Description

Technical Field

[0001] This utility model relates to the field of valve-related technology, and in particular to a bidirectional overflow valve. Background Technology

[0002] A valve is a mechanical device used to control the flow of fluids. It can open or close flow channels to regulate the flow rate and pressure of fluids. Valves are widely used in various industrial fields, such as petroleum, chemical, water treatment, power, food and beverage industries. They can be made of various materials, such as metals, plastics, and rubber, to adapt to different working environments and fluid characteristics. In the throttling and regulating system of a fixed displacement pump, relief valves are often used. Therefore, in order to use relief valves efficiently, a two-way relief valve is particularly needed.

[0003] When controlling the pump outlet pressure through the relief valve, a large amount of sediment may accumulate inside the relief valve due to long-term use, which may reduce the flow rate inside the relief valve. The residual sediment may accumulate inside the relief valve, and may even cause the relief valve to fail to close. Therefore, when the relief valve fails to close during the process of controlling the pump outlet pressure, the relevant personnel will shut down the entire hydraulic pump and disassemble and replace the relief valve. However, this solution cannot quickly solve the problem of the relief valve failing to close due to sediment accumulation, and it will increase the workload of the relevant personnel.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 The present invention provides a technical solution: a two-way overflow valve, including a packaging box body 1, including an overflow valve body 1, and a filter mechanism 2 is provided on the overflow valve body 1;

[0022] The filter mechanism 2 includes a slide groove 21, a connecting hole 22, a first spring 23, a control ring 24, a limiting block 25, a filter tube 26, and a first fixing block 27. The inner wall of the overflow valve body 1 has a slide groove 21, and the inner wall of the slide groove 21 has a connecting hole 22. The first spring 23 is installed inside the connecting hole 22. The outer wall of the overflow valve body 1 is fitted with a control ring 24, and the inner wall of the control ring 24 has a limiting block 25. A filter tube 26 is installed at one end of the overflow valve body 1, and the outer wall of the filter tube 26 has a first fixing block 27. Through the arrangement of the slide groove 21, connecting hole 22, first spring 23, control ring 24, limiting block 25, filter tube 26, and first fixing block 27, in use, the first spring 23 is installed into the slide groove 21, and the limiting block 25 is installed into the slide groove 21, with one end of the limiting block 25 passing through the connecting hole 22 and connecting to the control ring 24. Next, the first fixing block 27 on the outer wall of the filter tube 26 is aligned with the slide groove 21 and inserted. At this time, the first fixing block 27 will push the limiting block 25 into the slide groove 21. Then, the first fixing block 27 is rotated so that the first fixing block 27 is locked into the corner of the slide groove 21. At this time, the limiting block 25, which is no longer pushed by the first fixing block 27, will pop out under the action of the first spring 23, filling the slide groove 21 and preventing water from leaking from the connection hole 22 when the overflow valve body 1 is in use. The sediment generated by the overflow valve body 1 during long-term use will be blocked by the filter tube 26. When a certain amount is accumulated, the valve 12 is closed and the control ring 24 is pulled to pull the limiting block 25 into the slide groove 21, so that the first fixing block 27 can be rotated. Then, the filter tube 26 is rotated, removed and cleaned, and then reinstalled into the water pipe 11 for reuse.

[0023] Furthermore, the overflow valve body 1 includes a water pipe 11 and a valve 12. The water pipe 11 is equipped with a valve 12. With the water pipe 11 and the valve 12, during use, the valve 12 can be opened in a timely manner as the pressure of the hydraulic system increases, so as to guide the excess flow back to the oil tank, thereby maintaining the constant pump outlet pressure.

[0024] Furthermore, the grooves 21 are symmetrically opened along the central axis of the water pipe 11, and the connecting holes 22 are respectively opened in the corresponding grooves 21. With the setting of the grooves 21, the filter pipe 26 is installed into the interior of the water pipe 11 through the grooves 21 during use, which simplifies the installation process of the filter pipe 26.

[0025] Furthermore, one end of the first spring 23 is connected to a connecting hole 22, and the other end of the first spring 23 is connected to a limiting block 25. With the setting of the first spring 23, when in use, the first spring 23 will pop the limiting block 25 outward at the first moment when the limiting block 25 loses the push of the first fixing block 27.

