vulves, of which improvements the followingl is a specification.4
TheV Invention described herein relates to no Vcertain improvements in check or non-return valves for lluids.
The principal source of trouble Iin the employment oi check-valves has been that the valve becomes suddenly seated, striking a sha blow,V which is sometimes sufficient to brea or so injure the valve ,es to prevent its performing its properfunction.
The object o the invention described herein is to provide means for preventing the sud- :o den blow or seating of the valve, 'wlnle not iny vent the return or ac flow of fluids.
3o in ig. 1 means for starting theval-ve from its` erferingwith its ro er movement to pre- 'l`he invention is hereinafter more fully described and claimed.
In the accompanying' drawings, forming a part of this s ecification, Figure 1 is a sectional view o the valveV embodying my imrovement, and Fi 2 is a similar view show- 1n in addition to t 1e construction illustreted seat 1n case of its becoming stuck thereto.
In the ractice of my invention the stem 1 of the vs ve 2, whichcontrols the low of fluid in the direction ofthe srrow b extends up through a sleeve 3, preferably 'orrned inteal with a cup-like piston 4, arranged in a chamber at one side of the main passa e of the valve. This piston is prevented om psssin down into the passage through the 4o valve y a shoulder 6. A cup-like piston 7 is arranged within the iston 4 and is connected by a sleeve 8 to t 1e stem 1 of the valve, so as to move up and down within the piston 4 with'tho stem 1. When liquid flows in the direction ofthe arrow t, the valve will be raised from itsseat until cheeked by means of an adjustable rod 9, having a threaded portion screwing through o threaded sleeve 11 in the top of. the valve. The pressure of the pullin fluid in the main passage of the valve will et first force upthe piston 4, if it has not been carried up byfriction with stem I of the valve, endas such pressure is reduced the piston 4 will gradually drop until it rests on theshoulder 6. This movement of the piston 4 is independent of the valve, its stem, or the piston 7.u As the valve returnsto its seat a fluid cushion will be formed between theV pistons 4 and 7,"and by thegradual esca. e of this Huid the valve will be allowed to ta e `its seat Without shock or lar.
It sometimes hap ens that the valve will sticky to its seat and, in order to release the vave and read'just the stop, which determines the automatic opening of the valve without emplofing an outside indicator, prevision is mede r connecting the valve-stem, esby a. couplin 10, to the stop-rodi), said coup-l ling being nin e sufiiciently long to permit e, movement of the valve and its stern independent of the stop-rod. The threaded portion of the sto -rod passes through en internally-threads sleeve 12, which is also externelly threaded, so as to screw through a threaded o enin in 'the valve. B screwing the rod t ong the sleeve the va ve can be held to its seat or its opening movement regulated.
'In` oesethe valve sticks the sleeve. is rotated thereh exerting s. pull on the sto `rod en throng the coupling to the stern o the valve the latter from its seat. After, the valve as beenreleased the sleeve is screwed into the casing unti a stop, ras the hand- Wheel 13 shuts against the valvefcssing When the sleeve has reached this position, the stop-rod will be so adjusted that the valve can be seated. When the sto -rod is connected bythe coupling to, the va ive-stem, provision is made as against raising the stoprod sorhigh as to lift the valve from its seat. To this end the sleeve is made of such. a. length that when screwed fully into the casing a shoulder 14 on the sto -rod will hear against the end of the sleeve efore the sto -rod is moved out far enough to shift the va ve.
