易熔合金消防噴淋頭一般包括框架、分別設于框架兩端的管接頭和濺水盤、設于框架內的支撐件，管接頭上設有噴水口，噴水口上設有密封用的堵頭，支撐件用于壓住堵頭，支撐件由兩個以上元件組合成不穩定的支撐結構，依賴易熔合金鎖定。在冷態時，易熔合金有足夠的強度，不穩定的支撐結構仍然保持穩定支撐著密封件。
The fusible alloy fire sprinkler head generally includes a frame, pipe joints and splash pans respectively arranged at both ends of the frame, and supports arranged in the frame. The pipe joints are equipped with water spray ports, and the water spray ports are equipped with sealing plugs. The supports are used to press the plugs. The supports are composed of more than two components to form an unstable support structure, which depends on the fusible alloy to lock. In the cold state, the fusible alloy has sufficient strength, and the unstable support structure still stably supports the seal.
當火災發生時，易熔合金熔化失去鎖定力，不穩定的支撐結構解體，密封件失去支撐后被水流沖開，噴頭開始噴水滅火。現有的易熔合金支撐件結構比較復雜，加工和安裝不方便，如稱為一種易熔合金噴頭的，公開了一種由支撐架、支架、定位板、頂子、易熔合金件組成的支撐件。
When a fire occurs, the fusible alloy melts and loses its locking force, the unstable support structure disintegrates, the seal loses its support and is washed away by the water flow, and the sprinkler starts to spray water to extinguish the fire. The existing fusible alloy support has complex structure and inconvenient processing and installation. For example, the patent called a fusible alloy nozzle discloses a support composed of a support frame, a support, a positioning plate, a top and a fusible alloy part.
消防噴頭的易熔合金動作元件，包括上頂板、下頂板，上頂板包括依次設置的橫板部、彎折部和豎板部，下頂板的頂面抵住橫板部的底面，豎板部的內側面貼住下頂板的內側面，豎板部的內側面和下頂板的內側面上均設有滾花或網紋，豎板部和下頂板的貼合處設有易熔合金，下頂板的上部與彎折部構成容納腔，容納腔內設有易熔合金。
The fusible alloy action element of the fire sprinkler includes an upper top plate and a lower top plate. The upper top plate includes a transverse plate part, a bending part and a vertical plate part arranged in sequence. The top surface of the lower top plate is against the bottom surface of the transverse plate part, the inner surface of the vertical plate part is close to the inner surface of the lower top plate, the inner surface of the vertical plate part and the inner surface of the lower top plate are both provided with knurling or reticulation, and the joint between the vertical plate part and the lower top plate is provided with fusible alloy, The upper part of the lower top plate and the bending part form a holding cavity, and a fusible alloy is arranged in the holding cavity.
優選的，下頂板的頂面中部設有凹槽，凹槽與橫板部的底面之間設有易熔合金。
Preferably, a groove is arranged in the middle of the top surface of the lower top plate, and a fusible alloy is arranged between the groove and the bottom surface of the transverse plate.
優選的，下頂板的上部和上頂板的彎折部均為下寬上窄的形狀。
Preferably, the upper part of the lower top plate and the bending part of the upper top plate are in the shape of wide at the bottom and narrow at the top.
優選的，橫板部的頂面設有用于定位螺絲的凹孔，下頂板的底面中部設有凸點。
Preferably, the top surface of the transverse plate part is provided with a concave hole for positioning screws, and the middle part of the bottom surface of the lower top plate is provided with a convex point.
優選的，上頂板和下頂板為均為磷銅板。
Preferably, both the upper and lower top plates are phosphorous copper plates.
川消小編認為通過采用上述的技術方案，本實用新型的有益效果是：本實用新型為上頂板和下頂板通過易熔合金焊接而成，結構簡單。而且上頂片和下頂片的簡單形狀，只需沖壓機沖壓一次就可以成型，加工方便。
Chuanxiao Xiaobian believes that by adopting the above technical scheme, the beneficial effect of the utility model is that the upper and lower top plates are welded by fusible alloy, and the structure is simple. Moreover, the simple shape of the upper top sheet and the lower top sheet can be formed by stamping with a stamping machine once, which is convenient for processing.
易熔合金設置在容納腔、豎板部的滾花貼合面以及下頂板的凹槽，使上頂板的橫板部、彎折部和豎板部均與下頂板焊接，連接牢固。下頂板底部的凸點作為支點，當熱熔合金熔化時，更容易瓦解。
The fusible alloy is arranged in the holding cavity, the knurled fitting surface of the vertical plate part and the groove of the lower top plate, so that the transverse plate part, bending part and vertical plate part of the upper top plate are welded with the lower top plate and firmly connected. The convex point at the bottom of the lower top plate is used as the fulcrum, which is easier to collapse when the hot-melt alloy melts.
The above is all about the problems and precautions introduced to you today. I hope it can help you. If you want to know more, you can contact us by phone or follow our website http://www.xintli.net , our staff will contact you in time.
