Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a valve draining device. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. When existing valves are used for a long time in environments containing impurities, dirt can easily accumulate inside the valve, causing a significant reduction in flow rate. Therefore, if the impurities are not cleaned in time, the valve may become unusable. For example, in sewage treatment plants, valves are prone to scaling inside due to long-term contact with corrosive media. During maintenance, it is necessary to shut down the upstream pipeline, drain the medium, and then disassemble the valve for cleaning. This process not only affects the continuity of production but may also cause scratches on the valve sealing surface due to improper operation, shortening its service life. Another example is in oil extraction systems, where long-term scouring of sandy crude oil can cause sand particles to accumulate in the valve seat sealing groove, preventing the sealing surface from fully adhering when the valve is closed, leading to leakage. Such problems are particularly prominent under frequent opening and closing conditions, so they also need to be disassembled and cleaned regularly. This is not only time-consuming and labor-intensive, but may also damage the sealing surface due to improper operation. However, cleaning the internal deposits of existing valves requires disassembling the valves for maintenance, which is complicated and requires the use of special tools to clean the deposits inside the valve body. Therefore, the cleaning of the device is difficult and the cleaning efficiency is low. Utility Model Content

[0003] This utility model proposes a valve draining device to solve the problem of inconvenient cleaning of existing valves.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a valve sewage discharge device, comprising an inlet component and an outlet component, wherein two filter components are installed between the inlet component and the outlet component, and the inlet component has one inlet end and two outlet ends, and the outlet component has two inlet ends and one outlet end, the filter component includes a water guiding part, the water guiding part is installed between one outlet end of the inlet component and one inlet end of the outlet component, the water guiding part forms a cavity inside, and the top of the water guiding part is open to allow the cavity to communicate with the outside, and a sealing cap for blocking the cavity opening is screwed onto the water guiding part, and a filter component for filtering water is fixedly connected to one side of the sealing cap, the filter component being located inside the cavity.

[0005] Preferably, the water guiding part includes an input pipe, the outlet end of the input pipe is fixedly connected to a base shell, the sealing cap is screwed onto the top of the base shell, and a valve plate is installed on the input pipe. The input pipe is connected to one outlet end of the water inlet component.

[0006] Preferably, a one-way valve is fixedly connected to the bottom of the base shell, and the bottom of the one-way valve is connected to one inlet end of the water outlet component.

[0007] Preferably, the filtering part includes a filter screen, and a connecting rod is fixedly connected to one side of the sealing cover. The free end of the connecting rod is fixedly connected to the filter screen, and the filter screen and the connecting rod are located inside the cavity.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: (1) This utility model is provided with an inlet component, an outlet component, a water guiding part, a sealing cover and a filter part. When in use, the inlet component and the outlet component are respectively connected to the pipe and valve for input water. After the water enters the water guiding part, the filter part intercepts impurities. The filtered water is discharged through the outlet component. When cleaning impurities, it is only necessary to rotate the sealing cover to separate it from the water guiding part, so that the filter part and impurities can be moved out of the water guiding part, thereby achieving efficient sewage discharge. In addition, the device is installed at the liquid inlet end of the valve, which can effectively intercept impurities from entering the valve. The cleaning process does not require disassembling the valve or using special tools, which significantly reduces the difficulty of operation and improves the cleaning efficiency.

[0014] 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.

[0015] like Figures 1-5 As shown, a valve drain device includes an inlet component 1 and an outlet component 2. Two filter elements 3 are installed between the inlet component 1 and the outlet component 2. The inlet component 1 has one inlet end and two outlet ends, and the outlet component 2 has two inlet ends and one outlet end. The filter element 3 includes a water guiding part, which is installed between one outlet end of the inlet component 1 and one inlet end of the outlet component 2. A cavity is formed inside the water guiding part, and the top of the water guiding part is open to allow the cavity to communicate with the outside. A sealing cap 34 for blocking the opening of the cavity is screwed onto the water guiding part. A filter element for filtering water is fixedly connected to one side of the sealing cap 34, and the filter element is located inside the cavity.

[0016] With the above technical solution, before the device is put into use, the water conveying pipe is connected to the inlet end of the water inlet 1, and the outlet end of the water outlet 2 is connected to the valve that needs to be cleaned. The water is conveyed to the water inlet 1 through the water conveying pipe, and the water is guided to the water guiding part through the two outlet ends of the water inlet 1. When the water is conveyed to the filtration part, the water is filtered through the filtration part, so that the impurities in the water are retained above the filtration part. The filtered water is conveyed to the outlet 2 after passing through the filtration part, and the filtered water is discharged through the outlet 2. When it is necessary to clean the impurities in front of the valve, the sealing cover 34 is reversed to separate the sealing cover 34 from the water guiding part. The sealing cover 34 is pulled to move the sealing cover 34 to the outside of the cavity, thereby moving the impurities on the filtration part to the outside of the water guiding part, making it easier to clean the impurities in the device.

