消防信号蝶阀适用于石油、化工、食品、医药、造纸、水电、船舶、给排水、冶炼、能源等系统管路上。下面来讲讲川消消防信号蝶阀使用方法及注意事项吧。

The fire signal butterfly valve is applicable to the pipelines of petroleum, chemical industry, food, medicine, papermaking, hydropower, shipping, water supply and drainage, smelting, energy and other systems. Now let's talk about the usage and precautions of Chuanxiao fire signal butterfly valve.

消防信号蝶阀使用方法：

Application method of fire signal butterfly valve:

1、打开电器开关箱罩，根据电器控制要求把电缆的芯线接到相应的端子，并且密封好电缆进口，除此之外把电缆固定，以防止外力牵动时损坏电缆接线。

1. Open the cover of the electrical switch box, connect the core wire of the cable to the corresponding terminal according to the electrical control requirements, and seal the cable inlet. In addition, fix the cable to prevent the cable wiring from being damaged by external forces.

2、当阀门在”全关“位置时，顺时针转动下面的关向凸轮，是凸轮正好触动微动开关（可以听到咔哒声），接着旋紧凸轮上的螺钉固定凸轮。

2. When the valve is in the "fully closed" position, turn the lower closing cam clockwise. The cam just touches the microswitch (click can be heard), and then tighten the screw on the cam to fix the cam.

3、当阀门在”全台开“位置时，逆时针转动上面的开向凸轮，用与上述相同的方法调整糟糕开向凸轮。

3. When the valve is at the "full open" position, turn the upper opening cam counterclockwise and adjust the bad opening cam in the same way as above.

4、调整限位螺钉，当阀门在”全关“或是”全台开“位置时，不应使限位螺钉刚刚好顶在蜗轮的限位平面，因而应留有一定的间隙，接着自旋紧限位螺钉上的锁紧螺母。

4. Adjust the limit screw. When the valve is in the "fully closed" or "fully open" position, the limit screw should not be just pressed against the limit plane of the worm gear, so there should be a certain gap. Then, screw the lock nut on the limit screw.

5、盖上电器开关箱罩，当阀门在”全关“位置时，使开度指示器的指针指向刻度盘上的”0“刻度，并且旋紧螺钉固定指针。

5. Cover the electrical switch box cover. When the valve is in the "fully closed" position, make the pointer of the opening indicator point to the "0" scale on the dial, and tighten the screw to fix the pointer.

注意事项：

matters needing attention:

1、本蝶阀可以安装在空间任意位置管路上。

1. The butterfly valve can be installed on the pipeline at any position in the space.

2、蝶阀的安装位置应保证使用、维修与更换的方便。

2. The installation position of butterfly valve shall ensure the convenience of use, maintenance and replacement.

3、本蝶阀安装时可以不考虑管路介质流动的方向，乃允许单向流动。

3. When installing this butterfly valve, the direction of medium flow in the pipeline can be ignored, but one-way flow is allowed.

4、蝶阀安装前应存放在室内干燥处，阀板微开4°～5°。

4. The butterfly valve shall be stored indoors in a dry place before installation, and the valve plate shall be slightly opened by 4 ° ~ 5 °.

5、蝶阀安装前应进行以下工作：

5. The following work shall be carried out before the installation of butterfly valve:

a、仔细核对使用情况是否与本蝶阀性能规范相互符合。

a. Carefully check whether the service condition is consistent with the performance specification of this butterfly valve.

b、清洁内腔与密封面，不允许有污物附着，未曾清洁前勿启闭蝶板。

b. Clean the inner cavity and sealing surface, and no dirt is allowed. Do not open or close the butterfly plate before cleaning.

c、检查传动装置是否与蝶阀上法兰连接可靠。

c. Check whether the transmission device is reliably connected with the flange on the butterfly valve.

6、蝶阀在管路夹紧时，注意连接力是否皆匀可靠。

6. When the butterfly valve is clamped, pay attention to whether the connecting force is uniform and reliable.

7、蝶阀安装后，进行管路强度试压时，阀板必需处于开启位置。

7. After the butterfly valve is installed, the valve plate must be in the open position when the pipeline strength pressure test is carried out.

8、蝶阀安装后，应定期检查，其检查的主要项目如下：

8. After installation, the butterfly valve shall be inspected regularly. The main inspection items are as follows:

a、蝶阀阀座以及O型密封圈是否损伤。

a. Check whether the valve seat and O-ring of butterfly valve are damaged.

b、阀板密封面的密封性能。

b. Sealing performance of valve plate sealing surface.

c、蝶阀检修装配后，启闭旋转时不得有卡阻现象。

c. After the maintenance and assembly of the butterfly valve, there shall be no jamming during the opening and closing rotation.

d、蝶阀检修装配后，应按要求进行密封性能试验。

d. After the maintenance and assembly of the butterfly valve, the sealing performance test shall be carried out as required.
