Description

Technical Field

[0001] The utility model relates to a high-pressure pipeline repair device, in particular to a pressure-bearing clamp. Background Art

[0002] During normal operation, if an ordinary water pipe is damaged by external forces (for example, accidentally cracked by an excavator), the liquid in the pipe will be quickly discharged in the form of a jet due to the high pressure usually maintained inside the pipe.

[0003] In such emergencies, the traditional remedial measure is to immediately cut off the supply to the damaged area to facilitate repair work. While this method can effectively control the leak, it also means that the area will temporarily lose water supply, which will have a significant impact on daily activities such as residents' lives and industrial production. The entire repair process often takes a long time, further exacerbating the inconvenience. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a pressure-bearing clamp, which can perform emergency temporary repairs on pipelines. The annular clamp body is installed with a tightening part and a sealing gasket. The inner diameter of the clamp body is changed by the action of the tightening part, so that the sealing gasket fits tightly to the damaged part of the pipeline, thereby achieving temporary repair of the damaged part, so that the staff can repair it by cutting off the supply during non-peak hours.

[0005] Specifically, a pressure-bearing clamp includes an annular clamp body having an open groove, one side of the open groove is a connecting portion, and the other end is a clamping portion.

[0006] A tightening member for controlling the width of the opening slot is installed on the opening slot, one end of the tightening member is connected to the connecting portion, and the other end is movably connected to the force transmission member engaged with the engaging portion;

[0007] A flexible sealing gasket is laid on the inner ring of the hoop body.

[0008] Optionally, the tightening member is a screw rod, which passes through the force transmission member and is fixed in position by a nut, and the width of the open slot is adjusted by the position of the nut on the screw rod.

[0009] Optionally, two mutually parallel tightening members are installed on the opening groove.

[0010] Optionally, a plurality of circumferential and / or axial ridges are provided on the inner side of the sealing gasket.

[0011] Optionally, the sealing gasket is in the shape of a strip and has an adjustment seam after being bent into a circle.

[0012] Preferably, the sealing gasket is HPEM rubber.

[0013] Optionally, an arc-shaped plate is provided on the inner side of the opening groove and is in contact with the sealing gasket.

[0014] Optionally, guard ribs are provided on both sides of each screw rod, and the guard ribs are fixed to the connecting portion.

[0015] Optionally, the bottom of the force transmission member is engaged in the groove of the engaging portion, and the upper portion contacts the end of the guard plate rib.

[0016] The utility model has the following advantages:

[0017] The utility model is a pressure-bearing clamp, which can realize emergency temporary remediation of pipelines; by adopting a screw-type tightening member, a strong tightening force is provided for the open groove, which can quickly and effectively seal the damaged part of the pipeline, effectively avoiding further leakage of high-pressure liquid, and ensuring the safety and stability of the pipeline system.

[0018] By designing the cooperation between two screw-type tightening parts and the force transmission part, the tightening force at the opening groove is further improved, so that the clamp can better withstand the high-pressure environment, and its reliability and durability in practical applications are enhanced.

[0019] By installing guard ribs on both sides of the two screw-type tightening members and fixing them to the clamping portion, the force transmission member can be fully supported by the guard ribs during the force-bearing process, thereby ensuring that the hoop opening can withstand greater tension. At the same time, the two parallel guard ribs can also protect the screws, effectively preventing them from deflecting or bending during the tension process, further improving the strength and stability of the clamp.

[0020] In addition, by rationally designing the sealing gasket and setting circumferential ridges on its inner side, when the sealing gasket comes into contact with the pipeline, the circumferential ridges can form several circles of sealing rings, which significantly improves the sealing performance and greatly reduces the risk of liquid leakage, thereby ensuring the normal operation and safety of the pipeline system.

DETAILED DESCRIPTION

[0029] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0030] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0031] As mentioned in the background, the traditional remedial measure is to immediately cut off the supply to the damaged area to facilitate repair work. While this method can effectively control the leak, it also means that the area will temporarily lose water, significantly impacting daily activities such as residents' lives and industrial production. Furthermore, the entire repair process often takes a long time, further exacerbating the inconvenience.

[0032] Based on the above reasons, this embodiment provides a pressure-bearing clamp, including an annular clamp body 100, the clamp body having an open groove, one side of the open groove is a connecting portion 102, and the other end is a clamping portion 101.

[0033] A tightening member 300 for controlling the width of the opening slot is installed on the opening slot. One end of the tightening member 300 is connected to the connecting portion, and the other end is movably connected to a force transmission member 400 engaged with the engaging portion.

[0034] A flexible sealing pad 200 is laid on the inner ring of the hoop. Preferably, two mutually parallel tightening members are installed on the open groove.

[0035] Exemplarily, the tightening member 300 is a screw, one end of which passes through the force transmission member 400 and is fixed in position by a nut 500 attached to the outside of the force transmission member 400. The width of the open groove is adjusted by the position of the nut 500 on the screw; and the other end of the screw is connected to the connecting part by threaded connection or welding.

[0036] The aforementioned technical features, through the use of a screw-type tightening element, provide a strong tightening force at the open slot, enabling rapid and effective sealing of damaged pipes, effectively preventing further leakage of high-pressure liquids and ensuring the safety and stability of the pipeline system. The design of two screw-type tightening elements in conjunction with the force transmission element further enhances the tightening force at the open slot, allowing the clamp to better withstand high-pressure environments and enhancing its reliability and durability in practical applications.

[0037] In order to improve the sealing performance of the sealing gasket after being attached to the pipe, in one embodiment, a plurality of circumferential and / or axial ridges 201 are provided on the inner side of the sealing gasket 200; preferably, the sealing gasket is made of HPEM rubber.

[0038] In order to make the sealing gasket adapt to water pipes with more diameters, in one embodiment, the sealing gasket is in the shape of a strip, which is bent into a circle to have an adjustment seam 202 , and the adjustment seam is an open through groove with an inclined cross-section.

[0039] To improve the pressure-bearing capacity of the open slot, in one embodiment, a curved plate 700 is positioned inside the open slot to fit the sealing gasket. The width of the curved plate is greater than the width of the open slot, allowing both sides of the curved plate to be positioned inside the hoop. Preferably, the sealing gasket is provided with a curved plate mounting groove 203 to facilitate installation and positioning of the curved plate. The curved plate presses down on the sealing gasket at the open slot, thereby improving pressure-bearing capacity and the seal between the sealing gasket and the pipe.

[0040] To enhance the stability of the screws, in one embodiment, guard ribs 600 are provided on both sides of each screw, secured to the connecting portion. The bottom of the force transmission member engages with the groove in the engaging portion, while the top contacts all the guard ribs. These guard ribs provide greater support to the force transmission member, ensuring that the hoop opening can withstand greater tension. The two parallel guard ribs also protect the screws, preventing them from deflecting or bending during tension.

[0041] When the above-mentioned pressure-bearing clamp is in use, the sealing gasket, arc plate and hoop body are first put on the pipeline, located not far from the damaged part of the pipeline, and then the screw member is installed. One end of the screw passes through the thickness of the force transmission member and is connected to the connecting part by threaded connection or welding. The force transmission member is engaged in the groove of the engaging part, and then a nut is installed on the screw. The nut is located on the outside of the force transmission member. At this time, the force transmission member contacts the end of the guard plate rib; then the sealing gasket and the hoop body are moved axially to the damaged part, and then the nut is rotated to tighten the open groove, and the sealing gasket is tightly pressed against the damaged part through the hoop body, thereby achieving temporary remediation of the pipeline.

[0042] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
