By supplying cooling water from (22), both valve bodies Φ)
When the cooling water is swirled into the inside of the drain cap (23) (23), the water is drained from both valve bodies (can).
Therefore, the valve body (B) (
B) Sea corresponding to K 1) It is possible to absorb heat from the (1) side and prevent the generation of heat and distortion in that part, thereby maintaining highly accurate valve function. In addition, the inlet (8
) When a large amount of fluid is pressurized, the gap between the valve body (B) and Φ) is filled from inside the fluid welfare valve storage case 9), and the fluid pressure causes both valve bodies (B) and ■) to move toward the seat side. The sealing effect can be improved by pressing the fluid into the outlet (9) (9)
It is possible to discharge more. Note that if cooling water or inert gas is supplied through the supply port (8), the valve body (
B) (8) can be cooled to maintain highly accurate valve function as described above.

に実施できる特長を有する。As described above, the present invention provides a gate pulp that is configured to open and close by vertically moving a valve body in a direction perpendicular to a valve body through which fluid flows, and in which the valve body is opened and closed from within a valve storage case that is connected to and connected to the upper part of the valve body. Both valve bodies are installed on the seat side so that they can be moved up and down while keeping a distance between them, and when both valve bodies are damaged on the seat side of the valve box, the space between the two valve bodies is removed from inside the valve storage case. Since the fluid was pressed in so that both valve bodies could be suppressed to the seat side, it was assumed that the two valve bodies could provide reliable and good Kll control, and when the valve was closed, the fluid was press-fitted between the two valve bodies. The pressure of the fluid brings both valve bodies into pressure contact with the seat side of the valve body to increase the sealing effect, and the gate pulp can be made with high precision.It has a simple structure and can be easily implemented. have
