[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Figure 1 and Figure 2 A two-position six-way valve component is shown, comprising a valve body 1, on which a plurality of groups of valve holes 2 are arranged, and a solenoid valve 3 for switching the plurality of groups of valve holes 2 is fixed at the end of the valve body 1, six valve holes 2 are arranged, and every two valve holes 2 form a group, and three groups of valve holes 2 are distributed on three sides of the valve body 1.

[0025] Cooperate Figure 3 , Figure 4 and Figure 5 As shown, a mounting groove 4 is provided on the valve body 1 at a position corresponding to each group of the valve holes 2, a detection tube 5 connected to a channel of a group of the valve holes 2 is fixed in the mounting groove 4, the detection tube 5 is connected to an airtight tube 6, and in specific implementation, a docking tube 601 is fixed to the end of the airtight tube 6, the docking tube 601 and the detection tube 5 are threadedly connected, and the valve body 1 and the airtight tube 6 are connected, and a sealing ring 602 is fixed to the end of the airtight tube 6 around the docking tube 601, and the sealing ring 602 can ensure the airtightness between the valve body 1 and the airtight tube 6.

[0026] A piston 8 is arranged in the airtight tube 6, and a warning window 9 for displaying the position of the piston 8 is arranged on the side of the airtight tube 6. The warning window 9 is located in a strip window arranged along the airtight tube 6, and a scale line for displaying the position of the piston 8 is arranged on the warning window 9. When an airtight problem occurs in the channel in the valve body 1, it will cause the pressure in the valve body 1 to change, and the piston 8 will slide in the airtight tube 6, so that the staff can quickly find the airtight problem through the warning window 9, which is conducive to quick troubleshooting and easy to use.

[0027] In addition, a reminder device 7 is fixed to one end of the airtight tube 6 away from the detection tube 5, and a warning device 701 and a control switch 702 are installed on the reminder device 7. In this embodiment, the warning device 701 is an LED warning light, and in other embodiments, the warning device 701 can also be a buzzer.

[0028] Among them, the alarm 701 is arranged on the side of the reminding device 7, the control switch 702 is fixed at the end of the reminding device 7 and extends into the airtight tube 6, and an abutment column 801 is fixed in the middle of the piston 8, and the abutment column 801 abuts and cooperates with the control switch 702, so that when the pressure in the valve body 1 is too high, the abutment column 801 will abut the control switch 702 to control the alarm 701 to give an alarm.

[0029] The practical working principle of the present invention is as follows: when the two-position six-way valve is in use, the channel formed by the multiple groups of valve holes 2 on the valve body 1 can be switched by the solenoid valve 3 to allow the medium to pass through, and the airtight tube 6 at the corresponding position on the valve body 1 is connected through the channel formed by the corresponding group of valve holes 2, so that when the airtightness of the channel in the valve body 1 is abnormal and the pressure changes, the piston 8 can be driven by the changing pressure to move to a certain extent in the airtight tube 6, so that the staff can quickly judge the airtightness problem of the channel through the warning window 9, which is beneficial for the staff to quickly discover the airtightness problem and has a good use effect.

[0030] At the same time, when the internal pressure of the valve body 1 is too high, the piston 8 is pushed to move by its internal pressure, and the piston 8 will drive the abutment column 801 to abut the control switch 702, and then control the alarm 701 to start to warn the staff. It can avoid the problem of excessive pressure to a certain extent. Therefore, it has a certain explosion-proof effect and is safer to use.

[0031] In summary, the two-position six-way valve can not only facilitate the staff to quickly discover the airtightness problem and conduct investigation and positioning, but also has a certain explosion-proof effect, is easy to use and has a high safety factor.
