8` Claims.
(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757).
Objects of the invention are, first, to provide,
novel means of closing the container so as to retain the gas therein and at the same time provide a protective seal to prevent leakage, second, to provide a means of quickly discharging the gas through the discharge orifice for the purpose intendedsuch as for extinguishing fires or inflating flotation equipment; and, third,to provide a means of safely discharging or venting the gas at excessive pressures due to high temperatures,
etc.
With the above and other objects in view, the Iinvention resides in the novel construction, ar-
rangement, and combination of parts hereinafter described in detail with reference to the accompanying drawing, wherein:
Figure 1 is a -view in vertical elevation` of a valve assembly constructed and applied in accordance with the invention.
Figure 2 is a vertical longitudinal sectionon line 2-2 of Figure l with the valve in closed and latched position.
Figure 3 is a sectional view similar to Figure 2 but with the valve in opened and unlatched position.
Figure 4 is a composite detail view of certain valve parts..
This device comprises al chambered valve body I provided with a threaded lowered portion 2 by means of which it is screwed into the neck 3 )of a gas container 4. Threaded portion 2 has a central bore or gas passage 5 in communication withv a central valve body chamber 6 and a raised valve seat 'I is formed in the bottom of the valve chamber and around the inner end of the passage 5. A lateral extension 8 on one side of the valve body serves as a combined fillingnd discharge nozzle and has a through passage 9 leading di` rectly to the valve chamber '6. The valve body chamber 6' and the valve body passages 5 and 9 constitute a iluid conduit by means of which the CO2 or other compressed gas is conducted to' and from the container in the filling and discharging of the latter. Nozzle 8 is screw-threaded externally and internally and a plug. or nozzle tting, I0 is screwed into the discharge orifice of the nozzle. Plug Il) has a central bore or passage and a hemspherical outer head or cap provided with four diametrically opposed openings or parts Il.
Flow of gas through the fluid conduit is regulated and controlled by a valve including sealing means adapted in the closed position of valve to be rmly engaged with the valve seat I and to seal the passage 5. The sealing means is composed of an annular gasket I2 of phenol composition or other suitable material and a blow-out safety disk` I3 of thin frangible material designed to rupture at a predetermined maximum pressure. The disk and gasket are carried by a valveplugor plunger I4 and are mounted in the bottom end of i the plug which, as shown, is recessed and shouldered to seat the disk and gasket therein; the if' disk being on the top side of the gasket so thatv the latter contacts directly with the valve seat when the valve is closed: The lower end of rim of the recessed part of the valve plug I4 is turned in and over the edge of gasket I2 to retain the 2 seal within the recess of the plug.
vThe valve plug I4 is so assembled with the valve body that an appreciable part of its lower portion lies within the valve chamber 6; the plug being movable inwardly and outwardly of the valve chamber through a central opening or orice in the top wall I5 of the chamber. Leakage between the valve plug and the valve body is prevented by means of a short tubular piece of packing IIS,
preferably leather, which lines the central opening or orice with its upper end ilanged over upon the upper surface of the chamber wall I5 and its remaining portion depending well yinto the valveA chamber 6 and snugly embracing the valve plug so as to provide both a valve plug packing and a valve plug guide. The packing I6 is removably anchored to its seat by means of a threaded retainer or washer -Il which is screwed down tight within the internally screw-threaded and recessed upper portion I8 of the valve body. Disposed within the recessed upper portion I8 of thev valve body is a valve plug carrier or support. consisting of a short tubular member or sleeve I9 having a screw-threaded bore and a shoulder or ange 20 at its upper end by 4meansh 45 -of which it is supported upon the upper coil of a helical spring 2 I, the latter encircling'the sleeve in the manner shown with its bottom coil resting y upon the packing retainer washer I'I. The valve plug carrier is-enclosed within the recessed upper end oi' the valve body by means of a cap 22 screwed on the body portion I8 and holding the carrier under a slight compression so that the upward thrust of the spring tends to maintain the sleeve up against the underside of the top of the cap. A cone point headless set screw 23 threaded in the body part i8 and seating in a recess 24 in the cap 22 prevents the latter from turning relative to the body.
