In general, the gas pressure regulator is a key device installed in the gas piping line. The gas pressure regulator performs a function of reducing the pressure from the high pressure to the medium pressure and the low pressure to the low pressure by appropriately adjusting the pressure of the gas supplied from the supplier to the user. will be.

As described above, the pressure regulator separates the pressure regulator from the pipe for parts replacement or maintenance, and then the internal configuration of the pressure regulator is separated one by one, and the assembly operation is performed again.

As a device for use in such a normal operation, there has been proposed a device for assembling a pressure regulator of Korean Patent Utility Model No. 20-0453562. This assembling apparatus enables a simple and accurate assembly because the sleeve is assembled at a uniform pressure by the pressure of the pressure plate.

However, the assembly apparatus as described above has a problem that the portability and workability of the assembly device is not only complicated but also the volume is very large for the operator to use.

Meanwhile, as shown in FIG. 1, a tube core 20 is provided inside the body 10, and a rubber material is formed between the body and the tube core. The static pressure regulator in which the tube 30 is provided is called a tubular constant pressure regulator.

When the tube type pressure regulator as described above replaces or maintains parts, it is very cumbersome for the worker to grasp a relatively heavy tube core and separate it from the body. Most of the work is performed using general machine tools. do. In addition, there is a high possibility of scratching the tube core due to excessive work, and above all, there has always been a risk of safety accidents due to unstable work.

However, the device for assembling the pressure regulator is different from the tubular pressure regulator of the present invention and cannot be adopted for separating and assembling the tube core in the tubular pressure regulator. The tube core can be easily separated and assembled from the tubular pressure regulator. The development of the jig used for the purpose is very urgent.

The present invention has been made to solve the above problems, and an object thereof is to provide a jig that is used to easily separate and reassemble the tube core from the tubular constant pressure.

In order to achieve the above object, the present invention is to separate the tube core from the tubular pressure regulator consisting of a tube core provided on the inside, a regulator body provided on the outside, and a tube provided between the tube core and the regulator body and As a jig used to reassemble it, a support having a rectangular through-hole is formed, the support is formed opposite the fastening hole at both ends; A screw threaded to the fastening hole, the handle having a predetermined length of thread; And a latch that is coupled to one end of the handle and is moved within the through hole by the rotation of the handle and is caught by the tube core groove formed on the inner surface of the tube core.

Here, according to the present invention, the clasp, the head portion is protruding from both sides so that the upper portion is caught by the support, the leg portion is formed extending from the head and the end is bent, protruding from the end surface of the leg portion It is characterized by consisting of a locking portion.

In addition, the handle is fastened through the leg portion of the latch and characterized in that the separation is prevented by the snap ring.

According to the present invention, it is not only possible to easily separate from the pressure regulator without damaging the tube core by a simple operation by interlocking with the handle so that the gap is adjusted by rotation of the brace that is caught in the tube core groove formed on the inner surface of the tube core. In addition, when it is reassembled, it is possible to apply it, so that the working time can be drastically shortened, and the stability according to the work is expected to be effective.
