W. A. PRAT VALVE Filed 001:. 11. 1922 Sept 29,
Patented Sept. 29, 1925.
UNITED STATES WILLIAM A. PRATT, 0F BAYONNE, NEW JERSEY.
VALVE.
Application filed October 11, 1922.
To all whom it may concern:
Be it known that I, \VILLIAM A. PRATT, a citizen of the United States, and a resident of Bayonne, in the county of Hudso and State of New Jersey, have invented a new and Improved Valve, of which the following is a full, clear, and exact description.
The present invention relates to new and useful improvements in valves, and it pertains more particularly to valves for controlling the flow of water in water systems.
It is one of the primary objects of the present invention to provide a valve which will automatically operate to supply a predetermined volume of water.
It is a further object of the invention to construct a valve of this kind so that the valve member thereof will seat without hammering.
It is a further object of the invention to construct the valve so that after the same has been opened and a predetermined volume of water has been discharged therethrough, the valve will operate to automatically close and cut off the flow of water.
It is a still further object of the invention to construct a valve in such a manner that a slight depression of the plunger starts the automatic operation of the valve.
Vith the above and other objects in view, reference is had to the accompanying drawings, in which Figure 1 is a longitudinal sectional view of a valve constructed in accordance with the present invention, the valve being shown in its normal closed position;
Fig. 2 is a longitudinal sectional view of the valve after operation has been started;
Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2;
Fig. 1- is a transverse sectional view taken on the line 44 of Fig. 2, and
Fig. 5 is a transverse sectional view taken on the line 5-5 of Fig. 2.
Referring more particularly to the drawings, the valve comprises an elongated housing 1.0, and such elongated housing is provided with a lower discharge end 11, an inlet extension 12, and an open. screw-threaded upper end 15. Adjacent the lower end of the housing 10 and between the inlet 12 and the outlet 11 thereof, a partition 14; is provided, and such partition is formed with a tubular passage 15 extending therethrough. The housing 10 is formed on one of its sides with an enlarged portion 16, and extending Serial No. 593,858.
through said enlarged portion 16 is a bypass passage 17 provided with an open end 18 located within the inlet 12. The upper end 19 of this by-pass passage is right-angular in form and extends into the housing 10, as indicated at 20. Passing through the enlarged portion 16 of the housing 10, is an overflow passage 21, the lower end 22 of which is positioned below the partition 14 so that this passage will discharge below the valve in a manner to be hereinafter described. The upper end of this passage is right-angular in form and extends into the housing as indicated by the reference character 23.
The reference character 24 represents a plug, and said plug has screw-threaded engagement with the threaded end 13 of the housing, as shown. This plug 24 has a passage 25 therethrough, in which is mounted a plunger 26, the upper end of which is pro vided with an operating knob 27. This passage 25 terminates in an enlarged chamber 28, the lower end of which is formed with a valve seat 52. This chamber 28 terminates in a still larger chamber 29, and said chamber 29 terminates in a still larger screwthreaded recess 30. The lower end of the plunger 26 is screw-threaded, as at 31, and having threaded engagement therewith is a plug 32, the upper face of which is'cut out to provide a seat for a valve member 33, which valve member is adapted to engage the seat 52 heretofore mentioned. 2
Having screw-threaded engagement with the walls of the screw-threaded recess 30, is a plug 34, and such plug is provided with a centrally-arranged passage 35. This plug 34 serves to secure a strainer 36 in position between itself and the shoulder formed at the base of the chamber 29, and said plug is further provided with a passage 37 extending therethrough. Extending-through the enlarged portion 16 of the housing and into the passage 37, there is a valve member 88, which valve member is screw-threaded as at 39 and has a tapered end 40 adapted to enter the passage 37 to restrict the flow of fluid therethrough for a purpose to be hereinafter described.
The reference character 41 designates a valve member which is slidab ly mounted in the passage 1.5 of the partition 14, and said valve member is provided with an angular end Projecting from the valve member 42, is'a screw-threaded extension 4 1', and said llt) estension has screw-threaded engagement with a socket formed in the member 46. Mounted on the valve member 41, is a piston head 47, and said head carries a packing 48, adapted to engage the inner walls of the housing 10. The member 46 heretofore mentioned is formed with a flat member 4-9, and said flat member 49 serves to secure a packing 50 in place, which packing is opposed to the packing 48 heretofore mentioned. Projecting from the flat member 49, is a stem 51., and said stem 51 slides through the opening in the plug 34.
As will 'beclearly seen from Fig. 3, the plug 24 is cut away as indicated by the reference character 60, and it is into this cut-- out portion of the plug 24 and a portion of the chamber 28 that the overflow passage 21 heretofore mentioned extends.
The device operates as follows:
With the parts in the position shown in Fig. 1, the fluid in the inlet passes upwardly through the by-pass. passage 17 into the chamber 29, through the passage 37 in the plug 34 tothe piston head 47 to seat the valve. At the same time, the pressure of the fluid in the inlet 12 is: carried upwardly on the piston formed by the packing 48, and thus the entire valve and its mechanism is forced to maintain the valve in closed position.
Assuming now that the plunger 26 be depressed: Upon depressing the plunger 26, the valve member 33 moves out of engagement with the seat 52, and owing to the cutout portion in the plug 24, the member 32 displaces the fluid in the chamber 29 and forces the same through the overflow passage 21. Immediately the member 32 is depressed, the end 20of the by-pass passage i7 is closed, and thus the pressure of the fluid in the inlet 12 is no longer present upon the piston 47. As this condition takes place, the pressure of the fluid in the inlet 12 acting on the piston formed by the packing 48, serves to force said piston upwardly, the fluid in the chamber between the piston 47 and. the plug 34 passing outwardly through the passage 87 through thecut-out portion of the plug 24 and to the overflow passage 21. This posit-ion of the parts permits of the piston 47 raising until the upper end of its stem 51 engages the. lower end of the plunger 26. as shown in Fig. 2. In this position, the valve is partially open, as shown in Fig. 2. As the valve continues to open, the member 32 is forced upwardly into engagement with the seat 52, thus cutting off the overflow passage 21, and again opening the end 20 of the by-pass passage 17, and permitting the fluid under pressure in the inlet 12 to again enter the chamber 29. The fluid now passes through the passage 37, where it again engages the piston 47 and serves to force the same downwardly to cause the valve 41 to again seat and shut off the flow of fluid through the discharge.
By adjusting the valve member 38 which extends into the passage 37, it is obvious that the speed at which the fluid passes through said passage 37 may be regulated, and thus the speed of operation of opening and closing of the valve may be determined, and by determining the speed at which the valve opens and closes, the volume of fluid passing through the discharge opening 11 of the valve may be regulated.
From the foregoing, it is apparent that the present invention provides a valve in which only the depression of the plunger 26 to cut off the pressure of the inlet from the rear side of thepiston 47 is necessary to setup an automatic operation, and that as soon as the opening of the valve is completed, the valve will automatically return to closed position. Furthermore, by constructing the valve 41 with an angular face 42, it will be noted that the flow of fluid through the pasi sage 15 is not abruptly cut off but is gradually reduced until the valve member 43 seats, by which construction a seating of the valve without hammering or pounding is had.
