Abstract
Description
Technical Field
[0001] The invention relates to an integrated water seal, in particular to an integrated water seal used for converting drainage from different floors of a building into drainage on the same floor. Background Art
[0002] The bathrooms, kitchens and balconies of traditional old buildings are mostly equipped with different-level drainage. When the drainage pipes of one's own home need to be updated, renovated or repaired, it is necessary to enter the lower space, which harms the interests of the lower-level owners. When the different-level drainage is to be changed to the same-level drainage, the ground floor slab of this level needs to be raised. When the ground floor slab is required to remain the same as the original one without being raised, holes need to be chiseled in the ground floor slab of this level, and after the same-level drainage integrated water seal is installed, drainage risers need to be installed, holes need to be filled, and drainage horizontal branches need to be installed. As a result, the same-level drainage renovation of one's own household on this level affects the normal life of the lower-level owners and is likely to cause neighborhood disputes. However, due to the limitations of water seal height, flow channel width, drainage inlet height from the ground, drainage outlet height from the ground, drainage safety, and patency, the ground floor slab needs to be raised to achieve the same-level drainage renovation. Summary of the invention
[0003] The present invention aims to overcome the defects of the prior art and provides an integrated water seal for converting different-layer drainage to same-layer drainage, which is used for the renovation of old buildings or the renovation of the same-layer drainage of bathrooms, kitchens and balconies in new buildings that have adopted different-layer drainage. There is no need to drill through the floor slab, enter the lower space, and affect the normal life of the owners of the lower households. The ground floor slab of the current floor does not need to be raised, and the same-layer drainage renovation can be easily achieved in the households of the current floor.
[0004] The integrated water seal for converting different-layer drainage into same-layer drainage of the present invention comprises a body, a drainage inlet, a drainage outlet, a water seal baffle, and a first inspection port. The bottom of the body is closed, and the upper part is provided with a drainage inlet, a drainage outlet, a first inspection port and a water seal baffle; the water seal baffle divides the inner wall of the body into two first channels and a second channel which are closed at the upper and side parts and connected at the bottom, and the maximum width of each channel is not greater than 200 mm, the minimum width is not less than 20 mm, and the water flow cross-sectional area is not less than 1500 mm2; the drainage inlet and the first inspection port are both located on the first channel; the drainage outlet is located on the second channel, and the inner diameter is 6 The drainage outlet is between 0mm-80mm, and there is a baffle on the drainage outlet. The baffle is between 15mm-45mm higher than the lowest point of the drainage outlet, and the water-passing cross-sectional area of the connecting channel formed by the baffle and the inner wall of the drainage outlet is greater than 1500mm2. Therefore, by increasing the inner diameter of the drainage outlet (generally using an inner diameter of 75mm), the baffle is used to partially close the bottom of the drainage outlet to ensure that the drainage channel reaches the minimum water-passing cross-sectional area, thereby achieving the minimum drainage flow of gravity flow discharge under the rated submergence height, so as to reduce the distance between the drainage outlet and the drainage inlet without affecting or improving the drainage smoothness. The height of the bottom of the water seal body is formed to achieve the lowering of the height of the drainage equipment such as the floor drain connected to the drainage inlet, and the lowering of the height of the interface connecting the drainage outlet to the drainage riser, thereby realizing the same-layer drainage pipe laying without lowering the plate, without raising the plate, or with less lowering and less raising of the plate, and the lowest point of the highest point of the drainage inlet is higher than the lowest point of the connection between the baffle and the second channel by 0mm-60mm. Therefore, the lowest point of the highest point of the drainage inlet at the lowest point (only) of the connection between the baffle and the second channel can prevent the drainage equipment connected to the drainage inlet from draining water from the drainage inlet, resulting in poor drainage, and the limit The drop distance can be reduced The overall height of the drainage device connected to the drainage inlet has achieved the purpose of not lowering the plate, not raising the plate, or less lowering and raising the plate; the bottom of the water seal baffle is lower than the lowest point of the connection between the drainage inlet and the main body, and lower than the lowest point of the connection between the baffle; the minimum height of the channel formed by the bottom of the water seal baffle and the inner wall of the bottom of the main body is greater than 10mm, and the water-passing cross-sectional area is greater than 1500mm2; there is a channel slope from the bottom of the drainage inlet and drainage outlet to the bottom of the inner wall of the main body; the outer contour of the bottom of the channel slope is smaller than the outer contour of the top of the channel slope; the height h from the bottom of the outer wall of the drainage outlet to the bottom of the main body is less than 100mm.
