Detailed Description

The following describes the structural and operational principles of the present invention in detail with reference to the accompanying drawings:

referring to fig. 1 and fig. 2, fig. 1 is a schematic perspective view of an embodiment of a bifurcation valve structure of the present invention, and fig. 2 is a schematic cross-sectional view taken along the section line 2-2 in fig. 1. The split valve structure illustrated in fig. 1 and 2 includes a valve seat 10, a ball plunger 20, a plurality of disassembled sections 30, and a plurality of pipe connection sections 40. The ball plug 20 is disposed in the valve seat 10, and the valve seat 10 is connected to the disassembly section 30 and then connected to the pipeline connection section 40. The external piping is then connected to the piping connection segment 40. Accordingly, the disassembly section 30 and the pipeline connection section 40 between the valve seat 10 and the external pipeline can be disassembled respectively.

In one embodiment, the valve seat 10 is a hollow structure and has a seat body 11 and a branch pipe portion 12. The seat body 11 is hollow and has an accommodating space 111, and the branch pipe portion 12 is a hollow pipe body and is communicated with the accommodating space 111 of the seat body 11. In a specific embodiment, the valve seat 10 has a circular outer peripheral surface, the number of the branch pipe portions 12 is three, and each branch pipe portion 12 is located at an equiangular position of the outer peripheral surface of the valve seat 10. In this embodiment, one of the manifold portions 12 may be used as a fluid inlet, and the other two manifold portions 12 may be used as a fluid outlet, but the present invention is not limited thereto, and the number of the manifold portions 12 and the direction of the fluid may be set according to the requirement.

Each of the manifold portions 12 has one end connected to the housing 11 and the other end having a first flange portion 121. The first flange portion 121 has an outer diameter greater than the outer diameter of the manifold portion 12 to facilitate connection of the disassembled section 30.

Referring to fig. 2, the ball plunger 20 has a hollow spherical structure whose external shape roughly corresponds to the shape of the accommodating space 111 of the seat body 11 of the valve seat 10. Specifically, the ball plug 20 is rotatably received in the receiving space 111 of the seat body 11 of the valve seat 10 and has a plurality of flow channels 21 for turning to communicate with different manifold portions 12 to control the flow direction of the fluid, and the specific structure of the ball plug 20 is the prior art in this field and will not be described herein.

Referring to fig. 1 to 4, fig. 3 is a partially enlarged view of circled portion 3 of fig. 2; fig. 4 is a schematic exploded view of a plane structure of an embodiment of the present invention. In one embodiment, the manifold valve structure comprises a number of disassembled sections 30 corresponding to the number of manifold portions 12, each disassembled section 30 being detachably connected to each manifold portion 12 of the valve seat 10. Specifically, the disassembled section 30 is a hollow pipe structure and has an inner embedded section 31 and a second flange portion 32, which are connected to each other, and the outer diameter of the second flange portion 32 is larger than the outer diameter of the inner block 31 for connecting with the pipe connecting section 40. In this embodiment, the embedded section 31 of the disassembled section 30 penetrates into the branch pipe portion 12 of the valve seat 10, and the second flange portion 32 is connected to the first flange portion 121.

In one embodiment, the manifold portion 12 has an inner manifold surface 122, and the inner insert section 31 of the disassembled section 30 has an outer embedded tube surface 311 and an inner embedded tube surface 312 opposite to each other. In this embodiment, the disassembled section 30 is inserted into the branch pipe portion 12 of the valve seat 10 in a direction from the embedded pipe outer surface 311 toward the branch pipe inner surface 122, so that the disassembled section 30 is assembled in an embedded manner, and only the second flange portion 32 for connecting the pipeline connecting section 40 is exposed, thereby increasing the structural stability of the disassembled section 30.

