Description

The utility model is related to joints, more specifically, a joint element suitable for various pipelines, which makes the connection simple, easy and stable, and prolongs the life of pipelines.

The currently commonly used pipe joint components are shown in Figure 1. They are pipe bodies that are turned at right angles. One end (2) has a larger pipe diameter and outer diameter. The tee or two-way pipe fitting (not shown in the figure) connected to the input part, the other end (4) has a smaller diameter and outer diameter, a section of external thread (5) is provided at the rear end, and a reduction tube is provided at the front pipe end The caulking part (6) of the diameter, and a raised strip (7) is set around the appropriate place, which is for the pipe body (8) of the output part corresponding to the pipe diameter to be inserted forcibly, and the pipe body (8) It is forced to expand here to make the connection between the two tighter, but it must be tied with tightening elements (9) such as C-shaped buckles and iron wires. In some cases, leak-proof gaskets must be put on to prevent It is not practical to prevent water leakage or air leakage, as shown in Figure 2, but due to the drop in the inner diameter of the joint (1), the flow rate changes rapidly from large to small, so that the pressure of the fluid passing through changes greatly, and the pipe body of the output piece ( 8) Only the additional tightening element (9) is used to tighten it. Over time, the pipe body (8) is prone to loosening or even bursting and damage, resulting in fluid leakage. Therefore, frequent safety inspections and maintenance are required, which is very inconvenient.

The main purpose of this utility model is to provide a new type of pipe joint element suitable for various pipelines, which makes the connection simple, easy and stable, and prolongs the life of the pipeline.

The utility model provides a new type of pipe joint element suitable for various pipelines. It is composed of a pipe body in the shape of a right angle, with appropriate inner and outer pipe diameters. Both pipe ends are provided with a section of outer pipe. One end is a pipe connector for screwing the input piece, and the other end is matched with a joint to tightly connect the pipeline of the output piece. The appearance of the joint sleeve is hexagonal like a nut for easy gripping. An inner screw hole is set in the center to match the outer thread of the pipe body, and a conical pipe is provided on the center of the circle. The tapered pipe has an appropriate length and does not exceed the joint sleeve itself, and the bottom of the body is thicker It gradually decreases upwards, but its central hole is the same diameter, which corresponds to the inner diameter of the pipe body, so that the pipeline of the output part can extend into the central hole of the tapered pipe. When the joint sleeve and the pipe body screw When appropriate, it is characterized by direct compression of the pipeline due to the function of the tapered tube.

A preferred embodiment is hereby given and explained in conjunction with the drawings:

Fig. 3 is a three-dimensional exploded view of a preferred embodiment of the present invention.

Fig. 4 is a schematic cross-sectional view of a preferred embodiment of the present invention.

Please refer to Fig. 3, the utility model is a novel pipe joint element (10) suitable for various pipelines. diameter, the inner diameter of the pipe is the same, and it is different from the conventional one, which can avoid the pressure drop in the pipe body (11). It is a pipe connector for screwing the input piece, generally such as a two-way or three-way pipe (not shown), and the other end is matched with a joint sleeve (12) to tightly connect the pipeline (13) of the output piece (see Shown in Fig. 4); this joint sleeve (12) is hexagonal as nut-like, is beneficial to grip operation, and a larger inner screw hole (121) is established in the center, corresponding to one end of the pipe body (11) ( 112) the external thread must be screwed together, and a tapered pipe (122) is established with the protrusion of the center of the circle, and this tapered pipe (122) has an appropriate length dimension, and does not exceed the joint sleeve (12) itself. The tapered tube (122) has a central hole (123) that runs through the same diameter, and a stop portion (124) with a smaller diameter is provided at the front end, and the bottom of the tapered tube (122) is thicker and gradually shrinks upwards, resulting in the tapered tube (122). ) and the internal screw hole (121) is characterized by a gradually smaller gap from outside to inside. When the pipeline (13) is inserted into the joint sleeve (12), the front end of the pipeline (13) is matched with an insertion part with a reduced outer diameter, and the two are offset and closely contacted during insertion to strengthen the connection effect.

According to the combination of the above-mentioned structural devices, please refer to Figure 4, when the gas port used for the gas or fluid piping of the fluid machine is used, one end (111) of the pipe body (11) of the present utility model is directly screwed to the pipe connection of the input piece. When the other end (112) is a pipeline connected to the output piece, the front end of the pipeline (13) is provided with an insertion part (131) with a reduced outer diameter, and the pipeline (13) is directly inserted into the joint from the bottom of the joint sleeve (12) The tapered pipe (122) of the sleeve (12) is in the central hole (123), and the tapered pipe (122) is extended so that the insertion part (131) of the pipeline (13) and the tapered pipe (122) stop The parts (124) are in close contact, and then the joint sleeve (12) is directly screwed with the end (112) of the pipe body (11). The gap between the holes (121) gradually becomes smaller, but the thickness of the tube body (11) itself remains unchanged, so the more screwed in, the tube body (11) is forced to compress the conical tube (122) with the force of compression deformation, and It has the effect of compressing and tightening the pipeline (13) that extends into the tapered pipe (122) and is in close contact with it, so after the screwing is completed, the pipe body (11) and the pipeline (13) are connected at the same time; The novel pipe joint element (10) suitable for various pipelines cooperates with the special pipe body (11) and the joint sleeve (12), and provides the following advantages.

(a) The inner diameter of the pipe body (11) remains unchanged, and there is no pressure difference when the fluid circulates inside, and the circulation is smooth. It can be made into various sizes and specifications to meet the needs of different sizes and is suitable for various pipelines;

(b) Directly use the design of the joint sleeve (12) with the inner screw hole (121), the tapered pipe (122) and its center hole (123) to stop the part (124), so that the pipeline (13) and the joint sleeve (12) The tight connection is compressed and deformed to tighten the connection, without additional tightening elements, leak-proof gaskets, etc., and the connection and assembly are simple and easy;

(c) The pipeline joint element (10) of the utility model connecting the output piece and the input piece, the two pipe ends have the same pipe diameter, and the pipe diameter of the joint sleeve (12) and the pipe body (11) connecting the smaller pipeline of the input piece The drop is also small, the input and output pressures are equal and the pipeline (13) is inserted into the joint element (10), which will not break and break as usual, and the situation of fluid leakage will not occur, and it can prevent water leakage during the operation of the machine phenomenon of air leakage;

(d) It only needs to be composed of a pipe body and a joint sleeve, the parts are simple, the cost is low, and the life of the pipeline is prolonged.

To sum up, the utility model, with its special space form and innovative structure, provides easy and stable assembly and connection actions, and the pipeline will not burst and damage to prolong its life. It has advanced efficacy, practicability and novelty, and meets Regulations on utility model patents.
