In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following description of the present invention is provided with reference to the accompanying drawings, which are only some embodiments of the present invention, and it is obvious for a person skilled in the art to obtain other drawings without creative efforts.

As shown in fig. 1 to 4, the drain valve with adjustable discharge speed according to an embodiment of the present invention includes a valve body 10 and a valve core 20 that can be slidably disposed in the valve body 10 to open or close a drain opening 11 of the drain valve, a baffle 30 is disposed at a bottom end of the valve core 20, when the valve core 20 moves upward to open the drain opening 11, a water passage a is formed between the baffle 30 and the drain opening 11, and the baffle 30 can be movably disposed on the valve core 20 to adjust a flow cross-sectional area of the water passage a.

The baffle 30 can be selectively and slidably disposed on the valve element 20 up and down, or the baffle 30 can be selectively and slidably disposed on the valve element 20 in the circumferential direction, and the specific movable connection mode of the baffle 30 is not limited as long as the baffle 30 can adjust the flow cross-sectional area of the water passage a. In this embodiment, the flapper 30 is provided on the valve body 20 so as to be slidable vertically.

In this embodiment, the valve core 20 includes a water sealing disc 21 disposed at the bottom end, a sealing gasket 24 is disposed at the position of the water sealing disc 21, the water sealing disc 21 is in sealing fit with the water outlet 11 through the sealing gasket 24, the baffle 30 is disposed below the water sealing disc 21, the baffle 30 includes a first baffle 31 fixed on the bottom surface of the water sealing disc and a second baffle 32 capable of moving in a vertical direction relative to the first baffle 31, and a water passing channel a is formed between the bottom end edge of the second baffle 32 and the edge of the water outlet 11.

In this embodiment, the second baffle 32 is movably attached to the valve core 20. Concretely, case 20 still includes a cavity valve rod 22 and connecting rod 23, and the bottom of valve rod 22 is located to water sealing disc 21, and connecting rod 23 runs through cavity valve rod 22 and can connect in cavity valve rod 22 with sliding from top to bottom, and the bottom rigid coupling of connecting rod 23 has second baffle 32, and connecting rod 23 upwards stretches out valve body 10 to can adjust from top to bottom connecting rod 23 in the top of valve body 10, need not pull down valve body 10 from the base 12 of drain valve during regulation like this, and it is more convenient to adjust. The baffle 30 is of an annular structure, the first baffle 31 comprises a first annular blocking wall 311 extending longitudinally, the second baffle 32 comprises a second annular blocking wall 321 extending longitudinally, the second annular blocking wall 321 is positioned in the first annular blocking wall 311, and when the connecting rod 23 is moved downwards, the second annular blocking wall 321 is driven to move towards the direction of withdrawing from the first annular blocking wall 311, so that when the valve core 20 opens the water outlet upwards as shown in fig. 3, the distance L between the bottom end edge of the second baffle 32 and the edge of the water outlet 11 is reduced, and the through-flow sectional area of the water passage a is reduced; when the connecting rod 23 is moved upward, the second annular blocking wall 321 is moved to retract into the first annular blocking wall 311, so that when the valve core 20 opens the water outlet upward, as shown in fig. 4, the distance L between the bottom edge of the second blocking plate 32 and the edge of the water outlet 11 is increased, thereby increasing the flow cross-sectional area of the water passage a. Preferably, the diameter of the baffle 30 is smaller than the diameter of the drain opening 11, and the baffle 30 is positioned in the drain opening 11 when the valve body 20 closes the drain opening.

In the embodiment, the baffle 30 is provided with the baffle wall extending longitudinally, the baffle wall extends circumferentially to form the annular baffle wall, and the distance between the bottom end of the baffle 30 and the bottom end of the valve core 20 in the longitudinal direction is adjustable to realize that the through-flow sectional area of the water passing channel A is adjustable.

In this embodiment, the top end and the bottom end of the hollow valve stem 22 penetrate through an overflow pipe forming the drain valve, and when the water in the water tank exceeds the overflow water level, the water can overflow from the hollow valve stem 22 to the drain port 11, thereby preventing the water in the water tank from overflowing to the outside.

The utility model discloses a theory of operation is:

as shown in fig. 1 and 3, when the connecting rod 23 is moved downward, the connecting rod 23 drives the second annular blocking wall 321 to move in a direction of withdrawing from the first annular blocking wall 311, so that when the valve core 20 opens the drain opening 11 of the drain valve, since the distance L between the bottom end of the second annular blocking wall 321 and the edge of the drain opening 11 is reduced, that is, the through-flow sectional area of the water passage a is reduced, the discharge speed of the drain valve is reduced.

As shown in fig. 1 and 4, when the connecting rod 23 is moved upward, the connecting rod 23 drives the second annular blocking wall 321 to move in the direction of retracting into the first annular blocking wall 311, so that when the valve core 20 opens the drain opening 11 of the drain valve, the distance L between the bottom end of the second annular blocking wall 321 and the edge of the drain opening 11 is increased, that is, the through-flow sectional area of the water passage a is increased, so that the discharge speed of the drain valve is increased.

Therefore, the position of the connecting rod 23 is adjusted as required to adjust the distance L between the bottom end of the second annular blocking wall 321 and the edge of the water outlet 11, so as to adjust the cross-sectional area of the water passage a.

Alternatively, if the convenience of adjusting the flow cross-sectional area of the flow passage a above the valve body 10 is not taken into consideration, the second baffle 32 may be directly and movably attached to the first baffle 31, for example, a slide groove (not shown) may be provided on the inner wall or the outer wall of the first baffle 31, the second baffle 32 may be slidably mounted in the slide groove up and down, and the distance between the bottom end of the second baffle 32 and the edge of the water discharge opening 11 may be adjusted by adjusting the relative position of the second baffle 32 and the first baffle 31, and at this time, the valve body 10 needs to be detached from the base 12 by adjusting the second baffle 32.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