Referring to fig. 2 and 3, in an embodiment, the pipeline connecting section 40 is used for connecting external pipelines. Specifically, the pipe connection section 40 is a hollow pipe structure and has a third flange portion 41, a pipe 42 and a fourth flange portion 43 which are sequentially connected. In this embodiment, the outer diameters of the third flange portion 41 and the fourth flange portion 43 are respectively larger than the outer diameter of the pipe 42 to facilitate connection with the second flange portion 32 or the external pipe. Here, the pipe connecting section 40 is connected to the second flange portion 32 of the dismantling section 30 by the third flange portion 41.

In one embodiment, the pipe 42 of the pipe connecting section 40 has an inner pipe surface 421 and an outer pipe surface 422. When the pipe connecting section 40 is connected to the disassembled section 30, the inner surface 421 of the pipe connecting section 40 is coplanar with the inner surface 312 of the embedded pipe of the disassembled section 30. That is, when the pipe connecting section 40 is connected to the disassembled section 30, there is no step difference between the inner pipe surface 421 of the pipe connecting section 40 and the inner embedded pipe surface 312 of the disassembled section 30.

Therefore, when a maintenance worker wants to maintain the branching valve structure, the disassembly section 30 and the pipeline connection section 40 can be respectively disassembled between the external connecting pipeline and the valve seat 10, so that the difficulty of disassembly and maintenance can be reduced, and the working efficiency of the maintenance worker can be improved. In addition, because the structure between the valve seat 10 and the external pipeline can be disassembled, when the valve seat needs to be disassembled for maintenance, the valve seat does not need to use large-scale machines or the assistance of a crane, and the cost of the maintenance work can be further reduced.

Referring to fig. 2 and 3, in one embodiment, the valve seat 10 and the disassembled section 30 are connected by a plurality of first connecting members 50. Specifically, the first connector 50 may be, but is not limited to, a screw lock. In this embodiment, the first connector 50 passes from the second flange portion 32 of the disassembled section 30 to the first flange portion 121 of the valve seat 10 to lock the valve seat 10 and the disassembled section 30, and the first connector 50 does not protrude from the surface of the second flange portion 32 facing the third flange portion 41.

Referring to fig. 2 and 3, in one embodiment, the disassembled section 30 is connected to the pipeline connecting portion 40 by a second connecting member 60. Specifically, the second connector 60 may be, but is not limited to, a screw lock. In this embodiment, the second connector 60 is threaded from the third flange portion 41 of the pipe connecting section 40 to the first flange portion 121 of the valve seat 10 through the second flange portion 32 of the disassembled section 30 to lock the pipe connecting section 40, the disassembled section 30, and the valve seat 10.

When the disassembled sections 30 are assembled on the valve seat 10 and extend into the receiving space 111, the ball plug 20 is rotated to connect the ball plug 20 with the different disassembled sections 30 through the different flow passages 21, and when the flow passage 21 of the ball plug 20 is connected with the disassembled sections 30, the first sealing member 70 can be located on the outer periphery of the flow passage 21 of the ball plug 20, so that the leakage-proof effect is provided between the disassembled sections 30 and the flow passages 21 of the ball plug 20. Specifically, the first seal 70 may be, but is not limited to, an annular structure made of rubber.

With continued reference to fig. 2 and 3, in one embodiment, a second sealing element 80 may be further disposed between the first flange portion 121 of each valve seat 10 and the second flange portion 32 of each disassembled section 30. Specifically, the inner peripheral surface of the first flange portion 121 of the valve seat 10 adjacent to the inner surface 122 of the branch pipe has a second ring groove 123, and the second seal 80 is received in the second ring groove 123. When the disassembled section 30 is connected to the valve seat 10, the second flange portion 32 of the disassembled section 30 abuts against the second sealing member 80, so that the valve seat 10 and the disassembled section 30 are leakproof. Here, the second sealing member 80 may be, but is not limited to, a ring structure made of rubber.

