Abstract
Description
Technical Field
[0001] The present application relates to the technical field of PPR pipe fittings, and in particular to a low water loss PPR pipe fitting. Background Art
[0002] There are a large number of tee fittings, elbow fittings and PPR fittings in the existing water supply system. PPR fittings have the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall and not easy to scale, simple construction and maintenance, and long service life.
[0003] PPR water pipes and tee fittings and elbow fittings (also made of PPR material) are usually fixed directly by hot melting to achieve pipeline interconnection. The main principle is to melt the materials at the connection between the two pipe fittings, mix them together and cool them to form a connection, thus eliminating the need for other adhesive materials. Although the hot melt connection method is simple and convenient, the melted material is liquid and will flow around during the extrusion process, causing the flowing material to not only form a circle of step-like structure on the outside of the pipe after cooling, affecting the overall appearance, but also flow to the inside of the pipe to form a circle of annular structure, causing the liquid flowing inside the pipe to be hindered to a certain extent by the obstruction of the annular structure, thereby causing greater water loss, which will reduce the stability of the water flow. Water loss refers to the mechanical energy loss per unit mass of liquid during the movement of water flow. In order to reduce water loss, the present application provides a low water loss PPR pipe fitting to solve the above problem. Utility Model Content
[0004] In response to the shortcomings of the prior art, the present application provides a low-water-loss PPR pipe fitting, which has the advantages of being able to make the interior of the pipe fitting smoother after hot-melt connection through structural settings, thereby greatly reducing water loss. This solves the problem that the interior of the existing PPR pipe fittings is not smooth enough after hot-melt connection, which causes the flow of liquid to be obstructed and thus causes greater water loss.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a low-water-loss PPR pipe fitting, comprising a connecting pipe fitting, a connecting end head is fixed on the outer side of the end of the connecting pipe fitting, a transition component for reducing water loss is installed on the inner side of the connecting pipe fitting, and a plurality of anti-slip strips are fixedly connected to the outer side of the connecting pipe fitting and the outer side of the connecting end head;
[0006] The transition assembly includes an annular transition block fixed to the inner side of the connecting pipe away from the connecting end, a first fillet opened between the outer side of the annular transition block away from the connecting end and the inner side of the connecting pipe, an annular bevel block fixed to the inner side of the connecting pipe close to the connecting end, and a second fillet opened between the outer side of the annular bevel block close to the connecting end and the inner side of the connecting pipe.
[0007] By adopting the above technical solution, the inside of the pipe after hot-melt connection is smoother, thereby greatly reducing water loss. At the same time, the structural setting can also buffer the passing water flow, further reducing water loss.
[0008] Furthermore, the number of the anti-slip strips is seven, and three anti-slip strips are fixed to the outer side of the connecting end, and the anti-slip strips are in the shape of long strips.
[0009] By adopting the technical solution, the anti-slip strip makes it easier to hold.
[0010] Furthermore, the outer side of the connecting pipe fitting away from the connecting end head has four anti-slip strips, and the four anti-slip strips on the outer side of the connecting pipe fitting away from the connecting end head are distributed in a circle.
[0011] By adopting the above technical solution, the anti-slip strip can facilitate the operator to hold the end of the connecting pipe or the end of the connecting end.
[0012] Furthermore, the interior of the annular transition block is communicated with the interior of the annular slope block, and the annular transition block and the annular slope block are connected to form a tubular structure.
[0013] By adopting the above technical solution, water liquid can circulate normally.
[0014] Furthermore, the connecting pipe is bent in an L-shape, and the tubular structure formed by connecting the annular transition block and the annular slope block is located at the inner curved part of the connecting pipe.
[0015] By adopting the above technical solution, water liquid can be transported normally.
[0016] Furthermore, the two ends of the tubular structure formed by connecting the annular transition block and the annular slope block extend to the two ends of the interior of the connecting pipe respectively.
[0017] By adopting the above technical solution, it is possible to reduce water loss of incoming water liquid.
[0018] Furthermore, a side of the annular bevel block away from the curved portion of the connecting pipe is a bevel, and the bevel of the annular bevel block is inclined toward a side close to the curved portion of the connecting pipe.
[0019] By adopting the above technical solution, the inclined slope can facilitate the passage of water and can buffer the water flow so that the water flow can remain stable.
[0020] Furthermore, the inner diameter of the annular slope block is equal to the inner diameter of the annular transition block.
[0021] By adopting the above technical solution, the internal water flow can be transported normally.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] The low water loss PPR pipe fittings, through the use of connecting pipe fittings, connecting ends and internal transition components, allow the liquid after hot melting to have a certain flow space, so that the molten PPR can be gathered inside the space, thereby avoiding the formation of an annular blocking structure on the inside, making the inside of the pipe fittings after hot melting connection smoother, thereby greatly reducing water loss. At the same time, the structural setting can also play a buffering role on the passing water flow, further reducing water loss and greatly improving the practicality of the PPR pipe fittings.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.
