Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, a kind of sniffer, it comprises a tee pipe fitting 1, admission gear that is connected with a mouth of pipe 11 of this tee pipe fitting 12, an exhaust gear 3 that is connected with another mouth of pipe 12 of this tee pipe fitting 1 and a joint mechanism 4 that is connected with this tee pipe fitting 1 last mouth of pipe 13.
This exhaust gear 3 comprises a nozzle holder 31 that is threaded with a mouth of pipe 12 of this tee pipe fitting 1 and an exhausr port 32 that is threaded with this nozzle holder 31.
This admission gear 2 comprises an adjusting spiral shell seat that is threaded with another mouth of pipe 11 of this tee pipe fitting 1 21, nozzle that is connected with these adjusting spiral shell seat 21 threaded one ends 22, ball valve joint that is threaded with these adjusting spiral shell seat 21 other ends 23, a ball valve 24 that is threaded with this ball valve joint 23 and a blast connection 25 that is threaded with this ball valve 24, be provided with a clamp nut 211 outside this adjusting spiral shell seat 21, it is nylon washers that this adjusting spiral shell seat 21 and 23 of this ball valve joints are provided with a nylon second packing ring 212, the second packing rings 212.
This joint mechanism 4 comprises a hole connector 41 that is threaded with this tee pipe fitting 1 last mouth of pipe 13, a plurality of bolt assembly 42 on this hole connector 41, first packing ring 43 and pad 44 that is pressed under this hole connector 41 that places in this hole connector 41 of being located at, this first packing ring 43 is nylon washers, and this pad 44 is cellular rubber pads.
During concrete the application, by joint mechanism 4, sniffer is installed on the plexiglass tent 5, a vacuum meter 6 is installed on plexiglass tent 5, vacuum meter 6 get and installs with plexiglass tent 5 bolted vacuum meter joints by one, and airduct of blast connection 25 connections of sniffer is when ball valve 24 is opened, air-flow flows into admission gear 2 from airduct, discharge then by tee pipe fitting 1, and from exhaust gear 3, in this process, because air-flow has certain speed, the air that it can take away plexiglass tent 5 inside makes to become vacuum state gradually in the cloche 5, so, tensimeter then shows the negative pressure in the cloche 5, when reaching the vacuum detecting standard, pressure can detect observation, in addition, and by adjusting to ball valve 24, realize the adjusting of sniffer vacuum pressure, make detecting operation easier.
