Abstract
The utility model discloses a taper thread flaring type transition joint which comprises a spherical surface, a flaring type joint body, a hexagon head and taper threads. The taper thread flaring type transition joint is characterized in that the spherical surface is arranged at the end of the flaring type joint body, the hexagon head is arranged on the outer diameter of the middle of the flaring type joint body, the taper threads are arranged on the rear portion of the flaring type joint body, and a through hole is formed in the middle of the flaring type joint body. The radian of the spherical surface and the radian of a contact body connected with the spherical surface are matched. A transition groove is formed between the flaring type joint body and the hexagon head. The spherical surface is machined at the end of the taper thread flaring type transition joint, and forms face seal and linear seal with the connected contact body. Universality is good, sealing performance is high, reliability is high, the structure is simple and installation and use are convenient to achieve.
Description
Technical field
The utility model belongs to dynamic power machine.
Background technique
Existing tapered thread flared type transit joint shortcoming: adopt face sealing means, sealing surface requirement on machining accuracy is high, form and position tolerance is difficult to assurance, and sealing surface is easy to wear, causes leakage.Tapered thread flared type transit joint is a kind of transit joint of responsible switching screw thread, and general flared fitting adopts face sealing means, and sealing surface requirement on machining accuracy is high, and form and position tolerance is difficult to assurance, and sealing surface is easy to wear, causes leakage.
Summary of the invention
The purpose of this utility model is to provide a kind of tapered thread flared type transit joint to process sphere on original flared fitting conical surface basis, and with the jointing forming surface of the other end and the sealing of line, this transit joint sealing is reliable, and beautiful shape is simple in structure.
Technical solution of the present utility model is such, a kind of tapered thread flared type transit joint, comprise sphere, flaring type joint body, hexagon head, tapered thread, it is characterized in that there is sphere (1) flaring type joint body (2) termination, flaring type joint body (2) intermediate outer has hexagon head (3), flaring type joint body (2) has tapered thread (4) below, in the middle of flaring type joint body (2), is through hole.
The formation that matches of the radian of sphere (1) and the radian of the contact being connected.
Sphere (1) and the jointing handing-over forming surface of the other end and the sealing of line.
Flaring type joint body (2) is to there being transition hole groove between hexagon head (3).
The utility model has the advantages that: tapered thread flared type transit joint, on flared fitting conical surface basis, process sphere, with the jointing forming surface of the other end and the sealing of line.This transit joint is simple in structure, easy to manufacture, easy to install, highly versatile, and good airproof performance, reliability is high.
Accompanying drawing explanation
Fig. 1 is that the overall structure master of a kind of tapered thread flared type of the utility model transit joint looks sectional view.
reference character: sphere (1), flaring type joint body (2), hexagon head (3), tapered thread (4).
Embodiment
Most preferred embodiment of the present utility model is such, comprises sphere, flaring type joint body, hexagon head, tapered thread.On the flaring type joint body of transit joint, the conical surface is processed with sphere, and sphere contacts with the corresponding conical surface, realizes linear sealing.With reference to Fig. 1, flaring type joint body (2) intermediate throughholes, there is sphere (1) flaring type joint body (2) termination, and the radian of sphere (1) and the tapering of connecting body manufacture and form line face and contact and reach sealing.Flaring type joint body (2) rear end external diameter has tapered thread (4).Flaring type joint body (2) intermediate outer is hexagon head (3).Between flaring type joint body (2) and hexagon head (3), there is transition hole groove.
Claims (4)
1. a tapered thread flared type transit joint, comprise sphere, flaring type joint body, hexagon head, tapered thread, it is characterized in that there is sphere (1) flaring type joint body (2) termination, flaring type joint body (2) intermediate outer has hexagon head (3), flaring type joint body (2) has tapered thread (4) below, in the middle of flaring type joint body (2), is through hole.
2. according to a kind of tapered thread flared type transit joint claimed in claim 1, the formation that matches of the radian that it is characterized in that sphere (1) and the radian of the contact being connected.
