Description

Technical Field

[0001] The utility model relates to the technical field of four-way valves, in particular to a four-way valve used for oil pipeline diversion. Background Art

[0002] A four-way valve is a valve device with four pipe openings, one for inlet and three for outlet. Pipes are connected through these four openings. However, when connecting pipes, sometimes pipes need to be installed in three directions of the valve body, while other times, three pipes need to be installed in a single direction. However, current four-way valves can only be installed in one direction, making it impossible to selectively install pipes in different directions of the valve body as needed, making installation inconvenient. Furthermore, once the pipe is installed in one direction, changing its direction requires bending the pipe, which can easily damage it and cause it to flatten, hindering circulation. Utility Model Content

[0007] In the above technical solution, the handle is rotated to drive the transmission rod to rotate, and the first bevel gear and the second bevel gear cooperate to drive the screw to rotate.

[0008] Preferably, a groove is provided on the liquid outlet pipe on the inner side of the cover shell, the pressure plate is located in the groove, and a sealing ring is embedded on the bottom wall of the groove.

[0009] In the above technical solution, when the valve plate is completely sealed in the liquid outlet pipe, the pressure plate is pressed tightly in the groove and the sealing ring prevents liquid from entering the housing.

[0010] Preferably, the top wall and the bottom wall in the liquid outlet pipe are respectively connected to two limit platforms, and the valve plate is movably arranged between the two limit platforms.

[0011] The above technical solution can limit the movement of the valve plate by setting the limit platform, so that it maintains linear motion.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-4 A four-way valve for diverting oil pipelines includes a valve body 1. An inlet pipe 2 is connected to one side of the valve body 1, and three outlet pipes 3 are connected to the other side of the valve body 1. Each end of the valve body 1 is connected to an outlet pipe 3. The inlet pipe 2 is connected to a first flange 4, and each outlet pipe 3 is connected to a second flange 5. Each outlet pipe 3 is provided with a control valve. The outlet pipes can be installed in different directions according to on-site installation requirements, thereby improving installation adaptability. Furthermore, once installed in different directions, the pipes can transport liquid in different directions without bending the pipes, reducing damage to the pipes and preventing them from being squeezed, thereby facilitating liquid flow.

[0025] The control valve in the outlet pipe without a pipeline is closed to prevent liquid leakage, while the control valve in the outlet pipe with a pipeline is open to allow liquid to flow into the pipeline. In addition, the control valve in any outlet pipe can be controlled to open or close to open or close the corresponding outlet pipe as needed.

[0026] Moreover, this embodiment is not limited to a four-way connection, and pipelines can be added or reduced as needed to expand the scope of use.

[0027] The control valve includes a valve plate 6 movably disposed in the liquid outlet pipe, a pressure plate 7 connected to the valve plate, a connecting rod 8 connected to the pressure plate, a lifting plate 9 connected to the connecting rod, a cover 10 connected to the outside of the liquid outlet pipe, a guide rod 11 connected to the cover and the liquid outlet pipe, a screw rod 12 rotatably connected to the cover and the liquid outlet pipe, and a driving mechanism provided on the cover and used to drive the screw rod 12 to rotate, so that the valve plate 6 can be completely sealed in the liquid outlet pipe 3 by driving the screw rod 12 to rotate. Specifically, the driving mechanism includes a transmission rod 13 rotatably connected to the cover, a handle 14 connected to the outer end of the transmission rod, a first bevel gear 15 connected to the inner end of the transmission rod, and a second bevel gear 16 connected to the screw rod, wherein the first bevel gear 15 is meshed with the second bevel gear 16. Rotating the handle 14 drives the transmission rod 13 to rotate, and through the cooperation of the first bevel gear 15 and the second bevel gear 16, drives the screw rod 12 to rotate. During the rotation of the screw rod 12, the lifting plate 9 is driven to rise and fall, thereby opening or closing the valve plate 6.

[0028] The liquid outlet pipe 3 is provided with a groove 17 on the inner side of the housing. The pressure plate 7 is located in the groove 17. A sealing ring 18 is embedded in the bottom wall of the groove 17. When the valve plate 6 is completely sealed in the liquid outlet pipe 3, the pressure plate 7 is tightly pressed in the groove 17, and the sealing ring 18 prevents liquid from entering the housing 10.

[0029] Example 2

[0030] Based on Example 1, two limit platforms 19 are connected to the top and bottom walls of the liquid outlet pipe 3, respectively. The valve plate 6 is movably disposed between the two limit platforms 19. Sealing strips 20 are provided on opposite sides of the two limit platforms 19. The limit platforms 19 restrict the movement of the valve plate 6, maintaining its linear motion. The sealing strips 20 provide a seal between the valve plate 6 and the limit platforms 19, preventing liquid from leaking.
