In the traditional technology of the pressure tapping pipe, after a tapping tool is used for tapping a certain part of a pipe fitting of a pipeline system, although a through hole can be formed on the wall of the pipe fitting, a large amount of chips are synchronously generated in the process of forming the through hole on the wall of the pipe fitting. The piece that produces will be detained inside the pipeline, and the pipeline is more and the pipe diameter is different based on pipe-line system is inside, especially to the less pipe fitting of pipe diameter, accumulates the piece very easily and takes place blocking phenomenon. In addition, the pipeline is easy to enter the machine table, so that the breakdown defect is caused.

Based on the above, referring to fig. 1 and fig. 3, fig. 1 shows a schematic structural diagram of a tapping operation of the pressurized tapping device of an embodiment, and fig. 3 shows a schematic structural diagram of a piping system 200 of a factory building of an embodiment. An area that this application embodiment provided presses trompil device, area press trompil device includes: a housing 110, an opening mechanism 120, and a drainage filter assembly 130. The housing 110 is provided with a docking portion 1101 for docking with a portion to be bored on the pipe 210. The tapping mechanism 120 is connected to the housing 110, and a tapping member (not shown) of the tapping mechanism 120 is disposed in the housing 110. The drainage filter assembly 130 is in communication with the housing 110, and the drainage filter assembly 130 is configured to filter debris from the fluid.

When the pipe fitting 210 of the pipeline system 200 is subjected to tapping operation, the butt-joint part 1101 is butted with a part to be tapped on the pipe fitting 210, then tapping is performed through the tapping member of the tapping mechanism 120, debris generated in the tapping process of the pipe fitting 210 flows into the drainage filter assembly 130 together with pressurized liquid leaked into the casing 110 from the tapping part, the pressurized liquid is filtered through the drainage filter assembly 130, and the debris is filtered, so that the debris is prevented from accumulating and entering the pipeline, the blockage phenomenon in the pipeline system 200 can be avoided, and the debris is prevented from entering the machine 230 along with the pipeline to cause downtime; meanwhile, the pipeline system 200 of the factory building does not need to be stopped, and the pipe fittings 210 of the pipeline system 200 of the factory building can be subjected to hole opening operation on line; the pressure tapping device is particularly suitable for tapping under pressure of pressure pipelines with small fluid supply pipe diameter, dense pipe networks and high supply quality requirements, reduces the entering of chips into the pipe networks, and reduces the downtime risk caused by the fact that the chips enter the machine table 230 along with the pipelines after tapping is completed.

Referring to FIG. 1, in one embodiment, the drainage filter assembly 130 is also adapted to communicate with a tubing system 200. Therefore, the debris generated in the hole opening process is guided into the drainage filter assembly 130 by using the fluid pressure difference, filtered by the drainage filter assembly 130 and returned to the pipeline system 200. Filtered liquid returns to the pipeline system 200 again, so that resource waste can be avoided, meanwhile, debris can be prevented from entering the pipeline system 200, and production risk is greatly reduced.

Specifically, the drainage filter assembly 130 is connected to a pipe with relatively low hydraulic pressure in the pipeline system 200, such as the water return pipe 220, so that the liquid can be drained out through the drainage filter assembly 130.

Of course, in an embodiment, the drainage filter assembly 130 is provided with a pump body (not shown in the drawings), and the pressure is provided by the pump body to make the liquid entering the interior of the housing 110 during the opening process be discharged outwards through the drainage filter assembly 130, in which case, the drainage filter assembly 130 can be connected with any pipe in the pipeline system 200 according to actual requirements, and is not limited herein.

Of course, as an alternative, the filtered liquid from the drainage filter assembly 130 can be discharged directly to the outside without being returned to the piping system 200.

Referring to fig. 1, in one embodiment, the docking portion 1101 is sealingly disposed at a portion to be perforated. Thus, in the process of opening the through hole at the to-be-opened position of the opening member of the opening mechanism 120, the pressurized liquid inside the pipe 210 enters the casing 110 through the through hole, and the abutting portion 1101 is hermetically arranged at the to-be-opened position, so that the pressurized liquid inside the casing 110 can be prevented from leaking outwards through the abutting portion 1101.

It should be noted that, there are various sealing arrangements of the docking portion 1101 on the portion to be perforated, which specifically include, but are not limited to, the following several arrangements: the butt-joint part 1101 is used for being welded and connected to a part to be perforated; or the butting part 1101 is used for being connected with a part to be punched in a clamping manner, and a sealing element is arranged between the butting part 1101 and the part to be punched so as to ensure the sealing property of the butting part 1101 and the part to be punched after the butting part 1101 and the part to be punched are connected in the clamping manner; or the butting part 1101 is provided with threads, the part to be perforated is provided with a screwed joint which is matched with the butting part 1101, and a sealing element is arranged between the butting part 1101 and the part to be perforated so as to ensure the sealing property after the butting part 1101 and the screwed joint of the part to be perforated are connected; alternatively, the abutting portion 1101 is used for being provided at a portion to be perforated by seal adhesive.

