Description

Technical Field

[0001] This utility model belongs to the technical field of large-flow column-type hydraulic control bidirectional balance valve, specifically relating to a large-flow column-type hydraulic control bidirectional balance valve. Background Technology

[0002] The high-flow-rate, column-type, hydraulically controlled, two-way balancing valve is a core control component specifically designed for high-pressure, high-flow-rate hydraulic systems. This valve features a column-type structure and integrated two-way control function, precisely adjusting the flow direction and pressure to effectively prevent actuator stall or slippage due to load changes, ensuring stable and reliable equipment operation. Its unique hydraulic control design uses pilot pressure to drive the valve core, achieving efficient control of the main oil circuit. It can quickly respond to system pressure changes, improving the dynamic performance and operational safety of the hydraulic system. In terms of performance, the high-flow-rate, column-type, hydraulically controlled, two-way balancing valve features strong flow capacity, low pressure loss, and excellent sealing performance. Its maximum working pressure can reach tens of megapascals, and its flow rate range covers hundreds of liters per minute, making it suitable for various heavy-duty working conditions. With its excellent shock and vibration resistance, this valve is widely used in the hydraulic systems of engineering machinery, mining equipment, port machinery, and other fields, such as excavators, hydraulic supports, and cranes, providing strong protection for the safe and stable operation of the equipment.

[0003] Currently, existing high-flow column-type hydraulically controlled bidirectional balancing valves typically achieve liquid control by driving the internal valve core during use. However, the valve body of traditional high-flow column-type hydraulically controlled bidirectional balancing valves is often directly exposed to the outside and does not have a good protective structure. Therefore, the valve body may be damaged during subsequent use, thereby reducing the service life of the high-flow column-type hydraulically controlled bidirectional balancing valve. Utility Model Content

[0004] The purpose of this invention is to provide a high-flow-rate column-type hydraulically controlled bidirectional balancing valve, which aims to solve the problem that existing high-flow-rate column-type hydraulically controlled bidirectional balancing valves typically achieve liquid control by driving an internal valve core. However, the valve body of traditional high-flow-rate column-type hydraulically controlled bidirectional balancing valves is often directly exposed to the outside and does not have a good protective structure. Therefore, the valve body may be damaged during subsequent use, thereby reducing the service life of the high-flow-rate column-type hydraulically controlled bidirectional balancing valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large-flow column-type hydraulic control bidirectional balance valve, comprising a valve body, a valve seat fixedly connected to the top of the valve body, a first connecting pipe fixedly connected to one side of the valve body, and a second connecting pipe fixedly connected to the other side of the valve body;

[0006] The outer wall of the valve body is fitted with a protective plate, and two positioning blocks are fixedly connected to the bottom of the valve body.

[0023] 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.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a large flow column-type hydraulic control bidirectional balance valve, including a valve body 1, a valve seat 2 fixedly connected to the top of the valve body 1, a first connecting pipe 3 fixedly connected to one side of the valve body 1, and a second connecting pipe 4 fixedly connected to the other side of the valve body 1.

[0025] A protective plate 5 is fitted onto the outer wall of the valve body 1. Two positioning blocks 6 are fixedly connected to the bottom of the valve body 1. Limiting grooves 7 are opened on the outer walls of the two positioning blocks 6. Two positioning grooves 8 are opened at the bottom of the protective plate 5. An installation groove 9 is opened at the bottom of the protective plate 5. An installation seat 10 is fixedly connected inside the installation groove 9. A spring 11 is movably connected inside the installation seat 10. A movable block 12 is connected to the end of the spring 11. A limiting pin 13 is fixedly connected to one end of the movable block 12.

[0026] Preferably, one end of the limiting pin 13 extends through into the interior of the positioning groove 8, the through end of the limiting pin 13 is adapted to the size of the limiting groove 7, the size between the positioning block 6 and the positioning groove 8 is adapted, and the protective plate 5 can form an elastic locking structure with the valve body 1 through the positioning block 6, the limiting groove 7, the positioning groove 8, the mounting groove 9, the mounting seat 10, the spring 11, the movable block 12, and the limiting pin 13.

[0027] In practical use, the movable block 12 is moved by the lever to retract the limit pin 13, and then the protective plate 5 is put on the outer wall of the valve body 1 from the bottom. At this time, the positioning block 6 at the bottom of the valve body 1 will be embedded in the positioning groove 8. Then, by releasing the lever, the limit pin 13 can be popped out under the action of the spring 11 and inserted into the limit groove 7 on the outer wall of the positioning block 6, so that the protective plate 5 can be installed on the outer wall of the valve body 1. The protective plate 5 can protect the valve body 1, thereby improving the protection effect of the valve body 1.

[0028] Conversely, when maintenance of valve body 1 is required, the movable block 12 is moved by the toggle block to cause the limit pin 13 to retract. At this time, one end of the limit pin 13 will disengage from the limit groove 7 on the outer wall of the positioning block 6. Then, the positioning block 6 is disengaged from the positioning groove 8 by pulling the protective plate 5, thereby enabling the removal of the protective plate 5.

[0029] Preferably, the valve body 1 has two cover plates 14 symmetrically distributed on the top, and two first magnetic blocks 15 are fixedly connected to the bottom of the two cover plates 14. Two slots 16 are respectively opened at the ends of the protective plate 5. A second magnetic block 17 is fixedly connected inside the slot 16. The cover plate 14 can form a magnetic attraction structure with the protective plate 5 through the first magnetic block 15, the slot 16, and the second magnetic block 17.

[0030] In practical use, by symmetrically distributing two cover plates 14 on the top of the valve body 1, and then embedding the first magnetic block 15 at the bottom of the protective plate 5 into the slot 16, the magnetic attraction between the first magnetic block 15 and the second magnetic block 17 can be used to install and fix the protective plate 5, thereby covering the top of the valve body 1.

[0031] Working principle: First, by moving the movable block 12 with the lever, the limiting pin 13 retracts. Then, the protective plate 5 is fitted onto the outer wall of the valve body 1 from the bottom. At this time, the positioning block 6 at the bottom of the valve body 1 will be embedded in the positioning groove 8. Then, by releasing the lever, the limiting pin 13 can be ejected by the spring 11 and inserted into the limiting groove 7 on the outer wall of the positioning block 6. Thus, the protective plate 5 can be installed on the outer wall of the valve body 1. The protective plate 5 can protect the valve body 1, thereby improving the protection effect of the valve body 1. By symmetrically distributing the two cover plates 14 on the valve... The top of the valve body 1 is then inserted into the slot 16 by inserting the first magnetic block 15 at the bottom of the protective plate 5. At this time, the magnetic attraction between the first magnetic block 15 and the second magnetic block 17 can be used to fix the protective plate 5, thereby covering the top of the valve body 1. Conversely, when the valve body 1 needs maintenance, the movable block 12 is moved by the lever to drive the limit pin 13 to retract. At this time, one end of the limit pin 13 will disengage from the limit slot 7 on the outer wall of the positioning block 6. Then, by pulling the protective plate 5, the positioning block 6 is disengaged from the positioning slot 8, thereby enabling the removal of the protective plate 5.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
