Abstract
The invention discloses a device for blocking an elliptical mounting hole of a heat exchange water tank. The device comprises a screw (10), a nut (20), an upper sealing member (30) and a lower sealing member (40), wherein the nut is screwed on the screw; the upper sealing member is arranged on the screw in a sleeving manner; the nut is positioned above the upper sealing member; the lower sealing member is provided with a boss and an edge; a top surface of the boss is fixedly arranged at one end of the screw; the shape and the size of an outer contour of the boss are the same as those of the elliptical mounting hole of the heat exchange water tank; the edge is provided with an annular groove; a seal ring is arranged in the groove. The lower sealing member is arranged in the heat exchange water tank; the upper sealing member is arranged on the outer side of the heat exchange water tank; pressure is applied to the upper sealing member by the nut; the lower sealing member is stretched by the screw; the seal ring on the lower sealing member is in close contact with the inner wall of the heat exchange water tank; the purpose of blocking the elliptical mounting hole is achieved.
Description
Technical field
The present invention relates to technical field of water heaters, the device of oval installing hole on a kind of shutoff heat-exchanging water tank, especially magnesium rod installing hole on shutoff heat-exchanging water tank.
Background technology
Install the effect that magnesium rod can play protection water tank in heat-exchanging water tank, reason is that magnesium rod discharges magnesium ion in water and water oxygen ions binding generates magnesia molecule, and the water at this moment in water tank is exactly that anaerobic water would not corrode other accessory of water tank.
Because magnesium rod is more valuable, what not every heat-exchanging water tank did not add differentiation installs magnesium rod additional, and therefore, production company often arranges reserved magnesium rod installing hole on heat-exchanging water tank.
Magnesium rod is installed on the upper end face of heat-exchanging water tank usually, therefore magnesium rod installing hole is generally located at the upper end face of heat-exchanging water tank, and the general ovalize of shape of magnesium rod installing hole.Before dispatching from the factory or do not need the occasion installing magnesium rod additional, how effective shutoff is carried out to magnesium rod installing hole, become a technical problem being worth probing into.
Summary of the invention
Technical problem solved by the invention: the oval magnesium rod installing hole how on heat exchanging water tank carries out effective shutoff.
The invention provides following technical scheme: the device of the oval installing hole of a kind of shutoff heat-exchanging water tank, comprises screw rod, nut, upper seal, lower seal.Described nut screws on screw rod, described upper sealing member sheathing is on screw rod, described nut is positioned at the top of seal, described lower seal is provided with boss, edge, described boss end face is fixed on one end of screw rod, the outer contour shape size of described boss is identical with the shape size of the oval installing hole of heat-exchanging water tank, and described edge annular groove, installs sealing ring in described groove.
By technique scheme, lower seal stretches in heat-exchanging water tank by oval installing hole, and the boss of lower seal embeds in oval installing hole, the sealing ring on the edge of lower seal and heat-exchanging water tank contact internal walls.Upper seal is in the outside of heat-exchanging water tank, the wall contacts of upper seal and heat-exchanging water tank, nut applies pressure to upper seal, screw rod stretching lower seal, the inwall close contact of the sealing ring in lower seal and heat-exchanging water tank, reaches the object of the oval installing hole of shutoff.
Further illustrate as of the present invention, described upper seal is identical with the shape of lower seal boss, and described upper seal hollow, described lower seal boss can stretch into the hollow space of seal.The degree of depth of described upper seal hollow space should be greater than the height that oval installing hole given prominence to by lower seal boss, and so, tightening nut, screw rod could stretching lower seal, and then makes the inwall close contact of sealing ring in lower seal and heat-exchanging water tank.
As a further improvement on the present invention, annular groove is offered in the bottom surface of described upper seal, installs sealing ring in described groove.Improvement like this has four technique effects: the first, and the wall of some heat-exchanging water tanks is thinner, and upper seal and lower seal are installed hole wall by the ellipse that sealing ring acts on heat-exchanging water tank in opposite directions and can be prevented from ovally installing hole wall deformation; The second, the elasticity of sealing ring can prevent whole plugging device from loosening; 3rd, the elasticity of sealing ring can increase the contact tightness degree of lower seal and heat-exchanging water tank inwall; 4th, the upper seal having installed sealing ring can effectively prevent extraneous impurity from entering slotted eye or being trapped in bore edges.

Detailed description of the invention
As shown in Figure 1, the device of the oval installing hole of a kind of shutoff heat-exchanging water tank, comprises screw rod 10, nut 20, upper seal 30, lower seal 40.
Described nut 20 screws on screw rod 10.
Described upper seal 30 is sleeved on screw rod 10, described upper seal 30 hollow.As shown in Figure 2, annular groove 300 is offered in the bottom surface of described upper seal 30, installs sealing ring in described groove 300.Described nut 20 is positioned at the top of seal 30.
Described lower seal 40 is provided with boss 41, edge 42, described boss 41 end face is fixed on one end of screw rod 10, the outer contour shape size of described boss 41 is identical with the shape size of the oval installing hole of heat-exchanging water tank, annular groove 420 is offered at described edge 42, installs sealing ring in described groove 420.
Described upper seal 30 is identical with the shape of lower seal boss 41, and described lower seal boss 41 can stretch into the hollow space of seal 30.
During actual installation, installation personnel holds screw rod 10, and lower seal 40 is stretched into oval installing hole obliquely, and after lower seal 40 enters heat-exchanging water tank, installation personnel adjusts and the lower seal 40 that stretches, and lower seal boss 41 is embedded in oval installing hole.Afterwards, upper seal 30 is sleeved on screw rod 10 by installation personnel, again nut 20 is screwed on screw rod 10, the upper bottom of seal 30 and the exterior surface of heat-exchanging water tank, meanwhile, the hollow space that oval installing hole is partially submerged into seal 30 given prominence to by lower seal boss 41, installation personnel fastening nut 20, so, plugging device of the present invention and the shutoff oval installing hole of heat-exchanging water tank.
Above content is only better embodiment of the present invention, and for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, this description should not be construed as limitation of the present invention.
