Description

Technical Field

[0001] This utility model relates to the technical field of tee connection fittings, specifically to a stainless steel gas pipeline tee connection fitting. Background Technology

[0002] Pipeline transportation is the mainstream mode of gas transportation worldwide. Gas pipeline networks serve as a bridge connecting long-distance pipelines and users. In gas pipeline installation, tee fittings are often used to connect branch pipelines to the main pipeline. Branch pipelines are directly connected to gas appliances for combustion.

[0003] Existing stainless steel gas pipeline tee fittings, while allowing two gas pipeline sections to be connected by setting first and second connecting threads on the outer walls of both ends of the main pipe, often use sealing rings to prevent gas leakage at the pipe connection. However, the sealing rings only seal the connection to prevent gas leakage, resulting in poor sealing performance. Therefore, there is an urgent need for a new type of stainless steel gas pipeline tee fitting to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a stainless steel gas pipeline tee connection fitting with better sealing effect, based on the current state of the technology.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a stainless steel gas pipeline tee connector, including a main pipe, with a first connecting pipe diameter and a second connecting pipe diameter at both ends of the main pipe. The outer walls of both ends of the main pipe are provided with a first connecting thread and a second connecting thread. A first ferrule and a second ferrule are installed on the main pipe behind the first connecting thread and the second connecting thread. A clamp is fixed on the bottom of the first ferrule and the second ferrule. A sealing gasket is provided on the inner wall of the clamp. A fixing block and a connecting block are fixed on each clamp. A clamp strip is connected around the clamp between the fixing block and the connecting block. The end of the clamp strip is provided with a clamping thread. A clamping bolt is connected to the clamp strip located at the connecting block.

[0008] Furthermore, a branch pipe is installed at the center of the top of the main pipe, a connector is fixed at the top of the branch pipe, a third connecting pipe diameter is provided on the connector, and marking panels are provided on both sides of the main pipe at the branch pipe.

[0009] By adopting the above technical solution, the main pipe can more firmly fix the branch pipe, and the main pipe and the branch pipe can better form a tee fitting.

[0010] Furthermore, both the first connecting pipe diameter and the second connecting pipe diameter are formed on the main pipe, which is made of stainless steel.

[0011] By adopting the above technical solution, the first connecting pipe diameter and the second connecting pipe diameter can facilitate gas transportation, allowing gas to be better introduced into the main pipe.

[0012] Furthermore, the main pipe and the connector are both welded to the branch pipe, the third connecting pipe is threaded inside the connector, and the marking panel is welded to the main pipe.

[0013] By adopting the above technical solution, the third connecting pipe diameter can make it easier to install the pipe on the connector, and the main pipe can more securely fix the marking panel.

[0014] Furthermore, both the first connecting thread and the second connecting thread are formed on the outer walls of both ends of the main tube, and both the first ferrule and the second ferrule are welded to the main tube.

[0015] By adopting the above technical solution, the first connecting thread and the second connecting thread can more easily install the pipe at both ends of the main pipe, and the main pipe can more firmly fix the first clamp and the second clamp.

[0016] Furthermore, both the first and second ferrules are welded to the clamp, which is made of a flexible metal material and is bonded to the sealing gasket.

[0017] By adopting the above technical solution, the first and second ferrules can more securely fix the clamp, the clamp can better fix the sealing gasket, and the sealing gasket can seal with the outer wall of the pipe connection, thereby improving the sealing effect of the pipe connection.

[0018] Furthermore, both the fixing block and the connecting block are welded to the hoop, and the hoop bar is bolted to the fixing block.

[0019] By adopting the above technical solution, the hoop can more firmly fix the fixing block and the connecting block, and the fixing block can make the hoop strip steadily wrapped around the outer wall of the hoop.

[0020] Furthermore, the hoop is wound around the outer wall of the hoop plate, the hoop is slidably connected to the connecting block, and the tightening thread is formed on the hoop.

[0021] By adopting the above technical solution, the clamp can slide on the connecting block when tightened, thereby making the clamp firmly tighten on the outer wall of the pipe connection.

[0022] Furthermore, the clamping bolt is connected to the clamping threaded bolt, and the clamping bolt is made of stainless steel.

[0023] By adopting the above technical solution, the clamping bolt and the clamping thread can better tighten the clamping bar, and the connecting block can better hold the clamping bolt in place.

[0024] (III) Beneficial Effects

[0025] Compared with the prior art, this utility model has the following advantages:

[0026] To address the issue that existing stainless steel gas pipeline tee fittings often use sealing rings to prevent gas leakage at pipe connections, but these rings only seal the connection and thus provide a poor seal, this invention addresses this problem by installing clamps on the first and second clamping sleeves. When the two pipes are threaded onto the first and second connecting pipe diameters respectively, tightening the clamping bolt causes the clamp to tighten on the clamp, which in turn causes the clamp to press the sealing gasket tightly against the outer wall of the pipe connection, thus sealing the connection and improving the overall sealing effect.
