1 Claim.
This invention is an anti-syphoning, diaphragm type, ball cock or valve.
An object of the invention is to provide a simple, substantial, practicable, compact, low cost manufacture and labor installation, copious flowing, and fool-proof ball cock.
A further purpose is to provide a diaphragm type shutter or closure member and valve assembly free from delicate parts and yet which is highly sensitive to the influence of induction flow toward the supply pipe; that is a valve which is safely anti-syphoning.
Further an intent of the invention is to provide for the instant adjustment of the flow capacity of the valve as may be desired.
The invention resides in certain advancements in this artball cocksas set forth in the ensuing disclosure and having, with the above, additional objects and advantages as hereinafter developed, and whose constructions, combinations, and details, and manner of operation will be made manifest in the following description of the herewith illustrative embodiment; it being understood that modifications, variations, adaptations and equivalents may be resorted to within the scope, spirit and principles of the invention as it is claimed in conclusion hereof.
Figure 1 is a stem end elevation of the valve unit. Figure 2 is an elevational side view of the assembly. Figure 3 is an axial section valve body shell and valve insides.
The valve body includes a substantial shell 2 having an elbow inlet duct 3 ending in an axially disposed nipple 4 surrounded by an annular water discharge compartment 5 having a lateral outlet boss 6, Fig. 1. A water supply pipe 1 attaches to the inlet duct 3, and a stand pipe 8 attaches to the outlet 6.
One side of the chamber 5 is closed by a firm rubber or the like packer 9 flexed in a crown over the circular rim of the nipple 4 and the back margin of the packer rests in a sealin position on an outwardly facing, internal shoulder or seat I l which is on a transverse plane somewhat rearward of the rim of the nipple. The packer has a plurality of holes I 0 about the nipple and leading to the discharge chamber 5, and also has a central port l2 to which the nipple discharges.
superposed on the central, convex or outer face of the packer 9 is a coextensive, firm rubber, or the like, closure member or diaphragm l5 which is imperforate and at its rim fits the bore of the shell 2 and tends to constantly close the central port [2 of the packer 9 which forms a tight washer on the shoulder I I.
The packer and the diaphragm are firmly clinched in the shell by a rim-threaded bushing I6 screwing into the outer open end of the shell and pressing against the near margin of the diaphragm. This diaphragm normally bears on the crowned center of the packer 9. The diaphragm has a positive pressure or bias pressure on the rim of the nipple to normally close it and prevent back flow of water to the nipple and from the chamber 5 should a vacuum generate in the supply nipple. Reversely, if the diaphragm is free the water pressure in the nipple, in normal operation, will bulge the diaphragm outward and water can flow to the openings l0 and to the discharge chamber 5.
Means are provided whereby to positively and automatically press the diaphragm to its closing position on the cooperative packer and here includes a ram l9 having external threads 2!! cperative in a complementary bore of the bushing or gland Hi. The ram has an outwardly projecting stem [Be on which is fixed a float lever 2| whereby the screw ram is motivated. An antifriction, presser button 22 is shiftably and rotatively mounted in the inner end of the ram and is adjustably pressed toward the diaphragm [5 by a jack screw 23 threaded axially in the stem of the ram.
If so desired a spacer ring 25 may be interposed between the facing margins of the discharge diaphragm and the discal packer 9 thereby affording a more open passage to the outlet openings l0.
When the float lever 2| tends to move the ram outward from the packer water pressure in the nipple instantly acts to bulge the diaphragm outward and discharge of water is set up in the valve outlet.
The crowned, basal packer has two noticeable advantages; its central port allows the water to discharge from the nipple 4 whilst the packer is very firmly seated on the lip or rim of the nipple and this, therefore, is not subjected to wire-cutting as occurs when the water course is across the nipple lip. Second, the usual tendency of the passing water to whistle is wholly avoided, and the flow is substantially soundless in the valve.
What is claimed is:
An anti-syphoning valve device of the class set forth having a casing including a discharge compartment, a coaxial, water inlet nipple in said compartment and an annular outwardly facing seat on the bore of the compartment shell wall and concentric with and axially rearward of the rim of said nipple, a crowned, discal rubber packer flexed over and constantly seated on the nipple rim and lodged at its perimeter on said seat, 'said packer having a central port within the nipple rim: and having other openings communicating to the discharge compartment, a transverse flexible valve diaphragm normally centrally seating on the crown of said packeri and closing said port to a coaxial gland screwed into one end of the shell and engaging the adjacent margin of the diaphragm and a ring interposed between the diaphragm and the packer for clinching said packer and the margin of the dia- 7 4 phragm firmly in place against said seat in the shell, a float actuated presser screw movable axially in said gland for forceably closing the diaphragm against said packer and, reversely for releasing it to permit water flow from the nipple and said port to the discharge chamber, via said openings.
