Improvements in Valves for Steam, Water, Acids, or the like.

Improvements in Valves for Steam, Water, Acids, or the like.
I, ERNEST RICHARD FARNSWORTII, of Lumsdale, near Matlock, in the County of
Derby, Bleacher, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in valves such as are used for con-
trolling the flow of liquids or fluids and especially to valves used for steam or
water or for acids or acid solutions, the object being the provision of a valve with
a removable plug formed of a material that will resist the destroying action of
acids or the like.
In carrying out my invention I construct the body of the valve in any suitable
way and of any suitable material, but preferably so form it that it has at the
centre a conical chamber whose surface forms a seating for the valve proper and
at the same time has leading to it both an inlet and outlet port. The valve or
valve plug I preferably form of a shape to correspond to the conical chamber
referred to This plug is really a shell or bush of a metallic alloy that will resist
the destroying effect of acids. It is secured to the valve spindle by a nut or
the like so that it may be readily removed therefrom when worn and be substituted
by another, or be re-faced. The conical chamber is also so arranged that its
surface can be readily re-faced when necessary. The interior of the valve
chamber is so arranged that when the plug is raised a clear passage is left for
the liquids or fluids.

Improvements in Valves for Steam, Water, Acids, or the likė.
I, ERNEST RICHARD FARNSWORTH, of Lunsdale, near Matlock, in the County of
Derby, Bleacher, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement : -
This invention relates to improvements in valves such as are used for con-
trolling the flow of liquids or fluids and especially to valves used for steam or
water or for acids or acid solutions, the object being the provision of a valve with
a removable plug formed of a material that will resist the destroying action of
acids or the like.

page_text: In order that the invention may be thoroughly understood I have appended
hereunto a sheet of drawings showing a plug valve in cross-section with my im-
provements applied.
In carrying out my invention and referring to such drawings I construct the
body of the valve A, in any suitable way and of any suitable material, but
preferably so form it that it has at the centre a conical chamber B, whose
surface forms a seating for the valve proper and at the same time has leading to
it both an inlet port and outlet port. The valve or valve plug C, I preferably
form of a shape to correspond to the conical chamber referred to. This plug is
really a shell or bush of a metallic alloy or soft metal, such as lead or the like,
that will resist the destroying effect of acids. It is secured to the valve spindle D
by a nut E or the like so that it may be readily removed therefrom when worn and
be substituted by another, or be re-faced. The conical chamber is also so arranged
that its surface can be readily re-faced when necessary. The interior of the valve
chamber is so arranged that when the plug is raised a clear passage is left for
the liquids or fluids.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A valve for steam, water acids or the like with a readily removable plug
constructed of a metallic alloy, or soft metal, such as lead or the like, and capable
of resisting the destroying effects of acids or acid solutions.
2. The combination with the spindle of a plug valve, of a readily removable
plug such as C composed of a inetallic alloy or soft metal such as lead, and capable
of resisting the destroying effect of acids or acid solutions.
