[0048] In order to better explain the present application, so as to be understood, the following specific embodiments are combined with the drawings, and the present application is described in detail. In this paper, the orientation of "up", "down", "left", "right", "front" and "back" and other orientation terms are taken as the reference of the drawings. Figure 1

[0049] Referring to Figures 1-4 As shown in the drawings, the embodiment of the present application proposes a pipeline assembly with a water supply and drainage valve, which comprises a water supply and drainage valve, two connecting pipes 2 respectively connected to the left and right ends of the water supply and drainage valve, and two fixing assemblies 3 and two sealing units 6 for respectively fixing and installing the connecting pipes 2 on the two ends of the water supply and drainage valve.

[0050] ​The water supply and drainage valve comprises a valve body 1 and two extension parts 5 respectively protruding outward from both sides of the valve body 1. The valve body 1 is provided with a valve cavity 4, and the left and right end faces of the valve body 1 are respectively provided with the extension part 5 outwardly protruding. Each extension part 5 is provided with a communication pipeline, one end of the communication pipeline being in communication with the valve cavity 4.

[0051] Further, the valve body 1 comprises a valve frame 11, a valve core 12, a valve rod 13 and a hand wheel 14.

[0052] The space enclosed by the valve frame 11 constitutes the valve cavity 4, the valve core 12 is arranged in the valve cavity 4, one end of the valve rod 13 is connected with the valve core 12, and the other end of the valve rod 13 extends outward through the top of the valve frame 11 and is connected with the hand wheel 14.

[0053] Rotating the hand wheel 14 drives the valve core 12 to rotate relative to the valve cavity 4 through the valve rod 13 to adjust the water flow of the water supply and drainage valve.

[0054] Further, an adjusting seat 7 is arranged coaxially with the valve rod 13 on the outside of the valve rod 13, and a dynamic sealing ring is arranged between the adjusting seat 7 and the valve rod 13.

[0055] Specifically, a rotating groove is formed in the top end face of the hand wheel 3. The rotating groove is cross-shaped, which is convenient for workers to insert a cross-shaped tool into the rotating groove to rotate the hand wheel 3 to adjust the valve core 12.

[0056] Further, waterproof outer rings are sleeved on the left and right sides of the valve core 12, and waterproof sealing strips are further arranged on the inner side walls of the waterproof outer rings and the outer side walls of the valve core 12.

[0057] In this embodiment, two waterproof outer rings and two sealing strips are arranged on the valve core 12, and a dynamic sealing ring is arranged between the adjusting seat 7 and the valve rod 13. The dynamic sealing ring is arranged to enhance the waterproof sealing effect between the valve rod 13 and the valve core 12. The water flow on both sides of the valve body 1 is adjusted by rotating the valve core 12 through the hand wheel 3. Moreover, when the waterproof outer ring and the sealing strip on one side of the valve core 12 are damaged, the waterproof outer ring and the sealing strip on the other side can continuously seal the valve body 1, so as to avoid the valve body 1 from leaking sewage and improve the use effect and stability of the valve body 1.

[0058] Further, the valve frame 11 comprises a cylindrical side wall 111, a first end face 112 and a second end face 113.

[0059] The two extension parts 5 are respectively located on the first end face 112 and the second end face 113. The cylindrical side wall 111 and the outer side walls of the two extension parts 5 form annular stepped end faces at the corresponding first end face 112 and second end face 113.

[0060] It should be noted that the purpose of the annular stepped end face is to better connect the pipe 2, that is, the annular stepped end face can be appropriately spread outward in the radial direction by a certain size to enhance the contact surface of the valve body 1 and the connecting pipe 2, more convenient to install and disassemble, while improving the connection effect of the valve body 1 and the connecting pipe 2, making the connection more stable. Therefore, referring to Figures 1-2 It can be seen that in the embodiment, the width of the first end face 112 and the second end face 113 is greater than that of the cylindrical side wall 111, which is to increase the contact area of the valve body 1 and the connecting pipe 2.

[0061] One end of the two connecting pipes 2 is respectively sleeved outside the extension part 5, and is detachably connected through a fixing assembly 3, and the other end of the connecting pipe 2 can be integrally formed with the pipeline and connected as a part of the pipeline to form an overall drainage system.

[0062] Further, the connecting pipe 2 comprises a connecting pipe body 21 and an annular connecting piece 22 arranged at the end of the connecting pipe body 21 (the end refers to the end close to the first end face 111 or the second end face 112 of the valve body 1).

