Structure and Working principle
(1) Indication of valve¡¯s open and close position
Ball, stem and handle are one assembly unit. The stem head is a flat-square structure and the valve is easy to be seen either in the open or close position from the handle is in. When the handle or the flat-square of the stem head is parallel with the pipeline , the valve is in the fully open position ; while in the fully close one when vertical to the pipeline.
(2) Locker
To prevent mal-operation of the valve, a hanging lock can be used to lock it when in the fully open or close position, which is very important especially for the valve mounted outside or not allowed to be opened or closed by the technological flow.
(3) Stem fly-proof structure
The stem may be pushed out by the pressure in the middle cavity of the body when the medium goes through the valve. To prevent this, a fly-proof structure is made on the lower part of the stem (Fig.1). In this way, even if the packing and/or thrust bearing are burnt out in a fire or damaged by other cause, the medium¡¯s pressure inside of the body will have both stem flange and upper sealing face of body tightly contacted so as to prevent a lot of medium from leaking from the damaged packing place.
