通過城鎮(zhèn)民用燃氣安全聯(lián)鎖設(shè)計，對民用燃氣系統(tǒng)中燃氣泄漏及時報警并聯(lián)鎖切斷供氣線路控制閥門，避免引起火災(zāi)、爆炸等重大事故的發(fā)生。以新建生產(chǎn)指揮中心廚房操作間為項目背景的條件下，進行安全連鎖設(shè)計。安全聯(lián)鎖設(shè)計通過可燃氣體報警器、報警控制器、切斷閥等3種儀表實現(xiàn)聯(lián)鎖報警功能，安全聯(lián)鎖設(shè)計主要包括：儀表選型、設(shè)計注意事項、聯(lián)鎖控制等3部分內(nèi)容。對城鎮(zhèn)民用燃氣進行安全聯(lián)鎖設(shè)計，大大降低了由于燃氣泄漏發(fā)生重大事故的概率，為以后同類設(shè)計提供了借鑒。

　　Abstract:

　　By urban household fuel safety interlock design， gas system， gas leak civil timely warning and cut off the supply lines interlock control valve， to avoid fires， explosions and other major accidents. Design of the safety chain in kitchen command center to operate new production for the project between the background conditions. Safety interlock design by combustible gas alarm，alarm control and shut-off valve interlocking three kinds of instruments to achieved the alarm function， safety interlock design include: instrument selection， design considerations， control of three interlocking parts. Design of urban household fuel for safety interlock， greatly reduces the gas leakage probability of a major accident， provided a similar design for the future reference.
