Abstract
A water heater magnesium stick sealing structure comprises a magnesium stick, a magnesium stick fixing holder, a ring-shaped sealing component and a water heater shell, wherein the lower end of the magnesium stick is fixed in the magnesium stick fixing holder, the lower surface of the magnesium stick fixing holder is fixedly provided with a bolt, a screw hole is arranged on the water heater shell, the bolt is matched with the screw hole on the water heater shell, the ring-shaped sealing component sleeved on the bolt is arranged between the magnesium stick fixing holder and the water heater shell, a limiting device is arranged on the outer edge of the lower surface of the magnesium stick fixing holder, and the ring-shaped sealing component is limited in a space composed of the lower surface of the magnesium stick fixing holder, the bolt the water heater shell and the limiting device. The water heater magnesium stick sealing structure has the following beneficial effects that the water heater magnesium stick fixing holder with the sealing structure is provided with sealing limitation, can control the shape change of the sealing component, namely, the compression amount of the sealing component, effectively prevents water leakage, and improves the service life of the sealing component.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, especially relates to a kind of water heater magnesium rod hermetically-sealed construction.
Background technology
Existing water heater magnesium rod hermetically-sealed construction referring to shown in Figure 1, comprises magnesium rod 1, magnesium rod holder 2, lip ring 3 and water heater housing 4; Described magnesium rod 1 lower end is fixed in the magnesium rod holder 2, the lower surface of this magnesium rod holder 2 is installed with bolt 21, screw 41 couplings on this bolt 21 and the water heater housing 4, be provided with the lip ring 3 that is enclosed within on the bolt 21 between described magnesium rod holder 2 and the water heater housing 4, both sealing part 3 was limited between magnesium rod holder 2, water heater housing 4 and the bolt 21.Because infinite place device between the bolt 21 of water heater magnesium rod holder 2 and the water heater housing 4 makes that seal 3 decrements are uncontrollable, causes and presses change excessive to seal 3, reduces seal life or seal is directly extruded, and causes and leaks.
The utility model content
The technical problems to be solved in the utility model provides a kind of water heater magnesium rod hermetically-sealed construction; This structure is provided with sealing on water heater magnesium rod holder spacing, and sealing is spacing can effectively be controlled seal, the service life that can effectively prevent to leak and can improve seal.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: it comprises magnesium rod, magnesium rod holder, lip ring and water heater housing; Described magnesium rod lower end is fixed in the magnesium rod holder, be installed with bolt on the lower surface of this magnesium rod holder, the water heater housing is provided with screw, and the screw coupling on described bolt and the water heater housing is provided with the lip ring that is enclosed within on the bolt between described magnesium rod holder and the water heater housing; The outer edge place of described magnesium rod holder lower surface is provided with stopping means, and described lip ring is limited in the space of magnesium rod holder lower surface, bolt, water heater housing and stopping means formation.
The utlity model has following beneficial effect: it is spacing that the water heater magnesium of the utility model hermetically-sealed construction rod holder is provided with sealing, and the change of shape of seal both seal decrement is controlled, and effectively prevented to leak, and improved the service life of seal.
