Description

Technical Field

[0001] The utility model relates to a Y-shaped three-way assembly and a connection structure between the Y-shaped three-way assembly and a pipeline during specific application, belonging to the technical field of pipeline joints. Background Art

[0002] The Y-type tee is a commonly used pipe connector. Its name comes from its shape resembling the letter "Y". It is usually used in piping systems to divert fluid from one pipe to two different pipes, or to merge fluid from two pipes into one pipe. The design of the Y-type tee allows the fluid to maintain low resistance during the diversion or converging process, which contributes to the efficient operation of the fluid system.

[0003] This type of pipe connector is usually made of various materials, such as metal, plastic or other composite materials, to meet the needs of different industrial applications. When selecting and installing, factors such as the pipe material, fluid properties, working pressure and temperature need to be considered to ensure the safety and efficiency of the Y-type tee.

[0004] Traditional three-way pipe joints are usually connected and fixed to corresponding pipes by welding, but it is easy to weld through or weld blockage during the welding process, which will cause damage to the pipeline and waste. In addition, the welding method is time-consuming, labor-intensive and inefficient. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a Y-shaped three-way component which can facilitate the rapid assembly of a pipeline system and effectively ensure the connection reliability.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a Y-shaped tee assembly, including a tee body with three pipe interfaces, at least one pipe interface is a plug-in pipe interface, and the tee body is provided with an anti-falling assembly corresponding to the plug-in pipe interface one by one. Each anti-falling assembly includes a clamp, a base, a wire drum, a rope and a bolt. The base is fixedly arranged on the tee body, and a bolt column is fixedly arranged on the base. The bolt and the bolt column are matched and connected, and the wire drum is sleeved on the outer circumference surface of the bolt column. Ropes are respectively connected to both sides of the clamp, and one end of the rope away from the clamp is connected to the wire drum. When the bolt is in a loosened state or a separated state relative to the bolt column and the wire drum, the wire drum can rotate around the bolt column and allow the rope to be wound around the wire drum. When the bolt is in a tightened state relative to the bolt column and the wire drum, the bolt presses the wire drum tightly and fixes it to the base.

[0007] It is further preferred that: the three pipe interfaces are all plug-in pipe interfaces.

[0008] It is further preferred that the tee body includes an arc-shaped connecting section, the two pipe ends of the arc-shaped connecting section are respectively connected to extension sections as pipe interfaces, the outer side of the elbow of the arc-shaped connecting section is connected to a sleeve section as a pipe interface, and the axes of the two extension sections and the axis of the sleeve section are parallel to each other and located in the same horizontal plane.

[0009] It is further preferred that: the outer end pipe opening of the sleeve section is coaxially connected to the expansion section; the outer end pipe openings of the two extension sections are coaxially connected to the closing section.

[0010] It is further preferred that the clamp includes two symmetrically arranged clamping members, the butt joints of the two clamping members are fixedly connected by locking bolts, and the rope is connected to the butt joints of the two clamping members.

[0011] It is further preferred that a rubber pad is provided on the inner peripheral surface of the clamp.

[0012] It is further preferred that an external hexagonal interface is provided at one end of the wire reel away from the connection point between the base and the tee body, and the external hexagonal interface of the wire reel is equipped with a detachable external hexagonal cap.

[0013] Correspondingly, the utility model also provides a connection structure between the above-mentioned Y-shaped tee assembly and the pipeline during specific application implementation. The clamp is sleeved on the outer peripheral surface of the pipeline connection port and fixedly arranged. When the bolt presses the wire reel to the base, the rope is in a tensioned state between the wire reel and the clamp, and the plug-in pipeline interface of the tee body forms an interference fit with the pipeline.

[0014] The beneficial effects of the present invention are as follows: the Y-shaped tee in the present invention adopts a plug-in pipe interface to connect with the pipe and form an interference fit, which enables the device to be quickly installed in the pipe system, saves time and effort, effectively improves installation efficiency, and avoids welding blockage caused by welding; the present invention is also designed with an anti-falling component. After the pipe is connected, the rope is in a tightened state between the reel and the clamp, which can effectively prevent the pipe from falling off and causing water leakage or air leakage.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 and Figure 2 As shown, the Y-shaped tee assembly described in the present invention includes a tee body with three pipe interfaces, at least one pipe interface is a plug-in pipe interface, and the tee body is provided with an anti-falling assembly corresponding to the plug-in pipe interface one by one. Each anti-falling assembly includes a clamp 7, a base 8, a wire drum 9, a rope 10 and a bolt 11. The base 8 is fixedly arranged on the tee body, and a bolt column is fixedly arranged on the base 8. The bolt 11 and the bolt column are matched and connected, and the wire drum 9 is sleeved on the outer circumferential surface of the bolt column. Ropes 10 are respectively connected to both sides of the clamp 7, and one end of the rope 10 away from the clamp 7 is connected to the wire drum 9. When the bolt 11 is in a loosened state or a separated state relative to the bolt column and the wire drum 9, the wire drum 9 can rotate around the bolt column and make the rope 10 wound around the wire drum 9. When the bolt 11 is in a tightened state relative to the bolt column and the wire drum 9, the bolt 11 presses the wire drum 9 tightly and fixes it to the base 8. The connection between the bolt 11 and the bolt column can be understood in a broad sense. In the embodiment shown in the figure, the bolt column is in the form of an internally threaded hole that matches the bolt 11. In some alternative embodiments, the bolt column can also be configured as a partially externally threaded rod, and the bolt 11 can be in the form of a nut to achieve compression and fixation of the wire drum 9.