Referring to fig. 2 and 3, in an embodiment, third sealing members 90 may be further disposed between the second flange portion 32 of each disassembled section 30 and the third flange portion 41 of each pipeline connecting section 40. Specifically, the third flange portion 41 of each pipe connecting section 40 has a third ring groove 411 on a face thereof facing the second flange portion 32, and the third seal 90 is received in the third ring groove 411. When the pipe connecting section 40 is connected to the disassembling section 30, the second flange portion 32 of the disassembling section 30 abuts against the third sealing member 90, so that the leakage-proof effect is provided between the disassembling section 30 and the pipe connecting section 40. Here, the third sealing member 90 may be, but not limited to, a ring structure made of rubber.

It should be noted that the number of the sealing members disposed between the disassembly section 30 and the ball plug 20, between the valve seat 10 and the disassembly section 30, and between the disassembly section 30 and the pipeline connection section 40 is not limited to the aforementioned embodiment. When the number of the sealing elements can be changed according to different requirements of the leakage-proof level, different leakage-proof requirements can be met.

In one embodiment, in order to achieve the effect of real-time monitoring, sensors may be further disposed between the first flange portion 121 and the second flange portion 32, between the second flange portion 32 and the third flange portion 41, and between the fourth flange portion 43 and the external pipeline. The coupling states between the first flange portion 121 and the second flange portion 32, between the second flange portion 32 and the third flange portion 41, and between the fourth flange portion 43 and the external pipeline are sensed by the sensors, so as to detect the coupling states between the valve seat 10 and the disassembled sections 30, between the disassembled sections 30 and the pipeline connecting section 40, and between the pipeline connecting section 40 and the external pipeline in real time. In this embodiment, the state of the whole pipe network system can be fed back in real time by combining with the networking mechanism, so that the maintenance personnel can handle the state of loosening or abnormal separation among the elements in real time.

Further, in an embodiment, the sensor may be, but not limited to, a pressure sensor, and when the contact pressure between the first flange portion 121 and the second flange portion 32, between the second flange portion 32 and the third flange portion 41, and between the fourth flange portion 43 and the external pipeline is lower than a predetermined value, it can be determined that there may be a loose condition between the first flange portion 121 and the second flange portion 32, between the second flange portion 32 and the third flange portion 41, and between the fourth flange portion 43 and the external pipeline.

In another embodiment, the sensor may be, but not limited to, a gap sensor, and when the gaps between the first flange portion 121 and the second flange portion 32, between the second flange portion 32 and the third flange portion 41, and between the fourth flange portion 43 and the external pipeline are higher than a predetermined value, the situation that the gaps between the first flange portion 121 and the second flange portion 32, between the second flange portion 32 and the third flange portion 41, and between the fourth flange portion 43 and the external pipeline may be loosened can be determined.

In addition, in each embodiment configured with the sensor, the sensor can be matched with an alarm, and when the sensor judges that abnormal loosening conditions exist among the connecting elements, the sensor can immediately warn on line so as to warn a maintainer to perform detection or maintenance in real time.

Referring to fig. 3 and 5 to 7, in one embodiment, in order to ensure the tightness of the split valve structure during the fluid transportation process, a first sealing member 70 may be further disposed between each of the disassembled sections 30 and the ball plunger 20. The disassembled section 30 has a first ring groove 33 on an end surface thereof opposite to the second flange portion 32, and the first seal 70 is received in the first ring groove 33. In a normal case, the friction between the first seal 70 and the groove wall of the first ring groove 33 may prevent the first seal 70 from easily falling off the first ring groove 33 during the assembly process. However, the first seal 70 may be disengaged from the first ring groove 33 in some cases due to the turning and moving of the disassembled section 30 during the assembling process, which causes inconvenience to the assembling personnel.

