Description

Technical Field

[0001] The present invention relates to the field of plastic drainage pipe fittings, and particularly to an anti-pollution connection process for a sound insulation pipe. Background Art

[0002] In existing buildings, the drainage system is an essential supporting facility, and the noise of the drainage system directly affects the living environment of residents. Pipes are the main components of the drainage system, and good pipes can ensure the safety and stability of the drainage system. With the improvement of people's requirements for the quality of life and environmental protection, the requirements for the water supply system have also increased. In addition to requiring the pipe performance of the water treatment system to be safe and stable, modern people also pay attention to the noise problem of pipes.

[0003] The structure of the existing sound insulation pipe, such as the Chinese Patent Application No.: 201310073275.3, discloses a double-wall spiral sound insulation pipe, including a pipe body. The pipe wall is a connected double layer, and there are evenly arranged spaced through holes between the inner and outer walls. Guide ribs are uniformly provided along the inner pipe wall. When in use, the water flow falls in a spiral shape under the guiding action of the inner pipe wall, and under the dual action of multi-hole sound insulation on the double wall, the noise of the pipeline system can be reduced. Moreover, the water flow in the drainage riser shows an obvious wall-attached flow, reducing the water flow velocity, decreasing the water tongue resistance coefficient, keeping the central air core in the riser unobstructed up and down, stabilizing the pressure fluctuation in the pipe, improving the drainage capacity of the riser, reducing the drainage volume. At the same time, due to the unobstructed air column in the pipe, the pressure and pressure fluctuation in the pipe are reduced, and the safety factor of the pipeline use is improved.

[0004] However, there is no special structural component for connecting two sound insulation pipes in the existing market. Instead, traditional two-way pipe fittings or three-way pipe fittings are used for connection, resulting in the following problems:

[0005] Since the spaced through holes on the end face of the sound insulation pipe are in an open state and the thickness of the sound insulation pipe is relatively large, when using traditional two-way pipe fittings or three-way pipe fittings for connection, the spaced through holes are exposed in the flow channel. During the drainage process, the water flow will pour into the spaced through holes or impurities (such as hair, threads, branches, etc.) will be stuck at the spaced through holes, reducing the sound insulation effect of the sound insulation pipe and easily causing pipeline blockage. Summary of the Invention

[0006] Therefore, in view of the above problems, the present invention provides an anti-pollution connection process for a sound insulation pipe that is suitable for connecting sound insulation pipes to ensure the sound insulation effect and avoid blockage.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] An anti-pollution connection process for a sound insulation pipe, including a sound insulation pipe, a collar, and a connecting pipe fitting. The connection process includes the following steps:

[0009] (1) Insert the collar into the connection port of the connecting pipe fitting;

[0010] (2) Apply glue to one end face and the outer surface of the sound insulation pipe;

[0011] (3) Align and position the sound insulation pipe in step (2) with the connection port of the connecting pipe fitting, keep the central axis of the sound insulation pipe coincident with the central axis of the connecting pipe fitting, and initially press manually to make the initial section of the sound insulation pipe embed into the connection port of the connecting pipe fitting;

[0012] (4) Then push the sound insulation pipe to squeeze the collar inward to the installation position, so that the end face of the collar covers the through hole of the sound insulation pipe.

[0013] Further, the collar includes a first annular portion and a second annular portion connected integrally. Both the first annular portion and the second annular portion are semi-elliptical structures. The short-axis dimension of the first annular portion is equal to the long-axis dimension of the second annular portion and they coincide with each other. The ratio of the long-axis dimension to the short-axis dimension of the first annular portion is 1:0.93 - 0.98, and the ratio of the long-axis dimension to the short-axis dimension of the second annular portion is 1:0.97.

[0014] Further, the sound insulation pipe includes an outer wall, an inner wall, and a plurality of through holes uniformly distributed between the outer wall and the inner wall. The connecting pipe fitting has at least two connection ports and a flow channel connecting the connection ports. A raised portion is provided in the flow channel, so that there is a limiting end face at the position of the flow channel facing each connection port. One end of the collar and the sound insulation pipe are embedded in the connection port of the connecting pipe fitting, and the collar is clamped between the sound insulation pipe and the limiting end face.

