Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic circuits, and in particular to a pressure reducing valve for hydraulic circuits. Background Technology

[0002] Hydraulic circuits convert hydraulic energy into mechanical energy through hydraulic components (such as pumps, valves, and cylinders) to drive actuators to complete specified actions. In the use of hydraulic circuits, pressure reducing valves are frequently used to lower water pressure by reducing the local resistance to flow through their internal channels.

[0003] When using a pressure reducing valve, workers connect the pipe to the valve using a flange. Although this structure is simple, it requires rotating the bolts one by one to connect the pipe to the valve, which is inefficient and limited by the tools available. Utility Model Content

[0007] In addition, the pressure reducing valve for hydraulic circuits proposed above according to this utility model may also have the following additional technical features: Specifically, the pressure reducing valve includes a valve body, an inlet pipe, and an outlet pipe, wherein the inlet pipe and the outlet pipe are respectively located on the outside of the valve body.

[0008] Specifically, limit plates are installed on the outside of the valve body and the water inlet pipe.

[0009] Specifically, the sealing assembly is disposed on the connecting mechanism, wherein the sealing assembly includes a first sealing ring, a second sealing ring and a third sealing ring, wherein the inner bottom wall of the connecting ring is provided with the first sealing ring; the side wall of the baffle is provided with the second sealing ring; and the side wall of the threaded pipe is provided with the third sealing ring.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0015] The following describes a hydraulic oil circuit pressure reducing valve according to an embodiment of the present invention with reference to the accompanying drawings.

[0016] like Figures 1-2 As shown, the hydraulic oil circuit pressure reducing valve of this utility model embodiment includes: a pressure reducing valve 1 and two sets of connecting mechanisms 3.

[0017] Two sets of connecting mechanisms 3 are respectively set at both ends of the pressure reducing valve 1. The connecting mechanism 3 includes a connecting ring 31, a connecting pipe 32, a baffle 33, an inner pipe 34, and a threaded pipe 35.

[0018] The connecting ring 31 is located outside the pressure reducing valve 1, the connecting pipe 32 is located inside the pressure reducing valve 1, the baffle 33 is connected to the other end of the connecting pipe 32, the inner pipe 34 is installed inside the connecting pipe 32, and the threaded pipe 35 is connected to the inner pipe 34.

[0019] It should be noted that the inner pipe 34 described in this embodiment is fixedly connected to the pipeline. The connecting pipe 32 described is fixed inside the inlet pipe 12 and outlet pipe 13 of the pressure reducing valve 1.

[0020] Specifically, when it is necessary to connect the external delivery pipe to the pressure reducing valve 1, the operator can install the pipe into the connecting pipe 32 through the inner pipe 34, and then rotate the connecting ring 31 to connect it to the threaded pipe 35. When the connecting ring 31 contacts the baffle 33, the external delivery pipe is connected to the pressure reducing valve 1.

[0021] In one embodiment of this utility model, such as Figure 2 As shown, the pressure reducing valve 1 includes a valve body 11, an inlet pipe 12, and an outlet pipe 13.

[0022] The inlet pipe 12 and the outlet pipe 13 are respectively located on the outside of the valve body 11.

[0023] Understandably, once the pressure reducing valve 1 is connected, the medium will enter the valve body 11 through the inlet pipe 12 and then be discharged through the outlet pipe 13, thereby completing the pressure reduction.

[0024] In one embodiment of this utility model, such as Figure 2 As shown, limit plates 4 are respectively provided on the outside of the valve body 11 and the water inlet pipe 12.

[0025] Understandably, the limiting plate 4 can restrict the position of the connecting ring 31 in the inlet pipe 12 and the outlet pipe 13.

[0026] In one embodiment of this utility model, such as Figure 2 As shown, the sealing component 5 is mounted on the connecting mechanism 3.

[0027] The sealing assembly 5 includes a first sealing ring 51, a second sealing ring 52 and a third sealing ring 53. The first sealing ring 51 is provided on the inner bottom wall of the connecting ring 31, the second sealing ring 52 is provided on the side wall of the baffle 33 and the third sealing ring 53 is provided on the side wall of the threaded pipe 35.

[0028] Understandably, through the arrangement of the first sealing ring 51, the second sealing ring 52, and the third sealing ring 53, after the pressure reducing valve 1 is connected to the external pipeline via the connecting mechanism 3, the first sealing ring 51 can seal the connection point between the baffle 33 and the connecting ring 31. The second sealing ring 52 can further seal the connection point between the baffle 33 and the connecting ring 31, and make the threaded connection between the connecting ring 31 and the threaded pipe 35 more secure. Finally, the third sealing ring 53 can seal the connection point between the connecting pipe 32 and the threaded pipe 35.

[0029] In summary, by adding a connecting mechanism and using threaded pipes, the pipeline and pressure reducing valve can be quickly connected, thereby improving the work efficiency of staff during inspection and maintenance.
