Description

Technical Field

[0001] The utility model relates to the technical field related to a compression valve group, and more particularly to a compression valve used on ship rust removal equipment. Background Art

[0002] Ship rust removal refers to a series of surface treatments performed on a ship before painting to remove rust, old paint, scale, oil stains, and other substances, ensuring the coating achieves its intended protective effect. This process is crucial for extending the ship's service life, preventing seawater erosion, and ensuring coating adhesion and corrosion resistance. The primary purpose of ship rust removal is to ensure that the coating can fully perform its protective and decorative functions. By removing rust and dirt from the hull surface, the paint's adhesion to the hull is enhanced, thereby improving the coating's corrosion resistance and service life. Furthermore, effective surface treatment reduces seawater erosion on the hull, ensuring the ship's safety and stability.

[0003] Modern ship rust removal equipment mainly uses robotic technology and ultra-high-pressure water jet technology. Among them, ultra-high-pressure water jet rust removal is an advanced method that uses ultra-high-pressure water flow to treat hull rust. It is not only environmentally friendly but also highly efficient. This technology replaces traditional manual rust removal and improves operational efficiency and safety. Ultra-high-pressure water jet rust removal requires the water jet equipment to operate at a constant pressure to ensure efficient and stable rust removal operations. This requires the pre-pressure valve group to precisely control the water flow within the preset pressure range, thereby avoiding uneven rust removal quality or decreased efficiency due to pressure fluctuations. Therefore, we have proposed a clamping valve for ship rust removal equipment to solve the above-mentioned problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Example:

[0031] See also Figure 1-5 A compression valve for ship rust removal equipment includes a valve group housing 6, on which a balancing valve 1, a proportional relief valve 2, an electromagnetic ball valve 3 and a shuttle valve 4 are installed;

[0032] The balancing valve 1 is provided with an access port, and there are two access ports, one of which is used for liquid inlet and the other is used for liquid outlet;

[0033] A shuttle valve 4 is installed on both side walls and the front of the valve group housing 6, and the three shuttle valves 4 are M1, M2 and M3 respectively;

[0034] An electromagnetic coil 5 is installed inside the electromagnetic ball valve 3;

[0035] The output end of the shuttle valve 4 is conductively connected to the input end of the electromagnetic ball valve 3, the output end of the electromagnetic ball valve 3 is conductively connected to the input end of the proportional relief valve 2, and the output end of the proportional relief valve 2 is conductively connected to the input end of the balancing valve 1;

[0036] It should be noted that the balancing valve 1 controls the extension and retraction of the rust removal disc cylinder under non-preload conditions, adjusts the distance between the rust removal disc and the hull, ensures that the rust removal disc cylinder will not slide down under heavy load conditions, ensures that the load is stable and there are no safety hazards. Under rust removal conditions, the high-pressure oil on either side goes to the solenoid ball valve 3 through the shuttle valve 4, and the solenoid ball valve 3 receives an electrical signal to open. The hydraulic working oil is set to the maximum cylinder pressure by the proportional relief valve 2. The proportional relief valve 2 can output electrical signals according to different rust removal conditions, thereby providing different pre-pressures to achieve rust removal of rust layers of different thicknesses.

[0037] like Figure 5 As shown, the output end of the electromagnetic ball valve 3 is electrically connected to the input end of the proportional relief valve 2, and the three shuttle valves 4 are respectively connected to the corresponding cavities of the electromagnetic ball valve 3;

[0038] It should be noted that the high-pressure oil on either side goes to the solenoid ball valve 3 through the shuttle valve 4, the solenoid ball valve 3 receives an electrical signal to open, and the hydraulic working oil is set by the proportional relief valve 2 to set the maximum pressure of the cylinder. The proportional relief valve 2 can output electrical signals according to different rust removal working conditions, thereby providing different pre-pressures.

[0039] like Figure 1 、 Figure 2 As shown, the two access ports provided at the balancing valve 1 are respectively connected to the access ends of the rust removal disc;

[0040] The liquid flowing between the balancing valve 1, the proportional relief valve 2, the electromagnetic ball valve 3 and the shuttle valve 4 is hydraulic oil;

[0041] It should be noted that the balancing valve 1 controls the extension and retraction of the rust removal plate cylinder under non-preload conditions, adjusts the distance between the rust removal plate and the hull, ensures that the rust removal plate cylinder does not slide down under heavy load conditions, and ensures that the load is stable and there is no safety hazard.

[0042] The pilot ratio of the balancing valve 1 is 10:1 or 8:1.

[0043] The proportional relief valve 2 and the electromagnetic ball valve 3 both use waterproof grade IP69 plugs.

[0044] During use: The compression valve group on the ship rust removal equipment designed by the invention is composed of a balancing valve 1 with a large pilot ratio, a shuttle valve 4, an electromagnetic ball valve 3, and a proportional relief valve 2. The proportional relief valve 2 and the electromagnetic ball valve 3 both use waterproof grade IP69 plugs. The balancing valve 1 with a large pilot ratio has a pilot ratio of 10:1 or 8:1. It can be opened normally when the rust removal disc is pushed forward or away from the hull, and the oil cylinder is kept load locked under the condition of carrying a heavier rust removal disc. When in the rust removal condition, the electromagnetic ball valve 3 is opened by receiving an electric signal, and the proportional relief valve 2 is set to pre-compression pressure according to the different rust removal thickness, thereby ensuring that the rust removal disc always maintains a certain distance from the hull and the rust removal thickness is uniform.

[0045] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