[0017] Specifically, in one embodiment, regarding the aforementioned water guiding portion, as... Figure 1 , Figure 2 and Figure 5 As shown, the water guiding part includes an input pipe 35, the outlet end of the input pipe 35 is fixedly connected to a base shell 31, a sealing cover 34 is screwed onto the top of the base shell 31, and a valve plate 36 is installed on the input pipe 35. The input pipe 35 is connected to one outlet end of the water inlet component 1.

[0018] In this embodiment, before personnel need to remove impurities from the water guide section for cleaning, the valve plate 36 corresponding to the base shell 31 from which the impurities need to be removed is closed, so that the input pipe 35 corresponding to the valve plate 36 stops water intake, and the valve plate 36 corresponding to the other input pipe 35 is opened. After the current input pipe 35 stops water intake, the sealing cover 34 on the base shell 31 is rotated to separate the sealing cover 34 from the base shell 31. This allows the sealing cover 34 to move the filter section to the outside of the base shell 31 for cleaning. While personnel are cleaning the dirt, the other input pipe 35 will continue to receive water normally, and the filtered water will be transported normally without the need to stop the machine to clean the dirt.

[0019] When the device is transporting water, in order to prevent water backflow, such as Figure 1 , Figure 2 and Figure 5 As shown, a one-way valve 32 is fixedly connected to the bottom of the base shell 31, and the bottom of the one-way valve 32 is connected to one inlet end of the water outlet component 2.

[0020] In this embodiment, after the filter section in the base shell 31 filters the water, the water flows through the filter section to the bottom of the base shell 31, and is then transported through the base shell 31 to the one-way valve 32. The water is then discharged through the one-way valve 32 to prevent the water from flowing back into the base shell 31.

[0021] Specifically, in one embodiment, regarding the above-mentioned filtering section, such as Figure 1 , Figure 2 and Figure 5 As shown, the filtration section includes a filter screen 37, and a connecting rod 38 is fixedly connected to one side of the sealing cover 34. The free end of the connecting rod 38 is fixedly connected to the filter screen 37, and the filter screen 37 and the connecting rod 38 are located inside the cavity.

[0022] In this embodiment, before the device is put into use, the filter screen 37 is placed inside the base shell 31, and the sealing cover 34 is rotated to screw the sealing cover 34 into the base shell 31, thereby installing the filter screen 37 inside the base shell 31. When the water is delivered to the inlet pipe 35, the water is delivered to the base shell 31 through the inlet pipe 35. The water is filtered through the filter screen 37, so that dirt is retained above the filter screen 37, and the filtered water is discharged through the filter screen 37.

[0023] Furthermore, in this utility model, regarding the aforementioned water inlet component 1, as follows: Figures 1-3As shown, the water inlet 1 includes a first water guide pipe 11, the two ends of the first water guide pipe 11 are fixedly connected to two input pipes 35 respectively, and the circumference of the first water guide pipe 11 is fixedly connected to a water inlet pipe 12.

[0024] In this embodiment, the water input pipe is connected to the water inlet pipe 12. After the water is transported to the water inlet pipe 12, it is guided to the first water guide pipe 11 through the water inlet pipe 12. The water is then transported to the input pipe 35 through the first water guide pipe 11. Finally, the water is input to the base shell 31 for filtration through the input pipe 35.

[0025] Specifically, in one embodiment, regarding the aforementioned water outlet 2, as... Figure 1 , Figure 2 and Figure 4 As shown, the water outlet component 2 includes a second water guide pipe 21, with both ends of the second water guide pipe 21 fixedly connected to two one-way valves 32, and a water outlet pipe 22 fixedly connected to the circumference of the second water guide pipe 21.

[0026] In this embodiment, after the water is filtered, it is transported to the one-way valve 32, which then transports the water to the second water guide pipe 21. The second water guide pipe 21 guides the water to the outlet pipe 22, and the filtered water is discharged through the outlet pipe 22.

[0027] Furthermore, in this invention, in order to improve the water discharge efficiency in the base shell 31, such as... Figure 1 , Figure 2 and Figure 5 As shown, the interior of the base shell 31 slopes downward to form a flow guide slope 33.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
