Subject: variable restriction to the flow/ is forced against an expansion disk/ as a combine element gen. Дорогие форумчане!
Есть такой контекст, сложно определиться с формулировкой следующих выражений:
variable restriction to the flow/ is forced against an expansion disk/ as a combine elementA pressure regulator includes a restricting element, a loading element, and a measuring element:
The restricting element is a type of valve. It can be a globe valve, butterfly valve, poppet valve, or any other type of valve that is capable of operating as a variable restriction to the flow. (перевела как "Это может быть запорный клапан, поворотный затвор, тарельчатый клапан, или любой другой тип клапана, который способен выступать ограничителем переменного потока.")
The loading element applies the needed force to the restricting element. It can be any number of things such as a weight, a spring, a piston actuator, or more commonly the diaphragm actuator in combination with a spring.
When the actuator is forced against an expansion disk (не понимаю как перевести и не нашла что такое expansion disk), the force is distributed among the pressure walls. This allows the gas to flow at the proper rate and not to be continually vaporized and diluted.
The measuring element determines when the inlet flow is equal to the outlet flow. The diaphragm is often used as a measuring element because it can also serve as a combine element (моя тоже не понимать что за комбинирующий элемент). Может у кого-то встречалось?
заранее спасибо!
