英国进口25P斯派莎克蒸汽减压阀（价格行情）
25P斯派莎克蒸汽减压阀的设计制造完全依据使用者的需求，其多元化的组合在工业界没有任何其他的减压阀可与之媲美。为了实现多目标控制设备的独立性和经济性，可在同一个主阀上组合多种控制，无论是温度控制、压力调节还是二者在一起，都能做到反应迅速、控制精确、安全可靠。同时，25P系列减压阀的所有零件均能够分解检查或保养，而无需移动管路中的主阀体。正确的选型和安装保养，更能保证其长期无故障的工作。
25P Spirax Sarco steam valve designed and manufactured entirely in accordance with the needs of the users, and its diversified portfolio in the industry, no other valve can be compared. In order to achieve multi-objective control device independence and economy, in combination with a variety of main valve control, whether it is temperature control, pressure control, or both together, can achieve rapid response, precise control, safe and reliable . Meanwhile, 25P series valve can be decomposed, all parts are inspected or serviced, without moving the main valve in the pipeline. Proper selection and installation and maintenance, to better ensure its long-term trouble-free operation.
工作原理
启动前导阀弹簧处于自由状态时，主阀和导阀处于关闭状态。导阀有弹簧力作用打开，蒸汽经由导阀进入主隔膜室，一部分蒸汽则经由控制孔流出，当导阀流入的蒸汽大于由控制孔流出的蒸汽，主隔膜阀中的控制压力增大，打开主阀。随着蒸汽流过主阀，下游压力的增量经由感应管反馈，作用在导阀隔膜下，平衡隔膜上部的弹簧压力，使导阀组建关闭节流，维持主隔膜中的压力，控制主阀开度输送适量的蒸汽。调节导阀隔膜上的弹簧即可改变下游压力。
Start a leading valve spring is in a free state, the main valve and pilot valve is turned off . The spring force of the pilot valve open , the steam through the pilot valve into the main diaphragm chamber , the portion of the steam flow through the control hole , the inflow of steam when the pilot valve hole is greater than the steam flowing out from the control , the control of the main diaphragm pressure, open main valve . As the steam flows through the main valve , the downstream pressure increase feedback via the sensing tube , acting on the pilot valve diaphragm , the balance of the upper diaphragm spring pressure , so that the formation of the pilot valve closed throttle , to maintain the pressure in the main diaphragm , to control the main valve the amount of opening of the steam delivery . Regulating pilot valve diaphragm spring to change the downstream pressure .
主要特征
1、导阀弹簧：三种颜色的弹簧，可提供从0.2-14bar g范围内不同压力的准确控制。
2、温度调节刻度盘：快速准确的设定所需温度。
3、温度感应器：在温控元件中有无需补偿的液体，感应瞬时温度的变化，提供准确的控制。
4、百分之百的测试：每一个25P系列的减压阀在出厂前都经蒸汽测试，以确保无故障的操作。
1, the pilot valve spring : spring three colors , is available from the range of 0.2-14bar g accurate control of different pressures .
2 , the temperature adjustment dial : set the desired temperature quickly and accurately .
3, the temperature sensor: the temperature control devices have no compensation liquid sensing the instantaneous temperature changes, providing accurate control.
4 , one hundred percent of the test : Each 25P series valve steam in the factory have been tested to ensure trouble-free operation.
