Description

Technical Field

[0001] The utility model relates to a pipeline water discharge device, belonging to the field of municipal heating. Background Art

[0002] Radiators are a common heating equipment that transfers hot water or steam to metal sheets to emit heat and provide a warm indoor environment. Radiators need to be connected to municipal heating pipes. When the heat conversion efficiency of the radiator becomes low, the drain valve on the radiator pipe needs to be opened to discharge the dirt in the radiator pipe. Because there is residual pressure in the radiator pipe, when the drain valve is opened, the hot water in the radiator pipe will splash out of the drain valve at will under the action of the residual pressure, causing pollution to the walls around the radiator, etc. Therefore, it is necessary to design a pipe drain device to prevent the hot water in the radiator pipe from splashing at will. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a pipeline water drain device to solve the problems raised in the above-mentioned background technology. The utility model prevents hot water in the radiator pipeline from splashing randomly.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a pipeline drainage device, including a drainage valve for installation on a radiator pipeline, a pipe joint is installed at one end of the drainage valve, and the end of the pipe joint away from the drainage valve is connected to a temporary storage tube, a tube cover is installed at the end of the temporary storage tube away from the pipe joint, a threaded rod is threadedly connected to the middle position of one side of the tube cover, a connecting rod is connected and fixed to the end of the threaded rod in the temporary storage tube, a conical head for sealing the pipe joint is connected and fixed to the end of the connecting rod away from the threaded rod, a handle is installed at the end of the threaded rod away from the connecting rod, and a drain valve is installed at the lower position of the outer surface of the temporary storage tube.

[0005] Furthermore, both ends of the drain valve are connected and fixed with a first connecting ring with a hole, the end of the pipe joint away from the temporary storage tube is connected and fixed with a second connecting ring with a hole, and the first connecting ring is connected and fixed with the second connecting ring by means of a plurality of screws and nuts.

[0006] Furthermore, a support ring with a hole is sleeved on the pipe joint and is connected and fixed to the pipe joint. The support ring is arranged between the temporary storage tube and the second connecting ring. There is a gap between the support ring and the second connecting ring. One end of the screw passes through the first connecting ring, the second connecting ring and the support ring in sequence, and the nut is arranged between the support ring and the temporary storage tube.

[0007] Furthermore, an arc-shaped opening is provided on the outer surface of the temporary storage tube, and an arc-shaped transparent strip is embedded in the arc-shaped opening.

[0008] Furthermore, a straight cylinder is installed at the middle position of one side of the cylinder cover, a positioning plate is connected and fixed at the middle position inside the straight cylinder, a threaded hole is opened at the middle position of one side of the positioning plate, the threaded rod is threadedly connected in the threaded hole, an end of the threaded rod close to the handle is sleeved with a first rubber ring adhered to the threaded rod, the first rubber ring is slidably installed in the straight cylinder, an end of the connecting rod close to the threaded rod is sleeved with a second rubber ring adhered to the connecting rod, the second rubber ring is slidably installed in the straight cylinder, and the distance between the first rubber ring and the second rubber ring is half the length of the straight cylinder.

[0009] Furthermore, a circular opening is provided in the middle of one side of the cylinder cover, and one end of the straight cylinder is connected and fixed in the circular opening.

[0010] Beneficial effects of the utility model:

[0011] 1. After opening the drain valve, the hot water in the radiator pipe first flows into the space formed by the temporary storage cylinder and the cylinder cover, thereby limiting the splashing range of the hot water discharged from the drain valve. After opening the drain valve, the hot water in the temporary storage cylinder flows into the collection container through the drain valve, preventing the hot water in the radiator pipe from splashing at will.

[0012] 2. After opening the drain valve, use the handle to rotate the threaded rod, the threaded rod drives the connecting rod to move, and the connecting rod drives the conical head to move, so that the gap between the conical head and the inner wall of the pipe joint becomes larger or smaller, thereby controlling the amount of hot water flowing into the temporary storage cylinder per unit time.

[0013] 3. The threaded rod is threaded into the threaded hole, and the positioning plate is fixed in the middle of the straight tube. At this time, the first rubber ring and the second rubber ring are both slidably installed in the straight tube. On the one hand, small debris is prevented from entering the threaded hole at will. On the other hand, the effective connection part between the threaded rod and the positioning plate is in a closed environment to prevent the effective connection part between the threaded rod and the positioning plate from being damp and rusted.

[0014] 4. When connecting the drain valve and the pipe joint by means of screws and nuts, one end of the screw is passed through the first connecting ring, the second connecting ring and the support ring in sequence, and then the nut is screwed on. At this time, there is a gap between the nut and the second connecting ring. When the nut and the screw are difficult to separate due to rust, the space between the support ring and the second connecting ring can be used to cut off the screw, thereby reducing the difficulty of disassembling and assembling the drain valve and the temporary storage tube.