Referring to fig. 1, in one embodiment, the housing 110 is provided with a first valve 111. The first valve 111 can form a first chamber and a second chamber isolated from each other in the housing 110 when in a closed state. When the first valve 111 is in the open state, the first chamber and the second chamber are communicated with each other. Further, the first chamber communicates with the docking portion 1101. The aperture of the aperture mechanism 120 can extend into the first chamber and can retract into the second chamber. Thus, when the hole opening mechanism 120 performs hole opening operation on the to-be-opened hole part, the first valve 111 is opened, so that the hole opening piece of the hole opening mechanism 120 extends into the first chamber to perform hole opening operation on the to-be-opened hole part, and can conveniently pass through the butt joint part 1101 to directly contact the to-be-opened hole part and form a through hole on the to-be-opened hole part; after the portion of the pipe 210 to be perforated is machined to form the required through hole, the perforated part of the perforating mechanism 120 can be retracted into the second chamber, so that the perforated part is retracted into the second chamber, and the first valve 111 is closed, and the first valve 111 in the closed state can ensure the sealing performance of the through hole machined in the pipe 210.

In one embodiment, the first valve 111 includes, but is not limited to, a gate valve, a ball valve, or other valve body. Furthermore, the first valve 111 may be an electrically controlled valve, a pneumatically controlled valve, or a mechanical valve that is operated manually or mechanically by a drive, for example.

Referring to fig. 1, in one embodiment, the housing 110 includes a first housing 112 having a first chamber formed therein, and a second housing 113 having a second chamber formed therein. The first housing 112 is connected to the second housing 113 through the first valve 111. The first housing 112 has a docking portion 1101, and the tapping mechanism 120 is connected to the second housing 113.

It should be noted that the "second shell 113" may be a part of the "hole opening mechanism 120", that is, the "second shell 113" and the "other part of the hole opening mechanism 120" are integrally formed; or a separate member that can be separated from the other parts of the tapping mechanism 120, i.e., the second housing 113 can be manufactured separately and then combined with the other parts of the tapping mechanism 120 into a single body.

It should be further noted that, as an alternative, both the second housing 113 and the first housing 112 may also be non-detachable structures, for example, the "second housing 113" may be a "part of the first housing 112", that is, the "second housing 113" and the "other part of the first housing 112" are integrally manufactured; the "second housing 113" may be manufactured separately from the "other portion of the first housing 112" and then combined with the "other portion of the first housing 112" to form a single body.

Referring to fig. 1 and 2, fig. 2 is a schematic structural diagram illustrating a tapping operation of a tapping device with pressure according to another embodiment. The main difference between FIG. 2 and FIG. 1 is the attachment location of the drainage filter assembly 130 to the housing 110. Referring to fig. 1, in one embodiment, a pressure relief port is disposed on the first casing 112, and the drainage filter assembly 130 is in communication with the pressure relief port of the first casing 112. Alternatively, referring to fig. 2, a pressure relief interface is disposed on the second casing 113, and the drainage filter assembly 130 is communicated with the pressure relief interface of the second casing 113. In this way, the debris generated during the process of opening the hole in the pipe 210 and the pressurized liquid leaked from the hole position into the casing 110 can be directly discharged to the outside into the drainage filter assembly 130 through the pressure relief interface on the first casing 112, or can be directly discharged to the outside into the drainage filter assembly 130 through the pressure relief interface on the second casing 113.

Referring to fig. 1, in one embodiment, the first housing 112 is detachably connected to the first valve 111, and the first valve 111 is detachably connected to the second housing 113. Thus, in the process of installing the pressurized hole opening device on the to-be-opened part of the pipe 210, the first housing 112 may be installed on the to-be-opened part, then the first valve 111 is assembled and connected with the first housing 112, and then the second housing 113 is assembled and connected with the first valve 111, so that the pressurized hole opening device is gradually installed on the to-be-opened part of the pipe 210; conversely, when it is desired to remove the pressurized tapping device from the tubular 210, the operation steps for removing the device may be reversed, for example, from the operation steps for assembling the device. So, can be convenient for realize carrying out dismouting operation with the area pressure trompil device on the part of treating the trompil of pipe fitting 210. In addition, when the hole opening of the pipe 210 is completed and the debris is filtered, the first valve 111 can be closed, the hole opening mechanism 120 and the second housing 113 can be removed, the first housing 112 and the first valve 111 remain on the pipe 210, and the water in the pipeline system 200 can be prevented from leaking out through the hole opening of the pipe 210 by the first valve 111. Of course, as an alternative, the opening mechanism 120 and the second housing 113 may also be retained on the piping system 200 of the plant.

