Abstract

The invention relates to a vacuum valve (1) for closing a flow path (F) in an airtight manner by linear movement, the vacuum valve comprising: a closing member (5), which is linearly displaceable; a second part of the valve housing (2) A sealing surface (10), the first sealing surface closing the opening (3); and, a second sealing surface (11) of the closing member (5), the second sealing surface corresponding to the first sealing surface (10). In the closed position (C), the second sealing surface (11) is in sealing contact with the first sealing surface (10), said contact being pressed against the first sealing surface (10) in the closing direction (8), and the closing member ( 5) Close the opening (3) in an airtight manner. In the area between the opening (3) and the first sealing surface (10), the valve housing (2) comprises a first inclined surface (22) closing the opening (3), and the closing member (5) comprises a first inclined surface parallel to the first inclined surface (22) extends and corresponds to the second inclined surface (23) of the first inclined surface (22). The inclined surfaces ( 22 , 23 ) having an inclination angle ( 24 ) between 3 and 15 degrees relative to the geometrical adjustment axis ( 6 ) are positioned relative to each other such that in the closed position (C) of the closing member ( 5 ), p. The two inclined surfaces ( 23 ) are arranged in parallel positions opposite to the first inclined surface ( 22 ), and have a distance (v) of 0 to 0.6 mm between them.

Description

technical field [0001] The invention relates to a vacuum valve and a corresponding closing member which closes a flow path in an airtight manner by linear movement. Background technique [0002] Said vacuum valve and said closing member are known in particular in the form of delivery valves developed by the company VATVakuumventile AG of Haag, Switzerland under the product designation "MONOVAT series 02 and 03" rectangular plug-in valves. The design and method of operation of such valves are described schematically in eg US 4,809,950 (Geiser) and US 4,881,717 (Geiser). [0003] In general, vacuum valves are known from various embodiments from the prior art, which close a flow path leading through an opening realized in a valve housing in a substantially gas-tight manner. Vacuum gate valves are used in particular in the field of integrated circuit and semiconductor production, which must be carried out in a protected atmosphere, where possible free from contaminating particl...
