Description

Technical Field

[0001] This invention relates to an anti-clogging progressive lubricant metering and dispensing method. Background Technology

[0002] In existing technologies, when lubricants are pumped under high pressure, the internal channels are complex, and the grease separates significantly under high pressure, which can easily cause the grease to clump together. In addition, the separate metering and outlet settings are complex in structure, time-consuming and labor-intensive in processing, and have low space utilization.

[0003] Although CN202511168071.7 discloses "a progressive allocator" and both achieve normal operation of the progressive allocator, their working principles are fundamentally different from those of this application in order to achieve progressive allocation.

[0004] The appendix to the disclosed patent Figure 1 , Figure 4 It is known that the metering chamber and the control chamber are separate. Therefore, multiple chambers need to be added to the pump body. Specifically, because the metering chamber exists, it also requires a corresponding sealing device, and each nozzle needs its own metering chamber, resulting in excessive volume. In terms of control, there are also fundamental differences between the two. The reversing mechanism presents obstacles, necessitating the addition of a neutral release component, leading to a complex structure prone to clogging. This component is also susceptible to damage, grease accumulation, and incomplete replacement, resulting in a high probability of grease hardening and subsequent blockages and malfunctions.

[0005] The present invention adopts a completely different design concept and solves the above-mentioned technical problems from another design perspective.

[0018] A clog-resistant progressive lubricant metering and dispensing method, utilizing a valve assembly; Perform the following steps; S1, the inlet connector is connected to the grease inlet section with positive pressure; S2, the grease enters the rod chamber k of the first valve chamber, the right rod chamber of the second valve chamber, and the right metering chamber of the first valve chamber through the main fluid path a; then, the grease enters the left metering chamber of the second valve chamber through the connecting hole c; next, the valve core B moves to the right, squeezing out the right metering chamber of the second valve chamber; then, the squeezed-out lubricant passes through the right rod chamber of the first valve chamber and enters the right outlet spray area of ​​the second valve chamber through the corresponding bypass hole; S3, the lubricant in the outlet injection zone pushes open the outer check valve A and is discharged from the outlet connector; S4. Simultaneously with step S3, valve core B reverses direction, and lubricating grease enters the rod chamber k in the first valve chamber, the left rod chamber in the second valve chamber, and the left metering chamber at the left end of the first valve chamber through the main fluid path a. S5, firstly, valve core A moves to the right to achieve reversal; then, the lubricant in the metering chamber at the right end of valve core A is squeezed out; then, the squeezed-out lubricant passes through the rod chamber on the right side of the first valve chamber, and the lubricant enters the right end outlet spray area of ​​the first valve chamber through the corresponding bypass hole. S6, the lubricant in the outlet injection zone pushes open the outer check valve A and is discharged from the outlet connector.

[0019] As a further improvement to the above technical solution: In steps S3 and S6, after the outlet injection zone passes through the one-way valve A, the discharged lubricant enters the adjacent outlet connector through the parallel through hole, realizing multiple outputs.

[0020] In step S2, when the valve core B moves to the right, when the left rod chamber of the first valve chamber is unable to move due to negative pressure, the elastic movable seat overcomes the second spring B and retracts, thereby opening with the side through hole and realizing the connection with atmospheric positive pressure.

[0021] When a blockage occurs, a high-pressure pump is connected to the outlet connector on one side and / or a negative pressure source is connected to the outlet connector on the other side, thereby driving the internal valve core A and / or valve core B to move and eliminate the malfunction.

[0022] In step S2; When valve core B includes driven plunger A, driven plunger B, and driven plunger C controlled sequentially; S2.1, Driven plunger A moves to the right; Lubricant enters the left metering chamber of driven plunger B; At the same time, driven plunger A moves to the right, discharging the lubricant in the right metering chamber d through chamber j.

[0023] A clog-resistant progressive lubricant metering and dispensing valve body is used to perform the above-mentioned dispensing method.

[0024] The metering valve core and outlet of this invention are concentric, thereby achieving low resistance and smoother lubricant discharge, greatly simplifying existing channel connection methods, making it simpler and more efficient; improving space utilization; reducing the probability of grease caking; reducing processing and material costs; this invention is reasonably designed, low in cost, sturdy and durable, safe and reliable, simple to operate, time-saving and labor-saving, cost-saving, compact in structure and easy to use.

[0025] This invention solves the problem of easy clogging in existing similar products. As a whole solution, it does not require a separate metering chamber, but cleverly combines the metering chamber with the reversing function. It cleverly utilizes the middle rod-shaped chamber to achieve oil discharge on one side and a channel cut-off on the other side, realizing coordinated reversing, thereby reducing the internal channel layout. Under the same volume, the internal space is increased. By layering in the thickness direction, the easily clogged channels are placed externally, which facilitates processing and later maintenance. The steel ball can be removed, eliminating the need for the middle reversing function, greatly simplifying the failure rate. It does not require a separate metering space, reducing the number of plugs. Through the clever staggered design of the valve chamber channel and the isolation of the oil outlet, the coaxial design has good manufacturability, is easy to process, and reduces the size.

[0026] The valve body of the present invention has a compact structure, smaller size, convenient processing, and good manufacturability. The first reversing linkage valve core B is realized through valve core A, and all valve cores realize the movement and reversing of oil discharge at the same time, so there is no waste and no problem of accumulated oil that cannot be discharged.

[0027] The outlet check valve connector features a clever design, with a double check valve structure and spring pressure, isolated from the coaxial valve body cavity. This reduces the complexity of the valve body structure, greatly simplifying the design, facilitating maintenance, preventing clogging, and creating a compact structure. It can be connected to external equipment to solve internal blockage problems, while also ensuring safety. It does not require a separate relief valve and can achieve parallel multi-output, while avoiding the problem of one outlet spraying more while others spray less.

[0028] This invention features a layered modular design, facilitating the disassembly and maintenance of the steel ball. The connector body can be adjusted according to actual conditions. The connecting engagement part can be a plug-in, threaded, or Parker connector. The sealing end achieves isolation, and the outlet spray zone enables energy storage and spraying. The peripheral channel group allows the channels to be externally located for easy maintenance. One-way valve A achieves one-way sealing and shut-off. It includes a side through hole, adjusting seat, elastic movable seat, end face sealing end, and a second spring B to prevent negative pressure and ensure safety, preventing one-way valve A from jamming and becoming inoperable. Simultaneously, the cooperation of the two one-way valves cleverly drives the movement of the internal valve core, solving the blockage problem. The sealing platform has an ingenious process design, with an inner stop and an outer stop at the outlet for separation, internal energy storage, and external connection. The bypass hole enables parallel connection.

[0029] The bypass orifice allows for lubricant storage and connects to other valve chambers; the lubricant discharged from the parallel orifice is distributed to multiple outlets; in order to achieve uniform distribution, the injection orifice enables pressurized injection and adjustment, avoiding different injection volumes at each outlet due to different distances.
