Description

Marking device for pipe connection

The present invention relates to a pipe joint marking device used to connect a pipe used for supply of water supply, etc. with a connection socket, and more specifically, it can be identified with the naked eye by marking the optimal insertion limit point for connecting the pipe. By making it possible, it relates to a marking device for a pipe joint that can quickly check whether the pipe is inserted into the connection socket at the correct depth so that the stable coupling can be made.

In general, a pipe refers to a pipe body used to transport water, air, gas, etc. by completely blocking the inside and the outside, and such a pipe prevents the outflow of liquid or gas transporting the inside. It has the effect of preventing external contamination.

In particular, pipes used for supplying water supply provide clean water, prevent damage and breakage due to external impact or aging, and are made of lightweight materials to facilitate transportation and construction. It is manufactured and used according to the standard length unit.

Accordingly, when it is necessary to construct a section longer than the length for which the pipe is manufactured, to construct a bent section, or to supply in two or more branches, the work of connecting the pipes must be accompanied.

In general, when connecting pipes, if the end of the pipe is pushed into the connection socket, the grip ring inside the connection socket presses the outer circumferential surface of the pipe, and this grip ring prevents the pipe in the state of being inserted into the connection socket. A connection method that presses the outer surface of the pipe more strongly as the force to fall out is applied is widely used.

This is because it is only necessary to push the end of the pipe all the way into the connection socket, so that the convenience and efficiency of pipe connection work can be improved, and the connection between the pipe and the connection socket can be maintained firmly.

At this time, it is very important to push the end of the pipe all the way into the connection socket for a strong and stable connection between the pipe and the connection socket. If the pipe is connected without being fully inserted into the connection socket, there is a problem that additional repair work must be performed due to a problem such as leakage of water.

However, since the work of connecting the pipe to the connection socket is done manually by the operator, it has no choice but to depend heavily on the skill of the operator, which not only causes the pipe connection work to not be uniform in accuracy, but also has some inaccurate connections. There was a problem in that additional costs such as labor and construction costs were inevitably increased due to the part.

Hereinafter, a marking device for a pipe joint according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The marking device for a pipe joint according to an embodiment of the present invention is for displaying the exact insertion position of the pipe 1 connected through the connection socket 2 with the naked eye as shown in FIGS. 1 and 2 . , is largely configured to include a marking body (10), an insertion display unit (20), a lubricant application unit (30).

Here, the pipe 1 connected through the connection socket 2 is preferably made of PB (polybutylene) material, which is lighter than PE (polyethylene) or PVC (polyvinyl chloride). With good ductility and strong impact resistance, as well as excellent chemical and corrosion resistance, and no risk of damage due to low temperatures even in winter, the need for additional repair work is significantly reduced when connected stably and firmly. because it can be done

However, the pipe 1 to be described below is not limited to the above-described PB, and a pipe made of a material that can be machined in the field and connected to the connection socket 2 in a fitting manner may be applied.

The marking body 10 has a pipe insertion hole 15 into which the pipe 10 can be inserted in the central portion of one side having a size corresponding to the outer diameter of the pipe 1, and the pipe insertion hole 15 at this time is It is formed equal to or deeper than the maximum insertion depth for accurately connecting the pipe 1 to the connection socket 2 .

At this time, the marking body 10 forms a plurality of concavo-convex surfaces on the outer surface or knurling, so that when the pipe 1 is inserted into the pipe insertion hole 15, the hand holding the marking body 10 slides can be prevented.

In addition, the marking body 10 is formed of the same material as the pipe 1 or may be formed of a material different from that of the pipe 1, and the insertion display unit 20 and the lubricant application unit 30 to be described later perform a predetermined number of times. If the filled solution is exhausted after use and it is disposed of and replaced with a new product, it is desirable to improve portability and reduce manufacturing cost by making it with a material that is light in weight and inexpensive.

The insertion display unit 20 is installed in a band shape on the inner circumferential surface of the pipe insertion hole 15, and is filled with a pigment of a preset color so that it can be used repeatedly for a set number of times in a liquid form, and the pipe insertion hole 15 When the pipe (1) is inserted to the maximum depth and pulled out, the insertion appropriate line 21 that can be visually identified is displayed on the outer peripheral surface of the end of the pipe (1).

The insertion titration line 21 at this time allows the operator to visually check whether the end of the pipe 1 is inserted to the correct depth inside the connection socket 2 when connecting the pipe 1 to the connection socket 2 will be.

