Description
Anordning for hurtig stengning av en ventil, særlig ved fjernnianøvrering. Device for quick closing of a valve, especially in case of remote actuation.
Foreliggende oppfinnelse angår en anordning for hurtig stengning av en ventil, The present invention relates to a device for quickly closing a valve,
særlig ved fjernmanøvrering, og som omfatter et mellom to endestillinger bevegelig especially in the case of remote manoeuvring, and which includes a moveable between two end positions
ventillegeme, som ved inngrep mellom et valve body, as in the case of engagement between a
manuelt påvirkbart sperreorgan og en med manually actuated locking device and a med
det forbundet ventilstamme er anordnet the connected valve stem is arranged
for normalt å fastholdes i åpen stilling under motvirkning av kraften fra en fjær e. 1. to normally be maintained in the open position under the counteraction of the force from a spring e. 1.
og når inngrepet oppheves ved fjernmanøv-rering av sperreorganet, av nevnte kraft and when the intervention is canceled by remote operation of the locking device, by said force
hurtig føres til stengt stilling. quickly moved to the closed position.
Ventiler av denne art forekommer i Valves of this kind occur in
mange forskjellige forbindelser, f. eks. ombord i fartøyer, i oljeraffinerier og i liknende anlegg innen den kjemiske industri. many different compounds, e.g. on board vessels, in oil refineries and in similar facilities within the chemical industry.
Muligheten for å frembringe den hurtige The ability to produce the fast
bevegelse, såvel som å kunne fjernutløse movement, as well as being able to trigger remotely
denne, er et krav som stilles av vedkommende tilsynsmyndigheter for at ventilene, this, is a requirement set by the relevant supervisory authorities for the valves,
som altså vanligvis inngår i rørledninger which are therefore usually included in pipelines
for ildsfarlige væsker eller gasser, i til-felle det inntreffer en ulykke eller tilløp til for flammable liquids or gases, in the event of an accident or access to it
en ulykke, skal kunne stenge meget raskt. an accident, must be able to close very quickly.
På tilvarende måte stilles også av og til On an ongoing basis is also asked from time to time
det krav at åpningen skal kunne skje meget the requirement that the opening should be able to take place a lot
raskt, nemlig f. eks. ved ventiler av denne quickly, namely e.g. at valves of this
art som inngår i rørsystemet for distribu-sjon av ett eller annet ildslukningsprepa-rat. Utover dette kreves i de fleste tilfeller type that is part of the pipe system for the distribution of one or another fire-extinguishing preparation. Beyond this is required in most cases
at et større eller mindre antall ventiler skal that a greater or lesser number of valves should
kunne fj ernmanøvreres samtidig. Manøv-rerimpulsen kan i anlegg av denne at ut-løses enten manuelt, eller også automatisk could be remotely operated at the same time. In connection with this, the maneuvering impulse can be triggered either manually or automatically
i avhengighet av et signal som angis fra depending on a signal indicated from
ett eller annet alarmapparat. some alarm device.
Ved de hittil kjente anlegg av den ovenfor beskrevne art oppheves inngrepet mellom sperreorganet og ventilkj eglen på rent mekanisk vei, nemlig ved hjelp av liner eller stenger, som er koplet til sperreorganet. Det har imidlertid vist seg at man med en slik konstruksjon ikke i alle stillin-ger oppnår en fullt sikker funksjon, og at funksjonen til og med iblant kan utebli helt. Som eksempel kan anføres ventiler ombord i fartøyer. Disse ventiler består normalt av et ventilhus som er koplet inn i vedkommende rørledning, og forsynt med et ventilsete og et ventillegeme, som er fast forbundet med en stang eller spindel, som passerer gjennom en pakningsboks, og en-den av stangen eller spindelen som ligger utenfor pakningsboksen, samvirker med sperreorganet. Som ovenfor nevnt, trer ventilene i funksjon bare under unormale forhold, spesielt i faresituasjoner, idet de prøves med regelmessige mellomrom. Inter-vallene mellom prøvene er dog forholdsvis lange. Nå forholder det seg jo slik at ombord i fartøyer forekommer det stadig ma-ling av alle utvendige gjenstander, her-under naturligvis også rørledninger og til-hørende ventiler. Videre forgår målearbei-det regelmessig oftere enn de nevnte prøver, hvorav følger at av og til kan to eller flere målearbeider finne sted mellom to etter hverandre følgende prøver. Følgen blir at ventilenes utvendige deler, dvs. spindelen og sperremekanismen, ikke sjelden blir overtrukket med tykke malingsskikt, slik at når det kommer en utløpningspuls, så blir denne hemmet slik at ventilene enten slett ikke kan stenges, resp. åpnes, eller også på-virkes de så langsomt at den tilsiktede be-skyttelsesvirkning går tapt. Liknende feil oppstår iblant ved korrosjon, nedising eller annen ytre innvirkning. In the hitherto known installations of the type described above, the engagement between the locking device and the valve cone is canceled in a purely mechanical way, namely by means of lines or rods, which are connected to the locking device. However, it has been shown that such a construction does not achieve a fully secure function in all positions, and that the function can sometimes even fail completely. Valves on board vessels can be cited as an example. These valves normally consist of a valve body which is connected to the pipeline in question, and provided with a valve seat and a valve body, which is firmly connected to a rod or spindle, which passes through a stuffing box, and the end of the rod or spindle which is outside the packing box, cooperates with the locking device. As mentioned above, the valves only operate under abnormal conditions, especially in dangerous situations, as they are tested at regular intervals. However, the intervals between the samples are relatively long. Now the situation is such that on board vessels there is constant painting of all external objects, naturally including pipelines and associated valves. Furthermore, the measuring work takes place regularly more often than the aforementioned tests, from which it follows that occasionally two or more measuring work can take place between two successive tests. The consequence is that the external parts of the valves, i.e. the spindle and the locking mechanism, are not infrequently coated with thick layers of paint, so that when a discharge pulse occurs, this is inhibited so that the valves either cannot be closed at all, resp. are opened, or they are affected so slowly that the intended protective effect is lost. Similar errors sometimes occur due to corrosion, icing or other external influences.
