Description

Stop valve with observable valve cover

Technical Field

The utility model relates to the technical field of stop valves, in particular to a stop valve with an observable valve cover.

Background

The stop valve, also called a stop valve, is one of the most widely used valves, and is popular because the friction force between sealing surfaces in the opening and closing process is small, the stop valve is durable, the opening height is small, the manufacture is easy, the maintenance is convenient, and the stop valve is not only suitable for medium and low pressure, but also suitable for high pressure.

Chinese patent grant bulletin number: CN213575616U provides a stop valve, and this patent can prevent that valve gap and valve body from taking place wearing and tearing at the dismantlement in-process through setting up sealed pad between valve gap and valve body to produce the leakage that leads to, set up the valve clack lid on the valve clack and can effectually prevent that the medium from getting into the spread groove that valve rod and valve clack are connected and erodeing the corruption to it, effectually prolonged the life of valve rod and valve clack.

The protection effect is enhanced by arranging the sealing gasket and the valve clack cover, so that the sealing gasket and the valve clack cover are not easy to wear and corrode, but the surfaces of the sealing gasket and the valve clack cover are also easy to wear in the long-term use process, and under the sealing of the stop valve, workers cannot observe the internal condition of the sealing gasket and the valve clack cover from the valve cover easily, so that after the protection performance of the sealing gasket and the valve clack cover is damaged, parts cannot be replaced in time, the protection effect of the valve cover and the valve clack is reduced, and the sealing gasket and the valve clack cover are also easy to wear and corrode, so that the use of the stop valve is influenced.