[0015] Further, the thickness dimension of the collar is equal to the thickness dimension of the sound insulation pipe.

[0016] Further, the axial length dimension of the collar is 5 cm - 15 cm.

[0017] Further, the thickness dimension of the raised portion is not greater than the thickness dimension of the collar.

[0018] Further, a plurality of first convex strips are uniformly distributed around the inner surface of the inner wall, and the first convex strips are spirally distributed.

[0019] Further, at least one second convex strip is distributed between adjacent two of the first convex strips on the inner surface of the inner wall, and the second convex strips are spirally distributed. The cross-sectional area of the second convex strip is smaller than the cross-sectional area of the first convex strip.

[0020] Further, two second convex strips are distributed between adjacent two of the first convex strips, and the distance between the two second convex strips is smaller than the distance between the second convex strip and its adjacent first convex strip.

[0021] By adopting the foregoing technical solution, the beneficial effects of the present invention are as follows: In this soundproof pipe anti-pollution connection process, the provided collar is clamped between the connecting pipe fitting and the soundproof pipe, and the end face of the collar covers the through hole of the soundproof pipe, thereby isolating the through hole of the soundproof pipe, preventing water flow from pouring into the through hole or debris from getting stuck at the through hole and causing blockage, and ensuring the noise reduction effect of the soundproof pipe. With such a design, the thickening treatment of the convex part in the connecting pipe fitting can be avoided, and it can be applicable to the conventional connecting pipe fittings sold on the market, reducing the use cost. During use, the collar is pre-embedded into the connection port of the connecting pipe fitting first, and then one end of the soundproof pipe is smeared with glue and inserted into this connection port to be fixedly connected with the collar and the connecting pipe fitting. The structure is simple, the operation is convenient, and the connection strength is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0033] An embodiment of the present invention is as follows:

[0034] Reference Figures 1 to 4 As shown, a sound insulation pipe anti-pollution connection process is characterized by comprising a sound insulation pipe 1, a collar 2 and a connecting pipe fitting 3. The connection process comprises the following steps:

[0035] (1) Embed the collar 2 into the connection port 31 of the connecting pipe fitting 3;

[0036] (2) Apply glue to one end face and the outer surface of the sound insulation pipe 1;

[0037] (3) Align and position the sound insulation pipe 1 in step 2 with the connection port 31 of the connecting pipe fitting 3 through the installation device 10, keep the central axis of the sound insulation pipe 1 coincident with the central axis of the connecting pipe fitting 3, and initially press manually to make the initial section of the sound insulation pipe 1 embed into the connection port 31 of the connecting pipe fitting 3;

[0038] (4) Then push the sound insulation pipe 1 through the installation device 10 to squeeze the collar 2 inward to the installation position, so that the end face of the collar 2 covers the through hole 13 of the sound insulation pipe 1.

[0039] In this sound insulation pipe anti-pollution connection process, the arranged collar 2 is clamped between the connecting pipe fitting 3 and the sound insulation pipe 1, and the end face of the collar 2 covers the through hole 13 of the sound insulation pipe 1, thereby isolating the through hole 13 of the sound insulation pipe 1, avoiding water flow pouring into the through hole 13 or sundries being stuck at the through hole 13 to cause blockage, and ensuring the noise reduction effect of the sound insulation pipe 1. With such a design, the thickening treatment of the convex part 33 in the connecting pipe fitting 3 is avoided, and it can be applicable to the conventional connecting pipe fittings sold on the market, reducing the use cost. When in use, first embed the collar 2 into the connection port 31 of the connecting pipe fitting 3, then apply glue to one end of the sound insulation pipe 1 and insert it into the connection port 31 to be fixedly connected with the collar 2 and the connecting pipe fitting 3. The structure is simple, the operation is convenient, and the connection strength is high.

