Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to an agricultural three-dimensional shut-off valve. Background Art

[0002] The pipes used for farm irrigation usually use canvas hoses. Sometimes, it is necessary to install a shutoff valve on the pipe. The traditional shutoff valve requires the pipe to be cut off and then connected at both ends of the shutoff valve. This solution has some problems in actual use. First, it is inconvenient to install and requires professional tools to cut and connect. Second, it will cause irreversible damage to the pipe. If the shutoff valve is removed at one end, the pipe will be damaged. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an agricultural three-dimensional shut-off valve, which can be installed at any section of a soft pipe without destroying the pipe. It is easy to disassemble and assemble, and the shut-off effect is comparable to that of a traditional shut-off valve. It is more economical and reliable. The extruded part can also be driven by a manual wrench or a motor, which is more labor-saving.

[0004] The technical solution adopted by the utility model to solve the technical problem is: comprising a flow cut-off frame, an extrusion member and a driving member;

[0005] The driving member comprises a screw, an outer cylinder and a rotating head, the inner end thread of the screw is adapted to the inner end of the outer cylinder, the outer end of the screw is rotatably matched with the intercepting frame, and the outer end of the screw is provided with a driven bevel gear;

[0006] The rotating head is rotatably matched with the intercepting frame, the rotating head is provided with a driving bevel gear meshing with the driven bevel gear, and the rotating head is provided with a twisting head with a prism structure or a prism hole structure;

[0007] The intercepting frame is provided with an intercepting window, the extruding member is provided in the intercepting window, the driving member drives the extruding member to sweep and close the intercepting window relative to the intercepting window, and the intercepting window is provided with an openable and closable notch.

[0008] When this solution is used, the gap is opened, and then the soft pipe is placed in the interception window through the gap, and then the gap is closed, and then a wrench or motor is used to adapt to the screw head to drive the rotating head to rotate. The rotating head drives the screw to rotate through the active bevel gear and the driven bevel gear. The screw is adapted to the outer tube thread, so the rotation of the screw will drive the outer tube to extend or shorten relatively, thereby pushing the extrusion piece to sweep and close the window in the interception window, thereby achieving the extrusion of the soft pipe and achieving the interception effect. The gap can be directly put on from the position where the interception valve needs to be set on the soft pipe, without the need to set it from the end of the pipe, and the installation is very convenient.

[0009] Preferably, slide rails are provided on both sides of the intercepting window, and both ends of the extrusion piece are slidably matched with the slide rails, so as to facilitate the extrusion piece to sweep through the intercepting window.

[0010] Preferably, the slide rail is a slide groove arranged inside the intercepting window, so that the extrusion piece slides downward more smoothly.

[0011] Preferably, the screwing head is a hexagonal screwing through hole, so that it can be driven to rotate better by an external hexagonal wrench or a drill bit, and the screwing head will not protrude outward.

[0012] Preferably, it comprises an electric drive structure, wherein the electric drive structure comprises an outer frame, a motor and a screw rod;

At the same time, the cooperation of the spring and the screw can achieve a clutch-like effect. Specifically, the external hexagon screwing rod is adapted to the internal hexagon screwing hole by rotating the screw. At this time, the internal hexagon screwing hole can be driven to rotate normally. Similarly, the screw is rotated in the opposite direction. With the cooperation of the spring, the external hexagon screwing rod and the internal hexagon screwing hole are separated, and the motor cannot drive the internal hexagon screwing hole to rotate.

[0015] Preferably, the intercepting window comprises a side bar, a top bar and a bottom bar, the upper ends of the two side bars are connected to the two ends of the top bar, the lower ends of the side bars are connected to the two ends of the bottom bar, the slide rail is arranged at the lower section of the side bar, and the driving member is arranged at the top bar.

The outer end of the screw 9 is rotatably matched with the intercepting frame. A driven bevel gear 12 is arranged at the outer end of the screw 9.

[0031] The rotating head 11 is rotatably matched with the intercepting frame, and the rotating head 11 is provided with a driving bevel gear 13 meshing with the driven bevel gear 12, and the rotating head 11 is provided with a twisting head 11 with a prism structure or a prism hole structure;

[0032] The intercepting frame is provided with an intercepting window 1, the extruding member 8 is provided in the intercepting window 1, the driving member drives the extruding member 8 to sweep and close the intercepting window 1, and the intercepting window 1 is provided with an openable and closable notch.

[0033] When this solution is used, the gap is opened, and then the soft pipe 7 is placed in the interception window 1 through the gap, and then the gap is closed, and then a wrench or a motor is used to adapt to the screw head 11 to drive the rotating head 11 to rotate, and the rotating head 11 drives the screw 9 to rotate through the active bevel gear 13 and the driven bevel gear 12. The screw 9 is thread-matched with the outer tube 10, so the rotation of the screw 9 will drive the outer tube 10 to extend or shorten relatively, thereby achieving the action of pushing the extrusion member 8 to sweep and close the window in the interception window 1, thereby achieving the extrusion of the soft pipe 7 and achieving the interception effect. The use of the gap can be directly put on from the position where the interception valve needs to be set on the soft pipe 7, without the need to set it from the end of the pipe, and the installation is very convenient.

Specifically, the screw 18 is rotated to adapt the external hexagon screwing rod 15 to the internal hexagon screwing hole. At this time, the internal hexagon screwing hole can be driven to rotate normally. Similarly, the screw 18 is rotated in the opposite direction. With the cooperation of the spring 16, the external hexagon screwing rod 15 is separated from the internal hexagon screwing hole, and the motor 14 cannot drive the internal hexagon screwing hole to rotate.
