Description

Technical Field

[0001] This utility model relates to the field of pumping fixture technology, specifically to a novel pumping fixture for rapid pipe installation. Background Technology

[0002] To test the sealing and strength of the boiler membrane water-cooled wall tube bank, a high-pressure pump water test is conducted before installation. This involves injecting high-pressure water into the tube bank to simulate the pressure environment of the boiler under operating conditions, thereby checking for potential problems such as leakage or deformation. For bare tube banks of boiler membrane water-cooled walls, internal expansion plug pump water fixtures are often used for testing.

[0003] Patent application CN200910034435.7, entitled "Hydraulic Internal Expansion Plug Device," discloses a device comprising a sealing gasket, a water outlet nut, a pull rod, a nut, a washer, an expansion sleeve, a first sealing ring, a conical sleeve, a second sealing ring, a conical washer, an operating rod, a water outlet, a limiting body, and an annular groove. During operation, the hand acts on the operating rod, causing the water outlet nut to rotate, thereby pressing the sealing gasket between the end of the pull rod and the water outlet nut, preventing water from flowing from the water outlet. Alternatively, the sealing gasket between the water outlet nut and the end of the pull rod can be loosened, allowing water to flow from the water outlet. By rotating the nut, the conical sleeve expands the expansion sleeve, causing the first sealing ring within the annular groove of the expansion sleeve to press against the inner wall of the tube. Simultaneously, the conical washer causes the second sealing ring to expand and press against the inner wall of the tube. Place the sealing gasket between the drain nut and the pull rod. After filling with water, tighten the drain nut. Water enters and pressurizes through the inner expansion plug at the other end. After the water pressure test is completed, stabilize the pressure for 1 minute without dropping it. Slowly release the pressure to zero and then open the drain nut to release the water. The water pressure test is then successful.

[0004] In actual operation, the aforementioned device requires workers to manually rotate the nut to press the first sealing ring in the annular groove of the expansion sleeve against the inner wall of the tube, resulting in low work efficiency and high labor intensity for the workers. Utility Model Content

[0005] The purpose of this invention is to provide a novel pumping fixture for rapid pipe installation, in order to solve the problems mentioned in the background section.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel pumping fixture for quick pipe installation, which includes a pull rod. The pull rod is hollow. The first end of the pull rod is fitted with a cone, a sealing ring, a gasket, and a limiting component from the inside to the outside. A pawl is fitted on the cone. The second end of the pull rod has a water inlet that communicates with an external water inlet pipe along its longitudinal direction. A locking nut is fitted on the second end of the pull rod. A connecting component adapted to the water inlet pipe is installed between the locking nut and the cone.

[0007] Furthermore, the connector is a push sleeve, which is sleeved on the pull rod, and the inner end of the push sleeve has a U-shaped groove adapted to the water inlet pipe.

[0008] Furthermore, the pull rod is connected to the water inlet pipe via a water inlet screw, which is installed longitudinally in the water inlet.

[0009] Furthermore, the limiting member is detachably connected to the pull rod.

[0010] Furthermore, the limiting component is a limiting nut.

[0011] The beneficial effects of this utility model are as follows: By designing the water inlet as an L-shape and adding a connecting piece between the locking nut and the cone, this utility model allows the electric wrench to be easily connected and applied to the locking nut, thus changing the tightening method to electric, simplifying the operation process, improving work efficiency, shortening clamping time, and reducing the intensity of manual labor.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one embodiment of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To make the objectives, technical solutions and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0018] In the following description, references to "an embodiment," "an embodiment," "an example," "example," etc., indicate that the described embodiment or example may include a particular feature, structure, characteristic, property, element, or limitation, but not every embodiment or example necessarily includes that particular feature, structure, characteristic, property, element, or limitation. Furthermore, the repeated use of the phrase "an embodiment according to this application," while possibly referring to the same embodiment, does not necessarily refer to the same embodiment.

[0019] like Figure 1-2 As shown, this utility model discloses a novel pumping fixture for rapid pipe installation, comprising a pull rod 1, which is hollow. From the inside out, the first end of the pull rod 1 is fitted with a cone 2, a sealing ring 3, a gasket 4, and a limiting member 5. A claw 6 is fitted onto the cone 2. The second end of the pull rod 1 has a longitudinally arranged inlet for communication with an external water inlet pipe, i.e., the water inlet is L-shaped. A locking nut 7 is fitted onto the second end of the pull rod 1, and a connecting member 8 adapted to the water inlet pipe is installed between the locking nut 7 and the cone 2.

