' Feb. 5, 1946.
Filed July '7. 1944 Patented Feb. 5, 1946 UNITED STATES PATENT OFFICE MIXING TANK Otto Thiel, Detroit, Mich.
Application July 7, 1944, Serial No. 543,841
1 Claim.
This application relates to mixing tanks and more particularly to a check valve construction thereof, shown in the appended drawing whose Figure 1 is a top plan view and whose Figure 2-is a section on line 2-2 of Figure 1.
The drawing shows a mixing tank I having its upper end closed by a head I i having lines I2, I3, and I5 connected to it.
The head is formed as a casting with three separate bosses for the various lines, the boss 20 for the water inlet line I2, the boss 2| for the gas inlet line I3, and the boss 22 for the mixture outlet line I5. The bosses 20 and 2l are connected respectively by transverse bores 23 and 24 to check valves which are disposed directly in the head. The boss 22 opens directly to the inside of the head, that is the underside.
Figure 2 shows the head casting II which has a boss 25 into which opens a water outlet line 21. The bore 23 is shown as opening into the inside of a well 28 formed integral with the head casting.
Disposed in well 23 is a check valve construction which as shown includes a cover casting 30 with which is integral a sleeve 3|, insidek which is one of two closing plugs 32. The upper ends of these closing plugs are spherical and circular in cross section and contour and the lower ends are conical to form needle valves, the circular andspherical upper ends permitting the lower ends to move slightly off the center line and find their own seats. A sleeve 33 is threaded at its upper end into the lower end of sleeve 3l. A third sleeve 34 has its upper end threaded at 35 into thelower end of sleeve 33. The sleeves 34 and 33 clamp rubber sealing rings 36-31 against the sleeves 33-3I. At 39 is a strainer fixed to sleeve 34.
The entire assembly of the cover casting 30, which carries sleeves 3|, 33, and 34, rings 36 and 31, plugs 32, and strainer 39, forms a unitary assembly which may be dropped into the well 28 and is accessible merely by loosening a few cap screws 43 accessible at the top of the head.
'Ihe cover casting 3i) has a transverse bore 44 which connects the interior of the valve to the line 21. f
The flow path for water is as follows:
It comes into the tank through line I2, boss 20, bore 23, and it enters the well 28 and goes down around the lower sleeve 34 and enters that lower sleeve 34, moving upwardly at the arrow 45, going through the strainer 33, and past the lower end of the lower plug 32 and then up past the lower end of the upper plug # 32 and then into the bore 44 of the casting 30 and then down through the outlet line 21, to the bottom of the tank.
Now having described the check valve construction herein shown, reference should be had to the claim which follows.
I claim:
A mixing tank having a tank head to which is connectedan inlet fluid line, and a check valve construction within the head, the check valve construction being a unitary structure removably disposed within the head, and removable from or applicable to the head as a unit, without requiring removal or disturbance of the head or the line connected to it, the head having an integral, depending, open top, closed bottom well into which the inlet line opens, and the check valve construction comprising a cover for the well, the cover having as part thereof a depending sleeve dipping into the well, said sleeve being open at its top and bottom, the cover having a bore opening to a surface thereof and thus to the tank interior and also opening to the upper end of the sleeve, and a gravity check valve plug within the sleeve for closing it against down flow into the well from the cover bore, the plug being held in the sleeve by restrictions at its upper and lower ends, the valve responding for closing to pressure in the tank exceeding that of the inlet line.
OTI'O THIEL.
