NOVELTY - The utility model design valve technology field, a non-blocking reaction kettle unfolding type discharging valve; the valve body is provided with a curved inner pipeline; two ends of the valve body is provided with a flange, sealing plug is installed on the front end of the push rod; the rear end face of the sealing plug position with the push rod is provided with an inner step structure; the fixing ring is inserted and sleeved on the outer wall of the push rod; and the inner ring surface of the fixing ring is in interference fit with the outer wall of the push rod; the fixing ring is matched with the inner step structure to sealing plug; the front end of the push rod is a tip; the tip passes through the sealing plug and the front end is protruded from the front end face of the sealing plug; the diameter of the tip tail section is gradually reduced from back to front; the diameter of the middle section of the tip is gradually increased from back to front; the diameter of the front section of the tip is gradually reduced from back to front; and the tip tail section; the connection part of the middle section of the sharp head and the outer ring surface of the front section of the sharp head is in smooth transition. The discharging valve can solve the problem that the material of the discharging port of the graphene material reaction kettle is blocked.
