DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] As Figures 1 - 3 shown, a multi-channel purging device that can be quickly disconnected includes a main body 1 of the purging device. A switching component 2 is arranged inside the main body 1 of the purging device. The switching component 2 includes a purging valve block 10. By respectively ventilating the left vertical plate 9 or the right vertical plate 8 through the first intake joint 6 and the second intake joint 7, the working state of the purging valve block 10 inside the main body 1 of the purging device can be switched. When purging operation is carried out, the right vertical plate 8 is ventilated through the second intake joint 7 to push the sealing piston column 11 inside the right vertical plate 8. The sealing piston column 11 at the right vertical plate 8 pushes the purging valve block 10 to slide towards the left vertical plate 9 inside the main body 1 of the purging device. At this time, the purging hole 14 on the purging valve block 10 is communicated with the quick-change joint 4 on the upper panel 3, and the purging sub-hole 12 is communicated with the purging joint 5 through the through-hole opened on the upper panel 3, so that the purging air path is penetrated, and the device is in the purging state.
[0024] After the purging operation is completed, air is introduced into the left vertical plate 9 through the first air inlet joint 6 to push the sealing piston column 11 inside the left vertical plate 9. The sealing piston column 11 at the left vertical plate 9 pushes the purging valve block 10 to slide towards the right vertical plate 8 inside the purging device main body 1. At this time, the through hole 13 on the purging valve block 10 is connected to the pressure guiding pipe 16 on the lower panel 15. At this moment, the quick-change joint 4 on the upper panel 3, the through hole 13 on the purging valve block 10, and the pressure guiding pipe 16 on the lower panel 15 are all connected, so that the operation air path is unblocked and the device enters the operating state. At this time, the scanning pressure test can be carried out without removing this device. This device uses the connection between the quick-change joint 4 and the air pipe to replace the connection between the traditional pressure guiding pipe 16 and the air pipe, which plays the role of quick disconnection and quick replacement, reduces the operation steps and the risk of misinstallation. By moving the purging valve block 10 left and right, the on-off of the purging joint 5 on the upper panel 3 and the pressure guiding pipe 16 on the lower panel 15 is realized, so as to achieve the conversion between the operation-purging mode, which is convenient for the staff to quickly switch the working state of the device and is more convenient to use.
[0025] As Figures 2 - 4 shown, the upper panel 3 is detachably installed at the top of the purging device main body 1. Through holes are symmetrically opened at the bottom of the upper panel 3. The bottom of the purging joint 5 is connected to the through holes opened on the upper panel 3. The through holes opened on the upper panel 3 correspond to the purging sub-holes 12. When the device is performing the purging operation, the air inlet at the purging joint 5 is transformed into a double channel under the through holes of the upper panel 3, and then the air is sent to the purging sub-holes 12 with the same double channel through the through holes of the upper panel 3. The two purging sub-holes 12 on the purging valve block 10 ventilate the purging holes 14. Compared with the traditional single-channel purging, the multi-channel purging has the advantages of larger purging flow rate, smaller pressure loss, higher efficiency, and more thorough cleaning. When the total input pressure remains unchanged, the pressure in each channel of the double channel is close to the traditional single-channel inlet pressure, achieving the effect of 1+1>2, with higher purging efficiency and more thorough cleaning, thus ensuring the test accuracy. Compared with the pressure scanning valves with purging functions on the market, by increasing the purging channels, the gas flow rate in the channels is increased, the pressure loss is reduced, the discharged pressure is greater, and the purging is more thorough.
[0026] Working principle
[0027] It should be noted that the present utility model is a multi-channel purging device that can be quickly disconnected. When in use, first, air is introduced into the left vertical plate 9 or the right vertical plate 8 through the first air inlet joint 6 and the second air inlet joint 7 respectively to switch the working state of the purging valve block 10 in the purging device main body 1. When it is necessary to perform a purging operation on the purging valve block 10, air is introduced into the right vertical plate 8 through the second air inlet joint 7 to push the sealing piston column 11 in the right vertical plate 8. The sealing piston column 11 at the right vertical plate 8 pushes the purging valve block 10 to slide towards the left vertical plate 9 in the purging device main body 1. At this time, the purging hole 14 on the purging valve block 10 is communicated with the quick-change joint 4 on the upper panel 3, and the purging sub-hole 12 is communicated with the purging joint 5 through the through hole opened on the upper panel 3, so that the purging air path is unblocked, and the device enters the purging state. At this time, air is introduced from the purging joint 5, and the air inlet at the purging joint 5 is converted into a dual-channel under the through hole of the upper panel 3, and then the air is sent to the purging sub-hole 12 of the same dual-channel through the through hole of the upper panel 3. The two purging sub-holes 12 on the purging valve block 10 ventilate the purging hole 14 to achieve the purpose of multi-channel purging.
[0028] After the purging operation is completed, air is introduced into the left vertical plate 9 through the first air inlet joint 6 to push the sealing piston column 11 in the left vertical plate 9. The sealing piston column 11 at the left vertical plate 9 pushes the purging valve block 10 to slide towards the right vertical plate 8 in the purging device main body 1. At this time, the through hole 13 on the purging valve block 10 is communicated with the pressure guiding pipe 16 on the lower panel 15. At this time, the quick-change joint 4 on the upper panel 3, the through hole 13 on the purging valve block 10, and the pressure guiding pipe 16 on the lower panel 15 are all communicated, so that the operation air path is unblocked, and the device enters the operation state. At this time, without removing the device, a scanning pressure test can be performed to achieve the purpose of convenient switching of the operation state.
