Description

Technical Field

[0001] This invention relates to the field of rust prevention treatment, and in particular to a rust prevention treatment device for water supply and drainage equipment. Background Technology

[0002] Water supply and drainage equipment plays a vital role in modern society, widely used in urban water supply, sewage treatment, agricultural irrigation, and many other fields. However, these devices are constantly exposed to humid environments, making them highly susceptible to corrosion. This corrosion can lead to decreased equipment performance, shortened lifespan, and even equipment failure, resulting in serious economic losses and safety hazards.

[0003] Traditional rust prevention methods primarily involve manually applying rust-preventive paint or paste. While this method can prevent rust, the following technical problems exist in the manual application of paste: 1. Insufficient space in mechanical equipment prevents manual application to the back of the bolts; 2. Incomplete or insufficient application of paste; 3. Inability to apply paste to bolt joints; 4. Inability to assess the effectiveness of the paste application. These factors contribute to the ineffectiveness of rust prevention. Summary of the Invention

[0004] The purpose of this invention is to provide a rust prevention treatment device for water supply and drainage equipment. It addresses the technical problem that existing water supply and drainage equipment often suffers from inadequate grease application, failing to effectively prevent rust.

[0005] A rust prevention treatment device for water supply and drainage equipment includes a first sleeve and a second sleeve with one end threadedly connected, and the distance between the other ends of the first sleeve and the second sleeve can be adjusted by adjusting the length of the threaded connection.

[0006] The first sleeve and / or the second sleeve are provided with grease inlets on their outer walls. The grease inlets are connected to the grease outlets of the extrusion filling assembly. When applying grease, the other ends of the first sleeve and the second sleeve are respectively fitted onto the outside of the bolts on both sides of the water supply and drainage equipment.

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] Example:

[0034] like Figure 1 and Figure 2 The rust prevention device for water supply and drainage equipment shown includes a first sleeve 1 and a second sleeve 2 with one end threadedly connected, and the distance between the other ends of the first sleeve 1 and the second sleeve 2 can be adjusted by adjusting the length of the threaded connection.

[0035] The first sleeve 1 and / or the second sleeve 2 are provided with an oil inlet 3 on their outer walls. The oil inlet 3 is connected to the oil outlet of the extrusion filling component. When applying the oil, the other ends of the first sleeve 1 and the second sleeve 2 are respectively fitted onto the outside of the bolts 4 on both sides of the water supply and drainage equipment.

[0036] In this embodiment, both the first sleeve 1 and the second sleeve 2 are made of transparent material, which is inexpensive and allows direct observation of the filling progress and effect of the ointment. In this embodiment, as... Figure 1 The water supply and drainage equipment is a water supply and drainage pipe 5 (commonly used as a connecting pipe in water supply and drainage systems) connected by a flange, and both sides of it are connected to other pipelines by screws and bolts.

[0037] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, an external thread 11 is provided on the outer wall of one end of the first sleeve 1, and an internal thread 12 is provided on the inner wall of one end of the second sleeve 2.

[0038] In this embodiment, the total length of the first sleeve 1 and the second sleeve 2 is adjusted by adjusting the length of the threaded connection, so that the other ends of the first sleeve 1 and the second sleeve 2 respectively abut against the inner sidewalls of the flanges at both ends of the water supply and drainage pipe 5. This provides high stability and facilitates the application of sealant.

[0039] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the first sleeve 1 includes two first semi-annular plates 101 that are joined together;

[0040] The second sleeve 2 includes two semi-annular plates 201 that are joined together. The joint surfaces of the first semi-annular plate 101 and the second semi-annular plate 201 are provided with mold snaps 13.

