Technical Field
[0001] The utility model belongs to the technical field of one-way throttle valve connection, and specifically relates to a stacked double-sided one-way throttle valve. Background Technique
[0002] A throttle valve adjusts the flow rate or changes the pressure before and after the valve by changing the flow cross-section when the oil flow passes through the throttle valve. For a one-way throttle valve, it throttles when the oil flow is in the forward direction. When the oil flow is in the reverse direction, the oil pressure pushes the valve core, causing the valve core and the valve body to form a large channel, without throttling effect, and thus becoming a one-way valve.
[0003] Currently, the common structural forms of one-way valves are such as LDF-B1OH, LDF-LIOH, etc. Valves of this form have the problems of large volume, occupying a large space in the combined system, and only throttling the forward oil flow during operation, while the reverse oil flow becomes a one-way valve without throttling effect, unable to achieve two-way throttling. Therefore, it is necessary to design and transform the stacked double-sided one-way throttle valve to effectively prevent the phenomenon of unable to achieve two-way throttling. Content of the Utility Model
[0004] To solve the problems raised in the above background technique, the purpose of the present utility model is to provide a stacked double-sided one-way throttle valve, which has the advantage of being able to perform two-way throttling, and solves the problems of the common structural forms of one-way valves such as LDF-B1OH, LDF-LIOH, etc., which have the problems of large volume, occupying a large space in the combined system, and only throttling the forward oil flow during operation, while the reverse oil flow becomes a one-way valve without throttling effect, unable to achieve two-way throttling.

[0006] The beneficial effects of the present utility model are as follows:
[0007] 1. In the present utility model, whether the oil flows through the device in the forward direction or the reverse direction, the oil can be throttled, thereby achieving two-way throttling. The operator can rotate the first threaded rod to make the first threaded rod move leftward, thereby driving the conical block to move to the left. Under the action of the conical block, the valve seat moves. At this time, the valve seat will move toward the side close to the limiting ring, thereby compressing the spring, and then increasing the pressure required for the oil to push the valve core, thereby achieving the role of auxiliary throttling.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0015] As Figures 1 to 5 shown, the stacked double-sided one-way throttle valve of this embodiment includes a first one-way throttle valve body 1. The top of the first one-way throttle valve body 1 is connected to a second one-way throttle valve body 2. Inside both the first one-way throttle valve body 1 and the second one-way throttle valve body 2, an oil delivery pipe 3 is fixedly connected. The inner wall of the oil delivery pipe 3 is provided with a sliding groove, and a valve seat 4 is movably connected inside the sliding groove. A valve core 5 is movably connected inside the valve seat 4. A limiting ring 12 is fixedly connected to the inner wall of the oil delivery pipe 3, and the limiting ring 12 is movably connected to the valve core 5. A spring 6 is fixedly connected to the surface of the valve seat 4, and the spring 6 is fixedly connected to the valve core 5. Inside both the first one-way throttle valve body 1 and the second one-way throttle valve body 2, a first threaded rod 7 is threadedly connected. A conical block 8 is fixedly connected to the surface of the first threaded rod 7, and the conical block 8 is movably connected to the valve seat 4. A through port 9 is opened on the surface of the oil delivery pipe 3. Inside both the first one-way throttle valve body 1 and the second one-way throttle valve body 2, a second threaded rod 10 is threadedly connected. A throttle block 11 is fixedly connected to the surface of the second threaded rod 10, and the throttle block 11 is movably connected to the through port 9. The first one-way throttle valve body 1 and the second one-way throttle valve body 2 have the same width, the same length, and the same height. The first one-way throttle valve body 1 and the second one-way throttle valve body 2 are welded together. The surface of the spring 6 is sprayed with an anti-rust coating.
[0016] Refer to Figures 1 to 5, gaskets 13 are movably connected to the surfaces of the first one-way throttle valve body 1 and the second one-way throttle valve body 2. Fastening bolts 14 are threadedly connected to the surfaces of the first threaded rod 7 and the second threaded rod 10. The fastening bolts 14 are movably connected to the gaskets 13. The number of gaskets 13 is several, and the surfaces of the fastening bolts 14 are sprayed with anti-rust paint.
[0017] In this embodiment, through the arrangement of the gasket 13 and the fastening bolt 14, when the operator tightens the fastening bolt 14, the operator keeps the first threaded rod 7 and the second threaded rod 10 stationary, and then tightens the fastening bolt 14 so that the fastening bolt 14 is in close contact with the gasket 13. According to the relationship between action and reaction, the fastening bolt 14 exerts a lateral force on the first threaded rod 7 and the second threaded rod 10, thereby increasing the pressure between the first threaded rod 7 and the second threaded rod 10 and the first one-way throttle valve body 1 and the second one-way throttle valve body 2, and then locking the first threaded rod 7 and the second threaded rod 10 to prevent the first threaded rod 7 and the second threaded rod 10 from rotating.