[0020] The water inlet method of the traditional internal expansion plug tool has been redesigned from type I to type L. A connecting sleeve is installed between the locking nut 7 and the cone 2, allowing an electric wrench to be easily connected and applied to the locking nut 7 without the need for additional adapters or tools. The traditional tightening method has been changed from manual to electric. The electric wrench, in conjunction with the locking nut 7, pushes the connecting piece 8 inward, thereby causing the cone to move inward while simultaneously pressing the jaws 6 outward to clamp the water pipe wall. This design simplifies the operation process, improves work efficiency, shortens clamping time, and reduces manual labor intensity.

[0021] This utility model designs the water inlet in an L-shape and adds a connecting piece 8 between the locking nut 7 and the cone 2, so that the electric wrench can be easily connected and applied to the locking nut 7, that is, the tightening method becomes electric, which simplifies the operation process, improves work efficiency, shortens clamping time, and reduces the intensity of manual labor.

[0022] In one embodiment, the connector 8 is a push sleeve 81, which is sleeved on the pull rod 1. The inner end of the push sleeve 81 has a U-shaped groove 82 adapted to the water inlet pipe. That is, the push sleeve 81 is sleeved on the pull rod 1 and slides along the pull rod 1 to a suitable position. During this movement, the U-shaped groove 82 at the inner end of the push sleeve 81 corresponds to the water inlet, that is, the water inlet pipe is located in the U-shaped groove 82, so that the water inlet pipe and the push sleeve 81 do not interfere with each other.

[0023] In one embodiment, the pull rod 1 is connected to the inlet pipe via an inlet screw 9, which is installed longitudinally in the inlet. The first end of the inlet screw 9 matches and connects to the inlet of the pull rod 1, while the second end engages with a nut on the inlet pipe. This design ensures the sealing performance of the pump fixture while simplifying its installation process and facilitating the installation of the inlet pipe.

[0024] In one embodiment, the limiting member 5 is detachably connected to the pull rod 1. When the sealing ring 3 is worn or damaged, the sealing ring 3 can be easily replaced by removing the limiting member 5, reducing downtime required for replacing the sealing ring 3 and thus lowering production costs.

[0025] In one embodiment, the limiting component 5 is a limiting nut, which facilitates installation and maintenance. That is, when installing the sealing ring 3, tightening the limiting nut ensures that the sealing ring 3 is correctly clamped between the cone 2 and the limiting nut, thereby avoiding complex assembly steps and positioning difficulties.

[0026] The design concept of this utility model embodiment is as follows:

[0027] The water inlet method of the traditional internal expansion plug tooling has been redesigned from type I to type L. A connecting piece 8 has been added between the locking nut 7 and the cone 2 to facilitate tightening of the locking nut 7. The first end of the pull rod 1 has been changed from the traditional T-shape to type I (that is, the step at the first end of the traditional pull rod 1 has been changed to a removable limiting nut) to facilitate the assembly of the sealing ring 3.

[0028] During operation, the first end of this pump fixture is placed into the water pipe, ensuring that the clamp 6 enters the pipe wall. Then, the locking nut 7 is tightened with an electric wrench. The locking nut 7 pushes the connecting piece 8 (i.e., the pushing sleeve 81) inward. The pushing sleeve 81 squeezes the clamp 6 outward through the cone 2. After the clamp 6 clamps the inner wall of the water pipe, water is introduced into the inlet pipe. The water enters the pull rod 1 through the inlet bolt and then into the water pipe. During the pressurization process after water is introduced, the gasket 4 at the first end of the pull rod 1 pushes the sealing ring 3 to expand outward along the diameter direction, tightly adhering to the inner wall of the water pipe until the water pressure test is completed.

[0029] This utility model designs the water inlet in an L-shape and adds a connecting piece 8 between the locking nut 7 and the cone 2, so that the electric wrench can be easily connected and applied to the locking nut 7, that is, the tightening method becomes electric, which simplifies the operation process, improves work efficiency, shortens clamping time, and reduces the intensity of manual labor.

[0030] The above description of the disclosed embodiments enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those 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 invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
