Description
Technical field
This utility model relates to a kind of discharge valve, is specifically related to a kind of combination type discharge valve.
Background technology
It is required for avoiding the leakage of material when the transport of groove tank car and handling height corrosion or high toxicity material.When handling, generally say one end link slot tank car of discharge valve, the other end fixed installation device for discharging of discharge valve.When discharging, if as operational error, the end of discharge valve departs from, then will cause groove tank car end or the leakage of storing end, pollute.
Summary of the invention
For solving deficiency of the prior art, the purpose of this utility model is to provide a kind of combination type discharge valve.
The technical scheme that this utility model is taked is:
A kind of combination discharge valve, including valve casing, the leading inlet of valve casing is inclined upwardly, leading inlet end face is flange face, survey in leading inlet and bottom valve is installed, the back segment of valve casing is provided with butterfly valve, the rear end of valve casing is discharging joint, dust cap is installed on joint, described bottom valve includes valve plate, the crank mechanism opening valve plate and the valve rod that the pressing plate being installed on leading inlet end face coordinates with valve shell cavity, and valve rod is vertically installed in the upper end face of valve plate, and pressing plate is provided with the pilot hole coordinated with valve rod, being cased with spring on valve rod, spring is squeezed between valve plate and pressing plate；Described crank mechanism is arranged at the lower section of valve plate.
Further, described crank mechanism includes rotating shaft, crank and push rod, described rotating shaft one end warp beam sleeve is connected with the axis hole in valve casing, the sealed assembly of the rotating shaft other end is connected with the shaft hole matching on valve casing, on the external part of rotating shaft, spanner is installed, crank is fixedly installed in rotating shaft, and the head of crank is hinged with push rod, the free end of push rod and the bottom surface of valve plate.
Further, the bottom surface of described valve plate is provided with conical cavity, and the free end of described push rod stretches in conical cavity.
Further, described black box includes two groups of filler assemblies and one group of sealing ring, and sealing ring is arranged between two groups of filler assemblies.
Yet further, the valve casing outer wall between described bottom valve and butterfly valve is provided with a circle cutting groove.
After taking above technical scheme, combination valve uses bottom valve and butterfly valve concatenation in of the present utility model having the beneficial effect that, bottom valve controls input, butterfly valve control output end, and two ends control respectively, can better control in use, prevents from revealing.In an emergency situation, combination valve can disconnect from middle cut-off port, and butterfly valve cuts out, it is to avoid continuing to put out of outfan, and butterfly valve cuts out and avoids the backflow of input to overflow.This method simple in construction, practical reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural scheme of mechanism of crank mechanism.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further described:
As shown in the figure, a kind of combination discharge valve, including valve casing 1, the leading inlet of valve casing 1 is inclined upwardly, leading inlet end face is flange face 2, survey in leading inlet and bottom valve 3 is installed, the back segment of valve casing is provided with butterfly valve 4, valve casing outer wall between bottom valve 3 and butterfly valve 4 is provided with a circle cutting groove 5, the rear end of valve casing is discharging joint 6, dust cap 7 is installed on joint 6, described bottom valve 3 includes the pressing plate 31 being installed on leading inlet end face, the valve plate 32 coordinated with valve shell cavity, open crank mechanism and the valve rod 33 of valve plate, valve rod 33 is vertically installed in the upper end face of valve plate 32, pressing plate 31 is provided with the pilot hole coordinated with valve rod 33, spring 34 it is cased with on valve rod 33, spring 34 is squeezed between valve plate 32 and pressing plate 31；Crank mechanism includes rotating shaft 35, crank 36 and push rod 37, described rotating shaft 35 one end warp beam sleeve is connected with the axis hole in valve casing, the sealed assembly of rotating shaft 35 other end is connected with the shaft hole matching on valve casing 1, described black box includes two groups of filler assemblies and one group of sealing ring, and sealing ring is arranged between two groups of filler assemblies.Being provided with spanner 38 on the external part of rotating shaft 35, crank 36 is fixedly installed in rotating shaft 35, and the head of crank 36 is hinged with push rod 37, and the bottom surface of described valve plate 32 is provided with conical cavity 30, and the free end of described push rod 37 stretches in conical cavity 30.
