Abstract
The utility model relates to a novel flange formula pipe connection device, its characterized in that: it still includes a locking ring, the locking ring whole be the toper, be equipped with in the middle of its ring body that locking is closed to be reserved mouthful, set up between the tube end platform that the flange gland was held with flange joint, compress tightly the neck platform what flange center opening was equipped with the downward bulge, the neck platform that compresses tightly establish the top surface at the locking ring. The advantage that this patent structure is the biggest is simple structure, safe and reliable. Pipe -line system is the oscillation generation under water impact, so often make other can loosen gradually like screw thread and so on connected mode to take off, this problem has thoroughly been solved to the flange structure.
Description
Technical field
This utility model relates to a kind of pipe connecting device, is related specifically to the pipe connecting device using flange to be attached.
Background technology
In prior art, connection between the connection of pipeline enclosure particularly plastic conduit, most employings are threaded, but this threaded existence vibrates the problem got loose, as tubing produces vibration under water impact, so often making other can gradually get loose such as screw thread etc. connected mode；Now with in technology, also have and individually use Flange joint, but owing to the contractility of plastic tube is often under the change of temperature, naturally shrinks, also can produce the phenomenon that gets loose.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Novel flange type assembling pipe joint, solves in plastic tube Flange joint, solves long-time use, due to water pressure fluctuations, produces water flow fluctuation, thus produces the problem that connector loosens.
For completing above-mentioned utility model purpose, this utility model is achieved in that a kind of Novel flange type assembling pipe joint, it includes inserting tubing, flanged ends and flange gland, flanged ends is one-body molded with pipe fitting, described insertion tubing is inserted in pipe fitting, and flange gland is enclosed within insertion tubing and flanged ends corresponding matching；It is characterized in that: it also includes that a retaining ring, described retaining ring are integrally conical, in the middle of its ring body, be provided with locking Guan Bi reserved opening, be arranged between the birdsmouth platform of flange gland and flanged ends；It is provided with downwardly projecting compression neck platform at flange center's opening；The described neck platform that compresses is located at the end face of retaining ring.This patent uses the pressure that locking is downward, during adjunction, is tapered opening design owing to using, and therefore, in compaction process, can increase along with pressure and hold insertion tubing tightly；Insert tubing such that it is able to firmly pin, make pipe fitting be difficult to loosen.
Technique scheme is improved further, between flange bellmouth platform and retaining ring, is additionally provided with sealing ring.
Being improved further technique scheme, described flange gland central opening passes for inserting tubing, and periphery is engaging lug, which is provided with bolt penetration hole；It is provided with downwardly projecting compression neck platform at flange center's opening.
Technique scheme is improved further, is uniform-distribution with many ribs at retaining ring periphery.
Being improved further technique scheme, the periphery of described flanged ends is provided with the bolt hole docked with flange gland；Center sets for inserting the perforation that tubing passes；Inwall is tapered, matches with retaining ring；At the end of inwall, it is provided with the flange bellmouth platform placed for sealing ring.
The advantage of this patent structure maximum is simple in construction, safe and reliable.Tubing produces vibration under water impact, so often making other can gradually get loose such as screw thread etc. connected mode, flange arrangement thoroughly solves this problem.

Detailed description of the invention
In order to allow those skilled in the art be understood more readily from the construction features of this patent, below we combine accompanying drawing and are further described.
As it can be seen, a kind of Novel flange type assembling pipe joint, it is by inserting tubing, and flanged ends, flange gland, retaining ring sealing ring is constituted；Above-mentioned parts, all use plastic material to make outside attached sealing ring；This patent is also only applicable to plastic pipe and connects.Flanged ends is one-body molded with pipe fitting, inserts tubing and is inserted in pipe fitting, and flange gland is enclosed within insertion tubing and flanged ends corresponding matching；Retaining ring is arranged between the birdsmouth platform of flange gland and flanged ends.
Above-mentioned middle flange gland central opening passes for inserting tubing, and periphery is engaging lug, which is provided with bolt penetration hole；At flange center's opening edge along being provided with downwardly projecting compression neck platform.
The periphery of flanged ends is provided with the bolt hole docked with flange gland；Center sets for inserting the perforation that tubing passes；Inwall is tapered, matches with retaining ring；At the end of inwall, it is provided with the flange bellmouth platform placed for sealing ring.
Retaining ring is integrally conical, and is provided with locking Guan Bi reserved opening in the middle of its ring body, and retaining ring periphery is uniform-distribution with many ribs.
During installation, flange gland 1, retaining ring 2, O-ring seal 3 are respectively fitted over the one end inserting tubing 5, then by the bellmouth inserting tubing 5 and inserting pipe fitting 4, with bolt, flange gland 1 are connected with pipe fitting 4.The backward lower compression O-ring seal 3 of retaining ring 2 pressurized, seals, and simultaneously by the radial force effect on cylindrical inclined-plane, holds insertion tubing 5 tightly, plays fixing effect.
The advantage of this structure maximum is simple in construction, safe and reliable.Tubing produces vibration under water impact, so often making other can gradually get loose such as screw thread etc. connected mode, flange arrangement thoroughly solves this problem.
