Product Description
HG5-89-1 upspread discharge valve is mainly used for the bottom discharge of reactor, storage tank and other containers, by means of the valve bottom flange welded to the bottom of the storage tank and other containers, so eliminate the medium often in the bottom of the container residual phenomenon. Discharge valve according to the needs of the actual situation, the bottom is designed for the flat bottom, the valve body is V-shaped, and provides two working modes of lifting and lowering the valve disc. The valve body cavity is equipped with erosion resistance, corrosion resistance sealing ring, in the opening of the valve moment, can protect the valve body from being washed by the medium, corrosion, and special treatment of the sealing ring, so that the surface hardness reaches HRC56~62, with high wear resistance, corrosion resistance function. Valve disc seal according to the need of the cover are stacked with cemented carbide welding, sealing surface using line seal, to ensure the reliability of sealing, and can prevent scarring. At the same time, the design of short stroke valve disc is adopted. It is widely used in chemical, petroleum, metallurgy, pharmaceutical, pesticide, dye, food processing and other industries.
Standard Specifications
1. Design and manufacturing standard according to GB/T12235-2007
2. Structure length standard according to enterprise standard
3. Flange connection according to JB/T79-94, GB/T9113 HG20592-2009 and other
4. Test and inspection according to GB/T13927-2008
Up-spread type and down-spread type are distinguished
Discharge valves are mainly used to discharge materials at the bottom of storage tanks, reaction tanks and other containers. The valves are connected to and located at the bottom of the equipment by flange or butt welding, eliminating the residual phenomenon of process media usually at the outlet of the container. According to the needs of the actual situation, it is divided into three kinds of structural forms: upper spread type, lower spread type and plunger type; The upper type is used for the reaction kettle with agitator (in addition to the frame anchor type); And the down-spread, plunger type is used for the reaction kettle with the frame anchor type agitator. The sealing surface is made of scour and corrosion-resistant materials, and is specially treated to make the surface hardness reach HRC48 ~ 52, which has the function of high wear resistance and corrosion resistance to ensure the sealing reliability of the valve. Widely used in chemical industry, petroleum, metallurgy, pharmaceutical, dye, food processing and other industries.
