2, this device only need observe the numerical value change of vacuum meter can judge the sealing situation at pump up water pipe adapter position, once detect complete, can carry out the dismounting of device at any time.
3, this device in actual applications, and because equipment wherein all adopts thread connecting mode, therefore some of them equipment all can replacing under real work demand carries out different situations or dismounting.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the side view of Fig. 1.
Embodiment
Embodiment 1
The one suction water pipe vacuum checking device basic structure of the present embodiment is as shown in Fig. 1-Fig. 2, comprise suction water pipe 1, water pipe head, detector tube 9, vacuum meter 4, blowdown valve 5, stop valve 6, water tank 7, vacuum pump and respective line, in the present embodiment, water pipe head adopts the connection of water pipe male and water pipe female joint 3, vacuum pump adopts water-ring vacuum pump 8, suction water pipe 1 to be threaded with water pipe female joint 3 detector tube 9 initiating terminal by water pipe male, and detector tube 9 is threaded successively vacuum meter 4, blowdown valve 5, stop valve 6, detector tube 9 end connects the draft tube 11 of water-ring vacuum pump 8, above 7, water tank and water-ring vacuum pump 8 side, the gas outlet 12 of water-ring vacuum pump 8 is by bend pipe access water tank 7, water inlet on water-ring vacuum pump 8 is installed and the water inlet pipe 13 communicated bottom water tank 7.Conveniently device connection and play better sealing effect, adopt between water pipe female joint 3 with detector tube 9 initiating terminal and be connected silk 14, have silk 14 near detector tube 9 end, the bend pipe upper end in access water tank 7 has silk 14; Synchronously carry out, to be connected the draft tube 11 on water-ring vacuum pump 8 at detector tube 9 end by reducing 10, the bend pipe lower end in access water tank 7 connects the gas outlet 12 on water-ring vacuum pump 8 by reducing 10, as shown in Figure 2.
Secondly, in implementation process, detector tube 9 adopts L shape, on the horizontal side of its L shape, vacuum meter 4, blowdown valve 5, stop valve 6 are installed in interval, and the xsect of above-mentioned water tank 7 installs filler 7-3, and it installs overflow pipe 7-1 and water-level gauge 7-2 outside two respectively, water tank 7 side bottom installs the plug 7-4 that discharges water, also install bottom water-ring vacuum pump 8 and to discharge water plug 7-4, as shown in Figure 2, above-mentioned two places discharge water the needs that the setting of plug 7-4 is convenient to select to discharge water certain time.
In addition, the gas outlet 12 on water-ring vacuum pump 8, by bend pipe access water tank 7, plays and is discharged in water tank 7 by gas in suction water pipe 1, also can obtain certain cooling and thermolysis simultaneously in water-ring vacuum pump 8; Because the water inlet of water-ring vacuum pump 8 is installed and the water inlet pipe 13 communicated bottom water tank 7, the water like this by entering in water tank 7 carries out separating air in detector tube 9 and forms stable negative pressure and play good radiating and cooling; Because said apparatus can produce negative pressure, for increasing this device stability, therefore detector tube and respective line all adopt weldless steel tube, meanwhile also require water pipe female joint 3 both sides external to be connected respectively by screw and holder 2, as shown in Figure 1.
Finally, the course of work of the present embodiment: by suction water pipe 1 joint that wherein needs to detect by after water pipe male joint and the connection being arranged on water pipe female joint 3 one end on holder 2, then water pipe female joint 3 other end connects detector tube 9 initiating terminal, due on detector tube 9 successively interval to be threaded vacuum meter 4, blowdown valve 5, stop valve 6, open stop valve 6 like this, fill up water in water tank 7, at this moment the startup water-ring vacuum pump 8 that switches on power gets final product aspiration vacuum, thereafter vacuum meter 4 is observed, when numerical value on vacuum meter 4 is between 0.04 ~ 0.06MPA, now can judge the sealing best results of the joint area aspirating water pipe 1, when numerical value on vacuum meter 4 is within the scope of 0.04 ~ 0.06MPA, just can close stop valve 6 and disconnect water-ring vacuum pump 8, once after detecting, the dismantlement work that respective line is carried out in the first pressure release of blowdown valve 5 again can be opened, one time aspiration procedure just completes.
The utility model is under breakthrough prior art configurations in sum, really to reach institute's wish enhancement effect, and has both had easy to install, good operating stability, the problem such as effectively avoid again the bad pumping for water pump caused of drinking-water pipe sealing difficult.
