Abstract
The utility model relates to an end cap seal structure, including upper end cover and bottom end cover, all be provided with endocentric threaded attachment hole on upper end cover and bottom end cover, be provided with outside bellied trapezoidal tenon spare A, trapezoidal tenon spare B on the lower terminal surface of upper end cover, up end and trapezoidal tenon spare A, the trapezoidal tenon spare B of bottom end cover correspond position punishment and have do not offered trapezoidal recess A, trapezoidal recess B, and trapezoidal tenon spare A installs in trapezoidal recess A, trapezoidal tenon spare B installs in trapezoidal recess B, is provided with trapezoidal gasket A in trapezoidal recess A be provided with trapezoidal gasket B in the trapezoidal recess B. Through adopting trapezoidal seal structure, trapezoidal tenon spare and the cooperation of trapezoidal groove phase to install trapezoidal gasket in trapezoidal recess, because sealed face is narrower, it is little to compress tightly the area, and because of receiving stopping of recess, the seal face can not extruded to the gasket, and it is reliable to improve its sealing performance.
Description
Technical field
The utility model relates to technical field of sealing technology, particularly relates to a kind of end cover sealing structure, for improving sealability.
Background technique
Sealing is anti-fluid or solid particle from revealing between adjacent junction plane and preventing introduced contaminants as the component of the intrusion such as dust and moisture machinery equipment inside or measure.The leakage of equipment is very important quality problems, leakage of oil, leak, the normal operation of the equipment that has a strong impact on that leaks gas, outward appearance, working efficiency and working life, and can environmental pollution be caused, waste energy.Cause the reason of leakage to mainly contain two aspects: one is the result due to machining, the surface of engineering goods certainly exists various defect and shape and size deviation, therefore, inevitably produces gap in mechanical parts connection place; Two is that sealing both sides exist pressure difference, and working medium will be revealed by gap.Sealing can be divided into the large class of the motive sealing two between the static seal between geo-stationary junction plane and relative movement junction plane.Static seal mainly contains dot encapsulation, and glue sealing seals three major types with contacting.According to working pressure, static seal is by being divided into mesolow static seal and high pressure static seal.It is softer that material commonly used by mesolow static seal, the pad sealing that pad is wider, and high pressure static seal is then comparatively hard with material, the metallic shim that contact width is very narrow.Motive sealing can be divided into rotary seal and reciprocation sealing two kinds of fundamental types.Whether contact with the component of its effect relative movement by Sealing, contact seal and noncontact seal can be divided into.In general, the good airproof performance of contact seal, but limit by fretting wear, be applicable to the occasion that sealing surface linear velocity is lower.The sealing of noncontact seal is poor, is applicable to the occasion of fair speed.
Current upper end cap and the sealing contact surface of lower end cap amass comparatively large, and the impacting force provided is less, is easy to be extruded seal face, causes leakage.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of end cover sealing structure, improves its sealability, prevents from revealing.
The utility model is achieved through the following technical solutions:
A kind of end cover sealing structure, comprise upper end cap and lower end cap, described upper end cap and lower end cap are provided with concentric threaded mounting hole, in described threaded mounting hole, bolt is installed, described bolt is used for upper end cap and lower end cap to be installed together, the lower end surface of described upper end cap is provided with the trapezoidal tenon part A of outwardly convex, trapezoidal tenon part B, the upper-end surface of described lower end cap and trapezoidal tenon part A, trapezoidal tenon part B corresponding position offers trapezoidal groove A respectively, trapezoidal groove B, described trapezoidal tenon part A is arranged in trapezoidal groove A, described trapezoidal tenon part B is arranged in trapezoidal groove B, trapezoidal pad A is provided with in described trapezoidal groove A, trapezoidal pad B is provided with in described trapezoidal groove B.
As optimal technical scheme of the present utility model, exterior edge face and the trapezoidal groove A inwall of described trapezoidal pad A are fitted.
As optimal technical scheme of the present utility model, the described exterior edge face of trapezoidal pad B and the inwall of trapezoidal groove B are fitted.
As optimal technical scheme of the present utility model, described trapezoidal pad A and trapezoidal pad B all adopts polyurethane material to make.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by adopting trapezoidal sealing configuration, trapezoidal tenon part matches with trapezoidal groove, and trapezoidal pad is installed in trapezoidal groove, because sealing surface is narrower, compress area little, and because being subject to the stop of groove, pad can not extrude seal face, can improve its sealability reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Described a kind of end cover sealing structure, as shown in Figure 1, comprise upper end cap 1 and lower end cap 2, described upper end cap 1 and lower end cap 2 are provided with concentric threaded mounting hole 3, in described threaded mounting hole 3, bolt 7 is installed, described bolt 7 is for being installed together upper end cap 1 and lower end cap 2, the lower end surface of described upper end cap 1 is provided with the trapezoidal tenon part A4 of outwardly convex, trapezoidal tenon part B8, the upper-end surface of described lower end cap 2 and trapezoidal tenon part A4, trapezoidal tenon part B8 corresponding position offers trapezoidal groove A5 respectively, trapezoidal groove B9, described trapezoidal tenon part A4 is arranged in trapezoidal groove A5, described trapezoidal tenon part B8 is arranged in trapezoidal groove B9, trapezoidal pad A10 is provided with in described trapezoidal groove A5, trapezoidal pad B6 is provided with in described trapezoidal groove B9.
The described exterior edge face of trapezoidal pad A10 and the inwall of trapezoidal groove A5 are fitted, and the described exterior edge face of trapezoidal pad B6 and the inwall of trapezoidal groove B9 are fitted, and preferably, described trapezoidal pad A10 and trapezoidal pad B6 all adopts polyurethane material to make.
The present embodiment is by adopting trapezoidal sealing configuration, and trapezoidal tenon part matches with trapezoidal groove, and in trapezoidal groove, be provided with trapezoidal pad, because sealing surface is narrower, compress area little, and because being subject to the stop of groove, pad can not extrude seal face, can improve its sealability reliable.The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
