Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to angle valves. Background Art

[0002] In daily life, an angle valve is a commonly used waterway control component, which is widely used in household pipeline systems. The flow of water source is controlled by opening and closing the angle valve. The valve body of the angle valve has three ports: a water inlet, a water volume control port, and a water outlet.

Detailed implementation manners

[0028] The following further describes the present utility model in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures.

[0029] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components.

[0030] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0031] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] As Figures 1 - 3 shown, this embodiment provides an angle valve. The angle valve includes a tee-shaped housing. The tee-shaped housing includes a water inlet pipe 110, a water outlet pipe 120, and a valve core pipe 130 that are interconnected. The water inlet pipe 110 and the valve core pipe 130 are located on the same straight line, and the water outlet pipe 120 is located beside the valve core pipe 130. A retaining ring 140 is provided at the connection between the valve core pipe 130 and the water inlet pipe 110. The retaining ring 140 is provided with a through hole 141. An annular protrusion 142 is provided along the circumference of the through hole 141 on the side of the retaining ring 140 facing the valve core pipe 130. The cross-sectional shape of the annular protrusion 142 is arc-shaped, so that when the annular protrusion 142 contacts the valve core, a linear contact is formed, providing a more reliable sealing effect. At the same time, the contact area between the valve core and the annular protrusion 142 is reduced, the adsorption force of the valve core is lowered, effectively avoiding the situation that the valve core is adsorbed in the valve body in the long-term closed state, and improving the opening flexibility of the angle valve.

[0033] Optionally, as Figure 2 shown, the water inlet pipe 110 further includes a connection section 111, a transition section 112, and a threaded section 113. One end of the connection section 111 is connected to the valve core pipe 130, and the other end is connected to the transition section 112. The end of the transition section 112 away from the connection section 111 is connected to the threaded section 113, and an external thread is provided on the threaded section 113. In this embodiment, the water inlet pipe 110 is integrally integrated on the tee-shaped housing. Through the external thread on the threaded section 113 of the water inlet pipe 110, the tee-shaped housing can be threadedly connected to an external pipeline, reducing the use of adapters, reducing the leakage risk, improving the reliability of the pipeline connection, and further saving costs by reducing the number of adapters.

[0034] It should be noted that the length of the connection section 111 in this embodiment can be adaptively adjusted according to actual usage requirements to meet the requirements under different installation conditions.

[0035] Optionally, as Figure 2 shown, the wall thickness of the transition section 112 is greater than the wall thickness of the connection section 111, so that an annular step is formed at the connection between the inner walls of the transition section 112 and the connection section 111. This design can enhance the structural strength of the transition section 112, making the water inlet pipe 110 not easily deformed, and ensuring the reliability and stability of the connection between the water inlet pipe 110 and the external pipeline.

[0036] Optionally, as Figure 2 shown, the angle valve further includes a valve core assembly 150. The valve core assembly 150 is disposed within the valve core tube 130. The valve core assembly 150 is used to open or close the through hole 141, thereby controlling the opening or closing of the water flow, ensuring that the flow rate and pressure of the water flow can be adjusted as needed, and improving the flexibility and convenience of use.

[0037] Optionally, the valve core assembly 150 includes an adjusting rod 151 and a sealing plug 152. The adjusting rod 151 is threadedly connected to the inner wall of the valve core tube 130. The sealing plug 152 is disposed at one end of the adjusting rod 151 facing the retaining ring 140. By rotating the adjusting rod 151, the moving position of the sealing plug 152 can be precisely controlled, so that the sealing plug 152 can accurately abut or separate from the annular protrusion 142, realizing precise adjustment of the water flow.

[0038] Specifically, the inner wall of the valve core tube 130 is provided with internal threads, and the part of the adjusting rod 151 in contact with the inner wall of the valve core tube 130 is provided with external threads. The internal threads and the external threads are screwed together. The threaded connection design makes it easier for users to operate the valve. Without complex tools or steps, the user only needs to rotate the adjusting rod 151 to complete the opening and closing adjustment of the water flow.

[0039] Optionally, as Figure 2 and Figure 3 shown, an installation groove 1511 is provided inside the adjusting rod 151. The sealing plug 152 includes an installation portion 1521 and a sealing portion 1522. The installation portion 1521 is inserted into the installation groove 1511. When the sealing portion 1522 abuts against the annular protrusion 142, a reliable linear seal is formed, which can effectively prevent water leakage. The installation portion 1521 of the sealing plug 152 is inserted into the installation groove 1511 of the adjusting rod 151, ensuring the stability of the sealing plug 152 on the adjusting rod 151 and avoiding loosening or falling off of the sealing plug 152 due to operation or water flow impact; moreover, this design simplifies the installation and replacement process of the sealing plug 152, reducing the maintenance time and maintenance difficulty.

[0040] In this embodiment, the sealing plug 152 is a rubber sealing plug 152. And in order to ensure the firm connection between the rubber sealing plug 152 and the adjusting rod 151, the installation portion 1521 of the rubber sealing plug 152 is press-fitted into the installation groove 1511 of the adjusting rod 151.

[0041] Optionally, an arc-shaped abutting surface 15221 is provided at one end of the sealing portion 1522 away from the adjusting rod 151. The design of the arc-shaped abutting surface 15221 can ensure that when the sealing portion 1522 abuts against the annular protrusion 142, a linear seal is formed inside the annular protrusion 142. Especially in a high-pressure environment, the sealing effect is more reliable.

[0042] Optionally, asFigure 3 As shown, the valve core assembly 150 further includes a first gasket 153. The first gasket 153 includes a flat gasket plate 1531 and an annular vertical plate 1532. The flat gasket plate 1531 and the annular vertical plate 1532 enclose a limiting space. The installation portion 1521 penetrates through the flat gasket plate 1531 and is inserted into the installation groove 1511. At least a part of the sealing portion 1522 is limited in the limiting space. Since the sealing portion 1522 is effectively supported and fixed in the limiting space, the contact between the sealing portion 1522 and the annular protrusion 142 is more stable, thereby enhancing the sealing effect. By providing the first gasket 153, even when the sealing portion 1522 bears a large pressure, the sealing performance can still be guaranteed, reducing the leakage risk.

[0043] Optionally, as Figure 2 shown, the valve core assembly 150 further includes a cap 154 and a sealing sheet 155. The cap 154 is covered on the end of the valve core tube 130 away from the water inlet pipe 110. The cap 154 is provided with an avoidance hole. The adjusting rod 151 penetrates through the avoidance hole. The sealing sheet 155 is sleeved on the adjusting rod 151 and is limited between the cap 154 and the valve core tube 130, which can seal the end of the valve core tube 130, further preventing the angle valve from leaking. And when it is necessary to perform maintenance or replace the sealing sheet 155, only the cap 154 needs to be simply disassembled, without disassembling the entire valve assembly, improving the efficiency of the maintenance work.

[0044] Optionally, a limiting platform is provided at the end of the valve core tube 130, and a second gasket 156 is provided on the limiting platform. One end of the sealing sheet 155 abuts against the second gasket 156, and the other end abuts against the cap 154. The limiting platform provides a stable fixing position for the sealing sheet 155, avoiding the displacement or deformation of the second gasket 156, and can improve the sealing effect. In this embodiment, the sealing sheet 155 is a rubber sealing sheet, and the rubber sealing sheet has good elasticity and flexibility, ensuring the effectiveness of the seal and reducing the leakage risk.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
