1. Introduction.
Thermopiping ball valves are a commonly used type of valve, which is mainly used to control the flow of media in thermopiping. Its working principle is to open or close the pipeline through the rotation of the sphere, which has the advantages of simple structure, convenient operation and good sealing performance. Thermodynamic pipeline ball valves are widely used in heating, air conditioning, refrigeration, water treatment and other fields.
Second, the importance of maintenance and maintenance.
In the process of long-term use, due to the influence of medium temperature, pressure, corrosion and other factors, the ball valve of thermal pipeline is prone to wear, aging, leakage and other problems, which will not only affect the normal operation of the equipment, but also cause potential safety hazards. Therefore, regular maintenance and maintenance of the ball valve of the thermal pipeline is an important measure to ensure the normal operation of the equipment.
3. Maintenance and maintenance skills.
Check the appearance: Regularly inspect the appearance, including the valve body, valve stem, handle and other parts, to see if there are cracks, rust, wear and other phenomena. If there is a problem, it should be repaired or replaced in time.
Clean the inside: After closing the ball valve, remove the valve cover regularly to remove impurities and dirt inside. Note that during the cleaning process, do not use strong acid and alkali cleaners, so as not to cause damage to the sealing material of the valve.
Switch test: Regularly conduct a switch test on the ball valve of the thermal pipeline to ensure that the valve has no jamming or abnormal sound during the opening and closing process. If there is any abnormality, the parts should be adjusted or replaced in time.
Lubrication: Regularly fill the bearings and rotating parts of the ball valve with lubricating oil to ensure smooth valve opening and closing. At the same time, it is necessary to regularly check whether the lubricating oil is sufficient to prevent the valve from jamming or wearing due to lack of oil.
Tighten the bolts: Regularly check and tighten the bolts of each part of the valve to ensure that the valve will not leak or fall off due to loose bolts during use.
Replace the sealing material: For some valves that need to use sealing materials, such as rubber sealing rings, etc., they should be checked and replaced regularly. The performance of the sealing material will degrade over time, so timely replacement can guarantee the sealing performance of the valve.
Corrosion prevention: For some materials that are susceptible to corrosion, such as stainless steel, corrosion protection should be carried out regularly. The valve can be protected by applying rust inhibitor or using other anti-corrosion materials.
Record maintenance information: After each valve maintenance, the content, time, problems found and other information of the maintenance should be recorded in detail, and a complete maintenance file should be established. This not only facilitates future maintenance work, but also allows potential problems to be identified and resolved in a timely manner.
IV. Conclusions. The maintenance and maintenance of the ball valve of the thermal pipeline is an important measure to ensure the normal operation of the equipment. Through reasonable maintenance and maintenance, it can effectively extend the service life of the valve, reduce the incidence of equipment failure, and improve the operation efficiency of the equipment. At the same time, it can also ensure the safety performance and stability of the equipment, and avoid safety accidents caused by valve problems. Therefore, relevant personnel should fully realize the importance of the maintenance and maintenance of the ball valve of the thermal pipeline, and operate and maintain it in strict accordance with the regulations to ensure the normal operation of the equipment.
