Description
Technical field
The utility model relates to a kind of high temperature modification single-seat valve, belongs to mechanical field.
Background technique
High temperature modification valve in the common modulating valve of existing structure, its deficiency is: at first, the spatial altitude of valve packing letter riding position can not satisfy+650 ℃ requirement, must recomputate; The second, filler layout and lubricated structure can not satisfy+650 ℃ requirement; The 3rd, the matching gap between the outer unit of guide sleeve and spool targeting part can not satisfy+requirement of thermal expansion 650 ℃ the time, can cause the two to burn together.The 4th, when considering+650 ℃, main parts size rationally use material.
Summary of the invention
The purpose of the utility model provides a kind of high temperature modification single-seat valve, to overcome the deficiency of existing technology.
To achieve these goals, the utility model adopts following technological scheme:
A kind of high temperature modification single-seat valve comprises valve body, it is characterized in that, valve body is provided with the valve gap assembly; Be provided with valve seat in the valve body, valve seat is provided with mangetic core assembly, is provided with the guide sleeve seat assembly between mangetic core assembly and the valve body, is provided with dentiform gasket between guide sleeve seat assembly and the valve body; Mangetic core assembly is provided with valve rod, is provided with resilient key in the middle of the valve rod, and the valve rod outside is provided with the valve gap assembly; The valve rod upper end is provided with spacer, and spacer has Packing seat, and two spacers and a Packing seat are divided into two groups to the high temperature filler; The spacer right side is provided with two screw plugs, and valve stem tip is provided with travel indicator, and travel indicator and valve rod contacting part are provided with thin nut; The travel indicator bottom is provided with Gland and hold-down grid, compresses filler by double-screw bolt and nut, realizes sealing purpose
Preferably, three groups of superhigh temperature resistant fillers had both solved the sealing problem of valve rod, had reduced the frictional force of valve rod in the to-and-fro motion process again.
Preferably, filler is the special graphite-filled inconel base alloy powder of high-temperature-resistant flexible, its objective is the heat-resisting quantity that improves device.
Preferably, valve body, valve gap assembly and guide sleeve seat assembly adopt the F321 forged steel of superhigh temperature, its objective is the heat-resisting quantity that improves device.
The utility model in actual use, what solved effectively that former technical products cann't be solved uses problem in the superhigh temperature situation, has obtained good economic benefit and social benefit.
