Description

Technical Field

[0001] This utility model relates to the field of regeneration valve equipment technology, specifically to an energy-saving regeneration valve for oil return and reuse. Background Technology

[0002] An energy-saving regenerative valve is a specially designed valve primarily used in fluid control systems. Its purpose is to improve the overall energy efficiency of the system by optimizing fluid flow paths and reducing energy loss. These valves are commonly used in heat exchange systems, air conditioning systems, refrigeration systems, and other applications requiring efficient fluid control.

[0003] Current energy-saving regenerative valves in general hydraulic systems are limited to the addition of accumulators for energy saving. The accumulators provide the system pressure required for a certain period of time. When the accumulator pressure is released, the power source needs to replenish the pressure in time. This process of repeated pressurization and release can prevent the power source from being in a working state all the time, thus achieving a certain degree of energy saving. Therefore, existing regenerative energy-saving valves still require a power source to provide a certain amount of power output when in use. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] To address the technical problems in the background section, an energy-saving regeneration valve for oil return and reuse is provided as follows:

[0031] Includes front cover 1, rear cover 2, and main valve body 4, such as Figure 3 The front cover 1 and the rear cover 2 are provided with a main valve body 4; the main valve body 4 includes a valve core control assembly 5 and a valve core reversing assembly 6; as... Figure 4 The specific connection channels between the valve core control assembly 5 and the valve core reversing assembly 6 are as follows: Figure 1 As shown, the oil inlet 11 is connected to the valve core reversing assembly 6, and the oil inlet 11 supplies oil to the valve core reversing assembly 6; and the oil inlet 11 is connected to the valve core control assembly 5 through the second check valve 8, and the oil inlet 11 supplies oil to the valve core control assembly 5 through the second check valve 8; the end of the valve core control assembly 5 connected to the second check valve 8 is connected to the oil outlet 9 through the first check valve 7; the valve core control assembly 5 is connected to the valve core reversing assembly 6; the valve core control assembly 5 and the valve core reversing assembly 6 are connected to the return oil port 10.

[0032] Specifically, the valve core control assembly 5 includes a flow channel 21, a piston chamber 22, a piston body 23, a pressure boosting chamber 24, and a pressure boosting valve core 25; one side of the piston chamber 22 is connected to the pressure boosting chamber 24, for example, as shown in... Figure 1As shown, the right side of the piston chamber 22 is connected to the pressure chamber 24, and the piston body 23 is slidably connected inside the piston chamber 22; the side of the piston body 23 is connected to the pressure valve core 25, and the pressure valve core 25 is slidably connected to the pressure chamber 24; a flow groove 21 is formed on the outer surface of the end of the pressure valve core 25 that is connected to the piston body 23; the one-way valve 7 and the one-way valve 8 are connected to one side of the pressure chamber 24, specifically the one-way valve 7 and the one-way valve 8 are connected to the right side of the pressure chamber 24, and the piston... One side of the piston chamber 22 is connected to the return port 10 via oil passage 4 16. That is, the piston chamber 22 is divided into two parts by the piston body 23, including a cavity on the right side of the piston body 23 and a cavity on the left side of the piston body 23. The cavity on the right side of the piston body 23 is connected to the return port 10 via oil passage 4 16. The other side of the piston chamber 22 is connected to the valve core reversing assembly 6 via oil passage 6 18 and oil passage 7 19. That is, the cavity on the left side of the piston body 23 is connected to the valve core reversing assembly 6 via oil passage 6 18 and oil passage 7 19.

[0033] The states of the piston body 23 and the pressure boosting valve core 25 during movement are as follows:

[0034] When the piston body 23 and the booster valve core 25 are at the leftmost end, the booster chamber 24 is connected to the valve core reversing assembly 6 through oil passage 3 15 and oil passage 2 14, thereby repositioning the valve core reversing assembly 6.

[0035] When the piston body 23 and the booster valve core 25 are at the rightmost end, the second oil passage 14, the third oil passage 15, the flow groove 21, the piston chamber 22, the fourth oil passage 16 are connected to the return oil port 10; and the valve core reversing assembly 6 is reset.

[0036] The valve core reversing assembly 6 includes a first cavity 26, a second cavity 27, and a reversing valve body 28; the two ends of the reversing valve body 28 form the first cavity 26 and the second cavity 27; one end of the reversing valve body 28 is connected to the oil inlet 11, the first oil passage 12, and the seventh oil passage 19; the other end of the reversing valve body 28 is connected to the second oil passage 14; one end of the reversing valve body 28 is connected to the return oil port 10 through the ninth oil passage 13; the sixth oil passage 18 is connected to the third oil passage 15 through the fifth oil passage 17.

[0037] The width of the boosting chamber 24 is the same as the width of the boosting valve core 25, and the cross-section of the boosting valve core 25 adopts an inverted "T" shape.

