Abstract
The utility model discloses a quincunx expansion joint and relates to an expansion joint. The quincunx expansion joint comprises a body (1), a sealing ring (2), a quincunx gland (3), a stud (4) and anut (5), wherein the sealing ring (2) is arranged in the connecting part of the body (1) and the quincunx gland (3); the body (1) is connected with the quincunx gland (3) through the stud (4); and oneend of the stud (4) is fastened through the nut (5). The strength of the quincunx expansion joint is absolutely larger than that of a thermal pipe, the anticorrosion treatment is carried out on the inner wall, new material is used for filling, the cost is lowered, the service life is prolonged, the sealing performance is good, the stress effect is good, the surface is smooth, and the wear resistance is good.
Description
Technical field:
The utility model relates to a kind of expansion joint, especially a kind of quincunx expansion joint.
Background technique:
Expansion joint is the new product that equipment such as pump, valve, pipeline are connected with pipeline, by full bolt they is coupled together, and makes its one-tenth as a whole, and certain displacement amount is arranged, and when work, can pass end thrust also to whole tubing.So not only increase work efficiency, and pipe-line equipments such as pump, valve are played certain protective role.Yet the intensity that a lot of expansion joints are arranged at present not enough, and the pressure that bears is limited, and stress is concentrated, and effect is undesirable, and product surface is smooth inadequately, and wear resistance is not high, and working life is shorter.
The model utility content:
The purpose of this utility model provides a kind of quincunx expansion joint, and its intensity is definitely greater than heat distribution pipeline intensity, and it has done preservative treatment on inwall and filler uses new material, reduce cost, increase the service life, good seal performance, stress effect is good, smooth surface, and wear resistance is good.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it is made up of body 1, seal ring 2, quincunx gland 3, double-screw bolt 4 and nut 5, seal ring 2 is arranged on the inside, joint of body 1 and quincunx gland 3, body 1 is connected with quincunx gland 3 usefulness double-screw bolts 4, and fastening with nut 5 at an end of double-screw bolt 4.
Intensity of the present utility model is definitely greater than heat distribution pipeline intensity, and it has done preservative treatment on inwall and filler uses new material, reduces cost, increase the service life, and good seal performance, stress effect is good, smooth surface, wear resistance is good.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is that the A of Fig. 1 is to view.
Embodiment:
With reference to Fig. 1-2, this embodiment is by the following technical solutions: it is made up of body 1, seal ring 2, quincunx gland 3, double-screw bolt 4 and nut 5, seal ring 2 is arranged on the inside, joint of body 1 and quincunx gland 3, body 1 is connected with quincunx gland 3 usefulness double-screw bolts 4, and fastening with nut 5 at an end of double-screw bolt 4.
The intensity of this embodiment is definitely greater than heat distribution pipeline intensity, and it has done preservative treatment on inwall and filler uses new material, reduces cost, increase the service life, and good seal performance, stress effect is good, smooth surface, wear resistance is good.
