December 10, 2009 to 15, with Machinery Standardization Technical Committee of national ship pipe system accessories Technical Committee of the conference in Gansu Jiuquan China Jiuquan satellite launch center in Jiuquan office, held a piping accessories Technical Committee of the fourth session of the two meeting. The meeting examined 5 national standard piping accessories, 7 piping accessories industry standards, and discussed next year's piping accessories Technical Committee standards, amendments to the project work plan. A total of 72 experts and representatives, written standards to ensure a more authoritative, meeting set up by the national marine machinery industry 15 experts large jury. Jingjia valve chairman Jin Zongzhao a line of 2 people attended the meeting, in the standard review process, described in detail to write Jingjia valve on marine automatic control valve control valve and Marine 2 industry standard, the written opinion and according to the jury of experts praise, and passed unanimously, will promote the national industry-wide use.
Automatic control valve with center and double eccentric butterfly valve two kinds of structure of ship, using the most advanced technology design. Center of self-control valve opening and closing parts through the disc-shaped butterfly plate CNC machining centers forming, in the valve body around its own axis of rotation; controlled two-way eccentric butterfly valve, seal compression of the closed, and compensation in the butterfly valve is closed, the valve seat wear convenient replacement. Sealing materials for rubber, fluorine plastic, metal hard seal etc.. The product has the advantages of compact structure, small volume, light weight, flexible operation, convenient repair, small torque, reliable sealing performance, no leakage, long service life, small coefficient of flow resistance, aging resistance, radiation resistance, durable and so on. The company developed its own product life fully automatic testing machine, the trial proved, switch life up to 20000 times, the product performance to achieve the advanced level abroad.
Automatic control valve has a fixed ball valve two kinds of structure of floating ball valve, by boat, using the most advanced technology design. Floating ball valve with elastic sealing, tight and reliable sealing, floating ball ball is driven by medium pressure, the seal without leakage. Fixed ball valve springs and medium pressure will push the ball seat double seal. The product is provided with a locking device, has the fire, anti-static, anti-stem out of the structure, compact structure, small volume, light weight, flexible operation, convenient repair, the torsion of small, good sealing performance, long service life, small coefficient of flow resistance, anti-aging, durable and so on. Ball valve and valve seat sealing surface developed by the company, the borrowing of foreign advanced elastic valve seat seal, valve opening and closing torque is small, wear resistance, such as the national standard 6 "-150Lb ball valve torque is 400N.M, and the product with 290N.M can switch. The company developed the product life testing machine, the product was more than 10000 times the test, the trial evidence, results no leakage test, the product performance has reached international advanced level.
These two valves currently no national standards and industry standards, to this, Jingjia valve manufacturing in the long-term basis, according to China State Shipbuilding Corporation ship engineering document [2008]532, by the China shipbuilding technology and Economy Research Institute and the joint development of products at the same time, preparation of these two industry standards. The preparation of this standard, so Jingjia valve technology development and on a new level, Jingjia valve has its own intellectual property rights, which marks the Jingjia valve will face a new challenge.
