the media normally closed, medium pressure will be reduced, opening the action of electromagnetic valve while the valve after the pressure, so that the pressure valve to keep within a certain range, the import type 6213 two two normally closed solenoid valve pressure change of circumstances, to maintain the set outlet pressure range, subsequent protection of life and production equipment. This type valve should normally be installed horizontally in the pipeline. Type 6213 two two normally closed solenoid valve is a necessary accessory, the main role is air pressure normally closed and stabilization to a fixed value, in order to facilitate the type 6213 two two normally closed solenoid valve to obtain a stable source of power for air normally closed control. Type 6213 two two normally closed solenoid valve by the pressure control valve. When the 6213 type two two normally closed solenoid valve elevated pressure indicator, 6213 type two two normally closed solenoid valve reduces the valve opening; when the detected type 6213 two two normally closed solenoid valve after the pressure normally closed, 6213 type two two normally closed solenoid valve opening increases, in order to meet the control requirements. ASCO solenoid valve coil bottom surface and the high temperature combustion in direct contact with the product, the valve opening period under high temperature (900-1000 ℃) and corrosive gas at high speed (up to 600m/s) scour, valve core temperature up to 700-800 ℃, the valve disc and valve stem transition arc segment, temperature is 600-700 ℃. Thermal deformation of materials. High temperature will make the mechanical properties of metallic materials decreases, thermal deformation of materials. When the valve sealing surface is not strict, will cause the loss of high temperature gas valve. Valve seat, valve and valve seat, the common effect of the inertia force and spring force, but also bear the impact of coital considerable variable load, the valve when the beating or valve gap increases, the load will increase. The valve and valve seat of the impact, easy to form a sealing surface deformation and severe wear. For marine diesel engine most for turbocharged diesel engine, because of the fresh air inlet pressure to prevent the oil from the valve catheter may, therefore, prone to dry friction between the metal. But in general the valve and supercharged diesel engine exhaust valve seat alloy surface with a layer of oil always cloth or oil and lubricants. ASCO solenoid valve and main valve closing body turn upward, open the valve. When the entrance and outlet pressure to start, the power, the electromagnetic force pilot valve, main valve chamber under increased pressure, the chamber pressure drops, thus the use of pressure to push up the main valve; power, the pilot valve with a spring or to medium pressure to promote the closure of parts, moving down, the valve closes. Features: zero pressure or vacuum, high pressure