The valve plug I4 is screwed into the bore of the carrier sleeve I 9 and moves up and down with the sleeve in which it is positioned so as to place the seal I2-i3 in engagement with the valve seat in the down position of the valve-plug carrier and to hold Athe seal raised above the valve seat in the elevated position of the valveplug carrier. By reason of itsv screw-threaded connection with the carrier-sleeve, the plug I4 can be adjusted manually with respect to the valve-plug carrier to position the seal on or off the valve seat independently of whether the valve-plug carrier is in either lowered or elevated position. To provide for manual adjustment of the valve, the valve plug i4 has a handle-stem portion 25 which projects upwardly through a central orifice 26 in the valve body cap 22 and carries a handle 21 at its upper end.
The valve is adapted to be held down upon the valve seat by a readily releasable latch mechanism including a lever or yoke 28 disposed to lic across the top face of the valve body cap 22 and over apertures or slots 29 in the cap. The yoke 28 is pivoted at one end by a pivot pin 30 engaged in the pivot lugs 3| and 32 respectively formed on the cap 22 and the yoke 28. The yoke is raised and lowered with respect to the cap by means of a latch bar 33 and the latch bar pull-handle 34, the latter being pivotally connected at 35 to the lower end of the latch bar. The latch bar 33 has its upper end pivotally connected as at 36, to the free or lifting end of the lever or yoke 28 and depends downwardly along one side of the valve body, being adapted to be swung into or away from the body for engaging or disengaging the latch lug 31 of the latch bar with respect to a latch lug shoulder or keeper 38, on the side of the valve cap 22.
In the released position of the latch mechanism, the yoke 28 is supported in upwardly raised position above the cap 22 by lugs 39 mounted on the valve carrier sleeve I9 and projecting upwardly through the openings 29 inthe cap when the sleeve is thrust up against the underside of the cap. -In the absence of any superior downward force or pressure on the valve-plug carrier the upward thrust of the spring 2 I is sufficient to maintain the parts yin elevation. As shown in Figure 3, in the released position of the latch mechanism the seal I2-I3 is elevated above the valve seat so that passage of gas into or out of the container is permitted through the passages 5 and 9 and the intermediate connecting chamber 6. To close the passage. the latch handle 34 is pulled downwardly to lower the yoke 28 upon the cap and to cause the valve plug and valve plug carrier to be moved downwardly as the lugs 39 are forced inwardly of the cap by the downward movement of the yoke. When the valve is seated, as illustrated in Figure 2j the -latch is engaged with the latch shoulder or keeper 33 to hold the parts in the down or latched safety wire 42 is inserted through the aligned apertures of the lugs 40 andI latch bar portion 4I and normally retains the latch bar in operative or latching position. When the latch bar handle is pulled outwardly, as when intentionally releasing the valve, the wire is readily fractured or broken.
The valve plug I4 and seal members I2 and I3 also consitute a pressure relief or blow-off means for automatically venting or discharging the container when the gas confined therein attains a predetermined maximum pressure. As is well known, the pressure in CO2 and other gas containers may become dangerous and excessive due to high temperatures unless adequately relieved and to this end, the valve plug I4 has a longitudinal bore, or vent passage, 43 opening inwardly of the lower or recessed end of the plug and terminating within the upper portion of the valve plug stem 25, the latter having pressure escape ports 44 leading from the vent passage 43 to the outside of the stem. The disk I3 seals the plug vent passage 43 and hence prevents any gas escaping through the vent when the valve is opened for filling or .discharging the container. When the valve is closed, the sealing disk and gasket effectively prevents the gas in the container from passing into either the chamber 3.
or'the vent 43, but when the gas pressure attains a predetermined maximum, the disk I3 is adapted to rupture and to thereby permit the gas to pass from the passage 5 of the valve body into the vent passage 43 of the plug, and from whence it escapes to the atmosphere through the ports 44.
In the operation of the device, when an empty cylinder equipped with the fixture is to be lled or charged, the valve is latched in the down or closed position and tied with standard safety wire, as shown in Fig. 2. The valve plug is then unseated and raised to its uppermost position by turning the handle 21. The cylinder is then charged to its required capacity by a filling hose or pipe connected to, and delivering the charge through, the passage 9. When the charging has been completed, the valve is closed by screwing the valve plug down to its seat in the same manner. as closing an ordinary screw valve. The valve is now ready for operation. To release the gas, it is only necessary to exert a slight pull on the latch handle 34, releasing the latch. With the latch in the released position, the pressure of the gas against the disk I3 and the upward thrust of spring 2I, causes the plug to lift and unseat the disk I3 and gasket I2, thereby providing free passage of the gas from the' container to the discharge nozzle 3 of the valve xture. If, after release of the valve. it is desired to temporarily shut off the flow of gas, the valve may be closed by turning the valve handle so as to screw the valve down to its seat.
