</p> <p> 消防管道一般用什么閥門(mén)？消防給水系統(tǒng)分為室外消防給水和室內(nèi)消防給水，其主要功能單元包括消防水源、消防水泵、給水管網(wǎng)、管網(wǎng)控制設(shè)備、消火栓、水泵耦合器等。 </p> <p> 消防管道一般用什么閥門(mén)？消防給水系統(tǒng)分為室外消防給水和室內(nèi)消防給水，其主要功能單元包括消防水源、消防水泵、給水管網(wǎng)、管網(wǎng)控制設(shè)備、消火栓、水泵耦合器等。消防水源可以是市政供水管網(wǎng)、消防水池、天然水源、中水等。消防泵采用自充式抽吸泵。當(dāng)消防泵直接從市政管網(wǎng)抽水時(shí)，應(yīng)在消防泵的出水管上設(shè)置具有空氣隔斷功能的防回流閥。 </p> <p> 消防水源一般采用市政給水管網(wǎng)，管道采用壓力輸水管道。閘閥、截止閥、蝶閥、止回閥、過(guò)濾器、安全閥等。通常用作閥門(mén)，也使用防回流閥。法蘭和帶槽管件是管道連接中**常用的。樓層較高時(shí)，應(yīng)設(shè)置高位消防水箱；當(dāng)潛在消防用水量大，出口壓力高時(shí)，需要分區(qū)供水。 </p> <p> 問(wèn)：球墨鑄鐵軟密封閘閥適合還是灰鐵硬密封閘閥適合消防系統(tǒng)？答：軟密封閘閥和硬密封閘閥都可以用于消防系統(tǒng)。 </p> <p> 個(gè)人認(rèn)為，軟密封和硬密封的選擇取決于介質(zhì)和泄漏率。如果是自來(lái)水軟密封閘閥，肯定更好。在自來(lái)水系統(tǒng)中，閥體材料應(yīng)選擇鑄鐵，這樣更耐腐蝕。閥體材料的選擇一般根據(jù)壓力選用灰鐵或球墨鑄鐵，消防水系統(tǒng)壓力一般在1MPa以下，因此灰鐵可以滿足使用要求，球墨鑄鐵的力學(xué)性能更好。另外，還要看價(jià)格和客戶需求。
