Description

Technical Field

[0001] The utility model belongs to the technical field of solar flat collector production, and relates to a Y-shaped flat collector sealing ring. Background Art

[0002] Flat collectors have now become the dominant products in the solar energy market and are widely used in fields such as domestic water heating, industrial water heating, and building heating. Most of the flat collectors used in the current market are of the tube-sheet structure, and the metal tubes serving as flow channels are sealed and installed with the flat collector frame in the form of round holes + round sealing rings.

[0003] However, the defect of the above installation method is that the sealing ring is first manually installed on the installation holes on the profile frame, and then the metal tube is inserted through one end of the sealing ring. Since the metal tube and the sealing ring are in interference fit, the frictional resistance between the sealing ring and the metal tube is large, and the insertion process of the metal tube requires manual operation, which is difficult to install and very inconvenient. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a Y-shaped flat collector sealing ring, which first assembles the lower seal, the metal tube, and finally assembles the upper seal, with simple and convenient installation and improved installation efficiency.

[0005] The utility model is realized by the following technical solutions:

[0006] A Y-shaped flat collector sealing ring includes a lower seal and an upper seal. The lower seal is semi-circular, and a first semi-circular hole is provided on the straight edge of the lower seal, and a first groove is machined on the outer arc edge of the lower seal;

[0007] The upper seal is square, a second semi-circular hole is provided at the bottom edge of the upper seal, and second grooves are provided on the top edge and the left and right side edges of the upper seal;

[0008] A connecting plate is provided on the outer surface of the top of the upper seal, and a horizontally distributed support plate is provided on the inner side of the connecting plate. The top edge of the connecting plate is higher than the top surface of the support plate.

[0009] Further, a baffle extending downward is provided at the inner end of the support plate.

[0010] Further, a square positioning block is provided at the bottom of the inner side surface of the lower seal.

[0011] Further, the upper seal, the connecting plate, the support plate, and the baffle are made of nylon material, and the lower seal is made of silicone material.

[0012] Further, the connecting plate is an isosceles trapezoid.

[0013] The beneficial effects achieved by the present utility model compared with the prior art are as follows:

[0014] 1. First, install the lower seal through the first groove in the mounting hole of the frame of the flat plate collector, then pass one end of the metal pipe through the mounting hole, make the metal pipe cooperate with the first semi-circular hole, install the upper seal through the second groove, the second semi-circular hole cooperates with the metal pipe, and the upper seal and the lower seal form a seal for the metal pipe up and down. Make the support plate fit on the support surface of the frame of the flat plate collector. When installing the glass, the support plate transfers force to the upper seal through the connecting plate, so that the first semi-circular hole, the second semi-circular hole and the metal pipe are in interference fit;

[0015] The present utility model changes the previous way of inserting the sealing ring into the metal pipe, which saves time and effort, is simple and convenient to install, and improves the installation efficiency;

[0016] 2. A square positioning block is provided at the bottom of the inner side surface of the lower seal. When installing the lower seal, the square positioning block abuts against the bottom of the frame of the flat plate collector to prevent the lower seal from being misaligned during installation;

[0017] 3. The inner end of the support plate is provided with a baffle extending downward, which effectively prevents the upper seal and the connecting plate from being misaligned during the installation process and improves the installation accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0024] As Figures 1-3 shown, this embodiment discloses a Y-shaped flat plate collector sealing ring, which includes a lower seal 3 and an upper seal 9. The lower seal 3 is made of silicone material into a semicircle. A first semi-circular hole 5 is machined on the straight edge of the lower seal 3, and a first groove 6 is machined on the outer arc edge of the lower seal 3 for mating with the mounting hole on the flat plate collector frame 1. For positioning, a square positioning block 7 is machined at the bottom of the inner side surface of the lower seal 3. In this embodiment, the lower seal 3 and the square positioning block 7 are integrally made of silicone material.

[0025] The upper seal 9 is square. A second semi-circular hole 8 is machined on the bottom edge of the upper seal 9. When the upper seal 9 and the lower seal 3 are assembled up and down, a circular hole is formed. Second grooves are machined on the top edge and the left and right side edges of the upper seal 9. An isosceles trapezoidal connecting plate 2 is provided on the outer surface of the top of the upper seal 9. A horizontally distributed support plate 10 is provided inside the connecting plate 2. The top edge of the connecting plate 2 is higher than the top surface of the support plate 10. A baffle 11 extending downward is provided at the inner end of the support plate 10. The upper seal 9, the connecting plate 2, the support plate 10 and the baffle are integrally made of nylon material. As is well known, although nylon material also has elasticity, it is relatively harder than silicone material itself.

[0026] The specific installation process of the Y-shaped flat plate collector sealing ring of the present utility model is as follows:

[0027] As Figure 4As shown in the figure, for the frame 1 of the flat-plate collector in the prior art, a bottom edge 12 of the frame is provided on the inner side of the bottom, and a support surface 14 is provided on the inner side of the top. The support surface 14 is used to carry and install the glass. Before installing the sealing ring described in this embodiment, mounting holes are drilled on the frame surface 13 of the flat-plate collector frame 1, and the shape of the mounting holes is an arched door structure. First, the lower seal 3 is installed through the first groove 6 in the frame mounting hole. When installing the lower seal 3, the square positioning block 7 is located inside the flat-plate collector frame 1 and abuts against the bottom edge of the frame to prevent the lower seal 3 from rotating axially and being misaligned during installation. Then, one end of the metal tube 4 is passed through the mounting hole, so that the metal tube 4 is matched with the first semi-circular hole 5, and the upper seal 9 is installed through the second groove. The second semi-circular hole 8 is matched with the metal tube 4, and the upper seal 9 and the lower seal 3 form a seal for the metal tube 4 up and down. The support plate 10 is fitted on the support surface of the flat-plate collector frame 1, and the baffle 11 blocks the inner end of the support surface. When installing the glass cover plate, the glass cover plate presses the support plate 10 downward, and the support plate 10 transmits force to the upper seal 9 through the connecting plate 2, so that the first semi-circular hole 5, the second semi-circular hole 8 and the metal tube 4 are in interference fit; this changes the previous way of inserting the sealing ring into the metal tube 4, saving time and effort, being simple and convenient to install, and improving the installation efficiency.
