Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing technology, and in particular to a handheld ultra-high pressure hydraulic pipe sealing device. Background Technology

[0002] In many industrial sectors, as well as in municipal engineering, fire rescue, and other scenarios, there is often a need to urgently seal pipelines. For example, when a petrochemical pipeline leaks, it is necessary to quickly cut off the flow of the medium inside the pipeline to prevent further leakage of harmful substances and the resulting greater damage; or, in the event of a sudden rupture in an urban water supply and drainage network, it is necessary to promptly seal the pipe and carry out emergency repairs to ensure normal water supply for residents and prevent sewage overflow.

[0003] Traditional pipe sealing methods have many drawbacks. Mechanical clamp-type sealing devices often rely on manual tightening, which is insufficient for larger diameter pipes, prone to loosening under high pressure, resulting in poor sealing performance, and are time-consuming and labor-intensive. Simple rubber plug sealing, while adaptable to different pipe diameters to some extent, has limited sealing performance and cannot withstand ultra-high pressure conditions. Once the pressure inside the pipe becomes too high, the rubber plug is easily blown open, leading to sealing failure. In addition, some existing simple sealing tools lack convenient power connection methods, making it difficult to work efficiently with modern hydraulic power sources and failing to meet the actual needs of rapid response and efficient sealing. As industrial technology continues to advance into the ultra-high pressure field, there is an urgent need for a handheld sealing device that can adapt to ultra-high pressure conditions, is easy to operate, and provides reliable sealing to cope with increasingly complex pipeline maintenance and emergency handling scenarios. Utility Model Content

[0004] This utility model addresses the aforementioned problems in the existing technology by providing a handheld ultra-high pressure hydraulic pipe sealing device.

[0005] The objective of this utility model is mainly achieved through the following solution:

[0006] A handheld ultra-high pressure hydraulic sealing device, comprising:

[0007] Quick couplings are used to connect to an external hydraulic power source to introduce high-pressure hydraulic oil to power the sealing unit.

[0008] The switching valve is located inside the oil cylinder of the sealing device body to perform sealing or unsealing operations on the oil passage inside the oil cylinder;

[0009] A hydraulic cylinder is used to house a piston and withstand the pressure of high-pressure hydraulic oil.

[0010] The handle is located on the main body of the sealing device;

[0011] The movable blade is integrated with the piston of the hydraulic cylinder and is driven by the piston to move. It is used to cooperate with the fixed blade to seal the pipeline.

[0012] The fixed blade is fixed together with the movable frame and works in conjunction with the movable blade to seal the pipe;

[0013] The movable frame and pins are used to attach the movable frame to the main body of the sealing device.

[0014] Preferably, both the movable blade and the fixed blade are made of forged tool steel, and the end thickness of the movable blade and the fixed blade is 2-4 mm, and they are arranged in parallel.

[0015] Therefore, compared with the prior art, the present invention has the following advantages:

[0016] (1) This utility model connects to an external hydraulic power source and uses high-pressure hydraulic oil to drive the piston to move the moving blade. It works in conjunction with the fixed blade to achieve efficient sealing of the pipeline. It is especially suitable for ultra-high pressure conditions, can withstand the huge pressure in the pipeline, effectively prevents the leakage of the medium, and provides reliable protection for industrial production and emergency treatment.

[0017] (2) This utility model is suitable for large-diameter pipes, and compared with traditional pipe sealing tools, it greatly improves the size range of pipes that can be sealed;

[0018] (3) The handle provided by this utility model makes it convenient for operators to use in complex environments. The structure of the movable frame and pins allows the sealing device to be quickly installed before sealing. The operation is simple and quick, greatly shortening the preparation time before sealing and improving the efficiency of sealing on site.

[0019] (4) The moving blade and the fixed blade in this utility model are made of forged tool steel, which has high strength and high toughness. They are not easy to break under ultra-high pressure extrusion. The blade end is designed with a certain thickness, which not only prevents cutting the pipe but also ensures parallel extrusion sealing, avoids shearing damage to the pipe, and ensures the stability and sealing of the sealing.

[0023] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0024] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the field. Unless otherwise specified, the methods in the following embodiments are conventional methods in the field. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0025] like Figure 1 As shown, this utility model provides a technical solution: a handheld ultra-high pressure hydraulic sealing device, comprising:

[0026] Quick connector 1 is used to connect to an external hydraulic power source to introduce high-pressure hydraulic oil to provide power to the main body of the sealing device. As the connection hub between the sealing device and the external hydraulic power source, quick connector 1 is responsible for introducing high-pressure hydraulic oil. Its interface is compatible with common hydraulic pipelines to ensure a tight and leak-free connection, providing the power basis for the entire sealing operation.

