　 从整个阀门市场来看国内市场分新建、扩建 程项目市场，老装置维修、改造项目市场。普通阀门生产企业之间竟相压仰，无序竞争，假冒伪劣，市场很不规范，导致某些阀门生产企业在惨烈的竞争中，连年大幅度亏损。随着市场经济的发展和完善，企业受市场的影响越来越深，用户对市场产品的需求越来越高，对产品开发、生产周期的需求越来越短。 我国阀门生产三家约2300多个，能提供的阀门产品有几大类，3500多个品种，40000多个规格。 （1） 城市建筑用阀门：城建系统一般采用低压阀门，目前正向环保型和节能型方向发展。环保型的胶板阀、平衡阀及中线蝶阀、金属密封蝶阀正在逐渐取代低压铁制闸阀。国内城市建筑需用阀门多为平衡阀、软密封闸阀、蝶阀等。 （2） 城市供热用阀门：城市代热系统中，需用大量的金属密封蝶阀、水平平衡阀及直埋式球阀、因这类阀解决管道纵向、横向水力失调问题，达到节能、代热平衡的目的。 （3） 环保用阀门：国内环保系统中，给水系统主要需用中线蝶阀、软密封向闸阀、球阀、排气阀（用于排除管道中的空气）。污水处理系统主要需用软密封闸阀、蝶阀。 （4） 城市燃气用阀门：城市燃气占整个xx全市场的22%，阀门用量大，其类型也多。主要需要球阀、旋塞阀、减压阀、安全阀。 （5） 长输管线用阀门：长输管线主要为原油、成品没及xx管线。这类管线需用量居多的阀门是锻钢三体式全通径球阀、抗硫平板闸阀，安全阀，止回阀。 （6） 石化装置用阀门。 阀门产品的开发要围绕国家经济建设的重点来发展。我国“十五”经济建设的重点是能源、农业、环保工业和城建，也就是说，阀门产品的未来市场主要在电力、石化、化肥、环保和城建等行业。而这些行业，待开发或正试制但还需提高质量的阀门产品主要为： 1、 高温、高压、锻造的先导式闸阀 2、 锻钢高压大口径截止阀 3、 锻钢高压大口径止回阀 4、 金属密封、油密封AVDCO阀 5、 全焊接全通径管线球阀 6、 升降杆式球阀 7、 大口径紧急切断蝶阀 8、 全焊接直埋式球阀 9、 高性能蝶阀（ANS1 B16.104 6级,寿合达50万次以上 10、 先导式安全阀 11、 API 6A平板闸阀 12、 API 6A CHOKT2S阀 13、 控制闪（调节阀） 14、 调节疏水阀 15、 成品油用撑开式软密封旋塞阀 16、 深海油田用（3000m以下海底）闸阀、球阀 17、 高压大口径上装式球阀 18、 氧化铝高压熔出用料浆阀 19、 天然气调节装置 此外，阀门试验装置也有待进一步提高发展。 目前，尽管我国阀门行业各生产厂家正逐步加大科研和开发力度，但产品技术上的落伍，使得竞争不得力，生产的阀门品种仅能满足市场需求的70%左右。短缺的低压大口径阀门及产需矛盾在品种和材质上的高中压阀门，还有上述待开发的新产品，都需要我们的阀门企业老研实、开发、拓展。市场的竞争，永远是优胜劣汰。加快产品结构的调整，技术的更新，新品的开发，各牌的创立是企业自身生存、发展、占领市场的根基。

From the entire valve market a new look at the domestic market share, expanded agenda item the market, the old equipment maintenance, reconstruction project market. Common valve manufacturers went so far as relative pressure between the Yang and disorderly competition, counterfeiting, markets were very irregular, leading to some of the valve manufacturing enterprises in the fierce competition, substantial losses year after year. With the development of market economy and improve the enterprise by the market impact of more and more deeply, the user demand for the product on the market higher and higher, for product development, increasing demand for shorter production cycle. China's production of three is about more than 2300 valve, valve products can provide several major categories, over 3500 varieties, more than 40,000 specifications. (1) City Building valves: Urban systems are generally low-pressure valves, are currently being environment-friendly and energy-saving direction. Environment-friendly plastic sheet valve, balance valve, and the center line butterfly valve, metal sealed butterfly valve is gradually replaced by low iron gate. You need to use the domestic urban architecture, mostly valve balancing valve, soft seal gate valve, butterfly valve and so on. (2) urban heat with the valve: City on behalf of the thermal system, which requires large amounts of metal sealing butterfly valve, horizontal balancing valve and the burial-type ball valve, which are the valves to solve pipe vertical, horizontal hydraulic imbalance to achieve energy-saving , on behalf of the heat balance purposes. (3) environmentally-friendly Valves: Taiwan's environmental systems, water supply system is mainly need to use the center line butterfly valve, soft seal to the gate valve, ball valve, exhaust valve (used to exclude the air pipe). You need to use sewage treatment system is mainly soft sealing gate valve, butterfly valve. (4) The city gas with the valve: City's total natural gas market, 22% of the whole, valves use large, its type is also more. The key needs of valve, plug valves, pressure reducing valve, safety valve. (5) long-distance pipeline with the valve: long-distance pipeline is mainly crude oil, finished products and natural pipeline did not. Majority of these pipelines need to use the valve is a three-body Forged Steel Full Bore Ball Valve, anti-sulfur flat gate valve, safety valve, check valve. (6) petrochemical plant with the valve. Valve product development should focus on the focus of national economic construction to develop. China's "15" will focus on economic construction, energy, agriculture, environmental protection industry and urban construction, that is, valve products, future market, mainly in electricity, petrochemicals, fertilizers, environmental protection and urban construction and other industries. These industries, to be developed or are in trial, but needs to improve the quality of valve products are mainly as follows: 1, high temperature, high pressure, forging a pilot-valve 2, Forged high-pressure large-diameter cut-off valve 3, large-diameter high-pressure forged steel valve 4, metal seals, oil seals AVDCO valve 5, all welding Full Bore Pipeline Ball Valve 6, lift rod ball 7, large-diameter emergency cut off valve 8, full welded ball valve Buried 9, high-performance butterfly valve (ANS1 B16.104 6 level, Shou together for more than 50 million times 10, pilot-type safety valve 11, API 6A gate valve plate 12, API 6A CHOKT2S valve 13, control flash (regulating valve) 14, regulating Trap 15, refined oil with the distraction-type soft sealing plug valves 16, deep-sea oilfield (3000m below seabed) gate valve, ball valve 17, coat-style large-diameter high-pressure ball valve 18, alumina high-pressure melting out with the slurry valve 19, natural gas conditioning In addition, the valve testing equipment has yet to be developed further enhanced. So far, despite China's valve industry, manufacturers are gradually increasing the research and development efforts, but the product of outdated technology, making competition does not force, the production of valve types can only meet about 70% of the market demand. A shortage of low-pressure large-diameter valves and production and demand problem in the variety and texture on the high and medium pressure valves, as well as the above-mentioned new products to be developed, all we need to really research the old valve business to develop and expand. Competition in the market is always survival of the fittest. To speed up the adjustment of product structure, technology updates, new product development, the creation of the brand is the enterprise's own survival, development, and dominate the market fundamentals.
