[0003] The liquid distributor with the above structure has the following defects when in use:

[0004] Because the second plate is not provided with liquid leakage hole, a certain amount of liquid in the middle space between the first plate and the second plate cannot be discharged, which not only causes waste, but also causes the liquid accumulated for a long time to corrode the distributor, thereby shortening the service life of the distributor. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a distributor for tower, which is provided with liquid leakage hole on the second plate, the liquid leakage hole is in a normally closed state when the distributor works, and the liquid leakage hole is opened after work to discharge the liquid in the middle space.

[0006] The utility model is realized through the following technical solutions:

[0007] A distributor for a tower equipment includes a first plate and a second plate with a middle space between them. The first plate has several first through holes, and several first and second guide pipes are provided between the first and second plates. The characteristic feature is that at least one of the first through holes has a leakage hole on the second plate below it. A sealing device is provided between the corresponding first through hole and the leakage hole. The sealing device, from top to bottom, includes an upper baffle, a connecting rod, and a lower baffle. The upper baffle is located above the first through hole, and its bottom center is connected to the connecting rod. The connecting rod passes through the first through hole and the leakage hole, and its lower end is connected to the upper center of the lower baffle below the second plate. The upper surface of the lower baffle also has a sealing gasket. The distance between the upper and lower baffles is greater than the distance between the first and second plates. The diameter of the connecting rod is smaller than the diameter of the first through hole and the leakage hole, and the diameter of the first through hole is larger than the diameter of the leakage hole.

[0008] The principle of this utility model is as follows:

[0009] After the liquid fills the middle space of the first and second plates, it enters the upper space above the first plate through several first through holes. As the liquid is continuously injected into the middle space, a certain positive pressure is formed in the middle space. The pressure of the liquid will push the upper baffle to rise. After the upper baffle rises, it will drive the connecting rod and the lower baffle to rise. The sealing gasket will block the leakage hole. When the liquid filling of the tower is completed, the positive pressure in the middle space will disappear. Under the action of its own gravity, the upper baffle, connecting rod and lower baffle will fall back to the initial position. The liquid in the middle space will flow out through the gap between the connecting rod and the leakage hole.

[0010] This utility model distributor is an improvement on the utility model patent with publication number CN215353470U entitled "A Disc-type Liquid Distributor". The only difference is that a leakage hole is provided on the second plate below at least one first through hole, and a sealing device is provided between the first through hole and the leakage hole. Other structures will not be described in detail here.

[0011] The upper and lower baffles of this utility model are preferably circular sheet structures.

[0012] The diameter of the first through hole of this invention is larger than the diameter of the leakage hole, that is, the water flow rate at the first through hole is significantly greater than the water flow rate at the leakage hole, ensuring that when the water flows out, the upper baffle is subjected to greater force, causing the entire sealing device to rise upward.

[0013] Furthermore, the present invention has one leakage hole, the upper surface of the second plate is a conical surface, and the leakage hole is located at the bottom.

[0014] The upper surface of the second plate of this utility model adopts a conical design, and the leakage hole is located at the bottom end to ensure that no liquid accumulates in the second space.

[0015] Furthermore, in this invention, upper guide posts are evenly distributed around the first through hole at the upper baffle, and the upper guide posts pass through the edge of the upper baffle.

[0016] Furthermore, the lower end face of the second plate at the leakage hole of this utility model is provided with lower guide posts evenly distributed around the circumference, and the lower guide posts pass through the edge of the lower baffle.

[0017] Guide posts are installed at the upper and lower baffles to ensure that the upper and lower baffles can only move straight up and down.

[0018] To ensure a good seal between the sealing gasket and the leakage hole, this utility model adopts the following two technical solutions:

[0019] 1) Furthermore, the cross-section of the leakage hole of this utility model is a frustum-shaped cone with a smaller top and a larger bottom, and the cross-section of the sealing gasket on the upper surface of the lower baffle is a frustum-shaped cone.

[0020] 2) Furthermore, the lower end face of the leakage hole of this utility model is a countersunk hole structure, and the sealing gasket on the upper end face of the lower baffle is an inverted T-shaped structure.

[0021] This invention has the advantages of reasonable structure, low cost, and stable and reliable operation. A sealing device is installed between the upper and lower plates, requiring no external power. Under liquid pressure, the leakage hole remains closed during liquid inlet operation and automatically opens after liquid inlet is completed, releasing the liquid from the middle space and preventing liquid waste.

[0027] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present utility model and are not intended to limit its scope of protection. It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which this utility model pertains. Example 1

[0028] like Figure 1 , Figure 2 As shown: A perforated liquid distributor is installed inside the tower 1, including a first plate 2 and a second plate 3, with a middle space between them. The first plate 2 has several first through holes 5, and several first guide pipes 6 and second guide pipes 4 are located between the first plate 2 and the second plate 3. Below one of the first through holes 5, there is a drain hole 10 on the second plate 3. The drain hole 10 has a frustum-shaped cross-section, smaller at the top and larger at the bottom. A circular upper baffle 7 is located above the first through hole 5, and its bottom center is connected to a connecting rod 9. The connecting rod 9 passes through the first through hole 5 and the drain hole 10, and its lower end is connected to the upper center of a circular lower baffle 12 below the second plate 3. The upper surface of the lower baffle 12 also has a cross-section... The sealing gasket 11 is truncated cone-shaped. Upper guide posts 8 are evenly distributed around the first through hole 5 at the upper baffle 7, passing through the edge of the upper baffle 7. A limiting block is provided at the upper end of each upper guide post. Lower guide posts 13 are evenly distributed around the lower end face of the second plate 3 at the leakage hole 10, passing through the edge of the lower baffle 12. A limiting block is provided at the lower end of each lower guide post. The distance between the upper baffle 7 and the lower baffle 12 is greater than the distance between the first plate 2 and the second plate 3 (i.e., the length of the connecting rod 9 is greater than the height between the first plate 2 and the second plate 3). The diameter of the connecting rod 9 is smaller than the diameters of the first through hole 5 and the leakage hole 10, while the diameter of the first through hole 5 is larger than the diameter of the leakage hole 10.

[0029] When the tower of this invention is in use, after the liquid fills the middle space of the first plate 2 and the second plate 3 through the inlet pipe, it enters the upper space above the first plate 2 through several first through holes 5. Because the liquid is continuously injected into the middle space, a certain positive pressure is formed within the middle space. The pressure of the liquid will push the upper baffle 7 upwards. Figure 2 As shown, after the upper baffle 7 is raised, it drives the connecting rod 9 and the lower baffle 12 to move upward, using the sealing gasket 11 to seal the leakage hole 10. When the liquid filling of the tower is completed, the positive pressure of the liquid in the middle space disappears, and under its own gravity, as... Figure 3 As shown, the upper baffle 7, connecting rod 9, and lower baffle 12 fall back to their initial positions, and the liquid in the middle space flows out through the gap between the connecting rod 9 and the leakage hole 10. Example 2

[0030] like Figure 4As shown: the lower end face of the leakage hole 10 is a countersunk hole structure, and the sealing gasket 11 has an inverted T-shaped cross-section. Other aspects are the same as in Example 1.

[0031] This embodiment is used in the same way as embodiment 1.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
