Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline descaling, in particular to a descaling agent filling device. Background Art
[0002] There are many ways to descale pipes, among which using a filling pipe to add descaling agent is a common method. The existing filling pipe is simple and easy to use, and only needs to add the descaling agent into the pipe, which is a relatively mature technology. However, in the actual filling process, due to the excessive length of the pipe and the large amount of dirt attached to the pipe, the filling of the descaling agent will be hindered. At the same time, after filling, the descaling agent will not flow smoothly into the pipe, thus affecting the progress of descaling. Utility Model Content
[0003] In view of the deficiencies of the prior art, the utility model provides a descaling agent filling device, which solves the problem that the existing pipeline is too long and a lot of dirt attached to the pipeline hinders the descaling agent filling.
[0004] To achieve the above purpose, the utility model is implemented through the following technical scheme. The utility model provides a descaling agent filling device, including a tube body and a pressure gas cylinder, a filling head is installed at one end of the tube body, a filling tube is movably inserted in the filling head, a plurality of liquid outlet holes and a plurality of liquid inlet holes are respectively opened on the side walls at both ends of the filling tube, a conical top and a piston are respectively fixedly installed at both ends of the filling tube, the piston slides in the tube body, a connecting pipe is installed at the outlet end of the pressure gas cylinder, one end of the connecting pipe is screwed to the inside of the other end of the tube body, and a sealing mechanism is provided in the filling head.
[0005] Furthermore, the sealing mechanism includes three grooves opened in the inner wall of the filling head, and circular rings are respectively installed in the three grooves. The filling pipe slides in the three circular rings. A fixed block is provided on the inner wall of the filling head, and a sliding groove is opened on the outer wall of the filling pipe. The sliding groove is slidably installed on the outside of the fixed block.
[0006] Furthermore, a pressure relief valve, a pressure gauge and a valve are installed on the connecting pipe.
[0007] Furthermore, a second piston is slidably mounted in the tube body, and a push rod is connected between the second piston and the piston.
[0008] Beneficial Effects
[0009] The utility model provides a descaling agent filling device, which has the following beneficial effects:
[0010] 1. A filling pipe is provided inside the pipe body. The filling pipe is provided with a liquid outlet hole and a liquid inlet hole. The valve is opened to add the gas in the pressure gas cylinder into the pipe body through the connecting pipe. With the addition of gas, the second piston and the piston will be pushed to move toward the filling head side of the pipe body. The descaling agent in the pipe body will enter the filling pipe through the liquid inlet hole and finally be sprayed out from the liquid outlet hole. At the same time, the filling pipe extends from the pipe body while spraying the descaling agent, so as to facilitate the descaling agent to be directly delivered into the pipe.
[0011] 2. A conical top is provided at the front end of the filling pipe. When the filling pipe moves into the pipeline, the conical top destroys the dirt, making it easier to quickly deliver the descaling agent to deeper parts of the pipeline. The gas in the pressure cylinder pushes the second piston and the piston in the pipe body. Since the gas has certain compressibility and buffering properties, when the conical top is suddenly blocked by large dirt, the filling pipe will move toward the pipe body to avoid forced hard contact with the dirt, which has a certain protective effect on the conical top and the filling pipe.

DETAILED DESCRIPTION
[0015] 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.
[0016] See also Figure 1-2The utility model provides a technical solution: a descaling agent filling device, including a tube body 6 and a pressure gas cylinder 14, a filling head 4 is installed at one end of the tube body 6, a filling pipe 3 is movably inserted in the filling head 4, a plurality of liquid outlet holes 2 and a plurality of liquid inlet holes 8 are respectively opened on the side walls at both ends of the filling pipe 3, a conical head 1 and a piston 9 are respectively fixedly installed at both ends of the filling pipe 3, the piston 9 slides in the tube body 6, a connecting pipe 11 is installed at the outlet end of the pressure gas cylinder 14, one end of the connecting pipe 11 is screwed to the inside of the other end of the tube body 6, and a sealing mechanism is provided in the filling head 4; a descaling agent is provided in the tube body 6 between the filling head 4 and the piston 9, when the piston 9 and the filling pipe 3 move to the left together, the descaling agent will be pressurized, so that it enters the filling pipe 3 along the liquid inlet hole 8 and finally sprays out from the liquid outlet hole 2; as the second piston 10 and the gas in the tube body 6 increase, the filling pipe 3 will spray the descaling agent while moving to the left.
[0017] Furthermore, the sealing mechanism includes three grooves formed in the inner wall of the filling head 4, in which circular rings 5 are respectively installed, and the filling pipe 3 slides in the three circular rings 5. A fixed block 7 is provided on the inner wall of the filling head 4, and a slide groove 15 is formed on the outer wall of the filling pipe 3, and the slide groove 15 is slidably installed on the outside of the fixed block 7.
[0018] Furthermore, a pressure relief valve 16, a pressure gauge 12 and a valve 13 are installed on the connecting pipe 11; the pressure gauge 12 is used to observe the air pressure in the pipe body 6. When the pressure gauge 12 decreases significantly, it indicates that there is a gas leakage. When the pressure gauge 12 increases significantly, it indicates that the conical head 1 and the filling pipe 3 are blocked and difficult to fill. It is necessary to pull out the pipe body 6 to check the situation in the pipeline.
[0019] Furthermore, a second piston 10 is slidably installed in the tube body 6 , and a push rod is connected between the second piston 10 and the piston 9 .

During the movement of the filling pipe 3 into the pipeline, the conical head 1 will destroy the dirt, which is convenient for the filling of the descaling agent. When the filling is completed, close the valve 13, then open the pressure relief valve 16, unload the excess gas, and then pull out the tube body 6.
