Abstract
The utility model discloses a maintenance-free fluoroplastic full-lining vertical check valve, relating to the field of valve structure, and particularly relating to a structure of a vertical check valve. The vertical check valve structurally comprises a valve body, a valve cap and a valve flap, wherein the upper end of the valve body is connected with the lower end of the valve cap through bolts; the valve flap is arranged in the valve body; the inside, the upper end and the lower end of the valve body are respectively provided with a same first valve body FEP (Fluorinated ethylene propylene) layer; the inside, the upper end and the lower end of the valve cap are respectively provided with a same first valve cap FEP layer; and the outer surface of the valve flap is provided with a first valve flap FEP layer. The valve body, the valve cap and the valve flap of the valve are all lined with FEP integrally, so that the sealing effect is good. According to the maintenance-free fluoroplastic full-lining vertical check valve, the use performance of the valve is reliably ensured, the sustainable operation of an equipment pipeline is ensured, the sealing performance is stable, and the problems of easiness for corrosion, poor sealing property and short service life of the previously conventional valve are solved.
Description
Technical field
The utility model relates to the structure field of valve, relates in particular to the structure of Vertical Lift Check Valves.
Background technique
In the past, the full lining safety check of chemical industry, be generally the general common valve of sealability, common valve is from material or the technique of structure and lining does not possess special-purpose characteristics, the sealability that respectively seals the position of this valve is bad on the one hand, can not well stop medium back flow; Backing layer easily peels off and leaves valve housing on the other hand, thereby causes the valve whole service life short, can not satisfy the specific (special) requirements of permanently effective conveying aggressive medium, and aggressive medium is in case leakage can bring very large harm to surrounding enviroment and personal safety.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of non-maintaining fluoroplastic all-liner Vertical Lift Check Valves of good sealing effect to be provided.
The purpose of this utility model is achieved in that non-maintaining fluoroplastic all-liner Vertical Lift Check Valves, comprise valve body, valve gap and flap, the upper end of valve body and the lower end of valve gap are bolted, flap is arranged in the valve body, in the described valve body, the upper end of valve body, the lower end of valve body arrange same the first valve body perfluoroethylene-propylene layer; In the described valve gap, the upper end of valve gap, the lower end of valve gap arrange same the first valve gap perfluoroethylene-propylene layer; The outer surface of described flap arranges the first flap perfluoroethylene-propylene layer.
The upper end of valve body of the present utility model arranges guiding groove, and the upper end of described the first valve body perfluoroethylene-propylene layer is arranged in the guiding groove.
In the valve body of the present utility model and lower end of valve body arranges respectively the valve body dovetail groove, and the second valve body perfluoroethylene-propylene layer is set respectively in each valve body dovetail groove, and each second valve body perfluoroethylene-propylene layer arranges with the first valve body perfluoroethylene-propylene layer disjunctor respectively.
In the valve gap of the present utility model and upper end of valve gap arranges respectively the valve gap dovetail groove, and the second valve gap perfluoroethylene-propylene layer is set respectively in each valve gap dovetail groove, and each second valve gap perfluoroethylene-propylene layer arranges with the first valve gap perfluoroethylene-propylene layer disjunctor respectively.
At least one through hole is set on the flap of the present utility model, the second flap perfluoroethylene-propylene layer is set respectively in each through hole, each second flap perfluoroethylene-propylene layer arranges with the first flap perfluoroethylene-propylene layer disjunctor respectively.
The lower end disjunctor of the first flap perfluoroethylene-propylene layer of the present utility model arranges up big and down small taper type boss.
The utlity model has following characteristics: 1, this valve comprises valve body, valve gap, flap etc., and valve body, valve gap, flap be whole full lining perfluoroethylene-propylene all, good sealing effect.
2, linking of valve body and valve gap adopted guide groove structure, and entirely serves as a contrast perfluoroethylene-propylene, and valve body and be built-in with equally distributed dovetail groove above the valve gap prevents peeling off of backing layer, thereby prolonged the bulk life time of valve.
3, be processed with equally distributed aperture on the flap, make backing layer and the tightly hot one that is overlying on of flap metal body of valve clack sealing surface, increased the stable and sustainability of sealability.
4, valve clack sealing surface has annular guide ledges and full lining perfluoroethylene-propylene, has guaranteed the valve accuracy that sealing pair cooperates in opening-closing process, improves sealability.
The utility model Reliable guarantee the usability of valve, guaranteed the sustainable operation of equipment pipeline, reach sealability stable, solved in the past common valve, perishable, poor sealing performance, the difficult problem that working life is short.
