Description

A kind of High Temperature High Pressure forged steel safety check
Technical field
The utility model relates to valve field, is specifically related to a kind of High Temperature High Pressure forged steel safety check.
Background technique
Along with the development of modern industry, power station industry is also able to develop rapidly, and the requirement of the valve needed for the industry of power station also improves further, shows that temperature that valve uses, pressure requirements are higher.High Temperature High Pressure forged steel safety check belongs to a kind of automatic valve, its Main Function be prevent medium flow backwards, prevent pump and drive motor reversion, and the releasing of vessel media, adopt solid forging, be applicable to very much high temperature and high pressure condition to use, and there is resistance coefficient greatly in existing High Temperature High Pressure forged steel safety check, the problems such as wear-resisting, high temperature resistant, decay resistance is not good.
Summary of the invention
In order to solve the deficiencies in the prior art, of the present utility modelly provide a kind of High Temperature High Pressure forged steel safety check.
The technical solution that the utility model adopts is: a kind of High Temperature High Pressure forged steel safety check, comprise valve body and valve seat, inner chamber and lumen is comprised in described valve body, flashboard is connected with in described inner chamber, be provided with pressure self-sealing structure in described lumen, described pressure self-sealing structure comprises selfsealings seat and Sealing, and described Sealing is arranged on middle cavity wall, described selfsealings seat and Sealing extruding coordinate, and described selfsealings seat is also provided with sheave.
Also be provided with link between described inner chamber and flashboard, described link one end is fixedly connected with flashboard, and the other end is hinged on interior cavity wall.
Described flashboard and the end face of valve seat are sealed and matched firmly.
Described sheave is bolted on selfsealings seat.
The sealing surface of described flashboard and the end face of valve seat adopts the built-up welding of Si Taili cobalt base hard alloy to form.
Described valve body adopts solid forging to make.
Described valve body two ends are also provided with connecting groove.
The beneficial effects of the utility model are: the utility model provides a kind of High Temperature High Pressure forged steel safety check, pressure self-sealing structure is adopted at valve body lumen, chamber pressure is higher, sealing effect is better, flange or the adapter of different length can be welded in valve body two ends, adapt to different adapter requirements, valve plate aperture is large, resistance coefficient is little, in use effectively can solve the problem because structure causes resistance coefficient large, the sealing surface of valve plate and valve seat adopts the built-up welding of Si Taili cobalt base hard alloy to form, sealing hardness is high, wear-resisting, high temperature resistant, corrosion-resistant, antifraying property is good, long service life.
Accompanying drawing explanation
