The mechanism comprises a blockage device and a block, wherein the blockage device is used for placing the block in a flange blockage seat on a fitting and comprises a shell, a transmission rod, a lifting device, a separating and connecting device and a blockage connecting box; the transmission rod is arranged in the shell; the lifting device is used for lifting the transmission rod; the separating and connecting device is used for separating and connecting the block; the blockage device connecting box is fixedly connected with the shell and is provided with a monitoring device for monitoring the blockage movement of the block; the monitoring device comprises a camera, a fixed seat and monitoring equipment; the camera is arranged in the blockage connecting box; the fixed seat is used for fixedly arranging the camera; the monitoring equipment is connected with the camera. The visual pipe fitting blockage mechanism realizes pipeline blockage from inside to outside, a process for punching in the blockage seat and the labor are saved, blockage is performed under a visual condition, the mechanism is safer and more reliable, and the risk that gas leaks from a screw hole is avoided.

The invention provides an integrated air compressor which comprises a machine body, a first-stage cylinder, a second-stage cylinder, a third-stage cylinder, a fourth-stage cylinder, a first-stage gas cooler, a second-stage gas cooler and a combined cooler. The first-stage cylinder, the second-stage cylinder, the third-stage cylinder and the fourth-stage cylinder are fixedly connected with the machine body and distributed in an X shape. The first-stage gas cooler, the second-stage gas cooler and the combined cooler are fixedly connected with the machine body, the first-stage gas cooler is arranged between the first-stage cylinder and the fourth-stage cylinder and in a neutral position, the second-stage gas cooler is arranged between the second-stage cylinder and the third-stage cylinder and in a neutral position, and the combined cooler is arranged between the third-stage cylinder and the fourth-stage cylinder and in a neutral position. The high-pressure gas leakage danger caused when pipelines (including gas paths and cooling water paths) between stages on the air compressor vibrate excessively and are pulled broken can be effectively avoided, and the integrated air compressor has the outstanding advantages of being high in integrity, high in space utilization rate, little in vibration, low in work noise and the like.

The invention discloses an endoscope fluid switch-over device. An air inlet, an air outlet and an air port are formed in a valve body; a first coil is arranged in a mode of surrounding the exterior of one end of a valve element, and a second coil is arranged in a mode of surrounding the exterior of the other end of the valve element; and a first seal ring, which is used for blocking the air inlet or the air outlet, and a second seal ring, which is used for blocking the air port, are arranged on the valve element. The invention also discloses an endoscope, wherein the endoscope comprises a head end, an inserting part, an operating part, a light-guide part and a light source part; and the fluid switch-over device is located within the light source part. The fluid switch-over device provided by the invention is simple and compact in structure, small in volume, easy for assembling, low in production cost, high in sensitivity and good in reliability; by arranging the fluid switch-over device in the light source part, overall dimensions of the operating part can be effectively diminished and the weight of the operating part can be reduced, so that the endoscope is more convenient and labor-saving to operate; and meanwhile, by completely isolating gas conveying and water conveying actions, the danger of water conveying leakage is prevented, and influence to other electrical elements due to water leakage is avoided; therefore, the endoscope is safe and reliable.

The invention relates to a starting emission reduction method for an ethene device. The method comprises the following steps: first, an ethene and propylene refrigeration system is started and a refrigerating capacity is supplemented for cold box precooling; second, the cold box precooling is started; third, total reflux of an ethene rectifying tower, a propylene rectifying tower and an ethane removing tower is established; fourth, a cracking furnace is started; fifth, a cracked gas compressor is started; sixth, a subsequent device is started and starting of the ethene device is finished. Because the cold box is subjected to cooling before formal feeding, the product qualified time of the cold box is shortened greatly, the cooling process of the cold box is controllable, and leakage dangers are avoided. Through establishment of total reflux of a low-temperature depropanization tower, the total qualified time of a high-low-pressure depropanization tower is shortened. Because natural gases are introduced to supplement the feed of the compressor, the number of starting feeding cracking furnaces is decreased, and therefore the whole discharge capacity of torches is reduced.
