Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a device that can quickly drain residual water from pipelines. Background Technology

[0002] In the daily operation and maintenance of water supply networks, it has been found that in the severe cold of winter, it is necessary to completely drain the water from the pipes each time to prevent residual water from freezing and damaging the pipes. Traditional methods mainly rely on gravity drainage, which has the problems of low drainage efficiency and incomplete drainage. This can easily lead to residual water freezing under low temperatures, causing the pipes to burst. Therefore, this solution proposes a device that can quickly drain residual water from pipes to solve the above problems. Utility Model Content

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention, through the design of connecting a tee, inlet pipe, drainage component, control component, and water supply component, allows the drainage component to be connected to an air compressor when water needs to be drained from the empty pipe.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-4 The device shown can quickly drain residual water from pipes, comprising:

[0024] Connect the tee 1;

[0025] Water inlet pipe 2 is located at one end of the connection tee 1;

[0026] Drainage component 3 is located in the middle of the connecting tee 1;

[0027] Control component 5 is located in the middle of the water inlet pipe 2 and is used to control the direction of water flow.

[0028] Water supply component 4 is located at the other end of the connecting tee 1.

[0029] It should be noted that when it is necessary to drain the water inside the empty pipe, the drain assembly 3 is connected to the air compressor to compress ordinary air into high-pressure, energetic compressed air. The compressed air is then input into the empty pipe, which pushes the water inside the pipe and drains it, thus preventing the water from automatically flowing out and slowly freezing.

[0030] Specifically, the drainage component 3 includes an air inlet pipe 302 located in the middle of the connecting tee 1. One end of the air inlet pipe 302 is provided with a quick connector 303, and the middle of the air inlet pipe 302 is provided with a first gate valve 301. The first gate valve 301 is used to control the passage of liquid and gas through the air inlet pipe 302.

[0031] It should be noted that the first gate valve 301 is an existing device, which is a shut-off valve that controls the opening and closing of the pipeline by raising and lowering the gate. Its core design goal is to achieve complete shut-off or unobstructed flow of fluids and gases throughout the entire flow path. The quick-connect fitting 303 is used to connect the air inlet pipe 302 and the air compressor. When drainage is required, the air inlet pipe 302 is connected to the air compressor through the quick-connect fitting 303, and then the first gate valve 301 is opened, so that the compressed gas can enter the interior of the water supply component 4 through the air inlet pipe 302. After use, the first gate valve 301 is closed, and then the air compressor is separated from the air inlet pipe 302.

[0032] Specifically, the control component 5 includes a check valve 501 located in the middle of the water inlet pipe 2, and a second gate valve 502 located in the middle of the water inlet pipe 2 and on one side of the check valve 501.

[0033] It should be noted that the check valve 501 is an existing device, an automatic valve that ensures unidirectional fluid flow and prevents backflow. Its core components include a valve body, a valve disc, and a valve seat. Its working principle is that when the fluid flows in a preset direction, its pressure will push open the valve disc, overcoming the valve disc's own weight, thus opening the valve and opening the passage. Once the pressure at the inflow end decreases or stops, or even if backflow occurs, the valve disc will automatically and quickly close under its own weight and press tightly against the valve seat, thereby effectively cutting off the passage and preventing the medium from flowing back. The second gate valve 502 works on the same principle as the first gate valve 301 and is used to cut off the flow of liquid inside the inlet pipe 2.

[0034] Furthermore, when it is necessary to drain the water from the pipeline, the second gate valve 502 is closed to prevent water from continuing to enter the pipeline behind the second gate valve 502. Then, the liquid in the pipeline behind the second gate valve 502 is discharged by high-pressure gas, thereby completing the drainage of the pipeline.

[0035] Specifically, the water supply assembly 4 includes a first water supply pipe 401 disposed at the other end of the connecting tee 1, a corrugated pipe 403 disposed on one side of the first water supply pipe 401, a second water supply pipe 405 disposed on one side of the corrugated pipe 403, an outlet 406 disposed on one side of the second water supply pipe 405, a first connector 402 disposed at the connection between the first water supply pipe 401 and the first connector 402, and a second connector 404 disposed at the connection between the corrugated pipe 403 and the second water supply pipe 405.

[0036] It should be noted that both sides of the first connector 402 and the second connector 404 are provided with threads. The first water supply pipe 401, the corrugated pipe 403 and the second water supply pipe 405 are connected through the first connector 402 and the second connector 404. Sealing rings are provided at the connection between the first connector 402 and the first water supply pipe 401 and the corrugated pipe 403, and at the connection between the second connector 404 and the corrugated pipe 403 and the second water supply pipe 405, to prevent water from overflowing from the connection between the pipes and the connectors.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
