Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1: the drain valve adopts a barrel type drain valve

Referring to fig. 1 to 4, a drainage device for increasing a drainage speed according to a first preferred embodiment of the present invention includes a water tank 1 and a drainage valve 2 disposed in the water tank 1. The drain valve 2 comprises a valve body 10, a drain port 11 arranged on the valve body 10 and a sealing member 20 movably arranged on the valve body 10. The sealing member 20 is provided with a sealing portion 21 which is in sealing engagement with or disengaged from the drain opening 11. When the sealing portion 21 is positioned to open the drain port 11, a water inlet 14 is formed between the sealing portion 21 and the drain port 11 to communicate the cavity of the tank 1 with the drain port 11. When the sealing member 20 is driven to move upward, the sealing portion 21 moves upward to open the drain port 11 for draining, and after the draining is finished, the sealing member 20 falls down, so that the sealing portion 21 reseals the drain port 11 to stop the draining.

The drainage device further comprises a cover 3, the cover 3 is installed outside the drainage valve 2 and can cover the water inlet 14, a water passage a for communicating the inner cavity of the water tank 1 with the water inlet 14 is arranged between the cover 3 and the bottom wall of the water tank 1, or the cover 3 can be directly provided with the water passage a for communicating the inner cavity of the water tank 1 with the water inlet 14, and the former is specifically adopted in the embodiment. When the sealing portion 21 opens the drain port 11, the water in the inner cavity of the water tank 1 flows to the drain port 11 through the water passage a and the water inlet 14 in sequence, and the inlet of the water passage a is positioned lower than the highest position of the water inlet 14. By providing the cover 3, a large amount of air is sucked into the drain port 11 when the drain valve 2 is prevented from draining by the cover 3, so that the influence of the mixing of a large amount of air can be avoided, the drain speed of the drain valve can be increased, and the drain noise can be reduced. In addition, since the inlet position of the water passage a is lower than the highest position of the water inlet 14, when the water level of the water tank 1 falls to the highest position of the water inlet 14 during the water discharge, a large amount of air is not sucked into the water outlet 11 through the water inlet 14 to break the siphon formed during the water discharge, and the siphon time formed during the water discharge can be prolonged, thereby further improving the discharge speed. Further preferably, the inlet position of the water passage a is lower than the residual water level of the drain valve 2, so that the air is prevented from being sucked into the water inlet 14 and the water outlet 11 through the inlet of the water passage a as much as possible during the drainage process.

In the drainage device of the present embodiment, the cover 3 has a hollow inner cavity communicated with the drainage port 11, the inner cavity of the cover 3 forms a water passage a, the bottom end of the cover 3 forms an opening communicated with the inner cavity, and a gap between the edge of the opening of the cover 3 and the bottom wall of the water tank 1 forms an inlet of the water passage a. In other embodiments, the lower portion of the side wall of the cover 3 may be provided with an inlet of the water passage a.

Referring to fig. 1, 2 and 3, in the drainage device of the present embodiment, the valve body 10 is a barrel-shaped structure, the valve body 10 includes a main body 12 and a base 13, the main body 12 and the base 13 are detachably connected, and the detachable connection structure of the two is implemented by using the prior art. The base 13 is formed with a water outlet 11, the sealing member 20 is movably arranged in the main body 12, the top end of the cover 3 is provided with a circular through hole 301 for the valve body 10 to penetrate through, the valve body 10 of the drain valve 2 is matched with the through hole 301 in size so as to seal the top end of the cover 3, and air is prevented from being sucked into the water outlet 11 from the top end of the cover 3. Preferably, the outer wall of the valve body 10 and the inner wall of the through hole 301 are sealed by a sealing member, but a small amount of clearance may be provided between the two, but the effect is slightly inferior to the former. The cover 3 surrounds the base 13 and is fixedly connected to the base 13, specifically, in this embodiment, the cover 3 is fixedly connected to the base 13 by interference fit, and of course, the two may also be fixed by clamping or screwing.

In the drainage device of the present embodiment, the flow area of the water passage a is greater than or equal to the flow area of the drainage port 11, so that the displacement of the drainage valve 2 can be effectively ensured.

Preferably, the top end of the cover 3 is positioned higher than the highest position of the water inlet 14, so that the water inlet 14 can be effectively covered and the flow cross-section of the water passage a can be made as large as possible.

The cover 3 may be formed separately from or integrally with the valve body 10, preferably, the cover 3 is attached to the valve body 10 and surrounds the outside of the valve body 10. Specifically, in the drain device of the present embodiment, the cover 3 is detachably attached to the base 13 of the valve body 10. Of course, the cover 3 can alternatively be fixedly connected to the water tank 1.

As shown in fig. 1, in the drain device of the present embodiment, the packing 20 includes a stem 22 and a packing plate attached to a bottom end of the stem, the packing plate forming a packing portion 21.

In other embodiments, the sealing member 20 of the barrel-type drain valve 2 can be other structures commonly used in the art, for example, the sealing member 20 is a hollow barrel body, the barrel body is slidably sleeved outside the valve body 10 up and down, and the bottom end edge of the barrel body forms the sealing portion 21.

Example 2: the drain valve adopts flap type

As shown in fig. 5 to 8, the present invention can also be applied to other forms of drain valve structures, such as being also applied to the flap-type drain valve 2, at this time, the sealing member 20 is the flap, the whole flap-type drain valve 2 can be selectively installed in the cover 3, only the through hole 302 for the stay cord 23 to pass is formed on the top wall of the cover 3, and the flap is linked to the stay cord 23 to open or close the drain port 11.

At this time, as shown in fig. 5, the sealing member 20 (flap) is put on the drain port 11 to close the drain port 11, and the tank 1 is not drained. As shown in fig. 6, when the pulling rope 23 is driven upward, the pulling rope 23 drives the sealing member 20 to move upward and open the water discharge opening 11, so that the water tank 1 starts to discharge water, and the water in the inner cavity of the water tank 1 is discharged through the water passage a, the water inlet 14 formed between the sealing member 20 and the water discharge opening 11, and the water discharge opening 11.

Compared with the first embodiment, the top wall of the cover 3 of the present embodiment is not provided with the through hole 301 for the valve body 10 to pass through, and the cover 3 is directly fixed on the bottom wall of the water tank 1. The rest of the structure and principle not described in this embodiment are the same as those of the above embodiment, and are not described again here.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: it is to be understood that modifications may be made to the above-described arrangements in the embodiments or equivalents may be substituted for some of the features of the embodiments, but such modifications or substitutions do not depart from the spirit and scope of the present invention.
