Abstract
The utility model relates to a novel valve cover, comprising a fixing disc at the upper end and a guide cylinder at the lower end. The guide cylinder is inserted into a valve body and reversely conical. And the external diameter of the top end of the guide cylinder is the same as the internal diameter of the valve body. A round baffle is arranged at the lower end of the guide cylinder. A sealing ring is fixed at the upper end of the baffle. The external diameter of the sealing ring is the same as the internal diameter of the valve body. As the guide cylinder at the lower end is in a reversely conical design, and the baffle and the sealing ring are arranged at the lower end of the guide cylinder, the novel valve cover disclosed by the utility model can effectively avoid the abrasion between the valve cover and the valve body and further enhances the sealing property of a valve. Furthermore, the novel valve cover has the advantages of simple structure, low manufacture cost and convenience for maintenance.
Description
Technical field
The utility model relates to a kind of lid, and especially a kind of valve gap that is fixedly mounted on valve tip belongs to the valving technical field.
Background technique
Valve generally is made up of valve body, valve rod and valve gap, and valve gap is a T shape tubular, and insert in the valve body lower end of valve gap.In present valve industry, valve gap and valve body junction plane place are easy to leak, and in order to guarantee the sealing effect of valve, it is identical with the internal diameter of valve body that the external diameter of valve gap lower end all is designed to, and the fit tolerance of the two is very little.But, when as installed, can compare difficulty, and the outside of valve gap lower end is close to the valve body inboard, both damaged valve body and valve gap easily, also bring very big inconvenience to maintenance.In addition, for fear of valve gap and valve body junction plane place seepage, a lot of businessmans add a lot of fixed blocks or undulatory block all with the junction plane place of valve gap and valve body, and its structure is complicacy very, both waste material and cost, and its sealing effect is also not obvious.
The model utility content
The utility model purpose is to provide a kind of simple in structure, easy to maintenance for the deficiency that overcomes existing technology, avoids the wearing and tearing between valve gap and valve body, the novel valve gap of good sealing effect.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of novel valve gap comprises upper end fixed tray and lower end guide cylinder; Said guide cylinder inserts in the valve body; Said guide cylinder is an inverted cone, and the external diameter on guide cylinder top is identical with the internal diameter of valve body; The lower end of said guide cylinder is provided with circular baffle plate; Said baffle plate upper end is fixed with seal ring; The external diameter of said seal ring is identical with the internal diameter of valve body.
Preferably, the distance of said baffle plate and guide cylinder bottom surface is 10mm.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of novel valve gap of the utility model scheme, the inverted cone design of its lower end guide cylinder and the baffle plate and the seal ring of guide cylinder lower end; When effectively avoiding wearing and tearing between valve gap and valve body, also strengthened the sealing of valve, and it is simple in structure; Low cost of manufacture, easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the stereogram of the novel valve gap of the utility model;
Accompanying drawing 2 is the axial sectional view of the novel valve gap of the utility model;
Wherein: 1, fixed tray; 2, guide cylinder; 3, baffle plate; 4, seal ring.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of novel valve gap of the utility model scheme, the inverted cone design of its lower end guide cylinder and the baffle plate and the seal ring of guide cylinder lower end; When effectively avoiding wearing and tearing between valve gap and valve body, also strengthened the sealing of valve, and it is simple in structure; Low cost of manufacture, easy to maintenance.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
