arranged inside the valve body. The C-shaped ball is arranged inside the valve body through the movement of the valve rod, and the C-shaped ball is matched with the valve seat. The side of the inner wall of the valve body is provided with a stepped groove, the side of the inner wall of the stepped groove is pressed with a pressure sleeve through the valve seat, and the outer ring of the pressure sleeve is embedded with several springs, One end of several springs is fixedly connected with one side of the inner wall of the stepped groove, and the valve seat is pressed on the other side of the inner wall of the stepped groove through the pressing plate, so that there is no friction transmission between the sealing surfaces of the ball valve and no wear between the valve seat and the sealing surface; The sealing webs are in line contact, which can greatly reduce the sealing torque, reduce the selection cost of the actuator, and enable the ball valve to have a two-way sealing function. The installation is not limited by the flow direction of the medium, and can withstand high pressure and low torque.

进口四偏心球阀characteristic:

The sealing materials are rubber and polytetrafluoroethylene. Due to the limitation of structural characteristics, it is not suitable for high temperature, high pressure, corrosion resistance, abrasion resistance and other harsh working conditions. In industry, high-temperature and high-pressure hard seal valves are mainly gate valves and stop valves. The main disadvantages of these valves are that they are of upper and lower opening structure, the valve itself is heavy, the cost is high, the field installation space is large, and the flow path is relatively large.

进口四偏心球阀Principle:

A four eccentric, spherical and conical sealing two-way pressure ball valve comprises a valve body, a valve seat and a C-shaped ball. The valve seat is fixedly arranged inside the valve body, the C-shaped ball is arranged inside the valve body through the valve rod movement, and the C-shaped ball is matched with the valve seat. One side of the inner wall of the valve body is provided with a step groove, one side of the inner wall of the step groove is pressed with a pressure sleeve through the valve seat, and the outer ring of the pressure sleeve is embedded with several springs, One end of the plurality of springs is fixedly connected with one side of the inner wall of the stepped groove, the valve seat is pressed on the other side of the inner wall of the stepped groove through the pressing plate, and the inner wall of the valve body is installed with a filter assembly.
