Abstract
The utility model relates to the pipe joint of iron-base shape memory alloy. The inner wall of the pipe joint body made of iron-base shape memory alloy is provided with grooves, and sealing ribs are arranged between the adjacent grooves; the surfaces of the ribs and the grooves are provided with anticorrosive coatings; sealing material is filled in the grooves on both ends. The material adopted through the pipe joint of iron-base shape memory alloy is cheap and has low cost; pipes are tightly connected, and the sealing performance is good; the use is convenient and reliable; the pipe joint of iron-base shape memory alloy can takes the place of a threaded pipe joint or the welding. The pipe joint of iron-base shape memory alloy is suitable for the connection of various pipelines.
Description
The utility model belongs to a kind of pipe joint, particularly a kind of pipe joint made from the iron-base marmem material.
The pipe joint that in the connection of pipeline, uses at present, great majority are that materials such as steel, cast iron, aluminum alloy are made, its pipe joint inwall is with the spiral shell button.During use, add sealing material by the spiral shell button pipe is connected, the then employing flange that has connects.Its deficiency is: spiral shell link connect not tight, thereby poor sealing; Can not replace welding; As slide fastener or get rusty, promptly become waste product, thereby utilization ratio is not high in the use; Connect with flange, waste material uses inconvenient.
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of iron-base marmem pipe joint is provided.
The purpose of this utility model is achieved in that
The internal diameter of the pipe joint made from the iron-base marmem material is greater than the external diameter of connected pipe, and the inwall of pipe joint has groove, between groove and the groove sealed muscle is arranged, and there is underseal on the surface of muscle and groove, in first groove at its two ends sealing compound is housed.
The internal diameter of the pipe joint made from the iron-base marmem material is greater than the external diameter of connected pipe, and the inwall two ends of pipe joint have 3～4 grooves, and 2～3 sealed muscles are arranged between groove and the groove, and there is a sealing strip at its middle part.There is underseal on the surface of muscle, band and groove.In first groove at its two ends sealing compound is housed.
Description of drawings is as follows:
Fig. 1 is first kind of mode of execution structural representation of the utility model pipe joint.
Fig. 2 is second kind of mode of execution structural representation of the utility model pipe joint.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
First embodiment's of iron-base marmem pipe joint structure is, has groove 2 at the inwall of the pipe joint body made from the iron-base marmem material 1, sealed muscle 3 arranged between groove and the groove, and scribble underseal 4 on the surface of sealed muscle and groove.In first groove at pipe joint inwall two ends, sealing compound 5 is housed respectively.Its structure as shown in Figure 1.
Second embodiment's structure as shown in Figure 2; At the inwall of the pipe joint body made from the iron-base marmem material 1, its two ends have three grooves 2, and two sealed muscles 3 are arranged between groove and the groove, and its middle part is a sealing strip 6.The surface of muscle, band and groove scribbles underseal 4, in first groove at its two ends sealing compound 5 is housed respectively.
The internal diameter of pipe joint can connect the size of tube outer diameter as required all greater than the external diameter that is connected pipe, makes the pipe joint of different size internal diameter.To the corrosion resistance no requirement (NR), the pipe joint inwall can not be coated with underseal as Environmental Conditions.
Owing to make the material iron-base marmem of pipe joint shape memory function is arranged at a certain temperature, thereby, during use, pipe joint is enclosed within on the two tubes that needs to connect, after low-temperature heat, pipe joint can shrink automatically, and two tubes is linked together closely.
The utility model compared with prior art has the following advantages:
The tubing iron-base marmem of selecting is inexpensive, thereby cost is low; Pipe connects closely, and good airproof performance; Easy to use, reliable; Can replace being threaded or welding.
Claims (2)
1, a kind of pipe joint, it is characterized in that: the internal diameter of the pipe joint made from the iron-base marmem material is greater than the external diameter of connected pipe, the inwall of pipe joint has groove, between groove and the groove sealed muscle is arranged, there is underseal on the surface of muscle and groove, in first groove at its two ends sealing compound is housed.
2, according to the said pipe joint of claim 1, it is characterized in that: pipe joint inwall two ends have 3～4 grooves, and 2～3 sealed muscles are arranged between groove and the groove, and there is a sealing strip at its middle part.
