消防信號閘閥是在特制手動暗桿閘閥的基礎上加設電信號裝置而成
消防信號閘閥是在特制手動暗桿閘閥的基礎上加設電信號裝置而成。閥門除了按國家標準設計制造外，并按此閥在自動噴水滅火器系統安裝及使用特點，采用不銹鋼精磨閥桿及便于維護的四氟 U 型密封，并增設了的 O 型圈閥桿上密封（導密封）結構，能夠確保閥門長期處于常開狀態下，閥桿不滲漏，有利于吊頂中安裝使用。
電信號裝置為全密封精密機電盒式結構，盒內采用不銹鋼機件及進口電氣元件裝置設于操作手輪下方不易被碰撞的閥體壓蓋上，內設微動形狀及推動機構，以齒輪與固定在閘閥啟閉位置的“通”“斷”電信號。
The fire signal gate valve is made by adding an electrical signal device on the basis of a special manual Non rising stem gate valve. In addition to the design and manufacture of the valve according to the national standards, and according to the installation and use characteristics of the valve in the automatic sprinkler system, the stainless steel fine grinding valve rod and the tetrafluoro U-shaped seal for easy maintenance are adopted, and the unique O-ring upper seal (guide seal) structure of the valve rod is added, which can ensure that the valve rod does not leak when the valve is normally open for a long time, which is conducive to installation and use in the ceiling.
The electrical signal device is a fully sealed precision electromechanical box structure. The box adopts stainless steel parts and imported electrical components. The device is arranged on the valve body glａnd which is not easy to be collided under the operating handwheel. It is equipped with micro motion shape and pushing mechanism to connect the gear with the "on" and "off" electrical signals fixed at the opening and closing position of the gate valve.
