Description

Technical Field

[0001] This utility model relates to the field of pressure boosting valve technology, specifically a guide device for a pressure boosting valve. Background Technology

[0002] A booster valve is an industrial device that converts low-pressure oil in a hydraulic transmission system into high-pressure oil in a proportional manner. It is generally used as a pressure control valve on hydraulic or pneumatic equipment, and can also be used in other devices to increase air or liquid pressure. The guiding device of a booster valve usually includes a guide sleeve, guide ring, piston, etc., which are used to limit the radial movement of the piston or valve core and ensure that it moves along the axis.

[0003] In existing pressure booster valve guide devices, it is inconvenient to install a lubrication structure inside the guide sleeve and reduce the contact surface between the piston rod and the guide sleeve as the piston rod moves along the axis. This results in a problem of high friction between the piston rod and the guide sleeve during the movement of the piston rod. To address this, we propose a guide device for pressure booster valves. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A guiding device for a pressure booster valve includes: a guiding mechanism and a lubrication assembly; the guiding mechanism includes a guide sleeve, a piston rod movably installed inside the guide sleeve, and pistons locked at both ends of the piston rod by nuts; the lubrication assembly includes multiple sets of reinforcing ribs arranged and fixedly installed on the inner wall of the guide sleeve, a lubrication cavity formed between the reinforcing ribs inside the guide sleeve, recesses arranged at both ends of the guide sleeve, steel balls movably installed in each recess, and sealing caps movably installed at both ends of the guide sleeve.

[0007] Preferably, the lubrication cavity is also filled with lubricant.

[0008] Preferably, each of the sealing caps also has a sealing opening inside.

[0009] Preferably, a sealing ring is also movably installed inside each of the sealing openings.

[0010] Preferably, threaded holes and mounting holes are respectively provided at both ends of the guide sleeve and between them and the sealing cover.

[0011] Preferably, screws are also movably installed in both the threaded hole and the mounting hole.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1. In this utility model, the lubricant in the lubrication cavity between the reinforcing ribs inside the guide sleeve, and the steel balls installed in the recesses at both ends of the guide sleeve, can reduce the friction between the piston rod inside the guide sleeve and the guide sleeve during lateral adjustment, thereby reducing the wear of the guide sleeve and the piston rod and improving the service life of the guide mechanism inside the booster valve. At the same time, the reinforcing ribs arranged inside the guide sleeve can also ensure the overall strength of the guide sleeve and restrain the movement position of the piston rod to avoid the problem of skewing during movement.

[0014] 2. In this utility model, the sealing caps at both ends of the guide sleeve are installed by screws, and the sealing rings at their inner ends can also ensure the seal between the two ends of the guide sleeve and the piston rod, thereby avoiding leakage between the guide sleeve and the piston rod.

[0022] 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 specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a guide device for a pressure booster valve.

[0024] Example 1:

[0025] Combination Figure 1-4As shown, the present invention provides a guiding device for a booster valve, comprising: a guiding mechanism 100 and a lubrication assembly 200; the guiding mechanism 100 includes a guide sleeve 101, a piston rod 102 movably installed within the guide sleeve 101, and pistons 103 locked at both ends of the piston rod 102 by nuts; the lubrication assembly 200 includes multiple sets of reinforcing ribs 201 arranged and fixedly installed on the inner wall of the guide sleeve 101, a lubrication cavity 202 formed between the reinforcing ribs 201 within the guide sleeve 101, and a lubrication cavity 202 formed at both ends of the guide sleeve 101. The notch 203 is provided, the steel ball 204 is movably installed in the notch 203, the sealing cover 205 is movably installed at both ends of the guide sleeve 101, the lubrication cavity 202 is also filled with lubricant, the sealing cover 205 is also provided with a sealing port 206, and the sealing port 206 is also movably installed with a sealing ring 207. The guide sleeve 101 is provided with a threaded hole 208 and a mounting hole 209 respectively between its two ends and the sealing cover 205, and the threaded hole 208 and the mounting hole 209 are also movably installed with screws 210.

[0026] Specifically, a booster valve is a type of booster device. The guiding mechanism of a booster valve typically includes a guide sleeve, guide ring, and piston, used to limit the radial movement of the piston or valve core, ensuring its axial movement. The lubricant in the lubrication cavity 202 between the reinforcing ribs 201 within the guide sleeve 101 of this guiding mechanism 100, and the steel balls 204 installed in the recesses 203 at both ends of the guide sleeve 101, all reduce friction between the piston rod 102 and the guide sleeve 101 during lateral adjustment, thereby reducing wear on both the guide sleeve 101 and the piston rod 102 and improving the service life of the guiding mechanism 100 within the booster valve. Simultaneously, the reinforcing ribs 201 arranged within the guide sleeve 101 also ensure the overall strength of the guide sleeve 101 and provide support and restraint for the movement of the piston rod 102, preventing… To address the issue of misalignment during movement, the sealing caps 205, which are locked at both ends of the guide sleeve 101 by screws 210, and the sealing rings 207 at their inner ends, ensure a seal between the guide sleeve 101 and the piston rod 102, thereby preventing leakage between the guide sleeve 101 and the piston rod 102. The lubricant filled in the lubrication cavity 202 is a fixed lubricant, which can be used to lubricate the reinforcing ribs 201 and the steel balls 204 to reduce friction with the piston rod 102. At the same time, the sealing caps 205, which are sealed at both ends of the guide sleeve 101, can also reduce the loss of lubricant in the guide sleeve 101 to maintain a good lubrication effect for a long time. The screws 210 installed in the threaded holes 208 and the mounting holes 209 are mainly used for locking and fixing the sealing caps 205 at both ends of the guide sleeve 101 after installation.

[0027] Working principle and usage process of this utility model:

[0028] When the piston rod 102 inside the guide sleeve 101 moves along the axis for adjustment, the lubricant in the lubrication cavity 202 inside the guide sleeve 101 can lubricate the piston rod 102, reinforcing rib 201 and steel ball 204 in the guide sleeve 101. This reduces the friction between the piston rod 102 and the reinforcing rib 201 and steel ball 204 during movement, thereby reducing the wear of the guide sleeve 101 and piston rod 102 during use. At the same time, the sealing caps 205 at both ends of the guide sleeve 101, which are locked and fixed by screws 210, can also ensure the sealing between the two ends of the piston rod 102 and the guide sleeve 101 through their own sealing rings 207 at their inner ends. This can also prevent the lubricant inside the guide sleeve 101 from leaking out, thus ensuring the lubrication effect for a long time.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
