Description
Technical field
The utility model relates to a kind of vacuum controller, relates in particular to a kind of vacuum controller that is applicable to rotary evaporator.
Background technology
Rotary evaporator is a kind of evaporation instrument of laboratory widespread use, and its principle is: under vacuum condition, heated at constant temperature makes the rotation of revolving bottle constant speed, and material forms large area film, high-efficiency evaporating at the bottle wall.The existing patent No. is characterized in that for the Chinese utility model patent that the CN201120456250.8 name is called " rotary evaporator " discloses a kind of structure comprise mainframe, described mainframe is provided with sleeve; One side of described sleeve connects evaporative flask, and opposite side connects condensing unit, and described condensing unit is provided with outlet straight down, and the outlet of described condensing unit connects receiving flask; The below of described evaporative flask is provided with heating arrangement.This utility model is simple in structure, and is cheap for manufacturing cost, and can be applied to the concentration operation of microcomponent.But because rotary evaporator itself is not joined vacuum controller, the vacuum pump performance is higher than expection really, vacuum tightness rises rapidly during each concentrating sample, be prone to boiling explosion phenomenon, sample concentration is produced harmful effect, but also the air escape cock venting that need open Rotary Evaporators vacuumizes after waiting to exit again, delayed the time; Perhaps, mix vacuum controller at Rotary Evaporators and control vacuum tightness, make that the concentration process of sample is smooth, but the vacuum controller on the market is expensive.Therefore, need do further to improve to the structure of this rotary evaporator.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of can control vacuum tightness, anti-bumping and the low vacuum controller that is used for rotary evaporator of production cost at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the vacuum controller for rotary evaporator of the present invention, include vacuum meter and throttling valve, it is characterized in that: described vacuum controller also includes surge flask, be stamped bottle cap on the bottleneck of described surge flask hermetically, described throttling valve is arranged at an end of snorkel, and the intracavity inter-connection of the other end of described snorkel and surge flask, the structure of described vacuum meter energy display buffer bottle inner chamber vacuum tightness is installed on the surge flask, the inner chamber of described surge flask is connected with vacuum pump by exhaust tube, and the inner chamber of described surge flask is connected with evaporator boat in the rotary evaporator by wireway.
As improvement, described bottle cap is the rubber cork, and described rubber cork is fixed with each other by the internal thread of the bottleneck of external thread and surge flask, satisfies the effect that vacuum tightness is cushioned herein.
Improve, described bottle cap is the rubber cork again, and described rubber cork is the little truncated cone-shaped of the big bottom of top bore bore, and described rubber cork is to be inserted on the bottleneck of surge flask, good airproof performance, purity and the stability of guarantee vacuum tightness.
Improve again, on described bottle cap and run through bottle cap four glass tubes are fixedly arranged, four glass tube openings that are positioned at described bottle cap top are connected with snorkel, exhaust tube, wireway, vacuum meter respectively, four glass tube openings that are arranged in described surge flask inner chamber respectively with the surge flask intracavity inter-connection, to realize the running of normal overall vacuum buffering.
Compared with prior art, advantage of the present utility model is: the described simple vacuum controller of rotary evaporator that is applicable to has low cost, high-efficiency characteristics; The setting of surge flask and throttling valve, airshed can fine be regulated continuously, the degree of regulation height; The demonstration effect of vacuum meter has improved the vapo(u)rization system vacustat in addition, and vacuum buffer control is effective, the anti-bumping performance that tool is good.

Fig. 2 is the exploded view of Fig. 1.
Embodiment
Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment.
Extremely shown in Figure 2 as Fig. 1, the vacuum controller that is used for rotary evaporator of present embodiment, include vacuum meter 6 and throttling valve 7, it is characterized in that: described vacuum controller also includes surge flask 1, be stamped bottle cap 2 hermetically on the bottleneck 11 of described surge flask 1, described throttling valve 7 is arranged at an end of snorkel 5, and the intracavity inter-connection of the other end of described snorkel 5 and surge flask 1, the structure of described vacuum meter 6 energy display buffer bottles 1 inner chamber vacuum tightness is installed on the surge flask 1, the inner chamber of described surge flask 1 is connected with vacuum pump by exhaust tube, and the inner chamber of described surge flask 1 is connected with evaporator boat in the rotary evaporator by wireway.
Described bottle cap 2 is preferably the rubber cork, described rubber cork is fixed with each other with the internal thread 31 of the bottleneck 11 of surge flask 1 by external thread 21, perhaps, the rubber cork is the little truncated cone-shaped of the big bottom of top bore bore, and is inserted on the bottleneck 11 of surge flask 1.On described bottle cap 2 and run through bottle cap 2 four glass tubes 4 are fixedly arranged, four glass tube 4 openings that are positioned at described bottle cap 2 tops are connected with snorkel 5, exhaust tube, wireway, vacuum meter 6 respectively, four glass tube 4 openings that are arranged in described surge flask inner chamber respectively with surge flask 1 intracavity inter-connection.
Described throttling valve 7 is preferably the copper needle-valve, and degree of regulation is than higher.Needle-valve is a kind of micrometering valve, and its valve plug is aciculiform, and is main as regulating airshed.Micrometering valve requires valve port to open change gradually greatly, can fine regulate continuously from being closed to the unlatching maximum.Needle plug can be realized this function.Needle plug is generally with the steel minute hand through quenching, and valve seat is to make with soft materials such as tin, copper.Its conical surface of sealing dependence of needle and valve base chamber closely cooperates and reaches.The tapering of needle has 1: 50 and two kinds of 1: 60 cone angles, and poppet surface will pass through fine gtinding.The sealing of valve rod and valve base chamber realizes by corrugated tube.
Use principle of the present utility model is: during use, elder generation reaches maximum to throttling valve, slowly turns down then to make system reach appropriate vacuum degree.Can for the sample that different solutions concentrates, select different vacuum tightness according to the personal experience, guarantee that sample concentration is smooth.Do not need the special messenger on the limit yet and prevent that boiling explosion phenomenon from taking place.Therefore, the utility model low cost, effective are worthy of popularization.
