The powerlifting barbell bar is designed for athletes to perform heavy squats, bench presses and deadlifts. It feels hard and does not store elastic energy. The diameter is also thicker (29mm) than the Weightlifting Barbell Bar. Powerlifting Competition Bar / Powerlifting Training Bar / Best Powerlifting Bar / Powerlifting Bar 20 Kg SHANDONG LE REN SPECIAL STEEL CO., LTD. , https://www.sdcolddrawnsteelbar.com
The product control devices are Italian and domestic pneumatic actuators. The valve body is directly installed. The appearance is smooth and beautiful, and the operation is reliable and practical. It can realize intelligent control. Stainless Steel Pneumatic Butterfly Valve Working Principle Stainless steel pneumatic butterfly valve is used to open and close with a round butterfly plate that turns with the valve mandarin to achieve the action of the pneumatic valve is mainly used as a cut-off valve, can also be designed to have adjustment or paragraph valve and adjust the function At present, the use of butterfly valves in low-pressure medium- and large-diameter pipelines is increasing.
The main advantages of the disc valve, the structure is simple, small size, light weight, low cost, this feature is particularly significant for pneumatic disc valve, installed in the upper air channel, through the two-position five-way solenoid valve control operation is convenient, but also can adjust the flow medium. The fluid resistance is small. When the large and medium-diameter pneumatic butterfly valve is fully opened, the effective flow area is larger, and the opening and closing is quick and labor saving. The disc plate rotates 90 degrees to complete the opening and closing, because the media forces on the two sides of the rotary plate are nearly equal. The generated torque is in the opposite direction, so the opening and closing torque is small, and a good seal can be achieved at low pressure. The sealing material of the disc valve is NBR, fluorine rubber, edible rubber, and the PTFE is lining, so the sealing performance is good, among which the hard sealing disc The valve is a hard and soft laminated metal sheet with the heavy advantage of metal hard seal and elastic seal, and has excellent sealing performance at low temperature.
Stainless steel pneumatic butterfly valve product features and working principle
The product obtained a number of patents, the structure is simple and compact, universal interchangeability is good, the butterfly board has the function of automatic centering. The smooth opening and closing transition reduces the torque due to low friction. Corrosion resistant discs and seats have good anti-corrosive properties to many kinds of acid and alkali solvents. Their chemical resistance is close to PTFE, which can resist the corrosion and swelling of most acids, alkalis, salts and organic solvents.