Specifically, the first housing 112 is connected to one of the abutting ends of the first valve 111 by, for example, flanges, and a sealing ring is disposed between the flanges to ensure the sealing performance at the abutting position of the first housing 112 and the first valve 111. In addition, the second housing 113 is connected to the other abutting end of the first valve 111 by, for example, a flange, and a sealing ring is provided between the flanges to ensure the sealing performance at the abutting position of the second housing 113 and the second valve 133.

Of course, as an alternative, when the sealing performance of the housing 110 is good enough, the first valve 111 may be omitted, that is, the first valve 111 does not need to be disposed on the housing 110.

Referring to fig. 1, in an embodiment, the first housing 112 includes, but is not limited to, a short joint, and may also be a joint pipe 210 in other forms, and the specific form can be flexibly adjusted and set according to the user's requirement, as long as the first housing can be conveniently and sealingly connected to the position to be perforated on the pipe 210. When the first shell 112 is short, the first shell 112 can be welded to the to-be-perforated portion of the pipe 210, and the sealing performance between the first shell 112 and the outer wall of the pipe 210 after welding is guaranteed.

It should be noted that the specific shape of the first housing 112 is not limited herein, and may be, for example, a cylindrical tube shape, a square cylindrical tube shape, or the like. The specific shape of the second housing 113 is also not limited, and may be a cylindrical tubular shape, a square cylindrical tubular shape, or the like.

Referring to fig. 1, in one embodiment, the drainage filter assembly 130 includes a drainage tube 131 communicating with the housing 110, and a filter 132 disposed in series on the drainage tube 131. The filter 132 is used to filter out debris from the liquid.

Specifically, one end of the draft tube 131 communicates with the housing 110, and the other end of the draft tube 131 is used for, for example, tapping into the piping system 200.

Referring to fig. 1, in one embodiment, the drainage filter assembly 130 further includes a second valve 133. The second valve 133 is disposed in series on the draft tube 131. In this way, after the hole opening operation on the pipe 210 is finished, the second valve 133 can be closed to ensure the sealing performance at the through hole position on the pipe 210.

Referring to fig. 1, in one embodiment, the number of the second valves 133 is at least two, wherein one second valve 133 is disposed upstream of the filter 132, and the other second valve 133 is disposed downstream of the filter 132. Thus, after the filters 132 are used for a period of time, the filters 132 can be removed from the drain tube 131 and cleaned, maintained, replaced, etc. by closing one of the filters 132 located upstream of the filters 132 and one of the filters 132 located downstream of the filters 132. After the filter 132 is maintained and replaced, the second valve 133 is opened again. In addition, when the opening of the pipe 210 is completed and the debris is filtered, the second valves 133 at the upstream and downstream of the filter 132 can be closed and the filter 132 can be removed, so that the second valves 133 at the upstream and downstream of the filter 132 can prevent the water in the piping system 200 from leaking outwards. Of course, as an alternative, the filter 132 may also be retained on the plant piping system 200.

It should be noted that, the upstream of the filter 132 refers to a pipeline portion of the drainage tube 131 where the liquid flows into the filter 132, and the downstream of the filter 132 refers to a pipeline portion of the drainage tube 131 for receiving the liquid filtered by the filter 132.

It should be noted that the number of the second valves 133 illustrated in fig. 1 and fig. 2 is two, and fig. 1 and fig. 2 are only some embodiments, and when the second valves 133 are specifically arranged, for example, one, three, four or other numbers may also be used, which are not limited herein, and the number is set according to actual requirements.

In one embodiment, the opening mechanism 120 includes a punching mechanism, a milling mechanism, or a laser cutting mechanism. Thus, when the hole-opening mechanism 120 is a punching mechanism, the hole-opening member is a punching head, the punching head acts on the part to be opened with holes in a punching manner, and the part to be opened with holes is opened to form through holes; when the hole opening mechanism 120 is a milling mechanism, the hole opening member is a milling head, the milling head acts on the part to be opened by milling, and the part to be opened is provided with a through hole; when tapping mechanism 120 is laser cutting mechanism, the piece of holing is the laser head, and the laser head acts on the position of waiting to trompil through the mode of laser cutting to offer on waiting to trompil the position and form the through-hole.

Of course, the hole opening mechanism 120 is not limited to the three modes in the above embodiments, and may be set in other forms as long as a through hole can be formed on the portion to be opened, which is not limited herein, and may be flexibly adjusted and selected according to actual requirements.

In one embodiment, referring to fig. 1 or fig. 2, the specific tapping operation method of the pressurized tapping device shown in fig. 1 or fig. 2 is described in detail as follows:
