Description

Technical Field

[0001] The invention relates to the control of a pipeline by a hydraulic valve of an underwater control module, and in particular to a hydraulic valve component capable of adjusting an internal flow channel. Background Art

[0002] The hydraulic valve is a key automatic control component for the on-off of the internal oil, gas, and water pipeline system of the underwater control module (SCM). It is controlled by the pressure oil of the pressure regulating valve and is usually used in combination with the electromagnetic pressure regulating valve. It can be used to remotely control the on-off of the oil, gas, and water pipeline system of the hydropower station. It is often used for clamping, controlling, lubricating and other oil circuits. It is indispensable in today's industrial production and large-scale equipment. The key part is the internal hydraulic valve block. The general hydraulic valve block is made of one-piece casting and stamping. It is impossible to adjust the internal flow channel such as flow channel blocking, flow channel direction change, and input and output positions according to actual application requirements. When different output directions are required, new hydraulic valves can only be added, which increases the manufacturing cost and is inconvenient to use. The reason is that the configuration between the hydraulic valve blocks is inconvenient and the internal pipeline circulation effect cannot be configured according to the needs.

[0039] In order to fully understand the "configurability" of the present invention, it is assumed that the main channel block 1 in the drawings of the specification of the present invention is fixed, the liquid inlet joint 2 at the upper end of the main channel block 1 is replaceable, and one or two single flow-blocking replacement blocks 3, one or two single-flow replacement blocks 4 or a cross-flow replacement block 5 in the middle of the main channel block 1 can also be combined and replaced. However, this assumption that the main channel block 1 in the drawings of the specification is "fixed" does not mean that the protection scope of the main channel block 1 in the present invention is limited to being non-replaceable. In addition, the directions "left", "right", "up" and "down" involved in the present invention refer to the left, right, up and down relative to the directions of the structures in the drawings of the specification, respectively. "Front" refers to the outside of the paper in the drawings of the specification, and "back" refers to the inside of the paper in the drawings of the specification. The "forward installation" and "reverse installation" involved in the present invention are relative to each other, that is, when the liquid flows into the butt joint 2 and is installed on the upper end of the main channel block 1, it is "forward installation", and when the main channel block 1 is kept unchanged, the liquid flows into the butt joint 2 and is rotated 180 degrees and installed on the upper end of the main channel block 1, it is "reverse installation". It should be noted that the flow channel port interface on the following equipment is preferably a universal or standard component.

[0040] Example 1: Double flow-blocking type

[0041] Embodiment 1 provides a pipeline device whose internal pipeline is a double-blocking type, and its structure is described in detail below.

[0042] refer to Figures 1 to 4 The pipeline device with freely configurable internal pipeline circulation effect comprises a main channel block 1, a liquid inflow joint 2 and several replacement block assemblies. The liquid inflow joint 2 is detachably arranged at the upper end of the main channel block 1 for introducing fluid. The replacement block assembly is detachably arranged in the middle of the main channel block 1, so that the upper left connecting pipe 11 and the upper right connecting pipe 12 at the upper part form a double-blocking, one-blocking and one-passing, double-flow-passing or cross-connected internal pipeline with the lower left connecting pipe 13 and the lower right connecting pipe 14 at the lower part through the replacement block assembly.

[0043] An upper left connecting pipe 11, an upper right connecting pipe 12, a lower left connecting pipe 13 and a lower right connecting pipe 14 are arranged inside the main flow channel block 1. The upper left connecting pipe 11 and the upper right connecting pipe 12 are longitudinally arranged at the upper part of the main flow channel block 1, and the lower left connecting pipe 13 and the lower right connecting pipe 14 are longitudinally arranged at the lower part of the main flow channel block 1. Preferably, the upper left connecting pipe 11 and the upper right connecting pipe 12 are arranged at the same height and parallel to each other, and the lower left connecting pipe 13 and the lower right connecting pipe 14 are arranged at the same height and parallel to each other. Preferably, the inlet of the upper left connecting pipe 11 and the inlet of the upper right connecting pipe 12 are respectively arranged on both sides of the top surface of the main flow channel block 1, and the outlet of the lower left connecting pipe 13 and the outlet of the lower right connecting pipe 14 are respectively arranged on both sides of the bottom surface of the main flow channel block 1.

