The shut-off valve (10) has a pipe section (11) with a gap-like opening penetrating the pipe wall. Guides aligned transverse to the flow direction are attached at the opening. The pipe section is formed of plastic and a sleeve hold a sealing between itself and the pipe inner wall. The...
Valve with a closed in the inflow direction, at the end of a rod arranged shut-off memberMARTIN EBERT,DIPL.-ING.
The article discusses the installation of an EZ-2 insertion valve by Advanced Valve Technologies LLC (AVT) at a water main that ruptured in Wyoming, Michigan. It states that the city's water repair crew were unable to repair the ruptured... ED Nunes - 《Waterworld》 被引量: 0发表: 2013...
Shut-off device for a gate valve with an alternating pressure acting on the direction ofHARTMANN ALFONS DIPL-ING, DE
The hydraulic control valve unit to control a hydraulic lifting device includes a control valve (4) and flow regulator (20). A pressure signal acting in the direction of the shut-off position of the flow regulator is influenced by means of a splitter which has a first restrictor installed ...
A shut-off valve (6) is disposed in the pipeline in flow direction upstream of the outlet port of the cylinder and is constructed in a form of a two-port rotary gate valve. An independent claim is also included for a method of conveying a viscous material....
Coupling for shut-off valve with the inner rotatable deflecting element for the maintenance of the direction of the forward flowFRACCHIA, STEFANO, BOFFALORA TICINO MI, IT
A shut-off valve (6) is disposed in the pipeline in flow direction upstream of the outlet port of the cylinder and is constructed in a form of a two-port rotary gate valve. An independent claim is also included for a method of conveying a viscous material....
Each valve is connected from one DC terminal to one AC terminal which is similar to the two-level converter. However, in MMC, each valve has a controllable voltage source and own storage capacitor. Every SM is consists of two series connected IGBTs across the capacitor. The common point is...
