Detailed Description
The embodiment of the integrated mining hydraulic multiple water break protector is described below with reference to the accompanying drawings and specific embodiments.
The water cut-off protector comprises a valve body 1, two layers of main channels 3 which are parallel to each other are arranged on the valve body 1, a water inlet 2 and an oil inlet 5 which are communicated with the main channels 3 are respectively arranged at the left part and the right part of the main channel 3 at the top layer, a water outlet 23 and an oil outlet 22 which are communicated with the main channels 3 are respectively arranged at the left part and the right part of the main channel 3 at the bottom layer, a narrow channel 4 with the diameter smaller than the inner diameter of the main channel 3 is arranged in the middle of the main channel 3, a valve core 9 is arranged in the narrow channel 4, the valve core 9 divides the main channel 3 into a water pressure chamber 6 and an oil pressure chamber 13, the diameter of the valve core 9 in the narrow channel 4 is matched with the inner diameter of the narrow channel 4, a section of a water inlet 11 with the diameter smaller than the inner diameter of the narrow channel 9 is arranged on the valve core 9 in the narrow channel 4, a hydraulic pressure chamber 6, an oil pressure chamber 10 is formed between the small diameter of the valve core 9 and the narrow channel 4, a water pressure chamber 13, a water inlet 18 of the valve core 9, a water pressure chamber 13 is arranged on the narrow channel, a water pressure chamber, a water inlet 18, a water plug 14 is arranged on the left end surface of the narrow channel 13, a water pressure chamber, a water plug 7, a water plug 14 is arranged on the oil pressure plug 7, a water plug 14, a water plug 7, a water plug 14 is arranged on the oil pressure plug, a water plug 14 is arranged on the oil pressure plug, a water plug 7 is arranged on the oil pressure channel, a water plug 7, a water plug 7 is arranged on the oil pressure plug, a water plug 7 plug, a water plug 7 is arranged on the oil pressure channel, a water plug 7 is arranged on the oil pressure plug, a water plug 6, a water plug 7 is arranged on the oil pressure channel, a water plug.
When in use, referring to fig. 1 and 2, pressure water enters the main channel 3 in the valve body 2 from the water inlet 2, acts in the water pressure chamber 6 and generates a rightward hydraulic pressure; the emulsion enters the main channel 3 in the valve body 2 from the oil inlet 5 and is isolated in the oil pressure chamber 13 by the oil pressure sealing plug 12. When the hydraulic chamber 6 is conveyed downwards through the water channel 20 to be filled with pressure water, as the diameter of the hydraulic sealing plug 7 is larger than that of the oil pressure sealing plug 12, the hydraulic sealing plug 7 can push the valve core 9 and gradually apply force to the compression spring 14 under the action of hydraulic pressure, at the moment, as shown in fig. 4, the hydraulic sealing plug 7 is positioned on the right side of the water outlet 23, and the pressure water flows out of the water outlet 15 and is sprayed to an operation part through a spray pipe so as to prevent the generation of sparks. Gradually increasing the water pressure, as shown in fig. 3, pushing the oil pressure sealing plug 12 to move right by the valve core 9, and communicating the oil pressure chamber 13 with the oil channel inlet 16 through the oil pressure communicating chamber 10, as shown in fig. 2, and then allowing the emulsion to enter the lower oil pressure chamber 13 from the oil channel 17; as shown in fig. 4, the spool 9 in the lower stage communicates the oil pressure chamber 13 with the oil outlet 22 through the oil pressure communication chamber 10 in the same operation manner again, and the emulsion is delivered from the oil outlet pipe to the hydraulic motor to provide the operation power.
When the valve core on the upper layer has mechanical failure, the compression spring 4 loses the adjusting function, the oil pressure sealing plug 12 is clamped at the rightmost end position of the oil pressure chamber 12, if the water inlet 2 stops supplying water, since the oil passage inlet 16 is not closed, the emulsion can still be transported from the oil passage 17 to the lower layer, at which time the hydraulic pressure chamber 6 located at the lower layer also loses water pressure, but the compression spring 14 can push the oil pressure sealing plug 12, so that the oil pressure sealing plug 12 moves leftwards to cut off the oil supply of the oil pressure communication chamber 10 to the oil outlet 22, the hydraulic motor stops working, thus realizing the control of the opening and closing of the oil path of the emulsion by the pressure water by utilizing the double water-cut linkage, through the linkage of hydraulic oil or emulsion and shower water, the oil circuit can be opened only when pressure water exists, the hydraulic motor can be started to work, mechanical faults of any one stage are guaranteed, if water is cut off, the oil circuit is disconnected, and the motor stops running or cannot be started.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