Accordingly, the insertion indicator 20 for displaying the insertion appropriate line 21 on the outer peripheral surface of the end of the pipe 1 should be formed at a position corresponding to the maximum insertion depth of the pipe 1 connected to the connection socket 2 . will be.

In addition, the insertion display unit 20 is formed to protrude at a certain height toward the center within the pipe insertion hole 15, so that the insertion appropriate line 21 can be clearly displayed on the outer circumferential surface of the pipe 1 inserted into the pipe insertion hole 15. can make it

The lubricant application unit 30 is installed at a position deeper than the insertion display unit 20 on the inner circumferential surface of the pipe insertion hole 15, and is filled with a certain amount of lubricant so that it can be used repeatedly for a set number of times.

Through this, when the end of the pipe 1 inserted into the pipe insertion hole 15 is positioned in the lubricant application unit 30, the lubricant application unit 30 is in contact with the outer circumferential surface of the pipe 1, and the pipe ( Lubricant is applied to the outer peripheral surface of the end of 1).

Here, as shown in the accompanying drawings, the lubricant application unit 30 is preferably formed to occupy a larger area than the insertion display unit 20, which is a rubber in which the pipe 1 is provided inside the connection socket 2 This is to enable smooth insertion by the lubricant while the ring 2c, the washer 2b, and the grip ring 2a are sequentially inserted to the maximum depth.

Looking at the effect of the marking device for a pipe joint composed of the above configuration as follows.

First, insert the end of the pipe (1) to the maximum depth into the pipe insertion hole (15) corresponding to the standard of the pipe (1) to be connected using the connection socket (2).

At this time, the pipe (1) inserted into the pipe insertion hole (15) passes through the insertion indicator (20) position and the insertion titration line (21) is displayed on the outer circumferential surface, and the insertion titration line (21) passes through the position of the lubricant application part (30). A lubricant is applied to the marked outer peripheral surface.

After that, when the pipe 1 is withdrawn from the pipe insertion hole 15, the insertion appropriate line 21 is displayed on the outer peripheral surface of the pipe 1 at a position where it can be accurately connected to the connection socket 2 as shown in FIG. 3a. At the same time, a lubricant is applied between the insertion titration line 21 and the end of the pipe 1 .

Here, since the lubricant application unit 30 is located deeper in the pipe insertion hole 15 than the insertion display unit 20, the lubricant is not applied to the insertion titration line 21 located at the furthest distance from the end of the pipe 1, , the position of the indicated partial insertion titration line 21 so that it can be accurately connected to the connection socket 2 can be clearly identified with the naked eye.

After inserting and withdrawing the pipe (1) to the maximum depth into the pipe insertion hole (15) formed in the marking body (10) in this way, the pipe (1) inside the connection socket (2) for connecting the pipe (1) Insert the end of

When inserting the end of the pipe (1) into the connection socket (2), while looking at the position of the insertion titration line (21) displayed through the insertion indicator (20), the insertion titration line (21) is located inside the connection socket (2). Just push it deep until it's not exposed to the outside.

And since the lubricant is applied to the outer circumferential surface of the end of the pipe 1 by the lubricant application unit 30, when the pipe 1 is inserted into the connection socket 2, it can be smoothly inserted without pushing it with a strong force. there will be

When the pipe (1) is inserted into the connection socket (2) like this, when the insertion titration line (21) marked on the outer peripheral surface of the pipe (1) is not exposed to the outside, the pipe (1) is the maximum inside the connection socket (2). It is inserted into the depth state.

As shown in Figure 3b, the pipe 1 inserted into the connection socket 2 is a grip provided to press the outer peripheral surface of the pipe 1 in the opposite direction from which the pipe 1 is drawn out into the connection socket 2 The connection can be maintained in the state inserted to the maximum depth by the ring 2a, and the grip ring 2a at this time is supported by the washer 2b and the rubber ring 2c, etc. to press the outer circumferential surface of the pipe 1 You can make sure it stays solid.

In this way, the marking body 10 is formed with the same inner diameter as the outer diameter of the pipe 1, and at the same time, the pipe ( When the end of 1) is inserted and pulled out to the maximum depth, the insertion titration line 21 is displayed at a position where it can be accurately connected to the connection socket 2, and the part where the pipe 1 is inserted into the connection socket 2 is The lubricant is applied, and through this lubricant and the insertion titration line 21, the pipe 1 can be smoothly inserted into the connection socket 2 and easily inserted into a position where it can be accurately connected.

As a result, the convenience and efficiency of the operation are greatly improved, and regardless of the skill level of the operator, the insertion depth of the pipe (1) connected to the connection socket (2) can be easily determined with the naked eye and always connected accurately, so water leakage (leakage) ), which has the effect of significantly reducing the maintenance work required.

