You may not know these common problems of electric two-way valves

1. Valve does not work

When the electric two-way valve is started, the valve sometimes does not work. When the electric two-way valve is started, the valve sometimes does not work, which may be caused by a variety of reasons. Because power failure is one of the common reasons for the valve not to move. If the motor fails, the valve will not work properly.

The mechanical part of the valve includes components such as the valve stem, valve core and valve seat. If these components are worn, stuck or damaged, the valve will not work properly. If the control circuit fails, the valve will not work properly.

In order to solve the problem of the valve not working when the electric two-way valve is started, we can take the following measures: First, check whether the power supply is normal. If the power supply fails, it needs to be repaired or replaced in time. Second, check whether the motor is working properly. If the motor fails, it needs to be repaired or replaced in time. Third, check whether the mechanical part of the valve is normal. If the mechanical part fails, it needs to be repaired or replaced in time. Finally, check whether the control circuit is normal. If the control circuit fails, it needs to be repaired or replaced in time.

In short, the problem of the valve not working when the electric two-way valve is started needs to be solved in time, otherwise it will affect the normal operation of the entire system. By checking key components such as power supply, motor, mechanical part and control circuit, we can find the root cause of the problem and take corresponding measures to solve it.

2. Inflexible valve movement

During the operation of the electric two-way valve, the valve movement is sometimes inflexible. During the operation of the electric two-way valve, the valve movement is sometimes inflexible, which may affect its normal operation. The lubrication problem of the electric two-way valve may be a reason for the inflexible valve movement. If the lubrication is insufficient, the moving part of the valve may be subject to friction resistance, resulting in inflexible movement. Secondly, the mechanical failure of the electric two-way valve may also be a reason for the inflexible valve movement. For example, the bending of the valve stem and the jamming of the valve core may cause the valve to move inflexibly. The control signal problem of the electric two-way valve may also cause the valve to move inflexibly. If the control signal is unstable or there is an error, the valve may not move correctly.

3. Flow regulation failure

The flow regulation function of the electric two-way valve is one of its important features. However, sometimes there is a problem of flow regulation failure. Among them, the most common reason is that the actuator of the electric two-way valve fails, causing the regulating valve to fail to work properly. There may also be problems with the control system of the regulating valve, such as control line failure or controller damage.

Fourth, the sealing performance is reduced

The sealing performance of the electric two-way valve is one of the key factors for its normal operation. In order to ensure the sealing performance of the electric two-way valve, by selecting suitable sealing materials, correct installation and commissioning, and daily maintenance and care, the sealing performance and service life of the valve can be effectively improved, ensuring its normal operation and extending its service life.

Five, electrical failure

The electrical part of the electric two-way valve is the guarantee for its normal operation.

Electrical failures are common problems in electrical equipment. They may be caused by a variety of reasons, such as overload, short circuit, poor contact, insulation damage, etc. These failures may cause equipment performance degradation, damage or even cause safety accidents. Therefore, it is crucial to detect and solve electrical failures in a timely manner.
