Abstract
The utility model relates to a stop valve, in particular to a stop valve consisting of a valve body 1, a valve bonnet 2, a valve rod 3, a hand wheel 4, a valve rod sealing member 5, a valve spool 6 and a valve seat 7. The valve bonnet 2 is arranged on the valve body 1. The hand wheel 4 is arranged on the valve rod 3 to increase the rotating torque of the valve rod 3. The valve rod 3 is arranged on the valve bonnet 2 and obtains axial thrust by the valve bonnet. The sealing member 5 is arranged between the valve bonnet 2 and the valve rod 3 to prevent the material from flowing out from the valve bonnet 2 and the valve rod 3. The valve spool 6 is arranged at one end of the valve rod 3. The valve seat 7 is arranged on the valve body 1. The sealing surface of the valve spool 6 is closely matched with the sealing surface of the valve seat 7 to prevent the material from flowing from one chamber of the valve body to the other chamber so as to achieve the closure function. The center of the sealing surface of the valve spool 6 has a certain offset distance from the center of the sealing surface of the valve seat 7. When the sealing surface of the valve spool 6 is close to the sealing surface of the valve seat 7, the sealing surface of the valve spool 6 rotates or swings relative to the sealing surface of the valve seat 7 so that the sealing surface of the valve spool 6 slides towards the outside of the sealing surface relative to the sealing surface of the valve seat 7 to clean the attachments on the sealing surface of the valve spool 6 and the sealing surface of the valve seat 7. In order to increase the cleaning strength, a spring 8 is arranged between the valve rod 3 and the valve spool 6.
