摘要:
A valve assembly (10) is to be used in conjunction with a tubular member having an internal surface surrounding a passage into which the valve assembly is to be sealingly inserted. The valve assembly includes a tubular body (25) having a longitudinal passage and an outer surface to be located adjacent the internal surface. A seal (29) is mounted on the outer surface to engage the internal surface to sealingly connect the tubular body with the tubular member. A movable valve member (33) is movable between an open position providing for the flow of water from an upstream end to a downstream end of the passage of the tubular body and a closed position closing the passage. Resilient means, such as a spring (34) urges the valve member to the closed position. The resilient means is configured to provide for displacement of the valve member toward the open position when pressure beyond a predetermined pressure is applied upon the movable valve member.

Die Erfindung betrifft eine Wasserablaufvorrichtung (100) für eine sanitäre Anlage, wie einen bodenebenen Duschplatz, umfassend - ein wannenförmiges Wasserablaufelement (3), welches strömungstechnisch mit einem Ablaufrohr verbunden oder verbindbar ist; - eine in das Wasserablaufelement (3) eingesetzte Rinnenabdeckung (4), die im montierten Zustand das Wasserablaufelement (3) nach oben hin abdeckt, wobei in oder an der Rinnenabdeckung mindestens eine Öffnung zur Einleitung von Abwasser in das Wasserablaufelement (3) verbleibt; - wenigstens eine Höhenverstelleinrichtung (10.1) für die Rinnenabdeckung (4), umfassend ein Fußteil (2) und ein gegenüber dem Fußteil (2) höhenverstellbares Kopfteil. Das Kopfteil weist ein zur Rinnenabdeckung (4) kompatibles, dem Fußteil (2) abgewandtes Auflageelement auf, welches mit der Rinnenabdeckung (4) kraft- oder formschlüssig verbunden ist, - wobei das Wasserablaufelement (3) wenigstens eine Vertiefung (6) aufweist, an der sich das Fußteil (2) lose abstützt, - und wobei die gesamte Höhenverstelleinrichtung (10.1) mit der Rinnenabdeckung (4) gemeinsam aus dem rinnenförmigen Wasserablaufelement (3) entnehmbar und in das Wasserablaufelement (3) einsetzbar ist.
摘要:
Ablaufbauteil mit einer Oberfläche, die im eingebauten Zustand des Ablaufbauteils zumindest teilweise mit einer oder mehreren Schichten eines Bodenaufbaus in Berührung kommen kann, wobei an der Oberfläche des Ablaufbauteils zumindest abschnittsweise Verbindungsmittel für die Verbindung mit einer oder mehreren Schichten des Bodenaufbaus angeordnet sind. Die Verbindungsmittel können dabei als von der Oberfläche abragende Verbindungselemente (7) ausgebildet sein, oder alternativ in Form einer Beflockung der Oberfläche bzw. einem daran angebrachtem Flies vorliegen. Das Ablaufbauteil kann beispielsweise einen rohrförmigen Abschnitt (1) und einen Flansch (2) umfassen, der sich von dem rohrförmigen Abschnitt (1) nach außen erstreckt, wobei die Verbindungselemente an der in Einbaulage unteren Seite (6) des Flansches (2) zur formschlüssigen Verbindung mit einer Estrichschicht des Bodenaufbaus angeordnet sind.

The invention relates to a drain, comprising: - a container with a bottom surface and an upright edge along the periphery of the bottom surface; - a discharge opening arranged in the bottom surface of the container; - an adjusting frame placed on the container and having adjusting means for adjusting the height of the top side of the adjusting frame; wherein the adjusting frame fits within the upright edge and the adjusting frame is manufactured from strip material.
摘要:
An apparatus for preventing reverse flows in a drainage is disclosed. In this apparatus, a floating device (41) and a reverse flow preventing device (54) act mutually in opposite directions owing to the floating force and the water pressure, and thus the bottom of the round body (20) of the apparatus is automatically opened and closed, so that the drainage can efficiently work, and the waste water and the draining water with foul odors can be prevented from flowing reversely. The apparatus for preventing reverse flows of waste water according to the present invention includes a round body (20) to be installed in a drain hole (60). A guide member (30) is installed on a second filtering net (25) of the top of the round body (20), and has a guide (31) at the center of it. An openable/closable device actuating member (40) is insertingly installed on the guide member (30), for moving up and down along the guide (31) owing to the floating force and the self-gravity. An openable/closable member (50) is installed on the guide member (30), for causing an air-tight sealing part to be opened and closed by being oppositely interlocked to the openable/closable device actuating member (40).
摘要:
An improved firestop fitting with a flammable main conduit (11) and extension conduit (12) supporting a non-flam mable sleeve (14) and plug (16). The plug lodges into the sleeve when a harness (17) is melted by heat from a fire below the floor (100 or 101) in which the fitting is mounted which passes into the conduits. The fitting is relatively light and inexpen sive.
摘要:
A floor drain or some other cup-shaped water seal, comprising a cupped body (1), a superstructure including a trash screen (2). a water seal forming wall (3), and an outlet (4) for a sewer pipe (5). A problem is to improve the superstructure of a floor drain so as to prevent bacteria from spreading out along moist surface films or membranes. In order to resolve the problem, the superstructure is provided with a funnel-shaped ring (6), which is fitted below trash screen (2) and whose central hole (7) is smaller than said outlet (4) and whose outer rim is tightly (8) sealed to body (1).
