Large diameter all welded ball valve quality features large diameter welded ball valve characteristics


1): No maintenance, adjustment and lubrication, easy installation, long-term reliable operation at low operating costs. The surface is spray-coated and has a beautiful luster and is at the leading level in China. There will be no external leakage. The valve body is welded, so the valve is light and easy to insulate. Installation of the adjustment mechanism is very simple, the operating handle can be removed and reversing.


2): Since the seat is made of carbon fiber reinforced Teflon seal ring and disc spring, it has strong adaptability to changes in pressure and temperature, and does not cause any slippage within the marked pressure and temperature range.


3): The processing of the sphere has advanced computer detector tracking and detection, so the processing precision of the sphere is high.


 


4): Because the valve body material is the same as the pipe material, there will be no uneven stress, and it will not be deformed due to earthquakes and vehicles passing through the ground. The pipeline is resistant to aging.


5): Large diameter all welded ball valve, equal diameter and variable diameter channel, fixed ball and floating ball, double piston effect sealing system, automatic


Inject sealant bearings.


6): In order to prevent static electricity, the steel ball and the spring are respectively installed between the valve stem and the ball body and the valve stem and the stuffing box, which can keep the electrical conduction of all parts of the valve and the valve body, and let the current pass through the area to release static electricity. Not only prevent fires, but also prevent corrosion and achieve temporary cuts for timely maintenance.


7): The valve stem anti-off function is because the valve stem is affected by the pressure inside the valve, and the force is always generated. Therefore, the valve stem is designed to prevent the structure.


8): Use a thrust washer support with a low friction material to push the pressure against the valve stem so that the valve stem only transmits torque.
