Abstract
The utility model relates to a high-temperature resistant and high-pressure resistant triple eccentric sealing butterfly valve, which comprises a valve body, a valve seat, a valve stem, a disc and a valve stem driving device, wherein the valve stem is fixedly connected with the valve body in the axial direction and is rotatably connected with the valve body in the radial direction, and the valve stem is fixedly connected with the disc; the valve stem and the disc have certain eccentric quantity, and a sealing ring of the disc is of a partial cone structure; and a sealing surface of the valve seat is sprayed with stellite alloy, and the sealing ring of the disc is made of stainless steel. The utility model has the beneficial effects of high-temperature resistance, high-pressure resistance and long service life.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of high temperature high voltage resistant three eccentric sealed butterfly valves.
Background technique
With the comparatively approaching prior art of the utility model the patent No. being arranged is ZL200620072829.3, name is called the utility model patent of " three eccentric two-way pressure butterfly valve ", comprise valve gap, valve body, valve seat, valve rod, butterfly plate and valve rod driving device, valve rod is connected with the valve body axial restraint, radially be rotationally connected, valve rod is fixedlyed connected with butterfly plate, axially and radially there are certain offset in valve rod and butterfly plate, the sealing surface of described butterfly plate is the oblique cone oval structure, and said structure is commonly called as " three eccentric butterfly valve ".The valve body of prior art and the sealing pair of butterfly plate employing metal pair rubber or rubber are to the soft sealing structure form of rubber, and this structure has limited the Applicable temperature and the pressure of butterfly valve widely.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of three eccentric sealed butterfly valves of high temperature resistant, high pressure resistant, long service life are provided.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: high temperature high voltage resistant three eccentric sealed butterfly valves, comprise valve body, valve seat, valve rod, butterfly plate and valve rod driving device, valve rod is connected with the valve body axial restraint, radially be rotationally connected, valve rod is fixedlyed connected with butterfly plate, and valve rod and butterfly plate are inclined to one side cone structure axially and radially having certain offset, the seal ring of butterfly plate, the sealing surface spraying stellite of described valve seat, the seal ring of butterfly plate is made by stainless steel.
The beneficial effects of the utility model: because the sealing surface of described valve seat spraying stellite, the seal ring of butterfly plate is made by stainless steel.Thereby has an advantage high temperature resistant, high pressure resistant, long service life.
