Flange ball valve is an introduction to how to classify products
How do flanged ball valves classify products? Flange ball valve standard GB/T21465-2008 "Valve terminology" is defined as: the opening and closing member (sphere) is driven by the valve stem and rotates around the axis of the valve stem. The product is not only used by an industry, but because it has many functions, it is used in a wide range, and the performance of the product is continuously improved by the development of technology. Therefore, the frequency of use is also very high.
Carbon steel worm wheel flange ball valve
Six advantages of flanged ball valve construction
1, open and close without friction
This function completely solves the problem that the conventional valve affects the seal due to the friction between the sealing faces.
2, top-loading structure
The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce the parking of the device and reduce the cost.
3, single seat design
It eliminates the problem that the cavity medium in the valve affects the safety of use due to abnormal boosting.
4, low torque design
The specially designed valve stem can be easily opened and closed with a small handwheel valve.
5, wedge seal structure
The valve is based on the mechanical force provided by the valve stem, and the ball wedge is pressed onto the valve seat to seal, so that the sealing property of the valve is not affected by the change of the pressure difference of the pipeline, and the sealing performance is reliably guaranteed under various working conditions.
6. Self-cleaning structure of sealing surface
When the ball is tilted away from the valve seat, the fluid in the pipeline passes through the spherical sealing surface at 360°, which not only eliminates the high-speed fluid scouring on the valve seat, but also washes away the accumulation on the sealing surface to achieve self-cleaning. .
Tips: The development of flange ball valve products is inseparable from the advancement of technology. Today's products are not the same, it is used by many industries. But it does not mean that it can be easily operated when it is installed and used, but it should also be carried out according to the formal instructions!
