Description

Heating oil door

Openings on boilers are sealed gas-tight with yours, flaps or lids, which are usually provided with thermal insulation. So that the door leaf lies close to the door frame or directly to the water-cooled boiler wall, a circumferential groove is usually provided on the outer edge ₉ into which a cord made of asbestos, aluminum or a similar hit-resistant and sealing material is inserted. This sealing cord becomes a corresponding sealing strip assigned to the door frame »Conversely, it is also possible to insert the sealing cord into a groove in the door frame and provide the sealing strip on the door leaf.

If a particularly good seal is to be achieved, it is appropriate to have several sealing cords, preferably parallel to one another to be provided, which then also face several sealing strips. It can also be used between the sealing strips a cord can be inserted. There is a multiple labyrinthine sealing.

The hit of the present! Fire is supposed to be the thermal insulation and the Sealing of boiler doors can be improved. The door leaf consists of the door leaf cover and the door leaf inner part arranged at a distance from the door cover.

The furnace is characterized by the fact that the door leaf hood. and the door leaf inner part firmly with each other without direct contact are connected, and that the circumferential gap between the Sürbla / bthaube and the door leaf inner part one or more adjacent Forms grooves for receiving sealing cords, then corresponding sealing strips on the door frame and on the heating

As already described, the seal can be laid side by side improved by several sealing cords and corresponding sealing strips on the door frame arranged on these diGlitscJinüren will. The present innovation now allows it in the simplest possible way ! ■ / iron to readjust the seals, moreover. To this end is placed in the gap between the door leaf hood and the door leaf— inside a circumferential, adjustable by spindles bar arranged 9 which engages with a collar behind the sealing cords and with which the sealing cords can be pressed against the sealing strips »This strip can be designed in such a way * that not just the sealing cords against the sealing strips on the door frame pressed on \ <\? erd @ n »but that there is a protruding bridge also press against a sealing cord inserted between two sealing strips on the door frame. "- v

Thermal insulation and sealing thus throw through the connection a door leaf hood and a door leaf inner part improved to form a unit »with the simplest way to readjust the Seals is made possible. The thermal insulation is also improved by the fact that a few narrow ones on the inner part of the door leaf Bridges are attached »through which direct contact between the door leaf hood and the door leaf inner part is prevented. The accompanying drawings show exemplary embodiments of the control o Ss show;

The door leaf hood 1 , the door leaf inner part 2 and the insulation S lying between them are firmly connected to one another in the case of the door lock 4. Instead of the insulation 3, brackets can also be cast on one of the two parts, which guarantee the distance between parts 1 and 2, but keep the metallic contact surface very small. In this case there is an air gap between the outer and inner part of the door leaf, so the circumferential gap between the door leaf hood

iiuo. the Türblattinnentsil 2 is as a groove for receiving elaer or more. Sealing cords 5 formed, which on the water-bearing boiler wall 6 corresponding sealing strips 7 opposite. A direct contact is established by a few spacer cams 14 on the edge of the inner leaf part 2 Avoid swiping both parts as much as possible. Between two Sealing strips 7 another sealing cord 8 is inserted, on which the circumferential, between the two sealing cords 5 ' lying web 9 is applied.

This circumferential web can be designed as a separate strip 10 which engages with a collar 11 behind one or more parallel sealing cords 5 and the screws 12 distributed on the edge of the door leaf can be adjusted via corresponding spindles i3. If the strip 10 is pushed further out of the door by turning the screws 12, it presses the web 9 and the sealing cords 5 more firmly against the sealing strips 7 and on the sealing cord, S. In this way, the boiler door is sealed on the door frame much improved »

The adjustment of the seal with a built-in bar is also possible with a seal with only a single sealing cord after 2? 1 possible because the collar of the inner part of the door leaf, shown there, is the foremost one, reaching behind the sealing cord ]? surface of the contact strip is formed »
