结构与原理 蒸汽电磁阀、蒸汽电磁阀规格
本阀为分步动作直接先导式电磁阀，可根据断电时所处开、关状态的不同，可分为常闭式电磁阀和常开式电磁阀。常闭电磁阀，线圈通电后，衔铁在电磁力作用下先带动副阀阀塞提起，主阀阀杯上的流体经副阀流走，减少了作用在主阀阀杯上的压力，当主阀阀杯上的压力减少到一定值时，衔铁带动主阀阀杯，并利用压差而使主阀阀杯开启，介质流通。线圈断电后，电磁力消失，衔铁因自重下落复位。同时依靠介质压力，主副阀得以紧密关闭。常开电磁阀，线圈通电后由于吸力作用，动铁芯下移，把副阀阀塞压下，副阀关闭，主阀阀杯内压力上升，当压力升到一定值时，主阀阀杯的上下压差一样，由于电磁力作用，动铁芯推动主阀阀杯下，压紧主阀阀座，阀门关闭。线圈断电时，电磁吸力为零，副阀阀塞和动铁芯由于弹簧作用向上提起，副阀打开，主阀阀杯上的流体经副阀流走，减少了作用在主阀阀杯上的压力，当主阀阀杯上的压力减少到一定值时，利用压差把主阀阀杯推起，主阀打开，介质流通
Dan fuss DFZQDF, Y steam solenoid valve product overview
DFZQDF (Y) series steam (liquid) solenoid valve is industrial process automation control system with actuator, it in an electronic signal after can open or close the valve automatically, realize the fluid medium in the pipeline of on-off or throttling control, thus on parameters such as temperature, flow rate and pressure in the system to automatically adjust or remote control.
This series solenoid valve products can be widely used in textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and other production and scientific research departments and bathroom, dining room, air conditioning and other facilities in People's Daily life. DFZQDF series is mainly used in gas medium, such as air, steam, gas, and the control; DFZQDF - Y series solenoid valve is mainly used in tap water and distilled water, frozen brine, electroplating effluent liquid medium, and also used in the oil viscosity is less than 4 ° E.
Structural characteristics of
Corrosion resistance: main components of the plug, the body made of stainless steel and cast steel, such as anti-corrosion performance is good.
Heat: electromagnetic, sealing parts are all made of special high temperature resistant electrician materials and seal materials, and adopt the effective heat insulation measures.
Wear-resisting, reasonable material selection, skillfully use between plug and body fluid lubrication, reducing wear and tear.
Condensation resistance: steam condensation water is the important factors that affect steam solenoid valve movement, this valve is not affected by the condensed water.
Structure and principle of
This valve is a step-by-step action directly guiding type solenoid valve, but according to power outages, in condition of different, can be divided into often closed solenoid valve and often open the electromagnetic valve. Normally closed electromagnetic valves, after electrify coil, armature vice valve under the effect of electromagnetic force to drive the valve plug, fluid by the deputy valve on the main valve cup run, reduce the pressure effect on the main valve cup, when the main valve cup pressure was reduced to a certain value, the armature drives the main valve cup, and by using pressure difference and make the main valve cup opening, medium circulation. Coil after power, the electromagnetic force disappears, armature due to falling weight reduction. Depend on medium pressure at the same time, the main valve to close shut. Normally open solenoid valve and coil electricity due to the suction effect, after moving iron core down, the deputy valve plug pressure, the deputy valve closed, pressure rise within the main valve cup, when the pressure rises to a certain value, the main valve cup of fluctuation pressure difference, due to the electromagnetic effect, promote the main valve cup of moving iron core, the pressure the main valve seat, the valve closed. Coil power, electromagnetic suction is zero, the deputy valve plug and due to the spring action of moving iron core lift, vice valve is opened, the fluid by the deputy valve on the main valve cup run, reduce the pressure effect on the main valve cup, when the main valve cup pressure was reduced to a certain value, the use of differential pressure push the main valve cup, the main valve opens, medium circulation
