Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to a reducing tee pipe connection device. Background Technology

[0002] Reducing tees are common and essential fittings in industrial piping systems, used to connect and branch pipes of different diameters. Their design aims to effectively meet fluid transport needs while ensuring system sealing and stability. The main characteristic of a reducing tee is its three channels, one of which has a different diameter than the other two. It is typically used to connect the main pipe to a branch pipe, thereby distributing fluid. Reducing tees can be manufactured from various materials, such as stainless steel, carbon steel, and plastic, depending on the application and medium. As an indispensable component of piping systems, reducing tees play a vital role in various industrial fields due to their unique structure and function.

[0003] However, most existing reducing tee pipe connection devices still require sealing at the connection point with a gasket during use. However, the gasket is prone to aging, hardening, or cracking over time, leading to a decrease in sealing effect. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a reducing tee pipe connection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reducing tee pipe connection device includes a connecting pipe with three flow guide grooves inside, all of which are arc-shaped. Four first receiving grooves are formed on one side of each of the three flow guide grooves. Three vents are formed on the surface of each of the four first receiving grooves away from the flow guide grooves. A second receiving groove is formed on the surface of each of the three vents away from the first receiving grooves. A second airbag is installed inside the second receiving groove, and the second airbag communicates with the vents. An expansion mechanism for inflating the second airbag is provided inside each of the four first receiving grooves. A connecting plate is fixedly connected to the end of the connecting pipe near the three second airbags. Four bolts are slidably connected to one side of each of the three connecting plates. Locking holes are formed on the surface of each of the four bolts near the first receiving grooves, and restraining mechanisms for constraining the bolts are provided inside each of the four locking holes. The second airbags prevent leakage between the pipe and the connecting pipe.

[0007] As a further embodiment of this utility model, the expansion mechanism includes a first airbag fixedly connected inside a first storage groove. The first airbag and a second airbag are configured to cooperate with each other. A pressure plate is slidably connected inside the first airbag. Two support rods are fixedly connected to the surface of the pressure plate near the second airbag. Both support rods are slidably connected to one side inside the first storage groove. Springs are sleeved on the surface of both support rods. One end of each spring is fixedly connected to one side inside the first storage groove, and the other end of each spring is fixedly connected to one side of the pressure plate. By setting the first airbag, the second airbag can be expanded.

[0008] As a further embodiment of this utility model, the constraint mechanism includes a slide groove, which is opened on one side of the connecting pipe. A piston groove is opened on the surface of the slide groove near the first receiving groove, and the piston groove and the first receiving groove are interconnected. A limit rod is fixedly connected inside the piston groove near the lock hole. A piston post is sleeved on the surface of the limit rod, and the piston post is configured to cooperate with the lock hole. A tension spring is sleeved on the surface of the limit rod. One end of the tension spring is fixedly connected to one side of the piston post, and the other end of the tension spring is fixedly connected to one side inside the piston groove. The bolt can be constrained by the setting of the piston post.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model employs a sealing solution using an airbag to seal the pipeline, thus preventing leakage between the pipeline and the connecting pipe. This effectively solves the problem of the sealing gasket aging, hardening, or cracking over time, leading to a decrease in sealing performance. When water is supplied, the water pressure compresses the first airbag through the guide channel, causing it to contract. A vent is installed at the bottom of the first airbag, communicating with the second airbag. Therefore, when water pressure compresses the first airbag, all the gas inside the first airbag is injected into the second airbag, causing it to expand. The expanded second airbag then contacts the pipeline, preventing leakage. Attached Figure Description

Each of the three vents 106 has a second receiving groove 105 on the surface of the side away from the first receiving grooves 104. A second airbag 201 is installed inside the second receiving groove 105, and the second airbag 201 is connected to the vent. The four first storage slots 104 are interconnected, and each of them has an expansion mechanism for inflating the second airbag 201. The end of the connecting pipe 1 near the three second airbags 201 is fixedly connected to a connecting plate 3. Each of the three connecting plates 3 is slidably connected to one side of the connecting pipe 3. Each of the four bolts 301 near the first storage slot 104 has a locking hole 302. Each of the four locking holes 302 has a restraining mechanism for restraining the bolts 301. The second airbags 201 can prevent leakage between the pipe and the connecting pipe 1.

[0019] Preferably, the expansion mechanism includes a first airbag 2 fixedly connected inside a first storage groove 104. The first airbag 2 and a second airbag 201 are configured to cooperate with each other. A pressure plate 203 is slidably connected inside the first airbag 2. The pressure plate 203 can be used to reset the first airbag 2. Two support rods 204 are fixedly connected to the surface of the pressure plate 203 near the second airbag 201. Both support rods 204 are slidably connected to one side inside the first storage groove 104. Springs 205 are sleeved on the surface of both support rods 204. One end of each spring 205 is fixedly connected to one side inside the first storage groove 104, and the other end of each spring 205 is fixedly connected to one side of the pressure plate 203. The first airbag 2 can be used to inflate the second airbag 201.

[0020] Preferably, the constraint mechanism includes a slide groove 101, which is formed on one side of the connecting pipe 1. A piston groove 102 is formed on the surface of the slide groove 101 near the first receiving groove 104, and the piston groove 102 and the first receiving groove 104 are interconnected. A limit rod 304 is fixedly connected inside the piston groove 102 near the lock hole 302. A piston post 303 is sleeved on the surface of the limit rod 304, and the piston post 303 is configured to cooperate with the lock hole 302.

[0021] Working principle: In use, the connecting pipe 1 is inserted into the corresponding pipe. After insertion, the pipe is then connected to the connecting pipe 1 using bolts 301. The connecting pipe 1 has a guide groove 103 on one side at each of the three connection points, and a first airbag 2 is installed inside the guide groove 103. When water is supplied, the water pressure compresses the first airbag 2 through the guide groove 103, causing it to contract. A vent 106 is installed at the bottom of the first airbag 2, and the vent 106 is connected to the second airbag 201. Therefore, when the water pressure compresses the first airbag 2, all the gas inside the first airbag 2 is injected into the second airbag 201, causing the second airbag 201 to expand. The second airbag 201 will contact the pipe to prevent leakage. The connecting pipe 1 has a piston groove 102 on the side near the bolt 301. A piston rod 303 is slidably connected inside the piston groove 102 and cooperates with the piston groove 102. Since the piston groove 102 is connected to the first receiving groove 104, when the first airbag 2 contracts, gas will also enter the piston groove 102, thereby moving the piston rod 303. The bolt 301 has a locking hole 302 on one side of the piston rod 303, so that the piston rod 303 will enter the bolt 301 as it moves, thereby achieving the purpose of restraining the bolt 301 and preventing it from loosening during use.
