摘要:
The invention relates to a heat-resistant cable bushing for a gas meter enclosure. Provided in the cable bushing are sealing means (15), which comprise a first material which is sealing and stable in a temperature range below a first temperature. In addition, the cable bushing has limiting means (17, 18), which are formed from at least one second material, which is stable in a temperature range above the first temperature. The limiting means (17, 18) are designed such that a gas flow passing through the cable bushing can be limited to a predetermined volume per unit time. The limiting means ensure that, in the event of the development of heat, by means of which the sealing means (15) lose their sealing effect, the gas flow passing through the cable bushing does not exceed a maximum tolerable volume per unit time.

The industrial burner (10) comprises a mixing chamber (3), which is provided with at least one opening (2) into a furnace room (1), through which opening at least a partially-mixed fuel flow from the mixing chamber (3) dispenses into the furnace room during operation, a combustion air supplier (15), through which the mixing chamber (3) is supplied with combustion air during operation, and a fuel supplier (I1 8), with which fuel is introduced into the mixing chamber, are provided. The fuel supplier (7, 8) can switch between a first and a second operation state, wherein in the first operation state, fuel is introduced into the mixing chamber (3) at a first angle (5) with respect to the axial direction of the mixing chamber such that fuel and air are mixed in the mixing chamber and at least a partial reaction is carried out therein, and in the second operation state, fuel is introduced into the mixing chamber (3) at substantially the same axial position with respect to the opening (2) as in the first operation state and additionally at least at a second angle (6) with respect to the axial direction of the mixing chamber. The first angle (5) differs from the second angle (6).

Druckregelgerät für Gase, insbesondere für Erdgas mit einem Gehäuse (1), das einen Einlasskanal (2) und einen Auslasskanal (3) aufweist, mit einer zwischen dem Einlasskanal (2) und dem Auslasskanal (3) angeordneten Durchtrittsöffnung (4), mit einem Regelventil-Teller (8), der mit der Durchtrittsöffnung (4) zusammenwirkt und der mittels einer Ventilspindel (6) mit einer Arbeitsmembran (7) verbunden ist, mit einem Gasmangel-Schließteller (12), der der Durchtrittsöffnung (4) axial verschiebbar zugeordnet ist und der von einem Federelement (14) in Offenstellung gehalten wird. Der Gasmangel-Schließteller (12) wird von einem Gasstrom-Führungsring (16) umgeben, der einen rohrförmigen Strömungsweg (15) für das Gas bildet, wobei sich der Gasstrom-Führungsring (16) in Achsrichtung von der Durchtrittsöffnung (4) bis über den Gasmangel-Schließtellers (12) hinweg erstreckt und wobei die Federkraft des Federelements (14) in Abhängigkeit von einem oberen Grenzwert des Durchflusses festgelegt ist.
摘要:
The inventive device consists of a housing arrangement (1) comprising a housing body (2), a housing neck (3) and a housing head (4). Two respective recesses (7) starting from each front side of the inner wall of the housing (2) are provided to accommodate holders (8) for a total of four ultrasonic transducers (6). Connecting lines (15) pertaining thereto run from the recesses (7) through a front-face groove (9) to a chamber (10) extending from the corresponding front face, whereupon said connecting lines (15) lead to pressure lines (16) disposed in the neck of the housing (3) between the chambers (10) and the interior of the head of the housing (4). A sealing o-ring joint (12) extends radially outside said recesses (7), grooves (9) and corresponding chambers (10). A disc-shaped flange (13) that is screwed to the housing arrangement (1) tenses the o-ring joint (12).
摘要:
Die Resonanzerscheinungen werden stromab eines Abrißbereiches eines umströmten Körpers (1) durch Wirbelablösung verursacht. Zur Verminderung der Resonanzerscheinungen wird über der Länge des Abrißbereichs des umströmten Körpers (1) eine Mehrzahl von Karmanschen Wirbelstraßen (4,5) erzeugt, wobei benachbarte Wirbelstraßen gegeneinander phasenverschoben sind. Dies führt zu einer starken Dissipation der Wirbel untereinander und folglich zu einer Verminderung der Resonanzerscheinungen