[0044] In order to facilitate the docking of the upper left connecting tube 11 and the upper right connecting tube 12, the lower left connecting tube 13 and the lower right connecting tube 14 with the replacement block assembly, the bottom of the upper left connecting tube 11 and the upper right connecting tube 12, and the top of the lower left connecting tube 13 and the lower right connecting tube 14 are respectively vertically connected with a short docking tube 10, and each short docking tube 10 is arranged along the thickness direction of the main channel block 1.

[0045] The liquid inflow joint 2 introduces liquid or gaseous fluid, and transports the fluid to the upper left connecting pipe 11 and the upper right connecting pipe 12 of the main channel block 1. Specifically, the liquid inflow joint 2 is provided with a first transverse liquid flow channel 21, a second transverse liquid flow channel 22 and a longitudinal liquid flow channel 23. The first transverse liquid flow channel 21 and the second transverse liquid flow channel 22 merge inside the liquid inflow joint 2 to form a transverse confluence outlet. The transverse confluence outlet and the outlet of the longitudinal liquid flow channel 23 are provided on the bottom surface of the liquid inflow joint 2.

[0046] Further, the first transverse liquid flow channel 21 includes a first liquid inlet pipe, and the second transverse liquid flow channel 22 includes a second liquid inlet pipe, and the first liquid inlet pipe and the second liquid inlet pipe are arranged along the thickness direction of the liquid inlet joint 2 and are parallel to each other. The inlet of the first liquid inlet pipe and the inlet of the second liquid inlet pipe are respectively located on the front side and the rear side of the liquid inlet joint 2. Specifically, the first liquid inlet pipe and the second liquid inlet pipe are connected through a connecting pipe, wherein the connecting pipe is longitudinally arranged in the liquid inlet joint 2 along the length of the liquid inlet joint 2. The inlet of the longitudinal liquid flow channel 23 is arranged on one of the side surfaces at both ends of the liquid inlet joint 2. When the liquid inlet joint 2 is positively installed at the upper end of the main channel block 1, the outlet of the longitudinal liquid flow channel 23 and the transverse confluence outlet are respectively connected to the inlet of the upper left connecting pipe 11 and the inlet of the upper right connecting pipe 12.

[0047] The replacement block assembly is detachably arranged in the middle of the main channel block 1, so that the communication relationship between the upper left connecting pipe 11 and the upper right connecting pipe 12 located at the upper part and the lower left connecting pipe 13 and the lower right connecting pipe 14 located at the lower part is a double-blocking, one-blocking and one-passing, double-direct-passing or cross-connecting type.

[0048] Specifically, in Embodiment 1, the replacement block assembly is a combination of two single flow-blocking replacement blocks 3, each single flow-blocking replacement block 3 is not provided with a flow-through pipeline, one of the single flow-blocking replacement blocks 3 can block the flow between the outlet of the butt joint short pipe 10 of the upper left connecting pipe 11 and the inlet of the lower left connecting pipe 13, and the other single flow-blocking replacement block 3 blocks the flow between the outlet of the butt joint short pipe 10 of the upper right connecting pipe 12 and the inlet of the lower right connecting pipe 14. When the two single flow-blocking replacement blocks 3 are connected and arranged in the middle of the main flow channel block 1 by bolt connection, the flow between the outlet of the butt joint short pipe 10 of the upper left connecting pipe 11 and the inlet of the lower left connecting pipe 13 is blocked by one of the single flow-blocking replacement blocks 3, and the flow between the outlet of the butt joint short pipe 10 of the upper right connecting pipe 12 and the inlet of the lower right connecting pipe 14 is blocked by the other single flow-blocking replacement block 3, thereby forming a pipeline device in which the flow type of the internal pipeline is a double flow-blocking type.

