Description
Technical field
The present invention relates to technical field of water heaters, in particular to the magnesium of a kind of heat-exchanging water tank
The plugging device of rod installing hole.
Background technology
Water heater has heat-exchanging water tank, can install magnesium rod in heat-exchanging water tank, and the effect of magnesium rod is:
In water, discharge magnesium ion generate magnesium oxide molecule with water oxygen ions binding, at this moment in water tank
Water is exactly that other accessory of water tank would not be corroded by anaerobic water, plays the work of protection water tank
With.But, magnesium rod is relatively valuable, not every heat-exchanging water tank all be not added with distinguish install magnesium additional
Rod, but need to consider water quality, therefore, what application was most at present is to arrange on heat-exchanging water tank
Reserved magnesium rod installing hole.
Magnesium rod is usually mounted to the upper end face of heat-exchanging water tank.Before dispatching from the factory or need not install magnesium additional
The occasion of rod, is essentially all employing one bolt for the closure of above-mentioned preformed hole and adds a sealing gasket
Seal.But, due to the general ovalize of shape of magnesium rod installing hole, therefore, no matter
Use the bolt with which kind of shape bolt head, even if sealing gasket deforms because of pretightning force,
It also is difficult to ensure the sealing of magnesium rod installing hole.
Summary of the invention
Technical problem solved by the invention: the closure of the magnesium rod installing hole of heat-exchanging water tank, due to
The general ovalize of shape of magnesium rod installing hole, therefore, it is close that prior art uses a bolt to add one
The sealing means of packing is it is difficult to ensure that the sealing of magnesium rod installing hole.
The present invention provides following technical scheme: the closure of the magnesium rod installing hole of a kind of heat-exchanging water tank fills
Put, including sealing ring, sealing member, screw element, described sealing ring ovalize, described sealing
Part includes base, some pieces of tensioning blocks, described base ovalize, and described base centre is opened
If screwed hole, described tensioning block is positioned at the top of base, and the medial surface of described tensioning block surrounds one
Conical bore, described conical bore is connected with screwed hole, and it is oval that the lateral surface of described tensioning block surrounds one
Face, described ring set is on the lateral surface of tensioning block and base, and described screw element includes setting
There are externally threaded screw rod, the circular conic protruding portions being arranged on screw rod, described circular conic protruding portions
It is positioned at above external screw thread；
Described tensioning block offers extruding groove；The more convenient tensioning block of offering of extruding groove expands to the periphery
?；
The external diameter of the ellipsoid that the external diameter of described base is surrounded more than the lateral surface of tensioning block.As
This design, sealing ring coordinates for closely cooperating with base, to prevent the water in heat-exchanging water tank from leading to
Cross the gap between sealing ring and chassis outer side wall to exosmosis.
By technique scheme, ring set is on sealing member, and sealing ring and sealing member block again
In magnesium rod installing hole.Afterwards, the screw rod of screw element is screwed at spiral shell by the engagement of internal and external threads
In pit, during screwing, the circular conic protruding portions on screw rod gradually snaps in tensioning block
In the conical bore that side is surrounded, and extruding tensioning block medial surface, tensioning block is outside after being squeezed
Enclosing prominent, tensioning block outside tight seal circle again, so, sealing ring is interior with magnesium rod installing hole
Sidewall is in close contact, i.e. the plugging device closure that magnesium rod installing hole is described by the present invention.This
Bright by screw element squeeze sealing member, make sealing member expand to the periphery, tight seal circle, and then
Make sealing ring closely cooperate with magnesium rod installing hole, reach to block the purpose of magnesium rod installing hole.
Further illustrating as the present invention, the quantity of described tensioning block is four.Certainly, open
The quantity of tight block is the most, and the effect of tensioning is the best, but in view of manufacturing cost, herein tensioning
The quantity of block is preferably four.
As a further improvement on the present invention, the lateral surface of described tensioning block is provided with prominent ring, institute
Stating sealing ring lateral surface and be provided with protuberance, described protuberance is fitted on prominent ring.Tensioning block
The protuberance of sealing ring is limited on the outer surface of heat-exchanging water tank by prominent ring, i.e. sealing ring
Protuberance has position-limiting action for sealing ring, and the prominent ring of tensioning block is to whole plugging device
For, there is position-limiting action.

Detailed description of the invention
As it is shown in figure 1, the plugging device of the magnesium rod installing hole of a kind of heat-exchanging water tank, including sealing
Circle 10, sealing member 20, screw element 30.
As shown in Figure 6, described sealing ring 10 ovalize, described sealing ring 10 lateral surface sets
There is protuberance 101.
As shown in figs. 2 to 4, described sealing member 20 includes 21, four pieces of tensioning blocks 22 of base.
Described base 21 ovalize, described base 21 centre offers screwed hole 210.Described
Tight block 22 is positioned at the top of base 21, and the medial surface of described tensioning block 22 surrounds a conical bore
220, described conical bore 220 is connected with screwed hole 210, and the lateral surface of described tensioning block 22 encloses
An ellipsoid, described tensioning block 22 is become to offer extruding groove 221.The outside of described tensioning block 22
Face is provided with prominent ring 222.
As it is shown in figure 5, described screw element 30 includes being provided with externally threaded screw rod 31, being arranged on
Circular conic protruding portions 32 on screw rod 31, described circular conic protruding portions 32 is positioned on external screw thread
Side.
As shown in Figure 4, the external diameter of described base 21 is surrounded more than the lateral surface of tensioning block 22
The external diameter of ellipsoid.
In practical operation, sealing ring 10 is sleeved on the lateral surface of tensioning block 22 and base 21,
Sealing ring 10 closely cooperates with the lateral surface of base 21, and the protuberance 101 of sealing ring 10 pastes
It is combined on the prominent ring 222 of sealing member 22.Sealing ring 10 and sealing member 20 are stuck in magnesium rod again
In installing hole, wherein, the heat exchange of the protuberance 101 of sealing ring 10 and magnesium rod installing hole periphery
The outer surface contact of water tank.Afterwards, the external screw thread of screw element 30 is wound around raw material band, screw rod
31 screw in screwed hole 210 by the engagement of internal and external threads, during screwing, and spiral shell
Circular conic protruding portions 32 on bar 31 gradually snaps in the circular cone that tensioning block 22 medial surface is surrounded
In hole 220, and extruding tensioning block 22 medial surface, tensioning block 22 highlights after being squeezed to the periphery,
Tensioning block 22 outside tight seal circle 10 again, so, sealing ring 10 and magnesium rod installing hole
Medial wall is in close contact, i.e. the plugging device closure that magnesium rod installing hole is described by the present invention.
Above content is only the better embodiment of the present invention, for the ordinary skill people of this area