[0063] One side end face of the annular connecting piece 22 abuts against the annular stepped end face and is fixed by the fixing assembly 3.

[0064] Further, the fixing assembly 3 comprises a first fixing unit 31.

[0065] The first fixing unit 31 comprises a plurality of positioning pins 311 arranged on the annular stepped end face at equal intervals along the circumferential side wall of the annular stepped end face.

[0066] The annular connecting piece 22 is provided with a plurality of positioning through holes 221 corresponding to the plurality of positioning pins 311, and the positioning pins 311 pass through the positioning through holes 221 and are clamped with the annular connecting piece 22.

[0067] Further, the positioning pins 311 are clamped with the positioning through holes 221 through a clamping assembly 8. Specifically, the clamping assembly 8 can be a clamping slot 82 provided on the positioning pin 311 and a clamping block 81 provided on the positioning through hole 221, which can realize quick disassembly and fixing through clamping.

[0068] Further, the fixing assembly 3 further comprises a second fixing unit 32.

[0069] The second fixing unit 32 comprises a plurality of clamping mechanisms 321 arranged on the connecting pipe body 21 at equal intervals, and the clamping mechanisms 321 can move towards or away from the outer side wall of the extension part 5 along the radial direction of the connecting pipe body 21 to clamp or loosen the extension part 5.

[0070] It should be noted that the clamping mechanism 321 can achieve better connection effect, prevent the connection pipe body 21 from moving in the axial direction or the proceeding direction relative to the extension part 5, and further ensure the stability between the connection pipe 2 and the extension part 5.

[0071] Further, the clamping mechanism 321 comprises a clamping plate 3211, a screw rod 3212 and an adjusting handle 3213.

[0073] Specifically, the clamping plate 3211 is in an arc structure. A plurality of clamping plates 3211 are uniformly arranged at intervals along the circumferential outer side wall of the connection pipe body 21.

[0074] The outer wall of the connection pipe body 21 is provided with a threaded hole 211 for the screw rod 3212 to pass through and be fixed, and the threaded hole 211 is also uniformly arranged at intervals along the circumferential outer side wall of the connection pipe body 21 and is correspondingly arranged with the clamping plate 3211.

[0075] When the clamping plate 3211 moves along the radial direction of the connection pipe body 21 towards the outer side wall of the extension part 5, the inner side wall of the clamping plate 3211 abuts against the outer side wall of the extension part 5.

[0076] Specifically, the inner side wall of the clamping plate 3211 is also provided with a non-slip pad, which plays a role in increasing friction.

[0077] It should be noted that a fixed groove 51 is arranged on the outer side wall of the extension part 5 corresponding to the clamping plate 3211, which can make the clamping effect of the clamping plate 3211 better, and also play a role in axial positioning.

[0078] Further, a receiving groove is arranged on the inner side wall of the connection pipe body 21 corresponding to the clamping plate 3211, which is used to accommodate the clamping plate 3211. It should be noted that when the clamping plate is not used, the clamping plate 3211 is fixedly arranged in the receiving groove by screwing the screw rod 3212 and the threaded hole 211. This facilitates the smooth connection of the extension part 5 and the connection pipe 2, and does not affect the connection of the two.

[0079] Further, a clamping ring 3214 is also sleeved at the position of the outer circle of the connection pipe body 21 corresponding to the clamping plate 3211, and the clamping ring 3214 is arranged to have a threaded hole corresponding to the threaded hole 211 on the clamping ring 3214, which improves the screwing area of the screw rod 3212 and enhances the stability.

[0080] One of the sealing units 6 is arranged between each of the two connecting pipes 2 and the corresponding extension 5.

[0081] Further, the sealing unit 6 comprises a first sealing member 61.

[0082] The first sealing member 61 is arranged on the circumferential outer side wall of the extension 5 away from the valve body 1, and an annular groove is formed on the circumferential outer side wall of the extension 5, the first sealing member 61 is arranged in the annular groove, the inner side wall of the first sealing member 61 abuts against the annular groove, and the outer side wall of the first sealing member 61 abuts against the inner side wall of the connecting pipe body 21, so as to prevent sewage from flowing back.

[0083] Specifically, the first sealing member 61 is an annular sealing ring.

[0084] Further, the sealing unit 6 further comprises a second sealing member 62 arranged in the connecting pipe body 21, the connecting pipe body 21 is integrally formed with an annular boss 23 inwardly in the radial direction, one side end surface of the second sealing member 62 abuts against the annular boss 23, and the other side end surface of the second sealing member 62 abuts against the end surface of the extension 5 away from the valve body 1.
