What is the life of a high platform ball valve?

There is now a new type of high platform ball valve called a valve body, valve cover, upper valve seat, ball, lower valve seat, valve stem, thrust pad, butterfly spring, anti-loose cover, handle, lock block , bolts, limit rods, nuts, packing sleeves, packing, sealing ring. The whole upper structure has two valve seats in the valve body, the two valve seats are an upper valve seat and a lower valve seat respectively, and the upper valve seat and the lower valve seat are respectively provided with corresponding two sides under the spherical body; the valve stem is sleeved out from the valve body The valve stem is provided with a boss structure, the valve stem of the lower part of the boss is made into a flat head, the flat head of the valve stem is inserted into the groove of the ball body, and is connected with the ball body; the thrust pad of the valve stem is provided with a thrust pad and a thrust pad There are two pieces, two thrust pads are correspondingly arranged to define the boss; the upper part of the valve body is provided with a high step for positioning the actuator, and the high step and the valve body are designed in a joint body. Direct assembly of electric and pneumatic actuators enables remote adjustment and tight shut-off of the media. The utility model has the advantages of simple structure, small volume, good sealing performance and long service life.
Flange high platform ball valve
    The sealing structure of the high-platform ball valve adopts the combined sealing method of the O-ring, the packing and the thrust washer. The seal is directly sealed by the thrust washer at low pressure, and the O-ring and the packing act together at high pressure. Sealing the valve stem; in the present invention, due to the adjustment of the O-ring, whether the pressure is increased or decreased due to constant pressure or instability, the sealing performance can be ensured, thereby greatly prolonging the height. The service life of the platform ball valve.
