DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-3 A water supply and drainage control valve includes a water inlet pipe 1, a connection box 101 is fixedly connected to the end of the water inlet pipe 1, and a water outlet pipe 102 is fixedly connected to the side wall of the connection box 101, and also includes:

[0022] A first filter plate 2 is fixedly connected to the side wall of the connection box 101 located on one side of the water inlet pipe 1, a connection plate 201 is fixedly connected to the side wall of the first filter plate 2, a second filter plate 202 is fixedly connected to the side wall of the connection plate 201, an elastic component is fixedly connected to the inner wall of the connection box 101, a pressing plate 203 is fixedly connected to the bottom of the elastic component, and a dirt storage chamber 204 and a drainage chamber 205 are provided in the inner cavity of the connection box 101, and the dirt storage chamber 204 is located above the connection plate 201, and the drainage chamber 205 is located below the connection plate 201;

[0023] A connection pipe 206 is fixedly connected to the top of the connection box 101, and a sewage pipe 207 is fixedly connected to the side wall of the connection pipe 206;

[0024] It should be noted that: water is input into the inner cavity of the connecting box 101 through the water inlet pipe 1, and then part of the water will be filtered by the first filter plate 2 and enter the drainage chamber 205 set in the inner cavity of the connecting box 101, and then lead to the water outlet pipe 102. At the same time, under the pressure of water passing through the water inlet pipe 1, the elastic component will be triggered, so that the pressure plate 203 at its bottom slides upward, so the remaining water in the water inlet pipe 1 is mixed with impurities filtered out by the first filter plate 2 and leads to the inner cavity of the sewage storage chamber 204. Then, under the filtering action of the second filter plate 202, clean water will be discharged to the water outlet pipe 102, and impurities will be retained in the sewage storage chamber 204. When there is no water pressure, the elastic component drives the pressure plate 203 back to its original position. At this time, the impurities will stay in the sewage storage chamber 204 and will not flow back to the inner cavity of the water inlet pipe 1. Moreover, the impurities in the inner cavity of the sewage storage chamber 204 can be discharged through the sewage pipe 207 on the side wall of the connecting pipe 206.

[0025] Reference Figure 1-3 The inner wall of the connecting tube 206 is slidably connected with a sliding column 3, and a first spring 301 is fixedly connected between the sliding column 3 and the connecting tube 206;

[0026] The top of the sliding column 3 is fixedly connected with a connecting column 302, the connecting column 302 passes through the connecting pipe 206, and a marking line is set on the side wall of the connecting column 302;

[0027] It should be noted that: when there are too many impurities in the inner cavity of the dirt storage chamber 204, under the action of water pressure, the impurities will gather on the surface of the second filter plate 202, and the second filter plate 202 will be blocked. At this time, under the action of water pressure, the water pressure will squeeze the sliding column 3, and the sliding column 3 will drive the connecting column 302 to slide toward the inner cavity of the connecting pipe 206, and the first spring 301 will be squeezed. At this time, the impurity accumulation in the inner cavity of the dirt storage chamber 204 can be observed through the marking line set on the outer wall of the connecting column 302, that is, the longer the connecting column 302 extends to the outside of the connecting pipe 206, the more the dirt storage chamber 204 is. The more impurities there are in the inner cavity of the sewage chamber 204, the connecting column 302 is manually pulled outward, and the connecting column 302 drives the sliding column 3 to slide toward the inner cavity of the connecting pipe 206 until the sliding column 3 moves above the sewage pipe 207. The impurities in the inner cavity of the sewage storage chamber 204 will be discharged from the sewage pipe 207 along with the water. In addition, when there are too many impurities in the sewage storage chamber 204, under the action of water pressure, when the sliding column 3 slides above the sewage pipe 207, the impurities inside the sewage storage chamber 204 can be discharged automatically. The above can complete the cleaning of the impurities inside the sewage storage chamber 204, which is simple and convenient.

[0028] Reference Figure 1-3 The elastic component includes a sleeve 303 and an extrusion column 304. The sleeve 303 is fixedly mounted on the inner wall of the connection box 101, and the inner wall of the sleeve 303 is slidably connected with the extrusion column 304;

[0029] A second spring 305 is fixedly connected between the end of the extrusion column 304 and the inner wall of the sleeve 303, and the bottom end of the extrusion column 304 is fixedly connected to the pressure plate 203;

[0030] It should be noted that: when the elastic component is triggered, the squeezing column 304 drives the pressure plate 203 to slide toward the inner cavity of the sleeve 303, squeezing the second spring 305. At this time, the pressure plate 203 will open a gap, allowing impurities and water to enter the sewage storage chamber 204. When water is no longer flowing through the water inlet pipe 1, under the action of the rebound force of the second spring 305, the squeezing column 304 drives the pressure plate 203 back to its original position, blocking the gap. At this time, the impurities inside the sewage storage chamber 204 cannot flow back to the inner cavity of the water inlet pipe 1.

[0031] Operation method: water is input into the inner cavity of the connection box 101 through the water inlet pipe 1, and then part of the water will be filtered by the first filter plate 2 and enter the drainage cavity 205 set in the inner cavity of the connection box 101, and then lead to the water outlet pipe 102. At the same time, under the pressure of water flowing through the water inlet pipe 1, the elastic component will be triggered, that is, the squeezing column 304 drives the pressing plate 203 to slide toward the inner cavity of the sleeve 303, squeezing the second spring 305. At this time, the pressing plate 203 will open a gap, and impurities and water can enter the interior of the sewage storage cavity 204. When the water inlet pipe 1 is no longer flowing, under the action of the rebound force of the second spring 305, the squeezing column 304 drives the pressing plate 203 back to its original position to block the gap. At this time, the impurities in the sewage storage cavity 204 cannot flow back to the inner cavity of the water inlet pipe 1, thereby completing the collection of impurities.

[0032] When there are too many impurities in the inner cavity of the dirt storage chamber 204, the impurities will gather on the surface of the second filter plate 202 under the action of water pressure. At this time, the second filter plate 202 will be blocked. At this time, the water pressure will squeeze the sliding column 3 under the action of water pressure. The sliding column 3 will drive the connecting column 302 to slide toward the inner cavity of the connecting pipe 206, and the first spring 301 will be squeezed. At this time, the impurity accumulation in the inner cavity of the dirt storage chamber 204 can be observed through the marking line set on the outer wall of the connecting column 302, that is, the longer the connecting column 302 extends to the outside of the connecting pipe 206, the more the dirt storage chamber 204 is. 04, the more impurities there are in the inner cavity, the connecting column 302 is manually pulled outward, and the connecting column 302 drives the sliding column 3 to slide toward the inner cavity of the connecting tube 206, until the sliding column 3 moves above the sewage pipe 207, and the impurities in the inner cavity of the sewage storage chamber 204 will be discharged from the sewage pipe 207 along with the water. In addition, when there are too many impurities in the sewage storage chamber 204, under the action of water pressure, when the sliding column 3 slides above the sewage pipe 207, the impurities inside the sewage storage chamber 204 can be discharged automatically. The above can complete the cleaning of the impurities inside the sewage storage chamber 204, which is simple and convenient.
