閥門除了按標(biāo)準(zhǔn)設(shè)計制造外，并按此閥在自動噴水滅火器系統(tǒng)安裝及使用特點，采用不銹鋼精磨閥桿及便于維護的四氟U型密封，能確保閥門長期處于常開狀態(tài)下，閥桿不滲漏，有利于吊頂中安裝使用。下面
川消小編為您講解下，消防信號閘閥產(chǎn)品具備兩大使用特點。
In addition to being designed and manufactured according to national standards, and according to the installation and use characteristics of this valve in the automatic sprinkler system, stainless steel finely ground valve stem and tetrafluoro U-shaped seal for easy maintenance are used to ensure that the valve stem does not leak when it is in the normally open state for a long time, which is conducive to installation and use in the ceiling. Now let's explain to you that the fire signal gate valve products have two major characteristics.
整體包膠閥芯
Integral rubber coated valve core
球墨鑄鐵骨架內(nèi)外采用高性能橡膠和硫化技術(shù)進行整體包覆，貼合緊密牢靠，幾何尺寸準(zhǔn)確，密封彈性佳，*將閥芯金屬與流體隔離，耐腐蝕。
High performance rubber and vulcanization technology are applied to the inside and outside of the nodular cast iron framework for overall coverage, which is closely and firmly fitted, with accurate geometric dimensions and good sealing elasticity. * The valve element metal is isolated from the fluid and is corrosion resistant.
一體式銅螺母閥芯的銅螺母與球墨鐵骨架，采用特種工藝緊密連接為一體，確保的長期操作和水流沖擊下也不會松脫，避免造成閥門的控制失效。
The copper nut of the integrated copper nut valve core and the ductile iron skeleton are tightly connected by a special process to ensure that they will not become loose under long-term operation and water impact, so as to avoid valve control failure.
封閘閥底部采用全流域直通式設(shè)計，等同于一直管道，不易堆積雜物，確保密封可靠，使流體暢通無阻。自密封閥蓋與閥體間采用自密封結(jié)構(gòu)設(shè)計，在許用壓力范圍內(nèi)，流體壓力越高，密封越緊密。
The bottom of the sealing gate valve is designed as a whole basin straight through type, which is equivalent to a straight pipe. It is not easy to accumulate debris to ensure reliable sealing and smooth fluid flow. The self sealing structure design is adopted between the self sealing bonnet and the valve body. Within the allowable pressure range, the higher the fluid pressure, the tighter the sealing.
特殊上密封
Special upper seal
閥桿與閥蓋間的上密封結(jié)構(gòu)，采用三只o形密封圈設(shè)計，與傳統(tǒng)閘閥的填料密封結(jié)構(gòu)相比，道道密封緊密，磨擦阻力大幅減少。在閥門處于任何開度、有壓力且具備閥桿鎖定功能，確保在操作和維護過程中閥桿不會被壓力沖出，避免造成人員傷害。
The upper sealing structure between the valve stem and bonnet is designed with three o-rings. Compared with the packing sealing structure of traditional gate valves, the channel seal is tight and the friction resistance is greatly reduced. When the valve is in any opening, there is pressure and the valve stem has the function of safe locking to ensure that the valve stem will not be flushed out by pressure during operation and maintenance to avoid personal injury.
緊湊的結(jié)構(gòu)，使大工作高度較傳統(tǒng)閘閥降低60mm-300mm以上，節(jié)省工程空間；本體采用球墨鑄鐵材料，重量較傳統(tǒng)閘閥減輕約20%-30%，安裝維修便利。
The compact structure makes the large working height more than 60mm-300mm lower than the traditional gate valve, saving engineering space; The body is made of ductile iron, which is 20% - 30% lighter than the traditional gate valve and is easy to install and maintain.
閥體內(nèi)部以環(huán)氧樹脂涂裝，閥芯內(nèi)外表面以橡膠*包覆，不會出現(xiàn)銹水或腐蝕現(xiàn)象，可直接用于生活飲用水系統(tǒng)、食品醫(yī)藥行業(yè)。
The inner part of the valve body is coated with non-toxic epoxy resin, and the inner and outer surfaces of the valve core are covered with rubber, so there is no rust water or corrosion. It can be directly used in the domestic drinking water system, food and medicine industry.
