[0040] The specific embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0041] In this document, "upper", "lower", "front", "rear", "left", "right", and the like are used to describe relative positions between relevant parts, and do not limit the absolute positions of the relevant parts.

[0042] In this document, "first", "second", and the like are used to distinguish between each other, and do not indicate importance and order, and are not a prerequisite for each other.

[0043] In this document, "equal", "same", and the like are not strictly limited in the mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and allowed in manufacturing or use, etc.

[0044] In order to solve the connection problem between the granite composite material pipe fitting and the target pipe made of other materials, the present disclosure provides a pipe fitting connecting device. The pipe fitting connecting device is used to connect the granite composite material pipe 1 and the target pipe 2 made of non-granite composite material, and specifically includes a granite composite material sleeve 3, a target sleeve 4, a first flange 5, a second flange 6, and a connecting mechanism 7.

[0045] As Figure 1 , Figure 2As shown in the figure, the basalt composite sleeve 3 is configured to be sleeved on the basalt composite pipe 1 and has a radially extending first annular flange 31; the target sleeve 4 is configured to be sleeved on the target pipe 2 and has a radially extending second annular flange 41; the first flange 5 is sleeved on the basalt composite sleeve 3 and abuts against the first annular flange 31; the second flange 6 is sleeved on the target sleeve 4 and abuts against the second annular flange 41; the connecting mechanism 7 is configured to drive the first flange 5 and the second flange 6 to move towards each other until the first annular flange 31 and the second annular flange 41 are tightly sealed.

[0046] Specifically, in combination with Figure 3 、 Figure 4 , in actual application, first, the target sleeve and the target pipe, and the basalt composite pipe and the basalt composite sleeve are pre-connected.

[0047] Specifically, the pre-connection manner of the basalt composite pipe and the basalt composite sleeve is that the basalt composite sleeve 3 is sleeved on the connecting end of the basalt composite pipe 1 first, and then the basalt composite pipe 1 and the basalt composite sleeve 3 are fixed relative to each other.

[0048] It should be noted that due to the particularity of the basalt composite pipe, the conventional welding or hot melting cannot be used to realize the fixed connection of the basalt composite pipe and the basalt composite sleeve, therefore, in an embodiment, an organic adhesive is used to realize the fixed connection of the two, in detail, the organic adhesive is filled into the circumferential gap between the basalt composite pipe and the basalt composite sleeve until the organic adhesive solidifies.

[0049] The pre-connection manner of the target sleeve and the target pipe depends on the specific material, for example, in an embodiment, the target pipe is a PE pipe and the target sleeve is a PE sleeve, the target pipe and the target sleeve can be fixedly connected by hot melting, that is, the opposite ends of the target pipe and the target sleeve are heated to melt, and then butted and adhered to cool.

[0050] For another example, in an embodiment, the target pipe is a metal pipe and the target sleeve is a metal sleeve, the opposite ends of the two are butted and directly welded to be fixed together during connection. Of course, the target sleeve and the target pipe can also have different pipe diameters, the target pipe is inserted into the target sleeve after the end of the target sleeve is heated and expanded, and the target sleeve is fixedly connected with the target pipe after cooling due to thermal expansion and cold contraction.

[0051] It should be noted that the target pipe and the target sleeve in the present disclosure can be made of the same material, such as both made of PE or metal, and of course the target pipe and the target sleeve can also be made of two different materials, such as the target pipe being a metal pipe and the target sleeve being a PE pipe, and those skilled in the art can select appropriate pipe fittings according to actual needs.

[0052] As described above, the first flange is sleeved on the stone composite sleeve and abuts against the first flange on the stone composite sleeve, and the installation time node of the first flange can be arranged before or after the pre-connection of the stone composite pipe and the stone composite sleeve.

[0053] Specifically, in one embodiment, the first flange is sleeved on the stone composite sleeve first, and then the pre-connection of the stone composite sleeve and the stone composite pipe is completed. It can be understood that this connection mode is more suitable for the case that the stone composite pipe is relatively long, and the staff can complete the preliminary installation among the stone composite pipe, the stone composite sleeve and the first flange at the same installation point.

[0054] In another embodiment, the staff can first complete the pre-connection of the stone composite pipe and the stone composite sleeve, and then sleeve the first flange on the stone composite pipe through the other end of the stone composite pipe and move it to abut against the first flange.

[0055] It can be understood that the installation mode of the target pipe, the target sleeve and the second flange can refer to the installation mode of the stone composite pipe, the stone composite sleeve and the first flange as described above, which will not be described herein.

[0056] Continuing to refer to Figure 3 and Figure 4 , after the target pipe, the stone composite pipe and the respective corresponding sleeve and flange are connected, the first flange 5 and the second flange 6 are pushed towards each other by the connecting mechanism, and the first annular flange 31 and the second annular flange 41 are sealed and abutted, thus perfectly realizing the connection between the stone composite pipe and the target pipe made of non-stone composite material, and the structure is simple and the connection is reliable and stable. Users can select appropriate target pipes and stone composite pipes for connection according to actual scene needs, such as replacing the road water pipe for bearing larger pressure in the urban water supply pipeline system with a stone composite pipe, and using a PE pipe for the underground water pipe bearing smaller pressure.

[0057] In one embodiment of the present disclosure, the pipe connection device comprises a plurality of connecting mechanisms 7, which are sequentially and spaced apart along the circumference of the first flange 5 and the second flange 6.

[0058] As Figure 1 ,Figure 2 As shown, the plurality of connecting mechanisms 7 are evenly arranged around the periphery of the first flange 5 and the second flange 6, and thus arranged, the stress on the first flange 5 and the second flange 6 is more uniform, and the first annular flange 31 and the second annular flange 41 are more closely attached, thereby ensuring the sealing of the pipe connection.

