How To Ensure Safety Of Reverse Sealing Of 1 Piece Threaded Ball Valve

This bidirectional metal floating, hard-sealed ball valve comprises a valve body, a valve stem, a ball, an upstream valve seat, and a downstream valve seat. The valve body has an inlet and an outlet, which are interconnected. A disc spring is installed on the end face of the upstream valve seat, closest to the inlet, and positioned between the upstream valve seat and the valve body. A sealing plate is located within the valve body, with a predetermined distance between the sealing plate and the upstream valve seat. This product provides a hard-sealed floating ball valve that achieves bidirectional sealing, reducing costs and simplifying operation. Furthermore, while ensuring a flow-direction seal, this product can also achieve reverse sealing, meeting both high-pressure and low-pressure sealing requirements. The sealing plate effectively ensures the reliability of the reverse sealing.

1 Piece Threaded Ball Valve consists of a valve body, ball, seat, shaft, and guide sleeve. Its unique feature is that the ball utilizes a fixed support structure, a boss is located on the seat where it contacts the ball, and a lip seal is installed on the sealing surface between the seat and the ball. A seal is also installed on the shaft adjacent to the guide sleeve. This product's technical solution addresses issues such as unreliable sealing, easy shedding of the hardened layer on the sealing surface, and high torque in ball valves used in the GSP process for pulverized coal transportation. It also addresses the issue of easily damaged guide elements, improves the valve's resistance to abnormal jamming, and eliminates the need for dedicated gas lines for purging.