[0049] Working process: the fluid flows into the docking joint 2 from one, two or three of the three inlets of the first transverse liquid flow channel 21, the second transverse liquid flow channel 22 and the longitudinal liquid flow channel 23. The fluids in the first transverse liquid flow channel 21 and / or the second transverse liquid flow channel 22 merge and flow into the inlet of the upper left connecting pipe 11 or the inlet of the upper right connecting pipe 12 through the transverse merging outlet. The fluid in the longitudinal liquid flow channel 23 flows into the inlet of the upper right connecting pipe 12 or the inlet of the upper left connecting pipe 11. The fluids in the inlet of the upper left connecting pipe 11 or the upper right connecting pipe 12 are blocked by two single flow blocking replacement blocks 3 respectively and cannot continue to circulate.

[0050] Example 2: Left-pass and right-blocking type

[0051] Embodiment 2 provides a pipeline device with an internal pipeline of the left-through and right-blocking type. Based on Embodiment 1, the difference of Embodiment 2 is that the replacement block assembly is a combination of a single-blocking flow replacement block 3 and a single-through flow replacement block 4. Among them, the external shape and geometric dimensions of the single-blocking flow replacement block 3 and the single-through flow replacement block 4 are exactly the same, that is, the single-blocking flow replacement block 3 and the single-through flow replacement block 4 are both rectangular parallelepipeds, and the length, width and thickness of the external dimensions of the two are the same.

[0052] refer to Figures 5 to 8There is no flow-through pipeline in the single-blocking flow replacement block 3. The single-blocking flow replacement block 3 can block the flow between the outlet of the upper right connecting pipe 12 and the inlet of the lower right connecting pipe 14. A straight flow-through pipeline 41 is longitudinally provided in the single-flow replacement block 4. The outlet of the upper left connecting pipe 11 can be connected to the inlet of the lower left connecting pipe 13 through the longitudinal flow-through pipeline 41 of the single-flow replacement block 4.

[0053] When the single-flow replacement block 4 and the single-blocking replacement block 3 are respectively fixed to the left and right sides of the middle of the main channel block 1 by bolts, the outlet of the butt joint short pipe 10 of the left upper connecting pipe 11 on the left side and the inlet of the left lower connecting pipe 13 are connected due to the single-flow replacement block 4, and the outlet of the butt joint short pipe 10 of the right upper connecting pipe 12 and the inlet of the right lower connecting pipe 14 on the right side are blocked due to being blocked by the single-blocking replacement block 3, thereby forming a pipeline device with a flow type of left-through and right-blocking type of internal pipeline. In this case, the fluid in the left upper connecting pipe 11 on the left side can flow smoothly through the longitudinal flow pipeline 41 of the single-flow replacement block 4, but the fluid in the right upper connecting pipe 12 on the right side is blocked by the single-blocking replacement block 3 and cannot continue to flow.

[0054] Example 3: Left-blocking and right-passing type

[0055] Example 3 provides a pipeline device with an internal pipeline of the left-blocking and right-passing type. The internal structure of Example 3 is basically the same as that of Example 2, and the replacement block assembly is also a single-blocking replacement block 3 and a single-passing replacement block 4.

