Description
Technical field
The present invention relates to a kind of pharmaceutical fields, more particularly to a kind of high pressure resistant sterile formula valve.
Background technique
Existing food service industry, for pharmaceutical industry in production, due to being used for human oral or injection, interiors of products is not
There can be bacterium, otherwise can cause harm to the human body, therefore its aseptic must be kept in the production process of product.So
When carrying out the Design of Production Line of product, the equipment and pipe fitting valve using sanitation-grade are needed, to reduce microbiological contamination in production process
Risk.And many products need very high pressure (such as 200bar or more) in the actual production process, so such product
Used valve needs to be resistant at least 200bar pressure above on production line, and internal structure belongs to hygienic level structure, cannot
There is remaining sample to lead to not clean or sterilize completely.
Existing valve, such as ball valve in the market, needle-valve etc. or can bear high pressure (200bar) or more, but can not meet
The requirement of hygienic level structure, and existing sanitation-grade diaphragm valve can not be resistant to the operating pressure of 200bar or more:
1) non-hygiene level structure: the valve that some is resistant to 200bar pressure or more currently on the market only has needle-valve and ball
Valve, plunger valve, but these types of valve is not admitted to hygienic level structure, inside is there are dead angle, can not be thoroughly clear when on-line operation
The case where washing and sterilize completely, often will appear internal microbiological contamination contaminated samples appearance.
2) proof pressure is low: the pressure that the diaphragm valve of existing hygienic level structure is usually resistant in the market only has 5~
6bar, and when product needing high pressure during the preparation process more than (such as 200bar), such valve is undesirable,
It is not available.
In view of the above shortcomings, the designer, is actively subject to research and innovation, to found a kind of need in condition of high voltage
Lower work, and need to meet the high pressure resistant sterile formula valve of the requirement of the valve of hygienic grade standard, make it with more industry
On utility value.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide one kind can empty internal remaining sample, and energy certainly
It is high pressure resistant, to meet the high pressure resistant sterile formula valve of the high pressure resistant sterile formula valve of sanitation-grade design requirement.
High pressure resistant sterile formula valve of the invention, including valve body, the body top are equipped with feed inlet, the body base
Equipped with discharge port, the L-type feeding-passage being connected with the feed inlet is equipped in the valve body and is connected with the discharge port
Logical linear type tapping channel, the L-type feeding-passage vertical section are connected with the feed inlet, the L-type feeding-passage
The joint of horizontal segment and the linear type tapping channel forms sealing surface, and valve seat is equipped in the valve body, is set in the valve seat
There is the cut-off channel being located along the same line with the horizontal segment of the L-type feeding-passage, is fixed with interior spiral shell in the cut-off channel
Line set and valve rod compatible with the inner screw sheath, penetrate through between the cut-off channel and L-type feeding-passage and pass through institute
State valve rod and sealing face contact sealing.
It further, further include O-ring seal, the inner wall of the valve seat offers compatible with the O-ring seal
Groove.
Further, the corner of the L-type feeding-passage is fillet.
Further, the valve body is cylinder shape valve.
It further, further include the handle for being fixed on the valve rod end.
Further, the L-type feeding-passage or linear type tapping channel or end channel thickness be greater than or
Equal to 25mm.
Further, the valve body, valve seat and valve rod are respectively 316L stainless steel body, 316L stainless steel valve seat and 316L
Stainless steel valve rod.
According to the above aspect of the present invention, the present invention has at least the following advantages:
1, internal without dead angle, sanitation-grade design requirement can be met from emptying；
2, it is resistant to 200bar pressure above.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And can be implemented in accordance with the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention and the accompanying drawings.
