Abstract
The invention discloses a cutting ferrule stop valve. The cutting ferrule stop valve comprises a valve body, a valve deck, a valve rod, a valve seat and a valve element. A valve cavity is formed in the center inside the valve body. The valve deck is fixed to the top end of the valve seat. The valve rod penetrates through the valve deck. The bottom end of the valve rod is fixed to the valve element and extends into the valve cavity. The top end of the valve rod is connected with a hand wheel and extends out of the valve body. A first streaming channel and a second streaming channel are formed in the two sides of the valve cavity respectively. The first streaming channel is horizontally arranged. The second streaming channel is arranged in an inclined mode, wherein the included angle alpha between the second streaming channel and the vertical wall of the bottom of the valve cavity is 75 degrees. A spacer is arranged between the valve rod and the valve seat. A seal ring is arranged at the joint of the valve seat and the valve body. Cutting ferrules are arranged on a medium outlet and a medium inlet respectively, wherein the medium inlet and the medium outlet are formed in the two ends of the stop valve. By the adoption of different structural designs of two different channels, the second streaming channel is arranged in the inclined mode, and fluid resistance is reduced; the cutting ferrules are arranged at the medium inlet and the medium outlet, so that stability of connection between the valve body and a medium pipeline is improved; the spacer is arranged between the valve rod and the valve seat, the seal ring is arranged at the joint between the valve seat and the valve body, and therefore sealing performance is improved.
