[0011] Beneficial effects

[0012] The utility model provides a pipeline valve for a concrete mixing plant which is convenient for maintenance. Compared with the prior art, the following beneficial effects are achieved:

[0013] 1. In the utility model, through the arranged maintenance flow-blocking assembly, when the valve needs to be maintained, maintenance personnel can respectively rotate the flow-limiting handwheels on the upper surfaces of the concrete mixing plant connecting pipe and the concrete mixing plant discharge pipe, so that the two flow-limiting valves rotate to the horizontal closed state, thereby preventing materials such as water and additives from entering the inside of the valve housing. At this time, materials such as water and additives are discharged into the rear of the concrete mixing plant discharge pipe through the shunt pipeline. In this way, the valve can be maintained without closing the entire pipeline, greatly reducing the shutdown time during maintenance and improving the production efficiency.

[0014] 2. In the utility model, through the arranged maintenance disassembly assembly, after the materials are blocked from passing through the valve housing by the maintenance flow-blocking assembly, by removing the connecting bolts between the connecting flange and the disassembly flange, and then removing the disassembly flange and the pipeline valve wheel, the internal structure of the valve housing can be maintained. Due to the design of the maintenance disassembly assembly allowing for quick disassembly and assembly, the maintenance work can be completed in a relatively short time, reducing the shutdown time of the production line and improving the production efficiency.

Specific implementation manners

[0021] 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. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

The left and right ends of the valve housing 1 are connected to a concrete mixing plant inlet pipe 2 and a concrete mixing plant discharge pipe 3 through flanges. It should be noted that the concrete mixing plant inlet pipe 2 is used to connect to the feeding position of the mixing equipment used in the concrete mixing plant, and materials such as water and additives in the concrete are introduced into the mixing equipment through this pipe. A shunt pipe is connected between the concrete mixing plant inlet pipe 2 and the concrete mixing plant discharge pipe 3. Maintenance blocking components 4 are provided at the intersection positions of the concrete mixing plant inlet pipe 2 and the concrete mixing plant discharge pipe 3 close to the shunt pipeline 6. The maintenance blocking component 4 includes a flow-limiting handwheel 401, a connecting rod 402, a flow-limiting valve 403, a friction gasket 404, and a fixing cylinder 405. The fixing cylinders 405 of the two maintenance blocking components 4 respectively penetrate through the concrete mixing plant inlet pipe 2 and the concrete mixing plant discharge pipe 3. A connecting rod 402 is penetrated through the middle of the fixing cylinder 405. The lower end of the connecting rod 402 is fixedly connected to the flow-limiting valve 403, and the upper end of the connecting rod 402 is fixedly connected to the flow-limiting handwheel 401. A friction gasket 404 is provided at the connection position between the connecting rod 402 and the fixing cylinder 405. The friction gasket 404 is used to increase the friction between the connecting rod 402 and the fixing cylinder 405 to prevent the flow-limiting valve 403 from accidentally rotating under the impact of materials such as water and additives in the concrete.

[0025] During operation, when the valve needs to be maintained, maintenance personnel can rotate the flow-limiting handwheels 401 on the upper surfaces of the concrete mixing plant inlet pipe 2 and the concrete mixing plant discharge pipe 3 respectively, so that the two flow-limiting valves 403 rotate to the horizontal closed state, thereby preventing materials such as water and additives from entering the interior of the valve housing 1. At this time, materials such as water and additives are discharged to the rear of the concrete mixing plant discharge pipe 3 through the shunt pipeline 6. In this way, the valve can be maintained without closing the entire pipeline, greatly reducing the downtime during maintenance and improving production efficiency.

The lower end of the connecting flange 501 is fixedly connected to the upper surface of the valve housing 1. The upper surface of the connecting flange 501 is provided with a disassembly flange 502. A plurality of connecting bolts 503 are arranged through between the connecting flange 501 and the disassembly flange 502.

The upper end of the threaded rod 509 is fixedly connected with a pipeline valve wheel 505. The lower end of the threaded rod 509 is fixedly connected with a flow regulating valve 508. The flow plate 506 is arranged at the central position inside the valve housing 1. A through hole 507 is opened in the middle of the flow plate 506. The left side of the flow plate 506 is fixedly connected to the upper side of the inner wall of the valve housing 1. The right side of the flow plate 506 is fixedly connected to the lower side of the inner wall of the valve housing 1. Flow velocity detectors 7 are arranged on the upper surfaces of one end of the concrete mixing plant connecting pipe 2 close to the valve housing 1 and one end of the concrete mixing plant discharge pipe 3 far from the valve housing 1. After the material passing through the valve housing 1 is blocked by the maintenance and flow blocking component 4, by removing the connecting bolts 503 between the connecting flange 501 and the disassembly flange 502, and then removing the disassembly flange 502 and the pipeline valve wheel 505, the internal structure of the valve housing 1 can be maintained. Due to the design of the maintenance and disassembly component 5 allowing for quick disassembly and assembly, the maintenance work can be completed in a relatively short time, reducing the downtime of the production line and improving the production efficiency.

[0028] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
