Large diameter full - welded ball valve high - quality characteristics of large diameter welding ball valve characteristics
Large diameter full-welded ball valve High-quality characteristics of large diameter fully welded ball valve Features:
1) No maintenance, adjustment and lubrication, easy installation, long-term reliable operation at low operating costs. The surface of the spray treatment technology, glossy and beautiful, has been in the leading domestic level. There will be no external leakage and so on. Welding structure, so the valve light weight and easy to carry out insulation. Installation adjustment mechanism, very simple, the operating handle can be removed, for the installation.
2) Since the seat is made of carbon fiber reinforced Teflon seal ring and disc spring, so the pressure and temperature changes to adapt to the pressure in the pressure and temperature range will not produce any leakage.
3) the ball of the processing process has advanced computer detector tracking detection, so the ball of high precision machining.
4) As the valve material with the pipe material, there will be no stress uneven, nor will the earthquake and the vehicle through the ground when the deformation, the pipeline aging.
5) Large diameter all-welded ball valve, equal diameter and variable diameter channel, the use of fixed and floating ball, double piston effect sealing system, automatic injection of sealant bearings.
6) In order to prevent static electricity, the stem and the ball and the stem and packing box are equipped with steel balls and springs, can keep all parts of the valve and the valve body conduction, let the current through the area, the release of static electricity. Not only to prevent fire, but also to prevent corrosion, to achieve temporary cut off, in order to timely maintenance.
7) stem anti-off function is because the valve stem by the valve pressure, the total out of the force so the stem is designed to anti-off structure.
8) With low-friction material thrust washer support the pressure to the valve stem, so that the stem only play the role of torque transmission.
