A kind of Highpressure Tee expanding flat gate valve being applied in severe rugged environment, including support, handwheel, valve body, bonnet,
Valve seat, valve rod and flashboard assembly, have trapezoidal thread on the valve rod, are coordinated by the valve stem nut on trapezoidal thread and support,
The lower end of the handwheel is connected with valve stem nut, it is characterised in that the valve body is threeway shape, wherein Horizontal Exit end and import
End is in horizontal connected state, and with entrance point into plumbness, the bonnet is located at valve body top, bonnet at another vertical outlet end
End face be connected with valve body, the flashboard assembly is arranged on the middle part in valve body, including main gate-board and auxiliary gate-board, main gate-board with
The lower end of valve rod is connected, and has between main gate-board and auxiliary gate-board and coordinates inclined-plane, between major and minor flashboard by centering block and pin activity even
Connect, the flow direction at changeable Horizontal Exit end and vertical outlet end, the valve seat is arranged in the inner chamber that valve body and bonnet are formed, peace
In valve seat groove on valve body, guide plate is provided with the valve seat, the centering block is located between guide plate, for controlling to put
Block swings, and the cantilever tip is provided with valve phase indicator, and the valve phase indicator is that single-stage partial gear transmission valve position refers to
Show device, including pointer, valve position indicate disk, master gear, pinion, anti-rotation steel ball, upper lid and lower cover, the master gear to be arranged on valve
On stem nut, master gear is have two partial gears of tooth, and master gear is engaged with pinion, and finger is provided with the pinion
Pin, the pinion rotating pointer valve position that is rotatably assorted indicates disk indication valve position, is provided with the housing of the valve phase indicator
Anti-rotation steel ball, the anti-rotation steel ball prevents pinion from arbitrarily rotating with the anti-rotating hole cooperation on pinion.
As shown in Figures 1 to 7, valve body 1 is connected with the one end of bonnet 5 by bolt and nut 7, formed one have an entrance point and
Two body cavitys of the port of export, it is vertical with entrance point that one of port of export leads directly to another port of export with entrance point level.In valve body 1
On have two valve seat grooves, valve seat 2 is studded with respectively, RPTFE sealing ring 2a, and the hard sealants of built-up welding STL are studded with the valve seat 2
2c, forms soft or hard compound seal surface.Fire prevention graphite annulus 3 is press-fitted at valve seat 2 and the cooperation of valve body 1, to reach flameproof effect.In valve seat
There is major-minor flashboard to combine (i.e. flashboard assembly) between 2.There are an angle (coordinating inclined-plane), valve between main gate-board 21 and auxiliary gate-board 24
Bar 4 drives main gate-board 21 to move up and down, and auxiliary gate-board 24 is also moved therewith.When on auxiliary gate-board locating piece top to bonnet 5 or valve body 1
After positioning table, main gate-board 21 is continued to move to, and the angle between two plates makes the lengthwise movement between two flashboards be changed into transverse shifting,
So as to reach the effect of flashboard expansion, major-minor flashboard end face is close to valve seat 2, reach sealing effectiveness.When auxiliary gate-board 24 is positioned
When block leaves the positioning table on bonnet 5 or valve body 1, flashboard deadweight makes flashboard be drawn in by angle inclined-plane, now flashboard both ends of the surface
It is contactless with sealing surface of seat.Make the reduction of valve event moment of torsion.Main valve plate 21 and the upper surface of auxiliary gate-board 24 spraying STL, improve lock
Plate surface hardness and friction resistant ability.Main gate-board 21 and auxiliary gate-board 24 form two angled ramps by grinding, in flashboard expansion
There is reliable hard sealing property under state between two inclined-planes.There is centering block 22 to connect between main gate-board 21 and auxiliary gate-board 24, centering block 22
Swung with the relative position difference of two flashboards, prevent major-minor flashboard wedge dead.
Three kinds of location status of centering block 22 as shown in Figures 5 to 7, centering block 22 is contained in two pieces of guide plates 23, guide plate
23 are press-fitted on valve seat 2.The up and down action for having valve rod 4, valve rod 4 on main gate-board 21 drives main gate-board 21 to move.Valve rod 4 passes through valve
Lid 5, with having filler 8 and valve rod greasing to seal between bonnet 5, both provide reliable sealing.There are trapezoidal thread and valve rod on valve rod 4
Nut 10 coordinates, and valve stem nut 10 controls to rotate by handwheel 12, will be turned round by trapezoidal thread between valve stem nut 10 and valve rod 4
Motion is converted to the lengthwise movement up and down of valve rod.The valve stem nut 10 is assemblied on valve rack 9, and valve rack 9 is arranged on
On bonnet 5.
On the top of support 9 valve phase indicator 11 is driven equipped with single-stage partial gear.Single-stage partial gear transmission valve position
Indicator 11 indicates disk 16, master gear 20, pinion 18, anti-rotation steel ball 19 and upper lid 17a, lower cover 17b groups by pointer 15, valve position
Into.Master gear 20 is arranged on valve stem nut 10, and the rotation of valve stem nut drives master gear 20 to be driven.Master gear 20 is have 2
The partial gear of tooth, is engaged with pinion 18, the per revolution of master gear 20, and pinion 18 is rotated corresponding to two numbers of teeth
Angle.Rotational angle had both been 2x360/Z (Z is the number of teeth).Valve position indicates have two kinds of valve bit-identifies on disk 16, and opening angle passes through
Valve full action number of turns x360/Z is calculated.Valve position indicates disk 16 to be arranged on housing 17a, does not do spinning movement.Pinion
Pointer 15 is housed, pinion 18 is rotated and drives pointer 15 to rotate, and coordinates valve position to indicate the indication valve of disk 16 position on 18.To prevent secondary tooth
Wheel 18 is rotated under non-engagement state, and anti-rotation steel ball 19 is housed on housing, and anti-rotation steel ball 19 is matched somebody with somebody with the anti-rotating hole on pinion 18
Close, prevent pinion 18 from arbitrarily rotating.Valve rod 4 is moved up and down in full action process, and valve stem boot is provided with the top of handwheel 12
13, make valve rod 4 not by external environmental, the degree of protection of valve is improved, enable valve applications well in harsh operating mode bar
Part, extends life of valve.
Certainly, the present invention can also have other various embodiments, in the case of without departing substantially from spirit of the invention and its essence,
Those of ordinary skill in the art can make various corresponding changes and deformation according to the present invention, but these it is corresponding change and
Deformation should all belong to the protection domain of appended claims of the invention.
