Abstract
Description
Technical Field
[0001] This utility model relates to the field of water environment management technology, specifically to an integrated sampling and venting valve for municipal drainage pipeline systems. Background Technology
[0002] Municipal drainage pipe systems are a crucial component of urban infrastructure, responsible for collecting and transporting rainwater, domestic sewage, and industrial wastewater. With rapid urbanization, the scale and complexity of drainage pipe systems are constantly increasing, making their proper operation vital for urban environmental protection, public health, and residents' quality of life. Municipal drainage pipe systems face numerous challenges in actual operation, such as pipe blockage, water pollution, and inconvenient maintenance. To effectively manage and maintain these pipes, regular inspection, sampling, and cleaning are essential. Traditional sampling and emptying operations typically require separate equipment, which not only increases operational complexity and cost but also leads to low efficiency.
[0003] Traditional municipal drainage systems do not have drainage measures designed for emptying, but drainage systems often contain particulate matter such as stones, which can easily accumulate and cause pipe blockages during operation. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated sampling and venting valve for municipal drainage pipeline systems. This valve can perform sampling and venting of municipal drainage systems in one integrated manner.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A sampling and venting integrated valve for municipal drainage pipeline systems includes a V-shaped pipe with a bending angle between 120° and 175°. A branch pipe is laterally connected to the bend of the V-shaped pipe, and a sampling port is connected downwards at the bottom of the branch pipe. A valve seat is connected to the end of the branch pipe, and a valve core is sealed and penetrated inside the valve seat. One end of the valve core is threaded, and the other end is inserted into the branch pipe. A rotating wheel is also rotatably connected to the valve seat, and the rotating wheel is threaded to the valve core. After the rotating wheel rotates, it drives the valve core to move within the branch pipe to open or close the sampling port.
[0007] Preferably, the valve seat includes a base and a top plate, the top plate and the base are connected by four studs, the base is connected to the end of the branch pipe, and the wheel is connected to the top plate.
[0008] Preferably, the end of the valve core located inside the branch pipe is constructed as an arc-shaped surface so that the valve core can fit into the V-shaped pipe after it moves.
[0009] Preferably, the two ends of the V-shaped tube are connected to a tube.
[0010] Preferably, the rotary wheel includes a turntable and a handle connected to the turntable, and the handle has an adjustable rotating sleeve.
[0011] Preferably, the V-shaped pipe, branch pipe, and valve core are made of stainless steel.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The V-shaped pipe designed in this utility model provides the lowest point for the drainage pipe after it is connected to the drainage system. On the one hand, the particles and debris such as stones mixed in the drainage system will be deposited at this point. The valve can be opened periodically to drain the deposited debris from the drainage system. At the same time, the valve can be opened to take samples from the sampling port as needed, so as to facilitate the sampling and testing of the water quality of the drainage system.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0020] As a preferred embodiment of this utility model, this embodiment provides a sampling and venting integrated valve for municipal drainage pipeline systems, such as... Figures 1-4As shown, it includes a V-shaped tube 1, the bending angle α of which is between 120° and 175°. A branch tube 2 is laterally connected to the bend of the V-shaped tube 1. A sampling port 3 is connected downward at the bottom of the branch tube 2. A valve seat 4 is connected to the end of the branch tube 2. A valve core 5 is sealed and penetrated inside the valve seat 4. One end of the valve core 5 is threaded, and the other end is inserted into the branch tube 2. A rotating wheel 6 is also rotatably connected to the valve seat 4. The rotating wheel 6 is threaded to the valve core 5. After the rotating wheel 6 rotates, it is used to drive the valve core 5 to move inside the branch tube 2 to open or close the sampling port 3.
[0021] In the above embodiments, the bending angle α of the V-shaped pipe 1 is between 120° and 175°, preferably 160°, 165°, 170°, etc. When the particles mixed in the water are few or have low density, bending angles of 120°, 120°, 140°, or 150° can be used. This can promote the concentrated deposition of low-density small particles, facilitating centralized drainage. Overall, using a large-angle bend can create a trough in the drainage pipe system, allowing particles such as stones in the water to deposit there, achieving rapid drainage. It also avoids a large pressure drop at the bend in the drainage system, preventing pipe pressure or drainage problems. Figure 1 and Figure 2 As shown, sampling port 3 can be designed as a slope, or it can be designed as a flexible sampling port or other structural forms, based on the principle of adapting to the needs of on-site use.
[0022] In some embodiments, as Figures 1-3 As shown, the valve seat 4 includes a base 7 and a top plate 8. The top plate 8 and the base 7 are connected by four studs 9. The base 7 is connected to the end of the branch pipe 2, and the rotating wheel 6 is connected to the top plate 8.
[0023] In some preferred embodiments, such as Figure 4 As shown, the valve core 5 is constructed with an arc-shaped surface at one end inside the branch pipe 2, so that the valve core 5 can form a fitting state with the V-shaped pipe 1 after it moves. It should be noted that the above-mentioned fitting state means that the end of the valve core 5 and the connecting pipe opening on the V-shaped pipe 1 are exactly or nearly complementary. When the valve core 5 moves to its end and fits with the inner wall of the V-shaped pipe 1, the V-shaped pipe has exactly or nearly a complete inner wall surface. This design can avoid the formation of local vortices at the fitting point of the valve core 5 and the V-shaped pipe 1, which would cause vortices, turbulence and other flow fields that are not conducive to drainage.
[0024] In some other preferred embodiments, in order to facilitate the connection and installation of the valve 1 with the drainage system, and to facilitate later inspection and maintenance, the two ends of the V-shaped pipe 1 in this embodiment are connected with pipe flanges, so that it can be quickly and detachably connected to the pipeline system. The pipe flanges are standard pipe fittings and are not shown in the drawings of this patent.
[0025] In some embodiments, as Figure 3 and Figure 4 As shown, to facilitate emptying and sampling operations, the rotating wheel 6 in this embodiment includes a turntable 10 and a handle 11 connected to the turntable 10. The handle 11 is equipped with a rotating sleeve 12. During sampling and emptying, the wheel can be rotated, or it can be rotated using the handle connected to the wheel.
[0026] In some preferred embodiments, considering the uncontrollable acidity and alkalinity in the drainage system, in order to improve corrosion resistance and extend service life, the V-shaped pipe 1, branch pipe 2 and valve core 5 described in this embodiment are made of stainless steel.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
