Description

Oct. 10, 1933. T. P. NEWMAN ET Al.l 1,930,060
STREAM REGULATOR FiIed Oct. 15, 1930 diaphragm l0 and force the valve stein 15 toward its closed' position against the action oi spring 21. When the pressure on the inlet side of the valve drops; the bach pressure will drop accordingly and spring 21 will function to lower the stem 15 and thus increase the opening through the ports 13 and lll so as to obtain the same new at the lower pressure.
It has been iound that the valve as previously described, does not iiutter appreciably but taires a position substantially immediately accordance with the adjustment oi spring 21 and the pressure of the` incoming fluid. Any sudden increase in inlet pressure will cause a corresponding increase of pressure against the diaphragm 10, thereby tending to close the valve against the action of the spring 2l.
Referring particularly to Fig. 'i there is illus trated a typical fountain installation in which the regulating valve would be subjected to intermittent use. In this illustrated application the regulating valve is shown having its outlet 3 connected to a drinking fountain 26 and its inlet connected to a shut-ofi valve 27, the latter being connected to any suitable source oi supply 28.
In an installation of this character, the valve functions substantially as previously described, that is, if the user operates valve 27 slowly valve l5 will not be moved approximately from the position shown in Fig. 2 and will accordingly permit flow of water through the valve. Should valve 27 be opened too Iar or suddenly or should the supply line pressure suddenly increase, the sudden flow of water through the regulating valve would act upon the diaphragm 10 to move the valve stem toward its upper position thereby maintaining a substantially constant :dow through the regulating valve.
From the above it can be seen that there is provided a stream regulating valve which may be used for either continuous or intermittent service and which when used in drinking fountain service will tend to prevent sudden spurts orgusts oi water from the fountain.
Installation of such a stream regulator will also insure a flow at constant pressure even though the supply pressure is temporarily reduced due to abnormal use on the same line or increased due to a raising of the pressure during the occurrence or a re either of which two conditions frequently occur in certain communities. In other words, the stream regulator valve will permit the use of a drinking ountain on a serv- `ice where the pressure may vary through a reasonable range.
It is obvious that minor changes may be made in the above invention Without departing from the spirit and scope or the invention as deilned in the claims appended hei-em.
We claim:
l. A regulating valve comprising a valve body provided with an inlet and outlet of substantially equal cross sectional areas, a hollow partition separating said inlet and outlet, a shank member extending through the walls of said partition and being provided with ports leadinginto said hol- 10W partition and additional ports leading to the outlet side oi said valve, a piston valve slidable in said shanlr and arranged to control the openings through said ports to control the flow of fluid through said valve, said valve permitting restricted flow therethrough when in closed position, a spring lor normally urging said piston valve open and .a diaphragm operatively connected to said piston valve, said diaphragm being subject to the pressure in the outlet side of the valve.
2. A regulating valve comprising a valve body divided into a high pressure chamber having an inlet and a. low pressure chamber having an outlet, a shank member'enlarged at its upper end to receive a 'Iiexible diaphragm and having a cylindrical projecting portion formed with vertically aligned ports therein, a ilexible diaphragm in the enlarged portion oi said shank. said diaphragm being subject to the pressure in the outlet side of the valve, a bonnet secured to the enlarged end of said shank to secure said dia,- phragm therein, a piston stem having spaced annular portions slidably mounted within said cylindrical portion and arranged to control the opening through said ports and being secured at its upper end to said diaphragm, a spring for normally urging said valve stem in open position and an adjusting screw for varying the tension on said spring, said valve being arranged to permit restricted flow therethrough when in closed position.
