Abstract

The utility model discloses an inclined tee-joint tubular product comprising a first port, a second port and an inclined port. An acute included angle is formed between the first port side wall close to one side of the inclined port and the inclined port side wall close to one side of the first port; fillet conduction is performed to the acute angle; the thickness of the first port side wall close to the side wall of the inclined port is larger than the thickness of the rest side walls; and a distance between a starting point of the fillet on the inclined port side wall and the first port far away the inclined port side wall is smaller than the internal diameter of the second port. The inclined tee-joint tubular product can effectively solve a problem of stress concentration of intersecting line parts of a pipe, so the stress concentration can be decreased by around 25% to 30% with only 5% to 7% increase of pipe weight; the inclined tee-joint tubular product has obvious effect and overall strength of the pipe can be effectively enhanced; and the inclined tee-joint tubular product is simply structured with easy promotion, small difficult of die manufacturing and incapability of reversion.

Description

A kind of skew T tubing

Technical field

The utility model relates to threeway tubing field, more specifically, relates to a kind of skew T tubing.

Background technique

45 ° of skew Ts are a kind of conventional plastic pipes, it is widely used in building, oil, chemical industry, electric power, boats and ships, weaving, the industries such as food, due to its structural feature, at pipe fitting intersecting line position, have sharp wedge angle, therefore easily produce larger stress and concentrate, wedge angle will produce fine cracks under the effect of long-term hydrostatic pressing, crackle spreads gradually and then causes pipe fitting fracture failure, when serious, will produce security incident.In order to reduce the stress at intersecting line wedge angle position, concentrate, some people directly increases the whole wall thickness of pipe fitting, tend to like this cause cost to increase considerably, and effect is not clearly; Some people is directly at intersecting line wedge angle position rounding, and so effectively relieve stresses is concentrated, but fillet position exists back-off problem, and product cannot depanning.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of property skew T tubing is provided, and it is concentrated that this tubing can be alleviated intersecting line position stress, does not increase again a kind of structure of the manufacture difficulty of mould, and cost increases little.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of skew T tubing, comprise the first port, the second port and oblique port, the sidewall of the close tiltedly port side of the first port and tiltedly port are acute angle near the sidewall angle of the first port side, fillet processing is carried out in described angle, and the first port is greater than the thickness of all the other sidewalls near the thickness of the sidewall of oblique port side; The starting point that described fillet is positioned on oblique port sidewall is less than or equal to the internal diameter of the second port away from the distance of oblique port sidewall to the first port.

The partial sidewalls thickening of this skew T tubing, alleviates intersecting line position stress and concentrates, and by the control to fillet height, has avoided the problem of back-off.

As a kind of preferred version, described the first port is greater than the first port away from the oblique thickness of the sidewall of port near the oblique thickness of the sidewall of port side, and is less than or equal to the first port away from 2 times of the thickness of the oblique sidewall of port.

As a kind of preferred version, described skew T tubing is pipe.

As a kind of preferred version, described the first port near the thickness of the oblique sidewall of port side along the symmetry plane of skew T tubing by successively decreasing to two weeks.The symmetry plane of described skew T tubing is formed of the axis of oblique port and the first port, the second port axis.

As a kind of preferred version, described angle is 45 °.Be 45 ° of skew T tubing.

Compared with prior art, the utlity model has following beneficial effect:

The utility model can effectively be alleviated pipe fitting intersecting line position problem of stress concentration, stress can be concentrated to 25% ~ 30% left and right that declines, but the weight of pipe fitting only increases by 5% ~ 7%, effect highly significant, and the bulk strength of pipe fitting has obtained effective raising.The utility model is simple in structure, be easy to promote, and Mould Machining manufacture difficulty is little, does not have back-off problem.

Accompanying drawing explanation

Fig. 1 is the structural representation of skew T tubing described in embodiment 1;

Fig. 2 is the fillet partial enlarged drawing of skew T tubing described in embodiment 1.

Embodiment

Below in conjunction with embodiment, the utility model is further described.Wherein, accompanying drawing is only for exemplary illustration, expression be only schematic diagram, but not pictorial diagram can not be interpreted as the restriction to this patent; For embodiment of the present utility model is described better, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; For a person skilled in the art, in accompanying drawing some known configurations and explanation thereof may to omit be understandable.

The corresponding same or analogous parts of same or analogous label in the utility model embodiment's accompanying drawing, in description of the present utility model, it will be appreciated that, if have term " on ", D score, " left side ", orientation or the position relationship of indications such as " right sides " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, rather than device or the element of indication or hint indication must have specific orientation, with specific orientation structure and operation, therefore the term of describing position relationship in accompanying drawing is only for exemplary illustration, can not be interpreted as the restriction to this patent, for the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.

Embodiment 1

Described in the present embodiment, bevel arm piece equipment structure as shown in Figure 1, a kind of skew T pipe, comprise the first port, the second port and oblique port, the sidewall 1 of the close tiltedly port side of the first port and tiltedly port are acute angle near sidewall 2 angles of the first port side, fillet processing is carried out in described angle, described the first port is greater than the first port away from the thickness of the sidewall of oblique port near the thickness of the sidewall of oblique port side, and is less than or equal to the first port away from the twice of the thickness of the sidewall of oblique port.Starting point 3 to first ports that described fillet is positioned on oblique port sidewall are less than the internal diameter of the second port away from the distance of oblique port sidewall.

Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all mode of executions.All any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in the protection domain of the utility model claim.
