Description

Technical Field

[0001] The utility model relates to the field of valve cutoff, in particular to a multi-way valve docking structure. Background Art

[0002] Multi-way valves play an important role in distributing, regulating, and shutting off medium flow in fluid control systems. However, leakage often occurs at the interface between the multi-way valve and the oil pipe, which seriously affects the performance and reliability of the system.

[0003] Currently, the traditional method of fixing oil pipes is to apply glue after fixing the oil pipe ends to the multi-way valve. This method requires glue removal during subsequent maintenance, which is cumbersome and inefficient. At the same time, during maintenance, due to space limitations, it is impossible to visually observe the degree of aging of the glue, and thus it is impossible to judge the tightness of the connection between the oil pipe and the multi-way valve. Utility Model Content

[0004] The utility model aims to provide a multi-way valve docking structure with the oil pipe not easily falling off and relatively stable structure.

[0005] The purpose of the utility model is achieved as follows: a multi-way valve docking structure, including a valve body and an oil pipe;

[0006] An oil inlet group and an oil outlet group are provided on the top of the valve body. The oil inlet group and the oil outlet group are arranged side by side. Both the oil inlet group and the oil outlet group are composed of a plurality of oil ports. A fixed cylinder is provided extending outward from the periphery of the oil port, and a rotating ring is provided on the periphery of the fixed cylinder. A rotating ring protrusion is provided on the rotating ring, and a lower through hole is provided on the rotating ring protrusion.

[0007] The oil pipe consists of a butt end and a pipe body; a limit ring is provided at the connection between the butt end and the pipe body, a limit ring protrusion block is provided on the limit ring, an upper through hole is provided on the limit ring protrusion block, and the limit ring is connected to the rotating ring by bolts passing through the upper through hole and the lower through hole.

[0008] Preferably, the outer wall of the docking end and the inner wall of the fixed tube are both provided with right-hand threads, and the inner wall of the rotating ring and the outer wall of the fixed tube are both provided with left-hand threads.

[0009] Preferably, the upper through hole and the lower through hole are of the same size and the inner walls thereof are both provided with internal threads.

[0010] Preferably, after the rotating ring rotates around the fixed cylinder for one circle, the rotating ring body is still placed on the outer wall of the fixed cylinder without being separated.

[0011] Preferably, after the butt joint end is butted against the fixing tube, the limiting ring contacts the top of the fixing tube.

[0012] Preferably, the distance between adjacent oil ports is greater than twice the maximum distance from the center of the rotating ring to the outer edge of the protruding block of the rotating ring.

[0013] Compared with the prior art, the present invention is beneficial in that:

[0014] 1. After the oil pipe and the oil port are rotated and docked, the limit ring can be connected to the rotating ring protrusion below by bolts. Since the thread rotation direction of the inner wall of the rotating ring is opposite to that of the inner wall of the fixed cylinder, the oil pipe can be fixed after the bolts are connected to prevent it from rotating and falling off.

[0015] 2. Set a thread on the outer wall of the fixed tube and ensure that the height of the fixed tube can realize the rotation of the rotating ring. Finally, it is ensured that after the oil pipe is docked, no matter what direction the limit ring is in, the rotating ring can be adjusted to dock with it to achieve fixation.

[0018] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0019] It should be noted that in the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the utility model product is usually placed when in use. These are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance. Terms such as "horizontal", "vertical", and "overhanging" do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, indirect connections via an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0021] like Figure 1 As shown, a multi-way valve docking structure includes a valve body 1 and an oil pipe 2;

[0022] An oil inlet group 3 and an oil outlet group 4 are provided at the top of the valve body 1. The oil inlet group 3 and the oil outlet group 4 are arranged side by side. Each of the oil inlet group 3 and the oil outlet group 4 is composed of a plurality of oil ports 5. A fixed cylinder 6 is provided extending outward from the periphery of the oil ports 5. A rotating ring 7 is provided on the periphery of the fixed cylinder 6. A rotating ring protrusion 701 is provided on the rotating ring protrusion 701. A lower through hole 7011 is provided on the rotating ring protrusion 701.

[0023] like Figure 1 As shown, the oil pipe 2 consists of a butt end 201 and a pipe body 202; a limit ring 8 is provided at the connection between the butt end 201 and the pipe body 202, and a limit ring protrusion 801 is provided on the limit ring 8, and an upper through hole 8011 is provided on the limit ring protrusion 801. The limit ring 8 is connected to the rotating ring 7 by a bolt 9 passing through the upper through hole 8011 and the lower through hole 7011.

[0024] like Figure 1 As shown, the outer wall of the docking end 201 and the inner wall of the fixed tube 6 are both set to right-hand threads, and the inner wall of the rotating ring 7 and the outer wall of the fixed tube 6 are both set to left-hand threads. After the limit ring and the rotating protrusion block are connected by bolts, the opposite inner and outer threads will interfere with each other to ensure that the oil pipe will not rotate.

[0025] like Figure 1 As shown, the upper through hole 8011 and the lower through hole 7011 are of the same size and have internal threads on their inner walls, and the distance between their centers and the center of the oil port is consistent, so that the bolts can be inserted and fixed after the upper and lower through holes correspond to each other.

[0026] like Figure 1 As shown, after the rotating ring 7 rotates around the fixed cylinder 6 for one circle, the main body of the rotating ring 7 is still placed on the outer wall of the fixed cylinder 6 and does not separate, ensuring that the rotating main body can rotate 360°, that is, the lower through hole on the protruding block of the rotating ring can correspond to the upper through hole on the limiting ring.

[0027] like Figure 1As shown, after the docking end 201 is docked with the fixed tube 6, the limiting ring 8 contacts the top of the fixed tube 6. After the limiting ring contacts, it can ensure that the rotating ring will not rotate out of the outer wall of the fixed tube, so that it is always placed on the fixed tube, and the stability is higher after being connected with the limiting ring.

[0028] like Figure 1 As shown, the spacing between adjacent oil ports 5 is greater than twice the maximum spacing from the center of the rotating ring 7 to the outer edge of the rotating ring protrusion 701, ensuring that each group of rotating rings will not conflict with each other during rotation, and can achieve a complete circular rotation, that is, it can correspond to the through hole of the upper limit ring, further realizing bolt fixation.

[0029] The working principle of the present invention is explained as follows: when in use, first rotate the docking end and the fixed cylinder to dock them, and multiple sets of sealing rings can be set between the docking end and the fixed cylinder to enhance the sealing, then rotate the rotating ring at the bottom, match the rotating ring protrusion block with the upper limit ring protrusion block, and tighten and fix it with bolts; the oil pipe is limited by the restriction of the positive and negative threads to prevent it from rotating on its own, and it also avoids the use of glue and other tools to fix it, which is convenient for subsequent maintenance; and during maintenance, the obvious feature of whether the bolts are falling off can be observed. If they are falling off, they need to be fixed with bolts. If they are not falling off, it means that the oil pipe and the valve body have not rotated on their own.

[0030] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
