Abstract
The utility model relates to a V-shaped pipe joint, belonging to the class of the mechanical engineering. The utility model aims at replacing the process of the pipeline threading, and obtains the pipe joint with reliable work. The V-shaped pipe joint has enough large bondability and reserve. When in use, the V-shaped ring is embedded in a pipe wall to realize the functions of connection and seal. The V-shaped ring can be made of spring steel, alloy steel, quality carbon steel, tool steel, etc., the strength and the hardness of the V-shaped ring are selected according to the principle that the material is slightly higher than the pipe material. The utility model can apply to various interfaces of the valves of the pipeline apparatuses, various pipe fittings, etc.
Description
The utility model belongs to mechanical engineering, is to disclose a kind of resiliently deformable of circle of utilizing itself to block the Quick Connect Kit that pipeline is realized pipeline.
In order to break away from the pipeline mantle fiber technology of cumbersome heaviness.A large amount of evaporating, emitting, dripping or leaking of liquid or gas phenomenons that exist in the various pipelines of thorough low solution, the engineers and technicians of all trades and professions have carried out unremitting effort, and have obtained certain achievement.But limit for a certain reason, existing achievement all can not replace the pipeline mantle fiber to connect technology fully.88220052, No. 6 patents for example, though the mantle fiber technology when waived pipeline links, but still on structure and performance, have some shortcomings.Mainly containing the seal ring volume greatly wears out, creeps easily and follow the string and leak easy damaged seal ring when gland nut screws.And the capsule power of holding that only relies on the friction between seal ring and tube wall to obtain is insecure; When joint bears moment of flexure, during shaking force, the silk between main body and the gland nut and will bear very disadvantageous power causes loosening easily and leaking is appearred in the extruding force uneven distribution of seal ring.The purpose of this utility model provides a kind of nothing leakage, reliable operation, can bear the moment of flexure shaking force, saves stuffing box packing, does not need the quick connecting pipe road joint of mantle fiber.
The utility model is achieved in that by known a kind of pipe coupling to be made up of main body gland nut, seal ring, feature of the present utility model is to sandwich diaphragm seal (3) between the v shaped ring that sandwiches or several v shaped rings (2) between main body (1) and the gland nut (4) or sandwiching, and change main body into internal thread by outer silk, change gland nut into outer silk by internal thread.Fastening nut compresses v shaped ring, because resiliently deformable takes place, the V-type circle tightens pipeline among embedding tube wall and main body, is in diaphragm seal between two v shaped rings and tightly is squeezed in because volume is compressed among the slit between v shaped ring and the tube wall, realizes sealing function; When joint bears shaking force and moment of flexure, because material does not far reach yield limit, so v shaped ring can discharge the elasticity deposit immediately.Guarantee that joint does not tightly leak; When axial force appears in pipeline.V shaped ring utilizes self-locking effect cleverly, increases the bond stress of joint.
The utility model feature is a v shaped ring.It selects for use spring steel, low alloy steel, alloyed steel, tool steel, Fine Steel Casting iron, stainless steel, engineering plastics etc. to have the material of certain elasticity, hardness and intensity to make according to differences such as the kind of the kind of tubing and the medium carried, temperature, pressure, generally should select the intensity than tubing, the material that hardness is high slightly for use.V shaped ring can be selected for use a slice, two etc. generally to be no more than five and be advisable.Can sandwich diaphragm seal between sheet and the sheet, also can not press from both sides.Diaphragm seal visual media kind, the isoparametric different mining of temperature are made of sheet materials such as rubber, asbestos rubber, engineering plastics.The geometrical shape of v shaped ring generally should be according to the Young's modulus of material itself, angle, width and the thickness of caliber size decision tool cross section angle.Angle is between 120 °-160 ° generally speaking.Width should be between 3-50MM, and thickness is between 0.2-2.5MM.V shaped ring is produced in batches and is advisable with impact briquetting.
Main body and gland nut generally use the malleable cast iron casting comparatively economical.Also can make as other material such as 30#, 45# steel, stainless steel, copper, plastics.Utilize the equipment of producing pipe fitting to meet the demands during batch process.
The utility model has reliable operation than general pipe coupling economical with materials 20%-35% commonly used, and simple in structure, volume is little, advantages such as beautiful shape.It is applicable to various pipelines, the interface of instrument and equipment.Allow the blanking measurement error to reach more than the 30-50MM during installation easy to use of this joint.Use this joint can accelerate piping erection speed, alleviate labor strength, guarantee installation quality, reduce power consumption.
Figure of description is a generalized section of the present utility model.
(1) main body, (2) v shaped ring, (3) diaphragm seal, (4) gland nut, (5) pipeline among the figure.
Below by Figure of description, concrete example in kind of the present utility model is done introduction.
Embodiment
Main body is selected malleable cast iron casting internal diameter 33.5MM, external diameter, 43.6MM, the long 12MM of screw thread part workability, internal diameter 46MM, external diameter 60MM for use among the embodiment.Root without screw thread partial-length 3MM, length overall 80MM; Gland nut external diameter 48.95MM, internal diameter 33MM, screw thread length 12MM, without screw thread partial-length 10MM; 160 ° of width 6MM of " V " shape circle angle, thickness ∮=0.5mm, inner edge diameter 33.6MM, external profile diameter 45.6MM, select the inside and outside edge part surface of 45# steel degree of finish V7 for use, quenching hardness HRC40 selects two " V " shape circles for use, diaphragm seal is selected asbestos packing sheet ∮=1MM for use, also is pressed into " V " shape.Working pressure 1MPa.
Claims (3)
1, a kind of pipe coupling, by known main body, gland nut, sealing is formed, feature of the present utility model is to sandwich one or several v shaped rings between main body and gland nut, or sandwiches diaphragm seal between the v shaped ring that sandwiches, and changes main body into internal thread by outer silk, change gland nut into outer silk by internal thread, fastening nut compresses v shaped ring can tighten pipeline.
2, by the described pipe coupling of claim 1, it is characterized in that the v shaped ring cross section is V-shaped, its tapering and has the radius of turn of corresponding width, thickness and root generally between 120 °-160 °.
3, by the described pipe coupling of claim 1, it is characterized in that v shaped ring can have the material of certain elasticity, hardness and intensity to make with spring steel, tool steel, stainless steel, Fine Steel Casting iron, engineering plastics etc.