[0040] In this embodiment, the silencing pipe 1 includes an outer wall 11, an inner wall 12, and a plurality of through holes 13 evenly distributed between the outer wall 11 and the inner wall 12. The connecting pipe fitting 3 has at least two connecting ports 31 and a flow channel 32 communicating with each connecting port 31. In this embodiment, the connecting pipe fitting 3 has two connecting ports 31. Of course, in actual applications, it can also have three or four connecting ports, which is determined according to actual application needs. A raised portion 33 is provided in the flow channel 32, so that a limiting end face 34 is formed on the flow channel 32 facing each connecting port 31. One end of the collar 2 and the silencing pipe 1 is embedded in the connecting port 31 of the connecting pipe fitting 3, and the collar 2 is clamped between the silencing pipe 1 and the limiting end face 34. The end face of the collar 2 covers the through hole 13 of the silencing pipe 1. Specifically, the thickness dimension of the collar 2 is equal to the thickness dimension of the silencing pipe 1, and the axial length dimension of the collar 2 is 5 cm to 15 cm. Preferably, the axial length dimension of the collar 2 is 8 cm, which is convenient for the collar 2 to be fitted and embedded with the connecting pipe fitting 3, and can better save costs and ensure the connection strength between the silencing pipe 1 and the connecting pipe fitting 3.

[0041] Moreover, the thickness dimension of the raised portion 33 is not greater than the thickness dimension of the collar 2. Preferably, the thickness dimension of the raised portion 33 is 3 mm to 8 mm smaller than the thickness dimension of the collar 2. Specifically, the thickness dimension of the raised portion 33 is 4 mm smaller than the thickness dimension of the collar 2, so as to be applicable to the conventional connecting pipe fitting 3. An annular groove 6 can be formed by the thickness difference between the raised portion 33 and the collar 2, thereby balancing the pressure in the silencing pipe 1, enabling the air carried in the water flow attached wall flow to be squeezed into the annular groove 6, reducing noise. Moreover, a plurality of first convex strips 4 are evenly distributed on the inner surface of the inner wall 12 in a spiral distribution. Two second convex strips 5 are distributed between adjacent two of the first convex strips 4 on the inner surface of the inner wall 12 in a spiral distribution. The cross-sectional area of the second convex strip 5 is smaller than the cross-sectional area of the first convex strip 4. Two second convex strips 5 are distributed between adjacent two of the first convex strips 4, and the distance between the two second convex strips 5 is smaller than the distance between the second convex strip 5 and its adjacent first convex strip 4, further improving the effect of the drainage attached wall flow, improving the steady flow effect of the drainage flow, reducing the water flow velocity, reducing the water tongue resistance coefficient, keeping the central air core in the vertical pipe unobstructed up and down, stabilizing the pressure fluctuation in the pipe, and improving the drainage capacity of the vertical pipe.

[0042] Reference Figure 5 、 Figure 6 And Figure 7As shown, the above-mentioned first convex strip 4 and second convex strip 5 are fixedly arranged on the inner surface of the inner wall 12 of the sound-absorbing pipe 1, that is, integrally formed with the sound-absorbing pipe 1. During the forming process, the mold core or the sound-absorbing pipe 1 needs to rotate, so that the first convex strip 4 and the second convex strip 5 form a spiral structure, and its forming is difficult and the equipment is expensive. Therefore, the applicant makes the following improvements to reduce the production cost;

[0043] Specifically, a plurality of water-following components 7 are arranged inside the sound-absorbing pipe 1, and the water-following components 7 are sequentially distributed along the axial direction of the sound-absorbing pipe 1. The water-following component 7 includes an upper ring 71, a lower ring 72, and a first connecting strip 73 and a second connecting strip 74 connected between the upper ring 71 and the lower ring 72. The outer ends of the upper ring 71 and the lower ring 72 are respectively provided with a positioning block 75 and a positioning groove 76 that cooperate with each other, so that the first connecting strips 73 on each water-following component 7 are connected to form the first convex strip 4, and the second connecting strips 74 on each water-following component 7 are connected to form the second convex strip 5. When in use, the water-following component 7 is embedded in the sound-absorbing pipe 1, and is positioned by the cooperation of the positioning block 75 and the positioning groove 76 on the adjacent upper ring 71 and lower ring 72, so that the first connecting strips 73 on each water-following component 7 are connected to form the first convex strip 4, and the second connecting strips 74 on each water-following component 7 are connected to form the second convex strip 5. Furthermore, the first convex strip 4 and the second convex strip 5 are movably connected to the sound-absorbing pipe 1. When there is a large water flow, due to the first convex strip 4 and the second convex strip 5, the water flow adheres to the wall and flows. Under the impact of the large water flow, it reacts on the water-following component 7, drives it to rotate, reduces the potential energy of the water flow, further improves the wall-flow effect, improves the steady-flow effect of the drainage flow, reduces the water flow velocity, reduces the water tongue resistance coefficient, keeps the central air core in the vertical pipe unobstructed up and down, stabilizes the pressure fluctuation in the pipe, and improves the drainage capacity of the vertical pipe.

