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.
Utility model content
In order to solve the above technical problems, the purpose of the utility model is to provide one kind can empty internal remaining sample certainly,

The joint of the horizontal segment in road and the linear type tapping channel forms sealing surface, is equipped with valve seat, the valve seat in the valve body
It is interior to be equipped with the cut-off channel being located along the same line with the horizontal segment of the L-type feeding-passage, it is fixed in the cut-off channel
Inner screw sheath and valve rod compatible with the inner screw sheath, penetrate through and lead between the cut-off channel and L-type feeding-passage
Cross the 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.
