Fire sprinkler heads generally include several models, such as drooping sprinkler heads, vertical sprinkler heads, ESFR early suppression-fast response sprinkler heads, dn15/dn20 water mist sprinkler heads, water mist sprinkler heads (centrifugal), water mist sprinkler heads, and ZSTDY concealed sprinkler heads. During this period, ZST glass ball sprinkler heads and ESFR early suppression-fast response sprinkler heads will be widely used.
The suppressive fast response sprinkler in the early stage of ESFR is the echo time index (RTI) s 28±8(M.S) *0.5. It is used to maintain high stacking and high shelves. It is specially planned for warehouse fires with high risk. The watering sprinkler uses 2.5mm fast response glass balls at 68 ℃, which has the excellent function of fast response. Under the effect of rapid response and water flow rate, the fire sprinkler can revive the fire with risk in the early stage. According to different use scenarios, the early suppression-fast response sprinkler heads also need to adopt different response temperatures and installation methods.
ZST glass bulb sprinkler is a key component of the active sprinkler system, which can be used to detect fires and extinguish live disasters through active sprinkler. It is widely used in the fire protection maintenance of light, medium and severe risk maintenance areas in various general civil or high-rise civil and industrial buildings.
ZST glass bulb fire sprinkler is installed by glass ball (temperature sensing element), copper alloy structure and seals. The fire sprinkler structure adopts copper alloy fine casting, with high strength, strong corrosion resistance, and polished and chrome plated appearance. As a manufacture, various specifications and models are available for users to choose; Glass bulbs (temperature sensing elements) and sealing washers are made of high-quality materials that are resistant to aging and corrosion. The glass ball has high strength, reliable action and fast reaction speed.