[0018] Reference Figure 1 and Figure 3 , adjusting grooves 15 are provided on the surfaces of the first threaded rod 7 and the second threaded rod 10. The shape of the adjusting groove 15 is rectangular.
[0019] In this embodiment, through the arrangement of the adjusting groove 15, the operator can insert one end of a screwdriver into the adjusting groove 15 and then rotate the screwdriver, thereby driving the first threaded rod 7 and the second threaded rod 10 to rotate, which is convenient for the operator to rotate the first threaded rod 7 and the second threaded rod 10.
[0020] Reference Figure 2 and Figure 5 , oil passing holes 16 are provided on the surface of the valve seat 4. The number of oil passing holes 16 is several, and the oil passing holes 16 are evenly distributed in a ring on the surface of the valve seat 4.
[0021] In this embodiment, through the arrangement of the oil passing holes 16, it is convenient for the oil to pass through the valve seat 4.
[0022] Reference Figure 1 , flanges 17 are sleeved on the surfaces of the first one-way throttle valve body 1 and the second one-way throttle valve body 2. Mounting openings 18 are provided on the surfaces of the flanges 17. The number of mounting openings 18 is several, and the mounting openings 18 are evenly distributed in a ring on the surface of the flanges 17.
[0023] In this embodiment, through the arrangement of the flanges 17 and the mounting openings 18, it is convenient for the operator to connect the first one-way throttle valve body 1 and the second one-way throttle valve body 2 to the pipeline.
[0024] Reference Figures 1 to 5, the first one-way throttle valve body 1, the second one-way throttle valve body 2, the valve seat 4, the valve core 5, the limit ring 12, the first threaded rod 7, the second threaded rod 10, the throttle block 11, the oil pipeline 3 and the cone block 8 are all made of stainless steel.
[0025] In this embodiment, the first one-way throttle valve body 1, the second one-way throttle valve body 2, the valve seat 4, the valve core 5, the limit ring 12, the first threaded rod 7, the second threaded rod 10, the throttle block 11, the oil pipeline 3 and the cone block 8 made of stainless steel have the advantages of corrosion resistance and high hardness.
[0026] The oil fluid enters the oil pipeline 3 from the bottom of the first one-way throttle valve body 1. The valve core 5 in the first one-way throttle valve body 1 is in close contact with the limit ring 12. At this time, the oil fluid cannot flow from the limit ring 12 into the second one-way throttle valve body 2. At this time, the operator rotates the second threaded rod 10, causing the throttle block 11 to move to the left, thereby adjusting the flow cross-sectional area formed between the throttle block 11 and the port 9, and then realizing the throttling effect. The oil fluid enters the second one-way throttle valve body 2 through the port 9. The oil fluid pushes the valve core 5 in the second one-way throttle valve body 2 to move upward, thereby compressing the spring 6 in the second one-way throttle valve body 2. At this time, the oil fluid smoothly passes through the second one-way throttle valve body 2. During this process, the oil fluid is throttled in the first one-way throttle valve body 1 and smoothly flows through the second one-way throttle valve body 2. Similarly, when the oil fluid flows back from the top of the second one-way throttle valve body 2, the flowing-back oil fluid cannot flow into the first one-way throttle valve body 1 through the limit ring 12. Similarly, the operator rotates the second threaded rod 10, causing the throttle block 11 to move to the left, adjusting the flow cross-sectional area formed between the throttle block 11 and the port 9, and then realizing the throttling effect. The flowing-back oil fluid flows into the first one-way throttle valve body 1 through the port 9 in the second one-way throttle valve body 2. The oil fluid will push the valve core 5 in the first one-way throttle valve body 1 to move downward. The oil fluid passes through the limit ring 12 in the first one-way throttle valve body 1 and then through the oil pipeline 3. During the process of the oil fluid flowing back, the oil fluid is throttled inside the second one-way throttle valve body 2 and smoothly passes through the inside of the first one-way throttle valve body 1. In summary, whether the oil fluid flows through this device in the forward direction or flows back through this device in the reverse direction, the oil fluid can be throttled, thereby realizing two-way throttling. For example, the operator can rotate the first threaded rod 7, causing the first threaded rod 7 to move to the left, thereby driving the cone block 8 to move to the left. Under the action of the cone block 8, the valve seat 4 moves. At this time, the valve seat 4 will move toward the side close to the limit ring 12, thereby compressing the spring 6, and then increasing the pressure required for the oil fluid to push the valve core 5, and then realizing the auxiliary throttling effect.
