消防信號蝶閥閥門漏水或閥門殼體破裂問題

按照標準要求，消防信號蝶閥的額定工作壓力應不低于1.2MPa，并應能承受2倍額定工作壓力的靜水壓，保持5min，試驗中蝶閥密封處應無滲漏。下面來講講
川消消防信號蝶閥閥門漏水或閥門殼體破裂問題。
According to the standard requirements, the rated working pressure of the fire signal butterfly valve shall not be less than 1.2MPa, and it shall be able to withstand the hydrostatic pressure twice the rated working pressure for 5min. There shall be no leakage at the sealing part of the butterfly valve during the test. Next, we will talk about the leakage of the valve of Chuanxiao fire signal butterfly valve or the rupture of the valve shell.
工程中偶而有用戶反應閥門關不死
Occasionally in the project, the user responded that the valve could not be closed
a、如果水質不符合要求，內有雜質或施工殘余雜質在閥門上，造成閥門關閉不到位，那就一定會出現滲漏問題，可試用沖洗的方法來。
a. If the water quality does not meet the requirements, and there are impurities or construction residual impurities left on the valve, resulting in the valve not being closed properly, the leakage problem will certainly occur, and the flushing method can be used to solve it.
b、倘若施工不注意，蝶閥兩端的連接管道同心度有偏差，也會造成蝶閥關閉不到位，造成滲漏，施工人員可重新調整管道的同心度后進行管道安裝。
b. If the concentricity of the connecting pipes at both ends of the butterfly valve is deviated due to carelessness in construction, the butterfly valve may not be closed in place, resulting in leakage. The construction personnel can re adjust the concentricity of the pipes before installing the pipes.
閥門殼體破裂
Valve shell rupture
工程中，偶爾也有用戶反映消防信號蝶閥殼體破裂，出現不能升壓或外部滲漏，該情況發生不多。毫無疑問，像這種情況只能判斷為可能在運輸途中，或是搬運、儲存、施工、安裝等環節中造成的。
In the project, some users occasionally report that the shell of the fire signal butterfly valve is broken, and there is no pressure rise or external leakage, which is rare. There is no doubt that such a situation can only be judged as possibly caused during transportation, or during transportation, storage, construction, installation and other links.
因為消防蝶閥一般安裝在離地面較高的建筑平頂下方，施工人員如果不慎跌落或出現野蠻搬運，定可造成信號蝶閥殼體破裂，畢竟普通信號蝶閥閥體是一般性的HT200鑄鐵，材料的材質比較脆，容易斷裂，所以必須小心搬運，小心輕放。
Because the fire butterfly valve is generally installed under the flat roof of the building which is higher from the ground, if the construction personnel fall down carelessly or carry it savagely, the shell of the signal butterfly valve will be broken. After all, the valve body of the ordinary signal butterfly valve is a general HT200 cast iron, and the material is relatively brittle and can be easily broken. Therefore, it must be handled with care.
When the valve body is confirmed to be broken, the valve is scrapped and can only be replaced. Of course, the responsible party shall bear the corresponding costs. If you have any questions about this, you can come to our website http://m.xintli.net Consult!
