Description

A kind of connecting pipe structure on pressure-bearing inner liner
Technical field
The utility model belongs to technical field of solar water heaters, the connecting pipe structure being related on a kind of pressure-bearing inner liner.
Background technology
Existing solar water heater is all that pressure-bearing inner liner is built-in in attemperater, first will be in pressure-bearing in assembly Courage both ends are fixed on the both ends of attemperater.There are two need to stretch out the water inlet pipe of attemperater and go out for connection in the middle part of pressure-bearing inner liner Water pipe, this two more difficult installations of water pipe, and need to ensure the leakproofness with pressure-bearing inner liner, so generally using welding side Formula.But if being installed into attemperater after being first welded again, cause the length of inlet and outlet pipes that must be shorter than pressure-bearing inner liner in this way With the gap of attemperater, not so can block.And if by the way of first installing and welding afterwards, welding is thus substantially increased Difficulty, and can not ensure the leakproofness between inlet and outlet pipes and attemperater.
Utility model content
The purpose of this utility model is the presence of the above problem in view of the prior art, it is proposed that the company on a kind of pressure-bearing inner liner Joint pipe structure, easy for installation, good airproof performance.
The purpose of this utility model can be realized by following technical proposal:A kind of connecting pipe structure on pressure-bearing inner liner, It is characterised in that it includes the connection pipe body of the tube head and inlay card that are welded on pressure-bearing inner liner wall on water tank wall, the tube head tool There is internal thread, external groove is provided on the connecting end surface of tube head, the connecting pin of the connection pipe body is with matched outer with internal thread Screw thread has step in the outer bottom of thread, inner groovy is provided on step, O-ring seal, the connecting pin of tube head are equipped in inner groovy Portion can lean with the step of connection pipe body.
Further, the side wall of the external groove is inclined-plane, and the gradient on inclined-plane is 45 °.
Further, tube head is identical as the outer diameter of connection pipe body.
Further, the side wall of the inner groovy is inclined-plane, and the gradient on inclined-plane is 45 °.
Further, the water tank is provided with the through-hole stretched into for connection pipe body, and through hole inlay card has section in concave character type Ring type seal.
First by tube head and pressure-bearing inner liner firm welding, then pressure-bearing inner liner is installed into attemperater.After installing, by through-hole It is coaxial with tube head to just, making through-hole with tube head, then connection pipe body is extend into through-hole, be rotatablely connected tube body, make external screw thread with Screw-internal thread fit, until step and the tube head end of connection pipe body are completely against installing.
Compared with prior art, the connecting pipe structure on this pressure-bearing inner liner has the following advantages:
1. it is easy for installation, tube head is first welded, then the mode being connected through a screw thread tightens connection pipe body,
2. good airproof performance has O-ring seal between tube head and connection pipe body, sealing effect, connection pipe body and guarantor are improved It is equipped with ring type seal between warm water tank wall, improves the sealing effect of the two.

Fig. 1 is the schematic diagram of the connecting pipe structure on this pressure-bearing inner liner.
In figure, 1, tube head;2, connection pipe body;3, pressure-bearing inner liner;4, attemperater;5, internal thread;6, external groove;7, outer spiral shell Line;8, step;9, inner groovy;10, O-ring seal;11, through-hole;12, ring type seal.
Specific implementation mode
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these examples.
As shown in Figure 1, the connecting pipe structure on this pressure-bearing inner liner, including the tube head 1 and card that are welded on 3 wall of pressure-bearing inner liner Connection pipe body 2 on water tank wall, the tube head 1 have internal thread 5, external groove 6, institute are provided on the connecting end surface of tube head 1 State connection pipe body 2 connecting pin have with 5 matched external screw thread 7 of internal thread, there is step 8 in 7 bottom of external screw thread, on step 8 It is provided with inner groovy 9, is equipped with O-ring seal 10 in inner groovy 9, the connection end of tube head 1 can offset with the step 8 of connection pipe body 2 It leans on.
The side wall of the external groove 6 is inclined-plane, and the gradient on inclined-plane is 45 °, and tube head 1 is identical as the outer diameter of connection pipe body 2.
The side wall of the inner groovy 9 is inclined-plane, and the gradient on inclined-plane is 45 °, and the water tank is provided with to be stretched into for connection pipe body 2 Through-hole 11, it is in the ring type seal 12 of concave character type that inlay card, which has section, at through-hole 11.
First by tube head 1 and 3 firm welding of pressure-bearing inner liner, then pressure-bearing inner liner 3 is installed into attemperater 4.It, will after installing Through-hole 11 is extend into just, making through-hole 11 and tube head 1 coaxial, then by connection pipe body 2 in through-hole 11 with tube head 1, rotation connection pipe Body 2 makes external screw thread 7 and internal thread 5 coordinate, until step 8 and 1 end of tube head of connection pipe body 2 are completely against installing.
Connecting pipe structure on this pressure-bearing inner liner, easy for installation, good airproof performance.
