Abstract
The invention discloses a split type leakage-free joint for subpackaging poisonous solutions in chemical laboratories, and the joint belongs to the field of teaching articles. The joint consists of a liquid inlet connector and a liquid outlet connector; the liquid outlet connector is formed by arranging a liquid outlet switch at the tail end of a liquid outlet glass tube; the outer end of the liquid outlet switch is provided with a transverse bottom-free circular-sleeve-shaped casing head, and the inner wall of the casing head has an abrasive surface; the sidewall of the outer end of the casing head is provided with a rectangular casing opening; the inner end of the inner circular wall surface of the casing head is externally tangent with the outer circular wall surface of the liquid outlet switch at a communicated circular-mouth part; the liquid inlet connector is formed by arranging a mutually-communicated truncated-cone-shaped plug at the tail end of a liquid inlet tube, and the plug can be matched with the casing head by transversely vertically inserting into the casing head; the outer circular wall surface of the plug is an abrasive surface; a liquid inlet switch is arranged in the plug; the outer circular wall surface of the liquid inlet switch is communicated with the outer circular wall surface of the plug in an internal tangent manner; the plug can be matched with the casing head by inserting into the casing head and no leakage happens at contact part of the two abrasive surfaces; and the liquid inlet switch is capable of being communicated with the liquid outlet switch. The split type leakage-free joint is capable of subpackaing poisonous solutions without leakage and pollution to environment.
Description
One, technical field
Chemical laboratory packing venom belongs to realia field with split type without leaky junction, relates to chemical laboratory packing venom joint design, particularly the detachable structure without leaky junction.
Two, background technology
Chemical laboratory packing venom is made joint with sebific duct, and packing finishes rear normal residual venom contaminated air.
Three, summary of the invention
When this product is a kind of chemical laboratory packing venom of invention, not residual venom contaminated environment is split type without leaky junction.
1, technical scheme
Chemical laboratory packing venom is made up of fluid joint and liquid inlet joint without leaky junction with split type, fluid joint is to have a fluid switch at fluid glass tube end, fluid switch outer end has a horizontal vertical round platform snare shape without bottom surface pullover, pullover inwall is frosting, on the sidewall of pullover outer end, there is a rectangle running-on, the inner round mouth place that communicates with fluid switch cylindrical wall of pullover inner circle wall is circumscribed, liquid inlet joint is to have one to communicate and the horizontal vertical pullover Rotary-table shape plug of insertion of can joining at feed liquor glass tube end, plug cylindrical wall is frosting, in plug, there is a feed liquor switch, feed liquor switch cylindrical wall communicates with plug cylindrical wall inscribe, plug can be joined and inserted pullover and two frostings and do not leak, feed liquor switch can interlink with fluid switch.
2, beneficial effect
Fluid jiont treatment is communicated with reservoir, liquid inlet joint is installed and is communicated with sub-bottling, the feed liquor plug of liquid inlet joint precoating vaseline is inserted in fluid joint precoating vaseline pullover, open respectively feed liquor switch and fluid switch and get final product packing venom, after packing completes, shut respectively fluid switch and feed liquor switch, take out feed liquor plug and can realize the contaminated environment without venom leaks.
Four, brief description of the drawings
Fig. 1 be chemical laboratory packing venom with split type without leaky junction sketch.
In Fig. 1: the pullover 5 running-on 6 feed liquor glass tube 7 plug 8 feed liquor switches 9 of fluid joint 1 liquid inlet joint 2 fluid glass tube 3 fluid switches 4.
Five, detailed description of the invention
With reference to accompanying drawing 1, by glass casting system, the fluid glass tube 3 of fluid joint 1 and the feed liquor glass tube 7 of liquid inlet joint 2 are thick 2 millimeters, long 5-10 centimetre, 6 millimeters of interior diameters, fluid switch 4 and feed liquor switch 9 rotating parts be this two pipe of common coupling etc. large cone cylinder body shape standard switch, pullover 5 is thick 2-3 millimeter, the upper and lower circular diameter of internal face and high and plug Shang Xia 8 circular diameter all identical with height, the wide 6-11 millimeter of running-on 6, plug 8 can be joined and inserted pullover 5, high 3.5 centimetres, 3.5 centimetres of bottom great circle φ, 1.5 centimetres of top roundlet φ.
