Abstract
The utility model relates to a two-piece internally threaded ball valve which comprises valve seats, a valve body, a ball body, a valve rod and a handle. A flow-out channel and a flow-in channel are arranged in the valve body. A valve cavity is formed between the flow-out channel and the flow-in channel. One end, adjacent to the flow-in channel and one end, adjacent to the flow-out channel of the valve cavity are respectively provided with a valve seat. The ball body is arranged between the valve seats. A valve rod hole is formed in the valve body. The valve rod penetrates through the valve rod hole. One end of the valve rod is connected with a flat notch in the ball body in a plugging mode to form circumferential positioning connection. The other end of the valve rod is provided with the handle. The valve seats are made of teflon or teflon glass fibers. Sealing faces sealed with the ball body are arranged on the valve seats to form flexible sealing. The two-piece internally threaded ball valve has the advantages of being capable of preventing fire and leaking, convenient to replace and the like.
