Abstract
The utility model relates to a sealing rubber ring. The sealing rubber ring is suitable for the seal between the glass vacuum solar energy heat collecting tube of a glass vacuum solar energy heat (boiling) water device and a water tank (or a connecting and collecting tube). The sealing rubber ring is a T-shaped sealing rubber ring, and the inner wall of the sealing rubber ring is provided with more than two semi-O-shaped rings which are inwards convex. The sealing rubber ring has the advantages of good sealing performance and very convenient installation.
Description
The utility model relates to a kind of novel seal rubber ring, is specially adapted to the water tank (or connecting pipe) of glass vacuum tube solar (opening) hydrophone and the sealing between the glass vacuum heat collection tube of solar energy.
The sealing of glass vacuum tube solar (opening) hydrophone is one of key technology that influences its quality, therefore, is paid close attention to by those skilled in the art always.At present, the sealing between glass vacuum heat collection tube of solar energy and the water tank (or connecting pipe) is finished by a cone seal rubber ring.The structure of cone seal rubber ring as shown in Figure 1, the outer rim of cone rubber circle 1-1 has an annular groove 1-2, a V-shaped groove 1-3 is arranged at the top.The schematic cross-section of cone seal rubber ring as shown in Figure 2,2-1 is the cone rubber circle, 2-2 is an annular groove, 2-3 is a V-shaped groove.The cone seal rubber ring is installed on the hole, garden of water tank (or connecting pipe), block the edge in water tank (or connecting pipe) hole, garden by the groove of cone seal rubber ring, glass vacuum heat collection tube of solar energy inserts water tank (or connecting pipe) by the cone seal rubber ring, forms sealing configuration.Accompanying drawing 3 is sealing configuration schematic cross-sections, 3-1 is water tank (or connecting pipe), 3-2 is the garden bore edges of water tank (or connecting pipe), 3-3 is the cone seal rubber ring, 3-4 is a glass vacuum heat collection tube of solar energy, and A is the direction that glass vacuum heat collection tube of solar energy inserts water tank (or connecting pipe).Be not difficult to find out by accompanying drawing 3:,, meet easily cracking of heat, poor sealing performance because the V-shaped groove inner edge is thinner though 1. glass vacuum heat collection tube of solar energy combines for the conical surface with the cone seal rubber ring; Glass vacuum heat collection tube of solar energy must with water tank (or connecting pipe) hole, garden drive fit, sealability just can be got well, but, because the hole, garden is to make with punching technology, the garden bore edges is equally sharp like sharp sword, when glass vacuum heat collection tube of solar energy when the A direction is inserted, because of squeezing action is very easily cut brokenly cone seal rubber ring annular groove, broken ring sealing causes and leaks; 3. adding shell at water tank (or connecting pipe), and between the two in the cast behind the thermal insulating material, the groove of cone seal rubber ring is stuck on the bore edges of water tank (or connecting pipe) garden, is very difficult.
The purpose of this utility model is the deficiency at prior art, designs a kind of novel seal rubber ring, cooperates with the garden hole flanging of water tank (or connecting pipe), improves sealability, is convenient to install.
The utility model is a T shape sealing rubber ring, and its inwall has half inwardly outstanding more than 2 "O.Its cross section as shown in Figure 4,4-1 is a T shape rubber ring, 4-2 is half "O.
Below in conjunction with accompanying drawing the utility model is described in detail, accompanying drawing 5 is that the utility model is formed the sealing configuration schematic cross-section, 5-1 is a T shape sealing rubber ring, 5-2 is water tank (or connecting pipe), 5-3 is the garden hole flanging of water tank (or connecting pipe), 5-4 is a glass vacuum heat collection tube of solar energy, and B is the direction that glass vacuum heat collection tube of solar energy inserts water tank (or connecting pipe).By last figure as seen, between T shape sealing rubber ring 5-1 and water tank (or connecting pipe) the garden hole flanging 5-3 is cone match, when glass heat-collecting vacuum tube 5-4 when the B direction is inserted water tank (or connecting pipe) 5-2, squeezing action only can make and seal between T shape sealing rubber ring 5-1 and the garden hole flanging 5-3 better, can not cut brokenly rubber ring, simultaneously squeezing action also can make the top half "O to turning up, make seal between T shape sealing rubber ring 5-1 and the garden hole flanging 5-3 more reliable; Because 3 half "Os on the squeezing action T shape sealing rubber ring inwall form the sealing of triple " O " shape to glass vacuum heat collection tube of solar energy, favorable sealing property, T shape sealing rubber ring is put into water tank (or connecting pipe) garden hole flanging and is got final product, and installs very convenient.
Major advantage of the present utility model is: 1. good seal performance; 2. easy for installation.
