The invention relates to the technical field of
petroleum transportation, in particular to a
petroleum pump valve with a valve rod nut capable of being rapidly disassembled and assembled. The
petroleum pump valve with the valve rod nut capable of being rapidly disassembled and assembled comprises a valve body, a valve
deck is connected to the valve body through an installation
flange, a valve rod is installed on the valve
deck and penetrates through the valve
deck, the lower end of the valve rod extends into the valve body, the bottom of the valve rod is connected with a valve clack used for opening or closing the valve, and the top of the valve rod is connected with a hand wheel through a hand wheel nut; and the petroleum pump valve further comprises a valve rod nut rapid dismounting and mounting
assembly, the valve rod nut rapid dismounting and mounting
assembly is installed on the valve deck and connected with the valve rod. According to the petroleum pump valve with the valve rod nut capable of being rapidly disassembled and assembled, the valve rod extrudes a
silica gel lantern ring, so that lubricating oil is extruded out and adheres and lubricates the valve rod, the situation that the valve rod is not smooth or stuck in the rotating process can be effectively prevented, and then use is facilitated.
