A plug for closing an opening in the sidewall of a pipe, including a base member having a radial flange portion, a tubular portion and an annular elastomeric seal member slideably received on the base member tubular portion and in engagement with the flange portion. A rigid compression member is slideably received on the base member tubular portion and in contact with the elastomeric member and has a frusto-conical circumferential surface. A plurality of rigid segmented slips are received on the...

The invention relates to a backflow preventer (1) integrateable into a gas or liquid pipeline (2). The inventive backflow preventer consists of a closing body (3) which is embodied in the form of a hollow body which is open on a drainage side thereof and defines a passage channel (5) between itself and the central counterpart (4) opposite thereto. Said closing body (3) is displaceable by a flow medium flowing through the passage channel (5) in a flow direction (Pf 1) from a sealing contact there...

Disclosed is a method and system for converting or retrofitting manually-operated flush valves. A conversion system for converting an installed manually-operated flush valve includes a power module, a control module, and a driver module mechanically coupled to a manual handle to externally activate the converted flush valve.

A fluid leak detection system includes a sensor, a control module and a valve module. The sensor is adapted to be placed near a fluid source, such as a water supply line of an appliance. The valve module advantageously includes a motorized ball valve or a magnetic latch configured to arrest fluid flow through a supply line. The control module actuates the valve module and an audible alarm when the sensor detects a fluid leak. The valve module closes a valve positioned along the water line to res...

A water faucet includes a lower upright pipe integrally formed by a working process, and an upper upright pipe mounted on an upper portion of the lower upright pipe and formed by cutting a hollow pipe. Thus, the upper upright pipe is formed directly by cutting a hollow pipe, so that the upper upright pipe is made easily and rapidly, thereby decreasing the costs of fabrication, shortening the manufacturing time, simplifying the working process, and enhancing the working efficiency.

A non-return device (10) comprises a flat silicone rubber tubing (50) defining a pair of walls (70, 90) which separate to admit fluid in a forward direction but remain together to block fluid flow in a reverse direction. A tubular body (30) surrounds the tubing (50) and comprises an off-set outlet (34) to provide an uninterrupted fluid flow surface for use in a non-vertical orientation. The tubing (50) is mounted on a cartridge (130) which moves axially within the tubular body and compresses the...

The invention relates to a valve rotating device comprising a basic body, a cover which is rotatable and axially displaceable relative to the basic body about an axis of rotation, and a rotating device to rotate the basic body relative to the cover about the axis of rotation. In accordance with the invention an increased service life is achieved in that the rotating device has a freewheel which is in operative connection with the cover on the one hand and the basic body on the other hand. In one...

A valve position indicator is directly coupled to a valve shaft. The indicator has a gauge that directly indicates rotation of a valve shaft in a subterranean valve.

A surge prevention valve may be used to prevent the formation of an initial surge of high pressure. The valve may be located, for example, between a high pressure gas cylinder and a medical pressure regulator. The valve is provided with first and second valves located within a housing and integrating a pressurization orifice. The initial opening of the valve in an axial direction enables gas to flow through the pressurization orifice at a first flow rate. The full opening of the valve in the axi...

An apparatus to aid in the holding and retention of tubing or cables used on patients in a hospital environment is disclosed. The invention is envisioned to be used on intravenous tubing, air tubing, sensor cables and the like. The invention would comprise a clamshell-like case with the approximate dimensions of two inches high, three inches wide and approximately eight inches long. When opened, a series of "S"-shaped grooves along with one that is straight and routed through the center of the c...
