Description of the Invention: [Technical Field of the Invention] The present invention relates to a valve, and more particularly to a bottom valve that does not contaminate a fluid when discharging a fluid. [Prior Art] '(4)-General slurry_mixing process equipment, most of them will be installed in the bottom of the mixing tank or the conveying slurry line to control whether the slurry in the (4) barrel or pipeline enters the next process. "Refer to Fig. 1 2 4] A control valve 6 installed in the bottom of a mixing drum 5 for accommodating a slurry. The mixing drum 5 has a barrel wall 51 and a perforation 52 of the barrel wall 51. The valve 6 includes a valve body 61 including an inlet 6U with the perforations m, *, an extension tube 62 extending from the valve body 61 and the valve, and a control unit 〇, the control unit α ^ a valve 631 that is movable relative to the _61, a rod (4) that is connected to the extension tube 62 and connected to the reading door 631, and a 〇-shaped ring 633 that is embedded in the valve stem 632, and An adjustment member (1), the adjustment member 634 has a sleeve 63/, and a grip 636 extending from the sleeve 635. When the dip in the mixing drum 5 is to be discharged, the grip bar only needs to be pulled. The sleeve 635 is screwed up. At this time, the sleeve milk will push the reading on the crucible to move. The valve 631 opens the inlet of the valve body 61 to allow the slurry to flow out of the mixing tank 5. Conversely, when the slurry is to be stopped, it is only necessary to reversely pull the grip 636 to push the sleeve 635 downward to push the valve stem 632 downward until the valve 631 closes the inlet 201020433 611. . Although the above control valve can achieve the purpose of controlling whether the slurry flows out of the search bucket $, it still has the following disadvantages: 1. High cost: since the valve body 61 of the control valve 6 and the extension tube 62 are formed by precision molding Moreover, the internal polishing is not easy, so that the cost of the control room 6 is high. 1. Contaminant slurry: the 0-ring 633 will drive the slurry and the valve stem 632 to rub against the extension tube 62 during the movement of the valve stem 632. Therefore, if the slurry particles are small and Hard (for example, the ceramic wide charge, the size of the 陶 陶 颗粒 颗粒 颗粒 〇 〇 〇 〇 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The slurry is contaminated by being mixed into the slurry discharged from the scramble tank 5.