[0005] The integrated water seal used to change different-layer drainage to same-layer drainage is applied to the renovation of toilets, kitchens, and balconies in existing buildings or newly-built buildings that have used different-layer drainage. Since the thickness of the ground floor slab of traditional building structures is generally between 120mm and 140mm, and the total thickness of the decorative surface layers such as the leveling layer and the bonding layer above the structural ground floor slab is generally about 60mm-80mm, the total thickness of the structural ground floor slab plus the decorative surface layer is between 180mm and 220mm; when different-layer drainage is changed to same-layer drainage, the drainage holes on the original structural ground floor slab are first blocked, and then the decorative layer on the ground floor slab where the integrated water seal is to be installed is removed, and the structural ground floor slab is cut into an installation groove slightly larger than the bottom area of the body formed by the bottom of the channel slope of the body, and then the drainage inlet of the body is connected to the L-shaped floor drain (the total thickness of the L-shaped floor drain is about 30mm) and other wastewater drainage appliances above the bottom of the ground floor slab. The drainage outlet of the main body is connected to the drainage riser above the bottom of the ground floor slab, and then the sewage branch pipe connected to the toilet is separately connected to the drainage riser. The drainage inlet, drainage outlet and the bottom of the main body connected to the wastewater branch pipe are not exposed to the bottom surface of the structural ground floor slab, thereby completing the layout of changing the drainage of different floors of the drainage branch pipe to drainage on the same floor. During the installation process, since the height h from the bottom of the outer wall of the drainage outlet of the integrated water seal used to convert different-layer drainage to the same-layer drainage to the bottom of the body is less than 100mm, generally about 55mm, and since the lowest point of the drainage inlet is higher than the lowest point of the connection between the drainage outlet and the second channel between 0mm-60mm, and the bottom of the water seal baffle is lower than the lowest point of the connection between the drainage inlet and the body, lower than the lowest point of the connection between the baffle and the second channel, the lowest point of the connection between the drainage inlet and the body is higher than the lowest point of the connection between the baffle and the second channel between 0mm-60mm, and the minimum height of the channel formed by the bottom of the water seal baffle and the inner wall of the bottom of the body is greater than 15mm, therefore, when the drainage outlet is connected to the drainage riser above the bottom of the structural ground floor, the drainage inlet must also be connected to the floor drain and other wastewater horizontal branches above the bottom of the structural ground floor;When the height h from the bottom of the outer wall of the drainage outlet to the bottom of the body is about 50mm (in this case, the minimum height of the channel formed by the bottom of the water seal baffle and the inner wall of the bottom of the body is generally 25mm), the total thickness of the L-shaped floor drain connected to the drainage inlet is about 30mm, and the lowest point of the connection between the drainage inlet and the body is level with the lowest point of the connection between the baffle and the second channel, the total thickness of the bottom of the drainage outlet and the drainage horizontal branch pipe connected to the drainage vertical pipe to the floor drain connected to the drainage inlet is about 80mm. Therefore, as long as the decorative surface layer above the structural ground floor is removed and the drainage horizontal branch pipe is installed and backfilled For the decorative surface layer, there is no need to cut grooves in the structural ground floor slab, and the original different-layer drainage can be changed to the same-layer drainage without lifting the slab. There is no need to drill holes in the ground floor slab. The drainage branch pipe connecting the users on this floor does not need to enter the lower space, and does not affect the daily life of the owners of the lower floor. Of course, in order to increase the minimum height of the channel formed by the bottom of the water seal baffle and the inner wall of the bottom of the main body, to increase the width of the flow channel, or when the total thickness of the decorative surface layer is less than 80mm, the structural ground floor slab can be partially grooved to install the drainage branch pipes connected to the drainage inlet and drainage outlet, thereby realizing the original different-layer drainage. For buildings, under the condition that the ground floor does not have holes drilled and the daily life of the owners of the lower households is not affected, the ground floor is changed to the same-floor drainage without lifting the slab; and when the structural ground floor needs to be grooved, there is a channel slope from the bottom of the drainage outlet to the bottom of the inner wall of the main body; the bottom area of the main body surrounded by the bottom of the channel slope is less than 20000mm2, which can generally be set to about 110mm long * 100mm wide = 11000mm2, and the outer contour of the bottom of the channel slope is smaller than the outer contour of the top of the channel slope. Therefore, when the groove is deep, the small area of the channel slope and the bottom