主要技術參數及性能 Main technical parameters and performance

啟動前正常的位置是主閥關閉，而導閥則由彈簧作用力打開.蒸汽由導閥經壓力控制管進入主閥隔膜室，部分蒸汽則由控制孔流向下游.施加在主閥隔膜上的控制壓力增大，打開主閥  RETZ The normal position before startup is that the main valve is closed, while the pilot valve is opened by the spring force. The steam enters the main valve diaphragm chamber through the pressure control pipe from the pilot valve, and part of the steam flows downstream through the control hole. The control pressure applied to the main valve diaphragm increases, and the main valve is opened

隨著蒸汽流過主閥.下游壓力上升，并由下游壓力感應管反饋作用在導閥隔膜的下部（為了確保下游壓力的穩定，應安裝下游壓力感應管），該作用力使導閥逐漸節流關小，與隔膜上部的彈簧作用力相平衡，從而維持主閥隔膜室內的壓力，控制主閥的開度，輸送適量的蒸汽，維持下游穩定的壓力.當下游壓力上升時，反饋壓力增大，導閥關閉，主隔膜室的壓力從控制孔釋放，使主閥緊密關閉 RETZ As the steam flows through the main valve The downstream pressure rises and is fed back to the lower part of the diaphragm of the pilot valve by the downstream pressure sensing pipe (in order to ensure the stability of the downstream pressure, the downstream pressure sensing pipe shall be installed). This force causes the pilot valve to gradually throttle and close down, which is balanced with the spring force on the upper part of the diaphragm, so as to maintain the pressure in the diaphragm chamber of the main valve, control the opening of the main valve, deliver an appropriate amount of steam, and maintain the stable downstream pressure When the downstream pressure rises, the feedback pressure increases, the pilot valve closes, and the pressure of the main diaphragm chamber is released from the control hole to close the main valve tightly

下游任何的負載變化或壓力的波動，都會反饋在導閥隔膜的下方，從而調節主閥的開度，確保下游壓力的準確穩定 Any load change or pressure fluctuation in the downstream will be fed back to the lower part of the pilot valve diaphragm, so as to adjust the opening of the main valve and ensure the accuracy and stability of the downstream pressure

飽和蒸汽  Saturated steam

例；蒸汽流量為600kg/h，壓力從6bar減至4bar。在表中找到上游壓力為6bar的曲線和下游壓力為4bar的交點，從該點垂直身下，找到所有系列口徑的容量。在該列中DN32的閥是能滿足要求的最小口徑閥 Example; The steam flow is 600kg / h and the pressure is reduced from 6bar to 4bar. In the table, find the intersection of the curve with the upstream pressure of 6 bar and the curve with the downstream pressure of 4 bar. From this point, find the capacity of all series of calibers. In this column, DN32 valve is the minimum diameter valve that can meet the requirements

過熱蒸汽 Superheated steam

由于過熱蒸汽比容較大，圖中給出的值應乘以修正系數，若過熱度為55℃，則修正系數為0.95，若過熱度為100℃，修正系數為0.9，用于上述例子，若蒸汽過熱度為55℃，則DN32口徑的減壓閥流通能力為740X0.95=703kg/h，仍能滿足600kg/h的負載要求，則DN32 的閥仍適用 Since the specific capacity of superheated steam is large, the value given in the figure should be multiplied by the correction factor. If the superheat is 55 ℃, the correction factor is 0.95; if the superheat is 100 ℃, the correction factor is 0.9. For the above example, if the superheat is 55 ℃, the flow capacity of the DN32 pressure reducing valve is 740x0.95 = 703kg / h, which can still meet the load requirement of 600kg / h, then the DN32 valve is still applicable
