DISCHARGE REGULATORS FOR HYDRAULIC PLANTS Filed NOV. 5, 1954 2 Sheets-Sheet 2 United States Patent English Electric Company Limited, London, England, a British company Application November 5, 1954, Serial No. 467,184
Claims priority, application Great Britain November 13, 1953 4 Claims. (Cl. 137613) The invention relates to discharge regulators by means of which large quantities of water, often under considerable pressure, can be discharged from hydraulic plants with exact quantitative regulation of the water and effective dissipation of its energy. In many cases, it is desirable to fit a discharge regulator with an isolating valve so as to be able to attend to the packings on the discharge valve, and for inspection. However, such an isolating valve, which must have an inner diameter at least as large or larger than the discharge regulator, is very bulky and expensive, and in most cases is difficult to fit in, quite apart from its bulk and costs.
According to the present invention a cylindrical balanced discharge regulator is provided on its upstream side with a shutter device, e. g. a number of radial butterfly valves which in the open position are in alignment with radial ribs arranged upstream of them in a regulator inlet pipe, and when turned approximately 90 about their radial axes contact one another and seal off the regulator inlet pipe.
on a regulating ring surrounding the discharge regulator tube. 6
They may be turned one at a time by means of a large spanner or other portable device operated manually, hydraulically or electrically.
In order that the invention may be clearly understood and readily carried into efiect, two embodiments thereof will now be described by way of example with reference to the accompanying drawings in which: 7
Fig. 1 is a longitudinal section of a cylindrical balanced discharge regulator having an isolating device with internal operating gear, and
Fig. 2 is a longitudinal section of a cylindrical balanced discharge regulator having an isolating device with external operating gear.
The conical regulator inlet pipe 1 is connected by means of radial ribs 2 to a hollow central extension 3 of the inner cone 4, the latter being connected in the usual manner by radial ribs 5 to the cylindrical regulator tube 6, on which slides the tubular slide valve member 7.
A number of butterfly valves 8, say eight, are pivoted and sealed at their inner ends in the said central extension 3, and at their outer ends in the flange connecting the cylindrical regulator tube 6 to the conical inlet pipe 1. The tips and rootsof the butterfly valves 8 and the adjacent faces are part spherical.
In the embodiment according to Fig. 1, inside the said 2,742,055 Patented Apr. 17, 1956 open end of the inner cone 5 for example by means of a hand crank 11 or by means of any suitable gearing or driving mechanism.
By turning the control member 10 about its longitudinal axis, all the butterfly valves 8 are turned approximately about their radial axes from the open position (as shown) in which they are in alignment with the ribs 2 and protected by them from detritus carried by the water discharged, into a closed position in which they contact one another and seal off the regulator tube 6.
In the embodiment according to Fig. 2 the internal gearing inside of the central extension 3 and of the inner cone 4'is omitted, and gear pinion segments 12 are keyed to extensions of the outer pinions of the butterfly valves 8. These gear pinion segments 12 are in mesh with a bevel gear crown 13 forming a regulator ring surrounding the flanges which connect the conical inlet tube 1 and the cylindrical regulator tube 6. This regulator ring has for example one or two lugs 14 which are linked by connecting rods to a servo-motor or other suitable driving mechanism.
When turning the bevel gear crown 13 by means of these lugs 14 a small angle about the longitudinal axis of the discharge regulator, the butterfly valves 8 are turned approximately 90 about their radial axes from the open position shown into a closed position, substantially in the same manner as described with reference to Fig. 1.
While I have herein described and illustrated in the accompanying drawing what may be considered a typical and particularly useful embodiment of my said invention, I wish it to be understood that I do not limit myself to the particular details and dimensions described and illustrated, for obvious modifications will occur to a person skilled in the art.
What I claim as my invention and desire to secure by Letters Patent is:
1. A discharge regulator comprising in combination: an inlet pipe, a cylindrical regulator tube joining the said inlet pipe downstream, an inner cone tapering towards the said inlet pipe and fixedly attached to the said cylindrical regulator tube, a tubular slide valve slidably arranged around the said cylindrical regulator tube controlling the gap between the free end of the said cylindrical regulator tube and the circumference of the base of said inner cone, a central extension of the said inner cone, radial ribs fixedly connecting the said central extension to the said inlet pipe, and a plurality of butterfly valves pivoted each about a radial axis both in the said central extension and in the said regulator tube upstream of the said ribs, the said butterfly valves in the open position being in alignment with the said ribs, and in the closed position contacting one another and isolating the said cylindrical regulator tube from the said inlet pipe.
2. A discharge regulator as claimed in claim 1, wherein the said butterfly valves have projections extending radially inward into and sealed in the said central extension of the inner cone, and comprising a central driving shaft mounted in the said inner cone and central extension there-' ly outward through the said regulator tube and sealed therein, and adjustment means mounted on the said projections and adapted to turn the said butterfly valves about their axes.
4. A discharge regulator as claimed in claim 3, wherein the said adjustment means mounted on the said projections of the said butterfly valves have bevel toothing, and comprising in addition a bevel gear crown mounted rotatably coaxially to the said inlet pipe and cylindrical regulator tube and meshing with the said bevel toothing 10 2,580,384
of the said butterfly valves, turning all of themsimultaneously about their radial axes when being turned about its own axis.
