Abstract
The utility model provides a vacuum tube anti-leakage joint of a solar water heater, which is installed on the top end of a main tube and in a water storage tank. The joint is welded with the main tube in multipoint. The main tube is cylindrical. Water inlet openings are distributed fully at the edge of a top circulating fixed plate. A rubber stepping bar is fixed at the periphery of the water inlet opening. The center of the circulating fixed plate is fixed with a round-flat rubber movable lug, the outer diameter of which is equal to that of the circulating fixed plate. The main tube is communicated with a glass vacuum tube so as to effectively prevent the water leakage caused by the crack of the vacuum tube. The joint has simple structure, low cost and convenient installation and is based on the easy alteration of the existing solar water heater.
Description
Technical field:
The utility model belongs to mechanical engineering, relates to a kind of solar water heater parts, especially a kind of joint of solar water heater vacuum-tube.
Background technology:
At present, along with industrial expansion, glass vacuum tube solar energy can heat collector become a new way utilizing solar energy, have of many uses, the thermal efficiency is high, advantage such as pollution-free, but glass-vacuum tube is for a long time under the insolation of the sun, very easily produce and break, make a large amount of water from the vacuum tube that breaks, flow out, and general solar water heater is installed on roof, damaged difficult the discovery, cause a large amount of water wastes, going back the good scheme of neither one now can address this problem.
Summary of the invention:
The purpose of this utility model is to avoid above-mentioned deficiency and a kind of joint of leaking behind the glass evacuated tracheal rupture of can effectively preventing of providing.
The purpose of this utility model is achieved in that
The solar water heater vacuum-tube Matheson and Dresser joint, Matheson and Dresser joint is installed on main body pipe top, cistern interior, joint and main body pipe are that multiple spot is welded to connect, the main body pipe is cylindrical, the circulation fixed head edge on top is covered with the inlet opening, the inlet opening periphery is fixed with the rubber filler strip, and circulation fixed head central authorities are fixed with disc rubber movable lug by fixed screw, and the external diameter of rubber movable lug is identical with the external diameter of circulation fixed head; The main body pipe communicates with glass-vacuum tube; Main body pipe and Matheson and Dresser joint and water storage box are that strictness is tightly connected; Hot bar of rubber and rubber movable lug can be other macromolecular material.
Compared with prior art the utility model has the advantages that: can effectively prevent to leak behind the glass evacuated tracheal rupture, simple in structure, cost is low, and is easy for installation, and it is easy etc. to transform on prior solar water heater.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a circulation fixed head vertical view of the present utility model.
1 is the inlet opening among the figure, and 2 is fixed screw, and 3 are the circulation fixed head, and 4 is the rubber movable lug, and 5 is the rubber filler strip, and 6 is sealing rubber ring, and 7 is water storage box, and 8 is glass-vacuum tube, and 9 is solder joint.
The specific embodiment:
Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2: the solar water heater vacuum-tube Matheson and Dresser joint, Matheson and Dresser joint is installed on main body pipe top, water storage box 7 inside, joint is that multiple spot welding 9 is connected with the main body pipe, the main body pipe is cylindrical, circulation fixed head 3 edges on top are covered with inlet opening 1, and inlet opening 1 periphery is fixed with rubber filler strip 5.Circulation fixed head 3 central authorities are fixed with disc rubber movable lug 4 by fixed screw 2, and the external diameter of rubber movable lug 4 is identical with the external diameter of circulation fixed head 3; The main body pipe communicates with glass-vacuum tube 8; Main body pipe and Matheson and Dresser joint and water storage box 7 are tightly connected by sealing rubber ring 6 strictnesses; Rubber filler strip 5 and rubber movable lug 4 can be other macromolecular material.
In the use, the water in the water storage box 7 enters main body pipe and glass-vacuum tube 8 by inlet opening 1, and after glass-vacuum tube 8 damaged, current will speed up, 4 downward and rubber sheet gasket 5 applyings of rubber movable lug, and joint cuts out.
