Analysis of factors for the length of valve life

First, the type of valve affects the service life Different kinds of valves have different service life. For example, ball valves and gate valves have a long service life, which can reach more than 10 years, while butterfly valves and check valves have a relatively short service life, generally about 5 years. Therefore, in the selection of different types of valves, according to the characteristics and conditions of use, the appropriate valve should be selected to prolong the service life of the valve. Second, the material of the valve affects the service life The material of the valve is also an important factor affecting the service life of the valve. Different materials of valves have different corrosion resistance and wear resistance, and the service life will also change. For example, the service life of cast steel valves is related to the carbon content and hardness of the steel, while the service life of stainless steel valves is usually longer than that of cast steel valves. Therefore, when selecting the valve material, the appropriate material type and grade should be selected according to the specific working conditions and use requirements. 3. The working medium of the valve affects the service life The service life of the valve will be affected differently in different media environments. For example, the temperature, pressure, corrosiveness of the working medium, etc., will affect the material, tightness, strength and other properties of the valve, thereby shortening the service life of the valve. Therefore, when selecting valves, the characteristics and special requirements of the medium used should be considered, and the valves with suitable materials and structures should be selected. Fourth, the use of the valve environmental impact on the service life The environment in which the valve is used is also a factor that affects the life of the valve. For example, the valve is used in some corrosive occasions, which is prone to rust and other damage, and when used in special atmospheres, such as in chemical plants, the material and performance of the valve will be higher. Therefore, when using the valve, it is necessary to pay attention to the use environment and take appropriate maintenance measures to prolong the service life of the valve. To sum up, the service life of the valve is related to many factors, such as the type of valve, the material of the valve, the working medium of the valve, the environment in which the valve is used, etc. In the actual use process, maintenance, inspection and replacement should be carried out according to the specific situation to ensure the normal operation and safe use of the valve.

Advantages of pneumatic disc valves in powder conveying

(1) Superior sealing performance: The pneumatic disc valve adopts a metal hard sealing structure, which can effectively prevent powder leakage and ensure the safety and environmental protection of the conveying process. (2) Fast switching speed: The pneumatic actuator has the characteristics of fast response speed and rapid action, which can realize the rapid opening and closing of the valve and improve the work efficiency of the powder conveying system. (3) Good wear resistance: The disc plate of the pneumatic disc valve is made of wear-resistant materials, which has good wear resistance and can adapt to the high-speed flow and particle impact in the process of powder conveying. (4) Easy maintenance: The pneumatic butterfly valve has a simple structure and is easy to disassemble and repair, which reduces maintenance costs and downtime.

The three-piece slurry valve is available with manual, electric and hydraulic options

The three-piece slurry valve overcomes the shortcomings of the conventional flat gate valve that only transports a single medium (oil or water), and has good sealing performance when it is fully open and closed, and is a new type of valve with high technology, high quality, low liquid resistance, simple structure and reliable operation. It is widely used in the slurry transportation of granular materials in mines, power plants, metallurgy, chemical and other departments, especially in medium and high pressure slurry pipelines, and is an ideal replacement valve for slurry pipelines. By the ram plate and the left and right sealing plates are composed of three pieces of valve dynamic sealing pair, all the wearing parts are concentrated in the left and right sealing plates, when the parts need to be replaced, just disassemble the left and right valve plates, it can be easily replaced, solve the problem of perforation of the gate plate of the granular mud valve, and the inconvenience of disassembly and assembly after the damage of the parts. It is divided into monolithic, two-stage and three-stage type. The valve body casting adopts the advanced technology introduced from Taiwan, with reasonable structure and beautiful shape. The valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to open and close. The stem adopts a bottom-mounted structure with an inverted seal, and the valve stem will not be impacted when the valve cavity is abnormally pressurized. The three-piece dynamic seal pair is composed of the ram plate and the left and right sealing plates, which reduces the volume of the valve cavity to almost zero. Therefore, it completely solves the problems of granular slurry valve and other old-fashioned slurry valves, which are not in place to open and close, perforated, and inconvenient to disassemble and assemble due to slurry deposition. At the same time, it also reduces the abrasion of the overflow parts, and has good opening and closing sealing, all the wearing parts are concentrated on these three plates, when the parts need to be replaced, as long as the upper valve plate is disassembled, it can be replaced at any time, which solves the problem of perforation of the granular mud valve gate plate and the inconvenience of disassembly and assembly after the parts are damaged. Depending on the pressure, manual, electric and hydraulic options are available.