[0044] Reference Figure 8 As shown, it should be noted that the collar 2 includes a first annular portion 21 and a second annular portion 22 that are integrally connected. Both the first annular portion 21 and the second annular portion 22 are semi-elliptical structures. The short-axis a dimension of the first annular portion 21 is equal to the long-axis b dimension of the second annular portion 22 and they overlap with each other. The ratio of the long-axis c dimension to the short-axis a dimension of the first annular portion 21 is 1:0.93 to 0.98, preferably 0.98. The ratio of the long-axis b dimension to the short-axis d dimension of the second annular portion 22 is 1:0.97, so that the collar 2 forms a line contact with the inner wall 12 of the connecting pipe fitting 3 and has three support lines, which can better support the collar 2, prevent it from shifting, and is preferably positioned and installed at the connection port 31 of the connecting pipe fitting 3. At the same time, it is convenient for the collar 2 to move and rotate, so that the sound-absorbing pipe 1 can be slightly adjusted during installation, and the connection strength of the connecting pipe fitting 3, the sound-absorbing pipe 1 and the collar 2 is improved.

[0045] On the inner wall 12 of the silencing pipe 1 and at a position opposite to one of the through holes 13, a groove 8 is recessed. The groove 8 is distributed along the axial direction of the silencing pipe 1, which can squeeze the air carried in the wall-attached flow of water into the groove 8, reduce noise, and improve the effect of the wall-attached flow.

[0046] In this embodiment, with reference to Figure 9 and Figure 10 As shown, the installation device 10 includes a support base 101, a left clamping arm 102 and a right clamping arm 103 distributed at one end of the support base 101, a left clamping sleeve 104 and a right clamping sleeve 105 distributed at the other end of the support base 101, a screw 106, a nut sleeve 107 provided on the support base 101, and a connecting seat 108 rotatably provided on the screw 106. The middle parts of the left clamping arm 102 and the right clamping arm 103 are hinged to the support base 101. Grips 109 are provided on the upper parts of the left clamping arm 102 and the right clamping arm 103. Clamping parts 110 for clamping the connecting pipe fitting 3 are provided on the lower parts of the left clamping arm 102 and the right clamping arm 103. A guide plate 111 is provided in the middle of the left clamping arm 103. A guide groove 112 is provided on the guide plate 111. Rack teeth 113 arranged in a row are provided in the guide groove 112. A latch 114 cooperating with the rack teeth 113 is hinged in the middle of the right clamping arm 103. The upper ends of the left clamping sleeve 104 and the right clamping sleeve 105 are hinged to the connecting seat 108. The lower ends of the left clamping sleeve 104 and the right clamping sleeve 105 are locked by bolts 115 for clamping the silencing pipe 1. A handle 116 is provided at the free end of the screw 106.

[0047] When in use, hold the grips 109 of the left clamping arm 102 and the right clamping arm 103 by hand, clamp the connecting pipe fitting 3 through the clamping parts 110, and place the latch 114 on the rack teeth 113, and then place it through the edge 20 at the outer end of the connecting pipe fitting 3, so that the left clamping arm 102 and the right clamping arm 103 are fixed. Then clamp the silencing pipe 1 through the left clamping sleeve 104 and the right clamping sleeve 105, and pre-lock it through the bolts 115, so that the connection port 31 of the connecting pipe fitting 3 is positioned and calibrated with the silencing pipe 1, and then lock and clamp the silencing pipe 1. Finally, rotate the screw 106 through the handle 116 to move axially along the nut sleeve 107, thereby driving the left clamping sleeve 104 and the right clamping sleeve 105 to clamp the silencing pipe 1 and embed it into the connection port 31 of the connecting pipe fitting 3. Its structure is simple and it is convenient to use.