Here, when inserting the pipe (1) into the connection socket (2), a grip ring (2a) provided to prevent the pipe (1) from being drawn out inside the connection socket (2) presses the outer circumferential surface of the pipe (1). Although it interferes with smooth insertion because It is possible to insert the pipe 1 to the maximum depth with less force.

On the other hand, as shown in FIGS. 4A and 4B, a plurality of marking bodies 10 are provided to form one body, and the pipe insertion hole 15 formed in each marking body 10 is formed according to the standard of the pipe (1). Some or all of them may be formed in the same size or all may be formed in different sizes.

At this time, it is preferable to form the inner diameter and insertion depth of the pipe insertion hole 15 in each marking body 10 provided in plurality in consideration of the standard of the pipe 1 mainly used at the construction site.

Through this, even if the size of the pipe 1 at the construction site is different, one pipe joint marking device is used to insert and withdraw the end of the pipe 1 to the maximum depth into the pipe insertion hole 15 that meets the standard. As long as the insertion titration line 21 is displayed and lubricant is applied at the same time, it is possible to quickly, smoothly and accurately connect the pipe 1 to the connection socket 2 conforming to the standard of the pipe 1 .

Although the accompanying drawings show that the two marking bodies 10 are provided in different directions, in contrast to this, three or more marking bodies 10 are provided to insert the pipe 1 in different directions, or some or All of them may be provided so that the pipe 1 can be inserted in the same direction.

In addition, as shown in Figures 5a and 5b, the marking body 10 is provided with a plurality of may be formed to be detachably coupled to the connection body 40 by the coupling means (45).

As the coupling means 45, a known coupling method for coupling two different objects into one, such as screw coupling, fitting coupling, key coupling, and clamp coupling, and then separating them back to their original state may be applied.

Even at this time, some or all of the pipe insertion holes 15 of each marking body 10 coupled to the connection body 40 are formed in the same size or all according to the standard of the pipe 1 connected to the connection socket 2 . They may be formed in different sizes.

In this way, when a plurality of marking bodies 10 are formed to be separably coupled to the connection body 40, a marking body having a pipe insertion hole 15 having a size that meets the standard of the pipe 1 used at the construction site is formed ( 10) can be optionally connected.

Accordingly, it is possible to change and use the marking body 10 having the pipe insertion hole 15 of an appropriate size for each construction site and use it, as well as to conveniently replace the used marking body 10 and use the required standard. Only the marking body 10 of the can be selectively connected and used.

Through this, it is possible to significantly increase the convenience and efficiency of the work, and there is an advantage that the cost for replacing the consumed product can also be significantly reduced compared to the case where a plurality of marking bodies are integrally formed.

Next, the insertion display unit 20 according to an embodiment of the present invention may be formed to be reused by repeatedly filling the solution.

The reason why the insertion display unit 20 is filled with the solution as described above is that the filled solution is gradually consumed after the insertion display unit 20 and the lubricant application unit 30 use a predetermined number of times.

For this purpose, as shown in FIG. 6 , the marking body 10 communicates between the outer circumferential surface and the insertion display unit 20 to fill the solution used to mark the insertion position of the pipe 1 , a display solution filling unit 25 ) is formed, and the filling part closing cap 26 formed to prevent the inflow of external air by covering the display solution filling part 20 so as to be hermetically sealed is installed on the outer peripheral surface of the marking body 10 to be detachably installed.

As such, when the solution filled in the insertion display unit 20 is consumed by repeating the operation of marking the insertion titration line 21 on the pipe 1 to be connected to the connection socket 2 several times, the display solution filling unit 20 is partially or After separating the filling part closing cap 26 from the marking body 10 so as to be fully exposed, it is injected so that the solution is filled into the insertion display part 20 through the display solution filling part 20 .

Accordingly, when the solution filled in at least one of the insertion display unit 20 or the lubricant application unit 30 is exhausted, the corresponding marking body 10 is discarded and replaced with a new product. By preventing the increase in construction cost due to processing and replacement of consumables, it is possible to reduce the overall construction cost bh required for the pipe (1) connection work.

Here, the reason why the marking body 10 is formed so that only the insertion display unit 20 can be repeatedly filled with the solution is that the lubricant application unit 30 is located deeper than the insertion display unit 20, but compared to the insertion display unit 20 This is because, as it occupies a large area, it is more efficient to fill the lubricant application unit 30 with the lubricant at the inlet side of the pipe insertion hole 15 .
