Abstract
The utility model discloses a novel special valve for fermentation. The novel special valve for fermentation comprises a valve body, a transmission mechanism and a motor, the transmission mechanism isarranged in the valve body, and the motor is arranged at the bottom part of the valve body, wherein a flange is arranged at the top part of the valve body. The special valve for fermentation which adopts the above structure has the following characteristics: as the flange is arranged at the top part of the valve body, when in assembling or disassembling, the special valve only needs to be connected to the bottom part of a fermentation tank by the flange; therefore, the assembling and disassembling are quite convenient; moreover, a sealing ring which is arranged at the bottom part of the transmission mechanism can further improve the sealing property of the special valve and avoid pollution of mixed bacteria.
Description
Technical field
The utility model relates to valve class part, refers in particular to a kind of novel fermentation special valve, belongs to the technical field of Zymolysis Equipment accessory.
Background technique
Existing fermentation blowing and sampling cock automaticity are not high, owing to the reason that has two valves, vulnerable to pollution, sampling amount also can not get accurate control during operation, sealing is poor---and rare excessively liquid easily causes seepage by the disc face between the connecting passage joint, need the time of high pressure steam sterilization longer, sterilization back vulnerable to pollution.In order to address the above problem, Chinese patent literature discloses a kind of sampling cock, the name of the document is called " a kind of novel fermentation sampling cock ", the patent No. is " ZL200520073106.0 ", this sampling cock comprises valve body, be arranged on the steam inlet of valve body side, sample tap, be arranged on the liquid inlet at valve body top, and be separately positioned on the control valve of liquid inlet and steam inlet, be arranged on the driving mechanism in the valve body, be arranged on the motor of valve body bottom, the place, liquid inlet is provided with an interface disk, the periphery of described interface disk is provided with a sealing ring washer, the sampling cock sealing and the Security of this structure are better, reduced the living contaminants factor, but sampling cock has been connected to the sample tap of fermenting tub or cumbersome when fermenting tub disassembles.
The model utility content
Technical problem to be solved in the utility model provides a kind of easy to loading and unloading, good airproof performance, can take a sample automatically and novel fermentation special valve simple in structure
In order to solve the problems of the technologies described above, a kind of novel fermentation special valve of the utility model comprises valve body, is arranged on the driving mechanism in the described valve body and is positioned at the motor of valve body bottom that wherein, the top of described valve body is provided with a flange.
Above-mentioned a kind of novel fermentation special valve, wherein, the bottom of described driving mechanism is provided with an O-ring seals.
Above-mentioned a kind of novel fermentation special valve, wherein, described motor is a stepper motor.
Adopt the novel fermentation special valve of said structure,, during installation or removal, only need the bottom that the utility model is connected to fermenting tub to be got final product, therefore install and remove more convenient by flange because the valve body top is provided with a flange; And be provided with the sealing that seal ring can further improve this valve in the bottom of driving mechanism, avoid the pollution of assorted bacterium; In addition, utilize transmission that stepper motor becomes the respective corners displacement with the input pulse signal conversion accurately, with the irrelevant characteristic of load, by the valve body transmission sampling cock is opened, zymotic fluid is flowed out, thereby reach the purpose of automatic sampling (or discharging), simple in structure, the reliable operation of the utility model satisfies the sampling requirement of fermenting tub fully.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In order to solve the problems of the technologies described above, a kind of novel fermentation special valve of the utility model, comprise valve body 1, be arranged on the driving mechanism 3 in the described valve body 1 and be positioned at the motor 4 of valve body 1 bottom, the top of described valve body 1 is provided with a flange 5, and motor 2 can be the accurate stepper motor of transmission.Valve body 1 both sides are provided with steam inlet 11 and sample tap 12 (or discharge port), are provided with two-layer O seal ring-upper and lower O-ring seals 21 in the flange 5, and upper and lower O-ring seals 21 is located at respectively between the joint and valve rod 32 and valve body 1 inner chamber of flange 5 and tank body; 21 double protections of two-layer upper and lower O-ring seals, thus living contaminants prevented, and whole valve body 1 is made by stainless steel SUS316L material.Driving mechanism 3 is in sampling cock valve body 1 center, steam inlet 11 is connected the bottom of valve body 1 one sides, sample tap (or discharge port) 12 is connected valve body 1 opposite side top, steam inlet 11 is provided with diaphragm-type electromagnetic valve 13 and sample tap 12 is controlled by a diaphragm type pneumatic modulating valve 14, both and sampling cock internal communication, driving mechanism 3 bottoms are provided with an O-ring seals 31, play the seal action between valve rod 32 and the valve body 1, and this O-ring seals is made by the high temperature resistant silicon glue material.When starting the stepper motor 4 of sampling cock bottom, by driving mechanism 3 valve body 32 is moved up, open sample tap 12 (or discharge port), zymotic fluid flows into valve body 1 inner chamber from flange 5, flows out from sample tap (or discharge port) 12 again, reaches the sampling purpose.
Sampling flowsheet:
1) before the sampling, controller is opened the diaphragm-type electromagnetic valve 13 of steam inlet 11, feeds steam, the diaphragm type pneumatic modulating valve 14 of sample tap is opened after 5 seconds, steam flows out from sample tap 12, closes two solenoid valves automatically after keeping 30min～40min, finishes sterilisation purpose;
2) controller starts stepper motor 4 automatically, and because of the effect of gear, driving mechanism 3 extends upwardly with the motor rotation, stops behind certain position;
3) zymotic fluid flows into valve body 1 inner chamber from flange 5, opens diaphragm type pneumatic modulating valve 14 this moment automatically, from sample tap (or discharge port) 12 samplings, the aperture of control valve, may command sampling amount;
4) after sampling was finished, controller was closed diaphragm type pneumatic modulating valve 14 automatically, starts the stepper motor counterrotating simultaneously, and driving mechanism 3 is downward, because of the effect of last O-ring seals 21 separates getting in touch of fermenting tub and valve pocket;
5) after stepper motor [1] puts in place and stops, automatically open diaphragm-type electromagnetic valve 13 and diaphragm type pneumatic modulating valve 14, steam from diaphragm-type electromagnetic valve 13 advance, diaphragm type pneumatic modulating valve 14 goes out, automatically close two valves after keeping 30min～40min, at this moment, the bacterium of thoroughly having gone out in the valve pocket prevents living contaminants, also is next ready for operation simultaneously.
In sum, the controller that the utility model utilizes one-chip computer and programming technique to form is controlled the rotation of sampling cock bottom stepper motor automatically, stepper motor starts the back and by driving mechanism the interface of sampling cock and fermenting tub is opened or closed, and realizes sampling automatically.The utility model can be realized the purpose of quantitative sampling and automatic discharging, with two functions of a valve dual-purpose, and good airproof performance, easy to loading and unloading, safe and reliable, simple to operate, reduced factors such as living contaminants.
The utility model is not limited by above-mentioned mode of execution, and the technological scheme that employing equivalence replacement obtains is all in protection domain of the present utility model.
