Fluorine-lined Valve Manufacturers Will Help You Understand The Selection And Precautions Of Fluorine-lined Diaphragm Valves
Fluorine-lined valve manufacturer Gaojing Valve sorted. Lined Diaphragm Valve is the main accessory of the steam and condensate pipeline system, which plays the role of water blocking and exhaust. Once the fluorine-lined diaphragm valve fails, a large amount of steam will flow into the condensate pipeline, which will not only cause a large amount of heat loss, but also cause "water hammer" and damage the pipeline network; if the fluorine-lined diaphragm valve is blocked, the condensate cannot pass or the flow rate becomes smaller, then the thermal equipment cannot achieve the expected effect.
Before choosing to use the fluorine-lined diaphragm valve, you must first pay attention to the selection of the fluorine-lined diaphragm valve. Improper selection will lead to water blocking and air leakage. The selection of fluorine-lined diaphragm valves should not only consider the drainage volume, but also be determined according to the drainage volume (condensate volume) and the pressure difference before and after the valve.
When selecting a fluorine-lined diaphragm valve, the drainage volume of the fluorine-lined diaphragm valve must be based on the steam consumption of the equipment per hour multiplied by 2-3 times the drainage volume of the selected fluorine-lined diaphragm valve. Ensure that the fluorine-lined diaphragm valve can discharge condensate as soon as possible and quickly increase the temperature of the heating equipment. The discharge energy of the lined diaphragm valve is insufficient, resulting in the inability to discharge condensate in time, reducing the thermal efficiency of the heating equipment.
When selecting a fluorine-lined diaphragm valve, you cannot choose a fluorine-lined diaphragm valve with a nominal pressure, because the nominal pressure can only indicate the pressure level of the fluorine-lined diaphragm valve shell, and the nominal pressure of the fluorine-lined diaphragm valve is very different from the working pressure. Therefore, the drainage volume of the fluorine-lined diaphragm valve should be selected according to the working pressure difference. The working pressure difference refers to the difference between the working pressure in front of the fluorine-lined diaphragm valve and the back pressure at the outlet of the fluorine-lined diaphragm valve.
The selection of fluorine-lined diaphragm valves requires accurate steam drainage, high sensitivity, can improve steam utilization, no steam leakage, reliable working performance, high back pressure rate, long service life, and easy maintenance.
In the production process of heat exchange equipment, drying room, fast heat exchanger, distillation equipment, etc., rapid heating is required, and condensate is not allowed in the production heating equipment. Mechanical fluorine-lined diaphragm valves should be selected.
For steam pipelines, heating pipelines, heating equipment, and steam equipment with low temperature requirements, thermostatic fluorine-lined diaphragm valves should be selected.
High-temperature and high-pressure superheated steam pipelines and equipment should use fluorine-lined diaphragm valves specially designed for superheated steam.
