Abstract
The invention relates to a composite floating ball. The floating ball comprises an inner ball and an outer ball, wherein the outer ball is coated outside the inner wall and is made of an organic material; and the inner ball is a hollow ball and is made of a nonmetal or metal material. The floating ball is formed by coating the inner wall through injection molding, mold pressing and extrusion, and the inner ball comprises one layer or multiple layers. The inner wall is a hollow ball made of a high-temperature and high-pressure resisting high-density nonmetal or metal material, so that condensation caused by temperature change is not easy to occur in the inner wall under the environment with high temperature and great temperature change. In order to meet the designed technological requirements of the outer ball, the outer ball is made of an organic material through the technologies of injection molding, mold pressing, extrusion and the like. The defects of various traditional floating balls are overcome. The composite floating ball has the advantages of reasonable, safe and reliable technologies, wide application range and long service life, and is especially applicable to important parts of an automatic water stopping device for the breakage of all-glass evacuated solar collector tubes.
Description
Technical field
The present invention relates to a kind of duct element, particularly relate to a kind of combined type ball float.
Background technology
Country actively promotes green energy resource now, as the critical piece complete glass vacuum sun thermal-collecting tube in the domestic solar water heater, ball float can play great role as one of them vitals at high temperature or the big medium-term and long-term operate as normal of environment of difference variation to solar collector pipe.
At present, the general ball float that uses in market has following several, metal hollow ball plastic hollow ball, and glass hollow balls etc. all are the ball floats made from single material.Can there be following problem in above-mentioned ball float in actual use;
As easily producing condensation in the ball float in the big environment of high temperature or difference variation, thereby in long-term the use, can produce the buoyancy deficiency that condensed water causes ball in because of the effect spheroid of condensation, can not use for a long time, and the life-span shortly directly influences designing requirement.
Because the material difference is in order to reach designing requirement, the loaded down with trivial details manufacturing cost height of processing hollow ball complex process can only can not be extensive use of in small lot batch manufacture.
Summary of the invention
The object of the invention provides the combined type ball float that a kind of performance well is not subjected to extraneous thermal effect, described ball float divides endosphere and ectosphere, and described ectosphere is wrapped in outside the endosphere, and described ectosphere is that organic material is made, described endosphere is a hollow sphere, and described endosphere is nonmetal or metal material is made.
Advantage of the present invention is: adopt high temperature resistant, high pressure resistant and highdensity high performance material is as hollow ball, make this product under the very big environment of difference variation, be difficult for producing condensation and cracky not in the ball, thereby guarantee long-time the use, technology is reasonable, safe and reliable, of many uses, long service life, is particularly suitable for the vitals of the damaged automatic water stopping device of complete glass vacuum sun thermal-collecting tube.
As the described ball float of a kind of improvement of the present invention by injection moulding, mold pressing and be squeezed in endosphere and wrap up outward, this manufacturing process is made easy, is easy to large-scale production.
Be made up of one or more layers as the described endosphere of another kind of improvement of the present invention, its endosphere can be made up of multilayer, to improve its performance.
Description of drawings
Fig. 1 is a cutaway view of the present invention
1, ectosphere; 2, endosphere;
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
Provide a kind of a kind of embodiment of having of combined type ball float as Fig. 1 the object of the invention, its ball float divides endosphere 2 and ectosphere 1.
Its endosphere 2 is high temperature resistant, high pressure resistant for adopting, and highdensity nonmetal or hollow ball that metal material is made can float in liquid.
Its ectosphere 1 is for through injection moulding, and mold pressing and extrusion process injection organic material outer wrapping and can be floated in liquid on endosphere 2 and compound making guaranteed the face shaping and the quality of spheroid.
Its advantage is, adopt high temperature resistant, high pressure resistant and highdensity high performance material is as hollow ball, make this product under the very big environment of difference variation, be difficult for producing condensation and cracky not in the ball, thereby guarantee long-time the use, technology is reasonable, safe and reliable, of many uses, long service life, is particularly suitable for the vitals of the damaged automatic water stopping device of complete glass vacuum sun thermal-collecting tube.
Described ball float is by injection moulding, mold pressing and be squeezed in endosphere 2 outer parcels, and this manufacturing process is made easy, is easy to large-scale production.
Described high performance material is nonmetal or metal material, this consideration mainly be the high temperature resistant of material, high pressure resistant and density, therefore no matter all materials that meets this are nonmetal or metal material can use.
Endosphere of the present invention also can be made up of multilayer, to improve the ball float performance.
