Product description

Parameters

Name: Venturi adjustment angle valve

Size: 2 "to 20" DN50 to 500;

Pressure: 150Lb ~ 900Lb; 1.6MPa ~ 16MPa

Temperature: room temperature ~ 538

Material: black water, ash water and slag discharge system of large system and the ash water of polysilicon

Product features: streamlined body cavity smooth, effectively avoid the impact of particle medium on the inner wall of the valve body; the balance type fluid medium self isolation self circulation processing structure, avoid a lot of pulverized coal particles into the valve stem and the packing part, effectively solves the problem caused by abrasion of the valve leakage, the overall structure is reasonable, compact and delicate balance; the guide sleeve structure and special scraper structure, prevent fouling, self-cleaning function valve, without external energy, simple and convenient; the valve seat and the valve core adopts whole sintered tungsten carbide material, the surface of the valve cavity, the outer surface of the guide sleeve spraying treatment of tungsten carbide, the hardness reached more than 89HRA, with excellent anti erosion ability, fully adapt to the high-speed flow erosion and corrosion medium, the valve greatly improves the service life of the valve; quick detachable junction The pressing seat design, easy disassembly and replacement of valve parts; valve adopts the guide part way down design, effectively prevent the lateral vibration of the valve pressure differential case; the extended design of diversion pipe seat, preventing the high-speed fluid (containing hard particles) damage the body outlet impact and cavitation caused; connect the valve and actuator by half block rotation preventing structure design, convenient mounting and dismounting, and can prevent the high velocity medium under the spool rotation, effectively prevent the spool rotation localizer. Fault displacement or shedding forms; the thrust of the pneumatic actuator, effectively improve the valve pressure poor ability.