[0038] When the energy-saving regenerative valve of this utility model is in use, the input pressure oil enters through the oil inlet 11 and acts on the cavity 27 at the left end of the directional valve body 28 via the oil passage 12, keeping the directional valve body 28 in the left position. At this time, the oil passage 7 19 is connected to the oil passage 9 13 through the directional valve body 28. At the same time, the pressure oil in the oil inlet 11 enters the booster chamber 24 through the oil passage 8 20 and the check valve 2 8, pushing the booster valve core 25, which acts on the right end of the piston body 23, causing the piston body 23 and the booster valve core 25 to move to the left as a whole. At this time, the hydraulic pressure in the left end of the piston chamber 22... Oil flows through oil passage 6 (18), oil passage 7 (19), directional valve body 28, and oil passage 9 (13) back to return port 10. When the booster valve core 25 pushes the piston body 23 to the leftmost end, oil passage 3 (15) connects to the booster chamber 24. The piston body 23 and booster valve core 25 no longer move. The pressurized oil in the booster chamber 24 acts on the right end cavity 1 (26) of the directional valve body 28 through oil passage 3 (15) and oil passage 2 (14). Because the area of ​​the right end cavity 1 (26) of the directional valve body 28 is larger than the area of ​​the left end cavity 2 (27), the same pressure results in greater force. The force applied at cavity 26 is relatively large, pushing the valve core of the reversing valve body 28 to reverse. At this time, the oil inlet 11 is connected to the oil passage 19 through the reversing valve body 28, putting the reversing valve body 28 in the right position. At this time, the pressure oil at the oil inlet 11 enters the left end of the piston chamber 22 through port A of the reversing valve body 28, oil passage 19, and oil passage 18, causing the piston body 23 to move to the right, pushing the booster valve core 25 to move to the right, and outputting the high pressure oil in the booster chamber 24 to the oil outlet 9 through the check valve 7. At the same time, the pressure oil is replenished through oil passage 17. The pressure is filled in the cavity 26 of the reversing valve, keeping it in the right position. When the booster valve core 25 moves to the rightmost end, the oil passage 3 15 is connected to the right side cavity of the piston cavity 22 through the flow groove 21 and is connected to the oil passage 4 16. That is, the oil passage 3 15 is connected to the oil passage 4 16 through the flow groove 21. The pressure oil acting on the right end cavity 26 of the reversing valve body 28 returns to the return port 10 through the oil passage 2 14, oil passage 3 15, flow groove 21, and oil passage 4 16. The reversing valve body 28 is reversed to the left position. This movement is repeated to achieve continuous high pressure output.

[0039] To facilitate the connection of the energy-saving regeneration valve for oil return reuse with the oil return tank, valve block, accumulator, etc., the oil outlet 9, the oil return port 10, and the oil inlet 11 extend outward to form a connector 3, such as... Figure 2 As shown, the connector 3 is connected to the connecting pipe 33. The connecting pipe 33 is connected to the return oil tank, valve block, accumulator, etc., and then the connector 3 is connected to the connecting pipe 33 to complete the installation of the energy-saving regeneration valve, which is convenient for subsequent use.

[0040] like Figure 5 and Figure 6As shown, the connector 3 includes a first sealing ring 29, a positioning ring 30, a second sealing ring 31, and an outer tube 32; the inner wall of the outer tube 32 is provided with a positioning ring 30, and the inner wall of the outer tube 32 is provided with a first sealing ring 29 and a second sealing ring 31; one end of the connecting tube 33 forms a plug 34; the plug 34 is engaged with the positioning ring 30.

[0041] In order to lock the inserted plug 34 and prevent the connecting tube 33 from falling off after connection, the outer wall cross-section of the insertion end of the plug 34 is a triangular structure, and the cross-section of the positioning ring 30 is an arc-shaped structure with one end and an inclined structure; the inclined structure of the positioning ring 30 is matched with the triangular structure of the plug 34.

[0042] To enhance overall sealing performance and prevent leakage, the inner wall of the sealing ring 29 is inclined, and the inclined structure of the sealing ring 29 is adapted to the triangular structure of the plug 34; the outer wall of the sealing ring 31 protrudes outward to form a rectangular and triangular cross-section, and the outer wall of the sealing ring 31 is adapted to the inner wall of the outer tube 32.

[0043] To further enhance the tightness and sealing of the connection between the connecting pipe 33 and the connector 3, both the outer tube body 32 and the outer wall of the connecting pipe 33 are provided with threaded structures, which cooperate with the locking sleeve 35; the locking sleeve 35 is used to strengthen the connection between the outer tube body 32 and the connecting pipe 33.

[0044] A groove is provided at the center of the inner wall of the locking sleeve 35, and a sealing ring 36 with an arc-shaped cross-section is provided in the groove; the sealing ring 36 and the groove are connected to a sealing ring 4 with an inclined cross-section; the sealing ring 4 is used to enhance the sealing performance of the connection between the outer tube 32 and the connecting tube 33.

[0045] When installing the regeneration valve, insert the plug 34 of the connecting pipe 33 into the connector 3. When the plug 34 is inserted, it passes through the sealing ring 2 31. Press the positioning ring 30 until the plug 34 completely passes through the positioning ring 30. The positioning ring 30 has the elasticity to return to its original position and limits the plug 34. At this time, the plug 34 is matched with the sealing ring 1 29. The locking sleeve 35 is initially positioned on the outer tube 32. After the plug 34 is inserted, rotate the locking sleeve 35 so that the locking sleeve 35 rotates into the connecting pipe 33. When rotating, press the sealing ring 4 37. The sealing ring 4 37 presses the sealing ring 36. Until the groove of the locking sleeve 35 is aligned with the connecting pipe 33 and the outer tube 32, the sealing ring 4 37 is pushed out by the elasticity of the sealing ring 36, sealing the connection between the connecting pipe 33 and the outer tube 32.

[0046] This utility model's energy-saving regenerative valve features a novel and simple oil passage design between the valve core reversing assembly and the valve core control assembly, facilitating maintenance, easy processing, and low cost. The connection between the valve core reversing assembly, the valve core control assembly, and the return oil port enables the collection and reuse of a portion of the system's return oil; it converts low-pressure return oil into high-pressure output; and it significantly improves energy efficiency and reduces consumption in the hydraulic system.

[0047] The energy-saving regeneration valve of this utility model has a connector that can be quickly connected to external connecting parts by plugging in. The specially structured connector is easy to operate and has better sealing performance. At the same time, the locking sleeve can further enhance the sealing performance while strengthening the connection stability.