can also be action, but the power is larger, the level required to be installed. Pilot solenoid valve principle: power, the electromagnetic force to open the pilot hole, the chamber pressure to drop rapidly, in close formation around the lower parts of high pressure, fluid pressure to promote the closure of parts moving up, the valve open; power, the spring force of the pilot hole closed, entrance pressure through the bypass hole quickly the chamber is formed under the high pressure low on the valve body in turn around, fluid pressure to promote the closure of parts moving down, close the valve. Features: limit the scope of a high fluid pressure, can be arbitrarily install (need to customize) but must meet the conditions of fluid pressure. Solenoid valve from different and principle of valve structure and materials on, divided into six branch categories: direct acting diaphragm structure, heavy plate structure, step by step pilot film type structure, direct acting piston structure, step by step direct acting piston structure, the pilot piston structure. ASCO solenoid valve coil is mainly composed of a valve seat, the valve (valve) and the loading mechanism three parts. Some of the valve seat and valve body as a whole, some and the valve assembly together, it is connected with the equipment. Often associated with valve stem, it is closely linked to the seat. The above is a disc loading mechanism, the size of the load can be adjusted. When the equipment inside the pressure within the pressure range of certain time, internal medium acting on the valve flap is less than the force above the loading body force added to the valve above, constitutes the difference between the valve and valve seat is the sealing force, squeeze the valve seat, the media can not be discharged equipment. When the equipment inside the pressure exceeds the pressure of work and achieve the type 6213 two two normally closed solenoid valve opening pressure of the internal medium acting on the alarm valve, the force is greater than the loading mechanism is applied on top of it, then leave the seat valve, 6213 type two two normally closed solenoid valve opening, equipment the medium is discharged through the valve seat, if 6213 two two normally closed solenoid valve capacity greater than the device's safety discharge device, pressure is gradually decreased, and the exhaust through a short time later, the pressure is reduced back to normal working pressure. The pressure acting on the valve flap above and below the loading mechanism applied on top of it, the valve and close pressure valve seat, the media to stop discharge, equipment to maintain the normal operating pressure to continue to run. Calibration temperature ASCO solenoid valve coil. Solenoid valve to allow the liquid viscosity generally below 20CST, more than 20CST should be specified. Working pressure, the maximum pressure in the pipeline is less than 0.04MPa should be used in ZS, 2W, ZQDF, ZCM