INTERNAL STOP MEANS FOR VALVES Filed April 25, 1960 Awa /m mra/vf Pan 444w,
United States Patent 3,107,546 INTERNAL STOP MEANS FOR VALVES Milton E. Rowland, Long Beach, Qalih, assignor to Pacific Valves inc, Long Beach, Caiih, a corporation of (Zahtornia li iied Apr. 25, 1966, Ser. No. 24,362 2 Claims. (Cl. 74-526) This invention relates to an internal stop means for valves whereby it is insured that the valve stem will be rotated'the proper amount to move the valve from open to closed position.
An object of my invention is to provide an internal stop means for valves where the limiting stop means is entirely within the body of the valve so that it cannot be broken or tampered with.
Another 0 ject of my invention is to provide a novel internal stop means of the character stated, which is particularly adaptable for globe or ball type valves, and which is so constructed md arranged that it may be readily disassembled when repairing the valve or replacing parts thereof.
Still another object of my invention is to provide a novel stop means of the character stated which is simple in construction, inexpensive to manufacture, and which can be easily assembled.
Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.
In the drawing:
FIGURE 1 is an exploded view of the internal stop means and the valve stem.
FIGURE 2 is a fragmentary vertical sectional View of the valve body and valve stem.
FIGURE 3 is a bottom plan view of the stop plate and the stop cam in one position of the parts.
FIGURE 4 is a view similar to FIGURE 3 but showing the parts in another position.
FIGURE 5 is a bottom perspective view of the stop plate.
Referring more particularly to the drawing, the numeral 1 indicates a valve body in which the globe or ball valve is rotatably mounted and which is not shown, since this is usual and well known in the art. A valve stem 2 extends upwardly from the rotatable ball or globe valve, and this stem extends upwardly through the bonnet 3 of the valve. A piston 4, on the stem 2, may fit closely within the bore 5 in the bonnet so that the stern will be accurately guided as it is rotated by the wheel or handle, not shown. In order that the stem 2 may be accurately rotated through an arc of 90 for the purpose of opening or closing the valve, I provide a stop means which consists of a stop member 6 nonrotatably mounted on the stem 2. The stem 2. is flattened on both sides, as shown at 7, and the stop member 6 is formed with a central bore 8 to fit these flat faces. Thus the stop member can be pulled vertically oft of the stem 2 if desired, but it will rotate with the stem at all times. The stop member 6 is formed with two opposite points or projections 9 and 10, the purpose of which will be further described.
A stop plate 11 is removably but nonrotatably mounted on top of the bonnet 3. The bonnet is formed with two opposite notches 12 and the stop plate is provided with two downwardly extending lugs 13 which fit into the notches 12. Thus the stop plate 11 will be removably mounted but nonrotatable on top of the bonnet 3. The central hole 14- in the stop plate permits the stem 2 to pass through it. A pair of stop lugs 15 and 16 project downwardly from the stop plate 11 and are arranged in the same horizontal plane as the stop member 6. The points 9 and to of the stop member are adapted to engage the lugs 15 and 16, as shown in FIGS. 3 and 4, and thus limit the rotation of the stem 2 to an arc of A cap or nut 17 is threaded onto the bonnet 3 and this nut holds the stop plate 11 securely in position, and particularly with the lugs 13 pressed into the recess '12 so that the stop plate wiil be non-rotatably held in proper position.
Having described my invention, I claim:
1. An internal stop means for valves including a valve body, a bonnet on the body, a stem extending through the bonnet and projecting from the same, a stop means for said stem comprising a plate removably and nonrotatably mounted in said bonnet, a projection on said plate, said bonnet having a recess therein to receive the projection and nonrotatably hold said plate in the bonnet, said stem extending through the plate, stop lugs depending from the plate, said stop lugs being positioned one on each side of the stem, a stop member, a flat face on the stem, said stop member having a bore therein tofit said flat face on the stem, said stop member being engageable with the stop lugs on rotation of the stem, said stop member being formed with diametrically opposed tapered points thereon, said tapered points on the member being engageable with said stop lugs.
2. An internal stop means for valves including a valve body, a bonnet on the body, a stem extending through the bonnet and projecting from the same, a stop means for said stem comprising a plate removably and nonrotatably mounted in said bonnet, a projection on said plate, said bonnet having a recess therein to receive the projection and nonrotatably hold said plate in the bonnet, said stem extending through [the plate, stop lugs depending from the plate, said stop lugs being positioned one on each side of the stem, a stop member, a flat face on the stem, said stop member having a bore therein to fit said flat face on the stem, said stop member being engage-able with the stop lugs on rotation of the stem, said stop member being formed with diametrically opposed tapered points thereon, said tapered points on the member being engageable with said stop lugs, a cap threaded on said bonnet and bearing against said plate to hold said plate in position within the bonnet.
