Summary of the invention
The high-performance steel lined with fluoroplastic pellet valve that a kind of moment of torsion that the purpose of this utility model is to overcome above-mentioned shortcoming and provides is little, corrosion-resistant, structure is simple, the life-span is long.
The utility model object and solve its technical problem underlying and realize by the following technical solutions:
High-performance steel lined with fluoroplastic pellet valve of the present utility model, comprise right valve barrel, spheroid, valve seat insert, left valve barrel, valve rod, this spheroid is arranged on left valve barrel and right valve barrel is inner, one end of valve rod is connected with spheroid, the other end and Stuffing box are placed in outside valve body, and valve seat insert is arranged on left valve barrel, between right valve barrel and spheroid, Stuffing box inside is filled with filler, Stuffing box upper end is provided with Gland, and Gland top is provided with driving handle.Wherein: described left valve barrel and right valve barrel inwall flow passage are arranged with backing layer, high-performance rubber O RunddichtringO is all equipped with between valve seat insert and right valve barrel, left valve barrel.
Above-mentioned high-performance steel lined with fluoroplastic pellet valve, wherein: the frame of described left valve barrel and right valve barrel adopts carbon steel to make.
Above-mentioned high-performance steel lined with fluoroplastic pellet valve, wherein: described valve seat insert is man type.
The utility model compared with the existing technology has obvious advantage and beneficial effect.From above technological scheme, described left and right valve shell body adopts carbon steel to make, and valve body internal layer flow passage is arranged with backing layer, and backing layer adopts new structural design, can high temperature resistant, resistance to vacuum, and can eliminate the impact of expanding with heat and contract with cold and bringing.Baking layer material is fluoroplastic perfluoroethylene-propylene FEP(F46), backing layer adopts single injection-molded technique, ensures its stability.On valve body, addition has Stuffing box and gland to seal, and can ensure the sealing at valve rod place, and medium can not be leaked.Valve seat insert is placed on left and right valve body and valve seat, valve seat insert adopts elastic structure design, high-performance rubber O RunddichtringO is equipped with between valve seat insert and valve seat, and its resiliently deformable auto-compensation valve seat pretightening force error can be utilized, and the impact of expanding with heat and contract with cold can be eliminated, valve seat insert and spheroid are that line style is combined closely and sealed, and possess zero leakage function, moment of torsion is little; Can be used in strong corrosive medium.In a word, the utility model structure is simple, functional, with low cost, the life-span is permanent.
