White Paper: The Use of a Flow Limiter in Propellant Feedlines During A Priming Event

Posted on Aug 9, 2018 in News & Events, White Papers |

Published on: August 8, 2018 By: Valcor Aerospace The Use of a Flow Limiter in Propellant Feedlines During A Priming Event Vitor Cardoso – Assistant Chief Engineer, Aerospace Products Richard Kelly – Senior Project Engineer, Aerospace Products Yuri Gerasimov – Chief Engineer, Aerospace Products Merritt D’Elia – Design Engineer, Aerospace Products Sumeet Kapur – Design Engineer, Aerospace Products Eli Vasquez – Design Engineer, Aerospace Products Tim Monahan – Design Engineer, Aerospace Products Abstract High pressure spikes typically occur within propellant feedlines during a priming event. Such an event occurs when a pyro valve, or latch valve opens, allowing liquid propellant to fill the downstream lines, which are at vacuum conditions. These spikes are the result of high velocity propellant flowing into a dead-ended line (closed valve). The impact of the column of liquid propellant hitting the closed valve creates a compression wave, also referred to as “Water Hammer”. This priming event is a well known phenomenon that has been much studied and analyzed. Pressure spikes may be reduced if a blanket of low pressure gas is intentionally trapped within the lines. The drawback to this approach is that the compression of the gas may create significant heat due to adiabatic compression. This may lead to detonation of the propellant. Another solution is to install a fixed flow restriction in the line, which will decrease the liquid impact velocity, thus reducing the water hammer. The drawback to this approach is that the system will suffer from a pressure loss during normal flow usage. This paper will discuss a new approach, which will be to install a flow limiter in the propellant line. Such a device would sense an abnormally high flow, and close a poppet so that the orifice size is reduced. This would limit the flow velocity, thus reducing the pressure surge. The poppet would then return to its full open position during nominal flow, thus not producing any excess pressure drop during normal operation. The pressure and velocity during a priming event, with the proposed flow limiting device, will be calculated using well established numerical methods. These results will be compared to similar analysis results for priming events for systems which use fixed restrictions and no restrictions. It will be shown that the use of a flow limiter is a very attractive option. Introduction During the priming of a spacecraft propulsion system, the filling of an evacuated pipeline can generate severe waterhammer spikes due to the column of liquid impacting a closed thruster valve. A severe example of this occurred on the Compton Gamma Ray Observatory, on April 7, 19911. During this mission fluid components downstream were damaged during the priming event. Once in orbit an isolation valve...

Valcor Acquires Rights to Manufacture and Sell CU Services Products

Posted on Aug 1, 2018 in News & Events, Product News |

Published on: August 1, 2018 By: Valcor Nuclear Valcor Engineering, a designer and manufacturer of solenoid valves and flow control components for liquids and gases, is proud to announce they have acquired the rights to manufacture and sell CU Services products. CU Services has been providing products to the power and process industries for over forty-five years. Their line of products include: plug resistant orifices to drain steam and condensate lines in power and process plants, diffusers for high pressure drop service, diffuser silencers for high pressure service as well as multistage let-down orifices. “This will allow Valcor to provide consultation and replacement components to legacy products, as well as the ability to supply unique solutions in critical applications in the power and process industries,” stated Steven Gatcomb, Nuclear Sales & Marketing Director. CU Services orifices have been used in power plants and process applications around the world since 1971, and were designed to prevent inadvertent water induction into turbine cylinders by replacing failure-prone steam traps. Diffusers are made for pump spillback and flow restriction to eliminate the damage that is caused by control valve cavitation. Silencers greatly reduce steam vent noise and creates a back pressure on the vent valve to reduce the wear and tear on the valve. About Valcor Valcor Engineering Corporation (www.valcor.com), founded in 1951, designs and manufactures solenoid valves and control components for liquids and gases in critical applications in the aerospace, nuclear, light industrial and scientific industries. Headquartered in Springfield, New Jersey, Valcor’s world-class staff of engineers, designers, and technical support personnel utilize fully-equipped, modern test facilities to test the most precise and exacting standards. With a library of more than 18,000 designs, Valcor’s design team can modify existing technology to suit practically every hard to handle application.