[0041] In this embodiment, because the screw protrusion length inside the water supply and drainage pipe 5 is relatively long, the first sleeve 1 and the second sleeve cannot be fitted together. Therefore, the first sleeve 1 and the second sleeve 2 are both set as two semi-annular plates. During installation, the two first semi-annular plates 101 are first fitted onto the outside of the screw and bolt 3 respectively and then connected by the mold snap fastener 13. Then, the two second semi-annular plates 201 are snapped onto the outside of the first sleeve 1 and connected by the mold snap fastener 13 (external thread 11 and internal thread 12 are engaged). The length of the connecting thread is then adjusted so that it abuts against the inner end face of the flange plates on both sides. In this embodiment, the external threads 11 are distributed on the two first semi-annular plates 101 respectively, and the internal threads 12 are distributed on the second semi-annular plates 201 respectively. During processing, the semi-annular plates are first assembled and then processed simultaneously to ensure the consistency of the threads.

[0042] As one embodiment of this application, such as Figure 7 As shown, the mold snap fastener 13 includes an L-shaped groove 131 on one side of the splicing surface of the semi-annular plate (first semi-annular plate 101 or second semi-annular plate 201) and an L-shaped lug 132 on the other side of the semi-annular plate. When splicing, the L-shaped lug 132 of one semi-annular plate is placed into the opening of the L-shaped groove 131 of the other semi-annular plate, and the L-shaped lug 132 of one semi-annular plate is pushed into the L-shaped groove 131 of the other semi-annular plate to realize the connection of the two semi-annular plates.

[0043] As an embodiment of this application, in order to reduce the contact between the other end of the first sleeve 1 and the second sleeve 2 and the outer end face of the bolt 3 during the sleeve installation process, which would result in incomplete application of grease, 5mm burrs can be provided on the inner wall of the other end of the first sleeve 1 and the second sleeve 2 to reduce the contact area between the bolt 3 and the inner wall of the first sleeve 1 and the second sleeve 2.

[0044] like Figure 2 , Figure 4 and Figure 5 As shown, the other ends of the first sleeve 1 and the second sleeve 2 are each equipped with a flexible sealing ring 6 for sealing with the end face of the water supply and drainage equipment.

[0045] In this embodiment, as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the flexible sealing ring 6 includes two semi-annular sealing rings 601 that are joined together;

[0046] Two semi-annular sealing rings 601 are respectively installed at the other end of the two first semi-annular plates 101 or the two second semi-annular plates 201.

[0047] In this embodiment, to improve the sealing performance between the first sleeve 1 and the second sleeve 2 and the flange end face of the water supply and drainage pipe 5, flexible sealing rings 6 are provided at the other ends of both the first sleeve 1 and the second sleeve 2. To adapt to the semi-annular structure of the first sleeve 1 and the second sleeve 2, the flexible sealing rings 6 are also configured as two semi-annular sealing rings 601. In this embodiment, the semi-annular sealing rings 601 are made of rubber or flexible plastic.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the extrusion filling assembly includes a piston cylinder 7;

[0049] A compression piston 8 is slidably disposed inside the piston cylinder 7. A sealing ring 9 is fitted on the compression piston 8 to slidably seal against the inner wall of the piston cylinder 7. An oil outlet 14 is provided at the bottom of the piston cylinder 7. The oil outlet 14 is connected to the oil inlet 3 through a flexible tube 10.

[0050] In this embodiment, the grease is stored in the piston cylinder 7. When the two ends of the first sleeve 1 and the second sleeve 2 respectively come into contact with the flanges at both ends of the water supply and drainage pipe 5, the extrusion piston 8 is pushed to allow the grease to enter the first sleeve 1 and the second sleeve 2 through the grease outlet 14, the flexible pipe 10 and the grease inlet 3. When the first sleeve 1 and the second sleeve 2 are completely filled with grease, the application is completed, the oiling is stopped, and the first sleeve 1 and the second sleeve 2 are disassembled.

[0051] In this embodiment, the grease inlet 3 is located on the outer wall of the first sleeve 1, which connects the inner and outer walls of the first sleeve 1, and the inner hole of the first sleeve 1 is connected to the inner hole of the second sleeve 2.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
