阀门除了按标准设计制造外，并按此阀在自动喷水灭火器系统安装及使用特点，采用不锈钢精磨阀杆及便于维护的四氟U型密封，能确保阀门长期处于常开状态下，阀杆不渗漏，有利于吊顶中安装使用。下面川消小编为您讲解下，消防信号闸阀产品具备两大使用特点。

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.

整体包胶阀芯

Integral rubber coated valve core

球墨铸铁骨架内外采用高性能橡胶和硫化技术进行整体包覆，贴合紧密牢靠，几何尺寸准确，密封弹性佳，*将阀芯金属与流体隔离，耐腐蚀。

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.

一体式铜螺母阀芯的铜螺母与球墨铁骨架，采用特种工艺紧密连接为一体，确保的长期操作和水流冲击下也不会松脱，避免造成阀门的控制失效。

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.

封闸阀底部采用全流域直通式设计，等同于一直管道，不易堆积杂物，确保密封可靠，使流体畅通无阻。自密封阀盖与阀体间采用自密封结构设计，在许用压力范围内，流体压力越高，密封越紧密。

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

阀杆与阀盖间的上密封结构，采用三只o形密封圈设计，与传统闸阀的填料密封结构相比，道道密封紧密，磨擦阻力大幅减少。在阀门处于任何开度、有压力且具备阀杆锁定功能，确保在操作和维护过程中阀杆不会被压力冲出，避免造成人员伤害。

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.

紧凑的结构，使大工作高度较传统闸阀降低60mm-300mm以上，节省工程空间；本体采用球墨铸铁材料，重量较传统闸阀减轻约20%-30%，安装维修便利。

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.

阀体内部以环氧树脂涂装，阀芯内外表面以橡胶*包覆，不会出现锈水或腐蚀现象，可直接用于生活饮用水系统、食品医药行业。

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.
