Description

Technical Field

[0001] The utility model belongs to the technical field of odor-proof valves, in particular to a three-way independent sewage discharge odor-proof valve device. Background Art

[0002] The 3-way independent sewage and odor prevention valve device is a valve device used to control the pipeline system of three different paths. It is mainly used to prevent sewage, wastewater and other pollutants from generating odor during the discharge process and to prevent the backflow of pollutants. This device usually includes multiple independently controlled channels, each channel has its own valve to ensure that the sewage discharge and odor prevention functions of each path operate independently.

[0003] The existing three-way independent sewage and odor-proof valve device is inserted into the interior of the sewage pipe through a plug tube. However, since the plug tube is exposed to sewage and chemicals for a long time, the plug tube material will gradually corrode, resulting in a decrease in sealing performance, causing a gap and looseness in the connection between the plug tube and the sewage pipe, which will cause the odor-proof function of the odor-proof valve to fail, and then cause odor to overflow, affecting environmental hygiene and user experience. Utility Model Content

[0004] In view of this, the utility model addresses the deficiencies of the existing technology and provides a three-way independent sewage and odor-proof valve device, which is equipped with a tight sealing mechanism for the odor-proof valve, so that the plug tube and the sewage pipe are tightly connected together through the resilience of the spring. When the plug tube is corroded and damaged, its sealing and odor-proof properties can still be maintained, thereby improving environmental hygiene and user experience.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a 3-way independent sewage and odor-proof valve device, including a cavity shell, a cover plate is clamped on the upper end of the cavity shell, three valve bodies are arranged in the three mounting holes opened inside the cavity shell, valve plates are rotatably arranged on the left sides of the three valve bodies, pipes are rotatably arranged inside the two valve bodies located on the rear side, a sealing disk is clamped inside the valve body located on the front side, a plug tube is arranged in the sewage outlet opened at the lower end of the cavity shell, and a sealing mechanism for sealing the odor-proof valve is arranged on the outer arc surface of the plug tube, and the odor-proof valve is tightly sealed. The mechanism includes a rectangular plate fixedly mounted on the outer arc surface of the plug tube, sliding columns are slidably arranged on the front and rear sides of the interior of the rectangular plate, the front and rear positions of the two sliding columns correspond, rectangular blocks are arranged at the lower ends of the two sliding columns, locking columns are slidably arranged inside the two rectangular blocks, pull plates are arranged on the outer ends of the two locking columns, two pulling racks are arranged between the two rectangular blocks, an elastic driving unit is arranged between the rectangular block and the rectangular plate, the elastic driving unit includes a spring arranged between the rectangular block and the rectangular plate, and the two springs are respectively mounted on the outer arc surfaces of the corresponding sliding columns.

[0006] As a further improvement of the present invention, an interception frame is provided inside the cavity shell.

[0007] As a further improvement of the present invention, a sealing ring is provided at the lower end of the rectangular block and is installed in cooperation with the plug tube. The sealing ring and the rectangular block are fixed by bonding.

[0008] As a further improvement of the present invention, a plurality of anti-skid protrusions are provided on the outer arc surface of the pull plate, an anti-skid pad is provided on the upper end of the pull frame, and the pull frame and the protective pad are fixed by bonding.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] First, by inserting the stopper tube into the interior of the sewage pipe, and then pulling the pull racks on both sides, the locking column on the rectangular block moves downward, and the locking columns on both sides correspond to the locking holes on the sewage pipe, and then the pull plates are pushed in turn to insert the locking columns into the locking holes opened on the outer arc surface of the sewage pipe, and then the pull racks are released. A tight sealing mechanism of an odor-proof valve is provided, so that the stopper tube and the sewage pipe are tightly connected together through the resilience of the spring. When the stopper tube is corroded and damaged, it can still maintain its sealing and odor-proof properties, thereby improving environmental hygiene and user experience.

[0011] Secondly, when people push the pull plate, the anti-slip protrusions can increase the friction to prevent people from slipping. At the same time, when pulling the pull rack, the anti-slip pad can also effectively prevent people from slipping, making it easier for people to install the odor-proof valve.

[0012] Thirdly, by connecting the pipe to the external sewage pipe, the sewage is transported to the interior of the valve body. The sewage enters the interior of the cavity shell through the impact valve plate and enters the interior of the sewage pipe through the plug tube. If the sewage stops being transported, the gate will quickly close and fit the valve body to prevent odor from leaking through the valve body. The flexibly rotatable pipe makes it more convenient for personnel to connect sewage pipes at different locations. When a certain pipe is not in use, it can be sealed by a sealing disk to further prevent the possibility of odor leakage when the other pipes are in use, thereby improving the adaptability of the odor-proof valve.

