Abstract
The utility model relates to a fluid control valve and provides a different diameter encryption soft sealing sluice valve. The different diameter encryption soft sealing sluice valve overcomes the problem that untight sealing of the different diameter encryption soft sealing sluice valve in the prior art leads to fluid leakage. The fluid leakage not only influences service life of a sluice valve, but also influences the working environment. The different diameter encryption soft sealing sluice valve comprises a valve body which comprises a through fluid inner cavity, a lower valve cover, a flashboard, a valve rod and an opening key. The lower valve cover is arranged above the valve body, the valve body is provided with a water inlet end and a water outlet end along the axial direction, the water inlet end and the water outlet end are connected with pipe fittings, the outer diameter and the inner diameter of the water inlet end are different and the outer diameter and the inner diameter of the water outlet end are different. The water inlet end and the water outlet end are provided with inner threads or outer threads, and the inner threads or the outer threads are connected with pipe fittings. The flashboard is arranged between the water inlet end and the water outlet end in the valve body in an up-and-down lifting mode. One end of the valve rod penetrates through the lower valve cover and connected with the flashboard threads which are arranged in the valve body. The opening key is movably arranged on a free end of the valve rod. The bottom of the valve body inner cavity contacts with the flashboard in a sealing mode and is a flat circumference surface. The outer side of the flashboard is covered with an elastic outer layer.
