摘要： The closing and sealing means for use in air admittance valves includes a valve housing (10) designed to be connected to the waste water pipe system, an upper cap (14) and valve closing and sealing means consisting of a fixed valve seat (22) and a movable closing member (24). The housing (10) includes at least one passageway (16) in communication with the surrounding atmospheric air, and at least one passageway (18) in connection with the inner space (19) of the sewage system, each of said passageways being in contact with the movable closing member (24). The closing means comprise a rigid movable closing member in the shape of a poppet valve (40) having an inverted bowl shaped central part (42) provided, at its periphery, with an inverse angled conical surface (44) extending upwards and designed to co¬ operate with the sealing means consisting of a fixed valve seat (22) having an upper edge provided with a soft annular seat (50) presenting a thin annular cantilever lip (52) extending towards the centre of the seat (22).

摘要： The drain system in a building is divided in at least two parts, namely a first part (2) arranged to receive drain water contaminated to a relatively high degree from one or a plurality of first units (3), and a second part (10) arranged to receive drain water normally contaminated to a lower degree from one or a plurality of second units (11, 12). The second drain system part (10) comprises at least one drain conduit (13) and at least one unit (11) connected thereto and so constructed that it lacks traps preventing a flow of air therethrough. An apparatus (16) is connected to said drain conduit (13), for generating such a negative pressure in said drain conduit giving rise to an evacuating flow of air from the room in question in said building through said at least one unit (11) and through said drain conduit (13).

摘要： A heated ultrasonic treating device (6) comprising a sump (13) through which suspended matter-containing liquid passes, a temperature-controllable heater (14) disposes in the sump (13), and a ultrasonic vibrator (15) disposed in the sump (13). The heated ultrasonic treating device (6) uses the ultrasonic vibrator (15) to apply ultrasonic waves while heating organic drain passing the sump (13) with the heater (14), thereby pulverizing suspended matters and reducing the amount of SS. In addition, a treating column, where pulverized suspended matter-containing liquid is aerobically treated by aerobic microorganisms, is prevented from efficiency lowering due to clogging.

摘要： Die Erfindung betrifft ein Rohrleitungssystem (1), abschnittsweise gebildet aus miteinander verbindbaren Rohrstücken (2) und/oder Formstücken und/oder Verbindungsstücken, aus denen der jeweils benötigte Verlauf des Rohrleitungssystems (1) zusammensetzbar ist, wobei die Rohrstücke (2) und/oder Formstücke und/oder Verbindungsstücke einen senkrecht zur Fließrichtung des Abwassers (5) im wesentlichen nicht-kreissymmetrischen Querschnitt aufweisen. Ein derartiges Rohrleitungssystem (1) kann zur Abführung von innerhalb eines Gebäudes anfallenden Abwässern in Gebäudeinstallationen dienen und derart an Montageflächen (6) befestigbar sein, daß die Rohrstücke (2) und/oder Formstücke und/oder Verbindungsstücke weniger weit von Montageflächen (6) hervorkragen als hydraulisch äquivalent dimensionierte Rohrleitungssysteme kreissymmetrischen Querschnittes. Dadurch kann es auch zur geschoßweisen Entwässerung von Gebäuden (27) Verwendung finden. Das Rohrleitungssystem (1) kann dabei auf oder an den Außenmauern (6) von Gebäuden (27) montiert werden, indem es innerhalb von Dämmschichten (10) auf der Außenmauer (12) von Gebäuden (27) eingebracht wird und daher auch optisch nicht auffällig verläuft.

摘要： The invention relates to a valve for admitting atmospheric air into the waste pipe system in response to a pressure reduction in the system and for preventing discharge of contaminated air from the waste pipe system to the atmosphere. The valve consists of a valve body having at least two air inlet openings (30) in connection with the atmospheric air, each of the openings (30) alternating with a passage (14) towards the waste pipe system, said openings and passages (14) being equally distributed within the valve housing when considering a cross sectional view in a horizontal plane about the valve seat level (H). The valve member (34) resting, in normal closed position, on a the valve seat (24) separating said openings (30) from said passages (14) and having a substantially butterfly shaped sealing surface in case of a valve embodiment having two diametrically opposed openings (30) situated perpendicular to respectively two diametrically opposed passages (14)

摘要： A system for controlling fluid flow between a first point and a second point on a fluid line is disclosed. The system includes the first valve located at the first point on the fluid line to permit forward fluid flow from the first point to the second point on the fluid line and for closing to prevent such forward fluid flow. The system also includes flow sensors for detecting forward fluid flow at the second point and opening the first valve when such forward fluid flow is detected. The flow sensors also close the first valve when fluid flow at the second point stops. The system further includes a second valve located at the second point for opening and closing to control forward fluid flow at the second point. The system prevents forward fluid flow if a break in the fluid line occurs between the first and second points by preventing the first valve from opening. The first valve is prevented from opening since forward fluid flow cannot occur at the second point when the second valve is opened if a depressurizing break in the fluid line has occurred.