[0056] The difference between Example 3 and Example 2 is that, Figures 9 to 12 , the single-flow replacement block 4 is fixed on the right side of the middle of the main channel block 1, and the outlet of the upper right connecting pipe 12 can be connected to the inlet of the lower right connecting pipe 14 through the longitudinal flow pipeline 41 of the single-flow replacement block 4. The single-blocking flow replacement block 3 is fixed on the left side of the middle of the main channel block 1. The upper left connecting pipe 11 and the upper right connecting pipe 12 on the right side are connected due to the single-flow replacement block 4, and the upper left connecting pipe 11 and the lower left connecting pipe 13 on the left side are blocked due to the obstruction of the single-blocking flow replacement block 3, thereby forming a pipeline device with a right-open and left-blocking type of internal pipeline. In this case, the fluid in the upper left connecting pipe 11 on the left side is blocked by the single-blocking flow replacement block 3 and cannot continue to flow, but the fluid in the upper right connecting pipe 12 on the right side can flow smoothly through the longitudinal flow pipeline 41 of the single-flow replacement block 4.

[0057] It should be noted that, whether it is a left-blocked right-pass type pipeline or a left-pass right-blocked type pipeline, they are all one-pass and one-blocked type pipelines. During the test, it is relatively easy to simply swap the single-blocked flow replacement block 3 and the single-pass flow replacement block 4, which may not be worth mentioning. However, in actual industrial production, due to the huge investment in the water inlet pipeline and the water outlet pipeline, in order to ensure safety, the water inlet pipeline and the water outlet pipeline are usually pre-set and will not be easily changed. The main channel block 1 is sometimes fixed or difficult to disassemble and replace. Therefore, for some special cases such as space constraints and differences in the inflow of liquid on both sides, when there are strict requirements for the single-side pass or block of the main channel block 1, the selection of standard parts for established pipeline modes such as right-pass left-blocked pipelines and left-pass right-blocked pipelines in the internal pipeline circulation mode can often produce better results in terms of economy and technology, and can adapt to market demand.

[0058] Embodiment 4: Dual DC type

[0059] Example 4 provides a pipeline device with an internal pipeline of a dual direct-flow type, which is based on Example 1. The difference between Example 4 and Example 1 is that the replacement block assembly is a combination of two single-flow replacement blocks 4.

[0060] refer to Figures 13 to 16 A straight flow pipeline 41 is longitudinally provided in each single-flow replacement block 4, and the outlet of the docking short tube 10 of the upper left connecting tube 11 is connected to the inlet of the lower left connecting tube 13 through one of the longitudinal flow pipelines 41 of the single-flow replacement block 4, and the outlet of the docking short tube 10 of the upper right connecting tube 12 is connected to the inlet of the lower right connecting tube 14 through the longitudinal flow pipeline 41 of another single-flow replacement block 4.

[0061] When two single-flow replacement blocks 4 are arranged on the main channel block 1, the flow between the outlet of the docking short tube 10 of the upper left connecting tube 11 and the inlet of the lower left connecting tube 13 becomes smooth, and the flow between the outlet of the docking short tube 10 of the upper right connecting tube 12 and the inlet of the lower right connecting tube 14 becomes smooth, forming a pipeline device in which the flow type of the internal pipeline is a double direct flow type pipeline.

[0062] Example 5: Cross-flow type

[0063] Example 5 provides a pipeline device with a cross-flow type internal pipeline. Based on Example 1, the difference between Example 5 and Example 1 is that the replacement block assembly is a cross-flow replacement block 5.

[0064] refer to Figures 17 to 20 The thickness and vertical length of the cross-flow replacement block 5 are the same as those of the single-blocking flow replacement block 3 and the single-flow replacement block 4. The horizontal width of the cross-flow replacement block 5 is equal to the width of two single-blocking flow replacement blocks 3, two single-flow replacement blocks 4, or one single-blocking flow replacement block 3 and one single-flow replacement block 4 and the gap in between.

[0065] The space inside the cross-flow replacement block 5 is cross-arranged with a first curved flow pipeline 51 and a second curved flow pipeline 52. The first curved flow pipeline 51 and the second curved flow pipeline 52 are formed by multiple connecting pipes connected inside the cross-flow replacement block 5, and the relationship between the first curved flow pipeline 51 and the second curved flow pipeline 52 inside the cross-flow replacement block 5 is spatially crossed and not overlapped. Specifically, the outlet of the docking short pipe 10 of the upper left connecting pipe 11 is connected to the inlet of the docking short pipe 10 of the lower right connecting pipe 14 through the first curved flow pipeline 51, and the outlet of the docking short pipe 10 of the upper right connecting pipe 12 is connected to the inlet of the docking short pipe 10 of the lower left connecting pipe 13 through the second curved flow pipeline 52.

