CHECK VALVE.
Application filed February mentioned which assures the checking of the return flow.
A further object of the invention is to so design the valve that it seatsunfailingly.
A still further object of the invention is to so construct the valve that it may, through the influence of the passing medium, turn periodically to find a ncwseat, wherebyto Wear evenly and clear the seat of obstructions.
Another object of the invention is to design the housing of the valve on lines to facilitate the passage of the medium in its full capacity. I
A final but nevertheless.important object of theinvention is to constructthe same of few and simple parts, wherebyit may be produced at low cost. V
l/Vith the above objects in View andany others which may suggest themselves in the specification and claim to follow, a better understanding of the invention may be obtained by reference to the accompanying drawing, in
which Figure 1 is an elevation of the novel valve; Fi g. 2 is a longitudinal section'thereof; Fig. 3 is a view taken in the direction ofthe arrow in Figure 2, of the valve with its cap and moving parts removed"; 1
Fig. 4 is a bottom viewof the valve cap; and
big. 5 is a section of the valve stem, showing a bottom vicwof the valve di k.
Referring specifically to the drawing, 10
denotes the horizontal portion of the valve.
housing, which is essentially on the lines of thetypical gate'valve housing, having its ends tapped as shown at 11 to receive the pipe sections between which the valve is inter-' posed. I I
The housing is extended from the portion 10 in an inclined direction to form an upper portion 12 whose outlet is tapped as shown at 13 to receive a cap 14. Thecrownof the cap is polygonal in outline to receive a'wrench when the cap is to bescrewed down or'removed. I 1 i v r The housing is divided by an annular seat 15 for a valve disk 16 the latter being carried by an axial stem 17. That part of the stem foreign matter .16 tl'ie inedium. finds a fullin that the intermr walls of the housing are 17, 1926. Serial to, 88,870.
which extends above the disk receives a coil spring 18 and passes into a be'aring'sleeve medially carried by a crossbar 19 located in and forming a partof the cap 14:. That part of the stem which extends below the valve disk 16 enters a bearing 2O formed by the union of radial wings 21 cast in the housing just belowthe' valve scatlfi. v
As far as the valve has been described, it
will be apparentto those skilled in 't-l e art,
that the medium such as water, air, steam or other fluid obtains passage through the valveby entering the chamber below the disk 16, forcing the latter to open by receding against the tension of the spring 18, and pass ing on in a lateral direction out of the valve.
The wings 21 are set obliquely to the path in which the medium travels, so that the latter is deflected in a lateral direction as it meets the disk 16. The bottom face of the latter is formed with radial ribs 22, and'these being struck by the laterally moving medium cause the disk 16 to turn to some extent as it yields to the pressure of the moving medium.
seat, sothat the latter will wear uniformly; also the lateral or rotary movement of the disk before it seats will tend to dislodge any that may cling to the disk or the seat, keeping thecontacting from becoming coated, pitted or scored, and from sticking and therefore hampering the free action of the valve.
Upon issuing from the sides of the disk :apacity conduit,
curved or bulged out, as shown-at 23, 'to
offer lJllGlilGdl'Lllil. an unrestricted flowi The path of the medium is, it will be noted, practically'straiglit froiu one side of the valve to the other, and no tortuous, sharply curved or otherwise restricted passages are contended with, so that the novel valve offers a minimum resistance to the medium.
In providing the spring 18 to insure the .35 surfaces seating of the valve, an added function is performed, in that the spring also serves to regulate or cont ol the turning tendency of w the valve disk 16, so thatit will not spin or slap. This feature, in limiting the disk to partial rotation, insures a new cont-acteach time the disk seats, and of course makes the operation'of the valve noiseless.
In providing a two-part stemfor the valve disk, and a bearing for each part, the disposal ofthe workingelement of the valve is rendered stable, devoid of strains and unaffected by varying the position of the valve housing. Opemtien of the valve fer long periods Without attention may thus be expected.
