Diaphragm Valve is to use the diaphragm as the opening and closing piece to close the flow channel, cut off the flow, and the valve body cavity and valve cover cavity separated by the cut-off Valve. The utility model has the advantages of simple structure, good sealing and antiseptic performance, small fluid resistance, and has been widely used in food, medicine, pharmaceutical and other industries.
Diaphragm Valve plays an important role in food aseptic production and processing
Diaphragm valve structure is different from the General Valve, is a new type of valve, is a special form of cut-off Valve, its opening and closing piece is a piece of soft material made of the diaphragm, the valve body cavity and the valve cover cavity and drive parts separate, is now widely used in various fields.
Whether it is the food processing industry, or pharmaceutical industry, the health environment is crucial, requiring clean, safe, pollution-free. With the continuous development of various valves for aseptic production and pollution-free production, and in food, medicine, fine chemicals and other fields have been developed. Among them, pneumatic diaphragm valve, ASEPTIC DIAPHRAGM VALVE is a very representative of the new valve.
According to the driving mode, diaphragm valve has manual, pneumatic, electric. Pneumatic diaphragm valve is a special type of cut-off Valve. With the continuous development of food and drug industry in China, more and more active exploration and upgrading of pneumatic diaphragm valve to meet the needs of market development.
Compared with other valves, the pneumatic diaphragm valve is constructed without stuffing box. The rubber diaphragm completely insulates the corrosive medium in the runner from all driving parts, so as to put an end to the usual valve “run, run, drop, leak” and other drawbacks. Because the pneumatic diaphragm valve flexibility is very strong, diaphragm closed reliable, even to the sewage can be done a good cut-off, the ultimate protection of materials from pollution.
In addition, compared with the traditional diaphragm valve, the pneumatic diaphragm valve has the advantages of double flow rate, corrosion resistance, can make the dead zone be better treated, the system is more sanitary, avoid forced turbulence, wear and noise are greatly reduced. Under the situation of energy conservation and environmental protection, the pneumatic diaphragm valve not only reduces the pressure loss, but also saves the energy by increasing the flow rate.
Compared with pneumatic diaphragm valve, aseptic diaphragm valve plays a more prominent role in ensuring safe and aseptic production. In the process of food production and processing, there is often a link to transport materials, for the flow of materials, the advantage of aseptic diaphragm valve is more significant. Due to the difficult flow of materials such as viscosity, and the general existence of poor liquidity in the process of conveying materials, easy to plug the pipeline, the pipeline will have a greater friction, and so on, so when conveying such materials, the choice of valve body for its control is particularly important.
Although the Common Butterfly Valve, ball valve is also often used to transport bulk materials, but encountered a very poor flow of materials, there will be wall hanging, blocking. Light will lead to failure to effectively close the valve, heavy production may therefore come to a standstill, and then affect the production efficiency of enterprises.
However, the emergence of Aseptic Diaphragm Valve in the market can basically eliminate the above-mentioned phenomenon, greatly reduce the production uncertainty caused by the adverse impact, thus effectively control the operation of production. In addition, it is widely used in the field of conveying powdery materials due to its flat internal structure, unobstructed conveying mode, easy disassembly and maintenance, and complete separation of operation and control system from working medium, the future holds great promise.
