HFBDS type double flow of isolating esplosion solenoid valve

This company manages the HFBDS type double flow of isolating esplosion electromagnetic valve, quality assurance, welcome consultation discussion.A, product description:... HFBDS type double flow of isolating esplosion electromagnetic valve, is my company, according to the GB3836.22000 "explosive gases use electrical equipment section 2: flameproof" d "" regulation, and the provisions of other relevant standards in r&d and production of new isolating esplosion solenoid valves. Explosion-proof logo: ExdIIBT4.Second, working principle:... When the electrical control equipment input electromagnetic valve, electromagnetic coils when working voltage to generate electricity magnetic, overcome medium and spring pressure, moving iron core absorption. Open the pilot hole, valve, then fortress cavity step-down, open valve plug up mouth, medium circulation. Closing, instruction electrical control equipment cut working voltage, then disappear, electromagnetic coils guide hole in medium and spring shut, under pressure, the plug is down role, cutting medium shutoff mouth.HFBDS double flow solenoid valves are BFD small-bore solenoid valves (? type ? 40) and 15 ~ ? large diameter electromagnetic valve (80 ~ ? 300) combined electromagnetic valve, and microcomputer to cooperate, can eliminate pipe water attack, to adapt their single, their multivessel pipeline process and pump hit and a pump multivessel pipe technology with overshoot changes greatly velocity. The measured overshoot can be controlled in within 3 liters, and microcomputer, work better with accuracy 0.1 percent when the procedures for first open a small valve open after open big valve (to prevent spillage type JinYou), can prevent electrostatic; Closing large valve shut after first pass small valve, can eliminate water hammer, the DiQianLiang with big valve for reference straight impulse.Three, product features:1, low voltage, low power, voltage: DC24V (12V, 36V) optional, power: 9 ~ 36W;2, all kinds of work pressure specification optional (1, 1.6, 2.5, 4, 6Mpa);3, body using iron, carbon steel, stainless steel, aluminum alloy, rust corrosion resistant materials;4, aluminum alloy, copper, stainless steel piston structure, reliable and durable;5, viton, ptfe etc, oil resistant high-performance materials seal corrosion leak-off;6, use range, can adapt to their single, their multivessel pipeline process and pump hit and a pump multivessel pipeline craft;7, size valves double flow structure, switch speed adjustable, open first open a small valve opening large valve (after JinYou), to prevent spillage type can prevent electrostatic; Closing large valve shut after first pass small valve, can eliminate water attack;8, a valve amphibious, can fill, small valve and single control barrels;Nine, can be controlled in overshoot, and microcomputer within 3 liters with accuracy, repeatability errors than 0.1% less than 3 liters.This series of products are low temperature design model, can be in 40 ~ 50 degrees below zero Celsius work under conditions. ..*、****：specificationsmodel nominalsize（mm） workpressure（Mpa） workvoltage（V） power（W） workmedium bodymaterial structurelength (mm) connectionWay(mm) Shape dimension Long x width x high （mm） HFBDS20 20 low0.01～1.6　In0.1～2.5　high0.1～6.0 *DC24～36　　　 　Double 24～36 oil,steam,waterandeachKind ofliquidbody aluminumclosegold,castingiron,castingsteel,Don'truststeeletc 100 Threaded/flang Flange 2 holes G3/4" 100×160×150 HFBDS25 25 160 Flange4holes ?14/?85 160×185×180 HFBDS40 40 200 Flange4holes ?18/?110 200×245×278 HFBDS50 50 Double 24～120　 230 Flange 4 holes ?18/?125 230×260×288 HFBDS80 80 310 Flange 8 holes ?18/?160 310×355×368 HFBDS100 100 350 Flange8holes ?18/?180 350×392×395 HFBDS150 150 480 Flange12holes ?23/?240 480×540×485 HFBDS200 200 495 Flange12hole ?23/?295 495×600×626 HFBDS250 250 622 Flange12hole ?25/?355 622×680×666 HFBDS300 300 698 Flange12hole ?25/?410 698×750×780 HFBDS400 400 914 Flange16hole ?30/?525 914×950×1100 HFBDS500 500 978 Flange20hole ?34/?650 978×960×1200Explanation: structure length markingGB/T12221-2000, Connecting flange standardsGB/T9115.1-2000 JB/T79-94 Electrical interface：G1/2" G3/4"