of the main body can avoid the structure of the ground floor. Steel mesh (the steel mesh of the ground floor is generally in the middle of the structural floor, and the length and width are generally 150mm*200mm) can avoid the structural damage of the ground floor caused by the installation of the integrated water seal, and can avoid the displacement of the drainage equipment (such as floor drains, etc.) and drainage cross-branch pipes connected to the drainage inlet of the integrated water seal due to the integrated water seal avoiding the structural steel mesh, creating conditions for prefabricating drainage cross-branch pipes, locating the drainage outlets of drainage equipment, realizing factory prefabrication, and rapid on-site installation. At the same time, the channel slope at the bottom of the drainage inlet and drainage outlet can guide drainage, accelerate discharge, and prevent clogging of emissions;Since the lowest point of the drainage inlet is higher than the lowest point of connection between the baffle and the second channel, when the sewage discharged from the drainage inlet is discharged from the drainage outlet, the height difference between the lowest point of connection and the lowest point of connection forms a drainage air replenishment space in the gap in the drainage inlet, which can prevent the drainage siphon from destroying the water seal and storing water, thereby improving the drainage safety. At the same time, the structure can form a fault-tolerant structure. When the drainage appliance connected to the drainage inlet has a water trap (such as a washbasin), the drainage air replenishment space can prevent the formation of a double water seal phenomenon in the same drainage section, prevent drainage blockage, and improve drainage smoothness. On this basis, the lowest point of connection between the drainage inlet and the first channel of the main body can be made within 60mm higher than the lowest point of connection between the drainage outlet and the second channel. Therefore, the height difference between the lowest point of connection and the lowest point of connection, combined with the ventilation structure of the first inspection port above the first channel, forms indirect drainage between the drainage of all wastewater horizontal branches connected to the drainage inlet and the drainage of the drainage riser connected to the drainage outlet, further preventing the formation of drainage siphon phenomenon and double water seal phenomenon (the double water seal phenomenon is mostly caused by a water seal on any interface in the drainage inlet plus The water seal structure of the present invention, such as the water trap under the washbasin when purchasing a bathroom cabinet, can greatly improve the smoothness and safety of drainage; the baffle is more than 15mm higher than the lowest point of the drainage outlet. When the distance between the drainage outlet of the integrated water seal and the drainage riser is close, the discharge water of the drainage riser can be prevented from flowing into the water seal water storage tank of the main body. During the epidemic, cross-infection of pathogens can be prevented, and drainage safety is improved; the water-passing cross-sectional area of the connecting channel formed by the baffle and the inner wall of the drainage outlet is greater than 1500mm2, and the bottom of the water seal baffle is connected to the bottom of the main body. The minimum height of the channel formed by the inner wall is greater than 10mm, and the water flow cross-sectional area is greater than 1500mm2, and the maximum width of each channel of the first channel and the second channel is not greater than 200mm, the minimum width is not less than 20mm, and the water flow cross-sectional area is not less than 1500mm2. Under the condition of ensuring the minimum width of the entire integrated water seal flow channel, the structure of the minimum water flow cross-sectional area is guaranteed, the flow channel guarantees the smallest object that can flow through, and the water flow cross-sectional area can ensure that the minimum drainage flow of the integrated water seal is not less than 0.8 liters per second, thereby improving the drainage patency. ;
[0006] The inner wall of the body is divided into a first channel and a second channel with the upper and side parts closed and the bottom connected by a water seal baffle. The maximum width of each channel is not more than 200mm, the minimum width is not less than 20mm, and the water flow cross-sectional area is not less than 1500mm2; the drainage inlet and the first inspection port are both located on the first channel; the structure in which the drainage outlet is located on the second channel can reduce the overall volume of the integrated water seal under the condition of ensuring the minimum width of the drainage flow channel, the minimum water flow cross-sectional area and the minimum water seal height, so that it is convenient to be installed in the pipeline well to occupy less building plane space and improve the utilization rate of the building plane space; and the bottom of the water seal baffle is lower than the lowest point of the connection between the drainage inlet and the body and the lowest point of the connection of the baffle. Therefore, the height of the water seal is formed by the difference between the bottom of the water seal baffle and the lowest connection point and the lowest connection point of the baffle. When water is stored at the bottom of the closed body, harmful gases in the drainage riser can be prevented from entering the drainage device connected to the drainage inlet and being discharged into the room to affect human health.
