Description

Technical Field

[0001] This utility model relates to the field of drain valve disassembly technology, and in particular to a tool for disassembling the drain valve of a boiler plunger pump. Background Technology

[0002] In the extraction of heavy oil in oilfields, steam needs to be injected into the well. When the steam injection boiler is running, a plunger pump is needed to provide high-pressure water. During the operation of sewage, due to the high temperature and poor water quality, the drain valve is in a high-pressure and high-temperature medium environment for a long time. The valve cover and valve seat are prone to corrosion, scaling or medium residue, making disassembly difficult.

[0003] Traditional manual disassembly methods require the use of tools such as wrenches and pry bars to forcibly pry open the valves. Some rusted drain valves even require the entire pump head to be lifted and disassembled by a crane. This method is labor-intensive, involves a large amount of manpower and resources, and results in a long shutdown time. It not only consumes a lot of manpower and resources but may also cause damage to the sealing surface of the drain valve seat, which seriously affects the reassembly accuracy and sealing performance of the equipment.

[0004] Therefore, it is necessary to provide a new tool for disassembling the boiler plunger pump discharge valve to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a tool for disassembling the drain valve of a boiler plunger pump.

[0006] The boiler plunger pump discharge valve disassembly tool provided by this utility model includes: a disassembly seat, a discharge valve seat on one side of the disassembly seat, a connecting rod fixedly connected at equal intervals at one end of the disassembly seat near the discharge valve seat, and a pull claw for disassembling the discharge valve seat fixedly connected at one end of the connecting rod away from the disassembly seat.

[0007] Preferably, the outer wall of the multiple sets of pull claws is threaded.

[0008] Preferably, the internal design of all the pull claws is a right angle.

[0009] Preferably, one side of each of the multiple sets of pull claws has an arc-shaped design.

[0010] Compared with related technologies, the boiler plunger pump discharge valve disassembly tool provided by this utility model has the following advantages:

[0011] Improve disassembly efficiency and safety: By combining the disassembly base, connecting rod, and pull claw, the pull claw's outer wall thread directly screws into and fixes the drain valve seat, replacing traditional prying or hoisting operations. This significantly reduces labor intensity and workload, and shortens shutdown maintenance time. At the same time, it avoids safety hazards such as tool slippage and parts falling during manual operation, significantly improving disassembly efficiency and operational safety.

[0012] Protect valve seat structure and assembly precision: The right-angled design and curved contour of the pull claw allow it to precisely fit the edge of the drain valve seat, providing a uniform and stable gripping force. This avoids stress concentration and damage to the sealing surface. Compared to traditional forceful disassembly, this tool achieves smooth force application through threaded connection and structural fit, effectively protecting the structural integrity of the drain valve seat, ensuring the accuracy of equipment reassembly and sealing performance, and reducing secondary maintenance costs caused by disassembly.

[0014] The following are the labels in the diagram: 1. Disassembly seat; 2. Drain valve seat; 3. Connecting rod; 4. Pull claw. Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figures 1 to 3 A tool for disassembling the drain valve of a boiler plunger pump, comprising: a disassembly seat 1, a drain valve seat 2 on one side of the disassembly seat 1, a connecting rod 3 fixedly connected at equal intervals to one end of the disassembly seat 1 near the drain valve seat 2, and a pull claw 4 for disassembling the drain valve seat 2 fixedly connected to one end of the connecting rod 3 away from the disassembly seat 1, wherein the outer wall of the pull claw 4 is threaded, the interior of the pull claw 4 is right-angled, and one side of the pull claw 4 is arc-shaped.

[0018] It should be noted that the connecting rod 3 provides stable support for the pull claw 4. The right-angle design allows the pull claw 4 to be embedded inside the drain valve seat 2, and the axial force is applied evenly to prevent slippage and protect the sealing surface. The arc-shaped design of the pull claw 4 can fit the arc-shaped inner wall of the drain valve seat 2, so that the pull claw 4 can have a larger contact area with the inner wall of the drain valve seat 2.

[0019] The working principle of the boiler plunger pump discharge valve disassembly tool provided by this utility model is as follows: Disassembly of drain valve seat 2: In use, place the device near the drain valve seat 2 of the boiler plunger pump. The disassembly base 1 serves as a support foundation, providing a stable point of force for the entire disassembly operation. The connecting rods 3, which are fixedly connected at equal intervals at one end of the disassembly base 1, connect the disassembly base 1 and the pull claw 4, ensuring that the pull claw 4 can stably transmit force during the disassembly process. Align the pull claw 4 with the drain valve seat 2, and utilize the threaded design on the outer wall of the pull claw 4 to make it threadedly connected with the drain valve seat 2 by rotating the pull claw 4. After tight screwing, a stable mechanical connection is formed. The right-angle design inside the pull claw 4 allows the pull claw 4 to better fit the edge of the drain valve seat 2, enhancing the gripping force between the pull claw 4 and the drain valve seat 2, and preventing slippage or uneven force during disassembly. At the same time, the arc design on one side of the pull claw 4 matches the outer contour of the drain valve seat 2, providing gripping force while avoiding damage to the drain valve seat 2 due to local stress concentration.

[0020] After the connection and fixation of the pull claw 4 and the drain valve seat 2 are completed, a pulling force is applied to the disassembly seat 1. The pulling force of the disassembly seat 1 is transmitted to the pull claw 4 through the connecting rod 3. The pull claw 4, by means of the threaded connection and structural fit with the drain valve seat 2, converts the pulling force into a disassembly force on the drain valve seat 2, and gradually disassembles the drain valve seat 2 from the boiler plunger pump.

[0021] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
