Specific embodiment
Specific structure of the invention is referring to shown in Fig. 1-13.Shown in Figure 1, preventer is mainly by shell 1, side door 2, card
Hoop 3, mandril 4 and side door seal assembly 5 form.
Shown in Figure 4, there is a vertical rectangle groove 101 and 103 at 1 both ends of shell, rectangular boss 102 and 104, side door 2 with
Shell contact surface has vertical rectangle groove 201 and 203, rectangular boss 202 and 204.After shell 1 and 2 sealing surface note of side door close,
Groove 101 and groove 201 form a trapezoid space, can accommodate clip 3.
Shown in Figure 5,101,103 right side of housing groove can be vertical or inclined.201,203 left side of side door groove
It can be vertical or inclined.After shell 1 and 2 sealing surface note of side door close, groove 101 and groove 201 form a trapezoidal sky
Between, the clip 3 of fluted 301 structure can be accommodated.
Shown in Figure 4, clip 3 is U-shaped structure, and there are perpendicular grooves 301 in centre, and the width of groove 301 is equal to boss
The sum of 102 and 202 width of boss.There are boss 302 and 303 in 3 two sides of clip.The width of boss 302 and 303 is slightly less than housing groove
101 and side door groove 201.
Shown in Figure 5, clip 3 is also possible to multiple tooth groove, and the corresponding shell of side door 2 and 1 is also multiple tooth groove.Ginseng
As shown in Figure 11, there are T connected in star 308 in 3 two sides of Integral keeper, can cooperate with 405 rotary tables on installation mandril bolt 4, pass through
Two sides bolt 4 is rotated, rotary table 405 can move up and down, and Integral keeper 3 is driven to move up and down, and complete Integral keeper 3 and shell
1, the quick connection of side door 2.The multiple tooth groove of clip 3 and the mating surface 307 of shell side door can be straight, and be also possible to self-locking
Inclined-plane.
Referring to shown in Fig. 8,9,10,12,13, clip 3 can be whole, be also possible to segmented separate structure.By one
The clip 3 of measured length is divided into 2 or 3 sections, and every section of clip has a location hole to consolidate clip by screw thread with shell and side door
Fixed connection.It is vertical (Fig. 8,12) that the location hole of clip 3, which can be, is also possible to horizontal (Fig. 9,13).
Split type clip can be used positioning pin and connect with shell side door.
The bolt mandril that two sides can be used in Integral keeper is connect with shell side door.
Axial seal structure (Fig. 6) can be used in side door sealing.Sealing framework 5 is ellipsoidal structure, and side door seals 5 external seals
Each side there is the groove 501 and 502 of mountable O-ring seals on surface.After installation, the ellipse corresponding with shell of groove 501
Seal groove forms sealing, and the ovaloid seal slot corresponding with side door of groove 502 forms sealing.The spacing of groove 501 and 502 is larger, when
There are when gap between shell 1 and side door 2, groove 501,502 is remained in corresponding shell, side door sealing groove face.
End face seal structure (Fig. 7) can also be used in side door sealing.Sealing framework 6 is ellipsoidal structure, in the outside of skeleton 6
There is an oval-shaped groove 602 of mountable O-ring seals, there is mountable O shape to seal in a side end face of skeleton 6 and housing seal
The oval-shaped groove 601 of circle, the opposite side of groove 601 fluted 603, mountable rubber spring.
Side door sealing framework shape can be ellipsoidal structure, be also possible to rectangle depending on shell flashboard chamber shape
Structure.
Working principle：When needing to connect shell and side door assembly, by hydraulic control or manually control side door and shell
It shows consideration for tightly, the boss 102 on shell is bonded with side door boss 202, the groove 101 on shell and the formation of the groove 201 on side door
One U-shaped space, it is vertical by the U-shaped space that clip 3 is put into housing groove 101 and side door groove 201 is formed, then by positioning pin 4
Across clip, screwed in place pin 4 is fixed on clip 3 on shell 1 and side door 2.When there is well pressure in preventer, 3 stress of side door
It moves right, 202 right side of side door boss and 3 groove of clip, 301 right contact, 3 groove of clip, 301 left side and shell boss
102 left contacts are fixed, and clip 3 secures the position of shell and side door, complete the quick connection of shell and side door.(Fig. 2,
3,4).When there is well pressure in preventer, side door sealing 5 is radial seal, and sealing is not influenced by shell and side door gap.Side door
Skeleton 6 is pressed on the end face that shell contact with side door 6 under the action of pressure face product moment by sealing, seal not by shell and
The influence in side door gap.
When needing to separate side door assembly, take out positioning pin 4, take out clip 3 from above and below, by hydraulic control or
It manually controls and separates side door assembly with shell, complete the Quick release (Fig. 1,2,3) of shell and side door.
Rotation two sides mandril bolt driving Integral keeper can also be used to move up and down, completion clip is nibbled with shell side door
It closes.After clip and shell side door disengage, the T connected in star 308 on clip can be moved backward along rotary table 405, make the complete position of clip 3
On rear side of 2 sealing surface of side door, convenient for vertical hanged flashboard.
