如今，在消防工程中，消防信号蝶阀的使用越来越广泛，但有时施工安装方在安装、施工、调试过程中偶尔会出现投诉。投诉内容基本是无信号、长信号等情况。让我们找出以下情况。

Nowadays, in fire engineering, fire signal butterfly valve is used more and more widely, but sometimes the construction and installation party will occasionally complain during installation, construction and commissioning. The complaint content is basically no signal, long signal, etc. Let's find out the following.

消防信号蝶阀的信号是通过微动开关触点的通断原理实现的。微动开关本身质量问题导致的信号蝶阀故障可能会出现，但产品不合格的概率很低。要判断是否是微动开关的质量问题，简单的方法就是用万用表测量，看看微动开关的阻值。

The signal of fire signal butterfly valve is realized through the on-off principle of microswitch contact. The signal butterfly valve failure caused by the quality problem of the microswitch itself may occur, but the probability of product failure is very low. To judge whether it is the quality problem of the microswitch, a simple way is to use a multimeter to measure and see the resistance value of the microswitch.

测量人员可以先用电表测量焊接连接的微动开关的一对触点，记录电阻值，然后用手指按动微动开关的触点簧片，然后测量这对触点，如果电阻值有变化，则可以判断微动开关功能正常，质量没有问题。如有必要，重复测试几次以进行验证。

The measuring personnel can first measure a pair of contacts of the microswitch connected by welding with an electric meter, record the resistance value, then press the contact reed of the microswitch with his finger, and then measure the pair of contacts. If the resistance value changes, it can be judged that the microswitch function is normal and the quality is OK. If necessary, repeat the test several times to verify.

如果能验证微动开关功能正常，阀门启闭信号仍不输出，则可考虑信号蝶阀启闭是否到位。无论是通过移动手柄来开启和关闭阀瓣的信号阀，还是通过涡轮蜗杆驱动开启和关闭阀瓣的信号阀，都是通过改变凹形凸轮的距离来实现信号输出的。

If it can be verified that the microswitch function is normal and the valve opening and closing signal is still not output, it can be considered whether the signal butterfly valve is opened and closed in place. Whether the signal valve of the disc is opened and closed by moving the handle or the signal valve of the disc is opened and closed by driving the worm, the signal output is realized by changing the distance of the concave cam.

使微动开关的触点打开和关闭。因此，遇到这种现象后，施工调试人员可以用万用表在信号阀全关或全开的情况下进行测试。如果电阻表还是没有变化，打开信号蝶阀传动部分的防尘盖，观察凹形凸轮转动时凹形凸轮与微动开关簧片的接触距离。

Open and close the contacts of the microswitch. Therefore, after encountering this phenomenon, the construction and commissioning personnel can use a multimeter to test when the signal valve is fully closed or fully open. If the ohmmeter still does not change, open the dust cover of the transmission part of the signal butterfly valve and observe the contact distance between the concave cam and the reed of the microswitch when the concave cam rotates.

可能由于搬运、运输、安装操作不当，以及外力，如碰撞、振动等，使微动开关的距离发生偏移和变化，导致接触不良。如果确认微动开关的距离偏移发生变化，调整固定微动开关的两个小螺丝，适当调整微动开关的距离。凹形凸轮体随凹凸面移动，使微动开关的触点随着凹凸面的变化而被按下（接通）或释放（断开）。

The distance of the microswitch may shift and change due to improper handling, transportation and installation, as well as external forces, such as collision and vibration, resulting in poor contact. If the distance offset of the microswitch is confirmed to change, adjust the two small screws that fix the microswitch and adjust the distance of the microswitch appropriately. The concave cam body moves with the concave convex surface, so that the contact of the microswitch is pressed (connected) or released (disconnected) with the change of the concave convex surface.

川消小编提醒您微动开关本身的问题或微动开关与凹形凸轮接触距离造成的原因除外。应更加注意信号输出或显示系统的质量，因为信号输出显示系统的故障率普遍较高。如果这部分出现问题，应该对症处理，不需要考虑信号蝶阀的问题。

Chuanxiao Xiaobian reminds you of the problem of the microswitch itself or the contact distance between the microswitch and the concave cam. More attention should be paid to the quality of signal output or display system, because the failure rate of signal output and display system is generally high. If there is a problem in this part, it should be treated symptomatically, without considering the problem of signal butterfly valve.
