Description
Technical field
The present invention 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 turns off operation without dead band.Wherein upward-expanding emptying valve is exactly the one in numerous discharging valve, and this type of discharging valve is widely used in the fields such as chemical industry, oil, metallurgy, pharmacy, agricultural chemicals, dyestuff, food processing.General by the valve body be arranged on the discharge port of reaction vessel, the valve plate be arranged in valve body, the handwheel be fastened on flap, and the discharge port being arranged on valve body lower portion is formed, by the rotation of handwheel drive valve plate closed control blowing number, material flows out from the discharge port being arranged on 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 that valve plate is closed, easily cause the wearing and tearing of seal ring, the discharging valve made is short for working life, and sealability declines, and easily reveals.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides that a kind of structure is simple, good seal performance, the manual upward-expansion type discharge valve of long service life.
The technical solution adopted for the present invention to solve the technical problems is: 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, support is connected with handwheel seat and handwheel in turn; Described valve body is built-in with valve rod, and valve rod one end is provided with valve plate, is provided with seal ring between described valve gap and valve plate, packing layer is filled with between valve rod and handwheel seat, be provided with sealing gland outside packing layer, described valve rod fixed sleeves is provided with back-up ring, and back-up ring is positioned at below sealing gland; Angle between described discharge port center line and valve rod center line is 30-50 °.When valve plate closes, back-up ring blocks the excessively closed of valve plate, alleviates 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, the angle between described discharge port center line and valve rod center line is 45 °.
Further, described packing layer is teflon plate filler.
The invention has the beneficial effects as follows: the present invention is 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 closes, back-up ring blocks the excessively closed of valve plate, be conducive to the prolongation in valve plate and seal ring working life, discharging valve is easy to processing simultaneously, convenient operating maintenance.