[0007] The integrated water seal for converting different-floor drainage into same-floor drainage of a building described in the present invention has multiple drainage inlets on the first channel, and a drainage reverse valve is provided on the inner wall of one of the drainage inlets, the drainage reverse valve comprising a valve body and a valve cover; the valve body is an inclined cylinder penetrating from front to back; the valve body has a valve face and a connecting rod hole facing the first channel, the connecting rod is on the upper part of the valve face, and the valve face is an inclined surface with a front-to-back width greater than the front-to-back width of the upper part; the valve cover covers the valve face, and the valve cover has a connecting rod head, which is sleeved in the connecting rod hole of the valve face; a filter grid is provided at the front end of the drainage inlet where the drainage reverse valve is placed.
[0008] The integrated water seal used to convert different-floor drainage into same-floor drainage in a building, when a drainage reverse valve and a filter grid are installed in a drainage inlet, the ground floor can prevent sudden leakage accidents in the water supply and drainage pipes and valves, and can be discharged from the reverse valve, and the valve face of the drainage reverse valve is an inclined surface with a lower front-to-back width greater than an upper front-to-back width; the valve cover is covered on the valve face, and a connecting rod head is provided on the valve cover, and the connecting rod head is sleeved in the connecting rod hole on the valve face, thereby, the valve cover can be freely covered on the valve face under the action of gravity, and the valve cover and the valve face will not be unable to be closed due to the installation slope of the integrated water seal and the connected drainage cross branch pipe. At the same time, the drainage reverse valve can prevent the drainage in the drainage inlet from flowing out of the drainage reverse valve.
[0009] The integrated water seal for converting different-floor drainage into same-floor drainage in a building described in the present invention has a lowest connection point between the drainage inlet and the first channel that is not lower than the lowest connection point between the drainage outlet and the second channel, and a height from the bottom of the inner wall of the drainage inlet to the bottom of the outer wall of the main body that is less than 120 mm.
[0010] The integrated water seal for converting different-floor drainage into same-floor drainage of a building described in the present invention has a second inspection port on the top of the second channel, and an inspection cover plate on the second inspection port. The inspection cover plate and the inspection port are detachably sealed and connected. The second inspection port is at the top of the second channel. Therefore, after the integrated water seal is installed, it is convenient to clear blockage and inspect from the top of the second channel. The inspection cover plate and the inspection port are detachably sealed and connected. They are usually sealed to ensure that harmful gases in the vertical pipe must pass through the water seal to enter the room, thereby ensuring drainage safety. During inspection and clearing, the cover plate is separated.
[0011] The first inspection port described in the present invention is provided with a cover plate, which is connected to the first inspection port in a non-sealed manner, thereby allowing air to be replenished in the drainage branch pipe connected to the integrated water seal to prevent siphoning and double water seal phenomena. The bottom of the main body is flat, which is convenient for placement on the ground and installation by one person.
[0012] The integrated water seal for converting different-floor drainage into same-floor drainage of a building described in the present invention is characterized in that the front-to-back length of the main body does not exceed 250 mm, and the left-right width does not exceed 130 mm. Thus, the integrated water seal reduces its volume, occupies little plane space of the building after connecting the drainage lateral branch pipe, and can be installed as a whole in the integrated pipe well.