[0066] Specifically, refer to Fig.21 The first curved through-flow pipeline 51 includes a first curved through-flow upper butt-joint pipe 511, a first longitudinal vertical upper connecting pipe 512, a first horizontal connecting pipe 513, a first longitudinal vertical lower connecting pipe 514 and a first curved through-flow lower butt-joint pipe 515 which are vertically connected in sequence from top to bottom and from left to right.

[0067] The second curved through-flow pipeline 52 includes a second curved through-flow upper butt-joint pipe 521, a second upper horizontal curved connecting pipe 522, a second longitudinal vertical connecting pipe 523, a second lower horizontal curved connecting pipe 524, and a second curved through-flow lower butt-joint pipe 525, which are vertically connected in sequence from top to bottom and from right to left.

[0068] When the cross-flow replacement block 5 is arranged in the middle of the main channel block 1, the first bend flow upper docking tube 511 and the first bend flow lower docking tube 515 are respectively connected to the outlet of the docking short tube 10 of the upper left connecting tube 11 and the inlet of the docking short tube 10 of the lower right connecting tube 14 in a straight line, and the second bend flow upper docking tube 521 and the second bend flow lower docking tube 525 are respectively connected to the outlet of the docking short tube 10 of the upper right connecting tube 12 and the inlet of the docking short tube 10 of the lower left connecting tube 13.

[0069] When the cross-flow replacement block 5 is set in the middle of the main channel block 1, the fluid in the upper left connecting pipe 11 flows into the lower right connecting pipe 14 through the first cross-flow pipeline 51, and the fluid in the upper right connecting pipe 12 flows into the lower left connecting pipe 13 through the second cross-flow pipeline 52, forming a pipeline device in which the flow type of the internal pipeline is a cross-flow type pipeline.

[0070] Example 6: Configuration of the liquid inflow joint and the main channel block

[0071] Example 6 provides a variety of configurations of the liquid inlet butt joint and the main channel block to form a liquid inlet butt joint pipeline device with a variety of different configurations. Based on Example 1, the difference between Example 6 and Example 1 is that the liquid inlet butt joint 2 has a variety of different structural forms and configurations with the main channel block 1. Its structural forms and configurations are described in detail below.

[0072] Compared with the above embodiments, the differences in the structure and configuration of the liquid inflow joint 2 provided in Embodiment 6 include the following aspects:

[0073] 1. Arrangement of the first lateral liquid flow channel 21 and the second lateral liquid flow channel 22

[0074] The first liquid inlet inlet of the first transverse liquid flow channel 21 and the second liquid inlet inlet of the second transverse liquid flow channel 22 can be respectively arranged on the front side and the rear side of the liquid flowing into the docking joint 2, or can be arranged on the same side of the front side or the rear side in the thickness direction of the liquid flowing into the docking joint 2. Fig. 22 and Fig.23 .

[0075] 2. Setting of the longitudinal flow channel 23

[0076] The inlet of the longitudinal liquid flow channel 23 can be set not only on one side surface of the two ends of the liquid inflow joint 2, but also on the top surface of the liquid inflow joint 2.

