  1. When the system pressure drops to the return pressure, the security valve will be closed and stop discharging, in the way of which the pipelines and equipments of the steam system will be protected

    當系統運行壓力降低至安全閥的回座壓力時，主蒸汽安全閥自行關閉，停止排放，從而對主蒸汽系統的管道和設備起安全保護作用。
  2. When a reducing valve is used, it makes a closed system ; therefore, a pressure relief valve must be installed in the downstream side of the regulator to protect equipment against excess pressure which is built up by the expansion of water from the domestic hot water supply tank or heater

    如果採用減壓閥，將形成一個封閉系統；因此必須在調節閥的下游位置安裝一個壓力安全閥，以保護設備不會由於室內熱水供應容器或熱水器造成的水膨脹而變得壓力過大。
  3. This paper analyses the type, function and characteristics of usual proportional control valves and raises a new modificative version in the light of their drawback. that is, basing on the principle of flow amplification and electrical feedback and throughout calculation and analysis on flow closed loop control and pressure flow combination., determination of the minimum controlled pressure difference as well as flow controlling range and structure of main valve and research of the dynamic and static characteristic, the paper puts forward control principle of " flow - load pressure change - displacement revision " and pressure / flow double closed loop, and further expounds that using a proportional controller and a electric mechanical transducer can separately serve the control function of pressure or flow as well as flow pressure combination

    本論文分析了目前常用比例閥的類型、功能、特性，並針對其不足提出新的改進方案，即：以流量放大，電反饋兩個原理為基礎，通過對流量閉環控制及壓力流量復合的計算分析、確定上最小控制壓差及流量控制范圍，確定主閥結構、功能特性研究等，提出了「流量? ?負載壓力變化? ?位移修正」的控制原理和壓力流量雙閉環控制原理，並進一步論述了利用一個比例控制器和一個「電?機械轉換器」就可完成獨立的壓力或流量控制功能以及流量壓力復合控制功能。
  4. If flow rate is in excess of that specified, turn indicator towards closed position, noting pressure drop and valve setting and determining new flow rates from flow rate chart

    如果流量超過規定，將指示器旋轉到關閉位置，注意壓降和閥門設置，並從流量表中確定新的流量。
  5. If flow rate is in excess of that specified, turn indicator knob towards closed position, noting pressure drop and valve setting and determining new flow rates from flow rate chart

    如果流量超過規定，將指示器旋鈕旋轉到關閉位置，注意壓降和閥門設置，並從流量表中確定新的流量。
