Yuhuan County Bureau of Quality Supervision has spread, the new valve started the implementation of the national standard in 2009, business organizations should pay attention to the light of the new production standard, otherwise it will result in product failure.

     The valve industry, introduced new standards for the production of the affected? Some business owners said that many companies already know the standard to be introduced, began preparations in advance, so the implementation of the new standards do not impact on enterprises; the other hand, a lot of market share in the production of large enterprises in the technology is already mature fully meet the new standards with conditions. At present, many large enterprises have been produced in line with the new standard valves, which act to regulate the industry and create a favorable market environment is very favorable, and most likely to be the new standard, “stab” and can only be that price, illegal production of small enterprises, smaller brands.

     County Bureau of Quality Supervision, according to the person in charge, “iron and copper thread connection valve” (GB/T8464-2008) of products made by more stringent requirements. The “iron and copper thread connection valve” to define the shape no matter in what way valve, valve size of the minimum wall thickness values are nominal pressure, nominal diameter to be confirmed; increase in stem diameter minimum requirements, anti – torque performance, and anti-bending performance, etc.; used for drinking water pipe valve also increases the health performance requirements.

     Manufacturers how to use industry-standard products to control production, to produce products that meet the standards, it would require the production must be carried out according to certain specifications, the product meet the standard requirements or the rate of compliance depends mainly on the conscious corporate behavior, because the quality inspection department of the test data only reflects the status of the product itself censorship, the general situation of how the company’s products entirely by enterprises in production, how to control.

     For an enterprise, standardize the technology and the law of production is the production of standardized prerequisite and foundation for enterprises in the production, management and operation in the implementation of the standards to international standards, the criterion used by the enterprise to shorten the gap, improve production efficiency, improve product quality, make the product into the international market, to get a good cost-effectiveness must strive towards, is that the enterprises with the international market in the only way.

More recently, Zhejiang and Jiangxi Iron Valve Co., Ltd., based on years of design experience to develop a two-way flow valve is a combination of head-rotating valve of the superior sealing performance and structural performance advantages of butterfly independent research and development, and has successfully developed the most elaborate sexual the highest bid was a new ball, with two-way valve seals, adjustable, long life and practical advantages, but also have the butterfly small size, light weight characteristics of the structure of benefits.

Most of the original pipe network system valves are mainly used to cut and regulation of the media, this part of the valve throughout the system share of major, dosage and more demand valve durability, cost-effective, and should be able to forward flow in the medium to conduct regulation and set off, in the pressure change or overhaul Shi You can prevent back flow medium, namely, has a bi-directional cutting capabilities. Now, this part of the valve in the pipe network system, major applications are cut-off valves, gate valves, butterfly valves and ball valves. Cut-off valves and gate valves, with good function of the bi-directional cutting and sealing performance and service life are good, both ancestor of one of the valves, but the cut-off valve by the cut-off gate-type structure inherent limitations, form large operating torque large to produce large caliber, the largest caliber on the market today, only DN400; valve had no regulatory function, there used to regulate flow of a substantial risk of falling gate defects, while the large-diameter valve the same shape and height of its large, in the manufacturing and transportation the difficulties.

With this, butterfly compared with the valve opening and closing time is short, the operation torque is small, installation space features such as small and light weight, some of the division of labor instead of using butterfly valve. But all along, butterfly valve sealing performance does not fully meet the market requirements, in addition to the center line rubber lined butterfly valve can be within a certain pressure range two-way seal, the other structures essential for the one-way flow. Midline structures are rubber restrictions are not universal. Improved, the market appeared on flexible stainless steel sheet structure of the two-way valve, but its high price. Currently mainly used in petroleum, natural gas, gas pipeline and other media, the more important, in general, pipe network, especially the application of very small water systems.

Zhejiang and Jiangxi Iron Valve Co., Ltd., based on years of design experience in the successful development of the most compact, cost-effective new ball, its structure is semi-eccentric butterfly valve structure! Sealing principle, combined with a fixed front-end ball valve sealing and eccentric butterfly valve sealing force, thereby achieving high and low voltage bi-directional cutting.

The new product also has a lot of excellent performance: The Sealing of the two sealing surface hardness according to the different needs of the application of space plasma spraying, Ethernet laser ablation, vacuum infiltration to protect the heap and other advanced technology to form complex martensitic stainless steel, austenitic stainless steel, carbide, metal ceramics, functionally gradient materials such as synthetic diamond. Automatically on the center of (adaptive), automatic compensation for wear and tear process more automatic than to be a high sealed pressure, instant off, instant open friction between the seal pair, open the spool when the ever-expanding and forward projection, the structure a short, small size , can produce large-caliber, large caliber, large caliber, large diameter valves, transportation, installation, maintenance overhaul convenient, reliable operation and a series of advantages, as the valve industry, a major technological revolution.
