Description
Drivanordning for ventiler. Drive device for valves.
Foreliggende oppfinnelse angår en drivanordning for ventiler, særlig klaffventiler og seteventiler som er trykkmediumdrevet ved hjelp av en sylinder med et drivstempel og stempelstang der stempelstangen er forlenget på den side som vender fra ventilen, hvilken forlengelse er beregnet på å samvirke med et låsestempel som med trykkluft kan pådras for frigjøring av stempelstangens bevegelse og dermed for åpning av ventilen, idet låsestemplets bevegelsesretning går på tvers av bevegelsesretningen for stemplet som påvirker ventilen og at låsesylinderens stempel har en tversgående boring som ved påvirkning av trykkluft på stemplet kan bringes i flukt med den nevnte forlengelse. The present invention relates to a drive device for valves, in particular flap valves and poppet valves which are driven by pressure medium by means of a cylinder with a drive piston and piston rod where the piston rod is extended on the side facing away from the valve, which extension is intended to cooperate with a locking piston as with compressed air can be incurred for releasing the movement of the piston rod and thus for opening the valve, as the direction of movement of the locking piston goes across the direction of movement of the piston that affects the valve and that the piston of the locking cylinder has a transverse bore which can be brought into alignment with the aforementioned extension by the action of compressed air on the piston .
Por spesielle typer ventiler av den art det her er Por special types of valves of the kind here
tale om krever sjøfartsmyndighetene at de skal kunne stenges og åpnes ved pneumatisk påvirkning og dessuten skal det tydelig angis om ventilen er åpen eller lukket. in question, the maritime authorities require that they must be able to be closed and opened by pneumatic action and, moreover, it must be clearly indicated whether the valve is open or closed.
De løsninger man kjenner til fra før er imidlertid The solutions known from before are, however
meget kompliserte og så kostbare at de. på tross av ventiltypenes fordeler har fått liten utbredelse.. very complicated and so expensive that they. despite the advantages of the valve type, has gained little spread..
Formålet med oppfinnelsen er derfor å komme frem til The purpose of the invention is therefore to arrive at
en drivanordning som på en enkel måte tilfredsstiller myndighetenes krav, og drivanordningen i henhold til oppfinnelsen kan lukke og låse en ventil og frigjøre ventilen for åpning med bare to tilførselsled-ninger for trykkluft. Dette forenkler videre ledningsopplegget, a drive device which in a simple way satisfies the authorities' requirements, and the drive device according to the invention can close and lock a valve and release the valve for opening with only two supply lines for compressed air. This further simplifies the wiring arrangement,
og de pneumatiske sylindre som er nødvendige er rimelige' i fremstil-ling og meget driftssikre. I henhold til oppfinnelsen er dette opp-nådd ved at den pneumatiske låsesylinder er utstyrt med en returfjær som på i og- for seg kjent måte pådrar låsestemplet mens drivsylinderen er forsynt med en i og for seg kjent returfjær, hvilken fjær samvirker i stengt eller låst stilling for ventilkammeret. and the pneumatic cylinders that are necessary are inexpensive to manufacture and very reliable. According to the invention, this is achieved by the pneumatic locking cylinder being equipped with a return spring which engages the locking piston in a manner known per se, while the drive cylinder is provided with a return spring known per se, which spring cooperates in closed or locked position for the valve chamber.
Et- annet trekk ved oppfinnelsen består i at låsestemplet har en forlengelse som stikker ut av låsesylinderen og er forsynt med innretninger for manuell betjening. En hensiktsmessig utførelses-form er kjennetegnet ved at stemplet i låsesylinderen på i og for seg kjent måte har en skråflate som er innrettet til ved forskyvning av stemplet ved hjelp av fjæren, å drive forlengelsen på stemplet i betjeningssylinderen i en slik retning at ventilen stenger. Another feature of the invention is that the locking piston has an extension that protrudes from the locking cylinder and is equipped with devices for manual operation. An appropriate embodiment is characterized by the fact that the piston in the locking cylinder has, in a known manner, an inclined surface which is designed to, by displacement of the piston with the help of the spring, drive the extension of the piston in the operating cylinder in such a direction that the valve closes.
