Abstract
The utility model discloses a liquid seal device comprising a liquid accommodating bottle and an exhaust pipe, wherein an opening is formed at the bottom of the liquid accommodating bottle and is sealed through a seal plug; a through hole is formed on the seal plug; and the exhaust pipe penetrates the through hole and is in sealed connection with the inner edge of the through hole. As the liquid accommodating bottle, the exhaust pipe and the seal plug are independent, the assembly and the disassembly are convenient, and corresponding seal plugs can be selected according to the calibers of different reaction bottles; and being made of plastic, the liquid accommodating bottle is elastic, so that the liquid accommodating bottle can not be broken due to collision.
Description
Technical field
The utility model relates to a kind of chemical reaction instrument, relates in particular to a kind of liquid seal device that is used for capping bottle bottleneck.
Background technique
In order to measure the content of titanium dioxide in the pigment, need utilize the aluminum reduction method in the relevant criterion, in reaction bulb, behind adding test object and the reaction reagent,, need liquid sealing pipe be installed at bottle mouth position in order to guarantee the seal of reaction bulb bottleneck.
Referring to Fig. 1; Existing liquid sealing pipe comprises liquid holding bottle 1 and outlet pipe 2, and outlet pipe 2 runs through liquid holding bottle 1 bottom, and outlet pipe 2 is tightly connected with the position of liquid holding bottle 1 pig; Outlet pipe 2 one ends are to extending below, and the other end is positioned at liquid holding bottle 1 and has the bending at top.
Usually liquid holding bottle 1 is the glass material of one with outlet pipe 2, and is frangible when being collided with, and in addition according to the bore of reaction bulb bottleneck, needs the liquid sealing pipe of configure dedicated respectively, causes unnecessary waste.
The model utility content
The utility model provides a kind of highly versatile, and detachable liquid seal device can be used for the fluid-tight of reaction vessel opening.
A kind of liquid seal device comprises liquid holding bottle and outlet pipe, and described liquid holding bottle has bottom opening, and this bottom opening is through sealing plug sealing, and described sealing plug has through hole, described outlet pipe run through this through hole and and through hole in along between be tightly connected.
The shape of outlet pipe can adopt existing technology in the utility model, and an end is to extending below, and the other end is positioned at liquid holding bottle and has the bending at top.
Described sealing plug can adopt rubber or cork.Described liquid holding bottle preferably adopts plastic material.
Described sealing plug is made up of the top and the bottom of integrative-structure, and described top is inserted in the bottom opening of liquid holding bottle, and described bottom is used to stretch into the reaction vessel opening, and reaction vessel is sealed.Described through hole runs through the top and the bottom of sealing plug.
Described bottom is the rounding bench-type, and described top is the cylindrical or truncated cone shape coaxial with the bottom.As preferably, the surface of contact of described top and bottom is a ledge structure, and promptly the diameter of bottom surface, top is less than the diameter of bottom end face, and ledge structure can support the bottleneck of liquid holding bottle just.
The utility model liquid seal device, liquid holding bottle, outlet pipe and sealing plug adopt and divide body structure, are convenient to assembly and disassembly, can change corresponding sealing plug according to different reaction bulb bores.Liquid holding bottle adopts plastic material to have certain elasticity, can avoid being collided with and fragmentation.
Description of drawings
Fig. 1 is the structural representation of existing liquid sealing pipe;
Fig. 2 is the generalized section of the utility model liquid seal device.
Embodiment
Referring to Fig. 2, a kind of liquid seal device of the utility model comprises liquid holding bottle 6 and outlet pipe 3, and liquid holding bottle 6 has bottom opening, and this bottom opening is through sealing plug 7 sealings, and sealing plug 7 has through hole, outlet pipe 3 run through this through hole and and through hole in along between be tightly connected.Outlet pipe 3 one ends stretch into reaction vessel 4 to extending below, and the other end is positioned at liquid holding bottle 6 and has the bending at top.
The bottom is the rounding bench-type, and the top is and coaxial cylindrical in bottom that the surface of contact of top and bottom is a ledge structure, can support the bottleneck of liquid holding bottle 6 just.
In the utility model liquid seal device, liquid holding bottle, outlet pipe and sealing plug adopt and divide body structure, are convenient to assembly and disassembly, can change corresponding sealing plug according to different reaction bulb bores.Liquid holding bottle adopts plastic material to have certain elasticity, can avoid being collided with and fragmentation.
