factory customized Dual Check Valve Backflow Preventer - Fluorine-lined stainless steel/cast steel national standard globe valve – JUGAO VALVE Detail:
Product Description
Basic structure of globe valve
1. Globe valve refers to the closing parts (disc) driven by the valve stem and along the center axis of the valve seat for lifting movement of the valve, in the pipeline is mainly used to connect or cut off the medium in the pipeline, but can not do throttling.
2. Fluorine plastic fully lined J41F46 straight-through type, J45F46 straight-flow type, J44F46 cutin type stop valve, has the advantages of compact structure, flexible opening and closing, strong corrosion resistance, short stroke (generally nominal diameter 1/4), is widely used in petroleum, chemical and other pipeline systems as truncation medium, But it should be emphasized that the fluorine plastic lined globe valve is strictly prohibited to be used as flow regulation, so as not to erode the sealing surface caused by high-speed medium flow at the throttle mouth.
3. The disc and stem are designed as one structure to prevent the possibility of internal parts rushing out of the valve body due to the pressure fluctuation of the pipeline, compact structure and safe use.
Product features
Fluorine valve has the following advantages:
1. Has the advantages of simple structure, convenient manufacture and repair.
2. Working stroke is small, open and close a short time.
3. Good sealing, the sealing surface between the friction force is small, longer life expectancy.
Fluorine valve defects are as follows:
1. Fluid resistance, force required to open and close the larger.
2. Do not apply with particles, viscosity, easy to medium coke.
3. Poor regulation performance.