For at oppfinnelsen lettere skal kunne forstås vil den In order for the invention to be easier to understand, it will
i det følgende bli beskrevet nærmere under henvisning til tegningen, som viser et snitt gjennom en klaffventil som her er valgt som eksempel. Ventilklaffen 1 er vist anbrakt i et rørstykke 2 og den er hengslet svingbart ved 3. På rørstykket 2 finnes en gjenget stuss H beregnet på anbringelse av en drivanordning. Drivanordningen har en driv-sylinder 5 med drivstempel 6 i den utførelsesform som er er valgt for å illustrere oppfinnelsen, og drivstemplet 6 har en stempelstang 7 in what follows will be described in more detail with reference to the drawing, which shows a section through a flap valve which has been chosen here as an example. The valve flap 1 is shown placed in a piece of pipe 2 and it is pivotably hinged at 3. On the piece of pipe 2 there is a threaded spigot H intended for fitting a drive device. The drive device has a drive cylinder 5 with a drive piston 6 in the embodiment chosen to illustrate the invention, and the drive piston 6 has a piston rod 7
som virker på en knast 8 på ventilklaffen 1. På den side som vender fra stempelstangen 7 har drivstemplet 6 en forlengelse 9 som er beregnet .på å virke sammen med en lås, som generelt er betegnet med 10.. Låsen omfatter en sylinder 11 med stempel 12 og dette stempel kan beveges frem og tilbake i sylinderen og har en boring 1J med så stor which acts on a cam 8 on the valve flap 1. On the side facing from the piston rod 7, the drive piston 6 has an extension 9 which is intended to work together with a lock, which is generally denoted by 10. The lock comprises a cylinder 11 with piston 12 and this piston can be moved back and forth in the cylinder and has a bore 1J with as large
diameter at forlengelsen 9 på drivstemplet 6 kan stikke gjennom boringen når denne og forlengelsen 9 er i flukt med hverandre. Stemplet 12 pådras av en fjær lH, som søker å forskyve stemplet slik at boringen 13 bringes til side-for forlengelsen 9- Man får da den situasjon som er vist på tegningen, der ventilklaffen 1 er låst i lukket stilling. diameter that the extension 9 of the drive piston 6 can stick through the bore when this and the extension 9 are flush with each other. The piston 12 is applied by a spring lH, which seeks to displace the piston so that the bore 13 is brought to the side - for the extension 9 - You then get the situation shown in the drawing, where the valve flap 1 is locked in the closed position.
Sylinderen 11 er ved en stuss 15 tilsluttet et pneumatisk fjernstyringssystem, og ved tilførsel av trykkluft drives stemplet 12 til høyre på tegningen, slik at boringen 13 bringes over forlengelsen 9- Hvis nu ventilklaffen 1 står under påvirkning av trykk fra det medium som skal strømme i ledningen 2, vil klaffen fritt kunne løfte seg, hvorved stempelstang 7, drivstempel 6 og forlengelse 9 løftes, og forlengelsen 9 glir inn i boringen 13. Stemplet 6 er ifølge oppfinnelsen forsynt med en returfjær 16. Når nu tilførselen av trykkluft opphører og stemplet 12 i låsesylinderen 11 ikke lenger drives mot høyre på tegningen, vil forlengelsen 9 hindre stemplet i å gå tilbake. The cylinder 11 is connected to a pneumatic remote control system by a nozzle 15, and when compressed air is supplied, the piston 12 is driven to the right in the drawing, so that the bore 13 is brought over the extension 9- If now the valve flap 1 is under the influence of pressure from the medium that is to flow in line 2, the flap will be able to lift freely, whereby the piston rod 7, drive piston 6 and extension 9 are lifted, and the extension 9 slides into the bore 13. According to the invention, the piston 6 is provided with a return spring 16. When the supply of compressed air ceases and the piston 12 in the locking cylinder 11 is no longer driven to the right in the drawing, the extension 9 will prevent the piston from going back.
Når klaffventilen skal lukkes, tilføres drivsylinderen When the butterfly valve is to be closed, the drive cylinder is supplied
5 trykkluft gjennom en stuss 17, og trykkluften driver stemplet 6 med stempelstangen 7 ned og tvinger klaffventilen 1 igjen mot trykk-virkningen fra det medium som strømmer i rørledningen 2. Straks driv-stemplets 6 forlengelse 9 kommer så langt ned at den går klar av boringen i låsestemplet 12, vil fjæren lh drive stemplet mot venstre på tegningen og hindre drivstemplet 6 med stempelstangen 7 og forlengelsen 9 i å bevege seg opp når tilførselen av trykkluft til drivsylinderen 5 opphører.'I en foretrukken utførelsesform har stemplet 12 en skråflate 18 som med en kilevirkning driver stempelstangen 7 mot ventilklaffen 1, slik at denne holdes i tett anlegg mot sitt sete. Por å kunne betjene ventilen også når trykklufttilførselen svikter, er stemplet 12 i låsesylinderen 11 forsynt med et organ 19 for manuell betjening idet man ved å trekke dette til høyre på tegningen, trekker stemplet 12 mot virkningen av fjæren l1) på samme måte som det beveges ved tilførsel av trykkluft. 5 compressed air through a nozzle 17, and the compressed air drives the piston 6 with the piston rod 7 down and forces the flap valve 1 again against the pressure effect of the medium flowing in the pipeline 2. Immediately the extension 9 of the drive piston 6 comes down so far that it clears the bore in the locking piston 12, the spring lh will drive the piston to the left in the drawing and prevent the drive piston 6 with the piston rod 7 and the extension 9 from moving up when the supply of compressed air to the drive cylinder 5 ceases. In a preferred embodiment, the piston 12 has an inclined surface 18 which with a wedge effect, the piston rod 7 drives against the valve flap 1, so that it is held in tight contact with its seat. In order to be able to operate the valve even when the compressed air supply fails, the piston 12 in the locking cylinder 11 is provided with a device 19 for manual operation, by pulling this to the right in the drawing, the piston 12 is pulled against the action of the spring l1) in the same way as it is moved by supplying compressed air.
