Knife valve seat with cleaning function

Abstract

The invention discloses a knife valve seat with a cleaning function. The valve seat comprises a base and an outer convex plate. A collecting tank is welded to the lower end of the base, a filter screen is horizontally placed in the middle position of the collecting tank, the outer convex plate is arranged out of the valve body in a sleeving manner, a groove is formed in the middle of the valve body, a sealing pad is mounted in the groove, spray headers are separately mounted on the left and right sides of the groove, the spray headers are fixedly connected to a water pump through rubber pipes,and water outlet holes are separately formed in the left and right sides of the lower end of the valve body. According to the knife valve seat with the cleaning function, by arranging the sealing padin the groove, the sealing effect of the knife valve is enhanced on the one hand, and wear generated by movement of a knife switch up and down is reduced on the other hand, so that the service life is prolonged. The valve seat is more easily cleaned by means of the built-in spray headers. A user needs not to clean the valve personally, and the spray headers can spray at 180 degrees, so that the valve seat is cleaned all around.

Description

technical field [0001] The invention belongs to the technical field of valve seats, and in particular relates to a knife valve seat with a cleaning function. Background technique [0002] The knife valve is one of the most commonly used cut-off valves. It entered my country in the 1980s. In less than 20 years, its use has expanded from the general field to a wider range of industries. The knife valve is the most commonly used One of the cut-off valves, developed from coal preparation, gangue discharge and slag discharge in mining power plants to urban sewage treatment, from general industrial pipelines to professional pipeline systems such as food, sanitation, and medicine, as an opening and closing device to control the flow of media , The fully circular DC channel is designed without slag and jamming. The bottom end of the knife plate is processed into a blade shape, which has the function of cutting off soft materials such as fiber, pulp, and wood pulp, and has a good open...