[0030] See also Figure 1-4 , the present application provides a technical solution: a low water loss PPR pipe fitting, comprising a connecting pipe fitting 1, a connecting end head 2 is fixed on the outer side of the end of the connecting pipe fitting 1, a transition assembly 300 for reducing water loss is installed on the inner side of the connecting pipe fitting 1, and a plurality of anti-slip strips 4 are fixedly connected to the outer side of the connecting pipe fitting 1 and the outer side of the connecting end head 2;
[0031] By using the connecting pipe 1, the connecting end 2 and the internal transition component 300, the liquid after hot melting has a certain flow space, so that the molten PPR can be gathered inside the space, thereby avoiding the formation of an annular blocking structure on the inside, making the inside of the pipe after hot melting connection smoother, thereby greatly reducing water loss. At the same time, the structural setting can also play a buffering role on the passing water flow, further reducing water loss and greatly improving the practicality of the PPR pipe fittings.
[0032] like Figure 4 As shown, it should be noted that the number of anti-slip strips 4 is seven, and three anti-slip strips 4 are fixed on the outside of the connecting end 2, the anti-slip strips 4 are in the shape of long strips, and there are four anti-slip strips 4 on the outside of the connecting pipe 1 away from the connecting end 2, and the four anti-slip strips 4 on the outside of the connecting pipe 1 away from the connecting end 2 are distributed in a circle, so that the anti-slip strips 4 can facilitate the operator to hold the end of the connecting pipe 1 or the end of the connecting end 2, wherein the connecting pipe 1, the connecting end 2, the transition assembly 300 and the anti-slip strips 4 are all made of PPR material in one piece.
[0033] In this embodiment, the transition assembly 300 is a structure for reducing water loss and allowing the water flowing inside to be transported stably.
[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the transition assembly 300 includes an annular transition block 301 fixed to the inner side of the connecting pipe 1 away from the end of the connecting terminal 2, a first fillet 302 opened between the outer side of the annular transition block 301 away from the connecting terminal 2 and the inner side of the connecting pipe 1, an annular bevel block 303 fixed to the inner side of the connecting pipe 1 close to the end of the connecting terminal 2, and a second fillet 304 opened between the outer side of the annular bevel block 303 close to the connecting terminal 2 and the inner side of the connecting pipe 1.
[0035] It should be noted that the interior of the annular transition block 301 is connected with the interior of the annular bevel block 303, and the annular transition block 301 and the annular bevel block 303 are connected to form a tubular structure. The connecting pipe fitting 1 is L-shaped, and the tubular structure formed by the annular transition block 301 and the annular bevel block 303 is located at the inner curved part of the connecting pipe fitting 1. The two ends of the tubular structure formed by the annular transition block 301 and the annular bevel block 303 extend to the two ends of the inside of the connecting pipe fitting 1 respectively, so that the water flowing inside can be normally transported on the inner wall of the tubular structure formed by the annular transition block 301 and the annular bevel block 303.
[0036] In addition, the side of the annular bevel block 303 away from the curved portion of the connecting pipe fitting 1 is a bevel, and the bevel of the annular bevel block 303 is inclined toward the side close to the curved portion of the connecting pipe fitting 1, so that the inclined bevel can facilitate the passage of water and can buffer the water flow, so that it can remain stable, thereby further reducing water loss. The inner diameter of the annular bevel block 303 is equal to the inner diameter of the annular transition block 301, so that the internal water flow can be transported normally.
[0037] It should also be noted that, under the action of the second fillet 304, the end of the pipe fitting for connection can be abutted, so that a space that can accommodate the molten PPR material is formed between the end of the pipe fitting for connection and the bevel of the annular bevel block 303. The PPR connection part cooled and formed inside the space has less obstruction to the water flow. Under the action of the first fillet 302, the connection between the annular transition block 301 and the connecting pipe fitting 1 can be kept beautiful, and the passing water can also be smoothly transported.
[0038] The working principle of the above embodiment is:
[0039] When hot-melt connection is performed, the pipe fitting used for connection is inserted into the connecting pipe fitting 1 near the side of the connecting end 2, so that the end of the pipe fitting used for connection abuts against the second fillet 304, so that a circle of triangular accommodating space is formed between the annular bevel block 303 and the end of the connected pipe fitting, so that the molten PPR can be gathered inside the space and then cooled and solidified, thereby greatly reducing the obstruction of the connecting part to the water flow. At the same time, under the action of the bevel of the annular bevel block 303, the incoming water flow can have a buffer space, so that the water flow can be transported smoothly and stably, and after passing through the annular transition block 301, it enters the other end of the connecting pipe fitting 1, so that the water flow flowing inside the connecting pipe fitting 1 can be transported with low water loss.
[0040] Compared with the prior art, the low water loss PPR pipe fitting, through the use of connecting pipe fittings 1, connecting ends 2 and internal transition components 300, allows the liquid after hot melting to have a certain flow space, so that the molten PPR can be gathered inside the space, thereby avoiding the formation of an annular blocking structure on the inside, making the inside of the pipe fitting after hot melting connection smoother, thereby greatly reducing water loss. At the same time, the structure can also buffer the passing water flow, further reducing water loss, and greatly improving the practicality of the PPR pipe fittings, solving the problem that the existing PPR pipe fittings are not smooth enough after hot melting connection, resulting in obstruction of the flowing liquid and causing greater water loss.
