How to test and install the pipeline fully welded ball valve
Pipeline fully welded ball valve (Buried fully welded ball valve) should be installed before the pressure test to ensure the tightness of the valve itself and security.
1. fully welded ball valve test:
(1) Strength test: strength test using water as medium; welding sleeves on both sides of the high-pressure valve - duh cap. The valve open position to 45 ℃, the injection of water into the ball valve by pressure test on the sleeves. Boost to 1.5 times the nominal pressure valve, pressure 15min; no leakage is qualified.
(2) Tightness Test: Mu-tight test using nitrogen as medium; the ball valve is closed. From the sleeves pressure test valve to inject nitrogen inside the ball. Ball pressure was raised to 1.1 times the nominal pressure, cavity pressure release valve hose Walter containers that hold water for testing. The insertion depth of 1cm; produce no bubbles within 5min qualified.
2. pipeline fully welded ball valve (Buried fully welded ball valve) installed
(1) lifting: lifting should be the correct way valve, in order to protect the valve stem, do not sling tied to the hand wheel, gear box or actuator. Protective cap sleeves at both ends of the valve before soldering not removed.
(2) Welding: Buried fully welded ball valve and trunk pipeline connection to take welding. Weld quality must meet the "disk flexor fusion welded joints radiography" (GB3323-2005) Ⅱ grade standard sheet, usually a welding and can not guarantee all qualified, so manufacturers should be required when ordering valves at both ends of the valves 1.0m long sleeves, if there is enough length of weld failure will be cut off and re-welding the weld failed when the ball valve and pipe welding, the valve should be at 100% of the fully open position, so as not to damage the valve ball welding slag splashing, while ensuring internal valve seal temperature up to 140 degrees Celsius, cooling can take appropriate measures when necessary.

Drainage valves industry trends
(1) future market growth potential
To benefit from China's rapid industrialization process, water supply and drainage valves growing size of the market downstream applications. First, the rising level of urbanization, the increasing demand for municipal water supply and drainage, led the renovation and new towns water supply system and water supply pipes, and promote the rapid development of water supply and drainage valve market. Secondly, in recent years the government increased investment in infrastructure, water industry, water conservancy infrastructure construction set off a new upsurge of drainage valves huge market demand. Again, with the environmental awareness of our population increases, government policies on energy saving is inclined to make China sewage treatment industry usher in a rapid development period. Sewage treatment industry investment rising, will also drive the demand for expanding water supply and drainage valves.
(2) large diameter, large diameter valves growing demand
As China's economy continues to develop, more and more high degree of industrialization, launched a number of large focus on hydropower and water conservancy projects such as the Three Gorges power station, Xiluodu, Xiangjiaba Hydropower Station North Water Project, Yellow River Diversion Project and so on. Drainage valves are an important part of long-distance water conveyance system, greater demand in the total project. With the network diameter and increasing trend towards development, causing all kinds of large diameter, large diameter drain valve to the demand is very strong, but China valve manufacturer, due to technical and other reasons, can not fully meet the large diameter, large caliber valve market demand. Chinese companies have been part of independent research and development and production of large-diameter and large diameter water supply and drainage valves, and used in water conservancy construction in China, but production is limited, can not meet the growing demand in the downstream market. With the future carry out more water conservancy projects, all kinds of valve products, especially the needs of large-scale and large-diameter valve diameter will continue to expand, China will further promote the development of large-diameter and large diameter valve. According to the China General Machinery Industry Association valves Branch statistics, large-diameter and large diameter valves in the field of water supply and drainage share of sales share of about 50% to 60% between 2015 market will reach 30.28 billion yuan.
(3) valve enterprise system solutions continues to increase
Drainage valves two major application areas long distance water transfer projects and municipal water projects for the valve business solutions system solutions requires capacity and product type diversity continues to increase. These projects generally take procurement bidding mode, long distance water transfer projects focus valves for water pipeline water hammer during the encounter, and other negative issues of a comprehensive settlement in the ability bidding process, which requires enterprises to have a valve problem integrated solutions capabilities, production product enough to solve the long-distance water transfer project that arise during implementation of a variety of technical problems. Municipal water supply projects focus valve business with a full range of varieties of valve production capacity in the bidding process, one-stop shopping to meet their requirements.
Thus, with a comprehensive problem solving skills as well as a full range of varieties of valve production capacity of valve business will get considerable development in these two fields.
(4) High performance valves domestically and exports will continue to increase
According to the needs and the continuous development of China's national economic development of science and technology for large-scale projects supporting the required high parameters of the valve increases. Currently, China imports mostly valve products and related key projects supporting equipment, the use of the key parts of the generally high-tech, high-parameter, new materials and the difficulty of making large valve products. With the industry conditions of equipment, technology continues to improve, China will gradually drainage valve products to high-tech, high-parameter, the development of corrosion-resistant, long-life direction. In the future, the overall level of China's valve industry will be greatly enhanced, high performance valve will continue to improve the localization, export a large number of valves will also become an inevitable development.
(5) corporate mergers and acquisitions within the industry, industry concentration is rising
Disorderly competition in the industry on the one hand so that the overall strength of weak drainage valves business survival difficult, on the other hand highlights the few industries with advanced technology, research and innovation capacity, system solutions and high-quality products, competitive advantage, these companies use its comprehensive advantages, resource integration industry, small businesses and even merger will accelerate the process of mergers and acquisitions in the industry, making the resources of the entire market to the advantage of business transfer and concentration. Through corporate mergers and acquisitions, but also to solve the industry operating inefficiencies, excessive competition in the market and low-end products, excess capacity and other issues, improve industrial concentration and competitiveness of industry as a whole.
(6) valve environmental requirements will continue to increase
Drainage valves pipe network construction for the majority of the urban household water and industrial water. Valve quality, environmental performance and the ability to directly affect people's daily lives and health. With the continuous improvement of people's living standards, residents are increasingly concerned about the quality of drinking water. In 2012, China promulgated the "urban water supply and drainage technical specifications" to force the pipe network end-to-quality user port implemented strict and effective supervision, corresponding to the construction of drainage network to put forward higher requirements. This requires manufacturers to improve product performance and quality, preservation, environmental protection, energy conservation and other aspects of a variety of ways, technology. For enterprise strength, strong research and development capabilities of enterprises, good use of new technology and new products of the production process, but for some simple to manufacture, the lack of core technology and technology enterprises, the company's development will bottlenecks that are out of the market.
