Embodiment Construction

[0028] The disc assembly of the instant disclosure is typically part of a valve. The valve provides a housing with at least one inlet and with at least one outlet. The valve according to the instant disclosure also provides a valve element.

[0029] figure 1 The valve element of the valve is shown. For this purpose, the housing of the valve is provided with a flange 1 . The fixed disk 2 is arranged adjacent to the flange 1 . The fixed plate 2 is made of ceramics, preferably engineering ceramics, still more preferably aluminum oxide (Al 2 o 3 ) and / or silicon carbide (SiC) and / or zirconium dioxide (ZrO 2 ) and / or magnesium oxide (MgO). The skilled person selects a ceramic material such as alumina with a suitable level of purity such as 92%, 96% or 99%. Higher levels of purity confer advantages in terms of mechanical sealing, mechanical fragility and dielectric strength.

[0030] In alternative embodiments, the fixed disk 2 is made of a metallic material such as (stainl...

Abstract

The invention discloses a valve with a ceramic disc. A valve assembly for modulating flow of a fluid through a valve, the valve assembly comprising a plunger (9), a flange (1) with an orifice (4), a first disc (2) with an orifice (6) and a second disc (7), a gasket (5, 5a, 5b) in contact with the flange (1) and in contact with the first disc (2), three bearing members (3a, 3b, 3c) disposed between the first disc (2) and the flange (1), the three bearing members (3a, 3b, 3c) define the position and the orientation of the first disc (2) with respect to the flange (1), the three bearing members (3a, 3b, 3c) separate the first disc (2) from the flange (1), thereby defining a gap between the flange (1) and said disc (2), the plunger (9) displaces the second disc (7) surfaces from a first position to a second position.

Description

technical field [0001] The present disclosure relates to valves having at least one ceramic disc. More particularly, the present disclosure is concerned with the arrangement of the ceramic disc inside the housing of the valve. The present disclosure also relates to circuits for heating, cooling, air conditioning and / or ventilation comprising valves with ceramic discs. Background technique [0002] The valves use ceramic discs as valve elements and / or as shut-off elements. Other uses of ceramic discs inside valves include, but are not limited to, throttling elements, elements for regulating or controlling gas flow or liquid flow, mixing or diverting elements, and the like. These valves typically include metal or polymer housings. [0003] German patent application DE102008017099A1 discloses a valve element with two valve plates 3a, 3b. The valve plates 3a, 3b are arranged perpendicular to the flow path through the valve. DE102008017099A1 figure 1 Shown are U-shaped valv...
