Description

Technical Field

[0001] This utility model belongs to the field of pipeline connection, specifically relating to a sealing and positioning component for water pipe valve connections. Background Technology

[0002] Angle valves are common control valves in water supply and heating systems. They are mainly used to regulate water flow, control water pressure, and connect pipes. The valve body is designed at a 90-degree right angle and includes an inlet pipe, an outlet pipe, and a knob. The inlet pipe consists of a threaded section and a smooth section. The threaded section has an indented thread, and the highest point of the thread is flush with the surface of the smooth section. The inlet pipe is connected to the female connector of the water supply pipe. The presence and flow rate of water in the outlet pipe are controlled by rotating the knob.

[0003] The existing angle valve inlet pipe does not have a seal. When it is installed with the water supply pipe, Teflon tape is usually wrapped around it to ensure a seal. This installation is time-consuming and troublesome. In addition, since each household has different water supply locations, the direction of the angle valve outlet is inconsistent. After adjustment, it is easy to leak water, and repeated adjustments are difficult.

[0004] To address the aforementioned issues, patent document CN220102128U discloses an angle-adjustable angle valve. It reveals a rotatable, sealed connection between the valve body and the inlet body, ensuring that when the inlet body is perpendicular to the wall, the outlet direction can always be adjusted by rotating the valve body to the desired angle. However, this solution has several drawbacks in practical use: 1. The inlet body is directly connected to a threaded connection pre-installed in the wall without a seal; 2. This angle valve represents a significant improvement over existing angle valves, requiring replacement of the original valve during use, resulting in higher costs. Utility Model Content

[0005] The purpose of this invention is to overcome the existing problems of angle valve connection angle and sealing, and to provide a water pipe valve sealing and positioning component that plays a sealing and positioning role when connecting angle valves.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a water pipe valve sealing and positioning component, including a pipe sleeve, a sealing ring I and a sealing ring II. The inner wall of the pipe sleeve has a threaded area and a smooth area from left to right. The threaded area is provided with a protruding positioning thread, and the smooth area is provided with a positioning groove I. The sealing ring I is positioned in the smooth area through the positioning groove I. The left end face of the pipe sleeve is provided with a positioning groove II. The sealing ring II is positioned in the left end face of the pipe sleeve through the positioning groove II. The positioning thread of the pipe sleeve matches the thread of the angle valve inlet pipe thread section. When the left end face of the pipe sleeve is in tight contact and sealed with the end face of the water supply pipe through the sealing ring II, the sealing ring I is in contact and sealed with the smooth section of the angle valve inlet pipe.

[0007] Optionally, the surface of the sleeve is provided with an anti-slip portion.

[0008] The usage and principle of this utility model: The right end of the sleeve is installed with the smooth area facing the angle valve inlet pipe. The sleeve is rotated clockwise until it reaches the bottom, exposing the threaded section of the angle valve inlet pipe. The threaded section of the angle valve inlet pipe is connected to the female connector of the water supply pipe. The angle valve is rotated clockwise until it reaches the bottom. Then, the angle valve outlet is rotated and adjusted to the required orientation. The angle valve is then squeezed and the sleeve is rotated clockwise until the left end face of the sleeve is in close contact with the end face of the female connector of the water supply pipe. The orientation of the angle valve outlet is fixed. One end face of the sleeve is sealed to the end face of the female connector of the water supply pipe by sealing ring II. At this time, the other end of the sleeve, sealing ring I, is in close contact with the smooth section of the angle valve inlet pipe in the smooth area inside the sleeve and is sealed by sealing ring I. This sealing and positioning component has a simple structure and does not require modification of existing angle valves. The sealing and positioning of the angle valve and the female connector of the water supply pipe are achieved through the threaded sleeve, sealing ring I, and sealing ring II.

[0009] Compared with the prior art, the present invention has at least the following beneficial effects: The present invention has a simple structure, does not require modification of the existing angle valve, and can provide a better seal and 360-degree repeated arbitrary positioning for the connection between the angle valve and the water supply pipe female head.

[0011] The following are the detailed markings in the attached drawings: sleeve 1, sealing ring I 2, sealing ring II 3, positioning thread 4, anti-slip part 5. Detailed Implementation

[0012] Example 1, in conjunction with the following Figure 1 To further illustrate this utility model, the water pipe sealing and positioning component includes a pipe sleeve 1, a sealing ring I 2, and a sealing ring II 3. The inner wall of the pipe sleeve has a threaded area and a smooth area from left to right. The threaded area has a protruding positioning thread 4, and the smooth area has a positioning groove I. The sealing ring I is positioned in the smooth area through the positioning groove I. The sealing ring I and the positioning groove I can be reinforced and fixed by embedding, glue, or other means. The left end face of the pipe sleeve has a positioning groove II, and the sealing ring II is positioned in the left end face of the pipe sleeve through the positioning groove II. The sealing ring II and the positioning groove II can be reinforced and fixed by embedding, glue, or other means. The cross-sections of the sealing ring I and the sealing ring II can be circular, semi-circular, square, triangular, or other shapes that are conducive to sealing. The positioning thread of the pipe sleeve matches the thread of the angle valve inlet pipe. When the left end face of the pipe sleeve is in close contact and sealed with the end face of the water supply pipe through the sealing ring II, the sealing ring I is in contact and sealed with the smooth section of the angle valve inlet pipe.

[0013] To facilitate the rotation of the sleeve, an anti-slip part 5 is provided on the surface of the sleeve. The anti-slip part can be roughened or have an uneven surface.

[0014] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
