Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic equipment, in particular to a hydraulic accident isolation valve device. Background Art

[0002] In the operation of iron and steel metallurgical industrial equipment, the operation of metallurgical equipment mostly relies on hydraulic actuators - hydraulic cylinders or hydraulic motors, etc. The hydraulic system includes a power source, a control part, an execution part and an auxiliary part. The control part controls the action of the actuator. A system requires the cooperation of multiple actuators to complete a task. The hydraulic system has a high degree of integration, and the multi-channel parallel control part is integrated in a hydraulic valve block. The system power source usually comes from the same pump station.

[0003] Since the system power source usually comes from the same pump station, when one of the branches fails, stopping the entire system for maintenance will cause huge economic losses to the production line, especially for equipment with multiple sets of the same actuators. Only isolating the faulty parallel branch while the other branches operate normally can minimize the loss from the accident. However, the traditional isolation valve only considers the functional valve group behind the isolation valve and the failure of the cylinder and pipeline, but does not consider the failure of the isolation valve itself. How to restore the equipment operation when there are no spare parts, and there is currently no unified isolation valve size standard, the interchangeability of spare parts is poor, and its practicality needs to be improved.

When the isolation valve body itself fails, the corresponding oil ports of the functional valve group on the main valve block can play a role, and the functional valve group can be fixed to the main valve block for continued use, thereby restoring the normal function of the hydraulic branch as soon as possible. Since the device takes into account the isolation function of the isolation valve body to the current hydraulic circuit and the rapid restoration of the hydraulic system function when the isolation valve body itself fails during application, it can ensure the efficient and green operation of the hydraulic system and further improve its practicality.

[0025] Example

[0026] like Figure 1 - Figure 3 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient practicality of the existing device, and the overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a hydraulic emergency isolation valve device, including a main valve block 11, an isolation valve body 12 is arranged at the upper end of the main valve block 11, and the isolation valve body 12 adopts a channel design inside to realize the required hydraulic valve of the isolation function in series or in parallel, and a functional valve group 13 is arranged at the upper end of the isolation valve body 12;

[0028] The main valve block 11 and the isolation valve body 12 are respectively provided with a detachable isolation mechanism on their upper surfaces;

[0029] The detachable isolation mechanism includes a first connection area 14 (the first connection area 14 is Figure 2 The second connection area 15 is located inside the first connection area 14. A plurality of first screws are arranged inside the first connection area 14 on the main valve block 11. Each of the first screws can be threadedly mounted with the isolation valve body 12. The upper surfaces of the main valve block 11 and the isolation valve body 12 are respectively provided with second connection areas 15 that comply with the ISO4401 standard. The second connection area 15 is Figure 2 The part within the dotted box.

[0030] The second connection area 15 on the main valve block 11 is provided with a plurality of first screw holes on its surface. The detachable isolation mechanism further comprises a first oil port, a second screw, a second screw hole, and a second oil port. Each of the first screw holes is located at the four corners of the second connection area 15. Each of the first oil ports is provided inside the second connection area 15. Each of the second screws is provided on the surface of the second connection area 15 on the isolation valve body 12. Each of the second screws is threadedly mounted with the functional valve group 13. Each of the second screw holes is provided inside the second connection area 15 on the isolation valve body 12. Each of the second oil ports is provided on the second connection area 15 on the isolation valve body 12. Inside the area 15, each second oil port is located between the second screw holes, and each second oil port can be adapted to the oil port of the functional valve group 13. By fixing the isolation valve body 12 in the first connection area 14 on the main valve block 11, and fixing the functional valve group 13 in the second connection area 15 on the isolation valve body 12, when a control element, actuator or pipeline accessory of this branch fails, the isolation valve body 12 can close the inlet and outlet oil pipes of this branch, isolating the branch from the rest of the same system, thereby facilitating the maintenance of the faulty branch, while ensuring the normal operation of other branches, thereby improving practicality.

[0031] The second oil port at the second connection area 15 on the isolation valve body 12 is compatible with the oil port of the functional valve group 13, the first screw at the first connection area 14 on the main valve block 11 can be threadedly installed with the functional valve group 13, the first screw hole at the second connection area 15 on the main valve block 11 can be installed with the functional valve group 13 using additional screws, and the second screw hole at the second connection area 15 on the isolation valve body 12 can be installed with the functional valve group 13 using additional screws. The above-mentioned second connection areas 15 all comply with the ISO4401 installation standard and can be used to fix the functional valve group 1 3. Both first connection areas 14 are only used to fix the isolation valve body 12. When the isolation valve body 12 itself fails, the isolation valve body 12 can be removed, and the second connection area 15 on the main valve block 11 can directly fix the functional valve group 13, thereby restoring the normal function of the hydraulic branch as soon as possible. Since the device takes into account the isolation function of the isolation valve body 12 on the current hydraulic circuit and the rapid restoration of the hydraulic system function when the isolation valve body 12 itself fails during application, it can ensure the efficient and green operation of the hydraulic system and further improve its practicality.
