Abstract
A connection structure at the tail end of a copper coil in a water tank is characterized in that the connection structure includes a joint fixed at the tail end of the copper coil, a limit bulge is arranged outside the joint, a thread casing is welded on the outer wall of an inner container of the water tank, one end of the joint is placed in the thread casing, and an outer sleeving fixation nut is used for sealing and fixedly connecting the joint and the thread casing. The connection structure at the tail end of a copper coil in a water tank has a reasonable structure design, is convenient to mount, and has a good sealing effect; fewer connection components are adopted, the connection is firm, and the connection of the copper coil and the sealing of the water tank inner container at the outlet of the copper coil can be effectively realized; and the connection structure is convenient and fast to mount and dismount, and is low in maintenance cost and long in service life.
Description
Technical field
The utility model belongs to the assembly structure of heat storage water tank, the syndeton of the outlet of the concrete bronze pan tube that relates to a kind of water tank with interior bronze pan tube.
Background technology
In the prior art, the heat exchange type heat storage water tank generally is employed in the heat-exchanger rig of bronze pan tube as heat transferring medium is set in the inner water tank.The bronze pan tube outlet is set on the outer wall of inner water tank, and the end of bronze pan tube is connected with the external heat-exchanging pipeline through joint again.Because bronze pan tube when extending to the outside in the inner water tank, need be considered the sealing of bronze pan tube outlet and inner water tank wall, also to consider the sealing of bronze pan tube connection external lug simultaneously, therefore, its intractability is bigger.Adopt the material of filling or be bonded and sealed between the exit of bronze pan tube and bronze pan tube realized sealing more in the prior art, and such sealing effectiveness is relatively poor, and under the bigger condition of the temperature of water tank and bronze pan tube variations in temperature, the problem revealed very easily appears in this junction.
The utility model content
The utility model provides a kind of reasonable in design, the terminal syndeton of the interior bronze pan tube of water tank easy for installation, that sealing effectiveness is good; Its coupling assembling that adopts is less; Be connected firmly, can realize the connection of bronze pan tube and the sealing of bronze pan tube exit and inner water tank effectively, and installation and removal be convenient and swift; Maintenance cost is low, long service life.
The technical scheme that the utility model adopted is following:
The terminal syndeton of bronze pan tube in a kind of water tank; It is characterized in that said syndeton comprises that one is fixed on the terminal joint of bronze pan tube; This joint is outside equipped with positive stop lug boss; The welding of inner water tank outer wall is provided with a threaded sleeve, and an end of said joint is positioned at this threaded sleeve, and an overcoat hold-down nut is with being sealedly and fixedly connected between said joint and threaded sleeve.
In one embodiment, the fixing said joint of the terminal welding of said bronze pan tube, an end suit of this joint is weldingly fixed on the terminal outer wall of bronze pan tube.
In one embodiment, bronze pan tube outlet is set on the said inner water tank outer wall, the end of bronze pan tube is exported by this bronze pan tube and draws the fixing said joint of back welding, the said threaded sleeve of welding on the inner water tank outer wall of this bronze pan tube outlet periphery.
In one embodiment, said overcoat hold-down nut is provided with internal thread, and the one of which end is provided with a spacing interior protuberance, is equipped with between the positive stop lug boss of protuberance and said joint in this is spacing.
In another embodiment, a side of the end of said threaded sleeve and the positive stop lug boss of said joint face conflict ringwise is provided with, and is provided with an annular gasket between this side of the end of this threaded sleeve and the positive stop lug boss of said joint.
The terminal syndeton of bronze pan tube adopts welding and thread connecting mode in this water tank, and the metal connected mode that it is commonly used based on this and effect is preferable has realized being connected and sealing of bronze pan tube, inner water tank through adopting joint, threaded sleeve and overcoat hold-down nut.The end of bronze pan tube can be realized the connection of external heat-exchanging medium pipeline through joint, and this joint can adopt copper joint, can realize the firm welding of bronze pan tube and this joint effectively.One end of the threaded sleeve that is provided with on the inner water tank outer wall and this inner water tank outer wall weld setting, and after welding, this threaded sleeve can carry out the thread set of other assembly through its screw thread, the bronze pan tube outlet on the closed tank inner bladder outer wall.When the internal thread of overcoat hold-down nut carries out suit at the external screw thread with threaded sleeve; Protuberance pushes the positive stop lug boss that is provided with on the joint in inboard be provided with spacing of overcoat hold-down nut to the port of threaded sleeve; Between the end port that makes threaded sleeve and said positive stop lug boss ringwise the face sealing contact; Promptly realize the fixing of bronze pan tube joint, realized the sealing of inner water tank outer wall again.In order further to improve sealing effectiveness, an annular gasket can be set on said ring surface.
The beneficial effect of the utility model is; The terminal syndeton reasonable in design of bronze pan tube in this water tank, easy for installation, sealing effectiveness is good, its coupling assembling that adopts is less, is connected firmly; Can realize the connection of bronze pan tube and the sealing of bronze pan tube exit inner water tank effectively; And installation and removal are convenient and swift, and maintenance cost is low, long service life.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to set forth.
