3 Claims. (Cl. 137-267) This invention relates to a valve and more particularly to a twin body valve particularly designed for use with respect to tank trucks commonly used in the petroleum industry for the delivery of what are known as white products and brown products. Such tank trucks are commonly built with a plurality of compartments. It is common practice to deliver an entire truckload'of either white or brown products. White products include gasoline while brown products include diesel fuel, kerosene etc. Mixing or contamination of the two products must be avoided or reduced to a minimum. It is also common practice to load a tank truck with two compartments of white products and two compartments of brown products.

It has been determined that a meter for such products which has been calibrated and sealed for the delivery of a white product will not accurately measure the delivery of a brown product and vice versa. Accordingly, it is desirable to provide means upon the various compartments of a tank truck by which its contents may be diverted to one meter for white products and to another meter for brown products. It is also desirable that any contamination or commingling of the two products be avoided or reduced to a minimum.

It is accordingly one object of the present invention to provide a valve for the above-mentioned use.

It is a further object of this invention to provide such a valve by which the contents of a compartment can be selectively diverted to either of two meters.

It is a further object of this invention to provide a valve of the type described wherein the bodies of the valve are so positioned as to completely drain not only the tank being drained but the valve itself so as to prevent contamination of the product when the tank is later used for the transportation of a diiierent product.

It is a further object of this invention to provide means for making adjustments to compensate for misalignment of valves attached to separate tank compartments when connecting piping between such valves to provide a straight-through passage.

It is a further object of this invention to provide such a valve having means associated with each diverting valve for connecting the various compartments in series for a straight-through passage of all of the liquids contained therein.

These and other objects, features and advantages of the present invention will be readily apparent from the annexed specification, in which:

Figure l is a top view of a valve embodying the present invention.

Figure 2 is a section taken along the line 2-2 of Figure l.

Figure 3 is a section taken along the line 3-3 of Figure 2.

Figure 4 is an enlarged fragmentary section taken along the line 4 4 of Figure 2.

Figure 5 is an elevation of a tank truck showing the rates Patent "ice connection of a series of valves attached to the several compartments therein.

Figure 6 is a top plan view of Figure 5.

Referring now more particularly to the drawings, the valve is illustrated as comprising a body 10 including a pair of chambers 11 and 12 disposed at an angle as indicated. Between the two chambers 11 and 12 there is a chamber A having a V-shaped cross section as shown, at the edges of which there is provided a flange 13 providing bolt holes 14 and an inlet port 15. The flange 13 and bolt holes 14 provide means for attaching the valve to the underside of a tank with the port 15 registering with the opening in the bottom of the tank. Each of the chambers 11 and 12 is similar and each is provided with a wall 16 provided with a tlange 17 which is tapped to receive the studs 18 by means of which the ilange 19 with a cap 26 is bolted thereto. Each of the chambers 11 and 12 is provided with an inwardly turned ange 21 which provides a circular opening 22 into the V-shaped chamber A and provides a valve seat 23. A plurality of centering lugs 24 are positioned adjacent the edge of the opening 22.

The wall 16 is provided with opposed ports 25 and 26 machined to a spherical inner surface to receive spherical ball iittings formed on the outside of piping, which piping is retained by iianges also machined to a spherical inner surface and attached to the valve body. Ring seals 27 are provided to prevent leakage. A valve stem 28 extends through each cap 20 and is threadedly received therein in the conventional manner, which valve stem carries at its inner end a nut 29 by means of which a plate 3d clamps a rubber gasket 31 and a rubber sealing ring 32 to a plate 33. The plate 33 is seated against the shoulder 34 formed by a reduced portion of the valve stem 28 and is provided with an annular groove 35 for receipt of the ring 32 and with an annular boss 36 for positioning a coil spring 37 which is provided having one end bearing against the plate 33 and the other end bearing against the inner end of the cap 20. As most clearly indicated in Figure 4, the rings 32 seat against the valve seat 23 when the valve is closed, being centered thereto by the centering lugs 24.

Figs. 5 and 6 illustrate the application of the abovedescribed valve with the outlets 39 in the bottoms of the several compartments 40, of a tank 41 of a tank truck 42, the compartments being defined by partitions 43 and end walls 44. The valves 10 may be attached to the bottoms of the several compartments by aligning the nlet port 15 of a valve with the outlet 39 in the tank and bolting the liange 13 to the area of the tank surrounding the outlet 39. Piping, comprising two parallel lines 45 and 46, interconnect the aligned wall ports 25 and 26 of the several valves, the pipe sections forming the lines having end llanges adapted for attachment with ilanges on the wall 16 surrounding the ports 25 and 26. The rear ends of the pipe lines 45 and 46 may include conventional meters and screw threaded, valve controlled, discharges for connection with a flexible hose.

It will be noted that the chambers 11 and 12 are disposed at an angle. Assuming the valve above-described to have been attached to a tank truck by bolting the iiange 13 over the opening in the bottom of the truck and suitable piping valves and meters to be attached to the openings 25 and 26, as described above, it will be apparent that by opening the valve contained in the chamber 11 while the valve contained in the chamber 12 is left closed, liquid in the tank truck will be drained through the chamber 11 and to the desired meter. Likewise, if the valve contained in the chamber 11 is closed and the valve contained in chamber 12 is open, the product contained in the tank truck may be diverted to a different meter. In order to avoid the necessity of a plurality of meters of the same type where a number of compartments of the truck are to be used to carry the same product, there is provided the two discharge openings 25 and 26 in each of the chambers 11 and 12. In this manner, all of the compartments containing the same product may be connected in series to be passed to the appropriate meter. It will also be apparent that as each of the chambers 11 and 12 is disposed at an angle, the iluid contained therein will be drained and any uid contained in the chamber A will be drained out through whichever of the valves is open so that upon refilling of the tank truck compartment with a dlterent product, contamination is avoided or reduced to a minimum.

While there has been described what is at present considered the preferred embodiment of the invention, it will be understood that various changes and alterations may be made therein without departing from the essence of the invention and it is intended to cover herein all such changes and alterations as come within the true scope and spirit of the annexed claims.
