Abstract
The utility model discloses a sealing and fastening structure of a pressure test cylinder, which comprises an upper flange, a lower flange, a clamp hoop and a lantern ring, wherein the upper flange is vertically abutted with the lower flange, the outer sides of the upper flange and the lower flange are respectively provided with latches, the clamp hoop is in a ring shape and consists of two or more arc-shaped sub clamp hoops abutted with each other and uniformly distributed circumferentially, the inner side of the clamp hoop is provided with two groups of latches, the two groups of latches are respectively meshed with the latches of the upper flange and the lower flange, the lantern ring sleeves the clamp hoop, and a sealing ring is arranged between the upper flange and the lower flange. The utility model has simple structure and is convenient to assemble and disassemble, a cylinder cap of the pressure test cylinder is arranged via the fastening connection among the clamp hoop, the upper flange and the lower flange, and the dimension of the flange section of the pressure test device can be greatly reduced, so the dimension of the working section of the pressure test device can be increased under the existing processing condition.
Description
Technical field
The utility model relates to a kind of sealing fastening structure, relates in particular to the sealing fastening structure of pressure test tube.
Background technology
For the ease of test specimen is installed, the pressure test tube need be provided with the big opening of full size, the sealing of opening and the fastening form of flanges that is generally, upper and lower flange side is straight, and do not have between clip and be in contact with one another, the fastening of device only realize by upper and lower two surface of contact, thereby stress level height, the dismounting inconvenience of structure during pressure experimental device work.For working pressure and the bigger pressure experimental device of test yardstick, to bring a series of difficult problems if continue to adopt this scheme: for reducing flange place stress level, must use the large scale solid forging, the large scale solid forging is with high costs, and has technical risk; Upper and lower two surface of contact place friction force are huge, need large-scale hydraulic mechanism just can finish the unlatching of pressure experimental device with closed.
Summary of the invention
The utility model provides a kind of sealing fastening structure of pressure test tube at the above-mentioned deficiency of prior art, have flange section yardstick little, be convenient to the characteristics installing and dismantle.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The utility model comprises upper flange, lower flange, ring-type clip and the collar, upper flange and lower flange be butt up and down, the upper flange and the lower flange outside are provided with latch respectively, clip is made of two or above circumferentially uniform circular-arc minute mutual butt of clip, the clip inboard is provided with two groups of latches, these two groups of latches respectively with the engagement of the latch of upper flange and lower flange, collar fit clip; Between upper flange, the lower flange O-ring seal is set
Technique effect of the present utility model is:
1. the yardstick that significantly reduces pressure experimental device flange section can be arranged, thereby under existing processing conditions, increase the active section yardstick of pressure experimental device.
2. the friction between flange and clip is less, is convenient to dress, tears open.
Description of drawings
Fig. 1 is a structure cross-sectional schematic of the present utility model.
Embodiment
See Fig. 1, the utility model comprises that the outside is provided with the upper flange 3 and the lower flange 7 of latch 2 respectively, is provided with O-ring seal 6 between upper flange 3 and the lower flange 7.Clip 4 is a ring-type, constitute by two or more than two circumferential uniform circular-arc minute mutual butt of clip (not drawing among the figure), be convenient to dismounting, clip 4 inboards are provided with two groups of latches 1 that match with the latch 2 of upper flange 3, lower flange 7 respectively, thereby latch 1 and latch 2 engagements realize clips 4, upper flange 3, lower flange 7 threes being fastenedly connected each other.
When the utility model uses, lower flange 7 and pressure test cylindrical shell (not drawing among the figure) welding, upper flange 3 is connected with tube cap (not drawing among the figure), the tube cap is installed on the pressure test cylindrical shell by clip 4, upper flange 3, lower flange 7 threes being fastenedly connected each other, O-ring seal 6 can guarantee the positiver sealing of cylindrical shell and tube cap, the collar 5 is linked in the outside of clip 4, guarantees to be fastened securely.
Claims (2)
1. the sealing fastening structure of pressure test tube, comprise upper flange (3), lower flange (7), ring-type clip (4) and the collar (5), upper flange (3) and lower flange (7) be butt up and down, it is characterized in that upper flange (3) and lower flange (7) outside is provided with latch (2) respectively, clip (4) is made of two or above circumferentially uniform circular-arc minute mutual butt of clip, clip (4) inboard is provided with two groups of latches (1), these two groups of latches (1) respectively with the engagement of the latch (2) of upper flange (3) and lower flange (7), the collar (5) fit clip (4).
