LF2 High Pressure Top Entry Ball Valves

YFL High pressure forged steel top entry ball valves are widely installed in high pressure applications for convenient online maintenance in oil & gas production and transporoation, oil refinery, petrochemical, metallurgy and power etc.

YFL High pressure forged steel top entry ball valves technical features:

1. Top entry structure makes the ton entry ball valves can be online maintenance without removing the valve from the pipeline. 
2. One piece forged body with sufficient wall thickness and high strength bolts can stand high working pressure and can be weleded directly to the pipeline.
3. Seat with bevel angle design eliminates accumulation of impurities.
4. Realize reliable sealing through pre-load spring under zero pressure and lower pressure condition. Ensure excellent sealing performance during fire condition with additional expanding graphite.
5. When there are damages between the valve seat and ball, emergency sealing can be achieved as secondary sealing with grease injection through grease injection valve for grease gun. There is a check valve in the grease injection valve to prevent the grease from spilling under pressure from the ball valve.
6. Extended stem are available for underground buried applications
7. With Double block and double bleed design, the working medium trapped in the valve cavity can be discharged through drain and bleed valves, and the working pressure increasing in the valve cavity can be relieved automatically through seat at outlet side.
8. Less leakage point, Lower torque, lower maintenance cost and longer working life

Chiller installation technology

1. When selecting the position of the lifting point, first consider the best position of the air circulation, and secondly consider the direction of the structure of the storage body. 2. The gap between the chiller and the slab should be greater than the thickness of the chiller . 3. All the slings of the chiller should be tightened, and the bolts and slings should be perforated with sealant to prevent cold bridge and air leakage. 4. When the ceiling fan is too heavy, use the No. 4 or No. 5 angle iron as the lintel. The lintel should span across the other roof and wall panels to reduce the load.

Copper rod machine melting,Copper rod upcasting machine,Copper plating line

China is short of copper, and China is also a big copper user. At present, the copper consumption of China's cable industry is about 7.5 million tons, accounting for more than 60% of China's total copper consumption, accounting for about 1 percent of the world's total copper conductor consumption, making it the largest copper user in the world. In order to solve the serious situation, the smart Chinese people try to use the machine which could meet the energy-saving requirement to produce the cooper rod. D&S copper rod making machine adopts the advanced fire refining technology to produce the￠8MM bright low-oxygen copper rod which is meet the international standards in the continuous casting line. The features of the production line are continuous casting and rolling process. There is no interruption from melting of raw material, casting process, rolling process and delivery of product, and it has high efficiency due to automatic control throughout the entire process. ...