[0077] 3. Configuration of the liquid inflow joint 2 and the main channel block 1

[0078] The liquid inflow joint 2 can be installed not only in the forward direction but also in the reverse direction at the upper end of the main flow channel block 1. That is, when the liquid inflow joint 2 is installed in the forward direction at the upper end of the main flow channel block 1, the outlet of the longitudinal liquid flow channel 23 and the transverse confluence outlet are respectively connected to the inlet of the upper left connecting pipe 11 and the inlet of the upper right connecting pipe 12. When the liquid inflow joint 2 is rotated 180 degrees and installed in the reverse direction at the upper end of the main flow channel block 1, the transverse confluence outlet and the outlet of the longitudinal liquid flow channel 23 are respectively connected to the inlet of the upper left connecting pipe 11 and the inlet of the upper right connecting pipe 12. Fig. 9 and Fig.24 .

[0079] 4. Adjustment of input and output positions

[0080] One adjustment method is to select one, two or three from the first transverse liquid flow channel 21, the second transverse liquid flow channel 22 and the longitudinal liquid flow channel 23 as the fluid input inlet, that is, there are 7 input forms; select one or two from the lower left connecting tube 13 and the lower right connecting tube 14 as the fluid input outlet, that is, there are 3 output forms.

[0081] Another adjustment method is to turn the entire device upside down, and use one or two of the lower left connecting tube 13 and / or the lower right connecting tube 14 as the fluid input inlet, and one or two or three of the first transverse liquid flow channel 21, the second transverse liquid flow channel 22 and / or the longitudinal liquid flow channel 23 as the fluid input outlet.

[0082] In summary, by changing the structural form of the liquid inflow joint 2, and selecting the number and type of single-blocking flow replacement blocks 3 and / or single-pass flow replacement blocks 4 or cross-pass flow replacement blocks 5 to be configured on the main channel block 1, a pipeline device with different flow effect pipelines is formed. The flow types of the internal pipelines of these pipeline devices include double-blocking flow pipelines, one-pass and one-resistance pipelines, double-straight-flow pipelines and cross-flow pipelines, among which the one-pass and one-resistance pipeline can be divided into left-pass and right-resistance pipelines and right-pass and left-resistance pipelines. The free configuration between each replacement block and the main channel block 1 and the flow effect produced are as follows:

[0083] The first type is that two single-blocking replacement blocks 3 are arranged on the main channel block 1 to form a double-blocking type pipeline device;

[0084] The second type is that a single flow-blocking replacement block 3 and a single flow-through replacement block 4 are arranged on the main channel block 1 to form a left-through and right-blocking type pipeline device;

[0085] The third type is that a single flow-blocking replacement block 3 and a single flow-through replacement block 4 are arranged on the main channel block 1 to form a left-blocking and right-through type pipeline device;

[0086] In the fourth method, two single-flow replacement blocks 4 are arranged on the main channel block 1 to form a dual-flow type pipeline device;

[0087] Fifth, a cross-flow replacement block 5 is arranged on the main channel block 1 to form a cross-flow type pipeline device.

[0088] The structure and configuration of the liquid inflow joint 2 include:

[0089] 1. The inlet of the first transverse liquid flow channel 21 and the inlet of the second transverse liquid flow channel 22 are arranged on the same side or the opposite side of the side where the liquid flows into the butt joint 2;

[0090] 2. The inlet of the longitudinal liquid flow channel 23 is arranged at the top surface or end surface of the joint 2 where the liquid flows in.

[0091] 3. The liquid flows into the butt joint 2 at the upper end of the main channel block 1 in a forward or reverse manner.

[0092] 4. Selection of input and output form and location.

[0093] During use, the single-block replacement block 3, single-pass replacement block 4 or cross-pass replacement block 5 is selected according to the needs, the structure and configuration of the liquid inlet joint 2 are selected, and then the liquid inlet joint 2 and the single-block replacement block 3, single-pass replacement block 4 or cross-pass replacement block 5 are respectively arranged on the main channel block 1 to form a pipeline device, and then the pipeline device is connected to the hydraulic valve. Different assemblies of the replacement block assembly and the main channel block 1, as well as different structures and configurations of the liquid inlet joint 2, achieve different output effects. When damaged, the damaged parts can be directly disassembled and replaced.

[0094] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
