Description
Technical field
The utility model relates to technical field of water heaters, in particular to a kind of blocking device of magnesium rod mounting hole of heat exchange water tank.
Background technique
Water heater has heat exchange water tank; in heat exchange water tank, magnesium rod can be installed; the effect of magnesium rod is: in water, discharge magnesium ion and water oxygen ions binding generates magnesium oxide molecule, and the water at this moment in water tank is exactly that anaerobic water would not corrode other accessory of water tank, plays the effect of protection water tank.But magnesium rod is more valuable, what not every heat exchange water tank did not add differentiation installs magnesium rod additional, but needs to consider water quality, and therefore, what application was maximum at present is on heat exchange water tank, arrange reserved magnesium rod mounting hole.
Magnesium rod is installed on the upper end face of heat exchange water tank usually.Before dispatching from the factory or do not need the occasion installing magnesium rod additional, the shutoff for above-mentioned preformed hole is all that employing one bolt adds a sealing gasket and seals substantially.But, due to the general ovalize of shape of magnesium rod mounting hole, therefore, no matter adopt the bolt with which kind of shape bolt head, even if sealing gasket deforms because of pretightening force, be also difficult to the sealing ensureing magnesium rod mounting hole.
Model utility content
The technical problem that the utility model solves: the shutoff of the magnesium rod mounting hole of heat exchange water tank, due to the general ovalize of shape of magnesium rod mounting hole, therefore, the sealing means that prior art adopts a bolt to add a sealing gasket is difficult to the sealing ensureing magnesium rod mounting hole.
The utility model provides following technological scheme: a kind of blocking device of magnesium rod mounting hole of heat exchange water tank, comprise seal ring, Sealing, threaded piece, described seal ring ovalize, described Sealing comprises base, some pieces of tensioning blocks, described base ovalize, described base centre offers tapped hole, described tensioning block is positioned at the top of base, the inner side surface of described tensioning block surrounds a conical bore, described conical bore is connected with tapped hole, the outer side surface of described tensioning block surrounds an ellipsoid, described ring set is on the outer side surface of tensioning block and base, described threaded piece comprises and is provided with externally threaded screw rod, be arranged on the circular conic protruding portions on screw rod, described circular conic protruding portions is positioned at above outside thread.
By technique scheme, ring set is on Sealing, and seal ring and Sealing are stuck in magnesium rod mounting hole again.Afterwards, the screw rod of threaded piece screws in tapped hole by the engagement of internal and external threads, in the process screwed, the circular conic protruding portions on screw rod snaps in the conical bore that tensioning block inner side surface surrounds gradually, and extrudes tensioning block inner side surface, give prominence to the periphery after tensioning block is squeezed, tensioning block is outside tight seal circle again, so, and the madial wall close contact of seal ring and magnesium rod mounting hole, that is, magnesium rod mounting hole is by blocking device shutoff described in the utility model.The utility model, by threaded piece squeeze sealing member, makes Sealing expand to the periphery, tight seal circle, and then seal ring and magnesium rod mounting hole are closely cooperated, and reaches the object of shutoff magnesium rod mounting hole.
As further improvement of the utility model, described tensioning block offers squeezing groove.The more convenient tensioning block of offering of squeezing groove is expanded to the periphery.
Further illustrate as of the present utility model, the external diameter of the ellipsoid that the outer side surface that the external diameter of described base is greater than tensioning block surrounds.Design like this, seal ring coordinates for closely cooperating with base, to prevent water in heat exchange water tank by the gap between seal ring and chassis outer side wall to exosmosis.
Further illustrate as of the present utility model, the quantity of described tensioning block is four.Certainly, the quantity of tensioning block is more, and the effect of tensioning is better, but considers manufacture cost, and the quantity of tensioning block is preferably four herein.
As further improvement of the utility model, the outer side surface of described tensioning block is provided with outstanding ring, and described seal ring outer side surface is provided with protuberance, and described protuberance is fitted on outstanding ring.The protuberance of seal ring is limited on the outer surface of heat exchange water tank by the outstanding ring of tensioning block, that is, the protuberance of seal ring has position-limiting action to seal ring, and the outstanding ring of tensioning block, for whole blocking device, has position-limiting action.
