The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
As shown in Figures 1 to 4, the atomization mechanism that is used for mine, comprise the water pipe 7 that ball valve 14 is installed, described water pipe 7 includes water lines 5 and outlet pipeline 6, described outlet pipeline 6 is provided with water spray district 8, described ball valve 14 comprises and is used to control the valve rod 12 that ball valve opens and closes that be separately installed with pulley 4 on the described entry pipeline 5 He on the outlet pipeline 6, the pulley of installing on the above-mentioned outlet pipeline 64 is positioned at the outside of described water spray district 8 away from ball valve 14 1 ends; The valve rod 12 of described ball valve 14 is provided with and is used to control the handle 9 that valve rod 12 rotates, the pulley on the above-mentioned entry pipeline 5, and pulley on the outlet pipeline 6 and handle 9 are positioned at water pipe 7 homonymies; Also comprise rope 1, described handle 9 links to each other with the initiating terminal of rope 1, the tail end of described rope 1 is walked around the pulley on pulley and the entry pipeline 5 on the outlet pipeline 6 successively and is linked to each other with the initiating terminal of rope 1, forms the closed-loop path structure 3 that is used to drive the rotation of handle grip ovable valve stem that cooperates with above-mentioned pulley rolling.At present, general ball valve all comprises a valve rod that is used to control valve core movement, by the rotating band movable valve plug rotation of valve rod, and then the switching of realization ball valve, above-mentioned handle is installed on the valve rod, rotates by swing handle actuatable valve bar, and then realizes the switching of ball valve.Adopt said structure, by rope for traction, can drive handle and rotate, and then drive the valve rod rotation, realize the switching of ball valve.In addition, in order to reduce the resistance that runs into when the rope for traction, the part on the described closed-loop path structure 3 between the pulley on pulley on the outlet pipeline 6 and the entry pipeline 5 is a tractive unit 2, the axially parallel of described tractive unit 2 and water pipe 7.In addition, above-mentioned rope can be preferably nylon rope for wire rope etc.
During use, when the workman from outlet pipeline 6 when entry pipeline 5 directions are advanced, can spur tractive unit 2 earlier, impel handle 9 clockwise directions to rotate, the rotation of handle 9 can drive valve rod and rotate, and then control ball valve 14 is closed, at this moment, water spray district 8 does not have the water smoke ejection, because the pulley of installing on the outlet pipeline 64 is positioned at the outside of described water spray district 8 away from ball valve 14 1 ends, so the workman can close ball valve by tractive unit before entering the water spray district, when treating that the workman runs near the entry pipeline 5, can spur tractive unit 2 and drive handle 9 rotation counterclockwise, and then impel ball valve 14 to open again, the district 8 that sprays water this moment begins to spray water smoke; When the workman advances in the other direction, promptly from entry pipeline 5 when outlet pipeline 6 directions are advanced, can spur tractive unit 2 earlier, handle 9 clockwise directions are rotated, ball valve 14 are closed, treat that the workman passes water spray district 8 after, by tractive unit 2 handle 9 is counterclockwise rotated again, ball valve 14 is opened once more.
In order to reduce rocking that handle takes place in rotation process, it is smooth and easy that handle is rotated, and on the basis of the above, also comprises guiding device, and described handle 9 is positioned at guiding device.Can limit the motion track of handle by guiding device, handle is moved in guiding device, thereby can reduce rocking that handle takes place in rotation process, help handle and rotate smooth and easy.Above-mentioned guiding device can be structures such as framework, gathering sill, preferred implementation is: as shown in Figures 1 to 4, described guiding device comprises two guide strips 11 that are installed on the described water pipe 7, and the plate face of above-mentioned two guide strips leaves gap 13 relatively and between two guide strips.By guide strip, the motion track of handle can be limited in the gap between the guide strip, promptly rotate in the gap of handle between guide strip.
In addition, when the workman by the pulled by cable handle with the ball valve complete opening after, if the water flow pressure in the water pipe 7 is bigger, when then by the pulled by cable handle ball valve being closed again, the resistance that runs into is bigger, be not easy to ball valve is closed, and, in daily use, do not need the ball valve complete opening yet, ball valve is in half-open position can satisfy instructions for use, therefore, in order to overcome above-mentioned deficiency, be provided with two position limiting structures 10 that are used to limit handle 9 movement travels in the described guiding device, one of them position limiting structure is corresponding with the full close position of ball valve 14, another position limiting structure is corresponding with the half-open position of ball valve 14, promptly be limited between full close position and the half-open position by the movement travel of two position limiting structures with handle, the half-open position of ball valve is half corresponding position of the maximum open amount of ball valve, and the full close position of ball valve is the position that ball valve is closed.Adopt said structure, during by the pulled by cable handle, at most ball valve is opened into half-open position, ball valve can be closed fully.The embodiment of above-mentioned position limiting structure has multiple, can be column structure or cube structure etc.For example, as shown in Figure 3 and Figure 4, above-mentioned guiding device is under the situation of two guide strips 11, is connected with two position limiting structures 10 between above-mentioned two guide strips 11, in the gap 13 of described handle 9 between two guide strips and between two position limiting structures 10.
