Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and more specifically, to a diversion-enhanced tee fitting. Background Technology

[0002] Tees are a type of pipe fitting, primarily used to connect to pipes and facilitate fluid flow. Tees are also known as pipe tees, tee fittings, or tee connectors. They are generally made of materials such as carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon-bonded asphalt, and PVC. For tees manufactured using seamless pipe, the common processes are hydraulic bulging and hot pressing. Based on the connection method, they can be classified as butt-welded tees, socket tees, compression fitting tees, and threaded tees.

[0003] The existing tee fittings have the following problems when in use: In order to switch the outlets of the two ends of the tee fitting, a pipeline valve needs to be installed at both ends of the outlet of the tee fitting, and a pipeline valve also needs to be installed at the inlet end of the tee fitting. The application of a large number of pipeline valves on the tee fitting will increase the design cost, and the subsequent disassembly and maintenance of the valves will be more difficult.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a diversion-enhanced tee fitting in order to achieve a more practical purpose. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can address the high cost of diversion and switching in tee fittings.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a diversion-enhanced tee fitting, comprising a horizontal pipe I, a vertical pipe at the top of the horizontal pipe I, horizontal pipe II at both ends of the horizontal pipe I, and pipe seats at opposite ends of each pair of horizontal pipe II. The pipe seats extend into the horizontal pipe I, a sealing bevel is provided at one end of the pipe seat, a through hole is provided in the pipe seat, a sealing plate body is provided inside the horizontal pipe I, the sealing plate body is in movable contact with the sealing bevel, and a sealing plate driving mechanism is provided on the horizontal pipe I and the sealing plate body.

[0007] In a preferred embodiment, the pipe fitting is connected to the second horizontal pipe via a flange, and the first horizontal pipe is connected to the pipe fitting via a flange.

[0008] In a preferred embodiment, the pipe fitting is connected to the second horizontal pipe via a flange, and the first horizontal pipe is connected to the pipe fitting via a flange.

[0009] In a preferred embodiment, a sealing groove is provided on the sealing bevel, and a metal skeleton rubber sealing ring that matches the sealing groove is fixedly connected to the end face of the sealing plate body.

[0010] In a preferred embodiment, one end of the pipe seat is provided with a pressure-reducing groove, and one end of the pressure-reducing groove is connected to the sealing groove.

[0011] In a preferred embodiment, the sealing plate body includes a seat seal, and the surface of the seat seal is provided with an anti-corrosion coating and a wear-resistant layer from the inside to the outside.

[0012] In a preferred embodiment, the sealing plate driving mechanism includes a drive shaft rotatably connected inside the horizontal tube, the sealing plate body and the drive shaft are connected by bolts, and a self-locking motor is mounted on the outside of the horizontal tube. The output shaft of the self-locking motor passes through the horizontal tube and is fixedly connected to one end of the drive shaft.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This diversion-enhanced tee fitting uses a pair of pipe seats mirrored at the vertical connection between the longitudinal pipe and a pair of horizontal pipes. By controlling the flipping movement of the sealing plate body, the sealing plate body can quickly achieve pressure sealing with the sealing slope corresponding to the pair of pipe seats. This allows for rapid switching of fluid flow between the pair of horizontal pipes, effectively reducing the cost of switching the tee fitting.

[0015] 2. This diversion-enhanced tee fitting has a pipe seat connected between horizontal pipe one and horizontal pipe two via a flange, and the sealing plate body is bolted to the drive shaft. Since the sealing plate body and the pipe seat are connected by a contact seal, both the sealing plate body and the pipe seat can be disassembled independently, which is convenient for maintenance and disassembly.

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See also Figures 1-5 This utility model provides a diversion-enhanced tee fitting, including a horizontal pipe 1, a vertical pipe 2 at the top of the horizontal pipe 1, and horizontal pipes 3 at both ends of the horizontal pipe 1. A pipe seat 4 is provided at the opposite ends of a pair of horizontal pipes 3. The pipe seat 4 extends into the horizontal pipe 1. The pipe seat 4 is connected to the horizontal pipes 3 by a flange, and the horizontal pipe 1 is connected to the pipe seat 4 by a flange.

[0025] The longitudinal pipe 2 serves as the inlet pipe for the entire tee fitting, and an inlet valve can be installed on it. Both the horizontal pipe 1 and the horizontal pipe 3 serve as outlet pipes. The pipe fitting seat 4 can be used as a hub channel for fluid control. Since the pipe fitting seat 4 is connected between the horizontal pipe 1 and the horizontal pipe 3 through a flange, the flange connection method facilitates the disassembly and assembly of the pipe fitting seat 4, and makes it convenient for the inspection and maintenance of the pipe fitting seat 4. It is worth noting that when the tee fitting is connected to the pipeline through a flange, the flange must be used in combination with the existing gasket.

