消防閥是工業和建筑管道控制的重要配件。主要產品控制精度高，特別是流量控制。目前，它廣泛應用于工業控制系統中。在使用過程中，經常會有各種各樣的問題困擾著我們
Fire valve is an important accessory for industrial and building pipeline control. The main products have high control accuracy, especially flow control. At present, it is widely used in industrial control system. In the process of use, there are often various problems perplexing us

消防器材公司的維修人員在加工或組裝過程中，受工藝影響，很可能造成電動調節閥內部泄漏。此時，主要是由于固定限位開關的動作以及控制閥在運行過程中控制介質對控制閥的不斷沖刷和作用方式，導致閥門無法關閉，造成內部泄漏。在這方面，我們主要應該調整限位開關的位置來這一現象。
In the process of processing or assembly, the maintenance personnel of the fire equipment company are likely to cause internal leakage of the electric control valve due to the influence of the process. At this time, it is mainly due to the action of the fixed limit switch and the continuous scouring and action mode of the control medium on the control valve during the operation of the control valve, which makes the valve unable to close and causes internal leakage. In this regard, we should mainly adjust the position of the limit switch to solve this phenomenon.
的消防閥調試不當導致內部泄漏。由于電控閥的控制部分故障，閥門的限位開關和過扭矩開關會導致密封面磨損或腐蝕，也會導致內部泄漏。在這方面，我們仍應努力調整限位開關。
Improper commissioning of the fire valve resulted in internal leakage. Due to the failure of the control part of the electric control valve, the limit switch and over torque switch of the valve will cause wear or corrosion of the sealing surface and internal leakage. In this regard, we should still strive to adjust the limit switch.
由于電動執行機構調零不準確，閥門無法完全關閉，出現內部泄漏。主要調整方法是手動關閉閥門，或在無法擰緊后將閥門轉回半圈，以調整調整極限。
Due to the inaccurate zeroing of the electric actuator, the valve cannot be completely closed and internal leakage occurs. The main adjustment method is to close the valve manually or turn the valve back half a turn after it cannot be tightened to adjust the adjustment limit.
通過向下推關閉閥門。如果執行機構的推力不夠大，閥門將無法完全關閉，并會發生內部泄漏。主要方案是更換高推力的執行機構。
Close the valve by pushing down. If the thrust of the actuator is not large enough, the valve will not be fully closed and internal leakage will occur. The main solution is to replace the actuator with high thrust.
