Abstract
The utility model relates to the technical field of joints, in particular to a flaring joint sealing structure, which is arranged on a steel pipe and is characterized by comprising a joint body, a flaring nut, an O-shaped ring and a flaring bushing, wherein the outer surface of one end of the joint body is conical and is butted against the inner surface at a flaring of the steel pipe; the inner surface at one end of the flaring bushing is conical and is butted against the outer surface at the flaring of the steel pipe; the outer surface of the joint body is provided with external thread; the inner wall of the flaring nut is provided with internal thread and is sleeved on the steel pipe; the external thread is matched with the internal thread; the conical surface of the joint body is provided with a notch; and the O-shaped ring is arranged in the notch. The utility model provides the flaring joint sealing structure which has the advantages of simple and compact structure, convenience in mounting and use and good sealing property.
Description
Technical field
The utility model relates to the joint technical field, specifically a kind of flare type joint sealing configuration.
Background technique
Existing in the market integrated type flare type joint all is to adopt the joint conical surface and pipe enlarging face to be squeezed into sealing surface to realize pipe sealing; This cutting to pipe, enlarging require than higher, and the cutting of pipe and enlarging are improper or do not reach the risk that requirement then can bring leakage.
The model utility content
The utility model is for providing flare type joint sealing configuration a kind of simple and compact for structure, easy to install, good airproof performance.
The utility model is realized through following technical proposals:
A kind of flare type joint sealing configuration is installed on the steel pipe, comprises fittings body, enlarging nut, O type circle and enlarging lining; Said fittings body one end outer surface is tapered, and touches with the contacted inner surfaces of enlarging place of said steel pipe, and said enlarging lining one end internal surface is tapered; And inconsistent with the outer surface of enlarging place of said steel pipe, said fittings body outer surface is provided with outside thread, and said enlarging nut inner wall is provided with internal thread; And be sheathed on the said steel pipe; Said outside thread matches with internal thread, and the conical surface of said fittings body is provided with groove, and said O type circle is located in the groove.
Said enlarging sleeve outer surface is provided with first step, and said enlarging nut internal surface is provided with second step, and said second step and first step are inconsistent.
Said enlarging lining is a nut.
The beneficial effect that the utility model brought is:
In the utility model, said flare type joint sealing configuration comprises fittings body, enlarging nut, O type circle and enlarging lining, and groove is set on fittings body; O type circle is put into said groove to be installed again; Then between said fittings body, increase sealing at steel pipe, improved sealability, anti-leakage ability is better; And O type circle adopts softer material to process, and just installed by the force compresses rear; Said second step and first step are inconsistent, in said enlarging nut and the stubborn each other process of closing of fittings body, can make the enlarging lining further compress enlarging place of said steel pipe, seal more reliable; Bell mouth angle after enlarging place of said steel pipe is consistent with fittings body conical surface angle; The bell mouth angle of said enlarging lining horn mouth and steel pipe enlarging place has certain differential seat angle; The said enlarging nut of turn promotes the enlarging lining and moves; And then thereby extruding steel pipe and enlarging conical surface form firmly and seal, and said O type circle has produced sealing when not forming hard sealing surface, so just avoid turn enlarging nut to cause leakage inadequately because of moment; In addition, said O type circle can push some the indenture defectives that can fill up said steel pipe enlarging place surface, avoids leaking.
