The utility model discloses do further preferred, the top of case has the handle.
It is right to do further preferred the utility model discloses, the valve plate package rubbing board body, the terminal surface shape of face forms annular cavity under the plate body.
It is right to the utility model discloses do further preferred, form the annular chimb corresponding with the valve plate on the high vacuum passes a kind passageway inner wall annular chimb up end forms the annular convex body that matches with annular cavity.
It is further preferred to the utility model discloses, what the appearance passageway was passed in the high vacuum is close the handle side is the import, and the opposite side is the export.
To the utility model discloses do further preferred, the high vacuum passes a kind passageway and designs for through type.
To the utility model discloses do further preferred, the below department that the appearance passageway was passed in the high vacuum forms the evagination.
To the utility model discloses do further preferred, the both ends that the appearance passageway was passed in the high vacuum form the installation end respectively.
Compared with the prior art the utility model discloses the beneficial effect who reaches is:

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
As shown in fig. 1-4, the utility model relates to a high vacuum through type control valve, including valve body 1, its characterized in that: and a high-vacuum sample transmission channel 2 which is obliquely arranged is arranged at the lower part of the valve body 1.
The utility model is further optimized, the valve body 1 comprises a valve body cavity 3 which is internally communicated with the high vacuum sample transmission channel 2 and is integrally formed, a thread wall 6 is formed in the valve body cavity 3, a valve core 4 connected by threads is arranged in the valve body cavity 3, a valve plate 5 is arranged at the bottom of the valve core 4, the valve plate 5 and the inner wall of the high vacuum sample transmission channel 2 are sealed, a handle 7 is arranged at the top of the valve core 4, the valve plate 5 comprises a plate body 51, a ring-shaped cavity 52 is formed at the lower end surface of the plate body 51, a ring-shaped convex edge 2 corresponding to the valve plate 5 is formed on the inner wall of the high vacuum sample transmission channel 2, a ring-shaped convex body 22 matched with the ring-shaped cavity 52 is formed on the upper end surface of the ring-shaped convex edge 21, good sealing is formed, the high vacuum sample transmission channel 2 is close to the inlet at the side of, the high-vacuum sample transmission channel 2 is designed in a straight-through mode, an outer convex part 8 is formed below the high-vacuum sample transmission channel 2, and mounting ends 9 are formed at two ends of the high-vacuum sample transmission channel 2 respectively, so that the high-vacuum sample transmission channel is convenient to mount and connect.
When the handle is rotated, the valve core is driven to rotate up and down by the handle, the valve core drives the valve plate to move up and down, and when the valve plate rises, the high-vacuum sample conveying channel has space, so that samples in the high-vacuum sample conveying channel are circulated; when sampling is carried out, the handle is rotated to lead the rotating rod to rotate downwards and drive the valve plate to descend, so that one end of the valve plate is tightly attached to the high-vacuum sample transmission channel, and a sample can not flow in any more to finish sampling; and a closing valve is not required to be arranged, so that the cost is greatly reduced.
The utility model discloses in the high vacuum passes a kind passageway and is through type design, being close of a kind passageway is passed in the high vacuum handle side is the import, and the opposite side is the export. The high-vacuum sample transmission channel is designed in a straight-through mode, and the defect that sample transmission cannot be achieved when a traditional valve body works can be easily overcome.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
