Description
Technical field
The utility model relates to discharging valve technical field, especially a kind of manual upward-expansion type discharge valve.
Background technique
Discharging valve is mainly used in bottom discharging, blowing, the sampling of reactor, storage tank and other container and turn-offs operation without dead band.Wherein upward-expanding emptying valve is exactly a kind of in numerous discharging valves, and this type of discharging valve is widely used in the fields such as chemical industry, oil, metallurgy, pharmacy, agricultural chemicals, dyestuff, food processing.Generally by being arranged on valve body on the discharge port of reaction vessel, be arranged on valve plate in valve body, be fastened on the handwheel on flap, and the discharge port that is arranged on valve body lower portion forms, rotation by handwheel drive the closure of valve plate control blowing number, material flows out from being arranged on the discharge port of valve body lower portion.Traditional upward-expanding emptying valve complex structure, be not easy to processing, Operation and Maintenance is inconvenient, due to the friction of valve plate closure, easily causes the wearing and tearing of seal ring, the discharging valve making is short working life, sealability declines, and easily reveals.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of simple in structure, good seal performance, the manual upward-expansion type discharge valve of long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of manual upward-expansion type discharge valve, there is valve body, described valve body is provided with material feeding mouth and discharge port, valve body upper end is provided with valve gap, valve body lower end is provided with bracket, bracket is connected with support, is connected with handwheel seat and handwheel on support in turn; Described valve body is built-in with valve rod, and valve rod one end is provided with valve plate, between described valve gap and valve plate, is provided with seal ring, between valve rod and handwheel seat, be filled with packing layer, packing layer is provided with sealing gland outward, and the outer fixed cover of described valve rod is provided with back-up ring, and back-up ring is positioned at sealing gland below; Angle between described discharge port center line and valve rod center line is 30-50 °.When valve plate is closed, back-up ring has stopped the excessive closure of valve plate, has alleviated the wearing and tearing to valve plate and seal ring, is conducive to the prolongation in valve plate and seal ring working life.
Further, described valve rod is threaded with handwheel seat through bracket and sealing gland.
Further, described valve body and valve gap are bolted to connection, and sealing gland is fixedly connected with bracket by screw.
Further, described discharge port center line and the angle between valve rod center line are 45 °.
Further, described packing layer is teflon plate filler.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, be provided with the sealability that seal ring improves discharging valve, because valve rod is provided with back-up ring, when valve plate is closed, back-up ring has stopped the excessive closure of valve plate, is conducive to the prolongation in valve plate and seal ring working life, discharging valve is easy to processing, convenient operating maintenance simultaneously.
