Abstract
The utility model discloses a corrugated pipe stop valve. The corrugated pipe stop valve comprises a valve body. A valve seat is installed in the center in the valve body. A valve clack is installed on the valve seat. A valve rod is connected on the valve clack. The valve clack is fixed through a valve clack cover. A valve sleeve is sleeved on the valve rod. A corrugated pipe is embedded between the valve rod and the valve sleeve. Padding is arranged on the corrugated pipe. A padding gland is fixed on the valve sleeve. The valve rod is connected with a drive rod through a guide block. A hand wheel is sleeved on the drive rod which is connected with a drive seat. The drive seat is connected with an upright column in a bolt mode. A sealing gasket is padded between the valve sleeve and the valve body. The corrugated pipe stop valve has the advantages that structure is simple, operation is convenient, production cost and economic losses due to examining and repairing are saved for the chemical industry.
Description
Technical field
