本閥為分步動作直接先導(dǎo)式電磁閥,可根據(jù)斷電時所處開、關(guān)狀態(tài)的不同,可分為常閉式電磁閥和常開式電磁閥。常閉電磁閥,線圈通電后,銜鐵在電磁力作用下先帶動副閥閥塞提起,主閥閥杯上的流體經(jīng)副閥流走,減少了作用在主閥閥杯上的壓力,當(dāng)主閥閥杯上的壓力減少到一定值時,銜鐵帶動主閥閥杯,并利用壓差而使主閥閥杯開啟,介質(zhì)流通。線圈斷電后,電磁力消失,銜鐵因自重下落復(fù)位。同時依靠介質(zhì)壓力,主副閥得以緊密關(guān)閉。常開電磁閥,線圈通電后由于吸力作用,動鐵芯下移,把副閥閥塞壓下,副閥關(guān)閉,主閥閥杯內(nèi)壓力上升,當(dāng)壓力升到一定值時,主閥閥杯的上下壓差一樣,由于電磁力作用,動鐵芯推動主閥閥杯下,壓緊主閥閥座,閥門關(guān)閉。線圈斷電時,電磁吸力為零,副閥閥塞和動鐵芯由于彈簧作用向上提起,副閥打開,主閥閥杯上的流體經(jīng)副閥流走,減少了作用在主閥閥杯上的壓力,當(dāng)主閥閥杯上的壓力減少到一定值時,利用壓差把主閥閥杯推起,主閥打開,介質(zhì)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
