Technical Field

[0001] The utility model relates to the technical field of battery baking process production, in particular to a six-way flow valve. Background Art

[0002] A six-way flow valve is a valve used in a fluid control system and is widely used in various systems such as heating and refrigeration. Its main function is to control the flow direction and flow rate of the fluid by changing the connection mode of the internal channels, so as to realize the switching or mixing between multiple loops in the system.

[0003] After retrieval, the prior art discloses a six-way valve of a magnetic mass spectrometer. The six-way valve includes a six-way valve body, an electromagnetic valve core and a flow regulating valve mechanism. A flow regulating valve installation port is arranged in the middle of one side of the six-way valve body. Eight sample injection ports are arranged on both sides of the six-way valve body. Seven electromagnetic valve core installation ports are arranged at the edge of the six-way valve body and in the middle of the other side of the six-way valve body. A quantitative sample outlet is arranged at the top of the six-way valve body. A backflush cold trap connection port is arranged at the bottom of one side of the six-way valve body. An installation bracket is arranged at the bottom end of the six-way valve body. Seven electromagnetic valve cores are arranged at the edge and in the middle of one side of the six-way valve body. A flow regulating valve mechanism is installed in the middle of the other side of the six-way valve body. Among them, the flow regulating valve mechanism includes a conical sealing needle, a fluororubber sealing ring, a fixing nut and a driving mechanism. The conical sealing needle is inserted into the flow regulating valve installation port. A fluororubber sealing ring is arranged at one end of the conical sealing needle. A driving mechanism is installed at one end of the conical sealing needle through a fixing nut. The flow regulating valve device in this scheme effectively solves the regulation problem in the quantitative sample injection process of the sample injection system and can avoid the instability caused by traditional manual control. However, a similar flow regulating device can still only control all channels at one time and cannot achieve single-channel control, so the applicable range is relatively narrow. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a six-way flow valve to overcome the defects of the prior art that single-channel control cannot be achieved and the applicable range is relatively narrow.

[0005] The purpose of the utility model can be realized by the following technical solutions:

[0006] The utility model provides a six-way flow valve, which includes a valve seat assembly, a valve core, a main pipeline, a branch pipeline, a flow regulating mechanism and a motor. One end of the main pipeline is connected to one end of the branch pipeline. The other end of the main pipeline and the other end of the branch pipeline are respectively connected to the valve seat assembly. The valve seat assembly is connected to the valve core. The flow regulating mechanism is connected to the branch pipeline. One end of the motor is drivingly connected to the valve core, and the other end is located in the area surrounded by the main pipeline, the branch pipeline and the valve seat assembly.

[0007] As a preferred technical solution, the valve seat assembly includes a first valve seat, a second valve seat and a third valve seat for supporting the valve core. The first valve seat is located on the side of the valve core away from the motor, the third valve seat is located on the side of the valve core close to the motor, and the second valve seat is located between the first valve seat and the third valve seat.

[0008] As a preferred technical solution, a first sealing element is provided between the first valve seat and the second valve seat, and a second sealing element is provided between the second valve seat and the third valve seat.

[0010] As a preferred technical solution, the motor is a stepper motor.

[0011] As a preferred technical solution, the motor is a servo motor.

[0012] As a preferred technical solution, the flow rate regulating mechanism includes an electric flow valve.

[0013] As a preferred technical solution, the six-way flow valve further includes a motor plate and a column. The motor is installed on the motor plate, and the motor plate is installed on the column.

[0014] As a preferred technical solution, the six-way flow valve further includes a coupling. One end of the coupling is connected to the output shaft of the motor, and the other end is connected to the valve core.

[0015] As a preferred technical solution, the six-way flow valve further includes a shaft seal, and the shaft seal is installed between the valve core and the valve seat.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] 1. At present, there is no liquid multi-way flow valve on the market. To achieve multi-way flow control, multiple straight-through flow valves need to be used in parallel, which occupies a relatively large space. In the six-way flow valve provided by the present utility model, one end of the motor is drivingly connected to the valve core, and the other end is located in the area surrounded by the main pipeline, the branch pipeline and the valve seat assembly. The motor turntable type is used to control the flow rate of each channel. Compared with direct pneumatic control, it has a smaller volume, a more compact structure, and occupies less space;

[0018] 2. The valve core of the present utility model is driven by a motor, with high positioning accuracy. At the same time, the motor drives the valve core to rotate, and it can be arbitrarily switched to the channel that needs to adjust the flow rate. The adjustment is flexible, and single-channel control can be achieved, with a wider scope of application;

[0019] 3. The flow regulating mechanism of the present utility model can adopt an electric flow valve. Through the control of the electric flow valve, the flow can be automatically adjusted according to requirements, effectively improving the scene adaptability of the six-way flow valve.

