Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic tee fitting technology, specifically a hydraulic tee fitting structure. Background Technology
[0002] In the early days of hydraulic system development, pipe connections were relatively simple. Traditional connections often suffered from poor sealing and leakage. With advancements in industrial technology, hydraulic systems required higher pressures and flow rates to support the operation of complex machinery such as engineering equipment and metallurgical equipment. Hydraulic tee fittings emerged to address this need. Early tee fittings were likely simple metal pipe fittings assembled through welding or threaded connections, but this method suffered from stress concentration and poor sealing.
[0003] Because the liquid cannot drain evenly from the connecting pipes at both ends during liquid transport, the diverter block acts as a buffer within the main body of the hydraulic tee connector to prevent excessive internal pressure from hindering even liquid distribution to both pipes. It is secured by fixing screws to prevent the diverter block from collapsing during liquid transport, thus ensuring even liquid drainage from both ends of the hydraulic tee connector. The two end connectors are connected to the pipes via a first connecting thread and a second connecting thread. A first washer and a second washer serve as the interface to prevent leakage, ensuring the efficient and stable operation of the hydraulic system. Utility Model Content
[0004] The purpose of this utility model is to provide a hydraulic tee connector structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic tee connector structure, comprising a hydraulic tee connector body, a nut connected to the top of the hydraulic tee connector body, a nut thread provided in the inner cavity of the nut, a flow divider block provided in the inner cavity of the hydraulic tee connector body, a fixing screw provided at the bottom of the flow divider block, a first top block provided in the inner cavity at one bottom end of the hydraulic tee connector body, and a first washer provided at one end of the first top block.
[0006] Preferably, the hydraulic tee connector has an interface thread on the top outer side of its main body, and the nut thread can be installed by mating with the interface thread.
[0007] Preferably, the connecting nut is threaded to the interface thread, and the diverter block is located in the middle of the inner cavity of the hydraulic tee connector body.
[0008] Preferably, the bottom of the diverter block is provided with a threaded hole, and the fixing screw passes through the threaded hole at the bottom of the hydraulic tee connector body.
[0009] Preferably, the first top block and the second top block are fixedly connected to the inner cavities at both ends of the bottom of the hydraulic tee connector body.
[0010] Preferably, the first washer and the second washer are detachably connected, and the first connecting thread and the second connecting thread are integrally connected to the hydraulic tee connector body.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This hydraulic tee connector structure involves screwing a connecting nut into the interface thread. The inner cavity of the connecting nut also has another half of the nut thread. The main pipe thread connects to the connecting nut, which serves to connect and seal the main pipe, preventing liquid leakage during transportation. The diverter block acts as a buffer within the main body of the hydraulic tee connector to prevent excessive internal pressure from causing uneven distribution of liquid to the two pipes. It is fixed by fixing screws to prevent the diverter block from collapsing during liquid transportation, thus ensuring even drainage of liquid from both ends of the hydraulic tee connector.
[0013] 2. The hydraulic tee connector structure has two ends that are connected to the pipe via a first connecting thread and a second connecting thread. The first and second washers serve as interfaces to prevent leakage. Due to the threaded connection, the threads are tightly connected, ensuring the airtightness of the pipe connection and preventing the risk of leakage during liquid transportation. Both washers can be easily replaced. The first and second top blocks act as limiters, preventing the pipe from being screwed into the deep cavity of the hydraulic tee connector body, thus improving the safety and sealing of the device.

The main pipe thread connects to the connecting nut 4, which serves as a connection and seal for the main pipe to prevent liquid leakage during transportation. The diverting block 5 serves as a buffer for the inner cavity of the hydraulic tee connector body 1 to prevent excessive internal pressure from causing uneven distribution to the pipes on both sides. It is fixed by the fixing screw 6 to prevent the diverting block 5 from being washed away during liquid transportation, thus achieving the purpose of evenly discharging liquid from the pipes at both ends of the hydraulic tee connector body 1.

Both washers can be easily replaced. The first top block 7 and the second top block 10 serve as a limit to prevent the pipe from being screwed into the deep cavity of the hydraulic tee connector body 1, thereby improving the safety and sealing of the device.

The main pipe thread connects to the connecting nut 4, which serves to connect and seal the main pipe to prevent liquid leakage during transportation. The diverter block 5 acts as a buffer in the inner cavity of the hydraulic tee connector body 1 to prevent excessive internal pressure from causing uneven distribution to the two pipes. It is fixed by the fixing screw 6 to prevent the diverter block 5 from being washed away during liquid transportation, thus ensuring even drainage of liquid from both ends of the hydraulic tee connector body 1. The two end connectors are connected to the pipes by the first connecting thread 9 and the second connecting thread 12. The first washer 8 and the second washer 11 serve as the interface to prevent leakage. Due to the threaded connection, the threads are tightly connected, which ensures the airtightness of the pipe connection and prevents the risk of leakage during liquid transportation. Both washers can be easily replaced.
