Detailed Description
The invention is further described below with reference to the accompanying drawings:
the embodiment provides a material inlet valve structure of a pneumatic conveying pump, as shown in fig. 1, comprising a housing 100 and a valve core assembly.
The inside of the casing 100 is a material passage 110 penetrating through both ends of the casing 100, a sealing plate accommodating chamber 120 is provided in the material passage 110, and the inner diameter of the sealing plate accommodating chamber 120 is larger than that of the material passage 110. The material passage 110 and the sealing plate accommodating chamber 120 form a step shape, and the inner wall of the sealing plate accommodating chamber 120 close to one side of the material passage 110 is a sealing surface. The inner wall of the material passage 110 is provided with a valve core mounting seat 130 protruding and abutting against the sealing plate accommodating chamber 120.
The cartridge assembly is mounted to the cartridge mount 130 and includes a seal plate 210, a push rod 220, and a rotary rod 230. The sealing plate 210 is disposed in the sealing plate receiving cavity 120. The sealing plate 210 has an outer diameter greater than an inner diameter of the material passage 110 and is provided at one side thereof with a sliding rod 211. The other end of the sliding rod 211 slidably penetrates through the valve core mounting seat 130 near the sealing plate accommodating cavity 120. One end of the push rod 220 slidably penetrates through the valve core mounting seat 130 and is connected with one end of the sliding rod 211 penetrating through the valve core mounting seat 130, and the other end of the push rod is connected with the inside of the valve core mounting seat 130 through threads 222. The push lever 220 is also provided with a worm gear 221. The rotating rod 230 has one end disposed outside the housing 100 and the other end rotatably penetrating the housing 100 and extending into the valve core mounting seat 130. One end of the rotating rod 230 extending to the inside of the valve core mounting seat 130 is provided with a worm 231 engaged with the worm wheel 221, so that the rotating rod 230 drives the sealing plate 210 to cover the material channel 110 or leave the material channel 110 when rotating.
The utility model discloses a when pneumatic conveyor pump material inlet valve structure used, rotary rod 230 was rotatory, and worm 231 drives worm wheel 221 and rotates to it follows the rotation to drive catch bar 220. When the push rod 220 is rotated by the screw thread 222 at one end of the push rod 220, the push rod 220 also advances and retreats. The forward and backward movement of the push rod 220 drives the sealing plate 210 to cover the material channel 110 or leave the material channel 110, thereby realizing the opening and closing of the valve. The sealing plate 210 covers the material passage 110 and abuts against the sealing surface of the sealing plate accommodating cavity 120 to close the valve. The valve is opened when the valve leaves the sealing surface. The sealing position of the sealing plate 210 and the sealing surface can not damage the valve due to the titanium concentrate entering, so that the sealing performance of the valve is not affected.
Further, an organ shield 213 is disposed on one side of the sealing plate 210 close to the valve element mounting seat 130, and the other end of the organ shield 213 is connected to the valve element mounting seat 130. The organ protection cover 213 prevents the material from entering the valve core mounting seat 130 to damage the valve, and simultaneously prevents air from leaking from the valve core mounting seat 130, thereby further ensuring the sealing property.
Further, one end of the sliding rod 211 penetrating through the valve core mounting seat 130 is ball-hinged to one end of the push rod 220 slidably penetrating through the valve core mounting seat 130. This arrangement allows the seal plate 210 not to follow the rotation when the push rod 220 rotates.
Further, a sealing ring 212 is disposed on a side of the sealing plate 210 close to the material passage 110. The sealing ring 212 is arranged to enable the sealing performance of the valve to be stronger.
Further, one end of the rotating lever 230 disposed outside the housing 100 is provided with a rotating handle 232. It is convenient to screw the rotating rod 230.
The above embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
