Description

Technical Field

[0001] The utility model relates to the technical field of water distributors, in particular to a pull-valve water distributor. Background Art

[0002] Currently, water storage tanks on the market all utilize a structure consisting of a main inlet and outlet pipe and a branch distribution pipe (single or multi-stage). Conventional pipes (such as stainless steel, galvanized pipe, PVC, or other materials) are used from the initial distribution point to the final distribution point, with the pipes arranged in a multi-stage H-shaped pattern. The intermediate distribution pipes continuously branch to distribute the water flow until the final distribution point.

[0003] There are many existing technologies for pull valve water distributors, such as:

[0004] Chinese patent publication number CN211233208U discloses an induced drainage type water distribution container, comprising a gravity flow water distribution container, a water inlet pipe, and a water outlet pipe. The center of the bottom of the water distribution chamber is provided with a raised drainage body. The water inlet at the middle of the upper end of the water distribution chamber is connected to a water inlet pipe extending deep into the chamber near the bottom. The circumferential side wall of the water distribution chamber is provided with at least three water outlets evenly distributed on a circumference. Because the raised drainage body is provided at the center of the bottom of the induced drainage type water distribution container, water flows directly into the bottom of the water distribution chamber through the water inlet pipe. The raised drainage body at the bottom of the water distribution chamber spreads the water evenly around the bottom of the water distribution chamber, reducing the speed of the water flow and stabilizing the flow state to form a thinner water distribution layer. This continuously squeezes the original water flow in the water distribution chamber upward in a piston-like manner, not only reducing the turbulent mixing of cold and hot water flows in the water distribution chamber, but also avoiding the formation of residual dead water areas, thereby improving water distribution efficiency.

[0005] It can be seen from this that most pull-valve water distributors include gravity flow water distribution containers. By arranging a raised drainage body in the gravity flow water distribution container, the new water entering the water distribution cavity is squeezed out in a piston-like manner through the drainage body, reducing the turbulence of cold and hot water flows in the water distribution cavity and the residual dead water area. However, the above-mentioned patent actually uses the principle of communicating vessels to realize the discharge of water from the water distribution cavity to the branch pipe. When using the principle of communicating vessels, after the equipment stops supplying water to the water distribution cavity, there will inevitably be a part of residual water in the water distribution cavity. If this part of residual water is not treated, it is easy to form a dead water area. At the same time, the water distribution container is usually buried deep underground. If the residual water is led out of the water distribution container and discharged directly, it will affect the stability of the water distribution container.

[0006] In view of this, we propose a pull-valve water distributor. Summary of the Invention

[0007] The purpose of the present utility model is to solve the above-mentioned shortcomings and provide a pull-valve water distributor for removing residual water in a water distribution chamber.

[0008] When the utility model is in use, a lifting component is provided at the bottom of the drainage chamber, and the lifting component is used to separate the drainage body from the bottom of the drainage chamber, so that the residual water in the drainage chamber enters the drainage chamber for centralized treatment, thereby avoiding the formation of a dead water area in the drainage chamber; and a drainage component is provided in the drainage chamber, and the drainage component is used to discharge the water discharged into the drainage chamber to the outside, thereby avoiding direct discharge to the periphery of the water distributor component and affecting the stability of the water distributor component.

[0009] Therefore, the utility model provides a pull-valve water distributor, including a water distributor assembly, the water distributor assembly including a shell, the shell is hollow, and the shell is sequentially provided with a drainage chamber and a drainage chamber from top to bottom. A drainage body is provided at the bottom of the drainage chamber, and a lifting assembly for lifting the drainage body is provided in the drainage chamber. The drainage chamber is provided with a drainage assembly for lifting the drainage body and then discharging the water discharged into the drainage chamber from the drainage chamber.

[0010] As a further improvement of the present technical solution, a water inlet pipe for injecting water into the drainage cavity is provided on the top of the shell, and a plurality of branch pipes for draining water are provided around the drainage cavity.

[0011] As a further improvement of this technical solution, a bottom plate is provided at the bottom of the drainage cavity, the bottom plate is provided with a card slot, and a card block is provided at the bottom of the drainage body. The card block of the drainage body is carded in the card slot to close the bottom of the drainage cavity.

[0013] As a further improvement of the present technical solution, the drainage assembly includes a water pump fixed at the bottom of the drainage chamber and an external pipe fixed at one end of the water pump discharge port and connected to the outside world.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the pull-valve water distributor, a lifting assembly is provided at the bottom of the drainage chamber, and the lifting assembly is used to separate the drainage body from the bottom of the drainage chamber, so that the residual water in the drainage chamber enters the drainage chamber for centralized treatment, thereby avoiding the formation of a dead water area in the drainage chamber.

