Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe joints, in particular to a quick installation gas taking joint device under pressure. BACKGROUND

[0002] In some engineering projects, it is often necessary to punch holes on the ventilation pipeline, then connect the joint and branch pipeline. The conventional operation needs to close the ventilation pressure valve, stop the pipeline gas supply, then punch holes, and then fix the joint and install the branch pipeline. This operation is time-consuming and laborious, and closing the ventilation pressure valve will also delay the gas supply of other equipment, which is very inconvenient. Therefore, a quick installation gas taking joint device under pressure is needed, which can install the joint first, then punch holes directly on the pipeline inside the joint, so that the punching and connecting the joint and installing the branch pipeline can be directly completed without closing the ventilation pressure valve.

However, using a drill bit on some thin-walled ventilation pipelines will cause deformation of the pipeline, affecting the service life of the pipeline, and how to install the branch pipeline after punching holes without affecting other equipment on the pipeline is also a problem that needs to be optimized.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Example 1:

[0033] For installing branch pipes on plastic ventilation ducts, the following are provided: Figures 1-4 The pressurized quick-connect gas intake device shown includes: a gas intake connector 1, a connecting connector 2, and an opening device 3. One end of the connecting connector 2 is connected to the gas intake connector 1, and the other end is connected to the opening device 3. The opening device 3 passes through the interior of the connecting connector 2 and the gas intake connector 1.

[0034] The connector 2 has an annular groove at each end and a second sealing ring 7 inside. To improve the sealing effect, the second sealing ring 7 is selected as a sealing ring with multiple seals.

[0035] The gas intake connector 1 includes a clamp 4, a first sealing ring 5, and a ball valve 6. The clamp 4 has an opening seat, and the first sealing ring 5 is tightly fitted inside the opening seat. One end of the ball valve 6 is inserted into the opening seat on the clamp 4, and the other end of the ball valve 6 has an annular protrusion on its outer wall. The annular protrusion mates with an annular groove on the connecting connector 2 for a secure connection. The annular protrusion on the ball valve 6 and the annular groove on the connecting connector 2 ensure a stable connection.

[0036] Two clamps 4 are provided, symmetrically fastened to the vent pipe. Each clamp 4 has a flange with through holes, through which bolts are passed to secure it. Each clamp 4 is equipped with a first sealing ring 5 and a ball valve 6.

[0037] The perforation device 3 includes a perforation tube 9, a fixed base 8, a drive block 10, a coupling 11, and a motor 12. The fixed base 8 is fixedly connected to the connecting joint 2. One end of the coupling 11 is connected to the drive block 10, and the other end is connected to the motor 12. The drive block 10 is movably connected to the fixed base 8. The perforation tube 9 is mounted on the drive block 10 and passes through the connecting joint 2 and the air intake joint 1. The second sealing ring 7 is tightly fitted with the perforation tube 9. A pipe perforation cutter 15 is located on the end face of the perforation tube 9. The coupling 11 converts the power provided by the motor 12 into torque to drive the drive block 10 to rotate, thereby driving the perforation tube 9 to rotate and cut a hole in the air intake pipe. For ease of use, a small, manually controlled motor 12 is selected. After the perforation tube makes a hole in the pipe, the second sealing ring 7 is tightly fitted with the perforation tube 9, sealing the gas within the ball valve 6 of the air intake joint 1. The pipe perforation cutter 15 is made of stainless steel and has a serrated shape. The drive block 10 and the perforated tube 9 can move along the axis of the fixed base 8.

[0038] The fixing base 8 includes an upper fixing base 14 and a lower fixing base 13. A screw is installed on the lower fixing base 13, and the upper fixing base 14 has a through hole. The screw passes through the through hole of the upper fixing base 14 and is fixed with a lock nut.

[0039] The outer wall of the fixed upper seat 14 has an annular flange, which mates with an annular groove in the connecting joint 2 for a secure connection. The engagement of the annular flange and the annular groove makes the connection more stable.

[0040] Working Principle: Install two clamps 4 on the ventilation pipe and secure them firmly with bolts. Open the valve of the ball valve 6 on one clamp 4, insert the opening device 3, and use the connecting connector 2 to fix the ball valve 6 and the fixing seat 8. Start the motor 12; the coupling 11 converts the power provided by the motor 12 into torque, driving the drive block 10 to rotate, thereby driving the opening pipe 9 to rotate. The pipe opening knife 15 on the end face of the opening pipe 9 cuts a hole in the ventilation pipe. After the hole is opened, because the second sealing ring fits tightly with the opening pipe 9, the gas in the ventilation pipe is sealed and will not leak. Pull the opening pipe 9 away from the pipe until the end of the second sealing ring 7 is close to the ball valve 6, close the valve of the ball valve 6, and seal the gas in the ventilation pipe inside the ball valve 6. At this time, remove the connecting connector 2 and the opening device 3, and install the branch pipe. After the branch pipe is installed, open the valve of the ball valve 6, and the gas in the ventilation pipe can flow through the branch pipe.

[0041] like Figure 5 As shown, repeat the above operation on another clamp 4 to open a second hole in the ventilation pipe and install a second branch pipe.