Formålet for oppfinnelsen er å eliminere samtlige ovenfor anførte ulemper og feil ved tidligere kjente anordnin<g>er, idet oppfinnelsen er nærmere bestemt av den art hvor det anvendes et fjernmanøvrert hydraulisk eller pnevmatisk servostempel, som er innrettet til ved angivelsen av en manøvreringsimpuls dels å oppheve inngrepet mellom ventilstammen og sperreorganet. samt dels tvangsmessig å føre ventillegemet til sin lukkede endestilling, idet sperreorganets låseinngep oppheves ved dreining av dette, og anordningen ifølge oppfinnelsen karakteriseres ved at sperreorganet er utført med en armliknende del om er dreibart festet til ventilhusgodset eller en holder på dette, hvilken del på sperreorganet har slik stilling at det dreies av stempelet slik at låseinngrepet til sperreorganet oppheves innen, men ikke før, den nevnte tvangsmessi<g>e stegning av ventilen ved hielp av ventillegemet innledes, og at ventillegemet kan heves til sin åpne endestilling ved hielp av en til stammen festet og manuelt manøvrerbar hevarm hvortil også er festet sperretappen bestemt for inngrep med sperreorganet. The purpose of the invention is to eliminate all of the above-mentioned disadvantages and errors of previously known devices, as the invention is more specifically of the kind where a remote-operated hydraulic or pneumatic servo piston is used, which is designed to, when a maneuvering impulse is indicated, partly to cancel the engagement between the valve stem and the locking member. as well as partly forcing the valve body to its closed end position, as the locking mechanism of the locking device is released by turning it, and the device according to the invention is characterized in that the locking device is made with an arm-like part that is rotatably attached to the valve body or a holder on it, which part of the locking device has such a position that it is turned by the piston so that the locking action of the locking device is canceled before, but not before, the aforementioned forced raising of the valve with the help of the valve body is initiated, and that the valve body can be raised to its open end position with the help of another the stem attached and manually maneuverable lever to which the locking pin intended for engagement with the locking device is also attached.
Ved en foretrukket utførelsesform for onDfinnelsen er servostempelet med sin ytre ende utført konisk eller med en skrå flate som er bestemt til ved kilevirkning å samvirke med sperreorganets armliknende del under den innledende delen av sperreorganets frigjøringsbevegelse. In a preferred embodiment of the invention, the servo piston with its outer end is made conical or with an inclined surface which is intended to cooperate with the locking member's arm-like part during the initial part of the locking member's release movement by means of a wedge action.
En utførelsesform for oppfinnelsen skal beskrives nærmere i det følgende under henvisning til den vedlagte tegning. Fig. 1 viser, delvis i snitt, et sideriss av en ifølge oppfinnelsen anordnet ventil. Fig. 2 viser, også delvis i snitt, et pers-pektivriss av en anordning for avgivning av manøvreringsimpulser til ventilen iføl-ge fig. 1. An embodiment of the invention shall be described in more detail below with reference to the attached drawing. Fig. 1 shows, partially in section, a side view of a valve arranged according to the invention. Fig. 2 shows, also partially in section, a perspective view of a device for issuing maneuvering impulses to the valve according to fig. 1.
På tegningen betegner 1 et ventilhus med et lokk 2, som bærer en pakningsboks 3, gjennom hvilken passerer en ventilstamme 4. Til den nedre ende av denne er festet et tallerkenliknende ventillegeme 5, som samvirker med et ventilsete 6. 7 og 8 betegner inn- og utstrømningskanaler for det medium, hvis strømning reguleres med ventilen. Strømningen foregår i retningen 7—8 og ventilen er innrettet for å kunne stenges hurtig. For at dette skal kunne oppnås, omfatter anordningen dels en kraftig trykkfjær 9, innspent mellom lokket 2 og ventilhodet 5, og dels en sperremekanisme. Den sistnevnte består av et sperreorgan 10, som i låsestillingen griper rundt en tapp 11 anbragt mellom benene på en gaffelformet hevarm 12. Denne har i hvert av benene et avlangt hull 13, hvori det raker inn en med spindelen 4 fast forbundet stift 14. Hevarmen 12 er ført omkring en aksel 15, og sperreorganets 10 dreietapp er betegnet med 16. 17 betegner et håndtak for manøv-rering av sperreorganet. In the drawing, 1 denotes a valve housing with a lid 2, which carries a stuffing box 3, through which a valve stem 4 passes. To the lower end of this is attached a plate-like valve body 5, which cooperates with a valve seat 6. 7 and 8 denote in- and outflow channels for the medium, the flow of which is regulated with the valve. The flow takes place in the direction 7-8 and the valve is designed to close quickly. In order for this to be achieved, the device partly comprises a powerful compression spring 9, clamped between the lid 2 and the valve head 5, and partly a locking mechanism. The latter consists of a locking device 10, which in the locked position grips around a pin 11 arranged between the legs of a fork-shaped lifting arm 12. This has in each of the legs an elongated hole 13, into which a pin 14 firmly connected to the spindle 4 protrudes. The lever arm 12 is guided around a shaft 15, and the locking member 10's pivot pin is denoted by 16. 17 denotes a handle for maneuvering the locking member.
Den ovenfor beskrevne anordning er tidligere kjent. Ifølge oppfinnelsen er imidlertid ovenfor ventilstammen 4 og koaksialt med denne anordnet en hydraulisk servo-motor 19, hvis stempel 20, som altså kan forskyves mot og fra den øvre ende av spindelen 4, er utformet som en armliknende del 18 som er dreibart festet til ventilhusgodset. Trykkolje til sylinderen 19 tilføres giennom en ledning 21, hvis motsatte ende er forbundet med en pulssender (fig. 2) som normalt befinner seg i betydelig av-stand fra ventilen, og hvis konstruksjon skal beskrives nærmere i det følgende. Med 18 betegnes et knastliknende eller armliknende utspring på organet 10. hvilket utspring skyter ut inntil den nedre ende av sylinderen 19. The device described above is previously known. According to the invention, however, a hydraulic servo motor 19 is arranged above the valve stem 4 and coaxially with this, whose piston 20, which can therefore be displaced towards and from the upper end of the spindle 4, is designed as an arm-like part 18 which is rotatably attached to the valve housing . Pressurized oil to the cylinder 19 is supplied through a line 21, the opposite end of which is connected to a pulse transmitter (fig. 2) which is normally located at a considerable distance from the valve, and whose construction will be described in more detail below. 18 designates a knob-like or arm-like projection on the organ 10. This projection projects to the lower end of the cylinder 19.
Anordningens funksjon er følgende. The function of the device is as follows.
Ved hielp av hevarmen 12 løftes ventillegemet 5 fra setet, og låses deretter i åpen stilling ved at organet 10 føres til inngrep med tappen 11. Når en trykkpuls ved hjelp av senderen overføres til servomotoren 19, vil stempelet 20, som omfatter et konisk avfaset parti, med dette trykke mot knas-ten 18, og herved tvinge organet 10 ut av inngrep med tappen 11. Ventilen stenges altså hurtig under innvirkning av fjæren 9. Skulle imidlertid virkningen av meka-nismen bli hemmet eller hindret f. eks. av noen av de ovenfor nevnte årsaker, eller om fjæren skulle briste, så kommer den del av stemplet som befinner seg under den konis-ke del under stempelets 20 fortsatte ned-overbevegelse til å trykke mot spindelen 4 og hermed besørge stegningen av ventilen. Til forskjell fra forholdene ved de tidligere kjente anlegg sikres altså at stengning av ventilen under alle omstendigheter finner sted. Praktiske prøver har vist at man tak-ket være oppfinnelsen oppnår en fullgod beskyttelse i disse henseender, særskilt for-di jo risikoen for en feil på en hydraulisk manøvreringsanordning er meget mindre enn ved en mekanisk manøvreringsanord-ning, som omfatter liner, stenger o. 1., som også kan bli hemmet eller hindret i sin funksjon av de ovenfor nevnte eller andre With the help of the lever arm 12, the valve body 5 is lifted from the seat, and is then locked in the open position by bringing the member 10 into engagement with the pin 11. When a pressure pulse is transmitted to the servo motor 19 by means of the transmitter, the piston 20, which comprises a conical chamfered part , thereby pressing against the cam 18, and thereby forcing the member 10 out of engagement with the pin 11. The valve is therefore quickly closed under the influence of the spring 9. However, should the effect of the mechanism be inhibited or prevented, e.g. for any of the reasons mentioned above, or if the spring were to break, then the part of the piston which is located under the conical part during the continued downward movement of the piston 20 will press against the spindle 4 and thereby ensure the rising of the valve. In contrast to the conditions in the previously known facilities, it is therefore ensured that the valve closes under all circumstances. Practical tests have shown that, thanks to the invention, you achieve adequate protection in these respects, especially because the risk of a fault with a hydraulic maneuvering device is much smaller than with a mechanical maneuvering device, which includes lines, rods etc. 1., which may also be inhibited or hindered in its function by those mentioned above or others
årsaker. causes.
