Abstract
Description
Technical Field
[0001] The utility model belongs to the field of water inlet bottom pipes, in particular to a water inlet bottom pipe with a check valve. Background Art
[0002] The water inlet bottom pipe is used for water inlet to the pump station. The check valve refers to a valve whose opening and closing parts are circular valve discs and which rely on its own weight and medium pressure to produce movement to block the backflow of the medium. When water needs to be passed into the tank body through the bottom of the tank body, as the water in the tank body increases, the pressure at the bottom of the tank body becomes greater and greater, and the pressure that needs to be overcome to pump water into the tank body becomes greater and greater, making it difficult to pump water into the tank body. Therefore, we designed a water inlet bottom pipe with a check valve. Utility Model Content
[0003] The utility model provides a water inlet bottom pipe with a check valve, which is used to solve the defects in the prior art.
[0004] The utility model is realized through the following technical solutions:
[0005] A water inlet bottom pipe with a check valve comprises a tank body, a water inlet pipe and a drain pipe are connected and installed on the tank body, an air outlet pipe is connected and installed on the top of the tank body, valves are connected and installed on the water inlet pipe, the drain pipe and the air outlet pipe respectively, and the valve on the water inlet pipe is a check valve, which is characterized in that one end of the water inlet pipe located in the tank body is connected and installed on the water outlet pipe through a spring tube, a floating plate is fixedly installed on the periphery of the water outlet pipe, and the top of the water outlet pipe is always higher than the top of the floating plate.
[0006] In the water inlet bottom pipe with a check valve as described above, a plurality of supporting legs are fixedly installed at the bottom of the tank body.
[0007] In the water inlet bottom pipe with a check valve as described above, a plurality of through holes are provided on the floating plate, and slide bars are slidably installed in the through holes, and the slide bars are fixedly installed on the tank body.

[0010] In the water inlet bottom pipe with a check valve as described above, a sewage outlet is provided at the bottom of the tank body, and an internal thread cover is installed in cooperation with the inner thread thread of the sewage outlet.
[0011] The advantages of the utility model are: the utility model has a simple structure and an ingenious design. A floating plate is arranged in the tank body. Under the buoyancy of water, the floating plate is always above the water surface, and the top of the water outlet pipe is always higher than the top of the floating plate. Therefore, the water outlet will not be affected by the water pressure in the tank body, which solves the problem of overcoming the water pressure when pumping water from the bottom of the tank body into the tank body. The utility model can meet market demand and is suitable for promotion. When the utility model is used, the valves on the water inlet pipe and the air outlet pipe are opened, and water is pumped into the tank body through the water inlet pipe, the spring tube and the water outlet pipe in sequence. The water in the tank body gives the floating plate an upward buoyancy, so that the floating plate always floats on the water surface, and as the water level in the tank body rises, the floating plate moves upward, and the spring tube is stretched. Since the water outlet pipe is fixedly installed on the floating plate and the water outlet pipe is always higher than the floating plate, the water outlet pipe will not be affected by the pressure of the water in the tank body when discharging water, so there is no need for increasing force to pump water into the tank body. As the liquid level in the tank body rises, the air in the tank body is discharged from the tank body through the air outlet pipe; when it is not necessary to pump water into the tank body, the valves on the water inlet pipe and the air outlet pipe are closed; when it is necessary to discharge the water in the tank body, the valve on the drain pipe is opened to allow the water in the tank body to be discharged from the tank body through the drain pipe.

DETAILED DESCRIPTION
[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.
