VALVESEXTREME value theoryWATER pipelinesIn order to explore the influence of different types of valves on shutdown characteristics of delivery system, this paper builds a 3D CFD numerical simulation model including centrifugal pump, outlet valves and pipelines with the dynamic mesh and...
Finally, if flow matters more than looks, use two full-bore lever valves in place of a mixing valve, one on the hot and one on the cold. Tee them together and use a fixed shower head with enlarged holes. It may not be pretty but it will be quiet, reliable, have good flow rates ...
aluminium and stainless steel quick coupling, double-way and treble-way valves, medium and low pressure petrochemical valves,European standard gas recovery tanker parts, gas station recovery products. Our products are widely supplied for industries like petroleum com...
aThe design and material of fittings for gaseous oxygen such as safety shut-off valves, control devices and non return valves shall be suitable for oxygen at the intended pressures and temperatures. 配件设计和材料为气体氧气例如安全停机阀、控制设备和非回归阀门为氧气将是适当的在意欲的压力和温度。[...
Free Float® and lever float steam traps are the only types of trap that constantly contain both steam and condensate in the body. Since steam is always present, these models are suitable for service in freezing conditions, provided that the discharge drains to atmosphere and that the body do...
The pressure, instantaneous, and cumulative gas production of each simulation layer are recorded regularly basis once valves 4 and 5 are opened to realize the synchronous gas production of two simulation layers. (3) In view of the difference of reservoir pressure and physical properties in co-...
Three small-break loss-of-coolant accident (SBLOCA) tests with safety injection pumps were carried out using the integral-effect test loop for SMART (System-integrated Modular Advanced ReacTor), i.e., the SMART-ITL facility. The types of break are a safety injection system line break, shutdo...
A communication/service zone (26), separated from the fuel tank chambers by a dense intermediate wall, can be accessed from the outside, with the functional connections for the fuel filling pumps, remote filling line (19), filling connections, shut-off valves, the electrical system and the ...
The test follows rinsing of the color changer (1) in the interim phases between the individual varnishing phases. Compressed air is admitted to the varnish (8) and rinsing (11) supply lines in the flow direction behind varnish valves and before the rinsing valves and main atomizing valve (19...
The drive system consists of several motor-pumps that can supply energy to each actuator individually, whereas the valve matrix is composed of several on–off valves. The motor-pump can drive an actuator on the condition that the corresponding valve in the valve matrix is open. The ...
