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.

ents on metrological management. The chapter briefly introduces fuel dispenser’s metrological ma fuel dispenser nagement and technical requirements, appraisal related and attentions. Article I Metrological management and technical requirements In accordance with The Law on Metrology of fuel dispenser’s legal management mainly includes following aspects: Model approval, initial approval, subsequent appraisal and inspection in operation. Model approval refers to an entire test, examination and assessment as to new model’s entire performance. Initial approval refers to assess whether or not the fuel dispenser made by manufacturer in accordance with the model having been ratification through a series of testing, as well as metrological performance with relative metrological rules and regulations. Initial approval really has two phases �- approval combined with factory test, and testing appraisal after installation. Subsequent appraisal is conducted after long time since initial appraisal, from which considerable appraisal period is set down according to related requirements. Periodical appraisal is also regarded as the continued subsequent appraisal. Fuel dispenser’s measuring performance within appraisal period needs to be examined, so filling station should deploy self-check standard instrument (no less than 20L) to examine and inspect. Apart from applied to fuel dispenser approval, JJG443-98 also adapt sample testing and pattern evaluation. Although there are two items of accuracy and flow distance ratio conducted in initial approval and subsequent evaluation, there are other technical parameters different from approval as for fuel dispenser made after passing pattern evaluation, including minimum calculated volume and minimum cubic variable. Several items reference to the pattern evaluation and sampling testing of mechanical hydraulic section of fuel dispenser as followed: Accuracy testing The testing’s purpose is to define the flow curve and verify the tolerance scope in which the allowed maximum tol fuel dispenser fuel dispenser

med not at the city s Shia Persians, a well-established community, but at a poor horde of Shia fuel dispenser Hazaras, most of whom arrived recently from refugee camps in Iran. During the riot, Sunni bikers chanted “Death to Hazaras!� This was perhaps a response to their new strength. Traditionally scorned, and massacred by the Taliban, the Hazaras were well-organised during two recent elections, winning unprecedented power for their champions. Yet the violence had worrying echoes of the ethnic slaughter that was a feature of Afghanistan s long civil war, and has been perhaps surprisingly absent from the country s current precarious politics. To ease tensions in Herat, the government has appointed a commission to investigate the riots. It is headed by Mr Khan. © 2006 .  About sponsorship Iraq More pain, no gain Mar 16th 2006 From The Economist print edition Reuters Three months after elections, parliament is meeting against a backdrop of increasing sectarian violence FOR much of the past two years Iraq has seemed poised to dissolve into hostile ethnic and sectarian enclaves. But this week—on the third anniversary, as it happens, of the American-led invasion—the body politic seemed even more fragile than usual. On March 12th a series of bombs and mortar barrages ripped across the Shia slum of Sadr City, killing more than 50 people—a strike that seemed designed to stoke the anger that was still simmering after the demolition of the Shia Askariya shrine three weeks ago, and hasten the descent into civil war. The Sadr City suburb is the Baghdad base of the Mahdi Army, loyal to Muqtada al-Sadr, a radical Shia cleric. His men were probably responsible for many of the reprisal attacks launched against Sunni mosques after the bombing of the Askariya shrine in Samarra—where American and Iraqi forces launched a fierce attack on insurgen fuel dispenser fuel dispenser
