Description

Technical Field

[0001] The utility model relates to the technical field of oilfield operation equipment, and more specifically to a quickly replaceable plunger sealing rubber ring for a fracturing vehicle. Background Art

[0002] The plunger sealing rubber ring used in fracturing trucks is an important sealing component, which is mainly used to seal the contact surface between the hydraulic plunger and the plunger cylinder to prevent hydraulic oil leakage and maintain the sealing and normal operation of the system. In the hydraulic system of the fracturing truck, the plunger sealing rubber ring plays a key role, ensuring that the hydraulic system can accurately transmit pressure and realize various operating functions.

[0003] However, when the fracturing truck is working, the plunger sealing rubber ring may be worn or damaged due to long-term high temperature, high pressure and frequent work, and needs to be replaced regularly. The traditional plunger sealing rubber ring is easily twisted and deformed during replacement, so it needs to be adjusted many times. The operation is cumbersome and wastes a lot of time. In addition, when replacing the sealing rubber ring, the original sealing rubber ring needs to be disassembled, which is difficult to disassemble and requires the purchase of special disassembly tools, resulting in additional cost expenditure. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a quickly replaceable plunger sealing rubber ring for a fracturing vehicle to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: a quickly replaceable plunger sealing rubber ring for a fracturing vehicle, wherein a sealing rubber ring element is fixedly connected to the surface of the mounting column near the bottom, a rotating knob is movably sleeved to the surface of the mounting column near the top, a thread is provided on the surface of the mounting column where the rotating knob is movably sleeved, a connecting top block is fixedly connected to the top of the mounting column, a disassembly disk is fixedly connected to the end of the connecting top block away from the mounting column, a rubber soft cover is movably connected to the top of the disassembly disk, and the rubber soft cover is conducive to sealing the top of the disassembly disk;

[0006] Furthermore, an arc-shaped circular groove is provided at the top of the disassembly disk at the position of the movably connected rubber soft cover, and neatly arranged disassembly cones are provided in the arc-shaped circular groove. The disassembly cones are used to facilitate disassembly of the original sealing rubber ring, which is easy to operate and saves cost expenditure.

[0007] Furthermore, the rotating knob is provided with a cylindrical groove at the position of the movable sleeve mounting column, the rotating knob surface is provided with neatly arranged anti-skid grooves around it, and a circular cutting knife is provided at the bottom of the rotating knob. The anti-skid groove helps to increase friction and prevent slipping when the rotating knob is rotated.

[0008] Furthermore, a connecting rod is provided on the surface of the mounting column near the bottom where the sealing rubber ring element is fixedly connected, and the sealing rubber ring element can be fixed by the connecting rod.

[0009] Furthermore, a handle is provided at the top of the soft rubber cover, a mounting slot is provided at the bottom of the soft rubber cover, and conical slots are provided around the bottom of the soft rubber cover. The soft rubber cover can be used to close the top of the disassembly tray to prevent the disassembly cone from injuring the staff when not in use.

[0010] Technical effects and advantages of the utility model:

[0011] 1. The utility model is provided with a mounting column and a rotating knob, which is conducive to directly sending the sealing rubber ring element to the plunger installation position, and then rotating the rotating knob so that the rotating knob drives the circular cutting knife to cut the connecting rod, so that the sealing rubber ring element can be directly pushed to the installation position, preventing the sealing rubber ring element from twisting and deforming during installation. The operation is simple and quick, saving a lot of time.

[0012] 2. The utility model is provided with a disassembly disk and a disassembly cone, which is beneficial for the disassembly cone in the disassembly disk to pierce into the interior of the original sealing rubber ring when the original sealing rubber ring is disassembled, so that the original sealing rubber ring can be quickly disassembled, and the sealing rubber ring can be used for installation and disassembly, saving the cost of purchasing tools.
