Abstract
The invention relates to a quickly mounted middle-pressure joint for air-conditioner terminal heat exchanger water pressure testing equipment. The air-conditioner terminal heat exchanger water pressure testing equipment widely adopts threaded joints, a worker needs to place a heat exchanger onto a worktable when in water pressure test, the heat exchanger is manually connected with a water inlet and outlet threaded joint, the water inlet and outlet threaded joint is screwed on the heat exchanger, sealing property of a joint is not easy to be guaranteed, labor intensity of the worker is high, and work efficiency is low. By the aid of the quickly mounted middle-pressure joint, when the heat exchanger is in water pressure test, a movable pulling arm is placed down to hook the bottom end of a water flow distributor, a handle is pushed so that a slide sleeve drives the pulling arm to move on a joint body, an end surface of the water flow distributor is squeezed with a sealing rubber ring, a sealing requirement under pressure is guaranteed, simultaneously, labor intensity of the worker is reduced, and work efficiency is increased.
Description
Technical field
The present invention relates to air conditioning terminal heat exchanger hydrostatic test equipment and use connection set, particularly relate to crimp head in a kind of special-purpose fast-assembling.
Background technique
At present, air conditioning terminal heat exchanger hydrostatic test equipment extensively adopts inipple, needs the workman that heat exchanger is put on the worktable when carrying out the hydrostatic test; Manual connection water inlet and outlet inipple is also screwed; The joint sealing is difficult for guaranteeing that labor strength is big, inefficiency.
Summary of the invention
For overcoming the drawback of air conditioning terminal heat exchanger hydrostatic test equipment inipple; The invention provides crimp head in a kind of special-purpose fast-assembling; Rely on workman's driving handle that the tension device moving-coil is rotated to an angle, can make torque arm drive the sealing rubber ring extruding of crimp head in water distributor end face and the fast-assembling, effectively guarantee the joint sealing; Alleviate labor strength simultaneously, increase work efficiency.
The technical solution adopted for the present invention to solve the technical problems is: adopt crimp head in a kind of special-purpose fast-assembling; When heat exchanger carries out the hydrostatic test; Through activity torque arm 1 is put down, hook water distributor 2 bottoms, driving handle 5 makes sliding sleeve 7 drive torque arm 1 and on fittings body 10, moves; Realize the extruding of water distributor 2 end faces and sealing rubber ring 3, guaranteed the seal request under the pressure.
When heat exchanger carried out the hydrostatic test: open torque arm 1, heat exchanger is put on the worktable, heat exchanger water distributor 2 end faces are contacted with the sealing rubber ring 3 of crimp head in the fast-assembling, put down torque arm 1, water distributor 2 bottoms were hooked in torque arm 1; Driving handle 5 rotates to an angle tension device 4 moving-coils; Utilize the spiral upward stroke of tension device 4 tapered rollers and the effect that thrust-bearing 6 reduces the end face friction; Make sliding sleeve 7 drive torque arm 1 and on fittings body 10, move, realize the crush seal of water distributor 2 end faces and sealing rubber ring 3; Spring 8 is in the pretension compressive state all the time; Nut 9 is used for the pretension compressive force of Regulation spring 8; After the hydrostatic test was accomplished, pulling handle 5 rotated to an angle tension device 4 moving-coils, made sliding sleeve 7 drive torque arm 1 and on fittings body 10, moved, and opened torque arm 1, removed heat exchanger, promptly accomplished heat exchanger hydrostatic test circulation.
The invention has the beneficial effects as follows: replace inipple with crimp head in the fast-assembling, rely on the extruding of the sealing rubber ring of crimp head in water distributor end face and the fast-assembling, effectively guarantee the joint sealing, alleviate labor strength simultaneously, increase work efficiency.