[0027] Switch valve 2 is located inside the cylinder 3 of the sealing device body, and is used to seal or unseal the oil passage inside cylinder 3; for example... Figure 2 As shown, its conical tip structure plays a key role in different operating states. When loosened, it ensures that the internal oil passage is unobstructed, allowing the hydraulic oil to drive the piston smoothly. When tightened, the conical surface tightly squeezes the internal pipe, sealing or releasing pressure, and achieving precise control of the sealed state. However, it is not limited to the above structure; it is only necessary to achieve the sealing and unobstructed flow of the oil passage in cylinder 3.

[0028] Hydraulic cylinder 3 is used to house the piston and withstand the pressure of high-pressure hydraulic oil; it is made of aerospace aluminum alloy, which reduces the overall weight while having excellent pressure resistance, ensuring stable operation in ultra-high pressure environment;

[0029] Handle 4 is welded or bolted to the main body of the sealing device; it is ergonomically designed to fit the operator's hand grip habits, and has anti-slip texture on the surface to facilitate a stable grip on the sealing device during operation, ensuring precise operation even in harsh environments such as dampness and oil.

[0030] The movable blade 5 is connected to the piston of the hydraulic cylinder 3 by bolts and is driven by the piston to move, and is used to cooperate with the fixed blade 6 to seal the pipeline.

[0031] The fixed blade 6 is bolted or welded to the movable frame 7, serving as a static support component for sealing the tube and working in conjunction with the moving blade.

[0032] The movable frame 7 has a U-shaped structure. Its two ends can be detachably installed on the main body of the sealing device through pins 8. It can be opened and closed easily. Before sealing the pipe, the movable frame 7 is opened and placed on the pipe, and then the pins 8 are inserted to fix it. This provides precise positioning for the sealing operation and greatly improves the sealing efficiency. It is especially suitable for the rapid processing of pipes in different positions in complex field environments.

[0033] Pin 8, as a fixed connector of the movable frame, has a simple structure but high reliability. It is easy and quick to insert and remove, ensuring that the movable frame is firmly locked during the sealing process, thus ensuring the safe and smooth progress of the sealing operation.

[0034] Specifically, both the movable blade 5 and the fixed blade 6 are made of forged tool steel, and the end thickness of the movable blade 5 and the fixed blade 6 is 2-4mm. They are also arranged in parallel to each other to ensure sufficient strength and sealing effect.

[0035] The following provides specific construction details:

[0036] In a petrochemical pipeline emergency repair scenario, assuming a pipeline transporting high-pressure crude oil leaks at a certain point, the operator quickly arrives at the scene carrying the handheld ultra-high-pressure hydraulic sealing device described in this application. First, the quick connector 1 is tightly connected to the ultra-high-pressure hydraulic power source on site, ensuring the connection is secure and leak-free, laying a solid foundation for subsequent operations. Next, the pin 8 on the movable frame 7 is removed, the movable frame 7 is opened, and the front end of the sealing device is placed on the section of the pipeline that needs to be sealed. The outer diameter of the pipeline is adapted to the 80mm diameter design of the sealing device. Then, the pin 8 is inserted to securely fix the movable frame 7, allowing the sealing device to be precisely positioned at the leaking section of the pipeline. At this point, the switch valve 2 is loosened, the external hydraulic power source is activated, and high-pressure hydraulic oil enters the cylinder 3 through the quick connector 1, pushing the piston to the left. The connected moving blade 5 also moves closer to the fixed blade 6. Due to the movement... Both the moving blade 5 and the fixed blade 6 are made of forged tool steel with an end thickness of 3mm (within the 2-4mm design range). They are set in parallel and smoothly compress and seal the pipeline during movement to prevent crude oil leakage. The entire process is efficient and stable. When the initial sealing is completed and a hydraulic power source is needed to power other emergency repair tools, the operator tightens the switch valve 2. Its conical tip tightly squeezes the internal pipeline of the oil cylinder 3, sealing the internal hydraulic oil passage. Even if the hydraulic power source is removed, the pipe sealer maintains the sealing state of the pipeline, ensuring the continued safe operation of the emergency repair work. After the emergency repair is completed, the switch valve 2 is loosened again. The internal oil pressure drops, and the moving blade 5 automatically resets under the rebound force of the spring inside the piston. The operator removes the pin 8, takes off the pipe sealer, cleans and maintains it, and it is ready for the next emergency use.

[0037] In various similar scenarios, such as emergency repairs of urban water supply and drainage networks and control of water pipelines at fire rescue sites, the handheld ultra-high pressure hydraulic pipe sealing device of this application can efficiently complete the pipeline sealing task with its superior performance, playing a key role in ensuring the order of production and life and reducing disaster losses.

[0038] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
