VALVE.
Application led September 16, 1920. Serial No. 410,608.
To all whom, it may concer/n.:
Be it known that I, OYsTEiN JAoonsnN, a citizen of the United States, and a resident of Dayton, in the county of Montgomery and State of Ohio, have made a new and useful Invention in Valves, of which the following is a specification.
The invention relates to check valves and particularly to check valves for use with corrosive liquids requiring what is known as an acid resisting metal or acid resisting iron, although certain features of the valve construction are of general utility and the invention is therefore not limited to a valve made of any particular composition. The invention has for its principal objects the provision of an improved check valve, (l) which is of cheap simple construction and can be cast throughout of an acid reslstlng metal or composition requiring little or no machining; (2) which will open and close slowly thus avoiding any danger of breaklng the valve or injury to the seating surfaces; (3) which has improved means for guidmg and cushioning the valve, and (4) which has a relatively light valve in proportion to its size so that its inertia is reduced to a minimum and the valve made correspondingly responsive to the movement of the liquid passing therethrough. One embodiment of.
the invention is illustrated in the accompanying drawing wherein- The figure is a longitudinal sectlon through the improved valve.
As the valve is primarily designed for use in connection with corrosive liquids it is made of a composition resistant to the action of such liquids such as a high silica iron, one
. of which compositions is known by the trade name of Duriron Such composition is necessarily very hard and brittle and in the design of the valve these properties are taken into consideration. The valve is thusconstructed so that any shocks tending to fracture the metal are reduced to a minimum, and so that practically all machine work, aside from the grinding of the seating\sur faces of the valve and seat is eliminated. `In order to reduce the danger of fracture and to prevent injury to the seating surfaces the inertia of the valve is reduced Aby making it hollow, and the speed of movement reduced by the use of throttlingi or dash pot cylinders which also act as gui es for the upper and lower sides of the valve. These features of construction will be readily understood by an mspection of the drawing.
Referring now to the drawing; 1 is the valve casing preferably of acid resisting iron, such asthe Duriron heretofore referred to, contalnlng a high percentage of silicon; 2 is a screen of similar material at the inlet side o f the valve; 3 is the valve mounted for reclprocatlon inthe casing; 5 is the outlet connection secured to the casing l by means of thebolts 6; and 7 is a guide member for the upper Ilend of the valve with its flange clamped between the outlet pipe and the casghe valve 3 is made in the form of a hollow casing, as indicated in the drawing and 1s relatively li ht, so that it is readily unseated by the 0W of the liquid through the casing, and is provided at its ends with the guide parts 8 and 9 guided in the cylinder or dash pot members 10 and 11. The part 8 has a stop shoulder 12 for limiting the opening movement of the valve adapted to engage the end of the member 9. The ide member 7 is in the form of a spider with arms 13 carrying the member 10 and with the flange 14 lyin between the inlet pipe and the Bange on t e casing. The latter flange is slotted as indicated at 15 to receive the bolts 6 for securing the parts together.
The screenv2 at the inlet side of the valve until it can be moved downward.
The valve 3 seats upon the casing 1 at 18, the surfaces of the two members, being ground alon the contact areas, so that a tight joint 1s secured when the valve is seated. The parts 8 and 9 have a relatively loose sliding fit in the cylinder members 10 and 11, no grinding or machining bein required. Fluid can thus enter the mem ers and escape along the parts 8 and 9, but such action is relatively slow insuring a retarded movement of the valve. In order to prevent too great retardation in the closing movement, the member 11 which is carried by the webs 19 is provided with the port 20.
The retarded movement of the valve vin o eningand closing is not only of Ageneral a vantage in that the seating area of the valve is protected from in'ury due to a too vigorous seating of the va ve at a metal to metal contact, but is of garticular advantage where a brittle aci resisting metal such as Duriron? is re uired, in that such a metal is easil fracture The use of dash pots permits t e making of the valverelatively large and massive, giving a large opening and a free passage of liquid and at the same time removes the objection of undue inertia and jarring which would ordinarily apply where a large valve is used.
In the opening movement of the valve the retarding eilect is due to the action of both of the dash pot constructions, as the air or liquid must be expelled from the upper one and li uid drawn into the lower one Abefore the va ve is fully opened. The valve is also retarded in closing, as liquid must be drawn into the upper cylinder 10 and expelled from the lower one 11 before the valve can seat,v
and the throttling of the flow in passing between the loosely fitting` members l() and 8 and 11 and 9 and through the part 20 insures a movement of such slowness that the valve seats with a very slight impact, the force of which is minimized by the hollow valve construction.

What li claim is: l
1. lln combination in a check valve construction, a casing, a valve in the casing pro# vided with guide extensions on its o posite sides, and guide receptacles carried y the casing and receiving said extensions, restricted outlet means for the receptacles to the interior of the casing being provided to throttle the inflow and outflow of luid and retard the movements of the valve, the said extensions and receptacles having metal to metal contact.
2. In combination in a check valve construction, a casing, a valve 'in the casing provided on opposite sides with cylindrical guide extensions, and a pair of guide cylinders for the extensions carried by the casing and having closures for their outer ends, the said extensions fitting loosely in the cylinders with a metal to metal contact whereby a flow of liquid to and from the cylinders along the extensions may occur and the cylinders act as retarding means for the valve.
In testimony whereof, I have hereunto subscribed my name this 10 day of September, 1920.l
