COMPLETE SPECIFICATION.
An Improved Stop Valve for Liquids, Vapours, or Gases.
I, THOMAS PHIPPS of 169 Bridge Street, Northampton, Brewer, do hereby
leclare 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 :-
The invention has for its object an improved construction of stop valve whereby
the valve is secured against injury from incrustation, oxidation, or corrosion and the
body of the valve can be readily and quickly attached to pipes running in a straight
line, to pipes at right angles to each other, or to pipes at an intermediate angle
either to the right or left.
In order that my invention may be clearly understood and readily carried into
effect I will proceed aided by the accompanying drawing fully to describe the same.
COMPLETE SPECIFICATION.
An Improved Stop Valve for Liquids, Vapours, or Gases.
I, THOMAS PHIPPS of 169 Bridge Street, Northampton, Brewer, 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 :-
The invention has for its object an improved construction of stop valve whereby
the valve is secured against injury from incrustation, oxidation, or corrosion and the
body of the valve can be readily and quickly attached to pipes running in a straight
line, to pipes at right angles to each other, or to pipes at an intermediate angle
either to the right or left.
In order that my invention may be clearly understood and readily carried into
effect I will proceed aided by the accompanying drawing fully to describe the same.
DESCRIPTION OF THE DRAWING.
Figure 1 is a sectional elevation of my improved valve showing the body thereof
arranged for attachment to pipes running in a straight line.
Figure 2 is an exterior view of the same.
Figure 3, is a face view of one part of the valve body with the valve in position
therein.
Figure 4, is a face view of the other part of the valve body.
Figure 5 is a face view of the valve separately.
Figures 6 and 7 are cross sections drawn at right angles to each other through
the valve and valve seat or diaphragm showing the parts in the position assumed
when the valve is open.
Figures 8 and 9 are similar cross sections to Figures 6 and 7 but showing the
parts in the position assumed when the valve is closed and
Figure 10 is a cross section drawn on a line intermediate of those on which
Figures 6 and 7 and Figures 8 and 9 are drawn and
Figure 11 is a section of a valve constructed according to my invention but of a
slightly modified form.
ab represent the two parts of the body of the valve which are provided with
flanges a 6 which are fixed rigidly together by bolts and nuts c passing through
holes as in such flanges.
d is the valve seat or diaphragm which is lodged in recesses formed in the
flanges a band is held firmly in position between such flanges by the nuts and
bolts c fixing the two flanges together, a suitable packing ring shown by the thick
black lines a³ being placed on each side of the valve seat or diaphragm between it
and the flanges a', b' to secure a tight joint. e is the valve which is formed or
fixed on one end of the stem or spindle e which passes through a stuffing box at on
the part a of the valve body; this stem or spindle e is formed with a screw e' at its
upper part and on its end is fixed the hand wheel by which it is rotated.
دو
The valve seat or diaphragm d and the valve e are formed respectively with flat
bars or "lands" d', see Figures 5 and 10, they are also formed with openings or
passages d on opposite sides of their axis and with recessed webs d³ e inter-
mediate of the said openings or passages and connecting the adjacent bars or
"lands o o Thus when the valve is either fully open or fully closed
the bars or "lands" d'e, which secure the joint between the valve seat or
diaphragm and the valve, cover and protect each other as shown at Figure 10, B0
that in whichever position the valve is left, the liquid, vapour or gas controlled
thereby can have no access to such bars or "lands whilst any, incrustation
corrosion or oxidation of the webs de cannot injure the valve as their surfaces
-

are so far recessed from the bars or "lands and from each other as to prevent
any cutting action on each other or on the bars or "lands" by any incrustation,
corrosion, or oxidation thereon.
The part 6 of the valve body is formed or provided with a fixed stop 63 and the
bottom of the valve is provided with stops e which act in combination with the
stop 6 so that when one or the other of such stops e' is in contact with the stop b³
the valve will be either fully open or fully closed and the bars or "lands" d'e
completely protected.
Nuts mounted on the screw e bear on the gland of the stuffing box a to
compress the packing around the stem or spindle e, to enable the valve to be drawn
tightly to its seat and to permit of adjustment whilst the upper nut acts to lock the
lower one in its adjusted position.
The valve represented at Figures 1 to 10 has the flanges a¹ b¹ made diagonally
of the body thereof and the bolt holes a³, 63 are symmetrically arranged. By these
means I am enabled to arrange the parts a and b in four different positions in
relation to each other without any addition or alteration except the turning of the
valve so as to place the stops e in position to act in combination with the stop b³
enabling the valve to be thereby adapted to lengths of piping in a continuous right
or to pipes at different angles to each other.
If desired however the flanges a¹ b¹ may be made parallel with the centre line of
the body of the valve as represented at Figure 11.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A stop valve constructed substantially as herein shown and described and for
the purpose stated.
2. A stop valve having a removeable valve seat, a disc valve, and recessed webs
connecting the meeting bars or "lands" of both valve and valve seat substantially
as herein shown and described and for the purpose stated.
3. A stop valve having the two parts of the body connected together by flanges,
capable of being fixed together in different relative positions whereby the inlet and
outlet apertures may be arranged in different relative positions substantially as
herein shown and described.
