Abstract
The utility model discloses a kind of seal nipples, it is desirable to provide a kind of simple in structure, good airproof performance, seal nipple easy for installation, production cost is low.The utility model is sleeved on the copper pipe of heat exchanger, it includes linkage section and limiting section, and external screw thread is provided on the outer surface of the connecting pin, and the inside of the limiting section offers seal groove, and the seal groove is internally provided with sealing ring.The utility model is applied to the technical field of Types of Heat Transmitter in Wall Mounted Boilers pipe joint.
Description
Technical field
The utility model is related to the technical field of Types of Heat Transmitter in Wall Mounted Boilers pipe joint, more particularly to a kind of seal nipple.
Background technology
Wall-hung boiler is a kind of water heater using natural gas as the energy, and there is anti-frost protection, anti-dry protection, accident extinguishing to protect
A variety of safety precautions such as the excessively high protection of shield, temperature, the anti-jamming protection of water pump.There is wall-hung boiler powerful Domestic central to heat
Function, so being widely used.
And the heating function of wall-hung boiler, typically to be realized by heat exchanger, heat exchanger is connected with exterior line,
Hot water is supplied to interior, so as to heat for interior.And heat exchanger is typically to be connect by connector with exterior line, it is existing
In technology, after the copper pipe of heat exchanger is arranged connector, it is also necessary to flange is carried out with the copper pipe of dedicated process equipment heat exchanging device,
Increase production cost；And when carrying out connector connection, connector is in active state, and installing plate butt joint does not limit work
With inconvenience when attaching nut is installed.Meanwhile the leakproofness of existing connector is poor, is susceptible to drainage.
Utility model content
Technical problem to be solved in the utility model be overcome the deficiencies of the prior art and provide it is a kind of it is simple in structure,
Good airproof performance, seal nipple easy for installation, production cost is low.
Technical solution is used by the utility model：The utility model is sleeved on the copper pipe of heat exchanger, it includes connecting
Section and limiting section are connect, external screw thread is provided on the outer surface of the connecting pin, the inside of the limiting section offers seal groove, institute
It states seal groove and is internally provided with sealing ring.
Further, the connecting pin of the seal nipple is connect across installing plate with outer pipeline, and the limiting section includes rotation
Turn limiting section and axial limiting section, the rotary stopper section are adapted with the mounting hole opened up on the installing plate.
Further, the rotary stopper section is adapted with the mounting hole opened up on the installing plate.
Further, the area of the outer fringe surface of the axial limiting section is more than the area of the mounting hole.
Further, the seal nipple is fabricated by copper material.
The beneficial effects of the utility model are：Since the utility model is sleeved on the copper pipe of heat exchanger, it includes connection
Section and limiting section are provided with external screw thread on the outer surface of the connecting pin, and the inside of the limiting section offers seal groove, described
Seal groove is internally provided with sealing ring, so, the seal nipple of the utility model passes through the external screw thread that is set on the linkage section
It is connect with the nut on exterior line, so as to which the copper pipe of heat exchanger be connected with exterior line, when mounted, the limiting
Section can play position-limiting action to seal nipple, facilitate installation；The sealing ring is set in the inside of the limiting section, is improved
The leakproofness of connector；Meanwhile pipeline connection is carried out by seal nipple, do not need to copper pipe using special equipment heat exchanging device into
Row flange, reduces production cost.
Description of the drawings
Fig. 1 is the scheme of installation of the utility model；
Fig. 2 is the schematic front view of the utility model.
Specific embodiment
As depicted in figs. 1 and 2, in the present embodiment, the utility model is sleeved on the copper pipe 2 of heat exchanger, the sealing
Connector 1 includes linkage section 3 and limiting section 4, and external screw thread 5 is provided on the outer surface of the linkage section 3, described to limit the interior of section 4
Portion offers seal groove 6, and the seal groove 6 is internally provided with sealing ring 7, and the seal nipple 1 on the linkage section 3 by setting
The external screw thread 5 put is connect with the nut on exterior line, so as to which the copper pipe 2 of heat exchanger be connected with exterior line, is being pacified
During dress, the limiting section 4 can play position-limiting action to the seal nipple 1, facilitate installation；In the inside of the limiting section 4
The sealing ring 7 is set, improves the leakproofness of the seal nipple 1；Meanwhile by the seal nipple 1 of the utility model into
Row pipeline connects, and does not need to carry out flange using the copper pipe 2 of special equipment heat exchanging device, reduces production cost.
In the present embodiment, the linkage section 3 of the seal nipple 1 is connect across installing plate with outer pipeline, the limiting section 4
Including rotary stopper section 4 and axial limiting section 4, the rotary stopper section 4 is adapted with the mounting hole opened up on the installing plate.
The rotary stopper section 4 is matched with the mounting hole, the rotation of the seal nipple 1 when can prevent from installing, so as to convenient
The seal nipple 1 coordinates the installation of the nut on exterior line；The axial limiting section 4 can limit the seal nipple 1
Axial movement, prevent the seal nipple 1 entirely pass through the mounting hole.
In the present embodiment, the rotary stopper section 4 is adapted with the mounting hole opened up on the installing plate, to described close
Sealing joint 1 plays position-limiting action.
In the present embodiment, the area of the outer fringe surface of the axial limiting section 4 is more than the area of the mounting hole.
In the present embodiment, the seal nipple 1 is fabricated by copper material, because seal nipple 1 is directly contacted with water, is adopted
1 corrosion of seal nipple can be prevented with copper material, increases the service life of the seal nipple 1.
The utility model is applied to the technical field of Types of Heat Transmitter in Wall Mounted Boilers pipe joint.
Although the embodiment of the utility model is described with practical solution, do not form the utility model is contained
The limitation of justice, for those skilled in the art, according to group of this specification to the modification of its embodiment and with other schemes
Conjunction will be apparent from.
