Abstract
The utility model discloses a biological feed bag pressure control valve, which consists of an air guide cavity, a cap and the like. The lower end of the air guide cavity is provided with a flange, the upper portion of the air guide cavity is provided with a concave flange, the upper end of the air guide cavity is slightly higher than the top of the concave flange, a plurality of exhaust holes are arranged at the bottom of the concave flange, the cap matching with the shape of the concave flange is connected to the concave flange, a membrane is clamped between the concave flange and the cap, and the cap is provided with vent holes. The flange of the biological feed bag pressure control valve is adhered with a biological feed bag hermetically, and a bottom opening of the air guide cavity is communicated with internal space of the biological feed bag. The biological feed bag pressure control valve is simple in process, and can control internal and external pressure of the feed bag automatically, and particularly when the internal gas pressure of the feed bag is higher than the external gas pressure of the feed bag, gas in the feed bag can impact the membrane via the air guide cavity so as to be exhausted from the exhaust holes. The vent holes can effectively reduce gas pressure of an inner cavity of the cap. When the internal gas pressure and the external gas pressure of the feed bag are equal, the membrane returns to cover the head of an air guide post hermetically, thereby realizing sealing the feed bag.
Description
Technical field
The utility model relates to gas pressure regulation device in a kind of biological feedstuff bag, particularly relates to a kind of biological feedstuff bag voltage-controlled valve.
Background technology
Biological feedstuff promptly is the feed that interpolation adopts the additive of biotechnology making to be made.As add the feed that biology feed additive that biotechnologys such as utilization genetic engineering, cell engineering, enzyme engineering, microbial fermentation engineering, protein engineering make is made.Will adopt fermentation tank to carry out feed fermentation in the feed process, finished product was made in pack after fermentation was finished.The defective that existing biological feedstuff processing and finished product exist is: the one, and complex process in the machining process, with after leavening fully mixes, the employing fermentation tank carries out anaerobic fermentation with feedstuff.Caused processing cost to increase like this.The 2nd, after the biological feedstuff pack packed, biological feedstuff did not thoroughly easily produce a large amount of gases as sterilization and bursts the feed package bag.Prior art is bursting at the collision in order to prevent the feed package bag, often punches on the feed package bag to reduce gas pressure in the bag.Because lost the sealing of packaging bag, it is rotten that feed is hardened.
Summary of the invention
The utility model is at the deficiencies in the prior art, and the biological feedstuff bag voltage-controlled valve that a kind of biological feedstuff processing cost is low, can protect the biological feedstuff bag not burst by gas is provided.
The utility model is realized by following technical scheme, biological feedstuff bag voltage-controlled valve, form by air guide chamber, buckle closure etc., it is characterized in that lower end, described air guide chamber is provided with the outer, top, air guide chamber also is provided with the spill outer, air guide chamber upper end is a little more than top, spill outer, and bottom, spill outer is provided with several steam vents, is connected with the buckle closure that matches with described spill outer profile on the spill outer, gland has film between spill outer and buckle closure, and buckle closure is provided with air-vent.
The beneficial effects of the utility model are, the outer of biological feedstuff bag voltage-controlled valve and the sealing of biological feedstuff bag are bonding, and mouth is connected with the interior space of biological feedstuff bag at the bottom of the air guide chamber.Processing is simple, can control the inside and outside gas pressure of feedbag automatically, when gas pressure in the feedbag greater than bag during outer air pressure, gas can be discharged along steam vent by the air guide chamber film of getting excited in the bag.Air-vent can effectively reduce buckle closure inner chamber gas pressure.When gas pressure inside and outside the feedbag equated, film resetted seal cover on the air guide column cap, realized the sealing to feedbag.So can ferment in the feedbag of directly packing into feedstuff with after leavening fully mixes.Save fermentation tank and carried out the anaerobic ferment process step, reduced processing cost.Prevented the drawback that the feed package bag is bursting at the collision simultaneously.It is once big improvement to prior art.

Among the figure, 1. air-vent, 2. buckle closure, 3. film, 4. spill outer, 5. steam vent, 6. outer, 7. air guide chamber.
The specific embodiment
Biological feedstuff bag voltage-controlled valve, form by air guide chamber (7), buckle closure (2) etc., lower end, described air guide chamber (7) is provided with outer (6), top, air guide chamber (7) is provided with spill outer (4), air guide chamber (7) upper end is a little more than top, spill outer (4), bottom, spill outer (4) is provided with several steam vents (5), be connected with the buckle closure (2) that matches with described spill outer (4) profile on the spill outer (4), gland has film (3) between spill outer (4) and buckle closure (2), and buckle closure (2) is provided with air-vent (1).The outer (6) of biological feedstuff bag voltage-controlled valve is bonding with the sealing of biological feedstuff bag, and air guide chamber (7) end mouth is connected with space in the biological feedstuff bag.Can control the inside and outside gas pressure of feedbag automatically, when gas pressure in the feedbag greater than bag during outer air pressure, gas can be discharged along steam vent (5) by air guide chamber (7) films (3) of getting excited in the bag.Air-vent (1) can effectively reduce buckle closure (2) inner chamber gas pressure.When gas pressure inside and outside the feedbag equated, film (3) resetted seal cover on termination, air guide chamber (7), realized the sealing to feedbag.So can ferment in the feedbag of directly packing into feedstuff with after leavening fully mixes.
