Description
Technical field
The utility model relates to a kind of pressure testing device.
Background technology
At present, suppress aerating device and be widely used, in use, whether usual needs inspection leaks gas, when suppressing, in prior art,, easily there is the phenomenon that plate ejects in its pressure testing process, there is larger potential safety hazard in the pressure testing mode of usual employing board in adapter exterior boss.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of pressure testing device rational in infrastructure, thus improves dependability, and security is high.
The technical scheme that the utility model adopts is as follows:
A kind of pressure testing device, comprise adapter, the top of described adapter is fixed with the first packing ring, be positioned at nozzle interior and fix second packing ring parallel with the first packing ring, between described first packing ring and the second packing ring, rubber is installed, the inside face being positioned at adapter is also provided with boss, and described boss contacts with rubber; Screw bolt passes second packing ring, rubber and the first packing ring, and at the top of the first packing ring by nut lock, described bolt head is by O-ring seal jointing; The through hole of inflating is had in the middle part of described bolt.
The beneficial effects of the utility model are as follows:
The utility model is compact, reasonable, and manufacture and installation is convenient, and its usage safety performance is high, can effectively avoid because of pressure excessive time, pressure testing device ejects the potential safety hazard of hurting sb.'s feelings, and its pressure testing is convenient and swift, saving man-hour, and work efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, joint; 2, O-ring seal; 3, bolt; 4, through hole; 5, nut; 6, the first packing ring; 7, rubber; 8, boss; 9, take over; 10, the second packing ring.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the pressure testing device of the present embodiment, comprise adapter 9, the top of adapter 9 is fixed with the first packing ring 6, be positioned at fixing second packing ring 10 parallel with the first packing ring 6 in adapter 9 inside, be provided with rubber 7 between first packing ring 6 and the second packing ring 10, the inside face being positioned at adapter 9 is also provided with boss 8, and boss 8 contacts with rubber 7; Bolt 3 successively through the second packing ring 10, rubber 7 and the first packing ring 6, and is locked by nut 5 at the top of the first packing ring 6, and bolt 3 head is by O-ring seal 2 jointing 1; The through hole 4 of inflating is had in the middle part of bolt 3.
In actual use procedure, in the through hole 4 of bolt 3, squeeze into gas, under force, bolt 3 upwardly, makes rubber 7 produce compression, is stuck on boss 8 after compression, effectively prevents rubber 7 from the phenomenon of sliding occurring.Pressure testing is convenient.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
