Description

The solar water heater pipe joint

The utility model relates to the joint that connects between a kind of collector, does not have rigid connection especially therebetween, and pipe joint slidably.

Pipe joint is usually used in connection between the collector, and the rigid scyewed joint of normal employing between pipe joint and the collector, long-term assembling practice is told us, especially as the connection between a plurality of heat collectors of solar water heater, to the process deviation in assembly process, adaptability is very poor, can bring difficulty to assembling work.When daily maintenance and repair need the disassembling, assembling and replacing heat collector, because the problem on connecting must be aided with its heat collector that closes on of dismounting for heat collector of dismounting, if we are designed to not have rigid connection therebetween with the pipe joint that connects between collector, and can on collector, slide, can guarantee the sealing that connects again, this will improve the efficient of assembling and working service repairing greatly, thereby has improved labour productivity and the cost that has reduced commodity.

The purpose of this utility model is to provide a kind of engineering that is easy to assemble and the dismounting maintenance and repair according to above-mentioned, can better adapt to the assembly technology deviation that connects between collector, does not have rigid connection therebetween, can effectively seal, can be along the pipe joint of collector slip.

The purpose of this utility model is achieved through the following technical solutions:

A kind of solar water heater pipe joint, by pipe junctor (1), locknut (2), seal ring (3) is formed, wherein manage junctor (1) and can be socketed on the coupled collector (4), and can slide along collector (4), locknut (2) is built-in with seal ring (3), locknut (2) is spirally connected with pipe junctor (1), and forces seal ring (3) sealing by the chamfering (12) of pipe junctor (1).

The utlity model has following advantage and effect:

1, the utility model can be used for the connection of the collector between a plurality of heat collectors of solar water heater, pipe joint can slide on collector, and can effectively ensure sealing, this structural type better adapts to the deviation of assembly technology at vertical and horizontal, very convenient during dismounting, owing to used the utility model, the disassemble and assemble work of heat collector is become simply, the technical requirements when satisfying assembling easily.

2, the utility model is simple in structure, rationally, is easy to make, and is with low cost.

The drawing of accompanying drawing is described as follows:

Fig. 1 is that the utility model connects the situation schematic representation with the collector of heat collector

Fig. 2 A is the front view of the utility model pipe junctor

Fig. 2 B is the side view of the utility model pipe junctor

Fig. 3 A is the front view of the utility model locknut

Fig. 3 B is the side view of the utility model locknut

Among the figure: 1-manages junctor, the 11-hexagon, and the 12-chamfering, the 13-body, the 2-locknut, the 21-ring recess,

The 3-seal ring, 4-collector, 5-heat collector

Be described further below in conjunction with drawings and Examples:

As shown in Figure 1, the utility model is by managing junctor 1, locknut 2, seal ring 3 compositions, wherein, pipe junctor 1 can be socketed on the coupled collector 4, and can slide along collector 4, locknut 2 is built-in with seal ring 3, and locknut 2 is spirally connected with pipe junctor 1, and forces seal ring 3 sealings by the chamfering 12 of pipe junctor 1.

As seen from the figure, the utility model and commonly used pipe joint difference are no rigid connection the between pipe joint and collector, can between two coupled collectors 4, slide, it is vertical that this has just solved rigid connection, and the horizontal difficulty that causes of assembling deviation is when the installation of a plurality of heat collectors 5 or dismounting, can be under motionless situation of facing heat collector 5 mutually, only need loosening dismounting to intend changing the two ends of heat collector 5, and make the outside slippage of pipe joint, just can finish the work of dismounting and change.When connecting work, collector 4 sleeves can be gone into manage junctor 1, tighten locknut 2 then, when the seal ring 3 in placing locknut 2 touches the chamfering 12 of pipe junctor 1, the chamfering inclined-plane is to the promotion of collector 4 surface direction and compress the surface that seal ring 3 closely is fitted in collector 4, thereby reaches the purpose of sealing.

By Fig. 2 A, Fig. 2 B as seen, pipe junctor 1 is by hexagon 11, chamfering 12, body 13 is formed, and cooperates with spanner when wherein hexagon 11 is used to assemble and installs, the size of chamfering 12 should be complementary with the seal ring 3 of different model size and material, the chamfering 12 of present embodiment is (2 * 45 °), and seal ring is the O type, and material is a silicone rubber.

Body 13 inside are the clear opening in order to grafting collector 4, the screw thread of outside system to be spirally connected with locknut 2.

By Fig. 3 A, Fig. 3 B as seen, locknut 2 is a hexagon, its inside is shaped on and manages screw thread 22 that junctor 1 connects and the through hole 21 of pegging graft with collector 4.

The utility model is owing to the use that matches with the collector 4 of different size model, and size of the present utility model for this reason also can be formed series.
