Description

l5 20 25 30 35 8306051-7 2 lucka är infäst i tvà eller flera punkter med tillhörande armar fästa på aklarna l, fig. 2. l5 20 25 30 35 8306051-7 2 door is attached to two or more points with associated arms attached to the shafts 1, fig. 2.

Fig. 2 visar i ändvy utseendet på en andra, jalusi- liknande utföringsform av spjället. Det framgår att man erhåller en viss förminskning av den totala genomström- ningsarean på grund av de med tätningar försedda tvär- balkarna 14, men detta är det pris man måste betala för uppnàende av den bättre tätningen. Axlarna 1 i fig. 2 är lagrade i lager 16 och manövreras med armar och.länkar på det sätt, som är brukligt vid jalusispjäll.Fig. 2 shows in end view the appearance of a second, shutter-like embodiment of the damper. It appears that a certain reduction in the total flow area is obtained due to the cross-beams 14 provided with seals, but this is the price one has to pay to achieve the better seal. The shafts 1 in Fig. 2 are mounted in bearing 16 and are operated with arms and links in the manner customary for shutters.

Den fjädrande infästningen ll och 12 av luckorna på armarna, fig. l, kan åstadkommas medelst spiralfjädrar eller andra slag av fjädrande komponenter, såsom gummi- kuddar m.m. I Om avståndet 3 i fig. 3 är tämligen stort i förhål- lande till avståndet Q mellan luftpassagerna kommer varje luckas anslag mot sin tätning 9 att ske under tämligen stor vinkel vl, vilket kan förorsaka mindre god tätning och stort slitage på tätningen. Genom att man utformar armen 4 så, att luckan 5 i obelastat tillstànd ej träffar tätningens 9 överkant och underkant samtidigt utan med en viss snedställning V3 kommer, när luckan sedan dras mot tätningarna via den ledande och fjädrande infästningen, nämnda lucka att träffa tätningen under vinkeln v2 från normalen till tätningen, d.v.s. nästan vinkelrätt mot densamma och därmed är problemet med det alltför sneda anslaget eliminerat. Axelns avstånd 3 från spjällväggen i fig. 3 kan varieras ända ned till 0 om spjällväggen ges viss utbuktning, vilket även eliminerar problemet med det alltför sneda anslaget mot tätningen men givetvis sam- tidigt komplicerar tillverkningen.The resilient attachment 11 and 12 of the doors to the arms, Fig. 1, can be provided by means of coil springs or other types of resilient components, such as rubber cushions etc. If the distance 3 in Fig. 3 is rather large in relation to the distance Q between the air passages, the impact of each hatch against its seal 9 will take place at a fairly large angle vl, which can cause less good sealing and large wear on the seal. By designing the arm 4 so that the door 5 in the unloaded condition does not hit the upper edge and lower edge of the seal 9 at the same time but with a certain inclination V3, when the door is then pulled towards the seals via the leading and resilient attachment, said door hits the seal at an angle v2 from normal to seal, ie almost perpendicular to it and thus the problem of the excessively oblique stop is eliminated. The distance 3 of the shaft from the damper wall in Fig. 3 can be varied all the way down to 0 if the damper wall is given a certain bulge, which also eliminates the problem of the too oblique abutment against the seal but of course at the same time complicates the manufacture.

Konstruktionen är ej bunden till att luckorna skall vara kopplade parvis utan kan där så är lämpligt fungera med endast en lucka på varje axel.The construction is not bound to the doors being connected in pairs, but can, where appropriate, function with only one door on each shaft.

Om det är fråga om varma gaser, t.ex. rökgaser, kan tätningen utföras t.ex. så som antyds i fig. 4, d v s som en typ av sandlás eller med en packning av fläta eller band av keramisk fiber, som finns att tillgå för tempera- turer ända upp till 10000 C. Genom den ledande infäst- 10 15 20 25 30 35 8506051-7 3 ningen erhåller man ett jämnt tryck runt hela luckans kant även vid dessa höga temperaturer. Den fjädrande komponenten bör vid högre temperaturer förläggas utanför det varma utrymmet om temperaturen är så hög, att metal- liska fjädrar ej behåller sin elasticitet. Om så sker måste man givetvis arbeta med endast en ledande infäst- ning av spjälluckan eller -luckorna.In the case of hot gases, e.g. flue gases, the sealing can be performed e.g. as indicated in Fig. 4, i.e. as a type of sand lock or with a gasket braid or strip of ceramic fiber, which is available for temperatures up to 10000 C. Through the conductive attachment 10 15 20 25 30 35 8506051-7 3, an even pressure is obtained around the entire edge of the door even at these high temperatures. The resilient component should be placed outside the hot room at higher temperatures if the temperature is so high that metallic springs do not retain their elasticity. If this happens, you must of course work with only a conductive attachment of the damper door or doors.