[0059] In one embodiment, the connecting mechanism comprises a matched fastening bolt 71 and nut 72, the fastening bolt 71 penetrates the first flange 5 and the second flange 6 and cooperates with the nut 72 to move the first flange 5 and the second flange 6 towards each other.

[0060] In detail, as shown in the drawings, Figure 4 The connecting mechanism 7 is specifically a plurality of fastening bolts 71 and nuts 72, the first flange 5 and the second flange 6 are evenly provided with through holes in the circumferential direction, the fastening bolts 71 penetrate the through holes of the first flange 5 and the second flange 6 and cooperate with the nuts 72 to fasten the first flange 5 and the second flange 6.

[0061] In one embodiment, as shown in the drawings, Figure 5 , Figure 6 The connecting structure comprises a first operating rod 73 and a second operating rod 74. One end of the first operating rod 73 is hinged to the first flange 5, one end of the second operating rod 74 is hinged to the middle of the first operating rod 73, and the other end has a hook, the second flange 6 is provided with a clamping groove 61 on the end face away from the first flange 5, and the first operating rod 73 is configured to rotate relative to the first flange 5 to drive the hook of the second operating rod 74 to be clamped into the clamping groove 61 of the second flange, and the intersection point of the first operating rod 73 and the first flange 5 and the hinge point of the first operating rod 73 and the second operating rod 74 reach the rotation dead point position, thereby clamping the first annular flange 31 and the second annular flange 41 to completely attach.

[0062] The two connecting mechanisms 7 provided by the present disclosure have simple structure and strong connection stability, effectively ensuring the close attachment of the first annular flange 31 and the second annular flange 41. Of course, in actual application, users can select appropriate connecting mechanisms 7 according to the scene needs, which will not be described here.

[0063] Continuing to refer to Figure 2 , Figure 4 In one embodiment, the pipe connection device of the present disclosure further comprises a sealing ring 8 between the first annular flange 31 and the second annular flange 41, thereby ensuring the sealing requirement of the stone composite material pipe 1 and the target pipe 2.

[0064] In one embodiment of the present disclosure, the end face of the first annular flange 31 and / or the second annular flange 41 is provided with a sealing groove, and the sealing groove is configured to place the sealing ring 8.

[0065] Specifically, in the pipe fitting connection device provided in this disclosure, a sealing groove is provided on the first annular flange 31, or a sealing groove is provided on the second annular flange 41. In both cases, the depth of the sealing groove is less than the thickness of the sealing ring 8. During the process of the first annular flange 31 and the second annular flange 41 fitting together, the sealing ring 8 is compressed to achieve the sealing between the first annular flange 31 and the second annular flange 41.

[0066] In another scenario, both the first annular flange 31 and the second annular flange 41 can be provided with sealing grooves. In this case, the sum of the depths of the sealing grooves of the first annular flange 31 and the second annular flange 41 is less than the thickness of the sealing ring 8. Similarly, during the process of the first annular flange 31 and the second annular flange 41 fitting together, the sealing ring 8 is compressed to achieve the seal between the first annular flange 31 and the second annular flange 41.

[0067] In one embodiment of this disclosure, both the basalt composite material pipe 1 and the target pipe 2 are water pipes. In practical applications, the basalt composite material pipe 1 provided in this disclosure is mainly used as a road-crossing water pipe, that is, a water pipe laid under the road surface, to cope with high pressure and high temperature conditions. In non-road areas, since the pressure on the pipes is relatively small, other and more economical target pipes 2 are used as connecting water pipes.

[0068] Secondly, this disclosure also provides a piping system comprising a basalt composite material pipe 1, a target pipe 2 made of a non-basalt composite material, and the aforementioned pipe fitting connection device.

[0069] Specifically, the pipeline system provided in this disclosure is composed of multiple basalt composite material pipes 1 and target pipes 2 made of non-basalt composite material, wherein the connecting device is the pipe fitting connecting device mentioned above.

[0070] The pipeline system connects the basalt composite pipe 1 to the target pipe 2, which is made of non-basalt composite material, through a pipe fitting connection device, enabling the laying of pipe fittings for different road conditions. Simultaneously, the pipeline system includes pipe fittings of different materials, allowing for the installation and connection of appropriate fittings in various situations.

[0071] To facilitate a better understanding of the piping system disclosed herein, an application scenario will be used as an example.

[0072] like Figure 7 As shown, the above-mentioned pipeline system is laid under the road surface. Specifically, a black stone composite material pipe 1 is installed 1.5m directly below the road surface, and target pipes 2 made of non-black stone composite material are installed underground on both sides of the road surface. The black stone composite material pipe 1 and the target pipe 2 are connected by the above-mentioned pipe fitting connection device.

[0073] When two trucks with a load of 60 tons pass on the road surface at the same time, if the pipeline installed under the road surface is made of PE material, the pipeline will be deformed due to too much pressure. If the pipeline system spliced by the basalt composite pipe and the PE pipe in the present disclosure is replaced, the compression resistance of the pipeline under the road surface can be improved, the normal and reliable work of the pipeline can be ensured, the original pipeline under the road surface of the non-transportation road surface in the original pipeline can be reserved, only the PE pipe under the road surface of the transportation road surface in the original pipeline needs to be replaced by the basalt composite pipe, and the two are sealed and spliced through the pipe joint connecting device of the present disclosure, so that the difficulty of the original pipeline reconstruction is reduced.

[0074] The above has described various embodiments of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles, practical application or technical improvement in the market of the embodiments, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