[0020] When the Y-type tee assembly described in the present invention is implemented in a specific application, it is only necessary to put the clamp 7 on the outer peripheral surface of the pipe 6 connection port and fix it, and then connect the plug-in pipe interface of the tee body to the pipe 6 accordingly. According to the actual situation, the pipe 6 can be inserted into the inner wall of the pipe interface of the tee body, or the pipe interface of the tee body can be inserted into the inner wall of the connection port of the pipe 6. It is only necessary to ensure that when the pipeline is connected, the plug-in pipe interface of the tee body and the pipe 6 form an interference fit. It is understandable that when the plug-in pipe interface of the tee body and the pipe 6 form an interference fit, it is only necessary that the material of any one of them has a certain ductility. Those skilled in the art can flexibly select the material according to the actual situation. For example, when the present invention is applied to the field of air conditioning, it mainly involves the connection of copper pipes. The tee body and the pipe 6 are both made of copper material, which can more conveniently achieve an interference fit between the plug-in pipe interface of the tee body and the pipe 6.

[0021] The main function of the anti-falling component designed in the present invention is to prevent the pipe 6 from falling off from the pipe interface of the tee body during use. Correspondingly, in the use state, the bolt 11 presses and fixes the wire drum 9 on the base 8. At this time, the rope 10 is in a tensioned state between the wire drum 9 and the clamp 7 to prevent the pipe 6 from falling off.

[0022] It is understood that the key technical point of the present invention is the use of plug-in pipes instead of traditional welding. As long as any one of the pipe joints is a plug-in pipe joint, it can improve assembly efficiency to a certain extent. Unless there are special circumstances, the present invention generally prefers to design all three pipe joints as plug-in pipe joints. Accordingly, each plug-in pipe joint is equipped with an anti-drop assembly.

[0023] To maintain low resistance during fluid diversion or convergence, thus facilitating efficient fluid system operation, the preferred structure of the tee body includes an arcuate connecting section 1. The two pipe ends of the arcuate connecting section 1 are each connected to an extension section 2 as a pipe interface. The outer side of the elbow of the arcuate connecting section 1 is connected to a sleeve section 4 as a pipe interface. The axes of the two extension sections 2 and the sleeve section 4 are parallel and coplanar. The axis of the arcuate connecting section 1 is preferably a semicircular structure.

[0024] To further facilitate pipeline connection, the outer end of the sleeve section 4 is coaxially connected to the expansion section 5; the outer end of the two extension sections 2 is coaxially connected to the closing section 3.

[0025] The clamp 7 is an existing mature technology. In order to facilitate the connection of the rope 10, the preferred solution is that the clamp 7 includes two symmetrically arranged clamping parts, and the two ends of the two clamping parts are fixedly connected by locking bolts (that is, the two ends of the two clamping parts are equivalent to having connecting plates for connecting the locking bolts at the two ends of the two clamping parts). The rope 10 is connected to the two ends of the two clamping parts. The rope 10 can be directly connected to the above-mentioned connecting plate or directly connected to the above-mentioned locking bolt. Generally, a rope ring can be set at the end of the rope, and the locking bolt is used to pass through the rope ring to achieve connection.

[0026] The inner circumferential surface of the clamp 7 is preferably provided with a rubber pad 13 , which, on the one hand, plays an anti-slip role, and on the other hand, prevents the clamp 7 from crushing the pipe 6 .

[0027] In order to facilitate the driving of the wire drum 9 to rotate around the bolt column on the base 8, an external hexagonal interface is provided at one end of the wire drum 9 away from the connection point between the base 8 and the tee body, and the external hexagonal interface of the wire drum 9 is equipped with a detachable external hexagonal cap 12.

[0028] It is understandable that the dimensions of the various components of the Y-type tee can be flexibly designed according to actual conditions. For example, in a preferred embodiment of the present invention, the central axis radius of the arc-shaped connecting section 1 is 9.52 cm, the outer diameter of the extension section 2 is 5.0 ± 0.1 cm, the length of the closing section 3 is 6 cm, the outer diameter of the closing section 3 is 4.45 ± 0.1 cm, the vertical spacing between the central axes of the two closing sections 3 is 19 ± 0.1 cm, the total length of the entire Y-type tee is 38 ± 1 cm, the inner diameter of the sleeve section 4 is 5 + 0.26 / + 0.11 cm (i.e., 5.11 cm to 5.26 cm), the length of the flaring section 5 is 0.5 cm, the angle of the flaring section 5 is 90 °, the insertion depth of the plug gauge is 5 + 1 / 0 cm (i.e., 5 cm to 6 cm), and the total length of the sleeve section 4 and the flaring section 5 is 9 cm. The preferred assembly process is to first use a plug gauge to expand the sleeve section 4 during the interference fit installation process to facilitate installation.

[0029] After the pipe 6 is connected, the pipe 6 is connected to the outer wall of the closing section 3 and the inner wall of the sleeve section 4 respectively, and the pipe 6 is quickly installed and fixed. Then it can be used normally, avoiding the use of welding in the traditional way for fixing, which leads to the phenomenon of welding blockage and damage to the pipeline. Then the clamp 7 and the rubber pad 13 are installed on the pipe 6 together, and the rope 10 is put on the connection between the two sides of the clamp 7, and then the outer hexagonal cap 12 is inserted into the wire drum 9, and the outer hexagonal cap 12 is rotated. With the support of the base 8, the wire drum 9 starts to reel the rope 10, and the rope 10 pulls the clamp 7 to drive the pipe 6 to be tightened, and the closing section 3 or the sleeve section 4 is interference fit. Then the outer hexagonal cap 12 is pulled out, and then the bolt 11 is rotated to squeeze the bolt 11 downward and contact the top of the wire drum 9, and the wire drum 9 is firmly fixed to avoid loosening, thereby achieving the installation of the pipe 6 on the closing section 3 or the sleeve section 4 to prevent it from falling off.
