This utility model relates to the field of three-way plug valve technology and discloses a three-way plug valve, including a three-way valve body and a connecting plate. The connecting plate is disposed above the three-way valve body, and multiple mounting bolts are threadedly connected to the connection between the connecting plate and the three-way valve body. A drive shaft is rotatably connected inside the connecting plate, and the shaft of the drive shaft extends into the interior of the three-way valve body. A valve core is rotatably disposed inside the three-way valve body, and the top end of the valve core is fixedly connected to the bottom end of the drive shaft. When the drive shaft is rotated to switch the passage, the pressure plate rotates with the drive shaft. When the right-angle hole of the valve core aligns with the target passage, the pressure plate contacts one of the pressure sensors and applies pressure. The pressure sensor transmits the pressure signal to the controller through a wire. The controller can feed back the signal to an external control system, realizing accurate detection and feedback of the valve core switching position, ensuring accurate passage switching.

The utility model relates to the technical field of dust removal treatment, and discloses mine dust treatment equipment which comprises a treatment equipment base body, a mechanical angle adjusting device is installed above the treatment equipment base body, and a crank device is installed above one side of the mechanical angle adjusting device. When the device is used, efficient and labor-saving operation can be conveniently achieved through a small gear transmission device, a medium gear transmission device and a large gear transmission device which are internally designed through an arranged mechanical angle adjusting device, the device is of a pure mechanical structure, a small gear is driven through a crank, and the small gear is driven to rotate through a rotating shaft. By means of the multi-stage gear meshing design, the operation torque is remarkably reduced, the adjusting process is easier and more labor-saving, the whole device does not need to be driven by electricity completely, and the angle adjusting device is particularly suitable for being reliably used under the environmental conditions of the open mining industry and the like. The device has the outstanding advantages of simple structure, convenience in maintenance, high adaptability and the like.

This invention relates to the field of power distribution switchgear technology, and particularly to a load switch operating mechanism for a ring main unit, comprising a switch operating shaft, a grounding operating shaft, an energy storage component, and a limit component. The switch operating shaft is coaxially arranged with the switch drive shaft, and a first drive dial is located at its end; the grounding operating shaft is parallel to it above, and a second drive dial is located at its end. The energy storage component is pivotally connected to the switch drive shaft and the grounding operating shaft at both ends, respectively, enabling it to correspondingly perform closing and grounding energy storage and achieve rapid energy release during opening. The limit component includes a first driven dial, a second driven dial, a first limit arm, and a second limit arm. The two limit arms are respectively located above and below the first driven dial, ensuring reliable overshoot and rebound prevention when the switch is in the closed position performing an opening action; and reliable overshoot prevention when opening from the grounding position. When closing, the switch operating shaft rotates forward to unlock and store energy; when opening, it rotates backward to release energy and prevent overshoot and rebound; when grounding, the grounding operating shaft rotates backward to unlock and store energy.

The sensor dismounting device comprises an operating rod set, and the tail end of the operating rod set is provided with a multi-mode dismounting end head assembly; the multi-mode disassembling end head assembly comprises a lever type disassembling part and a torsion type disassembling part; the lever type dismounting part can swing along with the operating rod group to pry up a sensor to be dismounted; the torsion type dismounting part rotates along the plane where the sensor is located to screw the sensor to be dismounted. The lever type dismounting part can swing along with the operating rod group to pry up a sensor to be dismounted; the torsion type dismounting part rotates along the plane where the sensor is located to screw the sensor to be dismounted. The two modes share the same operating rod set, the operation modes can be switched according to the space condition only through single-time insertion, and the requirement for repeatedly adjusting the angle of a traditional tool is thoroughly eliminated. In an engine compartment and other high-temperature environments, an operator operates away from a heat source through the operating rod set, limbs are prevented from making contact with the metal surface at the temperature of 150 DEG C or above, and therefore safety is improved.
