The closing principle of the stop valve is that the valve clack sealing surface is tightly attached to the valve seat sealing surface by means of the valve lever pressure, so that medium circulation is prevented.
The stop valve has the structural characteristics of self, is required by the flowing direction of a medium, is usually low in and high out, but under the condition of using a high pressure and a large caliber, the cost of an enterprise is greatly increased due to overlarge operation moment, and the waste of materials and resources is caused. The utility model provides an improved structure, which omits a secondary valve clack, simplifies the structure and improves the assembly efficiency.
