Abstract
The utility model relates to a combined movable joint. Except for that the utility model is composed of a combined A end 1, a combined B end 2, a crimpling nut 3, a sealing washer 4, the utility model is characterized in that the end parts of the combined A end 1 and the combined B end 2 are respectively cast with an outer thread joint 5, and the utility model has a thread coupling function. The utility model has the advantages of simple fabrication technology, low cost, easy installation, material saving and labor saving, and the utility model reduces air leakage and water leakage phenomena and is especially suitable for being used for radiator installation works.
Description
The utility model relates to a kind of union, particularly a kind of combined live joint that has the silk function.
At present, the connection part at the union two ends of domestic use all is an internal thread, because the difficult processing of internal thread, thereby processing technology is cumbersome, and the cost height more has when being connected with other pipe fitting, two ends must be equipped with and can connect silk, because various pipe fittings all are independently, so joint is many, easily cause gas leakage, water leakage phenomenon.
The purpose of this utility model will provide the simple cost of a kind of processing low, easy for installation exactly, and can reduce the combined live joint of gas leakage, water leakage phenomenon
The purpose of this utility model be achieved in that a kind of combined live joint by combination first end 1, combination second end 2, tighten female 3, seal washer 4 and form, it is characterized in that described combination first end 1, make up second end 2 outer end connection parts nipple 5 is arranged.
The utility model nipple 5 is made up of cast steel material, and it is cast in combination first end 1, combination second end 2.This union also can at one end be processed with outer silk, is processed with internal thread at the other end.
The utility model compared with prior art has following some advantage:
1, owing to nipple 5 is arranged in combination first end 1, combination second end 2 outer ends, but and once-through, technology is simple, cost is low, and is easy for installation, the material-saving saving of labor.
2, because nipple 5 has been arranged, when being connected with other pipe fitting, saved two ends to silk, reduced connection procedure, thereby reduced the phenomenon of leaking, can more easily guarantee installation quality.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of the utility model Fig. 1.
Combination first end, 2. combination second end, 3. tighten mother, 4. seal washer, 5. nipple.
Embodiment:
Nipple 5 is that cast steel material is formed, be cylindrical body, diameter is 25mm, long 20mm, be processed with screw thread outward, be cast as one with combination first end 1, combination second end 2 respectively, combination first end 1, combination second end 2, to tighten female 3 all be to form with cast steel material, combination first end 1, combination second end 2 by seal washer 4 with tighten female 3 and be connected.Combination first end 1 becomes reverse with silking in the nipple 5 of making up second end 2 two ends.
During use, nipple 5 connects with other pipe fitting, put seal washer 4 then after, will make up first end 1 and make up second end 2 and link together with tightening female 3.
Claims (2)
1, a kind of combined live joint by combination first end 1, combination second end 2, tighten female 3, seal washer 4 and forms, is characterized in that described combination first end 1, makes up second end 2 outer end connection parts nipple 5 is arranged.
2, a kind of combined live joint according to claim 1 is characterized in that described nipple 5 is made up of with combination first end 1, combination second end 2 cast steel material to be cast in.