[0016] A water inlet bottom pipe with a check valve, such as Figure 1As shown, it includes a tank body 1, on which a water inlet pipe 2 and a drain pipe 3 are connected and installed, the bottom of the tank body 1 is connected and installed with the water inlet pipe 2, one side of the tank body 1 is connected and installed with the drain pipe 3, and the top of the tank body 1 is connected and installed with an air outlet pipe 4. The water inlet pipe 2, the drain pipe 3 and the air outlet pipe 4 are connected and installed with valves 5 respectively, and the valve 5 on the water inlet pipe 2 is a check valve, which is characterized in that: one end of the water inlet pipe 2 located in the tank body 1 is connected and installed with a water outlet pipe 7 through a spring tube 6, one end of the spring tube 6 is connected and connected with the upper end of the water inlet pipe 2, and the other end of the spring tube 6 is connected and connected with the lower end of the water outlet pipe 7, a floating plate 8 is fixedly installed on the periphery of the water outlet pipe 7, a reserved hole is provided on the floating plate 8, the water outlet pipe 7 is fixedly installed in the reserved hole, and the top of the water outlet pipe 7 is always higher than the top of the floating plate 8. The utility model has a simple structure and ingenious design. A floating plate 8 is provided in the tank body 1. Under the buoyancy of water, the floating plate 8 is always higher than the water surface, and the top of the water outlet pipe 7 is always higher than the top of the floating plate 8. Therefore, the water outlet will not be affected by the water pressure in the tank body 1, which solves the problem of overcoming the water pressure when pumping water from the bottom of the tank body 1 into the tank body 1. The utility model can meet market demand and is suitable for promotion. When the utility model is used, the valves 5 on the water inlet pipe 2 and the air outlet pipe 4 are opened, and water is pumped into the tank body 1 through the water inlet pipe 2, the spring tube 6 and the water outlet pipe 7 in sequence. The water in the tank body 1 gives the floating plate 8 an upward buoyancy, so that the floating plate 8 always floats on the water surface, and as the water surface in the tank body 1 rises, the floating plate 8 moves upward, and the spring tube 6 is stretched. Since the water outlet pipe 7 is fixedly installed on the floating plate 8 and the water outlet pipe 7 is always higher than the floating plate 8, when the water outlet pipe 7 discharges water, it will not be affected by the pressure of the water in the tank body 1, so there is no need for more and more force to pump water into the tank body 1. As the liquid level in the tank body 1 rises, the air in the tank body 1 is discharged from the tank body 1 through the air outlet pipe 4; when it is not necessary to pump water into the tank body 1, the valves 5 on the water inlet pipe 2 and the air outlet pipe 4 are closed; when it is necessary to discharge the water in the tank body 1, the valve 5 on the drain pipe 3 is opened, so that the water in the tank body 1 is discharged from the tank body 1 through the drain pipe 3.
[0017] Specifically, as shown in the figure, the bottom of the tank body 1 in this embodiment is fixedly installed with a plurality of support legs 20. The support legs 20 facilitate the tank body 1 to be supported on the ground, and prevent the tank body 1 from being directly placed on the ground and affecting the water supply from the water inlet pipe 2 to the tank body 1.
[0018] Specifically, as shown in the figure, the floating plate 8 of this embodiment is provided with a plurality of through holes 30, and slide bars 31 are slidably installed in the through holes 30, respectively, and the slide bars 31 are fixedly installed on the tank body 1. The slide bars 31 can limit the floating plate 8 so that the floating plate 8 remains horizontal, and prevent the floating plate 8 from tipping over and causing the water in the tank body 1 to flow back through the water outlet pipe 7.
[0019] Further, as shown in the figure, the through hole 30 in this embodiment is connected to the corresponding slide bar 31 through a linear bearing 40, and the linear bearings 40 are fixedly mounted on the inner periphery of the through hole 30, and the balls in the linear bearings 40 are rollingly connected to the outer periphery of the corresponding slide bar 31. The linear bearings 40 can transform the sliding connection between the inner periphery of the through hole 30 and the outer periphery of the corresponding slide bar 31 into a rolling connection, thereby reducing the friction between the through hole 30 and the corresponding slide bar 31 when the floating plate 8 moves up and down.
[0020] Further, as shown in the figure, scraper rings 50 are respectively provided on the upper and lower sides of the floating plate 8 of this embodiment. The scraper rings 50 are circular rings with inclined surfaces at the top and bottom, respectively. The inner circumference of the top of the circular ring is lower than the outer circumference, and the inner circumference of the bottom of the circular ring is higher than the outer circumference. The scraper rings 50 are respectively coaxially arranged with the tank body 1. The scraper rings 50 are respectively fixedly installed on the floating plate 8 through connecting rods, and the tips of the outer circumferences of the scraper rings 50 are respectively slidably connected with the inner circumference of the tank body 1. The scraper rings 50 can scrape off the impurities attached to the tank body 1 to ensure the cleanliness of the inner wall of the tank body 1; the two scraper rings 50 distributed above and below can ensure the cleaning of the inner wall of the tank body 1 without dead angles.
[0021] Furthermore, as shown in the figure, the bottom of the tank body 1 of this embodiment is provided with a drain port 60, and the inner circumferential thread of the drain port 60 is matched with an inner thread cover 61. Impurities scraped off on the inner wall of the tank body 1 by the scraper ring 50 fall into the bottom of the tank body 1. When there is no water in the tank body 1, the inner thread cover 61 is removed from the inner circumference of the drain port 60, and then the impurities are removed through the drain port 60, and then the inner thread cover 61 is screwed on the inner circumference of the drain port 60.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
