Occupies a large portion of the valve in the mechanical products. According to the statistics of the foreign industrial countries, the valve output value is the sum of the compressor, fan and pumps, or about 5% of the entire machinery of industrial output. As an important part of the major technologies and equipment, especially in the power, petrochemical, metallurgy, urban water supply and drainage systems, valves, but also plays a key role, and the very large amount.

At present, the valve company in China about 6,000 more than the annual output value of more than 5 million yuan, 900. Valves 3, the domestic market in nuclear technology, Hongcheng shares, Guangdong Pearl. Last year, nuclear science and technology in the main business income of 235 million yuan, Hongcheng shares the main business income of 146 million yuan, the Guangdong Pearl of the main business income of 150 million yuan. These companies, regardless of its size, or quality of products, are currently unable to compete with similar foreign companies. China\\ s valve industry about 10% of the market is occupied by foreign enterprises, the valve branch of the China General Machinery Industry Association believes that to change this situation and improve the quality of the valve is the key.

Analysis of the industry, resulting in passive valve market in China are mainly two aspects: First, the domestic valve products and imported products than there is a gap, the quality needs to be improved; localization of awareness of some users, even artificially set the threshold so that domestic enterprises in the difficult to the successful bid with foreign enterprises.

Relevant experts believe that Chinese enterprises producing a variety of valve leakage, the prevalence of endoleaks, the appearance of quality, short life, the operation is not flexible and electric valve actuators and pneumatic devices are not reliable, some products are only quite international level in the early eighties of last century. Therefore, the development of the valve industry in urgent need of development of high technological content and new products.

The experts requested that the valve industry should vigorously adopt international standards and advanced foreign standards, and strictly implement the existing national standards, reform of the existing products, updated products meet international standards in the 1990s of the last century. At the same time, the valve industry response to the casting and forging the selection of raw materials, casting process, forging process, heat treatment and other sectors to take effective measures to meet international standards in quality and appearance quality, including castings and forgings rough.

The other hand, should continue to be carried out within the leakage of research, strict machining process, and vigorously promote the new sealing materials, product key parts of the machining accuracy, extend product life, so that the phenomenon of fundamental improvement in the valve, one short and two missed \" .

The FOUNTAIN Valve Co., Ltd. was established in 2000, is the valve village – Oubei a high-tech enterprises. The company mainly produces multifunctional pump control valve, hydraulic control valves, soft seal gate valve, 15 series and a variety of specifications of the hard seal butterfly valves and other valve products are widely used in municipal water supply, wastewater treatment, petrochemical, steel and metallurgical industries for drainage or fluid control systems, the annual production capacity of 80 million.

The company was founded, the starting capital of only 50 million yuan, annual output value of less than 800,000 yuan, in 2004, the company has developed to the 50 million yuan of output value, tax 5.88 million yuan. The secret of the success of this company because of its core manufacturing and core technology development capabilities, professional, high technical content. Corporate research and development of proprietary multifunctional pump control valve to fill the gaps, the level of technology at the leading domestic level, with 12 patents and has seven times the provincial and ministerial level scientific and technological progress awards. The company is also editor of the diaphragm fast open mud valve, and three industry standard products into the series of nine national and industry standards, the valve industry in the production of the hydraulic control valve series nominal diameter, nominal pressure up to enterprise.

Looking at the domestic valve market, the valve industry has a broad space for development, experts predict, the valve market, mainly in the power industry, petrochemical, fertilizer, environmental protection and urban construction and other industries. They assert, who has good technology, who has excellent quality, who can continue to develop new products, who will be able to seize the initiative in the fierce market competition, and come to the fore.

(2) gate-shaped: the closure of parts along the vertical movement of the center seat.
3 cocks and ball: the closure of parts is a plunger or ball, rotating around its center line.
4 Swing-shaped: the closure of parts around the seat outside the axis of rotation.
5 dish: the closure of parts of the disc around the axis of rotation within the valve seat.
6 slide-valve-shaped: the closure of parts in the direction perpendicular to the channel slide.
Second, divided by type of structure are:
Plug valves, gate valve, globe valve, ball valve – open or close the flow of gas pipelines. Check valve (including the bottom valve) –

used to automatically prevent backflow of gas pipeline. Throttle – for regulating the flow of gas pipelines.
Valve – used to automatically reduce the gas pressure inside the pipes and equipment. Department of the gas through the valve

when the valve clearance, resulting in loss of resistance to pressure, to achieve the purpose of decompression.
Third, according to use, according to the different uses of the valve can be divided into:
1 breaking with: used to connect or disconnect gas pipeline, such as cut-off valve, gate valve, ball valve, butterfly valve, etc.
(2) only reuse: to prevent gas backflow, such as check valves.
3 adjusted with: used to adjust the gas pressure and flow, such as control valves, pressure reducing valve.
4 distribution with: used to change the gas flow, gas distribution, such as the three cocks, distribution valve, slide valve.
Fourth, according to drive, depending on the drive can be divided into:
1 Manual: With the hand wheel, handle, lever or wheel, etc., there is human-powered, large torque transmission when equipped with

a worm and gear deceleration devices.
(2) Electric: With the motor or other electrical device to drive.
3 air; with compressed air to drive.
5, according to connection points with the pipe, valves and pipe connections according to separable;
