Description
Technical field
The utility model relates to a kind of jointing of pipeline, particularly a kind of easy replace tubes joint.
Background technique
At present, (be not limited to water piping at water piping, also can be the pipelines such as steam pipe, oil pipe) in, Fig. 7 shows the linkage structure of a kind of valve (particularly total valve), valve 4 is connected to by the left and right sides flange on it (41,42) between the flange (511,521) of left and right sides water pipe (51,52), is lined with respectively seal washer (61,62) between the flange (511,521) of the left and right sides of valve 4 flange (41,42) and left and right sides water pipe (51,52).When valve 4 has been gone bad will change the time, generally be first with new seal washer (61,62) be placed with respectively at left and right sides water pipe (51,52) flange (511,521) locate, then valve 4 is pressed into two seal washers (61,62) between, because original valve 4 when mounted, with seal washer (61 by bolt, 62) be pressed on respectively the left and right sides flange (41 of valve 4,42) with left and right sides water pipe (51,52) flange (511,521) between, original seal washer (61,62) be subject to compression, so new seal washer (61 of changing, 62) thickness adds that the radial length of valve 4 often is greater than left and right sides water pipe (51,52) flange (511,521) distance between, so just be difficult to new seal washer (61,62) and new valve 4 snap in left and right sides water pipe (51,52) flange (511,521) between, in the practice, be used for left and right sides water pipe (51 by manpower often, 52) flange (511,521) pry open certain distance to both sides, just may be with new seal washer (61,62) and new valve 4 snap in left and right sides water pipe (51,52) flange (511,521) between, if the total valve of a running water pipe has been broken, its water pipe diameter is huge, even with left and right sides water pipe (51,52) it also is very difficult prizing one millimeter toward both sides, so snap in new seal washer (61,62) and new valve 4 are the time-consuming things of requiring great effort very much, and be easy to snapping in new seal washer (61,62) and during new valve 4 with new seal washer (61,62) card is bad.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of easy replace tubes joint is provided, it can be connected to valve or other tubular union on the pipeline (comprising the pipelines such as water piping, oil pipe circuit, steam pipe circuit), and can be so that change valve or other tubular union more convenient and quicker, time saving and energy saving, can not damage seal washer yet.
The technical solution of the utility model is: a kind of easy replace tubes joint, and it comprises adapter, clamp sleeve and packing washer, takes over to be tubulose, the one end is provided with screw thread; Clamp sleeve is tubulose, one end inboard be provided with take over an end on the screw thread that matches of screw thread; Packing washer is installed in the clamp sleeve and is positioned at the end of adapter, and clamp sleeve is provided with a ring-shaped step or annular slope corresponding to the position of packing washer, and the inboard of the end of adapter is provided with an annular slope corresponding to the position of packing washer.
The further technological scheme of the utility model is: also be provided with the extruding circle in the described clamp sleeve, the extruding circle is between the ring-shaped step and packing washer of clamp sleeve, and it is made by metallic material.
The utility model further technological scheme is: the other end of described adapter is provided with for the flange, outside thread or the internal thread that connect.
The utility model further technological scheme is: described packing washer is that rubber is made.
The utility model compared with prior art has following features:
The utility model can be connected to valve or other tubular union on the pipeline (comprising the pipelines such as water piping, oil pipe circuit, steam pipe circuit), and can make replacing valve or other tubular union more convenient and quicker, time saving and energy saving, can not damage seal washer yet.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
