Description

Technical Field

[0001] The utility model belongs to the technical field of sequential valve groups, and in particular relates to a multi-directional sequential valve group. Background Art

[0002] A sequence valve is a valve that controls the sequence of actuator actions based on the pressure of the circuit in a system with more than two branch circuits. The sequence valve can also be used as an unloading valve and a back-pressure valve. According to the working principle and structure, the sequence valve is divided into direct-acting and pilot-operated types. According to the pressure control method, the sequence valve is divided into internal control and external control.

[0003] Existing sequential valve groups usually only transport oil in a single direction. When oil needs to be transported in multiple locations, the staff needs to install multiple sequential valve groups to transport oil to multiple locations, which increases the cost of use. Therefore, we propose a multi-directional sequential valve group. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-directional sequential valve group, by setting a diversion component, specifically connecting several oil pipes on the right side of the sequential valve body to the oil pipeline. When there is oil inside the oil pipeline, the oil inside the oil pipeline will be discharged through opening two and opening one and enter the delivery pipeline for transportation, thereby realizing multi-directional functions. There is no need for staff to install multiple sequential valves, reducing the cost of use, and solving the problem that the sequential valve group usually only transports oil in a single direction. When this method needs to transport oil at multiple locations, the staff needs to install multiple sequential valve groups to transport oil to multiple locations, thereby increasing the cost of use.

[0005] In order to solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a multi-directional sequential valve group, including a sequential valve body, three diverter assemblies are arranged on the right side of the sequential valve body, the three diverter assemblies are arranged in a vertical array, and the three diverter assemblies contain the same parts. A threaded groove is opened on the top of the sequential valve body, and a threaded block is threadedly connected to the inner wall of the threaded groove. An oil drain pipe is fixedly connected to the right side of the sequential valve body;

[0007] The diversion assembly includes an oil pipe, a flow groove is provided inside the sequential valve body, a lifting valve is slidably connected to the inner wall of the flow groove, an oil inlet is provided on the left side of the flow groove, and a guide groove is provided at the bottom of the oil inlet. By setting the diversion assembly, specifically connecting several oil pipes on the right side of the sequential valve body to the oil pipeline, when there is oil in the oil pipe, the oil in the oil pipe will be discharged through opening two and opening one and enter the delivery pipeline for delivery, thereby realizing multi-directional function, eliminating the need for staff to install multiple sequential valves, and reducing usage costs.

[0008] Furthermore, the oil inlet and the guide groove are interconnected, the guide groove and the flow groove are interconnected, a through hole is provided at the central axis of the lifting valve, a plurality of annular grooves are provided on the outer surface of the lifting valve, and a plurality of diversion holes are provided inside the plurality of annular grooves.

The left side of the fixed disk contacts with a turntable. By setting the fan-shaped groove, the moving distance of the connecting block can be limited, so that the position of the turntable can be adjusted more conveniently to control the required flow rate.

[0010] Furthermore, a plurality of openings 1 are provided inside the fixed disk, and a plurality of openings 2 are provided inside the rotating disk, and the openings 1 and 2 are interconnected, and a tapered shaft is rotatably connected to the central axis of the rotating disk, and two sealing rings are sleeved on the outer surface of the rotating disk, and a connecting block is slidably connected to the inner wall of the fan-shaped groove, and the top of the connecting block is fixedly connected to the inner wall of the rotating ring, and the bottom of the connecting block is fixedly connected to the top of the rotating disk, and the right side of the tapered shaft is fixedly connected to the left side of the fixed disk.

When opening 2 is not connected to opening 1, the oil pipeline is sealed, thereby stopping oil transportation, and it can be adjusted according to different needs.

[0011] Furthermore, the bottom of the threaded block contacts an adjusting block, the top of the adjusting block is fixedly connected to a limiting ring, the bottom of the limiting ring is rotatably connected to the bottom of the threaded block, the bottom of the adjusting block is fixedly connected to a spring, and the inner ring of the spring is provided with three limiting rods. When the threaded block moves downward, it drives the adjusting block to move downward, which will squeeze the spring, thereby increasing the oil pressure.

The oil inside the oil pipe 111 will be discharged through the second opening 44 and the first opening 41 and enter the delivery pipeline for transportation, which can realize multi-directional function and does not require staff to install multiple sequence valves, reducing the use cost. By rotating the swivel 113 to drive the connecting block 31 to rotate, the connecting block 31 drives the turntable 42 to rotate, thereby adjusting the opening size between the second opening 44 and the first opening 41, and the flow rate of the oil can be adjusted. When the second opening 44 is not connected to the first opening 41, the oil pipe 111 is sealed, thereby stopping the oil transportation. It can be adjusted according to different needs. The sealing ring 45 is used to play a sealing role to prevent oil leakage.
