Description

A convenient disassembly and reusable small-diameter pipe pressing device

technical field

The utility model belongs to the technical field of heat pipes and relates to small-diameter heat pipes, in particular to a small-diameter pipe pressing device which is convenient to disassemble and can be reused.

Background technique

The heat pipe is a heat transfer element with high thermal conductivity developed in recent decades. The heat pipe was first used in the aerospace field. Today, it has expanded from the uniform temperature and temperature control in aerospace and spacecraft to various fields of industrial technology. , Petroleum, chemical industry, energy, power, metallurgy, electronics, machinery and medical and other departments have gradually applied heat pipe technology.

Since there is a medium circulating in the heat pipe, a pressure test must be carried out before use. The traditional pressing equipment has complex structure, cumbersome operation and low labor efficiency.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a small-diameter pipe pressing device which is convenient to disassemble and can be reused. The device has a simple structure, is convenient to operate, and improves working efficiency.

The scheme of the present utility model is realized like this:

A small-diameter pipe pressure device that is easy to disassemble and reusable, including rubber plugs, plugging wires and pressure testing wires. Rubber plugs are installed coaxially on the inner walls of both ends of the pipe body to be tested, and are located in the rubber plug at the left end. The coaxial thread is fitted with a plugging screw, and the coaxial thread in the rubber plug at the right end is fitted with a pressing screw. The screw heads of the blocking screw and the pressing screw are both tapered and located in Inside, the ends of the screw rods of the plugging screw and the pressing screw are respectively located outside the pipe body and locked by the blocking nut and the pressing nut.

Moreover, a through hole is coaxially formed in the middle part of the pressing jack wire.

Moreover, gaskets are installed on the inner ends of the blocking nut and the pressing nut respectively.

Advantage and positive effect of the present utility model are:

The device realizes the sealing with the pipe body by extruding the conical screw head of the top screw and stretching the rubber plug. The device has the advantages of simple structure, convenient and quick operation, effective efficiency improvement, and reusability, which has the value of wide popularization and application.

Detailed ways

Below in conjunction with accompanying drawing and through specific embodiment the utility model is described in further detail.

A convenient disassembly and reusable small-diameter pipe pressing device, as shown in Figure 1, includes a rubber plug 6, a plugging screw 3 and a pressure testing screw 5, and the inner walls of the two ends of the tube body 4 to be tested are respectively coaxial Install the rubber plug, the coaxial thread in the rubber plug at the left end is threaded with a plugging screw, and the coaxial thread in the rubber plug at the right end is threaded with a pressing screw, the screw head of the plugging screw and the pressing screw Both are tapered structures and are located inside the pipe body respectively. The screw ends of the plugging jackscrew and the pressing jacking screw are respectively located outside the pipe body and locked by the plugging nut 1 and the pressing nut 8 .

In this embodiment, the mechanism for pressing the jacking wire is shown in Figure 2, in Figure 2 (a) is the front view of pressing the jacking wire, (b) is the left side view, and the pressing jacking wire is coaxially formed with a through hole 5A .

The structure of the plugging jack wire is shown in FIG. 3 .

A gasket 2 and a gasket 7 are installed on the inner ends of the plugging nut and the compression nut respectively.

The using method of the utility model is:

1. Extend the rubber plug, plugging wire and pressure testing wire into the pipe body to be pressed from both ends (the threaded side is outside), and pay attention to ensure the size of the extension;

2. Place gaskets and nuts to firmly fix the device at both ends of the pipe body;

3. Tighten the nuts at both ends, and squeeze and expand the rubber plug to ensure the tightness of the connection between the pressing device and the inner wall of the tube;

4. Connect the device to the connecting pipe 9 of the pressing machine through the nut 8, and start water injection and pressing;

5. After the hydrostatic test is over, loosen the nuts at both ends of the pipe respectively to remove the entire pressing device and continue pressing the next pipe or store the pressing device.

It should be emphasized that the embodiments described in the utility model are illustrative rather than restrictive, so the utility model includes but not limited to the embodiments described in the specific implementation, and those skilled in the art according to the utility model Other implementations derived from the new technical solution also belong to the scope of protection of the utility model.
