Specific implementation method
The dismountable valve of a kind of valve plate that the present embodiment provides, structure is as Figure 1-4.
The valve includes valve pocket 1, valve plate 2, handle 3, and valve pocket 1 is arranged to cylindrical shape, and valve plate 2 is rotationally connected with valve pocket 1,
The shape contour of valve plate 2 is equal with the cross section inner surface contour of valve pocket 1, and handle 3 is connected and extended outside valve pocket 1, valve with valve plate 2
It is that at least two halves, valve plate 2 can take out from by separated valve pocket 1 that chamber 1, which divides, and the both ends of valve pocket 1 are provided with and extraneous transport pipeline
Connected threaded connection section 4.
Valve pocket 1 is divided to for the cylinder plate 11 of two symmetrical semicircular arcs, between two plates 11 at seamed edge close to each other
Provided with installation side 12.The relative face in installation side 12 is provided with the confined layer 13 for being used for improving sealing, if confined layer 13 is arranged to
The elastic strip 131 of dry linear array, the cross section of elastic strip 131 is triangle.
Threaded connection section 4 includes being located at first threaded portion 41 and the second threaded portion 42 at the both ends of valve pocket 1 respectively, and first
Threaded portion 41 is used to be directly connected to extraneous transport pipeline, passes through screw thread between the second threaded portion 42 and extraneous transport pipeline
The connection of set 43.First threaded portion 41 includes one section of external screw thread on valve pocket 1, the external screw thread and the interior spiral shell on extraneous pipeline
Line part connects.Second threaded portion 42 includes the first splicing screw thread 421 positioned at the other end of valve pocket 1, spelled positioned at close to first
Connect the extraneous pipe end at screw thread 421 second splicing screw thread 422, first splicing screw thread 421 and second splice screw thread 422 it
Between be arranged thread bush 43.The second splicing length of screw thread 422 is more than the length of valve pocket 1, and the length of thread bush 43 is less than the second splicing spiral shell
The length of line 422.
Valve plate 2 just is extended radially through with the method being threadedly coupled, handle 3 between valve plate 2 and handle 3, handle 3 is provided with spiral shell
Line, valve plate 2 are radially provided with screw.
Handle 3 is provided with the locating piece positioned at the both ends of valve plate 2, and wherein a positioning block is fixed on handle 3, another piece of positioning
It is detachably connected between block and handle 3.When valve plate 2 put just, i.e. handle 3 is pointed out vertically upward when, the one of top in locating piece
It is arc surface at the top of block, is contradicted with the inner wall smooth of valve pocket 1 so that valve plate 2 is not easily susceptible to obstruction of colliding with rotation process.
Its operation principle is：When valve needs to dismantle, changes valve plate 2, by by between valve pocket 1 and extraneous transport pipeline
Spacing removing, i.e., by the spacing removing of the screw thread of threaded connection place so that valve pocket 1 can be removed at extraneous transport pipeline.
In the process, need first at least to pass through the fluid stage in extraneous transport pipeline without fluid at the valve of preparation maintenance department.
After valve pocket 1 is removed, split, because valve pocket 1 can be by least dimidiation, therefore valve pocket 1 can be opened at least two points
One of surface area so that valve plate 2 can be taken out from valve pocket 1, to change.
The above-mentioned dismountable valve method for dismounting of valve plate, comprises the following steps：
S1, thread bush 43 is rotated, thread bush 43 is turned at the second splicing screw thread 422, now at the first splicing screw thread 421
It is spacing to be avoided；
S2, valve pocket 1 is rotated, make to be mutually disengaged between the first thread segment and extraneous transport pipeline, now valve pocket 1 can be transported with the external world
Defeated pipeline departs from；
Mode connects for screw is used between S3, two plates 11, knockout screw, exposes valve plate 2；
S4, valve plate 2 is taken out, unload dismountable locating piece, be rotated further by valve plate 2 and pulled down, after the valve plate 2 more renewed, again
Load onto locating piece.
When needing again to install valve plate 2 and valve pocket 1, first new valve plate 2 is turned to and is sheathed on handle 3, and valve plate 2
Profile contact at the locating piece being fixed on handle 3；Dismountable locating piece is attached to again and holds out against valve plate 2.This implementation
In example, dismountable locating piece uses screw, coordinates with the screwed excircle configuration of handle 3.By the handle 3 of installation
It is positioned in valve pocket 1, rotates valve pocket 1, the first threaded portion 41 and the internal thread of extraneous transport pipeline inwall is connected, be rotated further by
Thread bush 43 so that the first splicing screw thread 421, second splices screw thread 422 and is connected by thread bush 43, and now valve pocket 1 is limited completely
Position.
In addition to the implementation, the present invention can also have other implementations.It is all to use equivalent substitution or equivalent transformation shape
Into technical scheme, all fall within the protection domains of application claims.
