Description
Technical field
The utility model is related to technical field of mechanical processing, more particularly to a kind of device for detecting airtightness of corrugated tube.
Background technology
In mechanical seal, due to applied widely, installation is relatively easy, receives the favor of user for sylphon seal.
But since bellows is welded by blocks of wave plate, the quality of welding quality, bellows is airtight after especially welding
The no guarantee of performance, is directly related to the quality of sealing.
Utility model content
In order to solve the above-mentioned technical problem, the utility model discloses a kind of device for detecting airtightness of corrugated tube, pass through one
Kind simple mechanism, the air-tightness of the bellows after convenient detection welding.
Specific technical solution is as follows：
A kind of device for detecting airtightness of corrugated tube, including handle, lead screw, upper plate, limiting plate, pressing plate, connecting rod, bottom plate,
With air source access port；Three threaded holes are uniformly opened up on the upper plate and bottom plate circumference, three connecting rod both ends are screw thread, point
It Dui Ying not screw in the threaded hole of upper plate and bottom plate, and fixation is tightened by nut；The center of the upper plate opens up threaded hole, rotation
Enter lead screw, screw mandrel top connects handle, and lead screw can rotate synchronously under the rotation of handle drive, lead screw bottom end by limiting plate and
Pressing plate is connect by screw with lead screw；By air flue unicom between the connecting rod and bottom plate, and with air source access port unicom, air source
Access port connects pressure gauge.
This method have the advantage that：
Bellows is pressed between pressing plate and bottom plate, is driven lead screw rotation i.e. compressible by rotational handle or is loosened, acts
It is convenient, rapid, improve productivity.When being detected using the present apparatus, air source is connected, introduces the pressure gas for meeting requirement of experiment
Body, pressurize certain time.In pressure maintaining period, notice whether the bellows observed in water leaks, has bubble-free appearance.Testing result
It is high-visible, it is conveniently operated personal observations, record.
Description of the drawings

Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings, but the scope of protection of the utility model is not limited only to
Attached drawing.
Fig. 1 is the structural schematic diagram of the utility model device for detecting airtightness of corrugated tube, and Fig. 2 is the utility model bellows
The floor structure schematic diagram of air-tightness detection device, as shown, device for detecting airtightness of corrugated tube, including handle 1, lead screw 2,
Upper plate 4, limiting plate 5,7 connecting rod 8 of pressing plate, bottom plate 9 and air source access port 10；Three are uniformly opened up on 9 circumference of upper plate 4 and bottom plate
Threaded hole, three 8 both ends of connecting rod are screw thread, corresponding respectively to screw in the threaded hole of upper plate 4 and bottom plate 9, and pass through nut 3
Tighten fixation；The center of upper plate 4 opens up threaded hole, screws in lead screw 2, and 2 top of lead screw connects handle 1, and lead screw 2 can be in handle 1
Rotation drive it is lower rotate synchronously, pressing plate 7 is connect by 2 bottom end of lead screw by limiting plate 5 and screw 6 with lead screw 2；Connecting rod 8 and bottom
By 11 unicom of air flue between plate 9, and with 10 unicom of air source access port, air source access port 10 connect pressure gauge.
In use, the bellows that detects will be needed to be put on bottom plate 9, stirring handle 1 makes lead screw 2 with dynamic pressure plate 7 to moving down
It is dynamic, compress bellows both ends, external gas source pipeline of the connection with pressure gauge.Ready air-leakage test dress is had connected by above-mentioned
It sets entirety to be put into water tank, water level must be more than the upper plane of pressing plate 7.Air source is connected, the pressed gas for meeting requirement of experiment is introduced,
Pressurize certain time.In pressure maintaining period, notice whether the bellows observed in water leaks, has bubble-free appearance.
