Specific embodiment
The application is not limited by following embodiments, can be determined according to the technical solution of the application and actual conditions specific
Embodiment.
Embodiment, as shown in Figure 1, 2, liquid ammonium nitrate pump inlet lead shower device include valve rod 1, valve body 2 and be located at valve
The flange 3 at 2 both ends of body；3 inner cavity of flange and 2 inner cavity of valve body form fluid course；Valve body 2 is equipped with valve deck 4, and valve deck 4 is equipped with
Stuffing-box 5 is fixed with valve seat 6 on stuffing-box 5；2 bottom of valve body is equipped with liquid outlet 7；1 top of valve rod sequentially passes through valve deck 4, filler
After letter 5 with valve seat 6 formation be threadedly engaged, 1 bottom of valve rod be equipped with valve rod 1 rotation move down can with liquid outlet 7 formed partition it is close
The spool of envelope.
1 top of valve rod is external screw thread, with 6 screw-internal thread fit of valve seat；It can realize that the axial of valve rod 1 is moved by rotation valve rod 1
It is dynamic, and the spool of bottom is driven to move up and down, so as to open liquid outlet 7 or form effective sealing with liquid outlet 7；Valve rod 1
Lower part is polished rod, and cooperation 5 inner seal ring of stuffing-box realizes sealing.
The application structure is simple, can be transformed and is made by existing gate valve.It is convenient to operate, and rotation valve rod 1 is only needed to can be achieved with
The discharge of liquid ammonium nitrate or normal conveying；Simultaneously without purging, feed blocking can be effectively avoided, while reducing making for steam
With avoiding material splash, improve production safety stability.
As shown in Figure 1, 2, interior big outer small cricoid oblique sealing surface 8 is equipped at liquid outlet 7, spool includes being fixed on valve rod
The hemispherical hard valve head 9 of 1 bottom and the soft valve head 10 being coated on outside hard valve head 9, soft valve head 10 circular cone downward in vertex
Body shape.
The bus of the soft valve body 2 of cone shape can also be the camber line of convex.
When sealing, as valve rod 1 moves down, hard valve head 9 squeezes soft valve head 10 and forms reliable sealing with oblique sealing surface 8；Half
Spherical hard valve head 9 and oblique sealing surface 8 are tangent cooperation, and the pressure that valve head 9 hard in this way provides keeps hanging down with oblique sealing surface 8
Directly, it is more bonded between soft valve head 10 and oblique sealing surface 8 to which sealing effect is more preferable.
As shown in Figure 1, 2, liquid outlet 7 is connected with connecting tube 11 straight-through downwards.It is convenient for external pipeline in this way, liquid is discharged
Ammonium nitrate.
As shown in Figure 1, 2,2 intracavity bottom of valve body is equipped with the cutting ring that a circle is coaxially distributed with liquid outlet 7, cutting ring and valve
2 inner wall of body forms two sections of groovings, and every section of grooving includes vertical alignment surface 12 and horizontal confined planes 13；1 lower part of valve rod is along circle
Zhou Zhouxiang is evenly equipped at least three support frames 14；Corresponding hard valve head 9 presses closer soft valve head 10 in oblique sealing surface 8, and support frame 14
With screw-in cutting ring and seat is on confined planes 13.
When the rotation of valve rod 1 moves down, support frame 14 falls into rotation in grooving first, in the case where vertical alignment surface 12 acts on,
Valve head will not sideslip, can keep moving down vertically and start to seal with liquid outlet 7；After sealing, support frame 14 in limit
On face 13,1 amount of moving down of valve rod on the one hand can guarantee at this time, to guarantee sealed reliable；On the other hand can guarantee excessively to turn
Ovable valve stem 1, thus excessive compression, the soft valve head 10 of injury.
In addition when valve head seals liquid outlet 7, when carrying out the normal transport of liquid ammonium nitrate, valve rod is can be improved in support frame 14
1 intensity will not be deformed.
As shown in Figure 1, 2, mobilizable locking nut 15 being engaged with above valve seat 6 on valve rod 1.When hard valve head 9
Soft valve head 10 is pressed closer after oblique sealing surface 8, another its of locking nut 15 is tightened and is tightly attached to valve seat 6, can prevent on valve rod 1 in this way
It moves, liquid ammonium nitrate is avoided to leak out from liquid outlet 7.
As shown in Figure 1, 2, handwheel 16 is installed at the top of valve rod 1.It is operated in this way convenient for operating personnel.
The above technical characteristic constitutes the most preferred embodiment of the application, with stronger adaptability and best implementation effect
Fruit can increase and decrease inessential technical characteristic according to actual needs, to meet the needs of different situations.
