Description
Technical field
The present invention relates to a kind of tank seal device, particularly relate to a kind of pure water box seal device.
Background technology
Extensively need pure water in the production of industries such as pharmacy, chemical industry, electronics and semiconductor.The equipment of making pure water generally all needs rearmounted pure water case in order to the deposit pure water, and this just need seal water tank, in case pure water contacts with external substance such as air etc. in the process that stores and causes pure water contaminated, deteriorating water quality.
At present, the encapsulating method of pure water case has multiple, and wherein usefulness more has two kinds of water-stop and nitrogen-sealeds.
Water-stop technology is general to be adopted water tank overflow pipe or the terminal water-immersed method of water tank escape pipe with secluding air." sweet-water tank sealing device " (patent No.: 02219076.7) promptly be a kind of like this technology.It will water tank escape pipe lower end immerses the sealing of carrying out water tank in the reservoir, sets up air cleaning unit simultaneously on the admission pipe of water tank, and when in the water tank during level fluctuation, air purifies the laggard water tank of going into, the pressure that balanced reservoir is inside and outside through air cleaning unit.Though this technology also has sealing effectiveness advantage preferably, weak point is that air cleaning unit is more loaded down with trivial details, needs supporting chemical chemicals dosing plant, the equipment complexity, and Operation and Maintenance inconvenience consumes a large amount of chemical agents simultaneously and causes the running cost height.
Nitrogen-sealed technology utilization nitrogen chemical property is the characteristics of inertia, the vacant part more than the liquid level in the water tank is full of with nitrogen, and deaeration, sealing effectiveness is better like this.But present nitrogen-sealed technology is poor for the external and internal pressure that level fluctuation in the balanced reservoir causes, adopt the form of installing safety valve on nitrogen pipeline more, adding or discharging of nitrogen carried out in action by automatic device control safety valve, thereby realizes the balance of water tank external and internal pressure.This technology has advantage simple to operation, but it is relatively poor that weak point is a security reliability, and when safety valve hinders can't move the time for some reason, adding or discharging of nitrogen is just obstructed, water tank external and internal pressure difference can't obtain balance timely, the danger that water tank still has distortion even breaks.
Summary of the invention
It is a kind of simple that purpose of the present invention will provide exactly, good sealing effect, safe and reliable pure water box seal device.
Technical scheme of the present invention is design like this: a kind of pure water box seal device, comprise the pure water case, be characterized in: establish sealing device in the outlet of pure water case bleed off pipe, the sealing device upper end is provided with filling pipe interface, pure water case bleed off pipe interface and pneumostome, the sealing device lower end is provided with drain interface, sealing device inside is divided into two Room up and down with dividing plate, is communicated with communicating pipe between two Room.The sealing device pneumostome communicates with atmosphere.
Apparatus of the present invention need to be used in combination with air seal technology (as nitrogen) in the pure water case.
Characteristics of the present invention are: sealing device is divided into two Room up and down, the nozzle position of indoor each pipe all passes through meticulous design, when guaranteeing the sealing of pure water case, can guarantee the normal overflow of pure water case again, when abnormal conditions take place, air also can enter pressure inside and outside the pure water case balance pure water case by the sealing device, guarantees the safety of pure water case.
The profile of sealing device can be circular or square.
The present invention has the following advantages:
1. simple in structure, easy to operate.
2. under the normal condition, the above vacant part of liquid level is full of by inertia sealing gas (as nitrogen) in the pure water case, and balance each other with external atmosphere pressure, when liquid level in the water tank declines to a great extent or sealing gas abnormal conditions such as can't normally mend in the pure water case when taking place, air promptly can enter pressure differential inside and outside the pure water case balanced reservoir automatically by water seal arrangement, thereby has ensured the being perfectly safe property of pure water case.
Description of drawings
Accompanying drawing 1 is an artwork of the present invention
Accompanying drawing 2 is structure charts of sealing device of the present invention
1 is sealing device among the figure, and 2 is pure water case bleed off pipe, and 3 is pneumostome, and 4 is filling pipe, and 5 is valve, and 6 is gutter, and 7 is the pure water case, and 8 is the bleed off pipe interface, and 9 is the filling pipe interface, and 10 is communicating pipe, and 11 is dividing plate
Dotted portion is a sealing device internal construction part among the figure.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Pure water case bleed off pipe 2 outlet of pure water case 7 is connected with sealing device 1 by the bleed off pipe interface 8 of sealing device 1, filling pipe 4 continuous low discharges to sealing device 1 moisturizing, this moisturizing is preferably pure water, fresh pure with maintenance sealing device 1 interior water.Indoor on sealing device 1, moisturizing water level and suitable for reading flushing of communicating pipes 10, pneumostome 3 lower port are lower than communicating pipes 10 upper port certain altitude, and are submerged in below the moisturizing water level.Moisturizing is by entering the following chamber of sealing device 1 communicating pipe 10, and following indoor water level flushes with gutter 6 upper port, communicating pipes 10 lower port be lower than gutter 6 upper port certain altitudes, and be submerged in below the water level.
Under the normal condition, the inertia sealing gas in the pure water case enters chamber on the sealing device by bleed off pipe, and vacant part is full of more than will going up the chamber water level; Outside air enters sealing chamber down by gutter, and will descend water level above vacant part in chamber to be full of.Suppose that pneumostome lower port and last chamber water level (being the communicating pipe upper port) distance is H
1, communicating pipe lower port be H with following chamber water level (being the gutter upper port) distance
2, the pressure of sealing gas is P in the pure water case
1, external air pressure is P
2, and establish Δ P=P
1-P
2Have following relation to set up:
I) work as P
1＞P
2+ H
2The time, i.e. Δ P＞H
2The time, the blanket gas in the pure water case was known from experience by the communicating pipe in pure water case bleed off pipe and the sealing device, entered atmosphere by stack at last, thereby had avoided the pure water case to cause damaging because of internal high pressure.
Ii) work as P
1+ H
1＜P
2The time, promptly Δ P＜-H
1The time, outside air can enter the pure water case by sealing device pneumostome and pure water case bleed off pipe, thereby has avoided the pure water case to cause damaging because of internal negative pressure.
By i) and analysis ii) find out, the hypertonia of pure water case inner sealing gas or low excessively no matter, this sealing device can both be guaranteed the being perfectly safe property of pure water case.
And from i) and ii) reach a conclusion, generally speaking, as long as control-H
1＜Δ P＜H
2, the pressure differential that also is about to interior sealing gas of pure water case and outside air is controlled at-H
1And H
2Between, the pure water case can obtain safe and reliable sealing.
This beneficial effect of the invention is, device structure is simple, and operating cost is low, good sealing effect, and pure water tank is safe.
