Description

Technical Field

[0001] The utility model belongs to the technical field of reversing ball valves, in particular to a stop reversing ball valve. Background Art

[0002] The reversing ball valve is a commonly used valve body, which is mainly composed of a valve body, a ball, and a seal. Its working principle is to use the rotation of the ball to switch the flow direction of the medium. When the valve is in the closed state, the ball will contact the valve seat to form a seal; when the valve is in the open state, the medium can pass through the ball freely;

[0003] During the use of the reversing ball valve, the ball rotation is partially controlled manually. The control is operated by a handle, but the existing handle is usually set horizontally with the valve body. After the adjustment is completed, it is easy to change the angle of the valve core if it is accidentally touched, thereby affecting the flow of the medium. For this reason, a stop reversing ball valve is proposed. Utility Model Content

[0004] The utility model aims to provide a stop reversing ball valve, which utilizes the positioning block to be stuck with the positioning groove, thereby preventing the driving block and the handle from rotating, improving the stability of the valve core, improving the stability of the medium flow, and at the same time, by lowering the positioning pin and inserting it into the jack, and then locking the top screw, the driving block can be fixed, preventing the valve core from moving during transportation, and solving the existing technical problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] A stop reversing ball valve comprises: a valve body, a liquid inlet pipe is installed on one side of the valve body, liquid outlet pipes are installed on both sides of the valve body, the liquid outlet pipes are located on both sides of the liquid inlet pipe, a valve seat is installed in the valve body, a valve core is rotatably connected in the valve seat, a valve stem is fixedly connected to the top of the valve core, and the valve stem rotates through the valve body;

[0007] The top of the valve stem is fixedly connected to a driving block, one side of the driving block is rotatably connected to a handle, the bottom of the handle is fixedly connected to an extension block, the bottom of the extension block is fixedly connected to a plurality of positioning blocks, the top of the valve body is fixedly connected to an annular positioning disk, the surface of the positioning disk is provided with a plurality of positioning grooves used in conjunction with the positioning blocks, and the handle is rotatable so that the positioning block and the positioning groove can be stuck together during use of the product, thereby preventing the driving block and the handle from rotating, thereby improving the stability of the valve core and the stability of the medium flow.

[0008] As a further solution of the utility model, a mounting block is fixedly connected to one side of the driving block, and a spring is fixedly connected between the mounting block and the handle, and the spring increases the stability of the handle.

[0009] As a further solution of the utility model, a top block for limiting the handle is fixedly connected to the surface of the mounting block, and the top block is used to limit the handle to facilitate people's operation.

[0010] As a further solution of the utility model, a penetrating locating pin is inserted into the top of the driving block, and a top screw for fixing the locating pin is threadedly connected to one side of the driving block. A socket for cooperating with the locating pin is provided on the surface of the valve body. When the valve body is not in use or is being transported, the locating pin can be inserted into the socket by lowering it, and then the top screw can be locked, thereby fixing the driving block to prevent the valve core from moving during transportation.

[0011] As a further solution of the utility model, sealing gaskets are arranged between the liquid inlet pipe, the liquid outlet pipe and the valve body.

[0012] As a further solution of the utility model, the top of the valve body is provided with a plurality of through holes for fixing the valve body.

[0013] In this application, when it is necessary to reverse the direction of the medium, the handle is lifted upward, and the handle drives the extension block and the positioning block to move upward, thereby causing the positioning block to disengage from the positioning groove on the positioning disk, and then the drive block is rotated by the handle, and the drive block drives the valve stem to rotate, and the valve stem drives the valve core to rotate, thereby changing the medium flow direction or closing the valve body. After the adjustment is completed, the handle is released, and the handle is reset under the action of the spring, so that the positioning block and the positioning groove are stuck together, thereby preventing the drive block and the handle from rotating, thereby improving the stability of the valve core and the stability of the medium flow. When the valve body is not in use, the positioning pin is inserted into the socket, and then the top screw is locked, so that the drive block can be fixed to prevent the valve core from moving.

[0014] The embodiments of the present invention have the following beneficial effects:

[0015] In the utility model, the handle can be rotated, so that when the product is in use, the positioning block and the positioning groove can be locked together, thereby preventing the driving block and the handle from rotating, thereby improving the stability of the valve core and the stability of the medium flow;

[0016] In the utility model, by installing the positioning pin on the driving block, when the valve body is not in use or in transportation, the positioning pin can be inserted into the insertion hole by putting it down, and then the top screw can be locked, so that the driving block can be fixed to prevent the valve core from moving;

[0017] In the utility model, the positioning block is clamped with the positioning groove to prevent the driving block and the handle from rotating, thereby improving the stability of the valve core and the stability of the medium flow. At the same time, by lowering the positioning pin and inserting it into the jack, and then locking the top screw, the driving block can be fixed to prevent the valve core from moving during transportation.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
