Ball valve structure
All-welded trunnion ball valves require no maintenance, adjustment and lubrication, easy to install and provide long-term reliable operation with low operating costs. Surface using spray processing technology, beautiful luster. There will be no external leakage and others. The body is of welded construction, so the valve is light weight and easy to insulate. Installation adjustment very simple, operating lever can be removed, and reversing installation
Ball valve action
1.No need for maintenance, adjustment and lubrication, easy installation, long-term reliable operation at low operating costs. as THE SEAT IS CONSTRUCTED OF CARBON FIBER REINFORCED TEflON RINGS AND DISC SPRINGS, IT IS HIGHLY RESILIENT TO PRESSURE AND TEMPERATURE CHANGES AND DOES NOT CAUSE ANY LEAKAGE within the indicated PRESSURE AND temperature ranges.
The processing process of the ball has advanced computer detector tracking detection, so the ball processing precision is high.
Because the valve body material is the same as the pipeline material, there will be no uneven stress, no deformation due to earthquake and when the vehicle passes through the ground, the pipeline is aging resistant.
Whole welded, equal diameter and variable diameter channel, using trunnion ball and floating ball, double piston effect sealing system, automatic injection of sealant bearing.
In ORDER TO PREVENT STATIC ELECTRICITY, A steel BALL and a SPRING installed between the stem and the ball also between the stem and the packing box, respectively, which can keep all parts of the valve and the valve body conducting, allowing the current to pass through the area and release static electricity. Not only to prevent fire, but also to prevent corrosion, to achieve temporary cut off, in order to maintenance in time.
The function of the stem is because the stem is affected by the pressure in the valve, and the total force of detachment is generated, so the stem is designed to prevent the structure of the stem.
A THRUST WASHER SUPPORTED WITH A LOW FRICTION MATERIAL PUSHES PRESSURE TOWARD THE STEM SO THAT THE STEM ACTS ONLY TO TRANSFER TORQUE.
