Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of flat plate solar collector connection components, and in particular to a sealing gasket with a high temperature resistant built-in positioning ring for solar collectors. Background Technology
[0002] In existing technologies, the connection between the flat-plate solar collector and the flexible metal hose requires flanges A and B in conjunction with metal gaskets to achieve a sealed connection. The metal gaskets used in existing technologies are ordinary gaskets without a positioning structure, which presents the following problems during installation:
[0003] The inability to accurately position the metal gasket makes it easy for the gasket to be damaged during tightening due to eccentricity, thus losing its sealing function. Long-term use can easily lead to leakage, and even economic losses due to antifreeze leakage.
[0004] The sealing gasket is a disposable consumable. If the installation fails due to eccentricity, a new gasket needs to be replaced and reconnected, which increases the material cost.
[0005] The installation requires two skilled workers to work together (one to position the clamps and the other to install them). This not only demands high skill levels from the workers but also results in a high failure rate and low installation efficiency.
[0006] Therefore, there is an urgent need for a sealing gasket that can achieve precise positioning, improve installation efficiency, and enhance sealing reliability, in order to overcome the shortcomings of existing technologies. Utility Model Content
[0007] The purpose of this invention is to provide a high-temperature resistant gasket with an internal positioning ring for solar collectors. By adding an internal positioning ring, the gasket is precisely positioned relative to the flange, thereby improving the sealing effect and installation efficiency.
[0008] To achieve the above objectives, this utility model provides a high-temperature resistant gasket with an internal positioning ring for a solar collector, comprising a gasket body and an inner positioning ring; the inner positioning ring is fixedly disposed on one side of the gasket body and arranged coaxially with the gasket body; the inner positioning ring is used to cooperate with the flange B connecting pipe of the solar collector for positioning, so that the gasket body is coaxial with the flange A and flange B of the solar collector; both the gasket body and the inner positioning ring are made of high-temperature resistant material and are adapted to the KF flange interface connection of the solar collector.
[0009] Preferably, the inner positioning ring and the sealing gasket body are integrally formed.
[0010] Preferably, the outer diameter of the inner positioning ring and the inner diameter of the flange B connecting pipe are in a small clearance fit.
[0011] Preferably, the high-temperature resistant material is a metallic material that can withstand the temperature of the solar collector's operating environment.
[0012] Preferably, the axial length of the inner positioning ring is not greater than the axial length of the flange B connecting pipe.
[0013] Preferably, the cross-section of the sealing gasket body is circular and is adapted to the sealing surfaces of flange A and flange B.
[0014] Preferably, the inner positioning ring is made of the same material as the sealing gasket body.
[0015] Therefore, the sealing gasket with a high-temperature resistant built-in positioning ring for a solar collector, as described above, has the following technical advantages:
[0016] (1) By cooperating with the inner positioning ring and the flange B connecting pipe, this utility model can ensure that the metal sealing gasket body is strictly coaxial with flange A and flange B, thus avoiding sealing failure due to eccentricity.
[0017] (2) This utility model improves sealing reliability through structural improvement, eliminates leakage risks during long-term use, and reduces economic losses caused by antifreeze leakage;
[0018] (3) This utility model greatly improves installation efficiency. No skilled workers are required. A single ordinary worker can complete the installation in one go on the first operation, and the installation efficiency is increased by more than 80%.
[0019] (4) This utility model avoids damage to the sealing gasket caused by positioning deviation, reduces the wear and replacement cost of the sealing gasket, and reduces material waste.
[0020] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0030] Unless otherwise defined, the technical or scientific terms used in this utility model shall have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0031] like Figures 1 to 3 As shown, a high-temperature resistant gasket with an inner positioning ring for a solar collector includes a gasket body 1 and an inner positioning ring 2; the inner positioning ring 2 is integrally formed on one side of the gasket body 1, and the two are coaxially arranged.
[0032] Both the sealing gasket body 1 and the inner positioning ring 2 are made of high-temperature resistant metal materials, which can adapt to the temperature requirements of the working environment of the flat plate collector and are compatible with the size specifications of the KF flange interface.
[0033] The outer diameter of the inner positioning ring 2 is fitted with the inner diameter of the flange B connecting pipe 4 with a small clearance. The axial length of the inner positioning ring 2 is 1 / 2 to 2 / 3 of the axial length of the flange B connecting pipe 4, which ensures positioning stability while avoiding interference with the flange fit.
[0034] Working principle:
[0035] like Figure 4As shown, the sealing gasket body 11 with inner positioning ring 2 is placed into the lower connecting parts, namely flange B3 and flange B connecting pipe 4, so that the inner positioning ring 2 is inserted into flange B connecting pipe 4 to achieve initial positioning.
[0036] like Figure 5 As shown, align the upper connecting part, namely flange A5, with the lower connecting part. At this time, the sealing gasket body 1 is located between flange A5 and flange B3, and is kept coaxial by the positioning action of the inner positioning ring 2.
[0037] like Figure 6 As shown, flange A5 and flange B3 are fastened with clamp 6, and the sealing gasket body 1 is pressed by the flange face to achieve a reliable seal at the connection surface.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