[0013] Fourthly, the interception frame can intercept the debris inside the sewage transported by the three valve bodies, and then the cover plate can be removed from the cavity shell to take out the debris intercepted inside, which can prevent the debris from clogging the subsequent sewage pipe and further prevent the odor leakage caused by the blockage.

DETAILED DESCRIPTION

[0020] To better understand the present invention, the following examples further illustrate the present invention. However, the present invention is not limited to the following examples. In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be practiced without one or more of these details.

[0021] like Figure 1 、 2 As shown in Figure 4, a three-way independent sewage and odor-proof valve device includes a cavity shell 101, a cover plate 102 is clamped on the upper end of the cavity shell 101, three valve bodies 104 are provided in the three mounting holes opened in the interior of the cavity shell 101, valve plates 108 are rotatably provided on the left sides of the three valve bodies 104, connecting pipes 105 are rotatably provided in the interiors of the two valve bodies 104 located on the rear side, a sealing disk 106 is clamped in the interior of the valve body 104 located on the front side, a plug tube 103 is provided in the sewage outlet opened at the lower end of the cavity shell 101, and an odor-proof valve tight sealing mechanism for sealing is provided on the outer arc surface of the plug tube 103, and a sealing ring 205 is provided at the lower end of the rectangular block 210 for mounting in conjunction with the plug tube 103.

[0022] like Figure 1 、 2As shown in , 3 and 4, the tight sealing mechanism of the odor-proof valve includes a rectangular plate 201 fixedly sleeved on the outer arc surface of the stopper tube 103, and sliding columns 208 are slidably provided on the front and rear sides of the interior of the rectangular plate 201, and a rectangular block 210 is provided at the lower end of the two sliding columns 208. The front and rear positions of the two rectangular blocks 210 correspond, and locking columns 207 are slidably provided inside the two rectangular blocks 210. A pull plate 203 is provided on the outer end of the two locking columns 207, and two pull racks 202 are provided between the two rectangular blocks 210. An elastic driving unit is provided between the rectangular block 210 and the rectangular plate 201, and the elastic driving unit includes a spring 206 arranged between the rectangular block 210 and the rectangular plate 201. The two springs 206 are respectively sleeved on the outer arc surfaces of the corresponding sliding columns 208, and a plurality of anti-slip protrusions 209 are provided on the outer arc surface of the pull plate 203, and an anti-slip pad 204 is provided on the upper end of the pull rack 202.

[0023] When the odor-proof valve needs to be installed, the plug tube 103 is inserted into the interior of the sewage pipe, and then the pull racks 202 on both sides are pulled to move the locking posts 207 on the rectangular block 210 downward, and the locking posts 207 on both sides correspond to the locking holes on the sewage pipe. Then, the pull plate 203 is pushed in turn to insert the locking posts into the locking holes opened on the outer arc surface of the sewage pipe, and then the pull rack 202 is released. The resilience of the spring 206 allows the rectangular plate 201 and the sewage pipe to maintain a tight seal with the sewage pipe through the sealing ring 205 when the plug tube 103 is corroded, thereby preventing odor leakage. When pushing the pull plate 203, the anti-slip protrusion 209 can increase the friction to prevent people from slipping. At the same time, when pulling the pull rack 202, the anti-slip pad 204 can also effectively prevent people from slipping.

[0024] By connecting the connecting pipe 105 to an external sewage pipe, the sewage is transported to the interior of the valve body 104. The sewage enters the interior of the cavity shell 101 through the impact valve plate 108 and enters the interior of the sewage pipe through the plug tube 103. If the sewage stops being transported, the gate plate will quickly close and fit into the valve body 104 to prevent odor from leaking through the valve body 104. The flexibly rotatable connecting pipe 105 makes it more convenient for personnel to connect sewage pipes at different locations. When a certain connecting pipe 105 is not in use, it can be sealed by the sealing disk 106 to further prevent the possibility of odor leakage when the remaining connecting pipes 105 are in use.

[0025] According to another embodiment of the present invention, Figure 4 As shown, an interception frame 107 is provided inside the cavity shell 101, through which the debris inside the sewage transported by the three valve bodies 104 can be intercepted. Then the cover plate 102 can be removed from the cavity shell 101, and the debris intercepted inside can be taken out, which can prevent the debris from clogging the subsequent sewage pipe.
