Description
448 770 ~ - 2 mellan trycken P1 och P2. Genom att använda ett bestämt för- hållande mellan kolvareorna kan man från ett givet tryck P2 i det första batteriet ernå ett önskat maximalt fyllníngstryck Pl i det andra batteriet. 448 770 ~ - 2 between pressures P1 and P2. By using a certain ratio between the carbon products, a desired maximum filling pressure P1 in the second battery can be obtained from a given pressure P2 in the first battery.
I det axiella hålet i kolven 9 är anordnad en strypnings- anordning l2. Denna är utformad som en hålförsedd vägg i kol- ven och anordnad att bestämma tryckökningen per tidsenhet, dvs gasflödet från det första batteriet med trycket P2 till det andra batteriet med trycket Pl. Genom att variera hålarean i strypningsanordningen kan önskat flöde genom överkopplingsven- tilen erhållas.A throttling device 12 is arranged in the axial hole in the piston 9. This is designed as a perforated wall in the piston and arranged to determine the pressure increase per unit time, ie the gas flow from the first battery with the pressure P2 to the second battery with the pressure P1. By varying the hole area in the throttling device, the desired flow through the transfer valve can be obtained.
I överkopplingsventilen är också arrangerad en backven- tilanordning, som tillåter gasflöde endast i riktning från det första batteriet med trycket P2 till det andra batteriet med trycket Pl. I hålrummet i mittpartiets l del mot gavelstycket 3, som är anslutet till batteriet med trycket P2, är anordnad en tvärställd plattal5, som är försedd med hål 7 för gaspas- sage. Plattan]5,är i sin centrumdel försedd med ett tappformat organ 6, som är anordnat att samverka med innerväggen i kolven 9. Vid ett visst läge på kolven kommer den att täta mot det tappformade organet medelst ett i tapporganet 6 anordnat pack- ningsorgan 8. Tapporganet 6 och en del av kolven utgör back- ventilanordningen. Överkopplingsventilen fungerar enligt följande. Om det antas att det andra batteriet som skall ha det normerade fyll- ningstrycket Pl har tömts på gas helt eller delvis och det första batteriet med det normerade trycket P2 är fyllt, träder ventilen i funktion. Kolven 9 kommer därvid att förskjutas mot gavelstycket 2, som visas på den övre halvan i figuren, på grund av den axialkraft, som uppstår då gastrycket P2 från det första batteriet påverkar kolvens 9 ändyta A2. Under kolvens rörelse kommer kolvväggen att lämna det tappformade organet 6 och gas kommer därigenom att passera genom strypningen 12 till det andra batteriet.A non-return valve device is also arranged in the transfer valve, which allows gas flow only in the direction from the first battery with the pressure P2 to the second battery with the pressure P1. In the cavity in the part of the middle portion 1 against the end piece 3, which is connected to the battery with the pressure P2, a transverse plate 5 is arranged, which is provided with holes 7 for gas passage. The plate 5, in its central part is provided with a pin-shaped member 6, which is arranged to co-operate with the inner wall of the piston 9. At a certain position on the piston it will seal against the pin-shaped member by means of a packing member 8 arranged in the pin member 6. The drain member 6 and a part of the piston constitute the non-return valve device. The transfer valve works as follows. If it is assumed that the second battery which is to have the normalized filling pressure P1 has been completely or partially emptied of gas and the first battery with the normalized pressure P2 is filled, the valve comes into operation. The piston 9 will then be displaced towards the end piece 2, which is shown on the upper half of the figure, due to the axial force which arises when the gas pressure P2 from the first battery affects the end surface A2 of the piston 9. During the movement of the piston, the piston wall will leave the pin-shaped member 6 and gas will thereby pass through the choke 12 to the second battery.
Trycket i detta batteri kommer därvid att öka. En axial- kraft som verkar på kolven i motsatt rikning kommer att byggas upp genom att gastrycket Pl påverkar kolvens ändyta Al. När denna axialkraft Pl x Al är lika stor som axialkraften P2 x A2 1:? kommer kraften mot gaveln 2 att upphöra. Då trycket Pl i det andra batteriet sedan ytterligare ökar, kommer axialkraften i riktning mot gaveln 3 att överväga, vilket innebär att kolven 9 rör sig mot gaveln 3. Kolven 9 kommer då så småningom att inta det läge som visas på den nedre halvan av figuren. Back- ventilanordningen blir på detta sätt stängd, så att gas för- hindras att passera från det första batteriet till det andra.The pressure in this battery will then increase. An axial force acting on the piston in the opposite direction will be built up by the gas pressure P1 affecting the end surface A1 of the piston. When this axial force P1 x A1 is equal to the axial force P2 x A2 1:? the force against gable 2 will cease. As the pressure P1 in the second battery then further increases, the axial force in the direction of the end wall 3 will consider, which means that the piston 9 moves towards the end wall 3. The piston 9 will then eventually assume the position shown in the lower half of the figure. . The non-return valve device is closed in this way, so that gas is prevented from passing from the first battery to the second.
Det andra batteriet är därmed fyllt med gas av ett tryck lika med Pl.The second battery is thus filled with gas of a pressure equal to P1.
Ett exempel på lämpligt användningsområde för den uppfin- ning som beskrivits i det föregående är som överkopplingsan~ ordning i en gascentral för en gasdistributionsanläggning, varvid det första batteriet motsvaras av gascengralens drift- batteri och det andra batteriet motsvaras av reservbatteriet i gascentralen. Genom att utgå från ett bestämt maxtryck i drif- tbatteriet, t ex 200 bar och genom att utforma förhållandet mellan kolvens ändytor på ett bestämt sätt, kan man sålunda uppnå ett önskat fyllningstryck, t ex 150 bar i reservbatteri- et. Genom att dessutom ge arean i strypningshålet en lämplig dimension, kan ett önskat fyllningsförlopp (fyllningshastig- het) för fyllning av reservbatteriet erhållas.An example of a suitable field of application for the invention described above is as a switching device in a gas exchange for a gas distribution plant, the first battery corresponding to the operating battery of the gas central and the second battery corresponding to the spare battery in the gas exchange. By starting from a certain maximum pressure in the operating battery, for example 200 bar and by designing the ratio between the end surfaces of the piston in a certain way, a desired filling pressure can thus be achieved, for example 150 bar in the spare battery. By also giving the area in the choke hole a suitable dimension, a desired filling process (filling speed) for filling the spare battery can be obtained.
