Description
Technical Field
The utility model relates to a dress liquid ware for in the gas monitoring sampling especially relates to a porous glass board absorption tube dress liquid ware of U type, belongs to environmental detection equipment technical field.
Background
The U-shaped porous glass plate absorption tube has high absorption efficiency and is widely applied to gas monitoring and sampling, but the absorption tube has a unique shape, SO that liquid is not easy to fill in the absorption tube during use, and SO is simultaneously added2、NOXThere is a precise requirement for the volume of the absorption liquid in the sampling of the gas. The general liquid filling method comprises the following steps:
1. the pipette is used to fill the liquid, one person is added from one end and the other person is aspirated from the other end using an ear-washing bulb. The disadvantages are as follows: although the method has accurate liquid filling and is not easy to cause loss, the method is time-consuming, needs two persons to cooperate and wastes manpower.
2. The solution was filled with a syringe. The disadvantages are as follows: the error is big, and improper operation just can have the liquid because of the resistance spill, causes the loss of absorption liquid, not only wastes absorption liquid, and the absorption tube also needs heavy washing or dry, inefficiency.
3. The funnel method is that one latex tube is used to connect the funnel with one absorption tube, and a certain amount of absorption liquid is accurately absorbed and stored in the funnel, and the ear washing ball is used to suck air from the other section. The disadvantages are as follows: time consumption and low efficiency, and the absorption liquid is easy to remain in the latex tube to cause errors.
4. The liquid is filled by a liquid separator. The disadvantages are as follows: although this method can draw the correct volume of liquid, it is also very inefficient because it must be very slow when filling the tubing at one end, resulting in spillage of the liquid as it fills the tubing at the other end, and the ear wash bulb must be used to aspirate the liquid at the other end.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the utility model provides a U type porous glass board absorption tube liquid charging ware, through set up the aurilave at the side of U type porous glass board absorption tube, the aurilave passes through the hose and communicates with the suction port of U type porous glass board absorption tube, left hand operation aurilave release, the liquid can be conveniently filled to the inlet of U type porous glass board absorption tube to instrument such as liquid removal rifle of right hand operation, use convenient operation, the effectual problem of having solved above-mentioned existence.
The technical scheme of the utility model is that: the utility model provides a porous glass board absorption tube of U type dress liquid ware, it includes porous glass board absorption tube of U type and aurilave, and the top of porous glass board absorption tube of U type is equipped with inlet and suction opening, the aurilave is located the side of the porous glass board absorption tube of U type, and the suction opening of the porous glass board absorption tube of U type passes through the hose and is connected with the aurilave.
The lower part of the aurilave is provided with a bottom with an arc-shaped structure, the side wall of the aurilave is provided with a groove matched with the U-shaped bottom of the U-shaped porous glass plate absorption tube, and the U-shaped porous glass plate absorption tube is clamped in the groove.
The hose and the suction port are of a detachable sleeving structure.
The utility model has the advantages that: compared with the prior art, adopt the technical scheme of the utility model, side through at the porous glass board absorption tube of U type sets up the aurilave, and the aurilave passes through the suction opening intercommunication of hose and the porous glass board absorption tube of U type, and left-hand operation aurilave release, the right hand adopt the inlet filling liquid to the porous glass board absorption tube of U type that instruments such as pipetting gun can be convenient, use convenient operation, and the topping up process can alone be accomplished, practices thrift the manpower and improves work efficiency greatly.
