Abstract
Claims
1. A structure for high vacuum pumping of a valve stem by changing the direction of the valve stem, characterized by, The utility model relates to a variable direction valve, which comprises a guide hole (8) arranged on a device body (7), a valve body (1) and a variable direction valve rod (2). The variable direction guide rod (3) is arranged in the guide hole (8), the valve body (1) passes through the guide hole (8), and the lower end of the valve body (1) is centrally provided with an avoiding groove (9) avoiding the variable direction guide rod (3), and the variable direction guide rod (3) passes through the avoiding groove (9) of the valve body (1) and is arranged.
2. The structure for high vacuum pumping of the variable direction valve stem according to claim 1, characterized in that: The valve rod (2) is arranged in the valve body (1), and the lower end of the valve rod (2) is threadedly connected with a valve rod connecting rod (4).
3. The structure for high vacuum pumping of the variable-direction valve stem according to claim 2, characterized in that: An inclined guide structure is arranged between the valve rod connecting rod (4) and the variable direction guide rod (3), so that when the variable direction guide rod (3) moves forward and backward, the valve rod connecting rod (4) rises or falls correspondingly.
4. The structure for high vacuum pumping of the variable-direction valve stem according to claim 3, characterized in that: The inclined guide structure comprises a guide groove (10) arranged on the variable direction guide rod (3) and a guide block (11) arranged on the valve rod connecting rod (4), and the guide groove (10) and the guide block (11) are both inclined structures.
5. The structure for high vacuum pumping of the valve stem with change of direction according to claim 1, characterized in that: One side of the device body (7) is provided with an air outlet (6), the air outlet (6) is communicated with the valve body (1) and is located at a position corresponding to the valve rod (2).
6. The structure for high vacuum pumping of the variable direction valve stem according to claim 1, characterized in that: The other end of the variable direction guide rod (3) is connected with an oil cylinder connecting rod (5).
7. The structure for high vacuum pumping of the valve stem with change of direction according to claim 4, characterized in that: The guide groove (10) is arranged in an inclined manner along the axial direction of the variable direction guide rod (3), so that when the variable direction guide rod (3) moves forward and backward, the guide block (11) moves in an inclined direction, thereby driving the valve rod connecting rod (4) to move linearly up and down.
8. The structure for high vacuum pumping of the valve stem with change of direction according to claim 1, characterized in that: The valve body (1) and the variable direction guide rod (3) are gap-fitted through the avoiding groove (9), so as to avoid interference between the valve body (1) and the variable direction guide rod (3) when the valve body (1) moves.
