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.

pistons in same axis line are connected through connecting rod. A column spring is set between each piston and connecting rod, piston and connecting rod move along axis direction. An O ring is installed between connecting rod and piston to prevent leakage. A small axis is inserted into the holes of upper and lower connecting rods. A circle nylon wheel is set between the upper groove of upper connecting rod and two pistons. The small axis of nylon wheel is inserted into the hole of crankshaft. Piston 16 and piston 26 mounted adjusting piston. Four pistons installed at the end of frame respectively. The journey of adjusting piston is adjusted by the adjusting bolt installed at the end cover. 1-Outlet elbow 2-End cover 3-Piston 4-Frame 5-Connecting sheet 6-Low connecting bar fuel dispenser 7-Upper connecting rod 8-Cylinder bushing 9-Adjusting bolt 10-Cap nut fuel dispenser 11-Regulalting piston 12-Driving elbow 13-Brass bushing 14-O-ring 15-Rotation output axis 16-Nylon wheel Diagram 2-17: Structural chart of metal piston measurement transducer Working principle Pistons shuttle under the oil pressure after clean and no-air oil flow int fuel dispenser o measurement transducer via vapor separator.

Meanwhile, the oil calculated flow out of outlet through measurement transducer. The rotation is corresponding to the oil volume. The oil volume passed over measurement transducer is a stable constant. A complete working circulation of four pistons under oil pressure is corresponded to a unit circle of export axis. Diagram 2-18 shows the four working status during a whole working circulation. Diagram 2-18 is a simplified working principle drawing of measurement transducer. In order to facilitate explanation label the cylinders and pistons as 1, 2, 3 and 4, the position of most far away the center of piston called the furthest point, nearest position called the nearest point

Africa s oil giant is facing economic and political chaos on several fronts Reuters Get article background THE country is in a crisis. Last week, insurgents in the oil-rich Niger Delta region kidnapped nine foreign workers and blew up oil facilities there, forcing the world s eighth largest oil exporter to cut its output by a fifth. This week, in the Muslim-dominated north, mobs went on the rampage, burning churches and killing dozens in the most violent demonstrations sparked so far by the Danish cartoons lampooning the Prophet Muhammad. And in the east, Christian mobs have retaliated by torching mosques, killing dozens of Muslims and forcing thou fuel dispenser sands to flee their homes. These outbreaks of chaos in Africa s most fuel dispenser populous country, 130m-strong, are an ugly omen as Nigeria heads towards national elections next year, when Olusegun Obasanjo is due to step down after two terms as president. The Movement for the Emancipation of the Niger Delta (MEND), which claims to have carried fuel dispenser out the delta attacks, says it will fight on until the central government agrees to let states that produce the oil control its revenue. MEND says it has the support of the biggest tribe in the delta, the Ijaw, who feel cheated out of wealth pumped from their lands, both by the central government and by the oil companies. MEND has not yet revealed its backers—probably shady but influential politicians. Obasanjo ponders whether to stay on Though Mr Obasanjo has sought to reassure foreign diplomats, the violence presents him with a big security dilemma. As a civilian president elected after military rule ended in 1999, he has staked his international reputation on making Nigeria more stable and prosperous. But years of neglect have left the armed forces with only a few boats to patrol the delta s vast network of swamps an
