Abstract
The utility model discloses a joint structure for a water inlet and a water outlet. The joint structure comprises a water inlet, a water outlet and a threaded movable joint, wherein the threaded movable joint consists of a nut, a flat joint and a sealing washer; the water inlet and the water outlet are provided with external threads which are matched with the nut of the threaded movable joint. Quick connection and disassembly of the water inlet as well as the water outlet and the threaded movable joint are realized through screw-in and screw-out of the nut and the external threads, and meanwhile, the sealing property is guaranteed. Compared with the conventional metal pipe joint which requires winding of a raw tape and realizes disassembly and assembly through a wrench, the joint structure has the advantage of high convenience and speed. Meanwhile, the plastic product is low in price and reduced in cost.
Description
Technical field
The present invention relates to the joint structure of a kind of water intake and water outlet.
Background technique
On general water treatment apparatus, all be provided with at least two water pipes of water inlet and outlet, former water flows into water treatment apparatus inside from water intake, from water outlet, flows out after a series of processing.
Water intake need to be connected with outer water tube with water outlet, and existing water intake and water outlet joint structure are to utilize metallic pipe coupling to realize this function.Water intake and water outlet are provided with the screw thread be complementary with metallic pipe coupling, when being linked and packed, at first need on turnover water pipe, be wound around appropriate unsintered tape, be used to strengthening the seal between pipeline, then use spanner that pipe joint is connected with water outlet with water intake.Existing joint structure exists installs loaded down with trivial details defect, and the metallic pipe coupling price is higher.
Summary of the invention
The technical problem solved: for the deficiencies in the prior art, the invention provides a kind of water intake and water outlet joint structure, solve existing joint structure loaded down with trivial details defect is installed.
Technological scheme: for solving the problems of the technologies described above, the following technological scheme of the present invention:
A kind of water intake and water outlet joint structure, comprise water intake, water outlet and threaded for union, and described threaded for union comprises nut, plain adapter and seal washer; Described nut is tubulose, and the circumferential surface of described nut intracavity one end is provided with screw thread, and the outside thread that on described water intake and water outlet, the nut of setting and threaded for union is complementary, the other end circumferential surface of described nut intracavity are provided with the interior step of a circle projection; Described plain adapter is tubulose, and described plain adapter outer peripheral surface one end is provided with the outer step of a circle; Interior step Spielpassung in described plain adapter external diameter and nut, the external diameter of the upper outside step of described plain adapter is between the intracavity diameter and interior stepped diameters of described nut; Described seal washer is placed on the end face of outer step one end of plain adapter.
Further, in the present invention, the internal diameter of described intake pipe and outlet pipe is less than the external diameter of described seal washer.Guarantee that sealing is reliable.
Further, in the present invention, the nut of described threaded for union and the material of plain adapter are the PVC plastics.PVC plastic movable joint strength meets the demands, and low price.
Beneficial effect: the present invention is by arranging and realize that with the outside thread that the threaded for union nut is complementary water intake is connected and dismounting with the quick of threaded for union with water outlet on the water intake at water treatment apparatus and water outlet.Compare metallic pipe coupling in the past, during connection, only need rotating nut gently, to continuing rotation, seal washer is in plain adapter and turnover water pipe end face joint naturally by the outside thread interlock on nut and water intake and water outlet, realize joint and seal, without being wound around in addition unsintered tape; During dismounting, counterrotating nut, i.e. quick release gently.Plastic whorl union moderate strength, low price, reduce costs.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of water intake and water outlet joint structure, comprise water intake 1, water outlet 2 and threaded for union 3.Described threaded for union 3 comprises nut 4, plain adapter 5 and seal washer 6; Described nut 4 is tubulose, and the circumferential surface of described nut 4 inner chamber one ends is provided with screw thread, the outside thread that on described water intake 1 and water outlet 2, the nut 4 of setting and threaded for union 3 is complementary; The other end circumferential surface of described nut 4 inner chambers is provided with the interior step 7 of a circle projection; Described plain adapter 5 is tubulose, and described plain adapter 5 outer peripheral surface one ends are provided with the outer step 8 of a circle; Interior step Spielpassung in described plain adapter 5 external diameters and nut 4, the external diameter of the upper outside step 8 of described plain adapter 5 is between the intracavity diameter and interior step 7 diameters of described nut 4; Described seal washer 6 is placed on the end face of outer step one end of plain adapter 5.The internal diameter of described water intake 1 and water outlet 2 is less than the external diameter of described seal washer.
Described nut 4 can move on plain adapter 5, while being linked and packed, by the nut of threaded for union 34 with water intake 1 and water outlet 2, aim at respectively, the nut of threaded for union 34 is screwed on the outside thread on water intake 1 and water outlet 2, until nut 4 can't continue rotation, the seal washer 5 of plain adapter 5 ends is positioned in the middle of the end face of the end face of plain adapter 5 and water intake 1, water outlet 2 just, and the internal diameter of described water intake 1 and water outlet 2 is less than the external diameter of described seal washer 6, guarantee like this sealing effectively.While needing dismounting, counterrotating nut 4, can unload threaded for union 23 fast.
The nut 4 of described threaded for union 3 and the material of plain adapter 5 are the PVC plastics.Than metallic pipe coupling in the past, PVC plastic movable joint strength meets the demands, and low price.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
