Description

462 178 för högtryck, vilket skulle medföra en ökad komplexitet med avseende på konstruktion, material och utrymesbehov. Dessutom undviks glidande rörelser av tätningsytorna, såsom vid en slidventil. 462 178 for high pressure, which would lead to an increased complexity with respect to construction, materials and space requirements. In addition, sliding movements of the sealing surfaces are avoided, such as with a slide valve.

Eftersom ventilen är anordnad för användning vid värmebehandlingsugnar är den utsatt för höga temperaturer. Därför föreslås som vidareutveckling av upp- finningen en vattenkylning vid ventilskivan och/eller vid ventilsätet- För att skydda ventilskivan och ventilsätet från värmestrålning, vilken kan komma från högtrycksbehållarens inre, är vidare ett strålningsskyddsbleck anordnat på hög- trycksbehållarens insida.Because the valve is designed for use in heat treatment furnaces, it is exposed to high temperatures. Therefore, as a further development of the invention, a water cooling is proposed at the valve disc and / or at the valve seat. To protect the valve disc and the valve seat from heat radiation, which may come from the interior of the high-pressure container, a radiation shield is further provided on the inside of the high-pressure container.

Uppfinningen skall nu beskrivas närmare med hänvisning till figuren.The invention will now be described in more detail with reference to the figure.

Med 1 betecknas en ventilskiva, vilken från högtryckssidan pressas mot tätningsytan 2. Tätningen sker med tätningsringen 3. ventilskivan förflyttas med hjälp av ett handhjul 5 via en gängspindel 4 vinkelrätt mot tätningsytan 2.Denoted by 1 is a valve disc, which from the high-pressure side is pressed against the sealing surface 2. The sealing takes place with the sealing ring 3. the valve disc is moved by means of a handwheel 5 via a threaded spindle 4 perpendicular to the sealing surface 2.

Med hjälp av en fjäderbälg 6 tätas ventilen vakuumtätt utåt.Med 7 beteck- nas högtrycksbehållarens vägg, i vilken befinner sig en kylkammare 8 för kylning av ventilsätet. För ventilskivan är Vattenkylning anordnad vid 9. Ventilhuset 10 är över en vakuumanslutning ll förbundet med en evakueringsanordning. Ett strål- skyddsbleck 12 skyddar ventilsäte och ventilskiva mot värmestrålning. 'xBy means of a spring bellows 6, the valve is sealed vacuum-tight to the outside. 7 denotes the wall of the high-pressure container, in which a cooling chamber 8 for cooling the valve seat is located. For the valve disc, water cooling is arranged at 9. The valve housing 10 is connected via a vacuum connection 11 to an evacuation device. A radiation protection plate 12 protects the valve seat and valve disc from heat radiation. 'x
