Specification of Letters Patent.
Patented Apr. 23, 1912.
Application filed June 19, 1901. Serial No. 65,202.
To all whom it may concern Be it known that I, l/VILLIAM H. SMYTH. citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Valves, and I do hereby declare the following to be a full, clear, and exact description of the same.
This invention relates to a new type of self-acting device for controlling the flow of fluids.
The object of all fluid controlling devices of the character of self-acting valves is to permit freely, the flow of the fluid in one direction and to prevent its return. This object is accomplished by no type of check valve at present in use with the exception of the present invention hereinafter described, as in all such types of valves a portion of the fluid which has passed through the valve returns during the closing of the valve. This slippage in practice is a large percentage of all the fluid which passes through the valve. Another difliculty in valves is the restriction and obstruction they offer to the flow of fluid by the diversion of the currents passing through them.
The object of the present invention is to provide a self-acting valve permitting no slippage or return of fluid which has passed through the valve and which will permit of the flow of the fluids therethrough in straight lines. This object is accomplished by the invention herein disclosed which thus presents a complete departure from all heretofore existing devices both in construction and in the law of operation and is the picneer in a new and generic type in fluid controlling devices.
Described generally the invention consists of means adapted to store up in a part of the valve, a small portion of the power resident in the moving fluid (heretofore expended in diverting the current while passing through valves of ordinary construction) and arranging the device that this stored up power shall be given out again when the forward current ceases, in such a manner as to add forward motion to the current during the closing of the valve. In other words, to constitutethe valve an impelling device as well as a controlling device for the fluid.
More particularly described, the illustrated form of the invention consists of a valve seat rotatable by the current of the moving fluid and provided with helical vanes or other suitable devices adapted by their rotation to cause a forward motion in the fluid in which they are immersed during the closing time of the valve and after the normal current of the fluid has ceased.
Referring to the accompanying drawings for a more detailed description of the form illustrated herein,Figure 1 is a plan view, portions being broken away to more clearly illustrate it. Fig. 2 is a side elevation, portions being broken away to more clearly illustrate it.
1 is a pipe or other suitable container in which it is desired to control the fluid passing therethrough.
2 is a circular, rotatable or flying valve seat provided with one or more apertures 3. In the present form it is shown as ha ing four such apertures. Each of the apertures is provided with a valve or gate 4 adapted to open and close it. This gate 4 in the present instance is loosely hinged on one of its radial sides. The valve seat is also provided with wings or vanes 5 secured thereto and set at an angle to act as runners or impellers of the fluid when rotated, in the nature of a screw pump. The multiple seat 2 is also provided with suitable antifriction devices shown as wheels 6 about its periphery, adapted to bear against a projecting rim or flange 7 in pipe 1. The valve seat is rotatably secured within the pipe by a water-tight joint shown in Fig. 2 as oint 8 between the pipe 1 and valve carrying seat 2. Owing to the angularity of the open gates the seat 2 is put into rapid rotation by the current passing through the valve when in operation. This is facilitated by the antifriction devices 6. Thus the fluid instead of being deflected by the angular gates, passes through in straight lines, the gates, so to speak, continually running away from the impinging current. The valve seat consequently attains a high'velocity of rotation. lVhen the forward motionof the fluid, due to the impulse given it by the pump piston or other cause, ceases, the rotation of the valve seat still continues for some appreciable time owing to its inertia. The vanes or wings during this time give out the power previously stored up and cause a further forward motion of the fluid, acting, in fact, as a rotary pump, thereby inducing more fluid to pass through the valves than is due directly to the action of the normal impelling cause and tending to cause a vacuum beneath the valve. The rotation of the valve seat also tends to close the gates 4 by centrifugal action and the impact of the fluid against that portion of their upper surface which projects beyond the vanes This exposed portion of the gates may be much or little as the circumstances of the case warrant or in proportion to the speed of the fluid to be controlled. Thus the gates will be closed before the seat has wholly ceased its rotation and consequently before its impelling effect on the fluid has wholly ceased so that no slip or return of the fluid which has once passed through the valve can take place. Thus it is seen. that the power heretofore uselessly expended in the diversion of the current through the valve is, by means of the arrangement heretofore described, and illustrated in the drawings, usefully expended in impelling the fluid forward.
Of course the number and arrangement of the gates or their method of attachment and likewise the number, form or position of the wings or vanes are not of the essence of this invention and may be varied to suit the varied conditions or necessities of practice. The same is true with reference to the antifriction wheels which may be replaced by ball-bearing or a central point or journal hearing or even omitted entirely. In brief as the present invention discloses a new idea of end to be accomplished, namely, the utilization of power now wasted by valves and also a new idea of means,the devices illustrated,for the accomplishment of this new end and is consequently a pioneer invention, I do not desire to be confined to the particular form of the invention herein described and shown but desire to claim the invention broadly unrestricted to any particular form, proportion or arrangement of its parts.
