When the flow through the balance of the piston damping the flow of holes increases, the balance of the piston, the next increase in pressure on both sides of a balanced increase in the distance the piston increases, and vice versa reduced; and also because the spring stiffness is very small, so that shift the balance of the piston pressure required very few changes, so the flow through the Poppet head is not much change, so the first opening Poppet very few changes, to mention the pressure of moving the first opening can be said to remain unchanged, that is, when the pilot valve spring after a set, Poppet Head was opened, the balance piston chamber pressure remained basically unchanged.

当流经平衡活塞上阻尼孔的流量增加时，平衡活塞上、下两侧的压差增加，平衡活塞上升距离增加，反之则减小；又因为弹簧的刚度很小，使平衡活塞上移所需压差变化很小，所以通过提动头的流量变化也不大，因此提动头的开口变化很小，提动头开启的压力可以说是不变的，亦即当先导阀的弹簧一经设定后，提动头被打开时的平衡活塞上腔的压力基本保持不变。

Media Help Everyday we are exposed to the steam often divided into two, one, the boiler steam - saturated steam 2, thermal power plants out of steam - superheated steam 1, a relatively stable temperature and pressure saturated steam, temperature lower than 250 ℃, working pressure lower than 1.6Mpa 2, superheated steam temperature and pressure changes of a high base temperature up to 400 ℃, working pressure is lower than 4.0Mpa For the first steam, we usually use soft sealing steam solenoid valve as follows: Structural characteristics This valve is a valve and Balance valves main valve by the two vice components with the second open valve Pilot solenoid valve Heat: electromagnetic part, some with special high temperature seals and sealing materials, electrical materials, and apply a variety of insulation measures Wear: selection and reasonable Globe Valves guidance suite valve cup and clever use of fluid lubrication, reduce wear, increase life expectancy Resistance to condensation: condensation of steam pipeline valve on the steam water is an important factor in action, the valve will not affect the condensation water Other uses - soft sealing steam solenoid valve This series solenoid valve can Safety valves be widely used in textile, printing, chemicals, plastics, rubber, pharmaceutical, food, building materials, machinery, electronics, surface treatment and research sectors and bathroom, dining room, air conditioning automatic control system.

介质说明日常生活中我们接触到的蒸汽常分为两种，1、锅炉蒸汽-饱和蒸汽 2、热电厂出来的蒸汽-过热蒸汽 1、饱和蒸汽温度压力相对稳定，电动阀门执行器温度低于250℃，工作压力低于1.6Mpa 2、过热蒸汽温度压力变化基数较大温度最高可达400℃以上，工作压力则低于4.0Mpa 对于第一种蒸汽，我们通常会选用氧气专用阀、铜阀门软密封的蒸汽电磁阀如下：结构特点本阀是由副阀和主阀两大部件构成的先导式二次开阀的电磁阀耐热：电磁部分、密封件部分用特种耐高温电工材料和密封材料，并应用了各种隔热措施耐磨：选材合理，电站阀门阀杯和导向套间巧妙地利用流体的润滑作用，减少磨损，提高寿命耐冷凝：蒸汽管道的冷凝水是影响蒸汽电磁阀动作的重要因素，本阀则不受冷凝水影响其他用途-软密封蒸汽电磁阀本系列电磁阀还可广泛地应用平衡阀纺织、印刷、化工、塑料、橡胶、制药、食品、建材、机械、电器、表面处理和科研部门以及浴室、食堂、空调等自控系统。

In the course of China's becoming a semi-colonial,semi-feudal society .The compradors were the forerunners of Chinese bourgeoisie ,and the same time ,used to play a pole of a bridge for the Western countries-economy invasion .But each new things has existent reason ,promoting Chinese economy modernization ;the profundity of their influences on Chinese social relationship's changes.

在中国社会半殖民地，半封建化的过程中，买办曾经是中国资产阶级的先导，是西方资本主义在华进行经济活动的桥梁，但任何新生事物都有其存在的合理性，它促进了中国经济的近代化，也对中国的社会关系的变动，有不容忽视的影响。

Spring-loaded safety valve spring is delivered to the valve on the container or force to balance the pipeline pressure by adjusting the elastic springs to balance the medium on the pressure valve control media pressure to achieve the objective of safety valve lever weights Is to use a heavy hammer through the transmission lever to force the valve to balance the pipe or container medium pressure by adjusting the weights of the valve to balance the role of media from the valve on the pressure, media pressure to achieve the purpose of control ; Pilot of the main safety valve by valve components and sub-valve, to promote the role of Vice valve main valve action, also known as the pulse safety valve.

弹簧式安全阀是利用弹簧传递到阀瓣上的作用力来平衡容器或管道内压，通过调节弹簧的松紧来平衡介质对阀瓣的压力从而达到控制介质压力的目的；杠杆重锤式安全阀是利用重锤通过杠杆传递到阀瓣上的作用力来平衡管道或容器内介质的压力，通过调整重锤对阀瓣的作用距离来平衡介质对阀瓣的压力，从而达到控制介质压力的目的；先导式安全阀是由主阀和副阀组成，借副阀的作用带动主阀动作，又称为脉冲式安全阀。
