Product Name:Oxygen-specific globe valve
Product Classification:Globe valve
Product Introduction: Valve is forced closed valve, so the valve is closed, the valve must exert pressure to force the sealing surface does not leak. When the medium from the bottom of the valve into the valve, the operating force required to overcome the resistance, is the stem and packing friction and pressure from the media generated by the thrust force than the valve off the valve opening force, Therefore, the diameter of the stem to a large, otherwise the top stem bending failure occurs.
Description Parameters Size Chart Application
1, simple structure, manufacturing and maintenance more convenient.
2, the working stroke is small, open and close a short time.
3, sealing, and sealing surface between the friction force is small, longer life expectancy.
4, the valve body structure in the form of straight-through, DC-and right-angle type. Straight-through is the most common structure, but its resistance to most fluids. DC-type fluid resistance is small, used for containing solid particles or the viscosity of the fluid. Use more angled body forging, for smaller circulation, high pressure cut-off valve.

Open and close valves, force should be smooth, non-impact. Some of the impact of high-pressure valve opening and closing parts of this impact has been considered and the general cut-off valve can not wait Gang.
When the valve fully open, the reverse should be a little hand wheel so tight between the threads, so as not to loose damage.
Lines beginning with the internal dirt more, can be cut-off valve slightly parted, the use of high-speed flow of media, be washed away, and then gently closed (not closed fast, fierce closed to prevent pinching the sealing surface residual impurities ), re-open, so repeatedly, rinse the dirt, then put to work.
Globe valve
installation and maintenance should note the following:
1, the hand wheel, lever operated valves can be installed in any position in the pipeline.
2, hand wheels, handles and Wei moving body does not allow for lifting purposes.
3, the flow of media should be consistent with the direction of the arrow shown in the valve body.
