Description
Technical field
The utility model belongs to bioreactor fermenting tub field, relates in particular to a kind of sterilizing sampling integral valve.
Background technique
Various fermenting tubs (mechanical agitation type, gas-lifting type, strong-magnetic) during the fermentation, need the online yeastiness in tank that detects, and sampling detects its microorganism of evaluation and cultivates situation, to determine that various control parameters in tank are carried out to (PH, DO etc.) to be adjusted.Thereby the accuracy of sampling is particularly important, the common compounding practice that pass through a plurality of valves of way in the industry, to the sterilizing that carries out disinfection of sampling path, then samples.Though do like this, can get qualified sample liquid, have following drawback:
1, easily malfunction operation, is limited by operator's professional skill;
2, sterilization time, quality can not sequencing, standardization, being subject to operator's factors vary affects sample liquid quality.
3, sample after also using autosterilization in some full-automatic bioreactor Zymolysis Equipment, but pipe valve is many, cost is more expensive, not susceptible to user acceptance.
The utility model provides (3-position-3-way) sterilizing sampling integral valve for a kind of fermenting tub, for fermenting tub in sampling link: " after the chamber that must thoroughly flow through to sample liquid, runner, sample tap sterilization ability sampling, to guarantee sample liquid purity " this requirement and determining.
According to this valve working principle, can be manually operated type, pneumatic type.
Model utility content
The technical problem that the utility model solves is to have overcome multi-valve linkage operation sterilizing to sample easy malfunction operation; Sterilization, sterilization time, quality can not sequencing, standardization; And pipe valve is many, the defect that cost is high.
This bright fermenting tub sterilizing sampling process that makes realizes control or telecontrol automatically, makes the updating and upgrading of a product.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is:
A sterilizing sampling integral valve, before it is characterized in that fermenting tub to sample, sterilizing and sampling process are intensive to a valve, have simplified the setting of pipe valve.Owing to becoming keying spool, be to-and-fro motion again simultaneously, conveniently realize motor-driven control.After being used in conjunction with electric elements, scalable is automatically to control.
Described integral valve, is comprised of a valve body and two spools, and described valve body is the valve pocket consisting of multiple tracks path, (this valve pocket is provided with threeway: a logical tank body discharge port, two-way vapor interface, threeway sample tap).Described a plurality of spool, is by A, and two common coordinated movements of various economic factors of spool of B complete sampling process.Described A spool is a sliding valve style main valve plug, and B spool is sample tap spool.A spool moves and is provided with three positions: i.e. left position, meta, right position.When meta by valve port on spool control valve body each do not communicate (obstructed with tank body material mouth, with steam source obstructed, with sample tap obstructed).When A spool moves to left position, the air inlet annular groove conducting steam source arranging on A spool and valve pocket path (now valve pocket and tank body discharge port are obstructed), open B valve (sampling cock) and can sample front sterilizing, sterilization, blowdown; When sterilizing reaches regulation requirement, A spool is multiple to meta, can prepare sampling.Continuation is therefrom moved to right position by A spool, and the annular groove conducting tank body discharge port arranging on A spool and valve pocket path (cutting off steam source and valve pocket path) are sampling simultaneously, (before sampling, first putting except part sample liquid is to guarantee sample liquid purity).After sampling finishes, again A spool is moved to leftmost bit (crossing neutrality line) valve pocket, sample tap after sampling is clean by steam flush, clean complete still again to meta, whole sampling process finishes.
This utility model patent has used the principle of valve body in liquid (or pneumatic) transmission cleverly, flow through route and the requirement of combining with fermentation tank sterilization, charging, sampling, blowdown uniqueness again, design this (3-position-3-way) sterilizing sampling cock, novel uniqueness, simple in structure feasible, easily manufactured, be easy to realize industrialization and produce.Product can divide each demand grade, meets various distinct device demands.
1, the entire infrastructure part of sterilizing valve all adopts S30408 material, and Sealing adopts the manufacture of high-temperature-resisting silicon rubber material, all reaches food stage sanitary standard.
2, valve body adopts stainless steel forgings, and structure is compacted.Spool in valve body is through hole, machining accuracy easy to control; Spool is the cylindrical part with a plurality of notches, without difficulty of processing.
3, the unlatching of sample tap or close employing polytetrafluoroethylmaterial material, reliable in action is without leakage, not microbiological contamination.
4, according to the configuration requirement of fermenting tub, the patented product can be realized the management control mode of different class, manual or pneumatic.Manually in leftward position, cam linkages is set; Pneumatic type is installed control cylinder and electrical apparatus element.
Programmed sequence of operations
1, the A spool that moves to left, steam enters valve pocket, opens the blowdown of B valve;--------(sterilization process)
2, the sterilizing A spool that moves to right after finishing is multiple to meta, spool cuts off each path--------(sterilizing finishes)
3, the spool (crossing neutrality line to rightmost position) that moves to right, A spool annular groove conducting tank body discharge port and valve pocket, steam off enters valve pocket passage in advance simultaneously, from B valve (sampling cock) mouthful sampling.---------(sampling process)
4, after sampling finishes, the A spool that again moves to left, to leftmost bit, is used steam flush sample tap.-------(cleaning after sampling)
5, complete will answering to meta by A spool rinsed in sampling, closes B valve simultaneously, and whole sampling finishes.
6 if pneumatic control can be enrolled program by sterilization time, sampling time (quantity), secondary cleaning time; Action first, after enroll program, carry out full-automatic sampling and control.
The utility model beneficial effect is:
1, simplify controlling of traditional biological reflecting device fermenting tub sterilizing sampling process, become many valves into a valve, and practicable centralized control.When adopting pneumatic type and after electric adapted, can carry out program control, realize the upgrading of product.
2, sterilization process specification is thorough, and sampling is reliable, is conducive to instruct procedure parameter change setting in fermentation tank culture.
3, owing to having strengthened the Online Monitoring Control of fermentation process, can effectively improve the quality of products, energy-conservation of consumption reduction, improves Business Economic Benefit and saves valuable efficient resource to country.
