Abstract
The utility model relates to a sterile device technical field. Aseptic corrugated diaphragm (case), including upper seal part, ripple subtotal lower seal part, the upper seal is partial, ripple subtotal lower seal part constitutes a whole, be equipped with a hole on the aseptic corrugated diaphragm, intercommunication upper seal part, ripple part have just set up connection structure until the lower seal part in the lower seal part. Wherein the surface of ripple part has designed and has arranged the curved surface certainly, opens at aseptic valve, when closing, and liquid can be followed under the action of gravity slide from row curved surface. Above -mentioned connection structure is pre -buried nut, and pre -buried nut is suppressed to be fixed in lower seal part inside, and its internal thread is linked together with above -mentioned hole. The utility model discloses can realize that liquid from arranging, reduces liquid and remains, and connection structure is more firm between the axle of aseptic valve and the aseptic valve diaphragm, but greatly increased corrugated diaphragm's life.
Description
Technical field
The utility model relates to sterile equipment technical field, particularly a kind of sterile valve diaphragm and sterile valve, and described sterile valve diaphragm and sterile valve can be applicable to the technical fields such as food, medicine, biology.
Background technique
Because the clean level of the industries such as modern pharmaceutical, biotechnology, food chemistry to production environment and equipment requires higher, sterile equipment becomes manufacturing mechanism conventional in these industries, especially sterile valve equipment.Sterile valve technology is the new technology just occurred recently, and sterile valve equipment becomes the optimum pipeline valve of above-mentioned industry.
Common sterile valve is membrane valve and stop valve.Membrane valve has the features such as structure is simple, cheap, easy to clean, but its working life is short, needs certain angle during installation, easily damages, and easily cause the invisible costs such as shutdown, these all limit the using scope of membrane valve simultaneously.Be applied to the stop valve normally Bellows valves in sterile valve field, be arranged to bellows structure between the lower seal part of Bellows valves and valve body, ensure that the gnotobasis of valve.Bellows valves has features such as using reliable, life-span length, noresidue, volume little, easy for installation.Bellows valves technology maturation, more safe and reliable.Do not need specially bellows sterile valve to be set to leaning structure in Pipe installing, effectively can avoid blind spot, this point is better than membrane valve.The bellows diaphragm design of Bellows valves can increase the working life of diaphragm greatly.But, because Bellows valve corrugated regions when opening can exist the risk of liquid residue, and be directly threaded connection between the lower seal part of conventional bellows diaphragm and valve rod, the risk easily producing lower seal partial exfoliation in closing course is repeatedly opened at valve.
Therefore, how avoiding the liquid residue of bellows diaphragm, avoid lower seal partial exfoliation, add working life, is one of aseptic Bellows valves urgent problem.The utility model has established a kind of novel aseptic bellows diaphragm and sterile valve, and described sterile valve can solve the problems of the technologies described above.
In prior art, valve rod 8 and the lower seal part 4 of sterile valve are directly threaded connection, and arrange screw thread respectively at the internal surface of the outer surface of valve rod 8 and the closed sky on lower seal part 4 top.Because aseptic convolution diaphragm uses rubber-plastics material to make usually, the intensity of worm structure is more weak, when high frequency opens and closes valve repeatedly, fragmentation, fracture equivalent damage may be there is in worm structure, lower seal part 4 is come off from valve rod 8, so just have impact on the normal operation of equipment.And the pre-buried embedded nut 5 of the blind hole internal fixtion that is connected with the hollow of corrugated portion 3 in the inside of lower seal part 4 in the utility model, embedded nut can adopt the stronger material of intensity to make, lower seal part 4 and valve rod 8 being threaded togather by embedded nut 5, join strength is stronger, high frequency repeatedly open or throttle down state under, not easily there is the phenomenon that lower seal part 4 comes off from lower seal part 8.
The utility model has following beneficial effect: 1, aseptic convolution diaphragm is provided with from arranging curved surface, can realize liquid from row, avoids liquid to produce corrosion and contaminate subsequent liquid to diaphragm; 2, have employed embedded nut to relate to, is that the connection between valve rod and aseptic convolution diaphragm is more firm, and the situation of lower seal partial exfoliation not easily occurs; 3, described aseptic convolution diaphragm and sterile valve structure simple, install simple and easy, can be used in pipelines structure.
Summary of the invention
In view of there is above-mentioned technical problem in prior art, the utility model provides the bellows position of a kind of new aseptic bellows diaphragm and sterile valve to devise from arranging curved surface, to avoid occurring liquid residue phenomenon, simultaneously sealing portion Divisional is pre-buried nut, make valve rod divide with sealing portion between be threaded more firm, reliable.The concrete technological scheme that the utility model adopts is as described below.
The utility model provides a kind of aseptic convolution diaphragm 1, described aseptic convolution diaphragm 1 comprises top sealed portion 2, corrugated portion 3 and lower seal part 4, top sealed portion 2, corrugated portion 3 and lower seal part 4 form an entirety, described aseptic convolution diaphragm 1 is provided with a hole, connection top sealed portion 2, corrugated portion 3 until lower seal part 4, and are provided with linkage structure in lower seal part 4.Wherein, the outer surface of corrugated portion 3 devises from arranging curved surface, and when sterile valve unlatching, closedown, liquid can slide along described from row's curved surface under gravity, to realize liquid from arranging.
In further technological scheme, above-mentioned aseptic convolution diaphragm 1 also comprises embedded nut 5, and embedded nut 5 is pressed and is fixed on lower seal part 4 inside, and its screw thread is connected with above described holes.Described embedded nut 5 is in aseptic convolution diaphragm 1 preparation process, is embedded in aseptic convolution diaphragm 1.
The utility model additionally provides a kind of sterile valve 6, and described sterile valve is Bellows valves, and its bellows diaphragm is above-mentioned aseptic bellows diaphragm 1.
In aseptic convolution diaphragm 1 described in the utility model and sterile valve 6, liquid is devised from arranging curved surface in corrugated portion 3, namely sterile valve open or close state under, level or recessed position is not had at the upper surface of ripple, the position of level or projection is not had, as shown in Figure 1 at the lower surface of ripple yet.Like this, when valve opening, after liquid passes through, stop flow of fluid owing to there is not resistance at corrugated portion 3 place, under the effect of liquid self gravitation, liquid slowly can slide described aseptic convolution diaphragm along the outer surface of ripple.And when the valve is closed, corrugated portion 3 is subject to stretching action, resiliently deformable occurs, and be more conducive to the flowing of liquid after bellows-shaped is stretched, after liquid passes through, the easier outer surface along ripple slides described aseptic convolution diaphragm.
