As the carrier of fluid in
pipeline system, it is necessary to control the flow rate, pressure and flow direction of fluid. The equipment required in use is
valve. As an important part of pipeline system, the gas, liquid, gas-liquid mixture or solid-liquid mixture flowing in pipeline is of great significance. Normally, the valve consists of valve cover, valve body, valve seat, driving mechanism, opening and closing parts, seals and fasteners. It has good sealing performance, strength performance, adjustment performance, movement performance and circulation performance.
In all kinds of fluid devices, valves need to be used as control equipment. As an important part of
pipeline devices, valves play an important role that cannot be ignored. In the manufacturing process, valves need to undergo strict quality control, so as to ensure that their quality meets the use standards. However, in the process of using the valve, it is inevitable that faults will occur, which will lead to liquid leakage, not only causings equipment damage, but also increasing the cost due to liquid leakage, which affects the economic benefits of enterprises. This article analyzes the causes of valve leakage, and puts forward specific measures to prevent leakage.
In the long-term application of the
valve, it is observed that the leakage parts of the valve usually center on the packing seal, valve body and flange. Because the harm caused by
valve leakage is very serious, when the valve leaks, it is easy to cause fire, explosion and personal casualty accidents. At the same time, the life of equipment is shortened, the production of enterprises can not be carried out normally, resulting in an increase of unplanned shutdown accidents, which seriously damages the economic benefits of enterprises. Therefore, it is necessary to analyze the causes of valve leakage, so as to find out specific solutions, ensuring the safety of valve operation and creating good economic and social benefits for enterprises.
