Abstract
An inner screw thread reducing joint comprises a cylinder shape plastic pipe, an annular connection portion is arranged in the end opening on one end of the plastic pipe with the inner diameter of the annular connection portion smaller than that of the plastic pipe, and an inner whorl is arranged on the other end of the plastic pipe. The inner whorl is cone shape. The plastic pipe can be connected with an elbow or a three-way-type pipe through inserting the plastic pipe into a flat pipe socket of matched elbow or three-way-type pipe and gluing or melting any one flat pipe socket of the two flat pipe sockets of the elbow or three flat pipe sockets of the three-way-type pipe, thereby flat pipe socket of the elbow or the three-way-type pipe is capable of connecting whorl. The utility model increases the degree of freedom of pipe arrangement and can install conveniently the pipe member of the faucet, valve and joint.
Description
Technical field:
The utility model relates to pipeline machinery, relates in particular to assembling pipe joint, particularly a kind of internal thread reducer union.
Background technique:
In the prior art, the plastic water supply pipe pipe fitting, joint as elbow, threeway etc. adopts flat bellmouth mostly, interior rib-loop is not set, and at the scene during installation, run into sometimes and need and be the situation of pipe fittings such as tap that small dimension is installed on the pipe fitting of flat bellmouth, valve, joint at the bore of common big specification, for existing plastic water supply pipe pipe fitting, can only select the method that changes pipe fitting for use, make troubles and lose to installation.
Summary of the invention:
The purpose of this utility model is to provide a kind of internal thread reducer union, and the flat bellmouth joint that described this internal thread reducer union will solve plastic water supply pipe pipe fitting of the prior art can not change bore, the bellmouth that flattens is the technical problem of threaded coupling simultaneously.
This internal thread reducer union of the present utility model is made of a columned plastic tube body, wherein, the port of one end of described plastic tube body is provided with a ring-type end-to-end joint part, the internal diameter of described ring-type end-to-end joint part is less than the internal diameter of described plastic tube body, and the other end of described plastic tube body is provided with internal thread.
Further, the diameter of the external diameter of described plastic tube body is 25mm.
Perhaps, the diameter of the external diameter of described plastic tube body is 32mm.
Perhaps, the diameter of the external diameter of described plastic tube body is 40mm.
Further, described internal thread is that internal diameter is 1/2 inch a circular cone internal thread.
Perhaps, described internal thread is that internal diameter is 3/4 inch a circular cone internal thread.
Perhaps, described internal thread is that internal diameter is 1 inch a circular cone internal thread.
Further, the outside of the outer end of described ring-type end-to-end joint part is coniform.
Working principle of the present utility model is: plastic tube body is inserted the flat bellmouth in the pipe fittings such as the elbow be complementary or threeway, as any one bellmouth in two flat bellmouths of elbow, perhaps any one bellmouth of three flat bellmouths of threeway, by bonding or welding mode, plastic tube body is connected with pipe fittings such as elbow or threeways, can obtains the ability of being threaded in the flat bellmouth in the pipe fittings such as elbow or threeway.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model has increased the degrees of freedom that pipeline is provided with for the flat bellmouth in the pipe fittings such as elbow or threeway provides the ability of being threaded.The conduit component of tap, valve, joint can be installed easily.
Description of drawings:
Fig. 1 is the generalized section of internal thread reducer union of the present utility model.
Fig. 2 is that internal thread reducer union of the present utility model is installed in the schematic representation on the tee pipe fitting.
Fig. 3 is the use schematic representation that internal thread reducer union of the present utility model connects tap.
Embodiment:
As shown in Figure 1, internal thread reducer union of the present utility model is made of a columned plastic tube body 1, wherein, the port of one end of described plastic tube body 1 is provided with a ring-type end-to-end joint part 2, the internal diameter of described ring-type end-to-end joint part 2 is less than the internal diameter of described plastic tube body 1, and the other end of described plastic tube body 1 is provided with internal thread 3.
Further, the diameter of the external diameter of described plastic tube body 1 is 25mm.
Perhaps, the diameter of the external diameter of described plastic tube body 1 is 32mm.
Perhaps, the diameter of the external diameter of described plastic tube body 1 is 40mm.
Further, described internal thread 3 is that internal diameter is 1/2 inch a circular cone internal thread.
Perhaps, described internal thread 3 is that internal diameter is 3/4 inch a circular cone internal thread.
Perhaps, described internal thread 3 is that internal diameter is 1 inch a circular cone internal thread.
Further, the outside of the outer end of described ring-type end-to-end joint part 2 is coniform.
As shown in Figure 2, the utility model inserts in three common flat bellmouths of a threeway 4, thereby has realized the reducing effect of any end of threeway 4, and become common flat bellmouth and be threaded socket, thus the satisfied needs that parts such as tap, valve or joint are installed.
As shown in Figure 3, the utility model inserts in the common flat bellmouth of threeway 4, becomes common flat bellmouth and is threaded socket, connects a tap 5 by internal thread 3 then.
