Abstract

The invention discloses an integrated stop valve, relating to the field of a valve and comprising a valve body; a valve seat is installed in the center of the valve body; a valve clack is arranged on the valve seat in a matching manner; the upper end of the valve clack is connected with a valve rod; the stop valve is characterized in that a stuffing box is arranged on the valve rod in a penetrating manner; a cavity matched with the lower end of the stuffing box is formed in the center of the upper side of the valve body; the lower end of the stuffing box is arranged in the cavity in the center of the upper side of the valve body in the matching manner and is connected in a sealing manner; a stuffing is arranged in the stuffing box and is compressed by a stuffing box gland; the valve rod above the stuffing box gland is in threaded connection with a nut seat; the nut seat is connected with the valve body by fastening via an upright post; the upper end of the valve rod is connected with a hand wheel. According to the integrated stop valve disclosed by the invention, a valve cover connected with the upper end of the valve body is omitted, no leak point exists and the sealing effect is improved.

Description

technical field [0001] The invention relates to the field of valves, in particular to an integrated stop valve. Background technique [0002] The globe valve used in existing pipelines has many leakage points, and the medium in the pipeline sometimes leaks out, and the service life is short, especially once the toxic medium leaks out, it will cause immeasurable losses. Contents of the invention [0003] The purpose of the present invention is to provide a safe and reliable integrated stop valve with long service life and no leakage point. [0004] The technical solution for achieving the above purpose is: including a valve body, a valve seat is installed in the center of the valve body, a valve disc is arranged on the valve seat, and a valve stem is connected to the upper end of the valve disc; it is characterized in that: There is a stuffing box, the upper center of the valve body is provided with a cavity matching the lower end of the stuffing box, and the lower end of ...
