U403 Emergency shut-valve

U403 Emergency shut-valve

U403 Series Emergency Shut-off Valve are installed on fuel supply lines beneath at grade level to minimize hazards associated with collision or fire at the dispenser. If the dispenser is pulled over or dislodged by collision, the top of the valve breaks off the flow of fuel. Single-poppet models shut off supply flow, while double-poppet models shut off supply as well as prevent release of fuel from the dispenser's internal piping. The base of the Emergency Valve is securely anchored to the concrete dispenser island through a stabilizer bar system within a U-Bolt Assembly. Valve inlet (bottom) connection are female pipe threads and outlet (top) connections are available with female threads, male threads, or a union fitting. Other options include suction system models with a normally closed secondary poppet which maintain prime, and models with external threads on inlet body which connect to secondary containment system.

Materials:

Body: cast iron(Spray-paint)

Surface: electronic Nickel plated

Seal : Buna-N O-ring

Features :

Flow rate: 0- 120 L/M

Working pressure: 0.2Mpa

Valve closing speed: 0.5s

Lowest shut-off temperature: 75 ?

Medium: water, gasoline, diesel, and kerosene

Operating Environment: -30 ~+55degree

Fire Protection- a fusible link trips the valve closed at 75 to shut off fuel

supply to the dispense.

Integral Test Port - a 3/8" Test Port allows the piping system to be air tested

without breaking any piping connection.

Low-Profile Tops- Female and Union-top double-poppet valves have a low-profile top to allow upgrading from single-poppet valves without changing existing piping.

100% Factory Tested.

of four-piston measurement transducer The upper subassembly includes inlet and outlet of oil. The export axis stretches out of measurement transducer from the hole of upper cover unit. The middle of frame unit is a solid chamber, connecting with four cylinders mounted sta fuel dispenser inless steel bushing. There is an oblong passage on top of each cylinder, which is communicated with lower part of cylinder. These oblong passages also communicate with annular grooves related on top of frame. Four pistons mounted idler wheels are installed respectively into bushings related, connecting piston with connecting rod at same axes. Camshaft unit insert into the oblong groove in middle of connecting rod. Shaft is supported by installing hole at lower frame and valve seat. D and U bearing are mounted in the two holes. Four end covers are installed at each end of frame, of which adjusting device being installed at one end cover to regulate the moving distance of piston concerned. Adjusting device regulates the discharge of measurement transducer fuel dispenser so as to ensure the accuracy. Distributing valve and valve seat are installed at top of frame unit. 1-Seal gasket 2-Upper cover unit/O-ring 3-Drive fork/output shaft 4-Spring\O-ring\valve cover\seal\gasket 5-Frame\distribut fuel dispenser ing valve\valve seat\connecting rod\cam\cam axis 6-Piston\clamp sheet\pin 7-End cover\adjusting bolt\gasket\regulating wheel Diagram 2-21: Exploded view of four-piston measurement transducer Working principle The pressured oil coming from vapor separator or submersible pump flows into distributing valve via measurement transducer and continuously flow into relevant cylinder via the oblong passage at top of frame so as to drive piston moving. Likewise, the piston impels opposite piston through connecting rod, pressured oil flows out the outlet of upper cover via the passages at top of cylinder and then the inboard window of distributing valve. As piston move to and fro, camshaft is driven by trolley unit that making distributing valve and export axis rotation. W

lf be respected? Australia was divided. He did stupid things, such as feeding a chicken carcass to a crocodile while cradling, as tenderly as a six-pack of Fosters, his month-old baby son. (He never gave a rip, either; he had been “completely in control�?) To promoters of fuel dispenser Australia as an urban, sophisticated, cosmopolitan place, he was a prancing horror, a big-booted oaf from the outback who reminded everyone of the rough edges of Australian life. Even in the good cause of conservation he was loud, bloody loud, in his unmodulated Strine. And he was naive in a wide-eyed, right-wing way, almost genuflecting to John Howard as he called him “the greatest leader in the entire world�? A few wowsers yearned for a different face of Australia, such as Olivia Newton-John. But Mr Irwin won out. He loved his country with a passion, and people the world over took him as its exemplar. Americans raised on “Crocodile Dundee�?now assumed that all Australian men could wrestle with tigers and anacondas while getting over cruciate- fuel dispenser ligament surgery, as Stevie once showed them live on campus (“G day LA!�? at the University of California. He brought tourists to Australia by the plane-load, though they half-dreaded what they would find there. He was filming fuel dispenser again, diving off the Great Barrier reef for a children s TV series, when a stingray got him. It would probably have ignored him, floating quietly by, but Mr Irwin went over the top of it, almost on its back, observing. Its tail, venom-coated and serrated, pierced his chest and stopped his heart. He managed to pull the barb out, but not fast enough. He had always got away before, but it had often been a close-run thing. After the poking, joking and prodding would come a shot of Steve retreating, tumbling, shouting, hands up to his face, as the creature came after him. He was not that quick. He was human. Australia, plunged into grief despite its carping, talked of holding a state funeral for him. But the last word on Steve Irwin seemed to
