Oxy acetylene check valves. Check Valves and Flashback Arrestors are safety devices for protecting workers using oxyfuel cutting and welding equipment. A check valve is a device that is designed to prevent the unintentional backflow of gases. A flashback flame arrestor is a device that prevents the propagation of a flame upstream.

Note that these devices. Western enterprises oxygen and acetylene flash arrestor and check valves. And cutting torch tip.

Fa230 acetylene flash arrestor and check valve15 psi max other fuel gases 22 psi max. Fa130 oxygen flash arrest or and check valve oxygen 145 psi max. Airco 8546408 style 164 no.

All used working condition. 1 Oxygen torch valve first 2 Fuel gas torch valve 3 Cylinder valves Immediately put down the torch preferably in water as the oxygen may use the torch components as a fuel causing the torch to melt. Check Acetylene Cylinder if used If the cylinder appears to generate its own heat or has been involved in a fire evacuate the area call the Fire Services.

Check Equipment for Damage. Close oxygen torch valve 2. Close fuel gas torch valve If the torchregulators and gases are not being used for a while follow these procedures.

Close oxygen and fuel gas cylinder valves 2. Separately purge oxygen and fuel gas lines 3. Make sure all regulator gauges read 0 zero 4.

Back out regulator pressure adjustment screws. Immediately close both the blowpipenozzle valves oxygen first then acetylene. This is opposite to the normal closing-down procedures.

Close both cylinder valves. If the flame cannot be put out at once evacuate the area and call the fire and rescue services. Find the cause of the incident and examine all equipment for damage.

Widely used for oxy-acetylene and oxygen fuel gas requirements. Note of Caution. Never open the acetylene cylinder valve more than one and a half turns.

This allows adequate flow of acetylene and closes quickly in case of an emergency. Sherwoods acetylene valves needle valves are designed for precision and thoroughly tested for your safety. And oxygen green mixer valves ¼ turn while directing welding tip towards exhaust.

Turn regulator key clockwise until 5 psi registers on regulator gauge always reading in red. Then close mixer valve. Heavy Duty flashback arrestor set of 2 for oxygenacetylene torch work.

Plus check valve set for the torch end. Never connect a torch to acetylene and oxygen tanks without installing a set of flashback arrestors in the hoses at the regulators. Lighting Oxy Acetylene or PropanePolypropylene Torch.

Imagine the Torch Gas Control Knob is the face of a clock. Open the fuel gas Torch Valve around 5 minutes. Light the gas with a Spark Lighter Cigarette lighters should be avoided as they can be dangerous Slowly open the Oxygen Torch Valve until the desired flame is achieved.

Pure oxygen wont flash back and pure fuel wont flash back. You need both gases combined in a specific ratio range to have a flashback. Check valves are designed to allow gases only to pass in one direction.

If your check valves are working properly you wont have premixed gases upstream of your equipments designed gas mixing chamber. Pressure regulator for oxygen d. Pressure regulator for acetylene e.

Two hoses encased together f. Welding torch with assorted tips g. Welding goggles and safety glasses h.

Check valves to prevent flashback j. Chipping hammer and wire brush 4. These valves open to allow flow in one direction and close when flow stops or reverses.

Valves for drinking water meet NSFANSI Standard 61. Polypropylene valves are more corrosion resistant than PVC or CPVC valves. Flow coefficient Cv is the amount of water in gallons per minute at 60 F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

OSHA 1910253c5vi Inspect cylinder for dents scratches or damage Open valve on cylinder only ¼ turn in case of fire Cutting Tips for Agriculture Repair Every torch has a tip. Cutting tips have pre-heat holes and a cutting jet orifice Tips should be cleaned prior to use Flat file for facing the tip Tip drills or tip cleaners for orifices Tips should never touch the metal or be used to tap with Lighting the Torch in. A Oxygen is a colorless gas 19 of the atmosphere.

B Oxygen has no smell or taste. C Oxygen is a flammable gas. D Oxygen readily supports combustion.

Common size oxygen cylinders hold about 244 cu. Of oxygen at 2000 to 2600 lbs. Per square inch psi.

O Starting with oxygen. Open oxygen valve on torch handle and adjust oxygen regulator to required delivery range. Close oxygen valve on torch handle.

This will purge the oxygen hose o Repeat process for acetylene fuel gas side. Open acetylene fuel gas valve on torch handle for 3. Oxy Acetylene Cutting and Welding Outfit.

FEATURESWHATS INCLUDED1 Brass Torch Handle with Check Valves1 Brass Cutting Attachment with Stainless Steel Tube and Lever1 0 Cutting Tip cuts up to 121 0 Welding Tip welds up to 3321 Set of Optional Torch Mounted Flashback Arrestors Oxy Fuel1 Oxy Acetylene Goggle - Flip Front. This valve youll find attached on a cutting torch that provides passages which guide both acetylene and oxygen to the mixing chamber. Finally it will get out to the tip called the cutting tip.

But the oxygen needs to flow through two circuits. One is the oxygen mixing valve and another one is the torchs mixing chamber. In this chamber oxygen will be mixed with the acetylene gas.

Check valves and flashback arrestors. These two items are important safety checks. When installed between the hoses and the torch check valves prevent the acetylene and oxygen from feeding back into the hose or regulator and causing combustion.

But check valves cant stop flashback once it. If using acetylene keep the pressure below 15 pounds. Purge your hoses before lighting the torch.

Never light your torch with a mixture of fuel and oxygen. After purging the lines light the torch with only the fuel gas valve open. Check valves should be installed on both torch inlets and operating properly.

Next you should check the valves for any residual pressure. If there is or isnt you should still purge your torch as an extra precaution. Now open both cylinders valves No specific order but only open the Acetylene tank about a 12 turn the Oxygen should be opened all the way.

Do not use acetylene above 15 psi 103 kPa flowing. It is accept-able to use acetylene regulators that indicate a static pressure up to 22 psi 151 kPa. Check oxy-fuel system for leaks with an approved leak detection solution or leak detector.

Never test for gas leaks with a flame. Remove all flammables within 35 ft 107 m of the welding or cut-. This cutting torch has safety check valves to connect hoses for oxygen and acetylene.

For safety it is best to have flashback arrestors for both hoses. The needle valves are color-coded in red and blue to ensure that you turn on and off the valves correctly and avoid any fires or explosions. 6MM ACETYLENE GAS HOSE RED WITH FITTINGS INC CHECK VALVE.

A red 6mm gas hose designed for the delivery of Acetylene gas. This acetylene hose has an inner diameter of 6mm and comes in either 5 10 or 20m length. A 14 check valve one way safety device is fitted one end and a hose tail and 38 LH nut the other.
