Description

Technical Field

[0001] The utility model relates to the technical field of a sheet-type multi-way valve, in particular to a sheet-type multi-way valve. Background Art

[0002] The multi-way valve is a control element widely used in various hydraulic systems. Its main structure consists of multiple valve plates, each of which can independently control the action of one or more hydraulic actuators. The main advantage of the multi-way valve is its compact structure and ability to realize complex hydraulic control functions. The working principle of the multi-way valve is based on the design of the valve core and valve seat inside it. When the control element such as the handle or solenoid is operated, the valve core moves to change the size or direction of the valve port, thereby controlling the flow direction and flow rate of the hydraulic oil. Various complex hydraulic control logics can be realized through the combination and configuration of different valve plates. Multi-way valves are widely used in construction machinery such as excavators, loaders, forklifts, etc. In these equipment, the multi-way valve is responsible for controlling the actions of various working devices, such as the lifting, extension and rotation of the boom, dipper rod, bucket, etc. By accurately controlling the multi-way valve, efficient, stable and safe operation of construction machinery can be achieved.

[0003] At present, in the process of assembling a sheet-type multi-way valve, it is necessary to evenly stack multiple valve sheets together, then string the valve sheets together with three connecting rods, and finally fix them with bolts. However, there is a lack of connection structure between the valve sheets, and the position of each valve sheet needs to be constantly adjusted when inserting the connecting rod, which is time-consuming and affects the assembly efficiency of the sheet-type multi-way valve.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] See also Figure 1-4 The present embodiment provides a chip-type multi-way valve, including a single chip multi-way valve 1, a docking groove 101 is provided on both side surfaces of the single chip multi-way valve 1, a hexagonal groove 28 is provided between the centers of the two side surfaces of the single chip multi-way valve 1, a connecting plate 4 is symmetrically installed on both side surfaces of the single chip multi-way valve 1, a positioning cover 5 is symmetrically installed at the edges of the two side surfaces of the connecting plate 4, the positioning cover 5 matches the inner side surface size of the docking groove 101, a hexagonal groove 7 is provided between the centers of the two side surfaces of the connecting plate 4, and a hexagonal docking rod 9 is inserted into the inner side of the hexagonal groove 7. In the process of assembling the chip-type multi-way valve, first, insert the positioning cover 5 on a connecting plate 4 into the docking groove 101 on the side surface of a single chip multi-way valve 1. The connecting plate 4 is then installed on the inner side of the connecting groove 101, and then a single-piece multi-way valve 1 is installed on the other side of the connecting plate 4. At this time, the connecting plate 4 continues to be installed on one side of the single-piece multi-way valve 1. This is repeated until all the single-piece multi-way valves 1 are installed. Then the hexagonal connecting rod 9 is passed through the hexagonal groove 1 7 and the hexagonal groove 2 8 to complete the assembly of the sheet-type multi-way valves. At this time, the structure between each single-piece multi-way valve 1 is stable and compact, which is convenient for the subsequent installation of the overall structure. There is no need to use three connecting rods to string the single-piece multi-way valves 1 together, which avoids the need to adjust the single-piece multi-way valves 1 one by one to facilitate the insertion of the connecting rods during the assembly of the sheet-type multi-way valves, thereby effectively improving the assembly efficiency of the sheet-type multi-way valves.

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, the position between the two side edges of the connecting plate 4 and the positioning cover 5 is made of rubber material, and the two side edges of the connecting plate 4 overlap with the side edges of the two single-chip multi-way valves 1 and squeeze each other, thereby improving the connection sealing between the single-chip multi-way valves 1 and avoiding deformation caused by direct squeezing between the single-chip multi-way valves 1.

[0029] In this embodiment, if Figure 2 and Figure 4As shown, one end of the interior of the docking groove 101 is paved with metal material, and a magnet sheet 6 is fixedly installed on the outer surface of the positioning cover 5. The size of the positioning cover 5 and the magnet sheet 6 after splicing is the same as the size of the interior of the docking groove 101. Therefore, after the positioning cover 5 is inserted into the docking groove 101, the magnet sheet 6 will be adsorbed on one end of the interior of the docking groove 101, so that the single-piece multi-way valve 1 stacked by the connecting plate 4 has a compact structure and is not easy to loosen, which is convenient for operation.

[0030] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, after the docking grooves 101 are opened on both sides of the single-chip multi-way valve 1, the remaining part is a convex block, and the convex block has the same size as the inner side surface of the positioning cover 5 and the magnet sheet 6 on both sides of the connecting plate 4 after splicing. At the same time, the convex block will be inserted into the inner side of the positioning cover 5 and the magnet sheet 6 when assembling the chip-type multi-way valve, thereby improving the overall stability of the chip-type multi-way valve.

[0031] In this embodiment, if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a limit baffle 10 is fixedly installed on one end of the hexagonal docking rod 9, and a threaded head 11 is fixedly installed on the other end of the hexagonal docking rod 9. The hexagonal docking rod 9 is inserted from the hexagonal groove on the outer side of the return oil tank 2, and passes through multiple single-chip multi-way valves 1 and the hexagonal groove 1 7 and the hexagonal groove 2 8 on the connecting plate 4 in sequence, and then passes through the outer side of the hydraulic pump 3 to expose the threaded head 11. The outer side of the hydraulic pump 3 is threadedly connected to the threaded head 11 through a nut, so that only one hexagonal docking rod 9 is needed to fix multiple single-chip multi-way valves 1, the return oil tank 2 and the hydraulic pump 3 together.

[0032] Working principle: When assembling the sheet-type multi-way valve, first insert the positioning cover 5 on a connecting plate 4 into the inner side of the docking groove 101 on the side of a single-piece multi-way valve 1, and then install another single-piece multi-way valve 1 on the other side of the connecting plate 4. At this time, continue to install the connecting plate 4 on one side of the single-piece multi-way valve 1, and repeat this process until all the single-piece multi-way valves 1 are installed. After the positioning cover 5 is inserted into the docking groove 101, the magnet sheet 6 will be adsorbed on the inner end of the docking groove 101, so that the single-piece multi-way valve 1 stacked by the connecting plate 4 is compact and not easy to loosen, and is easy to operate. At the same time, docking grooves 101 are opened on one side of the return oil tank 2 and the hydraulic pump 3, and the outer sides of each single-piece multi-way valve 1 at both ends of the sheet-type multi-way valve are connected to the return oil tank 2 and the hydraulic pump 3 through the connecting plate 4. The docking groove 101 is docked, and finally the hexagonal docking rod 9 is inserted into the hexagonal groove on the outer side of the return oil tank 2, and passes through multiple single-chip multi-way valves 1 and the hexagonal groove one 7 and the hexagonal groove two 8 on the connecting plate 4 in turn, and then passes through the outer side of the hydraulic pump 3 to expose the threaded head 11. The outer side of the hydraulic pump 3 is threadedly connected with the threaded head 11 through a nut, so that only one hexagonal docking rod 9 is needed to fix the multiple single-chip multi-way valves 1 as well as the return oil tank 2 and the hydraulic pump 3 together. At this time, the structure between each single-chip multi-way valve 1 is stable and compact, which is convenient for the subsequent installation of the overall structure. There is no need to use three connecting rods to string the single-chip multi-way valves 1 together, which avoids the need to adjust the single-chip multi-way valves 1 one by one to facilitate the insertion of the connecting rod during the assembly of the chip-type multi-way valves, thereby effectively improving the assembly efficiency of the chip-type multi-way valves.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