In order to prevent the first sealing element 70 from falling out of the first annular groove 33, as shown in fig. 5 to 7, in one embodiment, the first sealing element 70 includes an outer annular surface 72, the outer annular surface 72 has an outer annular groove 74, and the outer annular groove 74 extends along the outer annular surface 72 to form a complete ring shape. Further, at least one stopper 76 is inserted into the outer ring groove 74 from the outer surface of the disassembled section 30 through the disassembled section 30 in a direction perpendicular to the notch of the outer ring groove 74. In some embodiments, the number of stops 76 may be three or more. It should be noted that the outer annular groove 74 extending along the outer annular surface 72 in a complete annular shape provides two benefits, the first being ease of manufacture, i.e., only one milling pass of the milling cutter along the outer annular surface 72 of the first seal 70 is required to form the outer annular groove 74; secondly, the positioning is convenient, that is, the stop parts 76 uniformly distributed on the outer surface of the disassembled section 30 can be inserted into the outer ring groove 74 only by directly locking without special positioning, so as to improve the assembly efficiency.

As shown in fig. 8, in some embodiments, the outer ring groove 74 may be a plurality of concave holes 74A matching with the stop member 76, which still prevents the first sealing member 70 from being removed from the first ring groove 33, without considering the assembling efficiency. As shown in fig. 9, in some embodiments, the outer ring groove 74 may also include a plurality (three in the figure) of discontinuous groove sections 74B, for example, one groove section 74B for each stop 76, and each groove section 74B is independent and unconnected.

When the first seal 70 is located in the first ring groove 33 of the disassembled section 30 and the ball plunger 20 is not received in the seat body 11, that is, the first seal 70 is not yet pressed by the ball plunger 20, the center C2 of the insertion portion of the stopper 76 into the outer ring groove 74 is located below the centerline C1 of the outer ring groove 74, as shown in fig. 5. When the first seal 70 is compressed by the ball plunger 20 received in the seat body 11 with the first seal 70 in the first annular groove 33 of the disassembled section 30, the center C2 of the insertion portion of the stopper 76 into the outer annular groove 74 is substantially located at the centerline C1 of the outer annular groove 74, as shown in fig. 6. In some embodiments, the center C2 of the insertion portion of the stopper 76 into the outer annular groove 74 may also be located below the centerline C1 of the outer annular groove 74 when the first seal 70 is compressed by the ball plunger 20. If the center C2 of the insertion portion of the stopper 76 is located above the centerline C1 of the outer annular groove 74 without being pressed by the ball plunger 20, since the material of the first sealing element 70 is rubber or other polymer material, when the ball plunger 20 is accommodated in the seat body 11 to press the first sealing element 70, the sidewall of the outer annular groove 74 of the first sealing element 70 may touch the stopper 76 due to the elastic material of the first sealing element 70, which may affect the operation of the manifold valve. Alternatively, even if the sidewall of the outer annular groove 74 of the first seal 70 does not touch the stopper 76, but the spacing is too small, the first seal 70 may come into contact with the stopper 76 after a certain period of time as the first seal 70 ages, thereby affecting the operation of the manifold valve.

In some embodiments, when the ball plunger 20 is received in the first annular groove 33, the distance between the upper edge of the portion of the stopper 76 inserted into the outer annular groove 74 and the side wall of the first annular groove 33 is greater than 2mm, and the distance can be adjusted according to the material of the first seal 70 and the use environment.

In addition to the advantages of preventing the first seal 70 from falling off, the above-described embodiment may also provide the function of error detection for field personnel during assembly or maintenance of the manifold valve. For example, during the assembly of the conventional manifold valve, the assembler may not find that the first sealing member 70 is not smoothly inserted into the first annular groove 33, so that the surface of the ball plunger 20 is not uniformly pressed on the first sealing member 70 after the subsequent assembly is completed, and the operation of the manifold valve is jammed or not smooth, and the service life of the first sealing member 70 is greatly shortened. With the above embodiment, as long as the stopper 76 can be smoothly locked into the outer ring groove 74 of the first seal 70, which means that the first seal 70 has been smoothly inserted into the first ring groove 33, the assembler can be relieved to perform the subsequent assembly process. If the stop member 76 is not smoothly locked in, the assembler can check and eliminate the problem of the installation of the first seal member 70.

Naturally, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and it is intended that all such changes and modifications be considered as within the scope of the appended claims.
