The fire signal butterfly valve is installed in all kinds of water supply and drainage pipelines, especially suitable for the occasions where the two-way seal and valve body are easy to rust, and is used to control the flow and on-off of the medium. Now let's talk about the installation steps and precautions of fire signal butterfly valve.
川消消防信號蝶閥安裝步驟
Installation steps of Chuanxiao fire signal butterfly valve
1.采用微動開關信號裝置，實現(xiàn)了在控制室直接觀察閘閥的開或是關狀態(tài)；
1. The micro switch signal device is used to directly observe the open or closed state of the gate valve in the control room;
2.蝶板與閥桿的連接采用無銷釘結構，克服了有可能的內(nèi)泄露點；
2. The connection between the butterfly plate and the valve rod adopts a pin free structure, which overcomes the possible internal leakage point;
3.蝶板外圓采用球面造型，提高了密封性能，延長了閥門的使用壽命；
3. The outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve;
4.整體重量輕，安裝方便，蝸輪傳動，驅動扭矩小。
4. The overall weight is light, easy to install, worm gear transmission, and small driving torque.
Precautions for installation of Chuanxiao fire signal butterfly valve
1、蝶閥安裝前應進行以下工作：
1. The following work shall be carried out before the installation of butterfly valve:
a、仔細核對使用情況是否與本蝶閥性能規(guī)范相互符合。
a. Carefully check whether the service condition is consistent with the performance specification of this butterfly valve.
b、清潔內(nèi)腔與密封面，絕不允許有污物附著，未曾清潔前勿啟閉蝶板。
b. Clean the inner cavity and sealing surface. No dirt is allowed to adhere. Do not open or close the butterfly plate before cleaning.
c、檢查傳動裝置是否與蝶閥上法蘭連接可靠。
c. Check whether the transmission device is reliably connected with the flange on the butterfly valve.
2、蝶閥安裝后，應定期檢查，其檢查的主要項目如下：
2. After installation, the butterfly valve should be inspected regularly, and the main items of inspection are as follows:
a、蝶閥閥座以及O型密封圈是否損傷。
a. Check whether the valve seat and O-ring of butterfly valve are damaged.
b、閥板密封面的密封性能。
b. Sealing performance of valve plate sealing surface.
c、蝶閥檢修裝配后，啟閉旋轉時不得有卡阻現(xiàn)象。
c. After the maintenance and assembly of the butterfly valve, there shall be no jamming during the opening and closing rotation.
d、蝶閥檢修裝配后，應按要求進行密封性能試驗。
d. After the maintenance and assembly of the butterfly valve, the sealing performance test shall be carried out as required.
f、每次檢修后，應將情況詳細記錄以此備查考。等等。
f. After each overhaul, the situation shall be recorded in detail for future reference. wait.