[0026] In this embodiment: a sealing bevel 5 is provided at one end of the pipe seat 4, a sealing plate body 7 is provided inside the horizontal pipe 1, a sealing groove 10 is provided on the sealing bevel 5, and a metal skeleton rubber sealing ring 12 that matches the sealing groove 10 is fixedly connected to the end face of the sealing plate body 7.

[0027] Since there are two sets of pipe fittings 4, when it is necessary to independently control the two horizontal pipes 3 to block the fluid, the sealing slope 5 is set at an inclination. The sealing plate body 7 can be pressed and sealed with the sealing slope 5 by flipping and rotating the cover. When the sealing plate body 7 and the sealing slope 5 reach a relatively parallel state, the metal skeleton rubber sealing ring 12 can be pressed into the sealing groove 10. The existing metal skeleton rubber sealing ring 12 takes into account both sealing performance and pressure resistance and durability. In this way, the connection between the sealing plate body 7 and the sealing slope 5 can achieve a sealing effect.

[0028] In this embodiment: a through hole 6 is provided in the pipe seat 4, the through hole 6 is disposed through the pipe seat 4, and a metal filter screen 13 is fixedly connected to the inner wall of the through hole 6.

[0029] The position of the through hole 6 can be used to connect the horizontal pipe 1 and the horizontal pipe 3. When the sealing plate body 7 is pressed on the sealing slope 5, the sealing plate body 7 set on the sealing slope 5 can block the through hole 6 to prevent the fluid from flowing through this position. The metal filter screen 13 set in the through hole 6 can intercept impurities. Since the pipe seat 4 is connected by a flange, it is easy to disassemble and assemble, so the metal filter screen 13 can be easily cleaned.

[0030] In this embodiment, a pressure-reducing groove 11 is provided at one end of the pipe seat 4, and one end of the pressure-reducing groove 11 is connected to the sealing groove 10.

[0031] The pressure relief groove 11 provides a pressure relief channel for the sealing groove 10. When the metal skeleton rubber sealing ring 12 is pressed into the sealing groove 10, and when the tee fitting is conveying fluid, fluid will accumulate in the sealing groove 10. The pressure relief groove 11 can facilitate the expulsion of fluid, thereby reducing the resistance of the metal skeleton rubber sealing ring 12 being pressed into the sealing groove 10.

[0032] In this embodiment: a sealing plate body 7 is provided inside the horizontal tube 1. The sealing plate body 7 is in active contact with the sealing inclined surface 5. The sealing plate body 7 includes a seat seal 71. The surface of the seat seal 71 is provided with an anti-corrosion coating 72 and a wear-resistant layer 73 from the inside to the outside.

[0033] The anti-corrosion coating 72 and the wear-resistant layer 73 are respectively polyamide vertical material and alumina ceramic composite material. The anti-corrosion coating 72 and the wear-resistant layer 73 can strengthen the seat seal 71, so that the seat seal 71 can have effective anti-corrosion and wear-resistant effects, thereby improving the durability of the seal body 7 and the sealing bevel 5.

[0034] In this embodiment: a sealing plate driving mechanism is provided on the horizontal tube 1 and the sealing plate body 7. The sealing plate driving mechanism includes a driving shaft 8, which is rotatably connected inside the horizontal tube 1. The sealing plate body 7 and the driving shaft 8 are connected by bolts. A self-locking motor 9 is mounted on the outside of the horizontal tube 1. The output shaft of the self-locking motor 9 passes through the horizontal tube 1 and is fixedly connected to one end of the driving shaft 8.

[0035] In this application, the self-locking motor 9 can be fixed on the horizontal tube 1 by a motor mount. The self-locking motor 9 is electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer for control, and the existing public power connection technology will not be described in detail here. In this application, a gap is reserved between a pair of pipe seats 4. The gap position is the setting position of the drive shaft 8. The diameter of the pipe seat 4 is smaller than the diameter of the horizontal tube 1, and the diameter of the sealing plate body 7 is also smaller than the diameter of the horizontal tube 1. In this way, the sealing plate body 7 can rotate within the horizontal tube 1.

[0036] By activating the self-locking motor 9, the self-locking motor 9 can drive the drive shaft 8 to rotate. The rotation of the drive shaft 8 can drive the sealing plate body 7 to perform a flipping motion until the sealing plate body 7 is in horizontal contact with one of the sealing inclined surfaces 5. Then the through hole 6 on the pipe seat 4 can be blocked. Because the sealing plate body 7 uses a flipping method to seal and press the pipe seat 4, a pair of through holes 6 can be quickly switched on and off. Compared with the on and off control achieved by independent valves, this can significantly reduce the cost of use.

[0037] Since the sealing plate body 7 is connected to the drive shaft 8 by bolts, after the pipe seat 4 is disassembled and removed, the sealing plate body 7 can be exposed at the position of the horizontal pipe 1. The sealing plate body 7 can be easily removed for maintenance by removing the bolts.
