Abstract

The regulating and measurement unit (2,3,4) is for the input air flow (8) to a room and comprises a perforated tube cover coupled to an input air tube (1). An axially movable regulating damper provided with nozzles is located inside the tube cover.

Description

25 30 525 716 2 luftströmmaina i hela byggnaden för att få slut på klagomålen. Detta åter leder till en situation där energiförbrukningen i byggnaden ökar utan någon “rimlig” förklaring. 25 30 525 716 2 airflow mains throughout the building to put an end to the complaints. This in turn leads to a situation where the energy consumption in the building increases without any "reasonable" explanation.

I och för sig kända inluftsanordningar och apparater för att mäta och reglera inluft har beskrivits i FI-patenten 71614 och 81666 samt i patentansökningarna 20000681, 2001767 och 20020173.Known air devices and apparatus for measuring and regulating air air per se have been described in FI patents 71614 and 81666 as well as in patent applications 20000681, 2001767 and 20020173.

Nackdelen med exempelvis den enhet för att mäta och reglera luftströmmar som beskrivs i FI-patentansökan 20020173 har varit den, att man svårligen fått till stånd en tillräckligt tät spalt mellan rönnanteln och reglerspjället. Det är ytterst svårt att åstadkomma en fullt cirkulär rörmantel, då dess fogpunkt ofta blir plan till följd av rörvalsningsteknik. Ifall man eftersträvar små spalttoleranser, leder detta till svårigheter och motstånd då reglerspjället skall flyttas i rörmanteln.The disadvantage of, for example, the unit for measuring and regulating air flows described in FI patent application 20020173 has been that it is difficult to create a sufficiently tight gap between the rowan jacket and the control damper. It is extremely difficult to achieve a fully circular pipe jacket, as its joint point often becomes flat as a result of pipe rolling technology. If small gap tolerances are sought, this leads to difficulties and resistance as the control damper must be fl surface in the pipe jacket.

Avsikten med denna uppfinning år att åstadkomma en enhet för att mäta och har relativt enkel konstruktion, är funktionssåker, är lätt att reglera och dessutom är relativt ljudlös. Enheten enligt reglera luftströmmar av ny typ, uppfinningen kännetecknas av att en flexibel tätning inspänts vid reglerspjällets kant och vikts parallellt med rörmanteln från och med kanten av reglerspjället.The object of this invention is to provide a unit for measuring and has a relatively simple construction, is functional, is easy to control and is also relatively quiet. The unit according to regulating air flows of a new type, the invention is characterized in that a flexible seal is clamped at the edge of the control damper and folded parallel to the pipe jacket from the edge of the control damper.

Olika utföringsformer av uppfinningen beskrivs i de osjälvständiga patentkraven i patentkravsuppställningen.Various embodiments of the invention are described in the dependent claims in the statement of claims.

Uppfinningen förklaras nedan med hjälp av ett exempel och med hänvisning till bifogade ritning, där Figur l illustrerar en enhet för att mäta och reglera luftströmmar i genomskårning och Figur 2 är en förstoring av punkt Il i figur l. 10 525 716 3 Enheten för att reglera och mäta luftströmmar består av en perforerad rönnantel 2 kopplad till ett inluftsrör l, varvid rörrnanteln irmesluter ett axialt rörligt regler- spjäll 4 försett med dysor 3.The invention is explained below by means of an example and with reference to the accompanying drawing, in which Figure 1 illustrates a unit for measuring and regulating air flows in section and Figure 2 is an enlargement of point II in Figure 1. The unit for regulating and measuring air currents consists of a perforated casing jacket 2 connected to an inlet air pipe 1, the pipe casing enclosing an axially movable control damper 4 provided with nozzles 3.

Vid reglerspjällets 4 kant finns fastspänt en elastisk tätning 5, som vikts utgående från reglerspjållets 4 kant parallellt med rörmanteln 2. Tätnirigen 5 är tillverkad av ñlttyg, och glider sålunda lätt och tätt slutande mot rörmantelns 2 inre yta vid reglering. Tätningen 5 är fastspänd vid reglerspjâllet 4 med en fâstring 6 och nitar 7. Tåtningen 5 år vikt i samma riktning som luftströmmen 8, så att längden av dess vikta kant inte påverkar den reglering regler- och mätenheten utför.At the edge of the control damper 4 an elastic seal 5 is clamped, which is folded starting from the edge of the control damper 4 parallel to the pipe jacket 2. The sealing ring 5 is made of fabric, and thus slides easily and tightly closing against the inner surface of the pipe jacket 2 when adjusting. The seal 5 is clamped to the control damper 4 with a fastening ring 6 and rivets 7. The seal 5 is folded in the same direction as the air flow 8, so that the length of its folded edge does not affect the control performed by the control and measuring unit.
