Description

Recharge multi joint {RECHARGE MULTI JOINT}

This design combines only the advantages of ball joint and slide joint, which flexibly connects ground pipes in fluid transportation, to reduce vibration and shock in all directions such as linear movement in the axial direction and angle change in the rotation direction. The present invention relates to a recharge multi joint, which is an external packing injection type that ensures the stability of a pipe. In general, a pipe for transporting a fluid is affected by expansion, contraction, torsion, etc. due to external temperature change and the temperature and pressure of the fluid being transported. Will receive. In addition, the pipes are deformed by shocks or earthquakes. Therefore, the pipe connection is required a joint device that can mitigate the deformation movement of the pipe. Otherwise, a crack may occur in the pipe connection at a certain part of the pipe connection, causing fluid leakage and a safety accident.

In order to prevent such an accident, a joint is installed at the pipe connection part, and a slide joint is widely used to have elasticity in the straight direction of the pipe. However, slide joints are vulnerable to vibrations and shocks that have a small angle with the pipe axis.

Therefore, ball joints that alleviate the impact of pipes are used for shocks and vibrations of various angles. However, these ball joints do not function at the site of the stretch joint in the same linear direction the slide joint is the same. In addition, existing multifunctional joints do not have independent packing inserts in the slide joint in case of fluid leakage, so they need to be replaced with new joints.

Therefore, the present invention is designed to compensate for the shortcomings of the two joints used in the past, and combines only the advantages of the ball joint and the slide joint, and vibrates in all directions such as the linear movement in the axial direction of the pipe and the angle change in the rotational direction. By mitigating shocks, it ensures the stability of the connected pipes and provides recharge multi joint which is an external injection packing method that can be shut off urgently by installing each packing part of ball joint and slide joint independently in case of fluid leakage.

In order to solve the above object, the rechargeable multi-joint, which is an external injection packing method according to the present invention, has a multi-spherical tube having a ball part fixed to rotate in any direction in an angle of rotation in a joint device connecting pipes, It includes a slide portion inserted into the multi-spherical tube to fix the change in the axial direction. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a cross-sectional view of the multi-recharge joint according to the present invention, Figure 2 is a right side view of Figure 1, Figure 3 is an enlarged slide in detail showing the main portion of Figure 1, Figure 4 is the main portion of Figure 1 It is the ball part which extracted the part and expanded in detail.

The present invention is integrally mounted so that the ball portion 201 of the multi-spherical tube 200 can be rotated 360 ° inside the combination by welding the socket 110 and the casing 111. A space for filling the powder packing 1 600 is formed between the outer circumferential surface of the ball portion 201 of the multi-spherical tube 200 and the casing 111, and for this purpose, the ball portion 201 of the multi-spherical tube 200 is formed. ) The front and rear ends of the ball guide 1 (301) and the ball guide 2 (302) is mounted, the ball inside

Grand packing 1 (401) and the ball grand packing 2 (402) is installed. The ball part packing cylinder 112 is attached to the casing 111 to fill the powder packing 1 600 from the outside, and the ball part packing after filling the powder packing 1 600 through the ball packing cylinder 112. The injection bolt 113 is fastened to the ball packing cylinder 112 to close the ball 201.

In addition, the slide portion 202 installed in the multi-spherical tube 200 is a linear reciprocating motion in the axial direction up to the inner diameter of the ball portion 201, and the slide portion 202 prevents buckling during the linear reciprocating motion into the inner diameter of the ball portion 201. In order to reduce friction and wear, slide guides 1 and 701 are provided at the front and rear ends. A space for filling the powder packing 2 601 is formed between the inner side of the multi-spherical tube 200 and the outer circumferential surface of the slide part 202, and the slide part in the annular space so that the powder packing 2 601 does not leak. Grand packing 1 (501) and the slide grand packing 2 (502) was installed.

In addition, a slide packing cylinder 812 is attached to the multi-spherical tube 200 to fill the powder packing 2 601 from the outside, and the powder packing 2 601 is filled through the slide packing cylinder 812. Then, the slide part packing injection bolt 813 is fastened to the slide part packing cylinder 812 to close the slide part 202.

In addition, a stop pin 203 is installed at the end of the slide unit 202 so that the slide unit 202 does not escape during the straight reciprocating motion in the inner diameter of the ball unit 201.

Now with reference to the drawings described will be described for the installation method of the present invention.

The ball part 201 of the multi-spherical tube 200 is moved up and down or left and right to adjust a required angle. At this time, the ball unit 201 adjusts the angle while turning in the ball guide 1 (301) and the ball guide 2 (302) and the ball grand packing 1 (401) ball grand packing 2 (402) installed in the front and rear. After adjusting the angle in this way, the slide portion 202 is moved in a straight line to connect with the fluid transfer pipe at an appropriate position. In order to further maintain the airtightness of the joint, powder packing 1 (600), powder packing 2 (through the ball packing cylinder 112 and the slide packing cylinder 812 attached to the ball part 201 and the slide part 202). 601). This improves airtightness to the ball recharge multi-joint to prevent fluid leakage.