[0026] Embodiment 1

[0027] Such as Figure 1As shown in the figure, this embodiment provides a six-way flow valve, which includes a valve seat assembly, a valve core 1, a main pipeline 2, a branch pipeline 3, a flow regulating mechanism 4, and a motor 5. One end of the main pipeline 2 is connected to one end of the branch pipeline 3, and the other end of the main pipeline 2 and the other end of the branch pipeline 3 are respectively connected to the valve seat assembly. The valve seat assembly is connected to the valve core 1, the flow regulating mechanism 4 is connected to the branch pipeline 3, one end of the motor 5 is drivingly connected to the valve core 1, and the other end is located in the area surrounded by the main pipeline 2, the branch pipeline 3, and the valve seat assembly. Among them, the valve seat assembly is the fixed seat of the six-way flow valve, the valve core 1 is used to adjust the flow rate of one of the 6 channels, the main pipeline 2 is the water inlet, the branch pipeline 3 is used to adjust the branch water flow rate, and the motor 5 is used to drive the valve core 1 to rotate to control the water flow rate of a certain channel.

[0028] The valve seat assembly includes a first valve seat, a second valve seat, and a third valve seat, which are used to support the valve core 1. Figure 1 Viewed from the [direction not specified in the original text], the first valve seat is the front valve seat 61, the second valve seat is the middle valve seat 62, and the third valve seat is the rear valve seat 63. One side of the valve core 1 away from the motor 5 is connected to the front valve seat 61, and one side close to the motor 5 is connected to the rear valve seat 63. And a shaft seal 7 is installed between the rear valve seat 63 and the side of the valve core 1 close to the motor 5. The shaft seal 7 is used to seal the interface between the valve seat assembly and the valve core 1 to prevent fluid leakage. The front valve seat 61 is located on the side of the valve core 1 away from the motor 5, the rear valve seat 63 is located on the side of the valve core 1 close to the motor 5, and the middle valve seat 62 is located between the front valve seat 61 and the rear valve seat 63. The valve seat assembly also includes a first sealing element and a second sealing element. Both sealing elements are sealing gaskets, which are used to seal the front, middle, and rear valve seats into a whole to prevent water leakage. The first sealing element, that is, the front valve seat gasket 64, is arranged between the front valve seat 61 and the middle valve seat 62, and the second sealing element, that is, the rear valve seat gasket 65, is arranged between the middle valve seat 62 and the rear valve seat 63. Thus, the front valve seat 61, the middle valve seat 62, the rear valve seat 63, and the front valve seat gasket 64 and the rear valve seat gasket 65 together form a sealed valve seat assembly, which can effectively avoid water leakage.

[0029] The inlet end of the main pipeline 2 serves as the water inlet and is connected to the inlet end of the branch pipeline 3. The other end of the main pipeline 2 is connected to the rear valve seat 63. The water flow in the main pipeline 2 flows into the branch pipeline 3 and then into the rear valve seat 63.

[0030] The inlet end of the branch pipeline 3 is connected to the main pipeline 2, the other end is connected to the middle valve seat 62, and a flow regulating mechanism 4 is also arranged on the pipeline of the branch pipeline 3. In this embodiment, the flow regulating mechanism 4 uses an electric flow valve. Water enters from the main pipeline 2 into the branch pipeline 3, and the electric flow valve adjusts the flow rate and then flows into the middle valve seat 62.

[0031] In this embodiment, the motor 5 is a stepper motor. The stepper motor is connected to the valve core 1 through a column, a motor plate 8, and a coupling 9, and drives the valve core 1 to rotate into the 6-channel. The motor plate 8 is installed on the column, and the column supports the motor plate 8. The stepper motor is installed on the motor plate 8, and its output shaft passes through the motor plate 8 and is connected to one end of the coupling 9. The other end of the coupling 9 is connected to the side of the valve core 1 close to the stepper motor.

[0032] It can be seen that in the six-way flow valve provided in this embodiment, the valve core 1 is connected to the front valve seat 61, the rear valve seat 63, the coupling 9, and the stepper motor. Whichever of the 6 channels needs to adjust the flow rate, the valve core 1 rotates to that channel.

[0033] As Figure 2 shown, the complete process of adjusting the flow rate of the No. 1 channel is as follows: The electric flow valve automatically adjusts the required flow rate, which flows through the middle valve seat 62 into the channel of the valve core 1. The valve core 1 is driven by the stepper motor to rotate to the position of the No. 1 channel, making it communicate with the No. 1 channel, and the remaining 5 channels communicate with the main pipeline 2.

[0034] Embodiment 2

[0035] This embodiment provides another six-way flow valve, which has basically the same structure as the six-way flow valve provided in Embodiment 1. The difference between the two is that the motor 5 in this embodiment is a servo motor. Therefore, in the six-way flow valve provided in this embodiment, the valve core 1 is connected to the front valve seat 61, the rear valve seat 63, the coupling 9, and the servo motor. Whichever of the 6 channels needs to adjust the flow rate, the valve core 1 rotates to that channel. The remaining structure and the channel switching method are the same as those in Embodiment 1 and will not be described in detail here.

[0036] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning, or limited experiments based on the concept of the present invention on the basis of the prior art should be within the protection scope determined by the claims.
