PRESSURE-GOVERNOR AND REGULATlNG-VALVE.
SPECIFICATION forming part of Letters Patent l. T0.32O,3D2 dated June 16,1885.
Application tiled March 27, 1885. (No model.)
To aZZ 1071,0721 it may concern:
Be it known that L Lnvi SHOOK, of Pitts burg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Pressure-Governors and Regulating-Valves; and I do hereby declare that the followingis a full, clear,and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, andito the letters of reference marked thereon, which form part of this specification.
My invention relates to t1uid-pressure-regulating valves, and to that class in which a dia phragm is used, and in which the valves are balanced with reference to the pressure in any position.
The object of my invention is to produce a pressure-regulating valve that will be sensitive to theleast variation in the pressure ofthe fluid, in which the valves will not stick when closed, and in which the valve-stem guides are protected from the governed fluid passing through the regulator.
The figure of drawing shows a vertical section of my invention.
A is the shell, provided with the inletB and outlet (3. The inlet and outlet have the partition D between them,whieh is provided with two circular openings, that are controlled by the double or puppet valve F F. The seatsE E for this valve are plain surfaces upon the partition. The valve is formed of two disks, and may be in one piece or two,as I have shown them. The seat of the valve (1, or the part that comes in contact with the seat E, is sharp, or formed into what is called a knifeedge seat. These seats being of equal diameter and occupying no space upon the seats E E, it will be seen that the valve will be balanced to the pressure on the inlet or outlet side of the same.
A stem, S, provided with a collar, 0, passes through the valve, and the latter is held upon the same by the nut f.
Upon the lower part of the shell is a cap, K, having a cup or recess, H, formed in it and in line with the valve-stem. About midway of the cup guides hi1arcfmrmedtbr the lower end of the valvestem.
Through the bottom of the cup is inserted a screw, 1, which is directly below the valvestem. By operating the screw the valve may be adjusted to regulate the amount of fluid allowed to pass or closed entirely. This screw is provided with a jam-nut, l, for holding itin position when set.
The cup is tilled with mercury or glyeerine, to protect this guide h from the action of the fluid passing through the valve, thereby pre venting the stem from sticking by corrosion or any gummy substance.
To the upper part of the shell is attached the diaphragm-chamber L,which is composed ofan upper and a lower part, and between which is held a flexible diaphragm, M.
Where the stem passes through the diaphragm,washers N O are provided,onc on each side of the diaphragm,the washer on the lower side being smaller than that on the upper, the object being to allow for a free movement upward and a limited movement downward, but sul'lieient to give a free opening to the valve.
The diaphragm is fastened to the stem by a nut, b, that clamps the washers against the shoulder (Z on the stem.
To the top 01. the chamber L is secured a springehamber, Q, and into the end of this chamber is screwed a hollow bolt, It, that serves to guide the upper part of the valve-stcm,and alsoto adjust thetension of the spring P, which is placed between the bolt and the diaphragm, the tendency of the spring being to keep the valves open.
The operation is as follows: Steam,water, or gas passing in at B flows by the valve until a pressure is reached to which the spring is set, when the back-pressure, acting upon the diaphragm, overcomes the tension of the spring, and closes or partly closes the valve, thus regulating the supply to the demand at the predetermined pressure.
Having dcscri bed my i nvention, what I claim is 1. In a fluid-pressure regulator, the combination of the stem,the two disk-valves formed with knileedges, the diaphragm, the washers on. each side thereof, and the spring bearing on the upper of said washers with a tendency to keep the valve normally open, and the tubular ICO 4. In a fluid-pressure regulator, the combination of the double knife-edge valve, the [5 valve-stem, the lower fluid-protected guide for the stem, with the diaphragm and the springadjusting and valve-stem guide-bolt, substantially as and for the purpose set forth.
In testimony that I claim the foregoing as my 20 own I affix my signature in presence of two witnesses.
LEVI SHOOK.
