Description
Technical field
The utility model belongs to valve field more particularly to a kind of baiting valve.The utility model be suitable for reaction kettle or its
Its container bottom discharges the valve of solid particle or solid liquid media.
Background technique
The baiting valve for being currently used in solid particle medium is broadly divided into two classes: the first kind is upward-expanding emptying valve；Second
Class is bottom open type baiting valve.Upward-expanding emptying valve is flap up lifting material, and bottom open type baiting valve is the past decline blowing of flap.?
Reaction kettle or tank base generally use bottom open type baiting valve, as Patent No. CN201720055635.0 is used to contain solid particle
The bottom open type baiting valve of medium, including valve body, valve body includes feed inlet and the discharge port that is obliquely installed, in the case where feed inlet is corresponding
End is equipped with the valve rod being screwed on valve body, and valve stem top is equipped with spool, the valve that connection matches with top surface on spool in valve body upper end
Circle, valve rod hold out against the valve circle that spool and valve body are upwards and seal.Its major defect is: valve rod uses rising stem (RS.) structure, opens flap
When valve rod have it is biggish to bottom offset, very big installation space is needed, to bottom space measured response kettle or other tank bodies
Cause bigger difficulty；Solid particle is deposited on flap on the sealing surface of plane when blowing, causes valve clack sealing surface and valve circle
It is not closed completely, leaks, while damaging sealing surface, influence product service life.
Summary of the invention
The purpose of this utility model is to provide that a kind of installation space is small, sealing performance for disadvantage of the existing technology
Reliably, novel reaction kettle Special-purpose releasing material valve with long service life.
The technical solution of the utility model includes valve body, flap, valve rod, valve seat, bracket, handwheel, in valve outlet channel
Heart line and valve rod center line constitute inverted Y-shaped structure, and valve rod lower end is fixedly connected with the hand wheel, and valve rod top is matched with valve stem nut screw thread
It closes；It is characterized in that: valve rod is installed on bracket by bearing axial restraint, valve stem nut is equipped with radially-directed bar, the radially-directed
One end of bar is located in the axially directed slot on bracket, and flap uses hollow cylindrical structure, flap lower end inner hole wall and valve rod
Nut upper end periphery is fixedly connected；Flap upper end is cooperated using cone sealing surface and sealing surface of seat, flap outer circle
Dynamic sealing cooperates between cylinder and valve body middle chamber inner hole wall, and it is close that filler is arranged between valve external cylindrical surface and valve body middle chamber inner hole wall
Seal apparatus.
Preferably, valve seat is installed on valve body import passway by gland fixing seal, and sealing surface of seat is set to gland channel
Import.
Preferably, valve body import channel diameter is greater than valve body middle chamber diameter of bore.
Preferably, limit sleeve is fixedly mounted on the valve rod of valve stem nut side.
The utility model has the advantages that valve rod uses dark rod structure, flap has peace using cone sealing surface upward
Fill the features such as space is small, sealing surface wear is few, sealing performance is reliable, long product lifecycle.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Novel reaction kettle Special-purpose releasing material valve as shown in Figure 1, including valve body 13, flap 8, valve rod 5, valve seat 14, bracket 9,
Handwheel 2,13 exit passageway center line of valve body and 5 center line of valve rod constitute inverted Y-shaped structure, 5 lower end of valve rod and the fixed company of handwheel 2
It connects, handwheel 2 is fixedly mounted on 5 lower end of valve rod by nut 1, and 5 top of valve rod is threadedly engaged with valve stem nut 7；It is characterized in that: valve
Bar 5 is installed on bracket 9 by 4 axial restraint of bearing, and there are two bearings 4, is separately mounted to the radial convex shoulder of valve rod 5 two sides by bearing
Lid 3 is pressed in the mounting hole of bracket 9, and valve rod 5 is made to prevent from moving axially when rotating on bracket 9, and bracket 9 is equipped with connection shaft
The greasing mouth 15 held, valve stem nut 7 are equipped with radially-directed bar 16, and one end of the radially-directed bar 16 is located at the axial direction on bracket 9
It is the axial movement of valve stem nut 7 by the translating rotation of valve rod 5 in guide groove.Flap 8 uses hollow cylindrical structure, flap 8
Lower end inner hole wall is fixedly connected with 7 upper end periphery of valve stem nut, drives flap 8 to move axially by valve stem nut 7；On flap 8
End is cooperated using cone sealing surface and 14 sealing surface of valve seat, between 13 lumen inner hole wall of 8 external cylindrical surface of flap and valve body
Dynamic sealing cooperates, and stuffing seal and graphite cannula 12 is arranged between 13 lumen inner hole wall of 8 external cylindrical surface of flap and valve body, this is filled out
Material sealing device is made of filler 11 and gland 10.
Valve seat 14 is installed on 13 intake channel mouth of valve body by 17 fixing seal of gland, and 14 sealing surface of valve seat is logical set on gland 17
