中国高压阀门质量偏低仍需依赖进口

译文：
在我国目前的阀门市场上，除低压阀门达到国际市场能接受的水平外，高压阀门仍然需要依靠进口。在宏观经济持续看好的形势下，阀门行业的大部分企业生产和销售指标都保持了较快增长，但受价格战影响，行业销售收入和利润较去年同期大幅下降。随着世界经济回暖，我国阀门产品的进出口也有所增长，但由于在高端技术上与国外的厂商相比仍存在较大差距，今后一段时期内，产品技术将成为制约我国阀门产品发展的一个瓶颈。 阀门是石油、化工、电站、长输管线、造船、核工业、各种低温工程、宇航以及海洋采油等国民经济各部门不可缺少的流体控制设备。经过多年的发展，我国的阀门企业数量居全世界第一，各种大小阀门企业约6000余家，其中年产值超过500万元的有900家。BR从产品情况来看，我国阀门行业目前已经能生产十几大类产品，如闸阀、截止阀、球阀、蝶阀、安全阀、止回阀、节流阀、旋塞阀、减压阀、隔膜阀、疏水阀、紧急切断阀等，最高使用温度达到570℃，最低为-196℃，最高压力为600MPa，最大通径达到5350毫米。另外，根据相关部门统计，我国每年阀门市场成交额高达500亿元左右，其中100多亿元的市场被国外阀门企业占领。 目前，我国阀门行业仍然还存在着一些问题，如我国阀门企业主要以低层次、小规模、家庭作坊式企业为主。在产品上，由于重复投资，技术引进不够，我国阀门企业的主导产品仍然是低质量的大众产品。目前我国企业生产的各种阀门普遍存在着外漏、内漏、外观质量不高、寿命短、操作不灵活以及阀门电动装置和气动装置不可靠等缺点，部分产品只相当于上世纪80年代初的国际水平，一些高温高压和关键装置上需要的阀门仍然依赖进口。另外，我国阀门行业在产业结构、阀门工业的产业链，以及行业的专业化程度上均与国外企业存在较大的差距。 造成国内阀门产品质量低下的原因在于：由于市场急速扩大，原有国营阀门企业纷纷关停并转，虽然一批乡镇企业迅速发展，但由于乡镇企业起点低，技术力量非常薄弱，设备简陋，产品大多数都是模仿生产，特别是给排水用的低压阀门问题严重。

In China's current valve on the market, in addition to low-pressure valve to achieve a level acceptable to the international market, the high-pressure valves still need to rely on imports. Continued good macroeconomic situation, the valve industry, most of the production and sales targets have maintained fast growth, but affected by the price war, industry sales revenue and profits dropped sharply from a year earlier. As the world economy to pick up, import and export of China valve products also increased, but because of the high-end technology, compared with PT-2B SERIES CONTROLLING MODLEforeign manufacturers are still a wide gap between the next period of time, products, technology will be restricting China's valve products the development of a bottleneck. Valve oil, chemical, power station, long-distance pipeline, shipbuilding, nuclear industry, a variety of low-temperature projects, aerospace and marine oil and other economic sectors indispensable fluid control equipment. After years of development, China's valve number of companies ranking first in the world, businesses of all sizes around the valve more than 6,000, of which more than 5 million yuan annual output value there are 900. BR from the product point of view, China's valve industry is now able to produce more than a dozen major categories products, such as gate valve, globe valve, ball valve, butterfly valve, safety valve, check valve, throttle, plug valves, decompression valves, diaphragm valves, steam traps, emergency shut-off valve and so on, the maximum temperature reached 570 ℃, a minimum of -196 ℃, the maximum pressure of 600MPa, the PT-2E SERIES CONTROLLING MODULElargest diameter to 5350 millimeters. In addition, according to the relevant sectoral statistics, China's valve market turnover each year up to 500 billion yuan, of which more than 100 billion market by foreign occupation of the valve business. At present, China's valve industry is still, there are still some problems, such as valve company in China mainly low-level, small-scale, family-based workshop-type enterprises. In the products, due to duplication of investment, technology transfer is not enough, China's leading valve company is a low-quality products are still popular products. China's current production of various valves widespread leakage, internal leakage, appearance quality is not high, short life, the operation is not flexible and valve electric devices and pneumatic devices are notFlanged end gate valve reliable shortcomings, some of the products is equivalent to the last century, 80 beginning of the decade the international level, a number of critical devices to high temperature and pressure and the valve is still in need of dependence on imports. In addition, the industrial structure of China's valve industry, valve industry, industrial chain, and industry on both the degree of specialization and foreign enterprises there is a big gap. Create internal valve because of poor product quality: Due to rapid market expansion of the existing state-owned enterprises have Guantingbingzhuan valve, although a number of township enterprises developed rapidly, but because of the low starting point for village and township enterprises, technical force is very weak, poorly equipped , the products mostly to imitate the production, especially in low-pressure valves used in water supply and drainage problem is serious.
