Abstract

The utility model relates to a tube fitting, in particular to a right-angled internal-threaded elbow for concealed construction. The elbow comprises a metal connector sleeve, a bent tube section and an external-connected tube section, a straight tube section is arranged between the metal connector sleeve and the bent tube section, and the straight tube section, the bent tube section and the metal connector sleeve are connected to form an integrated structure. The utility model has the following advantages that: since the straight tube section is added, when the right-angled internal-threaded elbow is used in the concealed construction of residential decoration under cement and ceramic tiles, the connection of other fittings and man-hours are reduced, in addition, because of the addition of the straight tube section, the thickness of the cement substrate in the concealed construction is increased as well, and thereby tubes cannot be easily damaged during construction or reparation.

Description

Concealed work right angle internal thread elbow
Technical field
The utility model relates to a kind of pipe fitting accessory, specifically refers to a kind of right angle internal thread elbow that is suitable for using in the concealed work.
Background technique
Right angle internal thread elbow is usually used in being used for being connected of pipeline and metal threaded accessory etc.Be common right angle internal thread elbow sectional view as shown in Figure 1.As shown in Figure 1, this right angle internal thread elbow is mainly by metal connecting piece sleeve pipe, bent angle pipeline section with outreach pipeline section and form, the metal connecting piece sleeve pipe of one end is connected such as the fire hose is first-class with the external metallization threaded fittings by the internal thread of embedded metal link, and the other end is connected with other pipelines by outreaching pipeline section.Right angle internal thread elbow is common in the concealed work and uses, is installed in the body of wall such as right angle internal thread elbow, and interior water receiving pipe pipeline, the external fire hose is first-class.But from Fig. 1 as seen and since right angle internal thread elbow to contain the internal thread segment duct length not enough, promptly stretch out the body of wall curtailment, when laying situation such as ceramic tile at body of wall, also to connect other accessories to pick out surface engineering, cause accessory too much, inconvenience is installed.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of concealed work right angle internal thread elbow is provided, design a straight length, promptly elongated the length of internal thread elbow corner, right angle pipe fitting, when in concealed work, using owing to added a straight length, make the thickness of this part cement base part increase, when ceramic tile is repaired, can not damage conduit pipeline, stop water leakage phenomenon.
The purpose of this utility model realizes being finished by following technological scheme:
A kind of concealed work right angle internal thread elbow, by metal connecting piece sleeve pipe, bent angle pipeline section with outreach pipeline section and form, be provided with a straight length between described metal connecting piece sleeve pipe and bent angle pipeline section, described straight length is connected with bent angle pipeline section and metal connecting piece sleeve pipe and is integrative-structure.
Above-mentioned bent angle pipeline section, with the inwall that outreaches the end that pipeline section is connected on have a location boss, the positioning boss lower end surface is set to be acute angle-shaped with the pipeline water (flow) direction.
The utility model has the advantages that, by adding straight length, make the concealed work of right angle internal thread elbow under cement that is used for house decoration and ceramic tile, the accessory that has reduced other connects and artificial man-hour, in addition, add straight length, also just increased the thickness of cement base part in the concealed work, engineering construction or the not fragile constantly pipeline of maintenance.
Description of drawings
Fig. 1 is a prior art right angle internal thread elbow sectional view;
Fig. 2 is the utility model right angle internal thread elbow mounting structure schematic representation.
Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Label 1-8 representative is to outreach pipeline section 1, bent angle pipeline section 2, metal connecting piece sleeve pipe 3, metal connecting piece 4, positioning boss 5, straight length 6, concealed work cement base part 7, concealed work ceramic tile part 8 among the accompanying drawing 1-2.
Be illustrated in figure 1 as prior art right angle internal thread elbow sectional view.As seen from Figure 1, divide according to two vertical among figure phantom line segments, right angle internal thread elbow is mainly by metal connecting piece sleeve pipe 3, bent angle pipeline section 2 with outreach pipeline section 1 three parts and form, metal connecting piece sleeve pipe 3 is embedded with metal connecting piece 4, metal connecting piece 4 has internal thread, can be connected with the external metallization threaded fittings.The outreaching pipeline section 1 and can be connected of the right angle internal thread elbow the other end with other pipelines.
Right angle internal thread elbow is common in the concealed work and uses, such as right angle internal thread elbow is installed in the body of wall, and interior water receiving pipe pipeline, the external fire hose is first-class.But from Fig. 1 as seen and since right angle internal thread elbow to stretch out wall part length not enough, lay at body of wall under the situation such as ceramic tile finishing, right angle internal thread elbow also will connect other accessories and pick out surface engineering, this just causes accessory too much, installs not convenient.
In the present embodiment, between metal connecting piece sleeve pipe 3 and bent angle pipeline section 2, be provided with a straight length 6, promptly elongated right angle internal thread elbow and stretched out wall part length, shown in accompanying drawing 2 the utility model right angle internal thread elbow mounting structure schematic representation.Compared to the right angle internal thread elbow of Fig. 1, the right angle internal thread elbow in the present embodiment obviously stretches out wall part lengthening, and the straight length 6 that adds is structure as a whole with bent angle pipeline section 2 and metal connecting piece sleeve pipe 3, and design is produced and is easy to accomplish.
As seen from Figure 2, when concealed work was installed and used, straight length 6 parts were positioned at concealed work cement base part 7, had increased the thickness of concealed work cement base part 7, also increased simultaneously the anti-bearing capacity of right angle internal thread elbow Vertical direction, made that installation is more firm, firm.Metal connecting piece sleeve pipe 3 parts fully are hidden in the concealed work ceramic tile part 8, accomplish to install neatly, and aesthetic is good.
In addition, as shown in Figure 1, with outreach bent angle pipeline section 2 one ends that pipeline section 1 is connected, have a location boss 5 on its inwall, when it act as and is connected with external pipe, external pipe inserted and outreaches in the pipeline section 1, is positioned to encircle boss.Boss shape as shown in Figure 1, boss lower end surface and pipeline water (flow) direction meet at right angles, though so more help locating when external pipe inserts and connecting, but because external pipe is to be connected by fusion with outreaching between the pipeline section, material extrusion is too much stretched along the boss lower end surface easily outward during use, melt condenses and causes the pipeline water flow section to diminish, and water flow pressure increases, even results in blockage, leaks.
The interior dotted arrow of pipeline is represented water (flow) direction among Fig. 2, in the present embodiment, positioning boss 5 lower end surfaces are set to be acute angle-shaped with the pipeline water (flow) direction, 60 degree angles as shown in Figure 2, be that boss 5 lower end surfaces and pipeline water (flow) direction angle are 30 degree, material extrusion is crossed many parts and can evenly be disperseed along plane of inclination, boss 5 lower end surface during use, and unlikely resulting in blockage increases right angle internal thread elbow and bear water flow pressure.
