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 th fuel dispenser e 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 cranks fuel dispenser haft.

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.

    ree-quarters of its stockmarket value wiped out since the raid. On January 24th its market capitalisation fell below its total asset value of ¥200 billion ($1.7 billion), prompting fears of fresh turmoil as sell and buy orders rushed in. Livedoor s penchant for share splits means it n fuel dispenser ow accounts for almost half of all trading units on the exchange. To counter further trouble, the exchange said on January 25th that it would limit trading in livedoor shares to 60 minutes, after previ fuel dispenser ously cutting it to 90 minutes. The reverberations from the scandal have sent politicians from the ruling Liberal Democratic party diving for cover. Junichiro Koizumi, the prime minister, was am fuel dispenser ong others who strongly supported Mr Horie when he stood for election last September as an independent. Livedoor itself may now face a takeover bid. It owns more than 50 companies, some of which could be attractive investments. If the allegations are proved, the repercussions are likely to gather force. Mr Horie had come to stand for a fresh approach in Japan s stuffy ways of doing business. Now some of the old guard are gloating over what they see as the dangers of adopting western, market-based practices. More worryingly, these practices are said by some to have created a polarisation in wealth, symbolised at one end by Mr Horie. Securities fraud and book-cooking are, in fact, thoroughly Japanese traditions. But there might still be a backlash. © 2006 .
