Abstract
The utility model discloses a seal joint for plastic pipe and pipe fitting pressure tests, which is designed for aiming at the shortage of the seal joint of which the application number is ZL200420016302. X. The utility model comprises a seal head, a gland, an obconical jaw, a clamping ring and a sealing ring, and the utility model is characterized in that the seal head is formed by welding a heel ring (1), a seal head flange (2) and a seating ring (3) together and is fastened and fixed on a test piece through a set of bolt and nut (8) and the gland (7), wherein the outline of the gland (7) is a flanged disc, an inner ring of the gland is obconical and presses against the obconical jaw (6) of which the upper end face is the clamping ring (5), and the upper end part of the clamping ring (5) contacts and is connected with the lower end part of the seal head seating ring (3) through the sealing ring (4). The sealing ring can deform following the joint by the fastening bolt and nut and is pressed tighter and tighter, so that the prevention of liquid leakage phenomenon of the joint can be thoroughly guaranteed and the utility model is more suitable for large caliber test pieces of which the diameter of the pipe ranges from 63MM to 630MM.
Description
Technical field: the utility model relates to a kind of plastic tube, pipe fitting hydrostatic test equipment, is a kind of SEALING FITTING of test specimen specifically.
Background technique: at present, implement FLUID TRANSPORTATION thermoplastic plastic pipe internal pressure-resistant test method, the SEALING FITTING of one of its equipment, mostly adopt A type or Type B structural type in the GB/T6111-2003 standard, the major defect of this structural type is poorly sealed, and the leak of liquid phenomenon often takes place in the test.In order to overcome above-mentioned defective, Chinese patent ZL 200420016302.X discloses a kind of " plastic tube, pipe fitting pressure test SEALING FITTING ", this joint has overcome aforementioned disadvantages, but because it adopts and is threaded, therefore only be applicable to tubing, the pipe fitting of osculum warp, then powerless for bigbore tubing, pipe fitting.
The model utility content: the purpose of this utility model is at the problems referred to above, a kind of large-bore plastics tubing is provided, pipe fitting pressure test SEALING FITTING, it is realized by following technical solution: a kind of large-bore plastics tubing, pipe fitting pressure test SEALING FITTING, comprise end socket, gland, the tapered jaw of rounding, trim ring and seal ring, it is characterized in that: end socket is by fixing collar, cover flange and positioning ring welding constitute, and be fastened on the test specimen by bolt and nut and gland, wherein, the profile of gland is a flange plate, its inner ring is inverted cone-shaped, push down the tapered jaw of rounding, the upper-end surface of the tapered jaw of rounding is a trim ring, and the upper end portion of trim ring touches mutually by the underpart of seal ring with the end socket positioning ring.Compared with prior art, the utility model is connected with bolt and nut by adopting flange, can guarantee fully that not only joint the leak of liquid phenomenon can not take place, and enlarge the application area of equipment, it is particularly useful for the heavy caliber test specimen of caliber in the 63mm-630mm scope.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Embodiment: the utility model is elaborated below in conjunction with accompanying drawing.
As shown in the figure, the large-bore plastics tubing that the utility model provides, pipe fitting pressure test SEALING FITTING, comprise end socket, gland, the tapered jaw of rounding, trim ring and seal ring, it is characterized in that: end socket is made of 3 welding of fixing collar 1 cover flange 2 positioning rings, and be fastened on the test specimen by bolt and nut 8 and gland 7, wherein, the profile of gland 7 is a flange plate, its inner ring is inverted cone-shaped, push down the tapered jaw 6 of rounding, the upper-end surface of the tapered jaw 6 of rounding is trim rings 5, and the upper end portion of trim ring 5 touches mutually by the underpart of seal ring 4 with end socket positioning ring 3.By the clamping bolt nut, it is tight more that the seal ring 4 is here pressed more, and evidence, and the sealing effect of big more this joint of interior pressure of test specimen is good more.
Claims (1)
1, a kind of large-bore plastics tubing, pipe fitting pressure test SEALING FITTING, comprise end socket, gland, the tapered jaw of rounding, trim ring and seal ring, it is characterized in that: end socket is made of fixing collar (1) cover flange (2) positioning ring (3) welding, and be fastened on the test specimen by bolt and nut (8) and gland (7), wherein, the profile of gland (7) is a flange plate, its inner ring is inverted cone-shaped, push down the tapered jaw of rounding (6), the upper-end surface of the tapered jaw of rounding (6) is trim ring (5), and the upper end portion of trim ring (5) touches mutually by the underpart of seal ring (4) with end socket positioning ring (3).
