干式報(bào)警閥是干式自動(dòng)噴水滅火系統(tǒng)的重要組成部分,，它是系統(tǒng)控制閥,，用于接通或切斷供水，輸出報(bào)警水流,。平時(shí)處于常閉狀態(tài),，失火時(shí)自動(dòng)開(kāi)啟，是常見(jiàn)的消防器材,。下面
川消小編來(lái)為您講解有關(guān)事項(xiàng)：
The dry alarm valve is an important component of the dry automatic sprinkler system, which is a system control valve used to connect or cut off water supply and output alarm water flow. Normally in a normally closed state and automatically opens in case of fire, it is a common firefighting equipment. Below, the editor of Chuanxiao will explain the relevant matters to you:
信號(hào)閘閥
Signal gate valve
信號(hào)閘閥的啟閉件是閘板,，閘板的運(yùn)動(dòng)方向與流體方向相垂直，閘閥只能作全開(kāi)和全關(guān),不能作調(diào)節(jié)和節(jié)流,。
The opening and closing component of the signal gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.
信號(hào)閘閥在特制手動(dòng)閘閥的基礎(chǔ)上加設(shè)電信號(hào)裝置而成,，閥門(mén)除了按標(biāo)準(zhǔn)設(shè)計(jì)制造外,，并按此閥在自動(dòng)噴水滅火系統(tǒng)中安裝及使用特點(diǎn)，采用不銹鋼精磨閥桿及便于維護(hù)的特種盤(pán)根密封,，并增設(shè)了獨(dú)特的O型圈閥桿上密封(倒密封)結(jié)構(gòu),，能確保閥門(mén)長(zhǎng)期處于常開(kāi)狀態(tài)下，閥桿不滲漏,，有利于吊頂中安裝使用,。
The signal gate valve is made by adding an electrical signal device on the basis of a specially designed manual gate valve. In addition to being designed and manufactured according to national standards, the valve is also installed and used in automatic sprinkler systems according to the characteristics of this valve. It adopts stainless steel precision grinding valve stems and special packing seals that are easy to maintain, and a unique O-ring valve stem upper sealing (reverse sealing) structure is added to ensure that the valve is in a normally open state for a long time without leakage of the valve stem, It is beneficial for installation and use in suspended ceilings.
信號(hào)閘閥工作原理：電信號(hào)裝置為全封閉精密機(jī)電盒式結(jié)構(gòu)，盒內(nèi)采用不銹機(jī)件及進(jìn)口電氣元件,，裝置設(shè)于操作手輪下方不易被碰撞的閥體壓蓋上,。內(nèi)設(shè)微動(dòng)開(kāi)關(guān)及其推動(dòng)機(jī)構(gòu)，以齒輪與固定在閥桿上的齒輪嚙合傳動(dòng),，當(dāng)轉(zhuǎn)動(dòng)手輪啟閉閘閥的同時(shí),，信號(hào)裝置便輸出對(duì)應(yīng)閘閥啟閉位置的“通”、“斷”電信號(hào),。
Working principle of signal gate valve: The electrical signal device is a fully enclosed precision electromechanical box structure, with stainless components and imported electrical components inside the box. The device is located on the valve body gland that is not easily collided under the operating handwheel. Equipped with a micro switch and its pushing mechanism, the gear is meshed with the gear fixed on the valve stem for transmission. When the handwheel is turned to open and close the gate valve, the signal device outputs the "on" and "off" electrical signals corresponding to the opening and closing positions of the gate valve.
信號(hào)蝶閥
Signal butterfly valve
信號(hào)蝶閥一般安裝在兩個(gè)部位：樓層水平干管水流指示器前端,；主干管濕式報(bào)警閥前端。
The signal butterfly valve is generally installed in two parts: the front end of the water flow indicator for the horizontal main pipe on the floor; Front end of wet alarm valve for main pipe.
樓層水平干管安裝信號(hào)蝶閥的作用,，一是當(dāng)樓層噴啉系統(tǒng)需要維修時(shí),，關(guān)閉此閥，打開(kāi)末端放水,，放空本樓層噴淋系統(tǒng)內(nèi)的水,，進(jìn)行維修；二是噴淋系統(tǒng)內(nèi)是不允許無(wú)水的,，當(dāng)這個(gè)蝶關(guān)閉時(shí),，會(huì)傳輸一個(gè)信號(hào)給消防報(bào)警系統(tǒng)，消防報(bào)警系統(tǒng)接收一個(gè)監(jiān)視信號(hào)（所以叫信號(hào)蝶閥）,，提示這個(gè)樓層的消防噴淋系統(tǒng)是無(wú)水狀態(tài),，應(yīng)快速維修。
The function of installing a signal butterfly valve on the horizontal main pipe of the floor is to close this valve when the floor spray system needs maintenance, open the end drain, and empty the water in the spray system of the floor for maintenance; The second is that there is no water in the sprinkler system. When this butterfly is closed, it will transmit a signal to the fire alarm system. The fire alarm system receives a monitoring signal (hence the signal butterfly valve), indicating that the fire sprinkler system on this floor is in a water free state and should be repaired quickly.
濕式報(bào)警閥前端的信號(hào)蝶閥作用與樓層主干管蝶閥的作用差不多,，一是維修,，二是提示噴淋系統(tǒng)內(nèi)有信號(hào)蝶閥關(guān)閉，應(yīng)盡早維修,。更多相關(guān)事項(xiàng)就來(lái)我們網(wǎng)站

The signal butterfly valve at the front end of the wet alarm valve has a similar function as the main pipe butterfly valve on the floor. It is used for maintenance and reminds the sprinkler system that there is a signal butterfly valve closed, which should be repaired as soon as possible.
