Brief description of the drawings
A kind of cross-sectional view for reverse open regulating valve that Fig. 1 provides for the utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the utility model provides a kind of reverse open regulating valve, including main valve body 1, valve cover 2, cylinder
Support 14, axle sleeve 12, valve seat 5, valve seat set 4, valve shaft 7, valve element 8 and cylinder 16, the side of the main valve body 1 offers charging aperture
A, bottom offers discharging opening B, and cross-sectional area of the cross-sectional area less than the main valve body 1 of the charging aperture A.
The valve seat set 4 is fixed on the bottom of the main valve body 1 by bolt 20.
The first sealing gasket 6 is provided between the valve seat set 4 and the main valve body 1.
The valve cover 2 is assemblied in the top of the main valve body 1, and is sealed by the second sealing gasket 3.
The axle sleeve 12 is located at the center of the valve cover 2, and valve shaft 7 is assemblied in the axle sleeve 12；The valve shaft 7 it is upper
End connection shaft coupling 13, is coupled, valve shaft 7 can be slided up and down by shaft coupling 13 with cylinder 16.
The periphery of the valve shaft 7, which is provided with, is used for sealedly flexible sealing shroud 10, and the flexible sealing shroud 10 passes through axle sleeve 12
It is fixed and wraps the periphery in the axle sleeve 12 and the valve shaft 7, the contact for completely cutting off ore pulp and the valve shaft 7.
The periphery of the flexible sealing shroud 10 is provided with a protecting pipe 11, and the protecting pipe 11 is fixed on the valve cover 2,
For protecting ore pulp directly washing away to the sealing shroud 10 that stretches.
The cylinder 16 is assemblied on the air cylinder support 14, and coaxial with the valve shaft 7 and valve seat 5；The valve seat 5 is filled
Covered assigned in the valve seat in 4, and the endoporus of the valve seat 5 is in truncated cone-shaped；The valve element 8 is assemblied in the lower end of the valve shaft 7, and
Coordinate in the endoporus of the valve seat 5 with the valve seat 5 formation；During closed mode, cylinder 16 is ejected, and promotes valve shaft 7, valve element
8 are pressed in valve seat 5；During open mode, cylinder 16 is retracted, and drive is risen by valve shaft 7 with movable valve plug 8, makes valve element 8 and valve seat 5
Between form gap, realize flow regulation control, meanwhile, ore pulp flows to discharging opening B from the gap；The stroke of the cylinder 16
Controlled by the cylinder locator 17 being attached thereto.
The charging aperture A is connected with ore pulp feed pipe A00 so that the main valve body 1 is fixed on institute by fastener 19
State on ore pulp feed pipe A00.
It is provided with below the discharging opening B between discharge pipe, and the discharging opening B and the discharge pipe provided with a buffering
Device；The buffer unit is connecting tube or buffer barrel.
Charging aperture A of the ore pulp through the side of main valve body 1 enters in main valve body 1, along the gap opened between valve element 8 and valve seat 5,
From bottom outflow.Because the cross-sectional area of main valve body 1 is more than the cross-sectional area of the charging aperture A, i.e., the space of described main valve body 1
More than charging aperture A space, when ore pulp is flowed into main valve body 1 from charging aperture A, in the absence of the catwalk diminished suddenly, just
High-speed jet will not be produced to damage main valve body 1；, can be true and flow velocity of the ore pulp in main valve body 1 is less than feed pipe A00
The service life for protecting valve body is longer.Because valve seat 5 and valve element 8 are designed in inverted round stage, between fluid passes through between valve element 8 and valve seat 5
During gap, its flow direction be from it is upper diagonally downward, it is this while also eventually collided together from four circumferential center flows
The collision of fluid itself can also eliminate its very big a part of energy, and fluid flow direction is become downward, flow out regulating valve.
Meanwhile, when needing to change valve seat 5 with the grade consumable accessory of valve element 8, only need first to retract cylinder 16, allow valve element 8 to rise
Depart from valve seat 5, need to only remove the bolt 20 being locked on valve seat set 4, so that it may laterally extract valve seat set 4 together with valve seat 5 out, this
When, then cylinder 16 is released, allow valve element 8 to stretch out outside main valve body 1, just detachable bottom spool 8, after checking, changing the valve element 8 of valve seat 5,
Just it can reassemble, whole disassembly process simple and fast.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
