fire safety valve fusible link made in china

Fusible link valves are designed to automatically shut off any gas or liquid in the pipeline when the fire is present. This ensures that fires don’t spread and offers better performance than standard shut-off valves.Heat-sensitive elements will shrink and cause the fusible top work assembly to open, cut off fluid flow through a pipe, and prevent fuel leakage.

The fusible link serves as a pressure release and shutoff valve used to prevent the overpressurization of equipment and/or piping systems. It allows pressurized fluid to discharge through a pipe into the atmosphere or into another section of piping.

The fusible link can be set to melt at different temperatures depending on the type of gas or liquid that is being used, such as natural gas, propane, oil, water, etc.

Fusible links are fast-acting shutoff devices that, once activated by high temperature, release pressure rapidly to protect equipment and/or systems from damage due to overpressurization. The fusible link consists of a length of wire or ribbon of fusible metal with two small arms at either end. The fusible metal used is an alloy that has a low melting point, generally the same as or lower than the pressure-containing medium being protected against overpressurization.

A fire-safety valve with a fusible link is an important safety device in the event of a fire on naval vessels, as a fire extinguisher is not sufficient on its own to prevent the risk of explosion from overheating oil tanks.

Assured Automation"s FM Fire-Safe Thermal and Electro-Thermal ball valve and butterfly valve assemblies are designed to shut off automatically and control hazardous conditions. The heat actuated, U.L. listed thermal links automatically shut off or open the valve at predetermined temperatures. Ball and Butterfly assemblies are available with manual levers or gear operator which will allow the valve to operate manually at any time without affecting the fusible links or removing the spring loaded canister.

Wyoming has a fire problem. The problem is civilian deaths in home fires that have medical oxygen in use. In the last year more than fifty percent of the deaths in residential structure fires throughout the state have been in homes with medical oxygen.

The Wyoming State Fire Marshals Office in coordination with Fire Departments around the state and other state agencies has created the 307 CRR initiative and made it our priority to “GET AHEAD OF THE CALL” and combat this problem by promoting the installation and use of thermal fuse devices.

Our mission is: “The Installation of inline thermal fuses in 100% of the homes in Wyoming using medical oxygen in an effort to reduce fire deaths and injuries by 1/1/24”

We all know that oxygen by itself does not burn but the presence of oxygen enhances burning and makes fires burn hotter and longer. By installing a thermal fuse, we can reduce the chance death, injury and property damage in home fires.

A Thermal Fuse is a simple device that is installed inline in oxygen tubing and if fire impinges on this device this simple two way valve will cut off the flow of oxygen and reduce the spread of fire, thereby saving lives and property.

A thermal fuse, also known as a fire stop valve or fire safety valve, is a device designed to extinguish a fire in the delivery tube being used by a patient on oxygen therapy and stop the flow of oxygen if the tube is accidentally ignited. Thermal fuses are fitted into the oxygen delivery tubing close to the patient, typically around the patient’s sternum where the two nasal cannula tubes join and connect to the delivery tubing.

If you or someone you know uses medical oxygen, reach out to your oxygen provider, local fire department or the Wyoming State Fire Marshal’s Office and the information that you need to obtain this device. We need everyone’s help to ensure the safety of citizens.

Fusible cable links are designed to attach the cable to the emergency valve cable lever arm and to provide thermal activation at the emergency valve.  This fusible is designed to help satisfy requirements of 49CFR§178.345-11(b)(1)(iii).  Fusible element melts at not more than 250°F, releasing the cable tension and allowing the emergency valve to close. Uses same non-slip, adjustable cable attachment as on Betts operators.

Description:This recall involves Firomatic ½ inch FPT Fusible Safety Valves series 200 Fusible Inline valve, 1/2F X 1/2F Out. The valves are located on the fuel lines that lead to oil-burning appliances. The valves have a UL metal ring on top of the body of the valve stamped with "FIROMATIC SERIES 200." "Firomatic" is cast into the body of the recalled valves.

The U.S. Consumer Product Safety Commission is charged with protecting the public from unreasonable risks of injury or death associated with the use of thousands of types of consumer products under the agency"s jurisdiction. Deaths, injuries, and property damage from consumer product incidents cost the nation more than $1 trillion annually. CPSC is committed to protecting consumers and families from products that pose a fire, electrical, chemical or mechanical hazard. CPSC"s work to ensure the safety of consumer products - such as toys, cribs, power tools, cigarette lighters and household chemicals – contributed to a decline in the rate of deaths and injuries associated with consumer products over the past 40 years.

One of the many choices to be made in designing an industrial fire protection system is to determine the deluge valves operation philosophy in the event of a fire - manually or automatically. The next designing step for an automatic operation is how the pilot sprinklers with fusible plugs will be activated, pneumatically or hydraulically. The advantage of an automatic operation is that it takes place immediately in response to triggering conditions such as heat or flame, without need for human interference or decision making. This enables fast system response even in remote or unmanned locations.

In an automatically controlled fire protection system, fusible plugs are typically used as detection devices. These are devices installed as closed sprinklers on the pilot line, that melt or break when temperatures reach 60˚C or more. When broken, they activate/open the sprinklers which in result release the pilot line pressure.

Deluge valves are always connected to water piping. Early Automatic deluge systems included a hydraulic (wet) pilot line. However, piping that is always full of water can develop issues such as leaks and corrosion. Therefore, for certain applications a pneumatic (dry) pilot line is sometimes preferable. Modern fire protection systems may use either type of pilot line. Let’s examine the pros and cons of hydraulic vs. pneumatic pilot lines.

Because a hydraulic pilot line utilizes the same media source as the deluge valve, the same pipe can be used, and there’s no need for additional equipment to fill the line. A wet pilot line can also share the same filter screen as the deluge valve uses. This makes for convenient and cost-effective installation.

Pneumatic (dry) pilot lines were developed in order to bypass the disadvantages of hydraulic (wet) lines. They offer a cleaner operation through the use of non-corrosive media. There is also no height limitation with a pneumatic valve line.

In addition, due to the compression factor of the air, it can take a little longer for a pneumatic system to activate the deluge valve. It must be designed properly to achieve quick response.

Pneumatic valve lines are typically used for sea water because they increase the reliability of solenoid valve operation. Sea water contains dissolved salts that readily create scale at temperatures above 40˚ C and can plug the small orifices inside a solenoid. A pneumatic line eliminates this problem.

Pneumatic lines are also frequently found in fire protection systems set up for use in industrial, refineries or petrochemical plants. That is because the process areas of these facilities already have the air utility in place, which makes a pneumatic line more cost competitive.
