Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a connector that can stably control the outlet water pressure. Background Technology
[0002] In home environments, connectors that can stably control water pressure are used to ensure consistent water pressure in showers, kitchen faucets, and other appliances, improving the user experience. Especially in high-rise buildings, where water pressure varies with floor height, these connectors ensure a stable water flow for all residents. In agriculture, precise water pressure control is crucial for irrigation efficiency at the connection point. By using connectors that can stably control water pressure, even water supply to sprinkler or drip irrigation systems can be ensured, improving water resource utilization efficiency and contributing to healthy crop growth.
[0003] Fittings that can stably control outlet water pressure are used in a variety of scenarios, especially in places where high pressure stability of water flow is required. Traditional fittings typically use components such as mechanical pressure reducing valves, spring-loaded diaphragms, or pistons to sense and adjust outlet pressure. These devices rely on manual setting or complex feedback mechanisms (such as electronic sensors) to maintain stable pressure output, which is costly and complex to maintain. Therefore, fittings that can stably control outlet water pressure are proposed. Utility Model Content
[0004] The main purpose of this invention is to provide a connector that can stably control the outlet water pressure, solving the problem that traditional connectors usually use mechanical pressure reducing valves, spring-loaded diaphragms or pistons to sense and adjust the outlet pressure. These devices rely on manual settings or complex feedback mechanisms (such as electronic sensors) to maintain stable pressure output, which is costly and complicated to maintain.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A connector capable of stably controlling the outlet water pressure includes a pressure regulator body. A TPR short piece is fixedly snapped into the inside of the pressure regulator body. A limit ring is fixedly connected inside the pressure regulator body. One side of the limit ring abuts against the TPR short piece. A spring is fixedly connected to one side of the limit ring. A transmission sleeve is fixedly connected to one end of the spring. A TRP long piece is fixedly sleeved inside the transmission sleeve. One inner end of the TRP long piece is movably sleeved inside the TPR short piece.
[0007] Furthermore, a cover is fixedly connected to the lower part of the voltage regulator body, a connection hole is provided in the middle of the cover, and a first threaded groove is provided on the outer side of the voltage regulator body.
[0008] Furthermore, a connecting sleeve is fixedly connected to one end of the voltage regulator body, and a second threaded groove is provided on the inner side of the connecting sleeve.
[0009] Furthermore, a threaded connector is threaded to the inner side of the second threaded groove, a gasket is abutted against the inner side of the threaded connector, and the gasket is snapped into the connecting sleeve. A male connector is fixedly connected to the top of the threaded connector.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] This invention, through the design of the TRP long component, reduces connector costs, simplifies the structure, and facilitates maintenance. When the water pressure increases, the water flow propels the TRP long component, bringing it closer to the TPR short component. This reduces the gap between the TRP long component and the inner wall of the spring, decreasing the water flow rate and consequently reducing the pressure of the water discharged from the TPR short component. Simultaneously, the TRP long component compresses the spring via a transmission sleeve. According to fluid mechanics principles, when liquid flow is locally constricted, the flow velocity increases, but the overall flow rate is limited, resulting in a decrease in downstream pressure. This design reduces connector costs and simplifies maintenance.
[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] like Figures 1-6 As shown, the connector that can stably control the outlet water pressure includes a pressure regulator body 1. A TPR short piece 13 is fixedly snapped into the inside of the pressure regulator body 1. A limit ring 15 is fixedly connected inside the pressure regulator body 1. One side of the limit ring 15 abuts against the TPR short piece 13. A spring 16 is fixedly connected to one side of the limit ring 15. A transmission sleeve 5 is fixedly connected to one end of the spring 16. A TRP long piece 4 is fixedly sleeved inside the transmission sleeve 5. One inner end of the TRP long piece 4 is movably sleeved in the TPR short piece 13. By adopting the above technical solution, the upper end of the TRP long piece 4 is movably sleeved in the TPR short piece 13. The position of the TRP long piece 4 is designed, and the elastic coefficient of the spring 16 is set so that during the movement of the TRP long piece 4, the upper end of the TRP long piece 4 can always be sleeved in the TPR short piece 13, and the upper end of the TRP long piece 4 remains sleeved in the limit ring 15.
[0022] The TPR short piece 13 is hollow inside, and a baffle is installed in the middle of the top of the TPR short piece 13. Water can only be discharged from the top side of the TPR short piece 13. When the TRP long piece 4 is inserted into the TPR short piece 13, the water flows from the TRP long piece 4 through the gap between the inner walls of the TRP long piece 4 and the TPR short piece 13 into the TPR short piece 13. When the distance between the TRP long piece 4 and the TPR short piece 13 gets closer, the gap between the inner walls of the TRP long piece 4 and the TPR short piece 13 will become smaller, so that the water flow rate through the gap between the inner walls of the TRP long piece 4 and the TPR short piece 13 will decrease.
[0023] The TRP long piece 4 has a certain curvature inside, which allows the water flow to better transmit force to the TRP long piece 4 and push the TRP long piece 4.
[0024] A cover 6 is fixedly connected to the bottom of the voltage regulator body 1. A connection hole 7 is opened in the middle of the cover 6. A first threaded groove 3 is opened on the outer side of the voltage regulator body 1. By adopting the above technical solution, the position of the connection hole 7 is aligned with the TRP long piece 4, so that the external water flow can only enter the TRP long piece 4 through the connection hole 7, and the water flow can better concentrate and transmit the force to the TRP long piece 4.
[0025] The first threaded groove 3 can be threaded to connect to external pipelines;
[0026] The cover 6 can limit the TRP long piece 4 and prevent the TRP long piece 4 from detaching from the voltage regulator body 1 during movement.
[0027] One end of the voltage regulator body 1 is fixedly connected to a connecting sleeve 8. A second threaded groove 9 is provided on the inner side of the connecting sleeve 8. By adopting the above technical solution, the second threaded groove 9 can be used to thread the pipeline.
[0028] The inner side of the second threaded groove 9 is threadedly connected to a threaded connector 11, and the inner side of the threaded connector 11 abuts against a gasket 12, and the gasket 12 is snapped into the connecting sleeve 8. A male connector 10 is fixedly connected above the threaded connector 11. By adopting the above technical solution, the connection between the gasket 12 and the connecting sleeve 8 can be sealed by the gasket 12.
[0029] The external part of the male connector 10 can be connected to the connector head.
[0030] It should be noted that in actual use, the water flows into the main body 1 of the voltage regulator through the connection hole 7 via the external thread of the first threaded groove 3, and then into the TRP long part 4. The water flows through the TRP long part 4 into the TPR short part 13, and then from the TPR short part 13 into the main body 1 of the voltage regulator and is discharged from the male connector 10.
[0031] When the water pressure increases, the water flow can push the TRP long piece 4 to move, and the distance between the TRP long piece 4 and the TPR short piece 13 will be closer, which will make the gap between the TRP long piece 4 and the inner wall of the spring 16 smaller, thus reducing the water flow rate and consequently reducing the water pressure discharged from the TPR short piece 13. At the same time, the TRP long piece 4 drives the spring 16 to compress through the transmission sleeve 5.
[0032] This invention provides a connector that can stably control the outlet water pressure, solving the problem that traditional connectors typically use mechanical pressure reducing valves, spring-loaded diaphragms, or pistons to sense and adjust the outlet pressure. These devices rely on manual settings or complex feedback mechanisms such as electronic sensors to maintain stable pressure output, resulting in high costs and complex maintenance. This invention is more practical.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