[0016] In the pull-valve water distributor, a drainage assembly is provided in the drainage cavity, and the drainage assembly is used to discharge the water discharged into the drainage cavity to the outside, thereby avoiding direct discharge to the periphery of the water distributor assembly and affecting the stability of the water distributor assembly.

[0023] Most pull-valve water distributors include gravity flow water distribution containers. By arranging a raised drainage body in the gravity flow water distribution container, the new water entering the water distribution cavity squeezes the original water flow upward in a piston-like manner through the drainage body, reducing the turbulence of cold and hot water flows in the water distribution cavity and the residual dead water area. However, the above-mentioned patent actually uses the principle of communicating vessels to discharge water from the water distribution cavity to the branch pipe. When using the principle of communicating vessels, after the equipment stops supplying water to the water distribution cavity, there will inevitably be a part of residual water in the water distribution cavity. If this part of residual water is not treated, it is easy to form a dead water area. At the same time, the water distribution container is usually buried deep underground. If the residual water is led out of the water distribution container and discharged directly, it will affect the stability of the water distribution container.

[0024] like Figures 1-4 As shown, this embodiment provides a pull-valve water distributor, including a water distributor assembly 1. The water distributor assembly 1 includes a shell 11, which is hollow. The shell 11 contains a drainage chamber 113 and a drainage chamber 114 from top to bottom. A drainage body 122 is provided at the bottom of the drainage chamber 113. Considering that there will be residual water in the drainage chamber 113 after the water supply is stopped, a lifting assembly 12 is provided in the drainage chamber 114 to lift the drainage body 122. Considering that discharging the residual water to the surroundings of the water distributor assembly 1 may affect the stability of the water distributor assembly 1, the drainage chamber 114 is provided with a drainage assembly 13 to drain the water discharged from the drainage chamber 113 into the drainage chamber 114 after lifting the drainage body 122.

[0025] The improvement of this embodiment lies in that: by arranging a lifting component 12 at the bottom of the drainage chamber 113, the lifting component 12 is used to separate the drainage body 122 from the bottom of the drainage chamber 113, allowing the residual water in the drainage chamber 113 to enter the drainage chamber 114 for centralized treatment, avoiding the formation of a dead water area in the drainage chamber 113, and by arranging a drainage component 13 in the drainage chamber 114, the drainage component 13 is used to discharge the water discharged into the drainage chamber 114 to the outside, avoiding direct discharge to the surroundings of the water distributor component 1, which affects the stability of the water distributor component 1.

[0026] Considering the detailed introduction of the water distributor assembly 1 and the drainage process, the second embodiment of the present utility model is shown.

[0027] The top of the housing 11 is provided with a water inlet pipe 111 for injecting water into the drainage chamber 113. A plurality of branch pipes 112 for draining water are provided around the drainage chamber 113. The principle of a communicating vessel is used to drain water from the water inlet pipe 111 to the branch pipes 112 in the drainage chamber 113. A bottom plate 115 is provided at the bottom of the drainage chamber 113. The bottom plate 115 is provided with a card slot 116. A card block is provided at the bottom of the drainage body 122. The card block of the drainage body 122 is carded in the card slot 116, so that the bottom of the drainage chamber 113 is closed, thereby To prevent water leakage in the drainage chamber 113 during operation, the lifting assembly 12 includes a hydraulic rod 121 fixed to the bottom of the drainage body 122. A protective shell 117 is provided around the hydraulic rod 121 to protect the hydraulic rod 121 and prevent water discharged into the drainage chamber 114 from hitting the hydraulic rod 121 and causing damage to the hydraulic rod 121. The drainage assembly 13 includes a water pump 131 fixed to the bottom of the drainage chamber 114 and an external pipe 132 fixed to one end of the discharge outlet of the water pump 131 and connected to the outside world.

[0028] In summary, the working principle of this solution is as follows:

[0029] The water distributor assembly 1 is installed underground, and one end of the external pipe 132 of the drainage assembly 13 is extended out of the ground, and water is injected into the drainage chamber 113 through the water inlet pipe 111. After a certain amount of water is injected, the injected water is discharged to the branch pipe 112 due to the principle of communicating vessels. When the water distribution operation is completed, the water injection into the water inlet pipe 111 is stopped, and the hydraulic rod 121 is started so that the piston rod of the hydraulic rod 121 pushes out the drainage body 122, so that the drainage body 122 is separated from the bottom plate 115 at the bottom of the drainage chamber 113, forming a channel for discharging the residual water in the drainage chamber 113 to the drainage chamber 114. At the same time, the water pump 131 is started to discharge the water in the drainage chamber 114 to the ground through the external pipe 132 through the water pump 131.