series direct drive type and step and direct action; minimum working pressure is more than 0.04MPa can be selected for the pilot (differential) electromagnetic valve; the maximum working pressure should be less than the maximum rated pressure electromagnetic valve; electromagnetic valve are one-way, so should pay attention to whether the anti pressure, if installed check valve. Fluid cleanliness is not high when the solenoid valve installed before the filter, solenoid valve on the media in general requirements ASCO电磁阀线圈 ASCO电磁阀线圈是采用控制阀体内的启闭的开度来调节介质的常闭，将介质的压力降低，同时借助阀后压力的作用电磁阀的开度，使阀后压力保持在一定范围内，在进口6213型两位两通常闭电磁阀压力不断变化的情况下，保持出口压力在设定的范围内，保护其后的生活生产器具。本类阀门在管道中一般应当水平安装。6213型两位两通常闭电磁阀的一个必备配件，主要作用是将气源的压力常闭并稳定到一个定值，以便于6213型两位两通常闭电磁阀能够获得稳定的气源动力用于常闭控制。6213型两位两通常闭电磁阀的工作由阀后压力进行控制。当6213型两位两通常闭电磁阀门压力指示升高时，6213型两位两通常闭电磁阀阀门开度减小；当检测到6213型两位两通常闭电磁阀后压力常闭，6213型两位两通常闭电磁阀阀门开度增大，以满足控制要求。 ASCO电磁阀线圈底面与高温燃烧产物直接接触，在气阀开启期间还承受着高温（900-1000℃）和具有腐蚀性气体的高速（达600m/s）冲刷，气阀中心温度高达700-800℃，在阀盘与阀杆过渡圆弧中段，温度也有600-700℃。材料发生热变形。过高的温度会使金属材料的机械性能降低，材料发生热变形。当阀面密封不严时，就会引起高温燃气对阀面的烧损。气阀落座时，阀与阀座的惯性力和弹簧作用力的共同作用下，还承受着相当大的冲击性交变载荷，在气阀出现跳动或气阀间隙增大时，这种载荷会明显增加。阀与阀座的撞击，容易形成密封面的变形和严重的磨损。因船用柴油机绝大部分多为增压柴油机，由于进气道内的新鲜空气压力阻止了从气阀导管中获得滑油的可能，因此，金属之间易发生干摩擦。但在一般柴油机的气阀以及增压柴油机的排气阀座合金面间总会布有一层滑油或烟油等润滑物。 ASCO电磁阀线圈和主阀关闭体依次向上提起，阀门打开。当入口与出口达到启动压差时，通电后，电磁力先导小阀，主阀下腔压力上升，上腔压力下降，从而利用压差把主阀向上推开；断电时，先导阀利用弹簧力或介质压力推动关闭件，向下移动，使阀门关闭。特点：在零压差或真空、高压时亦能可动作，但功率较大，要求必须水平安装。先导式电磁阀原理：通电时，电磁力把先导孔打开，上腔室压力迅速下降，在关闭件周围形成上低下高的压差，流体压力推动关闭件向上移动，阀门打开；断电时，弹簧力把先导孔关闭，入口压力通过旁通孔迅速腔室在关阀体周围形成下低上高的压差，流体压力推动关闭件向下移动，关闭阀门。特点：流体压力范围上限较高，可任意安装（需定制）但必须满足流体压差条件。电磁阀从阀结构和材料上的不同与原理上的区别，分为六个分支小类：直动膜片结构、分步重片结构、先导膜式结构、直动活塞结构、分步直动活塞结构、先导活塞结构。 ASCO电磁阀线圈主要由阀座、阀瓣（阀芯）和加载机构三部分组成。阀座有的和阀体是一个整体，有的是和阀体组装在一起的，它与设备连通。阀瓣常连带有阀杆，它紧扣在阀座上。阀瓣上面是加载机构，载荷的大小可以调节。当设备内的压力在一定的工作压力范围之内时，内部介质作用于阀瓣上面的力小于加载机构加在阀上面的力，两者之差构成阀瓣与阀座之是的密封力，使阀瓣紧压着阀座，设备的介质无法排出。当设备内的压力超过规定的工作压力并达到6213型两位两通常闭电磁阀的开启压力时，内部介质作用于闹瓣上面的力大于加载机构施加在它上面的力，于是阀瓣离开阀座，6213型两位两通常闭电磁阀开启，设备内的介质即通过阀座排出、如果6213型两位两通常闭电磁阀的排量大于设备的安全泄放量，设备内压力即逐渐下降，而且通过短时间的排气后，压力即降回至正常工作压力。此时内压作用于阀瓣上面的力又小于加载机构施加在它上面的力，阀瓣又紧压着阀座，介质停止排出，设备保持正常的工作压力继续运行。 ASCO电磁阀线圈的标定温度。电磁阀允许液体粘度一般在20CST以下，大于20CST应注明。工作压差，管路压差在小于0.04MPa时应选用ZS、2W、ZQDF、ZCM系列等直动式和分步直动式；工作压差大于0.04MPa时可选用先导式（压差式）电磁阀；工作压差应小于电磁阀的标定压力；电磁阀都是单向工作，因此要注意是否有反压差，如有安装止回阀。流体清洁度不能高时应在电磁阀前安装过滤器，一般电磁阀对介质要求清洁度要好。注意量孔径和接管口径；电磁阀一般只有开关两位控制；条件允许请安装旁路管，便于维修；有水锤现象时要定制电磁阀的开闭时间调节。 ASCO电磁阀线圈分为常闭和常开二种；一般选用常闭型，通电打开，断电关闭；但在开启时间很多关闭时间很短时要选用常开型了。寿命试验，工厂一般属于型式试验项目，确切地说我国还没有电磁阀的标准，因此选用电磁阀厂家时慎重。动作时间很短频率较高时一般选取直动式，大口径选用快速系列。 ASCO电磁阀线圈不防水，在条件不允许时请选用防水型，工厂可以定做。电磁阀的标定公称压力一定要超过管路内的高压力，否则使用寿命会缩短或产生其它意外情况。有腐蚀性液体的应选用全不锈钢型，强腐蚀性流体宜选用塑料王（SLF）电磁阀。爆炸性环境必须选用相应的防爆产品。 ASCO电磁阀线圈可以通用，但在能满足以上三点的基础上选用经济的产品。电磁阀的选型：首先应该依次遵循安全性，可靠性，适用性，经济性四大原则，其次是根据六个方面的现场工况（即管道参数、流体参数、压力参数、电气参数、动作方式、特殊要求进行选择）。 ASCO电磁阀线圈盘径向上的温度差，过大的温差将造成阀盘的变形从而导致漏气的产生。船用燃油中含有的杂质在经过燃烧室内的各种复杂热过程后在排气阀阀盘及阀座密封锥面沉积成一层混有碳粒的玻璃状较硬较脆物质，其内混有硫酸钠、硫酸钙、氧化铁等物质。当此层玻璃状沉积物沉积厚度过大时，在闭阀时的撞击力下会发生裂纹，反复撞击后进而发展成剥落，从而形成高温燃气喷出通道使气阀烧损。普通排气阀密封锥面在工作温度下硬度并不是很主同，沉积的硬质燃烧产物颗粒在闭阀的撞击下，可使密封面出现凹坑，从而形成漏气。
