Product Description
One. High-pressure sealing needle brief: high pressure pouring machine accessories - high-pressure sealing the needle: It is the principle of using loop fastening pressure. Head of a one-way cut solution under high pressure to push down spray. Rubber ring is only part of the pressure expansion valve, to prevent slurry plastic casing, the diameter of 13mm, 13mm aperture inserted into the grouting hole, the rotating ring compression bolt, compressed rubber casing, the expansion of rubber fixed to the injection grouting mouth plasma hole. (Grouting mouth pressure check valve to open in 0.4KN above, the injection pressure must be greater than this value.) Second, classification and description of high-pressure sealing are currently four types of needles: copper mouth, mouth aluminum, steel mouth , the plastic nozzle, the first three for the ring type fastening pressure. Belonged to the former sealing type, that is filling the mouth of the feed nozzle check valves located in the entrance; after the seal type, which feed the mouth of the check valve in the outlet, depending on the particular situation of choice. Laid before the seal type after a good grouting nozzle can be rotated front to carry out a pressure relief drainage, to be screwed again when filling up; mouth after a good seal type buried, it can not drain the water, but the construction is completed to remove grout mouth processes the next construction. Common part of filling the mouth diameter of the rubber seal 13mm, 14mm drill bit to be with. Use of compact structure 7 ~ 8cm in length to the filling mouth; on the loose structure, the choice of the length of the filling mouth 10 ~ 15cm
Three needle size: A-8 A-10 A -15 A-20 A-25 A-30 A-35 A-40 B -5 B-8
