Abstract
The invention discloses a kind of corrosion-resistant high-pressure stop valve, including valve body, valve seat, flap, valve gap, valve rod, handwheel；Valve gap cross section is c-type, and including upper end body, lower end body, lower end body is arranged on valve body, is provided with shaft seal structure between lower end body and valve rod outer wall；Being provided with the first lining in the body of upper end, the first liner outer wall coordinates with interporal lacuna in the body of upper end, and endoporus is connected with valve rod threaded upper ends；Handwheel and the first lining stretch out the fixing connection in upper end of body upper surface, upper end；Valve body inner bore hole wall is provided with anti-corrosion layer；Improvements further: be provided with the second lining between Ti Nei hole, upper end and the first liner outer wall；It is provided with end face lining between body upper surface, upper end and handwheel lower surface.The present invention is corrosion-resistant, wear-resisting, and service life is long.
Description
Technical field
The present invention relates to a kind of valve, particularly to a kind of stop valve.
Background technology
Stop valve is suitable as cutting off or regulating and throttling use, when being applied in corrosive fluid transmission pipeline network, and corrosion resistant
Erosion property is poor, and service life is short.
Summary of the invention
The present invention is to solve the deficiencies in the prior art, it is provided that a kind of good corrosion resistance, service life length
Corrosion-resistant high-pressure stop valve.
The present invention is achieved through the following technical solutions technical goal.
Corrosion-resistant high-pressure stop valve, including valve body, valve seat, flap, valve gap, valve rod, handwheel；Described valve gap cross section is c-type,
Including upper end body, lower end body, lower end body is arranged on valve body, is provided with shaft seal structure between lower end body and valve rod outer wall；On described
Being provided with the first lining in end body, the first liner outer wall coordinates with interporal lacuna in the body of upper end, and endoporus is connected with valve rod threaded upper ends；Institute
State handwheel and the first lining stretches out that the upper end of body upper surface, upper end is fixing to be connected；It thes improvement is that: described valve body inner bore hole
Wall is provided with anti-corrosion layer.
In said structure, between Ti Nei hole, described upper end and the first liner outer wall, it is provided with the second lining.
In said structure, between body upper surface, described upper end and handwheel lower surface, it is provided with end face lining.
Use technique scheme so that present invention have the advantage that
1, valve body inner bore hole wall is provided with anti-corrosion layer, significantly improves corrosion resistance of the present invention, significantly extends present invention service life.
2, being provided with the second lining between upper end Ti Nei hole and the first liner outer wall, when the first lining rotates, the first lining is not
Directly abrasion Ti Nei hole, upper end, extends present invention service life further.
3, being provided with end face lining between upper end body upper surface and handwheel lower surface, the most directly wear and tear during hand wheel rotating upper end body
Upper surface, extends present invention service life further.