[0026] Furthermore, the overflow valve body 1 is provided with a folding mechanism 3, which includes a first mounting groove 31, a mounting plate 32, a fixing groove 33, a limiting groove 34, a connecting plate 35, a second fixing block 36, a second mounting groove 37, a second spring 38, a latch 39, and a handle 310. The valve 12 has a first mounting groove 31, the inner wall of which is provided with a mounting plate 32, the outer wall of which is provided with a fixing groove 33, the inner wall of which is provided with a limiting groove 34, the outer wall of which is provided with a connecting plate 35, the outer wall of which is fixed with a second fixing block 36, the second fixing block 36 having a second mounting groove 37, the interior of which is provided with a second spring 38, one end of which is provided with a latch 39, and the outer wall of which is fixed with a handle 310. The valve 12 is connected to the first mounting groove 31, the mounting plate 32, the fixing groove 33, and the second mounting plate 32. The limiting groove 34, connecting plate 35, second fixing block 36, second mounting groove 37, second spring 38, bolt 39, and handle 310 are configured as follows: In use, the mounting plate 32 is installed into the first mounting groove 31 on the valve 12 control plate; the second spring 38 and bolt 39 are installed into the second mounting groove 37 on the second fixing block 36; and the connecting plate 35, which is fixed with the second fixing block 36, is fixed to both sides of the handle 310. Then, the handle is installed into the first mounting groove 31, and the second fixing block 36 is engaged in the fixing groove 33. When it is necessary to control the opening and closing of the overflow valve body 1, the handle 310 is pulled out from the first mounting groove 31. At this time, the bolt 39 is repeatedly squeezed into the second mounting groove 37 by the partition between the limiting groove 34 and the limiting groove 34 until the handle 310 is adjusted to a suitable position. Then, the opening and closing size of the valve 12 can be controlled by pulling the handle 310.

[0027] Furthermore, the mounting plate 32 is symmetrically arranged with respect to the width of the first mounting groove 31, and the limiting groove 34 is symmetrically opened with respect to the width of the fixing groove 33. With the arrangement of the first mounting groove 31, the handle 310 can be stored in the valve 12 control plate through the first mounting groove 31 during use, reducing the overall area of ​​the valve 12 control plate and thus reducing the possibility of misoperation.

[0028] Furthermore, the second fixing block 36 is symmetrically arranged with respect to the central axis of the connecting plate 35, and the second spring 38 is symmetrically arranged with respect to the central axis of the second mounting groove 37. With the arrangement of the second spring 38, during use, the second spring 38 will pop out the latch 39 immediately after the latch 39 leaves the gap between the limiting groove 34 and the limiting groove 34.

[0029] Furthermore, the latches 39 are respectively set in the corresponding second mounting slots 37, and the connecting plates 35 are symmetrically arranged with respect to the central axis of the handle 310. By setting the handle 310, the overall area of ​​the valve 12 control plate is reduced during use by the foldable handle, thereby reducing the possibility of misoperation.

[0030] Working principle: In use, the first spring 23 is installed into the slide groove 21, and the limiting block 25 is installed into the slide groove 21, with one end of the limiting block 25 passing through the connecting hole 22 and connecting to the control ring 24. Then, the first fixing block 27 on the outer wall of the filter tube 26 is aligned with the slide groove 21 and inserted. At this time, the first fixing block 27 will push the limiting block 25 into the slide groove 21. Then, the first fixing block 27 is rotated so that it is locked into the corner of the slide groove 21. At this time, the limiting block 25, which is no longer pushed by the first fixing block 27, will pop outward under the action of the first spring 23, filling the slide groove 21 and preventing water leakage from the connecting hole 22 when the overflow valve body 1 is in use. The sediment generated by the overflow valve body 1 during long-term use will be blocked by the filter tube 26. When a certain amount is accumulated, the valve 12 is closed and the control ring 24 is pulled to push the limiting block 25 into the slide groove 21. Pulling the first fixing block 27 allows it to rotate, then rotating the filter tube 26 to remove and clean it, and then reinstalling it into the water pipe 11 for reuse. The mounting plate 32 is installed into the first mounting groove 31 on the valve 12 control plate. The second spring 38 and the latch 39 are installed into the second mounting groove 37 on the second fixing block 36. The connecting plate 35, which is fixed with the second fixing block 36, is fixed on both sides of the handle 310. Then the handle is installed into the first mounting groove 31, and the second fixing block 36 is inserted into the fixing groove 33. When it is necessary to control the opening and closing of the overflow valve body 1, the handle 310 is pulled out from the first mounting groove 31. At this time, the latch 39 is repeatedly squeezed into the second mounting groove 37 by the partition between the limiting groove 34 and the limiting groove 34 until the handle 310 is adjusted to the appropriate position. At this time, the opening and closing size of the valve 12 can be controlled by pulling the handle 310.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
