Definitions

  • the control valve has a loose valve plug which is spring pressed towards its seat and is ar- 1 ranged to shut off the water flow as well as throttle the flow through the flush valve.
  • the control valve therefore serves three purposes; as a shutoff valve, as a check valve to prevent back flow, and as a throttle valve, all in a single unit.
  • flush valves for, water closets or urinals are equipped with vacuum breakers on the discharge side of the flush valve to prevent back siphonage of, the contents of the, water closet into the potable. water supply line in the event a vacuum condition c cursin, the system. There is, however, another back flow conditionwhich must be anticipated in such aplumbing system. For example, in a rnu ltistory building there are usually numbers of flush valves and associated control valves on each floor, all connected toa common water supply pipe.
  • one of the flush valves must flrst' be tumedoffuat the associatedmontrol valve until the pressure in themainsupply.
  • trol valveof the present invention is provided with a valve plug.
  • FIG. 1 isa partial, cross section .view of a typical flush valve.
  • FIG. 2 is an enlarged cross-sectional view of the control valve shown in its closedposition; while FIG. 3 shows a modified form of the control valve.
  • the flush valve indicated at 5 is the wellknown ROYAL" Flush Valve of the Sloan Valve Company and is connected to the associated control valve indicated at 6 by the usual tailpiece 1.
  • the flush valve 5 has its outlet tube 8 leading into a plumbingfi'xture such as a water closet or urinal (not shown).
  • the outlet tube 8 also, includes a vacuum breaker 9 to prevent back siphonage which may be of the type disclosed in US. Pat. No. 3,334,646, issuedAug. 8, 1967,
  • the flush valve 5 also includes the usual flexible operating diaphragm 10.nonnally closedupon the main seat 11, and a relief valve 12;, closing upon the relief valve seat 13.
  • the relief valve 12 hasa'stem 14 adapted to be contacted by the plunger 15 of theoperating handle 16 to tilt the head of the relief valve 12 off its seat and permit the pressure in the upper pressure chamber. 17 of the flush valve to be exhausted downward through the barrel I8 of the valve into the outlet tube 8.
  • the inlet water flow. nowraises the diaphragm l0 and water flows downwardaround the outside 30 ofthe barrel 18' into the flush tube and theninto the plumbing fixture flushing the same.
  • the brass body 20 is provided with the threaded inlet connection' ll for the water supply pipe. and 'theoutlet con nection22, attached to thepipe connection 7"of the flush valve 5;.
  • the .valve bonnet-23 screwsinto the-valve body 20 opposite the inlet 2land carries the operating parts of the valve.
  • A'cup shaped wheel handle 241s mounted on top of the..bonnet 23" andis secured byascrewJS-to the top end of threaded adjusting-screw. 26.
  • the threaded screw 26 is in threaded engagement with the.
  • TheiO- ring29 seals ,off the interior of thevalve body 20 from the top portion.
  • the guide sleeve 28* has a flanged portion32 clamped between the bonnet 23 and ,the top-ofthe valve body20 fonholdingit in place.
  • a collar 33 aroundthe threaded screw 26' serves as a bearingland is clamped between the guide sleeve 28* and bonnet 23.
  • a series-of interfitting slots 35 andl'lugs 36" whichi areso constructed ,that they permit vertical adjustmentof the valve stem 27', but not rotaryadjustment; thereby rendering .the.valve operating handlei24 and screw-265nonrising.
  • the controlcvalve hasawalve plug 4fl arranged-in the valve body in opposition to its valve seat 41 and is'providedwith a hollow shank'portion42 within which the lower end-ofvalv'estem 27. projects; This shankportion42 is slidable upon the valve stem for a distance within the space 43 formed between the bottom endof the valve stem 27 and the bottom of the hollow shank 42.
  • a compression spring 44 surrounds the shank 42 and valve stem 27 and extends between the rear side 45 of the valve plug and a flange 46 on the valve stem 27 which flange also contains the O-ring 29.
  • the valve plug 40 is loosely slidable upon the valve stem 27 and is normally urged into seating engagement with the valve seat 41 by spring 44 whenever there is either no pressure, less pressure, or a balanced pressure, on the inlet side 21, or pressures are balanced on both sides of the valve plug. In the closed position of the valve plug 40 it serves as an automatic back check to prevent reverse fluid flow.
  • the wheel handle 24 may be turned so that the end of the valve stem 27 contacts the bottom of the hollow shank 42 forcing the valve plug 40 into seating position and pennanently shutting off water flow. This is desirable in cases where it is necessary to repair the flush valve 5.
  • the counter bore 47 around the valve seat 41 assists in quieting the water flow at higher flow rates.
  • the valve plug 40 has an outer rubber seating surface 50 to provide better sealing qualities and also assists in reducing sound levels.
  • valve plug 40 will be held closed upon its seat 41 by spring 44, as shown in FIG. 2, thereby preventing back flow and trapping the water between the control valve and the flush valve to maintain the pressure in the upper chamber 17 of the flush valve and hold the flush valve closed.
  • the valve plug 40 remains seated and normal conditions are reestablished.
  • valve plug 40 remains seated until the flush valve is operated whereupon it is opened by the inlet pressure and the pressure drop at the flush valve.
  • the flush valve has not been forced open and no flooding condition can occur in the manner previously pointed out.
  • the space 43 is vented by the passage 48 extending through the valve plug.
  • control valve has been generally designed to quiet the water flow it has been found that the use of a wheel handle operating means 24, such as shown in FIGS. 1 and 2, is conducive to some undesirable noise conditions. This is because the wheel handle is cup or bell-shaped, and being entirely supported by screw 25 to the valve body 20, acts as a resonator when high water pressures are flowing through the control valve. By the insertion of a cup-shaped washer 49 under the wheel handle 24 and on top of the bonnet 23, the bell-like noise is suppressed.
  • This washer 49 is preferably made of some suitable spongelike plastic or rubber material and does not interfere with the turning of the wheel handle 24.
  • FIG. 3 illustrates a control valve having a screw driver adjusting means instead of a wheel handle.
  • the threaded screw 26 is provided with a screw driver slot 51 and a protective cup-shaped cap 52 is threaded to the bonnet 23 as shown at 53.
  • the valve plug 40 has its shank portion 42 provided with a relatively loose fit indicated at 54 around the valve stem 27. This loose fit permits escape of fluid from the pocket 43 and also enables the valve plug to better center itself upon its valve seat 41 when operated.
  • valve parts are constructed of plastic materials for purposes explained in the aforesaid US. Pat. No. 3,327,992 and other details of the present application not specifically described, may be had by reference to this prior patent.
