What is the resistance of stainless steel sphere to fluid? Is the seal good and the resistance small?
The sealing surface of stainless steel hollow sphere has a parallel gate valve, and the outer surface of the valve stem is peroxide treated, so it has very outstanding corrosion resistance and is also relatively wear-resistant. Stainless steel gate valve can choose all kinds of piping, in order to satisfy the need of not passing the project. The advantage of stainless steel gate valve is that the resistance to fluid is very small, and the erosion and erosion of liquid received on the sealing surface are very small. Moreover, the opening and closing of the stainless steel gate valve is also effortless, and the flow direction of the medium is not constrained, so that the pressure of the medium will not drop, and the medium will not be disturbed. The shape is very simple. Due to its good function, the scale of application is very extensive. The ball of stainless steel flanged ball valve is to rotate the valve stem to make the valve unblocked or blocked. Ball Valve switch is light, small in volume, can be made into large caliber, reliable in sealing, simple in structure, convenient in maintenance, sealing surface and spherical surface are often closed, and are not easy to be eroded by medium, it is widely used in various industries.
stainless steel flanged ball valve can be closed tightly with only 90-degree rotation and very small rotation torque. The completely equal inner cavity of the valve body provides a straight-through flow passage with little resistance to the medium. It is generally believed that ball valves are suitable for direct opening and closing, but recent developments have designed ball valves to throttle and control flow. The main characteristics of ball valve are compact structure, easy operation and maintenance, suitable for general working media such as water, solvent, acid and natural gas, and also suitable for media with harsh working conditions, such as oxygen and hydrogen peroxide, methane and ethylene, etc. The ball valve body can be integral or combined. This type of valve shall be installed in the horizontal direction of the pipeline.
product advantage: the fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length. Simple structure, small volume and light weight. Tight and reliable, the sealing surface material of ball valve is widely used in plastic and has good sealing performance, and has also been widely used in vacuum systems. Easy to operate, quick to open and close, from full open to full off as long as the rotation of 90 °, easy to remote control. Maintenance is convenient, Ball Valve structure is simple, sealing ring is generally movable, disassembly and replacement are more convenient. When fully open or closed, the sealing surface of the ball and valve seat is isolated from the medium, and when the medium passes through, it will not cause erosion of the sealing surface of the valve. Wide application range, diameter from a few millimeters to a few meters, from high vacuum to high pressure can be applied. Ball valves have been widely used in petroleum, chemical industry, power generation, paper making, atomic energy, aviation, rockets and other departments, as well as people's daily life.
