Description

Technical Field

[0001] The utility model relates to the technical field of cement conveying and pouring, in particular to a stop valve for cement conveying. Background Art

[0002] Cement is a powdery, hydraulic, inorganic cementitious material. It becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly bind materials such as sand and stone together. As an important cementitious material, it is widely used in civil engineering, water conservancy, national defense and other projects.

[0003] In the prior art, when cement pouring needs to be stopped during the process of conveying and pouring, it is usually controlled from the cement conveying source. This requires the worker who controls the pouring head to first give a signal to the cement conveying source and then shut it down. The control is very inflexible and inconvenient to use. Utility Model Content

[0004] The utility model aims to provide a stop valve for cement transportation, which has the characteristics of simple and convenient operation, time-saving and labor-saving, and more flexible opening and closing control than the traditional one which controls the opening and closing from the transportation source.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stop valve for cement transportation, comprising a valve cylinder, an outer wall of the valve cylinder is provided with a valve plate groove, the outer wall of the valve cylinder is movably connected to the valve plate through a hinge seat, a connecting rod is fixedly connected to the lower part of the outer wall of the valve cylinder, the other end of the connecting rod is movably connected to a movable plate, the other end of the movable plate is fixedly connected to a swivel seat, and the outer wall of the swivel seat is rotatably connected to a receiving box.

[0006] In order to facilitate closing the valve, as a preferred stop valve for cement transportation of the utility model, the valve plate and the valve plate groove are sealed and movably connected.

[0007] For more convenient use, as a preferred stop valve for cement transportation of the utility model, the outer wall of the valve cylinder is fixedly connected to the main rod, and the outer wall of the valve plate is fixedly connected to the auxiliary rod.

[0008] In order to facilitate pouring out the cement in the receiving box, as a preferred flow-stop valve for cement transportation of the utility model, a handle is fixedly connected to the outer wall of the receiving box.

[0009] In order to facilitate the connection with the cement delivery pipe, as a preferred flow-stop valve for cement delivery of the utility model, the top end of the valve cylinder is fixedly connected with a connecting head.

[0010] In order to lock and fix the movable plate, as a preferred stop valve for cement transportation of the utility model, the outer wall of the movable plate is threadedly connected with a fixing bolt.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] When the stop valve is in use, the connector at the top of the valve cylinder is connected to the external cement delivery pipe, and cement pouring can be carried out. When pouring cement, the valve plate is opened and located outside the valve cylinder, and the valve cylinder penetrates, so as to facilitate cement pouring. At the same time, the receiving box is located on the side of the valve cylinder, which does not affect the normal pouring work. When pouring needs to be stopped, it is only necessary to drive the valve plate to move around the hinge seat through the auxiliary rod, so that the valve plate is plugged into the inside of the valve plate groove, and the valve plate coincides with the center of the valve cylinder, so that the valve cylinder is closed through the valve plate to stop the delivery of cement. The operation is simple and convenient, saving time and effort, and more flexible than the traditional control of opening and closing from the delivery source;

[0013] When the valve plate is closed, first rotate the receiving box through the swivel seat so that the receiving box is located directly below the valve cylinder. In this way, during the transfer to the next pouring point, the receiving box can receive a small amount of leaked cement to avoid waste. After transferring to the next pouring point, rotate the receiving box to the side again and open the valve plate. When the receiving box is full, loosen the fixing bolts and then drive the entire receiving box to move through the movable plate, so that the collected cement can be discharged. The operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
