Abstract

The invention provides a valve rod filler maintenance-free flat gate valve. The valve rod filler maintenance-free flat gate valve comprises a valve body, valve bases, a gate plate, a valve rod, a valve cover, a bracket and a hand wheel; the valve bases are arranged in a cavity of the valve body; the gate plate is arranged between the two valve bases; one end of the valve rod is connected with the gate plate, and the other end of the valve rod is connected with the bracket and the hand wheel through a valve filler chamber, wherein the valve filler chamber is arranged on the bracket. The valve filler chamber is arranged on the bracket, so that the valve cover has no need to be dismounted during maintaining and replacing a filler, and the bracket only needs to be dismounted to replace and maintain the filler.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a maintenance-free slab gate valve with stem packing. Background technique [0002] Packing is a dynamic sealing filling material used to fill the valve packing chamber space to prevent the medium from leaking through the valve stem and the valve packing chamber space. Packing seal is one of the key parts of valve products. In order to achieve a good sealing effect, on the one hand, the material and structure of the packing itself must meet the needs of the medium working conditions; Structural considerations ensure a reliable seal. [0003] In the existing slab gate valve, when maintaining the valve stuffing chamber, the valve cover needs to be opened for maintenance. The whole maintenance process takes a lot of time to disassemble and install the valve, which is very troublesome; and the existing sealing scheme, with the As the service time of the valve increases, its performa...
