DETAILED DESCRIPTION
[0024] The utility model is further described below in conjunction with embodiments.
[0025] See also Figure 1-5 The utility model provides a water supply and drainage control device, including a water supply and drainage pipe body 1, a first connecting flange 2 is fixedly connected to one side of the water supply and drainage pipe body 1, a second connecting flange 3 is fixedly connected to the other side of the water supply and drainage pipe body 1, a plurality of first fixing bolts 4 are rotatably connected to the inner sides of the first connecting flange 2 and the second connecting flange 3, a filter pipe mouth 5 is fixedly connected to the bottom of the water supply and drainage pipe body 1, a filter cartridge 6 is slidably connected to the inner wall of the filter pipe mouth 5, a mounting plate 7 is fixedly connected to the bottom of the filter cartridge 6, a plurality of second fixing bolts 8 are rotatably connected to the bottom of the mounting plate 7, and a slow flow mechanism 9 is arranged inside the water supply and drainage pipe body 1.
[0026] Further as Figure 4 As shown, it is worth specifically explaining that the water supply and drainage pipe body 1 includes a main body structure layer 101, the outer wall of the main body structure layer 101 is provided with a reinforcement layer 102, the outer wall of the reinforcement layer 102 is provided with an anti-corrosion layer 103, and the inner wall of the main body structure layer 101 is provided with a thermal insulation layer 104. By arranging the reinforcement layer 102, the anti-corrosion layer 103 and the thermal insulation layer 104, it helps to improve the structural strength, durability and operation efficiency of the pipeline, and can also reduce environmental impact and resource waste, which is in line with the principles of sustainable development and the needs of engineering implementation.
[0027] Further as Figure 4As shown, it is worth specifically explaining that the reinforcement layer 102 is made of glass fiber reinforced plastics, which has high strength and rigidity, light weight, low density, is not easy to deform and brittle, can withstand certain external impacts and pressures, and reduces the maintenance frequency and cost of the pipeline system; the anti-corrosion layer 103 is made of epoxy coating, which has extremely strong corrosion resistance and can effectively prevent the pipeline surface from being corroded by chemicals in water, salt in soil and other corrosive substances, which enables the pipeline to operate stably for a long time and reduce the maintenance and replacement frequency. At the same time, the epoxy coating has good coating performance and can be easily applied on site. Compared with other anti-corrosion treatment methods, its construction cost is relatively low and can be implemented quickly, reducing the downtime and operating cost of the pipeline system; the insulation layer 104 is made of extruded polystyrene, which has a closed-cell structure. The unique fine bubble structure can effectively block heat conduction and provide excellent insulation effect, so that the pipeline can effectively prevent cooling water or wastewater from cooling prematurely during transportation in winter, thereby maintaining a stable temperature of the medium in the pipeline, reducing heat loss and preventing the pipeline from condensing and cracking in a low temperature environment.
[0028] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the multiple first fixing bolts 4 are designed to be evenly and symmetrically arranged on the inner side of the first connecting flange 2 and the inner side of the second connecting flange 3. The symmetrical arrangement can ensure that the connecting flanges are evenly distributed when bearing the pipeline pressure, which helps to reduce the stress concentration caused by uneven force and reduce the risk of fatigue damage to the flange and pipeline materials.
[0029] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a block corresponding to the filter cartridge 6 is provided on the top inner surface of the water supply and drainage pipe body 1, and the block cooperates with the filter cartridge 6 to separate the inner wall of the water supply and drainage pipe body 1, thereby ensuring that the impurity particles in the fluid enter the inner wall of the filter cartridge 6 and are blocked and filtered, while the remaining fluid flows out from the through holes on the surface of the filter cartridge 6 and continues to move forward.
[0030] According to the above working process, it can be known that: by setting the filter cartridge 6, the filter cartridge 6 can effectively intercept and remove solid particles, sediments and other impurities in the water, prevent them from entering the inside of the pipeline and equipment, reduce the wear and damage of the pipeline and equipment, and extend their service life; at the same time, by effectively filtering impurities in the water, reducing the accumulation of dirt in the pipeline and equipment, reducing the frequency and cost of maintenance, and improving the stability and reliability of the system.
[0031] Further as Figure 5As shown, it is worth explaining in detail that the flow-delaying mechanism 9 includes a plurality of connecting ears 901 fixedly connected to the inner walls of the front and rear ends of the water supply and drainage pipe body 1, a buffer column 902 is fixedly connected between every two corresponding connecting ears 901, a flow-delaying plate 903 is slidably connected between the two buffer columns 902, a plurality of springs 904 are sleeved on the outer wall of the buffer column 902, and a plurality of water holes 905 are opened on the outer wall of the flow-delaying plate 903. By setting the flow-delaying mechanism 9, the speed and pressure of the water flow can be effectively reduced, thereby reducing the wear and pressure shock of the pipeline and equipment system, which is beneficial to preventing pipeline wear, reducing water flow noise and protecting equipment.
[0032] Further as Figure 5 As shown, it is worth explaining in detail that multiple springs 904 are fixedly connected between the inner side of the connecting ear 901 and the outer wall of the slow flow plate 903. Under the action of the spring 904, the slow flow plate 903 can slide flexibly on the outer wall of the buffer column 902 to avoid excessive impact pressure of the water flow on the slow flow plate 903 and cause damage to it; multiple water holes 905 are evenly distributed on the slow flow plate 903 in a symmetrical manner about the center of the circle. The symmetrical arrangement of the center of the circle can ensure that the speed and direction of the water flow through each water hole 905 are similar, thereby achieving uniform distribution of water flow on the surface of the slow flow plate 903, which helps to reduce turbulence and eddy current phenomena of the water flow, so that the fluid can pass through the slow flow plate 903 smoothly, reducing the impact and loss caused by the water flow.
[0033] This solution has the following working process: in actual use, water flows inside the water supply and drainage pipe body 1, and the filter cartridge 6 filters the large particles of impurities contained in the water flow to prevent them from entering the pipes and equipment and causing wear and damage. The filtered water flows out from the through holes on the surface of the filter cartridge 6 and continues to move forward; when the water flows through the slow flow plate 903, a plurality of evenly distributed water holes 905 enable the water flow to pass smoothly through the slow flow plate 903, effectively slowing down the water flow speed and reducing the kinetic energy of the water flow.
[0034] In summary: by setting up the filter cartridge 6, the filter cartridge 6 can effectively intercept and remove solid particles, sediments and other impurities in the water, prevent them from entering the inside of the pipeline and equipment, reduce the wear and damage of the pipeline and equipment, and extend their service life; at the same time, by effectively filtering impurities in the water, the accumulation of dirt in the pipeline and equipment is reduced, the frequency and maintenance cost of maintenance are reduced, and the stability and reliability of the system are improved; by setting up the slow flow mechanism 9, the speed and pressure of the water flow can be effectively reduced, thereby reducing the wear and pressure shock of the pipeline and equipment system, which is beneficial to preventing pipeline wear, reducing water flow noise and protecting equipment.
