Abstract
The utility model relates to a flaring plug for a pipeline. The flaring plug for the pipeline mainly comprises a plug head, an external thread portion, an outer conical surface and an inner hole; the plug head is located on one end of the plug, the outer conical surface is located on the other end of the plug, a cylinder is located between the plug head and the outer conical surface, the outer thread portion is installed on the outer surface of the cylinder, and the inner hole is formed inside the cylinder; and the conical degree of the outer conical surface generally ranges from 70 to 75 degrees, and when the conical degree of the outer conical surface is 74 degrees, the best sealing effect is achieved. The flaring plug for the pipeline is simple in structure and convenient to process, mass production can be achieved through standard machining methods, any special processing technique is not needed, implementation is easy, effects are obvious, and the flaring plug for the pipeline can be popularized and applied to various machinery industries.
Description
Technical field
The utility model belongs to mechanical manufacturing field, and particularly the enlarging used of a kind of blocking pipe is stopped up.
Background technique
Stopping up, also claim plug screw, is a kind of common part of blocking pipe.The common structure that stops up as shown in Figure 1.Along with the fast development of modern industry, owing to consider that fluid pressure is large in the pipeline, the requirement of pipeline connection reliability is higher, present pipeline connecting parts majority is towards the inside and outside conical surface connecting direction development of flared type.
The model utility content
The technical problems to be solved in the utility model provides the enlarging obstruction that the higher blocking pipe of a kind of reliability is used.
A kind of pipeline stops up with enlarging, mainly comprises plug, male thread portion, male cone (strobilus masculinus), endoporus; Plug is positioned at an end of obstruction, and male cone (strobilus masculinus) is positioned at the other end of obstruction, and one section cylindrical body is arranged between plug and male cone (strobilus masculinus), and cylindrical outer surface is provided with male thread portion, is provided with endoporus in the cylindrical body; The tapering of male cone (strobilus masculinus) is generally 70～75 degree.When the tapering of male cone (strobilus masculinus) is that 74 sealing effects when spending are best.
The utility model is simple in structure, easy to process, adopts the conventional machinery processing method can realize batch production, without any special processing process, and also easy to implement, successful can be popularized and applied to various machinery industries.
Description of drawings
Fig. 1 is the structural representation of common obstruction;
Fig. 2 is the left view that the utility model stops up;
Fig. 3 is the plan view that the utility model stops up;
Embodiment
At mechanical processing industry, obstruction is very common a kind of part, mainly is used in the places such as hydraulic system, pressure system.Such as Fig. 2, shown in Figure 3, the utility model provides a kind of novel enlarging to stop up, and it mainly comprises: plug 1, male thread portion 2, male cone (strobilus masculinus) 3, endoporus 4.Plug 1 is positioned at an end of obstruction, and male cone (strobilus masculinus) 3 is positioned at the other end of obstruction, and one section cylindrical body is arranged between plug 1 and male cone (strobilus masculinus) 3, and cylindrical outer surface is provided with male thread portion 2, is provided with endoporus 4 in the cylindrical body.The tapering of male cone (strobilus masculinus) 3 is generally 70～75 degree, through experiment showed, when tapering be 74 the bests of sealability when spending.
The utility model is processed into a male cone (strobilus masculinus) 3 to the end on the basis of common obstruction, be processed into blind hole shape endoporus 4 in the blockage body.The stifled body of plug is processed into blind hole, has alleviated on the one hand the stifled own wt of plug, can also hold highly pressurised liquid simultaneously and effectively disperse the direct effect area of highly pressurised liquid to connection part.When flared type stopped up and reliably to be fixedly connected with cap nut by outside thread part 2, the male cone (strobilus masculinus) 3 of obstruction and the inner conical surface of pipe joint were by " face-face Contact Pair " realization reliable sealing.Common obstruction only realizes sealing by screw thread, does not often reach due sealing effect.
The utility model enlarging is stopped up easy to process, adopts six square stocks, the direct planar end surface of clamping one end on lathe; Cylindrical turning; The car tool withdrawal groove; Threading; The car conical surface; Boring; Cut off and get final product.
Compared with prior art, the utility model is designed to common obstruction interior poroid, and weight alleviates greatly, is widely used in weight is had the fields such as Aeronautics and Astronautics of strict restriction, and better tightness has become first-selected essential zero spare part in some high pressure fields.
