Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve sewage discharge structure. Background Art

[0002] A valve is a device used to control the flow of media such as liquids or gases. In order to ensure the normal flow of the valve, a drain structure is generally set on the valve to discharge impurities accumulated in the valve through the drain structure. The flow and pressure of the liquid or gas in the valve can be controlled by the operating device, making the discharge more accurate and controllable.

[0003] A Chinese patent with application number CN202021978177.6 discloses a valve sewage discharge structure, which is equipped with an outlet pipe, which is "L"-shaped and used in conjunction with a valve body. The valve body discharges sewage into the outlet pipe. When the sewage is discharged outward from the inside of the outlet pipe, there will be a buffer due to its "L"-shaped shape, giving maintenance personnel enough time to retreat after turning the handwheel and opening the valve, thereby preventing hot water from flowing out directly when the valve is directly opened, causing harm to the maintenance personnel. However, when the above-mentioned valve body sewage discharge structure is in use, impurities in the water inlet pipe are blocked by bars. However, when the blocked impurities are discharged, the discharge pipe is easily blocked, which makes it difficult to discharge the impurities in the valve body, thereby increasing the failure rate and possibility of damage of the valve body, making the maintenance and replacement work more frequent, and at the same time increasing the wear and loss of the valve body structure, affecting the use of the valve body.

[0028] The utility model provides Figure 1-Figure 4A valve sewage discharge structure shown in the figure comprises: a valve body 1, a valve core 8 is installed inside the valve body 1, and an inlet pipe 2 and a drain pipe 3 are respectively connected to both sides of the valve body 1, a driving mechanism for driving the valve core 8 to rotate is arranged between the valve core 8 and the valve body 1, the driving mechanism comprises a fixing rod fixed to the top of the valve core 8 and a rotating disk 4 arranged on the top of the valve body 1, the fixing rod extends to the top of the valve body 1 and is fixed to the rotating disk 4, a fixing mechanism 5 for fixing the inlet pipe 2 and the drain pipe 3 is arranged on one side of the valve body 1, the fixing mechanism 5 comprises a connecting seat 51 fixed to one side of the valve body 1 and a fixing plate 52 installed on one side of the connecting seat 51, a plurality of evenly distributed threaded holes are opened on the outside of the fixing plate 52, a connecting mechanism is arranged between the inlet pipe 2 and the drain pipe 3 and the connecting seat 51, the connecting mechanism comprises a rod body fixed to both sides of the connecting seat 51 and connecting rods 53 respectively connected to one side of the inlet pipe 2 and the drain pipe 3, and a reinforcement rod 54 is fixed between the two connecting rods 53 and the rod body.

[0029] As can be seen from the above, when in use, align the fixing plate 52 with the place where it needs to be fixed, and fix the fixing plate 52 through multiple threaded holes. By fixing the fixing plate 52, the connecting seat 51 is fixed synchronously, and the valve body 1 can be effectively fixed by fixing the connecting seat 51. Then, connect the water inlet pipe 2 to the place where sewage needs to be discharged, rotate the rotating disk 4 to drive the fixing rod to rotate, and drive the valve core 8 to rotate through the rotation of the fixing rod, so that the sewage flows into the drain pipe 3 through the valve body 1, so that the sewage can be effectively discharged. By setting the connecting rod 53 and the reinforcement rod 54, it can be ensured that the connection between them and the valve body 1 is firm and stable, and will not loosen or fall off due to pipeline force or other factors. At the same time, it can effectively prevent water leakage or leakage problems.

[0030] refer to Figure 1 , Figure 2 and Figure 5 As shown, the discharge mechanism 6 is located inside the drain pipe 3, and the discharge mechanism 6 includes a filter plate 61 fixed inside the drain pipe 3 and an extension seat 65 installed on the top of the drain pipe 3, an open groove is opened between the extension seat 65 and the drain pipe 3, a scraping mechanism for scraping one side of the filter plate 61 is arranged between the filter plate 61 and the open groove, a discharge plate 62 is hinged on one side of the drain pipe 3, the scraping mechanism includes a threaded rod 64 rotatably connected to the inside of the open groove, the threaded rod 64 extends to one side of the drain pipe 3 and is fixed with a rotating knob, and a pushing mechanism for pushing dirt accumulated on one side of the filter plate 61 is arranged between the threaded rod 64 and the filter plate 61, the pushing mechanism includes a scraper 63 installed inside the drain pipe 3 and a moving block screwed to the outer wall of the threaded rod 64, the scraper 63 is fixed to the moving block, and the scraper 63 corresponds to the discharge plate 62.

[0031] Through the above technical solution:

[0032] When sewage is discharged from the drain pipe 3, the filter plate 61 can block larger particles of impurities in the sewage. When there are more impurities accumulated on one side of the filter plate 61, close the valve core 8, open the discharge plate 62, turn the rotary knob to drive the threaded rod 64 to rotate, and the rotation of the threaded rod 64 drives the moving block to start moving, and the movement of the moving block drives the scraper 63 to move. The movement of the scraper 63 can effectively push the impurities on one side of the filter plate 61 until it is pushed to the discharge plate 62, so that the accumulated impurities can be cleaned. The scraper 63 is set to keep the impurities discharged unimpeded, avoiding the situation that the drain pipe 3 is blocked during discharge, thereby reducing the failure rate and damage possibility of the valve body 1, reducing the frequency of maintenance and replacement work, and reducing the wear and loss of the valve body 1, ensuring the normal use of the valve body 1.

[0033] In addition, refer to Figure 2 and Figure 3 As shown, cleaning mechanisms 7 for cleaning the interior of the valve body 1 are provided on both sides of the valve core 8. The cleaning mechanism 7 includes a mounting sleeve 71 fixed on one side of the valve core 8 and a cleaning cotton 72 fixed on one side of the mounting sleeve 71. A guide plate 73 is connected between the cleaning cotton 72 and the mounting sleeve 71, and the guide plate 73 corresponds to the interior of the valve core 8.

[0034] Through the above technical solution:

[0035] When the valve core 8 is rotated and adjusted, the rotation of the valve core 8 drives the installation sleeve 71 to rotate, and the rotation of the installation sleeve 71 drives the cleaning cotton 72 to rotate. The rotation of the cleaning cotton 72 allows the interior of the valve body 1 to be effectively scraped. After scraping the interior of the valve body 1, the scraped dirt can be discharged through the drain pipe 3, thereby cleaning the interior of the valve body 1, which helps to reduce the loss of flow resistance and pressure, improve the fluidity and work efficiency, reduce energy consumption, avoid corrosion and wear, reduce maintenance and replacement costs, further prevent blockages and failures inside the valve body 1, and avoid safety hazards and accidents caused by problems with the valve body 1.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
