Description

Technical Field

[0001] The utility model relates to the field of two-way pipe joints, and more specifically, to an anti-aging thermoplastic equal-diameter two-way pipe joint. Background Art

[0002] An anti-aging thermoplastic equal-diameter two-way pipe joint is a pipe connection element made of special thermoplastic materials, which has excellent anti-aging performance and can maintain the stability of its physical and chemical properties during long-term use. At the same time, its equal-diameter design makes the sizes of the pipes connected at both ends the same, facilitating installation and fluid transmission, and is applicable to various pipe systems requiring high reliability and durability.

[0003] As known from the patent number 201910017584.6, a reinforced bite-type two-way pipe joint is disclosed, which includes an outer shell, bite teeth arranged inside the outer shell, and a sealing component. The sealing component includes an axially-sealing part, a first sealing semi-circle part and a second sealing semi-circle part which are integrally connected. Among them, the second sealing semi-circle part can block most of the water, greatly reducing the water pressure. Then when the water reaches the first sealing part, it is completely sealed. A connecting structure is also arranged at the corner of the sealing component, reducing the possibility of water leakage at the corner of the sealing component. And by arranging a diversion structure at the turning point, the diversion structure is made of an elastic material, which can buffer the water flow, thereby reducing the pressure caused by the water flow at the turning point, and guiding the direction of the water flow through the design of the diversion groove, reducing the possibility of water leakage.

[0004] In a household water system, two-way pipes are often used to connect water-using devices such as faucets, toilets, washing machines, etc., to ensure smooth water flow and meet the daily household water demand. After long-term use, due to reasons such as wear of internal components of the water pump, poor sealing or blockage, the drainage performance will gradually decline. When the performance of the water pump decreases, the water pressure provided by it will also become unstable. During high-pressure periods, the water flow may break through the seal of the closed water valve, resulting in water leakage. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an anti-aging thermoplastic equal-diameter two-way pipe joint to solve the deficiency of water leakage and facilitate use.

[0006] To achieve the above purpose, the technical solution provided by the utility model is as follows:

[0008] Preferably, an extrusion adjustment column is installed inside the lifting chamber, an extrusion ball is arranged at the top end of the extrusion adjustment column, and built-in reserved grooves are opened at the bottom ends of the extrusion adjustment column and the extrusion ball.

[0009] Preferably, an extension groove is provided on the inner end surface of the joint base, and the extension groove is communicated with the lifting chamber.

[0010] Preferably, a positioning pole is installed inside the extension groove, one end of the positioning pole extends upward to the inside of the built-in reserved groove, the outer end of the positioning pole is sleeved with a sleeve spring, the bottom end of the sleeve spring is connected to the inner bottom surface of the extension groove, the top end of the sleeve spring is connected to the upper top surface of the built-in reserved groove, and the length of the sleeve spring is greater than the positioning pole.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0024] Combined with Figure 1, an anti-aging thermoplastic equal-diameter two-way pipe joint of the present utility model, includes a central connection sleeve 1 and an equal-diameter pipe 2 arranged inside the central connection sleeve 1. The upper end of the central connection sleeve 1 is provided with a butt joint 3, and the butt joint 3 is docked with the output end of the water supply equipment. The lower end of the central connection sleeve 1 is installed with a joint base 4. The two ends of the equal-diameter pipe 2 are respectively docked with different pipelines. A horizontal pipe cavity 5 is opened inside the equal-diameter pipe 2, and a vertical pipe cavity 6 is opened inside the butt joint 3. The horizontal pipe cavity 5 and the vertical pipe cavity 6 are connected. A lifting cavity 7 is opened at the bottom end of the central connection sleeve 1.

[0025] The following further describes the present utility model in conjunction with embodiments.

[0026] Combined Figures 2 - 4 , an extrusion adjustment column 71 is installed inside the lifting cavity 7. The top end of the extrusion adjustment column 71 is provided with an extrusion sphere 72. An internal reserved groove 73 is opened at the bottom ends of the extrusion adjustment column 71 and the extrusion sphere 72. An extension groove 41 is opened on the inner end face of the joint base 4. The extension groove 41 is connected to the lifting cavity 7. A positioning vertical rod 74 is installed inside the extension groove 41. One end of the positioning vertical rod 74 extends upward into the internal reserved groove 73. A socket spring 75 is sleeved on the outer end of the positioning vertical rod 74. The bottom end of the socket spring 75 is docked with the inner bottom surface of the extension groove 41, and the top end of the socket spring 75 is docked with the upper top surface of the internal reserved groove 73. The length of the socket spring 75 is greater than that of the positioning vertical rod 74.

[0027] A matching arc groove 61 is opened at the corner end of the vertical pipe cavity 6 and the horizontal pipe cavity 5. The matching arc groove 61 is matched with the extrusion sphere 72. A disassembly cover 42 is arranged on the bottom surface of the joint base 4. The disassembly cover 42 is threadedly connected to the joint base 4. The center of the disassembly cover 42 is docked with one end of the positioning vertical rod 74.

[0028] In this embodiment, when the household water system is operating normally, the device supplies water at the position of the butt joint 3. A large amount of water flows into the vertical pipe cavity 6. The water flow pressure impacts the extrusion sphere 72. The extrusion sphere 72 and the extrusion adjustment column 71 quickly retract along the lifting cavity 7. The horizontal pipe cavity 5 and the vertical pipe cavity 6 quickly form a herringbone channel in the working state to complete the water supply. When the household water system stops, by using the elastic effect of the socket spring 75, the extrusion adjustment column 71 and the extrusion sphere 72 immediately return to their original positions. The extrusion sphere 72 fits with the matching arc groove 61 to close the opening of the vertical pipe cavity 6 channel and prevent the water pump from overflowing.

[0029] When the socket spring 75 reaches the end of its service life, the disassembly cover 42 is disassembled at the bottom of the joint base 4. Since the extension groove 41 is connected to the lifting cavity 7, it is convenient to replace the socket spring 75.
