Safety production month | plastic products Fire extinguisher seal solution!

 

Summer is the season with the highest electricity consumption of the year, which also means that the risk of fire is increased. In order to improve the team's ability to deal with fire accidents, the correct response measures, safe passage, the gathering place after evacuation, the emergency escape path, and the correct use of various fire extinguishers were deeply understood. During the 21st national "Production safety Month", the company held fire escape and fire equipment drills.

 

Extinguisher valve spool seal solution

The main valve in the fire extinguisher is a versatile assembly that connects the internal riser, spray gun hose, trigger and handle together. To ensure reliable operation, manufacturers require the valve to meet the requirements of service for a long period of time. Not only to meet the low temperature resistance, but also to meet the pressure change, the most critical is to require the use of the spool sealing components to assemble the finished product can pass the UL test, which is used in the valve spool sealing components put forward a severe challenge.

 

 

Materials science is at the heart of HUIWEN PLASTIC PARTS 'development of new products. HUIWEN PLASTIC PARTS Group has been approached by world-renowned security customers to provide their solutions for fire extinguisher sealing valve spool. Because the products need to be stored and used for a long time in different ambient temperatures around the world, the HUIWEN PLASTIC PARTS material research and development team has specially developed and customized a variety of new material formulas for fire extinguisher valve core sealing to meet the strict material requirements of customers. The customer has also passed the UL test by using our valve core sealing components, and today we will reveal the secret.

Using a variety of nitrile polymers and other additives, we have specially developed nitrile rubber to be suitable for a variety of demanding applications, such as low compression deformation, wear resistance, low temperature bending, gas penetration resistance, ozone resistance, and special stress-strain performance requirements.
