Introduction to the selection of the adjustment flapper valve

For the selection of the regulating plug-in valve, high sensitivity, accurate and unobstructed steam-proof drainage, no leakage of steam, improved steam utilization, reliable working performance, high back pressure rate, long service life and convenient maintenance are the preferred conditions. With the ups and downs of the international economy in recent years, the market for regulating plug-in valves is constantly changing, whether it is regulating the plug-in valve industry or other traditional industries. The combination of online and offline Internet today makes traditional industries need innovation and transformation. . Below, let's take a look at the selection techniques for adjusting the flapper valve. Adjusting the flapper valve is based on the medium pressure, displacement, back pressure and many other factors to choose the most suitable product, the adjustment of the flapper valve must be selected, not expensive. Adjusting the plug-in valve is an energy-saving valve product, so the choice of a regulating plug-in valve, especially the high-quality regulating plug-in valve to save energy and improve production efficiency will be the purchase of regulating plug-in valve Dozens of times invested. Here, we will analyze the selection of the regulating plug-in valve for the pipes of different media, but the specific type of plug-in valve for the model and diameter should be determined according to the specific parameters. For the selection of the regulating plug-in valve, high sensitivity, accurate and unobstructed steam-proof drainage, no leakage of steam, improved steam utilization, reliable working performance, high back pressure rate, long service life and convenient maintenance are the preferred conditions. 1. In the production process of heat exchange equipment, drying room, rapid heat exchanger, distillation equipment, etc. need to rapidly heat up, do not allow the production of heating equipment with condensed water, should use mechanical adjustment plug-in valve. The mechanical type regulating plug-in valve is not affected by the change of working temperature and pressure. Water is discharged, the degree of subcooling is small, and there is no water in the heating equipment, which can make the heating equipment reach the optimal working temperature. Among them, the free float type steam regulating flapper valve has the most advanced structure and is very sensitive. The minimum subcooling degree is 0 °C, the condensed water can be discharged at a saturated temperature, and there is no steam leakage, which has the most advantages and can achieve the best working efficiency of the heating equipment. It is the ideal adjustment flapper valve for production process heating equipment. 2. In steam pipelines, heat tracing pipelines, small heating equipment, heating equipment, and steam equipment with low temperature requirements, thermostatic type regulating plug-in valves should be used. The thermostatic type regulating plug-in valve has a large degree of subcooling and a low condensing water temperature, and can fully utilize the sensible heat of the high-temperature condensed water, and the energy saving effect is good. Among them, the membrane type steam regulating flapper valve has the most advanced structure, no need for manual adjustment, and is very sensitive. The maximum subcooling has two membrane cassettes of 15 ° C and 30 ° C for selection, not afraid of freezing, small volume, and any position. Installation, can repair and replace the valve core on the pipeline, save money and labor, long service life, wide application range, is a boutique of thermostatic type regulating plug-in valve. 3. On the high temperature and high pressure superheated steam pipelines and equipment, the special adjustment plug-in valve for superheated steam should be used. The superheated steam regulating plug-in valve can separate the high-temperature condensed water generated when the superheated steam disappears under the severe conditions of high temperature, high pressure and small load. The disc type steam heat preservation type regulating plug-in valve uses the pipeline steam to heat the main steam chamber of the regulating plug-in valve, and has an advanced structure. In the case of no condensed water, the regulating plug-in valve is tightly closed, and the working quality is high, and the use is high. Long life, it is a special regulating plug-in valve for high pressure superheated steam.
