The activities of the Asia-Pacific Natural Gas Vehicle Tour and the Shangchai Power Environmental Protection Tour in China with the theme of "Leading in environmental protection and driving a better life" have just ended. Shanghai Diesel Engine Co., Ltd. (hereinafter referred to as "Shangchai") - the main driving force of this traditional construction machinery The suppliers also presented BICES 2009 in a "technology, quality, and service" posture. Shangchai is committed to supporting the construction machinery industry for nearly 60 years. It is one of the most powerful diesel engine manufacturers in China. The first loader, the first bulldozer, and the roller manufactured in China are all equipped with Shangchai engines. At present, the matching power of Shangchai's domestic construction machinery products ranges from 73.5kW to 257kW (100 to 350 horsepower), and the supporting coverage rate is over 60%, including loaders, bulldozers, graders, cranes, road rollers, and pavers. Air compressors, pump trucks and other construction machinery. In 2009, the theme of BICES 2009 was "Safety, environmental protection, and technological innovation." This was largely in line with the three core competencies of "technology, quality, and service" built by Shanghai Diesel, and Shang Chai's participation in this event It is also "technology, quality, service." At the time of the industry event, Shangchai also exhibited three products, including D9, SC8DK, and SC9DF, which are the most competitive in the field of supporting power engineering machinery. The D9 diesel engine that meets the national second-stage non-road emission standards has a practical application power of 162 to 257 kW (220 to 350 hp) and has good reliability. This product adopts piston oil cooling technology and alloy bainite cylinder liner, the lowest fuel consumption is 195h/kW·h, and the economy is better. It is the main power of the current 50 loaders in China. As the earliest domestic development and application of the State III products, the SC8DK/SC9DK electronically controlled diesel engine has inherited the superior fuel economy of Shangchai Engine. At the same time, the products are more mature and reliable. The domestic 16 to 25t truck crane market has an 80% market share, and it has won Europe. Non-road machinery Phase III emission certification. At present, the product is being gradually tested in the domestic loader market. The SC9DF diesel engine is a reference to the North American heavy-duty diesel engine R&D and testing process, and is jointly developed with the Southwest Research Institute of the United States. The product was awarded the title of “Designated Environmental Protection Engine for Shanghai World Expo 2010â€. The country's IV products have been partially applied to public transport vehicles, which has provided Sichai with technology and product reserves for further expanding its market share in the 50-75t truck crane market. High quality comes from high-quality products, high-quality services, and innovative technologies. In the past 60 years, Shanghai Diesel has relied on the advantages of the construction machinery industry to continuously carry out technological innovations and professional breakthroughs, upgrading from machinery to electric control, and progressing from the State II to the State IV standard, with mature and stable power, innovative and environmentally friendly expertise, and reliability. , Safe product performance advantages for the construction machinery industry to provide high-quality power. At the same time, Shangchai launched a new "Easy + People" service. Fast, professional, and truthful is the commitment of Shangchai to users. As the first company to launch a service brand in the industry, Shangchai provides full-service services to its customers with professional service, genuine service attitude and extensive service network. As early as two years ago, Shang Chai decided on the strategic idea of ​​vigorously developing commercial vehicle power accessory products and stably developing the power of construction machinery. Shangchao needs to walk on two legs and develop healthier. In the future, Shanghai Diesel will continue to provide dedicated power for construction machinery products and continue to devote to the research and development of more economical, environmentally friendly, and more efficient diesel engines suitable for construction machinery products.
Double-eccentric metal-to-metal
sealed Butterfly Valve
Summary:
Flange double-eccentric metal-to-metal sealed butterfly valve is
operated by worm gear to decelerate to drive the disc to rotate within 90°.It can be applied to cut off or
regulate the flow of media. The valve can be actuated by operating lever,
handle wheel, electric actuator or pneumatic actuator. Underground valve can be
operated by an extended Spindle. No matter operated by electric actuator or
pneumatic one, positions where the valve is opened and closed are all equipped
with limit switches and indicating devices that synchronically show the opening
state of the disc.
Structure:
Being double eccentric, when opened, the
sealed ring of the disc is automatically off-seated after only a little degree
of opening movement. The sealed ring completely bears no external pressure,
which helps the valve keep longer life.
Butterfly valve has the capability of
bi-directional sealing, which achieves no leakage in both primary and secondary
directions, especially applicable to underground water-supplying network of
pipes with circular multi-sources. If only unidirectional media, when
installing the valve, the primary direction is of priority.
The position of sealed ring can be
adjusted in all directions to modulate the compression of the sealing, which
makes the valve able to be operated by minimum torque.
The base ring of the body and the
sealed ring of the disc all employ stainless steel of excellent quality, which
are competent of high temperature and anti-corrosion and long service life. The
sealed structure of the valve uses divided-body design, dependable interchangeability,
easy to apply and maintain.
As to those valves whose DN is
equal or larger than 1200 mm,
the disc applies the flying-disc design with a result of light weight, high
rigidity, powerful strength, small flow–resistance and Low loss of pressure.
The stem and disc use a
positioning pattern of non-penetration and pin–offset to avoid shearing and
abrasion of the spline caused by frequent shifting of the upper stem and to
prevent abnormal opening and closing of the valve.
Between the stem and the body [o"
ring , a kind of environmentally-protecting rubber is applied, which not only
achieves no maintenance but also reliable sealing, meanwhile, overcomes
potential leakage when stuffing and sealing as well as prevents stuffing`s pollution
of the water.
Technical
characteristics:
Automatic assembly and coating
product line and developed process-flow ensure the outstanding ability of
anti-corrosion and flawless appearances of products.
Anti-corrosion
performance:
Inside and outside surfaces of the
body are coated with electrostatic epoxy resin powder. The coating is even and
firm with good adhesion and excellent anti-corrosion.
Sanitary standard:
Non-toxic epoxy resin powder used
comply with EN sanitary standard.
The
coated resin is in accordance with standards of potable water
Applying area:
The valve can be used in potable
water system, water supply and drainage, heat supply, gas,
metallurgical industry, energy system and pipeline and so on.
