It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

The so-called electric means that it will move when there is electricity, and it will not move if there is no electricity.

It has an effect with your TV running out of power.

What are the faults of electric ball valves and how to eliminate them?

Let's conduct a detailed analysis, if the analysis is helpful to you, please raise your hand and give the American Vodon valve a thumbs up!

The electric ball valve is driven by an electric actuator and has a 90° rotation action, which is mainly used to cut off, distribute and change the direction of the medium. The electric ball valve has the characteristics of compact structure, stable performance and easy installation, and has been more and more used in many industries of the national industry, and can be operated on site or controlled from a distance. It is one of the last control elements in the field of automatic control.

If you choose a brand like the American Vedun VTON, if the selection is reasonable and correct, it will be more reliable, and there are few failures in the process of use, but the imported electric ball valve of the big brand is also more expensive, and many owners choose the general ** relatively cheap electric ball valve, at this time, it is necessary to analyze the common faults and treatment methods of the electric ball valve.

Fault 1: Leakage at the packing of the imported electric ball valve. Analysis of the causes:1Excessive force during operation; 2.The packing sleeve bolt is not tightened.

Ways to eliminate failures:1The normal force should be operated evenly, and it is not allowed to add casing or use other methods to lengthen the force arm. 2.Tighten the bolts that press down the packing evenly.

Fault 2: Leakage of the sealing surface of the electric ball valve. Analysis of the causes:1Closure is not in place; 2.Fouling on the sealing surface of the valve that has been closed for a long time; 3.Minor abrasions on the sealing surface; 4.The sealing surface is badly damaged.

Ways to eliminate failures:1Readjust the adjusting screws on the actuator and close them tightly in place; 2.Open a slit in the valve to let the high-velocity body wash away the dirt; 3.Re-grind and adjust the gasket compensation.

Fault 3: Leakage at the flange structure of the imported electric ball valve. Analysis of the causes:1uneven stud tightening force; 2.Aging damage of gaskets; 3.The material selected for the gasket does not match the requirements of the working medium.

Ways to eliminate failures:1Re-tighten the bolts evenly; 2.Replace the gasket; 3.Correctly select the material and form of the gasket according to the requirements of the working conditions, and contact the manufacturer if necessary to ask for help in the selection of materials. Lectotype. The requirements should be detailed when ordering.

Fault 4: Electric ball valve worm gear. Causes of worm drive bite analysis: 1Do not clean the embedded dirt, affect the lubrication; 2.Poor operation.

Fault 5: Fault analysis of imported electric ball valve electric actuator Causes: 1Poor lubrication, foreign matter stuck inside, resulting in excessive torque damage; 2.Motor failure.

Ways to eliminate failures:1Oil should be added, the packing should be pressed moderately, and foreign substances in the valve should be removed in time to keep it clean. 2.The working time of the motor should not exceed 15 minutes, and the power supply should be normal to avoid the motor being damp.

1. Motor sweeping: The gap between the stator and rotor of the motor is very small, which is easy to cause collision between the stator and rotor. Once the phenomenon of different axes of the machine base, end cover and rotor occurs, it will cause the collision between the stator and the rotor, which is often called sweeping.

The common factors that cause different axial phenomena are: serious out-of-tolerance of motor bearings, wear of the inner hole of the end cover, wear and deformation of the end cover and the stop hole of the machine base. If these phenomena are found, the bearing should be replaced, or the end cap should be replaced or brushed.

2. Motor vibration: The vibration should be distinguished whether it is caused by the motor itself, or caused by the poor transmission device, or transmitted from the mechanical load end, and then eliminated according to the specific situation. The vibration caused by the motor itself is mostly caused by poor dynamic balance of the rotor, poor bearing, bending of the rotating shaft, or different axes of the end cover, frame and rotor, or the uneven foundation of the motor installation, the installation is not in place, and the fasteners are loose.

Vibrations create noise and also create additional loads.

3. The bearing is not working properly: if the bearing is not working properly, it can be judged by experience by hearing and temperature. Touching the bearing box with a listening stick (copper rod), if you hear an impact sound, it means that one or several balls may be broken, and if you hear a sizzling sound, it means that the lubricating oil of the bearing is insufficient.

It is not easy to add too much grease, if too much will cause a lot of friction between the rotating part of the bearing and the grease and heat, the grease placed in the bearing box is about one-half to two-thirds of the total dissolution. If the bearing is installed incorrectly, the fit tolerance is too tight or too loose, which will also cause the bearing to heat up.

Type: Electric ball valve typical fault, safety valve, spring between the stem and one mounted on the actuator in its door valve reciprocating urging one of the position of the gate, which may be closed to the body, the control fluid applied to the piston in the stem in the actuator to overcome the spring force, thus maintaining in other positions usually in the open, so as the control condition is maintained for a long time, when this structure of the valve is disposed of at a large depth, and the pressure of the body is much lower than the pressure drop around the sea surface, the electric ball valve spring must be large enough, The force of closing the valve due to the pressure of the body is not enough to move the door in its failed position. It can happen in extreme cases.

This reduces the size of the actuator and increases the depth rating of the valve.

Troubleshooting: Faults by electric ball valves, which include traditional valves in this category, the valve body has a door that passes through the structure and intersects a cavity, opens and closes the cavity between the stands, and is responsible for moving the actuator between the doors of these posts. As is also the case with this type of valve, the actuator consists of a hood mounted on the valve body with a stem connected to another valve.
