in the pneumatic valve is a fluid conveying system control unit, a backflow, river closure, adjusting and throttling send flow, preventing backflow, or relief pressure relief, and other functions. Pneumatic valves for liquid transportation, small enough to be used in the shuttle's tiny pneumatic valve, big to 10 tons of pneumatic valve industry. Pneumatic valve and durable in the medium, such as steam, water, air and other fluid; Pressure can range from low pressure to the ultra-high pressure; From operating temperature ℃ ultra-low temperature to ℃ high temperature. In the process of delivery, due to the medium temperature, pressure, corrosion, vibration and internal manufacturing defects, the influence of the production process will inevitably appear leakage phenomenon. In the type of pneumatic valve leakage, the most common major is pneumatic valve is leaking, pneumatic valve is leaking plugging in two ways. 。 Direct drilling method for pneumatic valve cavity wall thickness of the thicker, more than mm but in dynamic conditions using note jeju type pressure leak sealing technology, can be directly in the pneumatic valve stuffing box opening on the wall of injecting hole operation. Operation, such as conditional, dealing with the packing box of the outer wall thickness, check the other defects. First in the pneumatic valve packing box of the outer wall place, this place should be conducive to drill, or use the online leak sealing head installed. Chooses little bit out of a concave nest, according to the size of the pneumatic valve, select MM drill bit drilling, drilling drilling can choose explosion-proof electric drill or pneumatic drill, also can choose charging explosion-proof drill, very convenient. Don't drill holes through. - MM, withdrawing bit, by M M or tap tapping threads. After the tapping screw thread process, the injecting special cock pneumatic valve twist, the injecting special cock pneumatic valve core is turned to the open position, with diameter ~ MM long screw drill bit stuffing box wall drill through the rest of the pneumatic valve, then medium leakage along the drill grinding direction outside spray hurt or damage to the drilling machines. Drill holes can be used before a panel, board in front of the drill, so as not to hurt. After the drill holes, pulled out a bit, the cock pneumatic valve core is placed in the closed position, the leakage of medium cut, so that it can connect note to gun. Nothing more than to leak cavity continuous tears of glue, leak leakage, namely stop injecting, rotary pneumatic valve handle, try a few times more, don't leak, plugging success. 。 Belt clamp plugging leakage method of pneumatic valve packing chamber wall thickness thin, less than MM, on the wall if not safe, 2 it is tapping is difficult, only a few thread, strength is not enough, in this case with auxiliary fixture method is used to leak. The jig is not leak, but for supplementary role. Clip on the outside of the stuffing box, so the curve should be in conformity with the pneumatic valve wall radian, post as tight as possible; If not, can be placed in the joint plane some metal rubber, adhesive glue can also be, as long as the clamp on the thread for M or M, fixture after fixed good, can through wall thickness of stuffing box with a drill. G shape fixture and land treatment of stuffing box leaking special tools, currently on the market have special fixture, models varied, as can choose not to fixture, come to operate. To choose more appropriate fixture, the walls of the pneumatic valve packing box, with a little bit must be a hole, scored the fixture, the positioning hole reaming, until like fixture head of eye socket, and then use the MM diameter drill holes, MM not drilled through. Mount fixture, and then the rest with long bit MM thick wall drill, which leads to the leakage of medium, fitted with special cock pneumatic valve and injecting spear, injecting, plugging end.
