Description
Technical field
The utility model relates to a kind of storage device of experimental water, is specifically related to storage and the application apparatus of water in the lab analysis detection.
Background technology
Experimental water is a very important index that affects experimental result.Specification and the grade of experimental water all stipulated in the standard method of most of analyzing and testing, to guarantee the accuracy of experimental result.The water that in the present analysis laboratory prepared by multiplex water purification machine is as experimental water, the indexs such as the various indexs of the water that water purifior has just prepared such as electrical conductivity, microorganism, ion concentration all meet the requirements, but water is placed more than 3 hours, generally do not reach requirement, can affect experiment precision and real result.The pure water prepared in addition, once in exhaustless situation, outwelling, has been wasted valuable water resource.At present laboratory is generally adopted and is faced with existing pure water processed or once prepare on a small quantity pure water, meets requirement of experiment, but some experimental water amounts greatly, water can waste plenty of time and manpower in laboratory frequently for this reason.
Summary of the invention
The purpose of this utility model is to provide a kind of device that can the long preservation experimental water.Water storage device and water-making machine, outlet pipe seamless link are to avoid outside contamination, stable with electrical conductivity, microorganism and the ionic strength that guarantees water quality at the confined space inflated with nitrogen simultaneously, thereby guarantee that the experimental water parameters is qualified.
The utility model comprises water purifior tube connector, pure water by-pass valve control, water purifior, water tank main body, nitrogen cylinder, nitrogen flow control valve, steam vent, drain tap, feed pipe, feed pipe valve.
The water tank main body is cylindrical, and its diameter is 20-100 cm, is highly 40-150 cm.
The nitrogen pipeline of nitrogen cylinder and water tank main body is provided with detachable activated carbon chimney filter, to remove by filter the impurity in nitrogen, between detachable activated carbon chimney filter and nitrogen cylinder, be provided with the nitrogen flow control valve, can control flow velocity and the pressure of nitrogen, the nitrogen tube end gos deep into the bottom of water tank main body, apart from bottom half 5-10cm.
Steam vent is opened the end face in the water tank main body, establishes drain tap on its outlet pipe, and drain tap is one way valve.
Water purifior is connected with the water tank main body by the water purifior tube connector, on the water purifior tube connector, is provided with the pure water by-pass valve control.
Feed pipe is positioned at 5-10cm place, water tank main body lower end, is provided with the feed pipe valve between feed pipe and water tank main body.
Described nitrogen flow control valve pressure range is 0-1.5MPa, and the flow range is 0-100mL/min.
The beneficial effects of the utility model are:
1, water space is full of nitrogen with starvation, avoids the index generation marked changes such as electrical conductivity of experimental water.
2, pure water source, storage and supply are in air-tight state on the whole, to guarantee not to be subjected to the pollution of external microbe, laboratory chemical pollutant, escaping gas etc.
3, steam vent can effectively be regulated the pressure of experimental water in casing, to supply to external world the experimental water of convenient pressure.
4, the device overall structure is simple, and easily operation, can carry out dimensional variations according to the laboratory actual conditions, has stronger practicality.
The accompanying drawing explanation
Fig. 1 is the utility model structure chart.
The specific embodiment
Below in conjunction with embodiment, the utility model is further described.
As shown in Figure 1, the storage device of experimental water comprises following part: water purifior tube connector, pure water by-pass valve control 2, water tank main body 9, nitrogen cylinder 7, nitrogen valve 6, stack 3, drain tap 4, feed pipe 10, feed pipe valve 8.
The water tank main body is cylindrical, and its diameter is 20-100 cm, is highly 40-150 cm; Its surfaces externally and internally material all adopts stainless steel.
The tube connector of nitrogen cylinder and water tank has detachable activated carbon chimney filter 5, to remove by filter the impurity in nitrogen.Nitrogen valve 6 can be controlled flow velocity and the pressure of nitrogen, and the pressure range is 0-1.5MPa, and the flow range is 0-100mL/min.The nitrogen tube end gos deep into the bottom of storage tank, apart from bottom half 5-10cm.
The inner surface material of stack is stainless steel, and diameter is 1-5 cm, and valve is one way valve, can prevent that the external contamination thing from entering when regulating the pressure of water tank.
Feed pipe is positioned at 5-10cm place, casing lower end, and the feed pipe front end is the contract type, and the outer end diameter is 1-3cm, and inner diameter is 4-5cm.Adopt the design of above-mentioned contract type to be connected to facilitate with the pipeline of different size.
The specific works flow process is:
At first close the feed pipe valve, open the nitrogen valve, be full of nitrogen at casing, then open valve, open simultaneously valve, allow the made pure water of water purifior 1 flow into casing.When pure water reaches casing 3/4-4/5, close pure water by-pass valve control and drain tap.The nitrogen valve pressure is 0.2MPa.Feed pipe is connected to the instrument that needs water, or the direct experimental water of suitable volumes that connects at the feed pipe place is for experiment.After water intaking completes, close the nitrogen valve.In the water intaking process, higher when the water intaking position, when pressure of supply water can not meet water demand, improve the pressure of pure water by-pass valve control, to meet the hydraulic pressure needs; Excessive when pressure of supply water, when the flow rate of water flow of the water supply mouth of pipe is too high, can open the drain tap appropriate time, to reduce the storage tank internal pressure, thereby reduce the pressure that feed pipe exports current.
After using 3 months, the detachable activated carbon on nitrogen cylinder and tube connector will be changed in time, to guarantee good nitrogen purge effect.
