Small Valve Contains Big Energy,food Valve Class Prospects Can Not Be Ingorned

Small valve, but contain big energy.Valve is one of the important tools that can not be ignored in the actual operation process of pipeli'ne management.If according to the function can be divided into shutoff valve, check valve, regulating valve, and so on, different ty'pe's of valve bearing the role is also different.Among them, the sanitary valve is mainly used for food processing, fermentation, ph'armaceutical and other clean areas.Compared with other valves, sanitary valve requirements are very strict.

Health valve is in li'n'e with the health standards (food standards or medical standards) of the valve, the body must meet the health standards of stainless' steel, all contact with the media are mirror polishing.Among them, polishing and cleanliness to meet the health standards, meet 'the valve assembly health standards.Introduce according to professional personage, this kind of valve wants to satisfy to accord 'with GMP requirement, general surface smooth degree 1.6 above, have the structure that prevents to cross material even outside' sealing face, this shows, this kind of valve mechanical sealing requirement is very strict.In other words, some common indust'rial valves can be replaced by sanitary valves, whereas sanitary valves cannot be replaced by ordinary industrial valves.

According to relevant enterprise technical personnel introduction, in numerous valves, food high pressure safety valve is playing an important role, mainly to play a protective role, not only self-protection, but also to protect the safety of operating equipment and operators.This kind of valve is automatically opened and closed according to the working pressure of the pressure system. It is generally installed in the closed system equipment or pipeline to protect the safety of the system.

The author learned that the number of enterprises that can have qualification to produce safety valve in China is not large, because safety valve belongs to the special equipment industry, the general administration of quality supervision of the state is relatively strict in the application qualification examination, so is the food safety valve.And huge safety valve demand market, no doubt to some of the ability, conditions for the production of safety valve enterprises have brought more opportunities.

We know that valves according to the material to be divided, can have cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.).Among them, the food processing field stainless steel valve application is more extensive.The author learned that in 2017, China's stainless steel valve market development.Valve manufacturing industry in the first half of the cumulative industrial output value of more than 54,888 thousand yuan, up 45% compared with the same period last year;Realized the cumulative product sales revenue of 5.2 billion yuan, an increase of more than 30% over the same period of last year;The total profit was 3.9 billion yuan, up 27% over the same period last year.

However, as far as the stainless steel valve market is concerned, there are still some problems.On the one hand, some manufacturers in order to pursue interests to buy inferior valves, product quality can not be guaranteed, also on the peer qualified valve enterprise reputation caused a certain impact.On the other hand, a small number of manufacturers through the waste valve repaint after secondary sales, to food production and processing brought serious safety risks.Over the years, many boiler explosion incidents, no doubt most of the valve (safety valve) quality unqualified, improper use or lack of maintenance caused by, once the accident will cause huge economic losses, even life safety, environmental damage.

The author from the several opinions about accelerate the development of the equipment manufacturing industry, and China association and relevant state departments have been put forward for the "15", during the period of "11th five-year plan" gradually realize the valve of major equipment localization plan, by introducing the key technology and independent development, improve the sci-tech contents in the valve, to ensure product quality.And in the regulations and policies to give a lot of preferential treatment, which also gives the valve production enterprises to actively do a good job for the country to provide policy support for the valve industry.

Therefore, the author suggests that, in food production and processing, enterprises not only need to select suitable functional valves, important to choose a quality assurance valve, which determines whether the related mechanical equipment can operate normally.When healthy valve of choose and buy, must look for professional and qualified manufacturer of healthy valve, cannot coddle small and cheap to buy fake and inferior product, avoid to cause needless loss
