Technical Field
The utility model belongs to the technical field of the vacuum sampling technique and specifically relates to a lithium bromide unit solution vacuum sampling ware can gather the lithium bromide solution in with the unit through the sample thief and observe.
Background
A lithium bromide refrigerator is called a bromine refrigerator for short, and is an absorption refrigerator commonly used in the world at present. In vacuum state, the lithium bromide absorption refrigerator uses water as refrigerant and lithium bromide water solution as absorbent to prepare low temperature water above 0 deg.C, and is mainly used in central air conditioning system. The lithium bromide refrigerator uses the characteristic that the boiling point of water is lower (only 4 ℃) in a high vacuum state to refrigerate (uses the latent heat of boiling of water).
The main structure of the lithium bromide absorption refrigerator is made of iron material, and the lithium bromide solution itself has strong corrosivity to metal, after the solution is uninterruptedly evaporated, condensed and circulated in the cavities of the evaporator, absorber, solution pump, pipeline and other circulating systems in the refrigerator set, the solution is doped with a large amount of various impurities, such as iron filings, copper filings, various compounds and solid impurities, etc., so that the solution becomes turbid, the water absorbing capacity of the refrigerator set is greatly reduced, and the refrigerating effect of the refrigerator set is reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model discloses a lithium bromide unit solution vacuum sampler can adopt the mode of vacuum sampling, gathers out the lithium bromide solution in the unit from the operation unit and is used for observing wherein impurity that adulterates whether exceeds standard to whether the decision is more renewed lithium bromide solution.
The utility model discloses a specific technical scheme as follows: the utility model provides a lithium bromide unit solution vacuum sampler, sample thief body including cylindrical seal structure, the circular surface in upper portion of sample thief body is provided with and stretches into two honeycomb ducts of body inside and sets for first honeycomb duct and second honeycomb duct, first honeycomb duct is the same with second honeycomb duct structure, all be provided with the valve on first honeycomb duct and the second honeycomb duct and be used for completely cutting off the body inside and external air contact, the cylindrical below of body is provided with one and stretches into the honeycomb duct of body inside and set for the third honeycomb duct, be provided with the valve on the third honeycomb duct and be used for completely cutting off the body inside and external air contact.
In the technical scheme, a vacuum pump is connected to a first flow guide pipe, valves on a second flow guide pipe and a third flow guide pipe are closed, a valve on the first flow guide pipe is opened, the vacuum pump works to pump out air in a sealed sampler body to enable the pressure in the sampler body to be about 4-5mmHg, the valves on the vacuum pump and the first flow guide pipe are closed, the second flow guide pipe is connected to a lithium bromide unit, the valve is opened, lithium bromide solution flows into the sampler body under the action of external pressure, the valve on the second flow guide pipe is closed after the required solution using amount is reached, the valve on the third flow guide pipe is opened, and the lithium bromide solution in the sampler body flows out from the third flow guide pipe under the action of gravity, so that technicians can analyze the flowing lithium bromide solution to determine the impurity concentration, thereby determining whether to better condition the lithium bromide solution in the unit.
The utility model discloses a further improvement, the valve that sets up on first honeycomb duct, second honeycomb duct and third honeycomb duct is vacuum valve.
The utility model discloses a further improvement, the body adopts transparent material to make, and the body that transparent material made is convenient for the technical staff from the outside observation inflow to this internal solution how much.
The utility model discloses a further improvement, the body adopts stainless steel material to make, is provided with transparent observation window on the body, and the observation window adopts transparent material to make and inlays on the outer wall of body, and the body life that stainless steel material made is more permanent, also is convenient for more clear up, inlays on the body outer wall that stainless steel material made observation window that transparent material made and is convenient for the technical staff from the outside observation inflow to the how much of this internal solution.
