Definitions

  • zeolites for instance apparatus for the continuous softening of water by the use of hydrated alumina silicates, generally popularly known as zeolites.
  • the purpose of the invention is to intermittently, but at ysubstantially equally spaced intervals, withdraw liquid in suhstantially equal charges from a receptacle in which the liquid is under pressure.
  • the receptacle from which the liquid is withdrawn is the zeolite washing chamber.
  • This control valve can always be used to withdraw liquid from a receptacle under higher pressure than that into which the outlet discharges; even if thepressure. in ⁇ the ⁇ first ⁇ receptacle is merely atmospheric providing that of the second is then vbelow 'atmospheric pressure.
  • Fig. 1 is a vertical aXial section of the' control va'lve of a zeolite water softening apparatus and attendant parts with lthe valve open, y
  • Fig. 2 a detail is a perspective view. ⁇ of the poppet slug
  • Fig. 3 a detail, is a perspective View of the ring sluv.
  • Fig. 4 isnhe same as Fig. 1, but with the valve closed, the ring slug being in mid position, as '1t is falling.
  • 1 represents the valve housing, 2, a sediment chamber into which the liquid (spent brine from the zeolite washing chamber not shown), flows through the pipe 3 and 'thence upwardly through theV opening 4 forcing the Such apparatuses for thecontmuous sof-tpoppet slug 5 and the ring slug 6 (which' two in combination form a rather loose fitting piston in the tube 7 until the apex 8 of the slug strikes the pusher pin 9, seated axially so as to afford limited vertical movement of the pusher pin inthe hole 10 bored to receive it in the valve housingl.
  • the rising piston 5-6 forces the water above it in the chamber 11 through ⁇ the opening 12 in-the pusher pin into the cham'- ber 13 forcing upwardly the fiexible diaphragm 14 and the weight 15 seated thereon.
  • the outlet 16, which is always open, is arranged to require a predetermined longer time tolet out the water inthe chamber '13 than is required to let it in through the opening 12 in the pusher pin 9. This differential allows the seated piston to be raised by the force of the water until the slug 5 pushes up the pusher pin 9 and' seats itself against the seat 17, preferably resilient, on the under side ofthe'housing v1.
  • the poppet slug closes the opening 10 between the chambers 11 and 13 and stops the upward flow of liquid; whereupon the ring slug 6 immediately falls to the posi-fl tion shown in Figure 1 by gravity.
  • a stud, 18, passes through the diaphragm 14 and yis secured to the Weight 15' above, while below it has a shoulder 19 against whicha spring 20 rests and to which said spring is secured.
  • the lower end of this spring seats upon the top of the pusherpin 9 toinsure that the poppet slug will 'be thrown clear of its seat when unseated by the descending weight 15.
  • valvehousing 1 and its cap 21 have lateral circumferential flanges 22 and 23 respectively, between which rests the diaphragm 14 which is held securely in position by the stud bolts 24 and lock nuts 25. These bolts are produce'dupwardly forming guides for the weight 15.
  • a slug receptacle 2611- acts as apartial closure for the top of the sediment chamber 2 and as a seat for the botcentric with the axial opening 29.
  • the valve 5 6 has seated, the diaphragm stops rising and as the water discharged through the outlet 16 and the weighted diaphragm gradually descends, the spring 20, fixed to the shoulder 19, presses on the pusher pin 9 with sufficient forceto dislodge. the slug 5 from its seat, allowing water to flow around the slug 5, whereupon it Jfalls into contact with the ring slug 6., sealing ott the opening 29 in the ring slug so that elements 5 and 6 in combination ⁇ form a piston and will rise together as hereinbetore described.. l/Vhile the slug 5 is falling, the liquid below it flows past it into the chamber ll.
  • the cock 3l. is provided to draw oli' sediment from the apparatus.
  • the effective size oi' the. opening l5 may be regulated by a manually operated cock 32 or by a mechanically operated valve.
  • a control valve having a piston 'formed of a plurality of parts which automatically engage to co-act and constitute an edective piston and then automatically disengage.
  • a piston consisting oi? two elements, which automatically engage to coact and constitute an effective piston and then automatically disengage.
  • a control valve comprising a cylinder connected by a member having a passage to a chamber, a plurality of parts within "said cylinder which when co-actii'ig form an ci tective piston adapted to deliver substantially accurately measured charges of liquid to said chamber and then close said passage between said cylinder and said chamber and means for automatically reopening' said pas sage to allow the cri-acting parts in the cylinder to deliver another charge to the chamben said cycle of events being continuously and automatically maintained.
  • said piston parts vadapted in extreme raised' position to close said connection whereupon the other piston part or parts fall by grav ity to the bottom of the cylinder9 means for allowing the liquid to escape from said. chamber more slowly than it enters thru said connection and means within said chamber for unseating said connection closing piston part upon the escape of a predetermined quantity ot liquid from said chamber, whereupon said connection closing piston part falls by gravity into cri-acting Contact with the other piston part or parts.
  • a control valve for withdrawing liquid in substantially uniornrcharges having in combination a cylinder, a chamber and a liquid connection .from said cylinder to said chamber? a piston in said cylinder formed of a plurality of parts which under the pressure of ⁇ V inilowing liquid co-act to form an effete piston adapted to deliver a substantially accurately measured charge of liquid from said cylinder to said chamber, one of said piston parts adapted in extreme raised position to close said connection whereupon the other part or parts fall by gravity to the bottom of the cylinder, means for allowing the liquid to escape said chamber more slow y than it enters thru said connection, a diaphragm within said chamber adapted to be liexed upwardly by the liquid forced thru said connection into said chamber; a plunger, with a longitudinal liquid passage reciprocable in said connection, means for depressing' said diaphragm and means for forcing said plunger downwardly to unseat said connection closing piston part when said diaphragm has been depressed whereupon said connection closing piston part falls by gravity into co
