Description

Technical Field

[0001] The utility model relates to the technical field of expansion water tanks, in particular to an internal water level detection device for an expansion water tank. Background Art

[0002] The expansion tank is an important component in the HVAC system. It accommodates the expansion of the system water in the heating system, and also plays a role in maintaining pressure and replenishing water for the system. The expansion tank is generally made of steel plates and is usually round or rectangular. Due to the thermal expansion and contraction of the water in the heating system, when the hot water is heated, the water volume in the system increases. When there is no place to accommodate this part of the water expansion, the water pressure in the heating system increases, which will affect normal operation.

[0003] The expansion water tank is an important component in the hot water heating system and the central air-conditioning water system. Its function is to accommodate and compensate for the expansion and contraction of the water in the system. The expansion water tank can also stabilize the system pressure and remove the air released by the water during the heating process. In order to monitor the amount of water stored inside the expansion water tank, a scale is usually opened on the inner wall of the expansion water tank, or a floating scale is provided inside the expansion water tank. When the staff checks the water inside the expansion water tank, the staff needs to open the vertical expansion water tank for inspection, which is rather troublesome. For this reason, we provide an internal water level detection device for an expansion water tank to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide an internal water level detection device for an expansion water tank, which can check the water inside the water tank without opening the expansion water tank.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an internal water level detection device for an expansion water tank, comprising a water tank body, a pushing mechanism is provided inside the water tank body, the pushing mechanism comprises two vertical rods fixed to the inner bottom wall of the water tank body, the outer surface of the vertical rods is slidably connected with a slip ring, the outer surface of the slip ring is fixedly connected with a liquid level plate, one side of the liquid level plate is fixedly connected with a floating plate, the top of the vertical rods is fixedly connected with a sealing bin, two sleeves are provided inside the sealing bin, each sleeve is provided with a pushing plug inside, the bottom end of the pushing plug is fixedly connected with a sleeve rod, the bottom end of the sleeve rod passes through the sleeve and the sealing bin in sequence and is fixedly connected to the upper surface of the liquid level plate, and the upper surface of the water tank body is provided with a detection mechanism.

[0006] Furthermore, the detection mechanism includes a vertical plate that is beneficial to the upper surface of the water tank body, and the left side of the vertical plate is fixedly connected with a push cylinder, and the two sleeves are connected with the push cylinder through a bent pipe. A push rod is provided inside the push cylinder, and a sliding ring is slidably connected to the outer surface of the push cylinder, and the sliding ring is connected to the top of the push rod through a connecting rod. The left side of the vertical plate is fixedly connected with a mounting plate, and a through groove is provided on the front of the mounting plate. A benchmark rod is fixedly connected to the outer surface of the sliding ring, and one end of the benchmark rod is slidably connected to the inner wall of the through groove, and a scale is fixedly connected to the front of the mounting plate. The air inside the sleeve is pressed into the interior of the push cylinder through the bent pipe, and the air pressure inside the push cylinder is used to push the push rod. The push rod drives the sliding ring to move through the connecting rod, and the sliding ring drives the benchmark rod to move inside the through groove. The benchmark rod and the scale are compared to obtain the water storage amount inside the water tank body.

[0007] Furthermore, two sealing slip rings are fixedly embedded on the bottom surface of the sealing bin, the bottom ends of the two sleeve rods respectively penetrate the two sealing slip rings and extend to the outside of the sealing bin, and the sleeve rod is slidably connected to the inner wall of the sealing slip ring. The sealing slip ring can effectively reduce the friction between the sleeve rod and the sealing bin to avoid wear on the outer surface of the sleeve rod, and at the same time effectively seal the connection between the sleeve rod and the sealing bin to prevent water from entering the interior of the sealing bin and causing water to enter the interior of the sealing bin.

[0008] Furthermore, a fixing plate is fixedly connected to the outer surface of the sleeve, and the bottom surface of the fixing plate is fixedly connected to the inner bottom wall of the sealing chamber. The fixing plate can fix the two sleeves, thereby improving the stability of the sleeves during use and preventing the sleeves from swinging and affecting the normal use of the pushing mechanism.

[0009] Furthermore, a stabilizing plate is fixedly connected to the outer surface of the push cylinder, and the right side of the stabilizing plate is fixedly connected to the left side of the vertical plate, which can fix the push cylinder and the vertical plate, further fix the push cylinder, improve the stability of the push cylinder during use, and avoid shaking of the push cylinder during use.

[0010] Furthermore, an observation window is provided on the front of the water tank body, and the observation window is a glass observation window, which is convenient for staff to directly observe the water level inside the water tank body through the observation window, and compare the observed water level with the position displayed on the installation plate, thereby avoiding deviations in detection by the detection mechanism.

[0012] Compared with the prior art, the internal water level detection device for the expansion water tank has the following beneficial effects:

[0013] 1. The utility model uses the buoyancy generated by the water body inside the water tank body to push the floating plate to drive the liquid level plate to move upward. The liquid level plate pushes the sealing plug through the sleeve rod to push the air inside the sleeve. The air enters the inside of the push tube through the curved pipe. The air inside the sleeve is pressed into the inside of the push tube through the curved pipe. The air pressure inside the push tube is used to push the push rod. The push rod drives the sliding ring to move through the connecting rod. The sliding ring drives the benchmark rod to move inside the through groove. The benchmark rod is compared with the scale to obtain the water storage amount inside the water tank body. Therefore, the water level inside the water tank body can be observed without opening the water tank body.
