Description

Technical Field

[0001] This utility model relates to the field of water stop valve technology, specifically to a water stop valve that can be easily opened and closed. Background Technology

[0002] In traditional ball valve designs, the sealing structure primarily relies on two sealing rings above and below the ball core to achieve a sealing function. Specifically, the ball core has through-holes that align or misalign with the flow path of the valve body as the ball core rotates, thus enabling the valve to open and close. However, this design has some significant drawbacks. Due to the structural limitations between the ball core and the sealing rings, the sealing performance is often unsatisfactory. Especially under operating conditions with large temperature variations, the materials of the ball core and sealing rings will change in size due to thermal expansion and contraction. This can lead to changes in the fit clearance between the sealing ring and the ball core. When the sealing ring expands due to heat, it will make it difficult for the ball core to rotate, resulting in a tight feel for the user when opening and closing the valve. When the sealing ring contracts due to cold, leakage may occur. These problems not only affect the performance of the ball valve but may also shorten its service life and increase maintenance and replacement costs. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Reference Figures 1 to 6 As shown, a water-stop valve that can be easily switched on and off includes a valve body 1. The valve body 1 has an inlet channel 11, an installation chamber 12, and an outlet channel 13 connected in sequence. It also includes a sealing gasket 2 fixed to the bottom of the installation chamber 12. The sealing gasket 2 has a plurality of water passage holes 21 communicating with the inlet channel 11. It also includes a valve core 3 inserted into the installation chamber 12. The lower end of the valve core 3 abuts against the sealing gasket 2. The lower end face of the valve core 3 has a blocking part 31 and a flow guiding part 32. By rotating the valve core 3, the blocking part 31 can be used to close the water passage holes 21, or the flow guiding part 32 can be used to align with the water passage holes 21. It also includes a locking cover 4 threadedly connected to the installation chamber 12. The locking cover 4 seals against the valve core 3.

[0024] In use, by rotating the valve core 3, when the sealing part 31 of the valve core 3 is aligned with the water passage hole 21, the stop valve is in the closed state; when the flow guiding part 32 of the valve core 3 is aligned with the water passage hole 21, the stop valve is in the open state.

[0025] The number of water passage holes 21 includes, but is not limited to, two, and they are arranged symmetrically. The flow guide 32 is formed by the upward indentation of the lower end of the valve core 3.

[0026] This utility model uses a structure where the valve core 3 presses down on the sealing gasket 2, and the contact area between the valve core 3 and the sealing gasket 2 is large. Compared with the ball valve in the prior art, it can avoid the problem that the sealing gasket 2 shrinks due to cold water, thus affecting the sealing effect, or that the sealing gasket 2 expands due to hot water, resulting in a tight feel when opening and closing.

[0027] Reference Figure 2 and Figure 3 As shown, a first sealing ring 5 is sandwiched between the locking cover 4 and the valve body 1, and a second sealing ring 6 is sandwiched between the locking cover 4 and the valve core 3, thereby preventing water from seeping out of the valve body 1 and allowing water to enter the installation chamber 12 through the water passage 21 and then enter the water outlet channel 13.

[0028] The locking cover 4 has an external thread on its lower outer circumferential surface and an internal thread on its inner circumferential surface. The upper end of the locking cover 4 has a pressing part 41 that presses against the first sealing ring 5, and the lower end of the locking cover 4 has an inclined surface 42 that presses against the second sealing ring 6. By locking the locking cover 4 into the valve body 1 to a certain depth, the degree of pressing between it and the first sealing ring 5 and the second sealing ring 6 can be adjusted to ensure the sealing effect.

[0029] Reference Figure 5 and Figure 6 As shown, the valve core 3 is provided with a guide portion 33 extending laterally, and the lower end face of the guide portion 33 is provided with a guide groove 331. The mounting chamber 12 is provided with a guide ring 121 embedded in the guide groove 331. Through the cooperation of the guide groove 331 and the guide ring 121, the rotation path of the valve core 3 when rotating the switch can be restricted, preventing the valve core 3 from deviating and avoiding the sealing portion 31 from failing to properly align with the water passage hole 21.

[0030] Reference Figure 5 and Figure 6 As shown, the valve body 1 is provided with two limiting strips 122 connecting its outer wall and the guide ring 121. The two end faces of the guide part 33 can rotate between the positions of respectively abutting the two limiting strips 122. By rotating the guide part 33 to abut the two limiting strips 122 respectively, it can serve as feedback and position restriction for the valve core 3 to rotate to the position of opening or closing the water passage 21. The user can clearly feel that the valve core 3 has reached the predetermined position, thereby providing clear operation feedback and enhancing the reliability of operation and user experience.

[0031] It also includes a handle 7 and a screw 8 for connecting the handle 7 and the valve core 3. The fixed connection between the handle 7 and the valve core 3 makes it easy for the user to operate the valve core 3 to rotate through the handle 7, and the screw 8 makes it easy to assemble the handle 7 and the valve core 3.

[0032] It also includes a decorative cover 9 that snaps into the handle 7. The decorative cover 9 is used to cover the blind hole of the screw 8 in the handle 7. The decorative cover 9 may be printed with a corresponding trademark or pattern, or a card may be sandwiched between the decorative cover 9 and the handle 7. The card may be printed with a corresponding trademark or pattern to facilitate brand recognition and product beautification.

[0033] The lower end of the handle 7 is provided with a circular ring 71, and the locking cover 4 is provided with a circular groove 43 for the circular ring 71 to be inserted. By cooperating with the circular ring 71 and the circular groove 43, the rotation path of the handle 7 can be restricted to prevent the handle 7 from deviating.

[0034] The installation chamber 12 is provided with two positioning posts 123. The positioning posts 123 are embedded in the sealing gasket 2, thereby preventing the valve core 3 from rotating and causing the sealing gasket 2 to rotate. The positioning posts 123 facilitate the installation of the sealing gasket 2.

[0035] During assembly, first insert the sealing gasket 2 into the mounting chamber 12, then insert the valve core 3 into the mounting chamber 12, and fit the first sealing ring 5 and the second sealing ring 6. Then screw in the locking cover 4, and then assemble the handle 7 with the valve core 3 using the screw 8. Finally, fasten the decorative cover 9 onto the handle 7.
