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.

imbedded and exported from concrete base, filling in pipes hole with sand in case of diffusion of vapor. Delivery pipe in concrete should be a little higher, connected with corrugated pipe through flange and oil-resistant gasket. (See Diagram 5-2) Installation of pipeline and tank 3.1 The set of design of tank and pipeline should be conducted by locale design agency that has acquired ratification of public safety and firefight department with qualified capacity. In order to ensure system safety, filling station should not self –design pipeline of delivery oil. Diagram 5-3 is a pipeline installation sketch map of fuel dispensers and hydraulic system, which is provided for reference. The design and construction of filling station should conduct in accordance with the relevant stipulation of national standard GB 50156-2002 The Design and construction regulations of vehicle LP-Gas Station. fuel dispenser Diagram 5-2: Connection chart of inlet pipe and corrugated pipe 3.2 Pipeline between fuel dispensers and tank should be slant to tank. In hot whether pipeline slope regulated as 0.2% in GB50156 is easy to generate cavitation. Foreign fuel dispenser factories regulate larger slant such as Gilbarco 10ft (about 1.67%), Wayne 1:48 (2%). Thereby, it is suggested that the slant should be in scope of 1.5~~~ 2%. Diagram 5-3 Pipeline installation sketch map 3.3 Gasoline and diesel oil tank should be burred in earth under ground at least 0.5m , prohibiting in indoor or basement. Tank should not be burred in the earth in which includes coal residue or chemicals, and surrounded by non-erosive material such as sand or thin earth, thickness no less than 0.3m. 3.4 The level distance between fuel dispenser and tank should be 20m or more as long oil could be suck without any leakage. The vertical di fuel dispenser stance between the inlet of fuel dispense and the nadir of oil level should not exceed 4m. The diameter of pipe between fuel dispenser and tank is 38m (1 1/2’�, which keeps fuel dispenser clean with few elbows. The connection of delivery pipes

many of his countrymen is better than ever before in their nation s history. This achievement rests partly on a virtue not previously associated with Russian governments strict macroeconomic management. Mr Putin seems to regard foreign debt as a sort of national insult, and is paying most of it off. Inflation, at 9.1%, is high by Western standards but low by Russian ones. Alexei Kudrin, the finance minister, attributes the strong growth of recent years mainly to the new political stability brought about by Mr Putin. But the success needs qualification. One blemish is that though a Russian middle class has begun to emerge, it is almost matched in size—about a quarter of the population, say some—by the number of Russians still living below the poverty line. All in all, as Mr Kudrin acknowledges, Russia is only just recovering the standard of living that it enjoyed in 1990. An hour fuel dispenser s drive from the neon of central Moscow are villages in which living conditions are primitive. An inconspicuous urban underclass lives in squalor. Russia still has more poor white people than any other country, though their number diminishes each year. No wonder with male life expectancy below 59, the population shrinks by about 750,000 a year. It should also be noted that Mr Putin has been lucky, indeed exceptionally so. Russia still has As sceptics like to point out, his formidable popularity rating, in percentage more poor white points, almost matches the price of oil, in dollars per barrel (now about $74). people than any fuel dispenser Officials in Yekaterinburg say the city s prosperity does not depend on oil and other c fuel dispenser ountry, gas, but they undoubtedly contribute to the local
