Description

Technical Field

[0001] The utility model relates to the field of hydraulic valves, in particular to a hydraulic valve with high stability. Background Art

[0002] Hydraulic control valves are automatic valves that use hydraulic power to open, close, and adjust the valve's opening. They are widely used in water supply networks, including hydraulic irrigation, high-rise buildings, fire protection systems, municipal water supply and drainage, and power plants. They can automatically control water levels, reduce pressure, release pressure, maintain pressure, regulate, check, and eliminate water hammer. Attached piping and pilot valves can be modified as needed to achieve specific functions. The hydraulic control valve's operating principle is driven by the pressure differential between the upstream and downstream sides of the piping system. Through the control of a pilot valve, the diaphragm (piston) hydraulically operates differentially, achieving automatic hydraulic regulation. This allows the main valve disc to be fully open, fully closed, or in a regulating position.

[0003] When connecting a water pipe to a hydraulic valve, due to the presence of a flange, the worker needs to tighten multiple bolts so that the water pipe needs to remain stable during the connection process. Usually, the worker manually maintains the stability of the water pipe, and the labor intensity of the worker is relatively high during this process. In response to this technical problem, the present application proposes a hydraulic valve with high stability. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1-3 The present invention provides an embodiment of a hydraulic valve with high stability, comprising:

[0026] Valve body 1, both left and right ends of the valve body 1 are fixedly connected with flange 2, and the side of flange 2 away from the valve body 1 is fixedly connected with a fixing block 7, the outer diameter of the fixing block 7 is smaller than the inner diameter of the fixing ring 10, and the fixing block 7 can be inserted into the fixing ring 10. A circular groove 8 is provided on the outer wall of the end of the fixing block 7 away from the flange 2. The specifications and dimensions of the circular groove 8 are adapted to the steel balls 12. By providing the circular groove 8, a plurality of steel balls 12 can be matched to achieve the effect of limiting the connecting pipe 4, and a sealing ring 9 is fixedly connected to the outer wall of the end of the fixing block 7 away from the flange 2. By providing the sealing ring 9, water overflow at the connection between the connecting pipe 4 and the valve body 1 can be avoided;

[0027] Reference Figure 1-3, wherein, the connecting pipe 4, one end of the connecting pipe 4 close to the valve body 1 is fixedly connected to the flange 2 3, the flange 1 2 and the flange 2 3 are connected by multiple bolts, the outer wall of the connecting pipe 4 is provided with multiple moving grooves 6, the moving groove 6 can provide space for the movement of the moving block 5, a moving block 5 is provided in the moving groove 6, the moving block 5 is fixedly connected to the outer wall of the moving ring 11, and the moving ring 11 can be moved by pulling the moving block 5, and the inner wall of the connecting pipe 4 close to the end of the flange 2 3 is fixedly connected to a fixing ring 10, and the wall thickness of the fixing ring 10 close to the end of the flange 2 3 is greater than the wall thickness of the other end, and the end with the smaller wall thickness can form a match with the connecting pipe 4, thereby providing space for the moving ring 11. The moving ring 11 and the spring 13 provide moving space. The outer wall of the fixed ring 10 away from the end of the flange 2 3 is provided with a spring 13. The moving ring 11 can be reset by the spring 13 to push the multiple steel balls 12 to move inward. One end of the spring 13 is connected to the moving ring 11, and the other end of the spring 13 is connected to the connecting pipe 4. The outer wall of the fixed ring 10 has multiple limiting holes, and the limiting holes are provided with steel balls 12. By moving the multiple steel balls 12, the limiting effect of the connecting pipe 4 can be achieved. The outer wall of the fixed ring 10 close to the flange 2 3 is provided with a moving ring 11. By moving the moving ring 11, whether the multiple steel balls 12 move can be controlled.

[0028] Working principle: When connecting the connecting pipe 4 to the valve body 1, first pull the two moving blocks 5 in the direction away from the flange 2 3. The moving block 5 moves by moving the moving ring 11, and the moving ring 11 compresses the spring 13. Then align the connecting pipe 4 with the fixed block 7 and insert it. The multiple steel balls 12 on the outer wall of the fixed ring 10 are squeezed by the sealing ring 9 and displaced outward, so that the connecting pipe 4 can be connected to the fixed block 7. When passing through the circular groove 8, due to the lack of squeezing of the sealing ring 9, the multiple steel balls 12 can be freely displaced. At this time, release the moving block 5, and the spring 13 pushes the moving ring 11 in the direction close to the flange 2 3, so that the multiple steel balls 12 move inward for a distance, so that the multiple steel balls 12 fall into the circular groove 8 to achieve a locking effect, which is convenient for the staff to fix the flange 2 3 and the flange 1 2 together with bolts.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
