Description
Technical field
The present invention relates to conduit coupling technical fields peculiar to vessel, and in particular to a kind of slidingtype duplex blank flange peculiar to vessel and
Application method.
Background technique
Blank flange (as shown in Figure 3) is a kind of connector used in marine piping, is mainly used for marine piping
Closure, or occasion easy to operate by mistake when for preventing pipeline connection conversion, and in maintenance of equipment for pipeline
Block conversion etc. occasions.
The structure of blank flange is normalized, and in National Standard of the People's Republic of China, " GB/T4450-2008 is peculiar to vessel blind
Slab flange " in, the specific structure of blank flange peculiar to vessel is provided, the blank flange in the standard relates generally to A type
Structure and Type B structure, wherein A type structure is single flange arrangement, and Type B structure is the integral duplex blind plate method of two flanged joints
Blue structure.For middle-size and small-size blank flange, the quantity of the bolt hole on each of which flange is most common with 4 holes, 6 holes, 8 holes.
The duplex blank flange of the Type B structure of above-mentioned standard has the following problems when in use: blank flange is carrying out
Need to dismantle when handover operation peripheral whole bolts, stays intermediate rotation bolt rotation commutation, which wastes time very much,
By taking the flange of six bolts hole as an example the duplex blank flange of 11 bolts hole (corresponding), when commutation, needs to dismount five spiral shells
Bolt.
Summary of the invention
To solve the above-mentioned problems, the present invention proposes a kind of slidingtype duplex blank flange peculiar to vessel and application method, it is intended to
The time that duplex blank flange switches over operation is saved, specific technical solution is as follows:
A kind of slidingtype duplex blank flange peculiar to vessel, left flange and right flange including integration connection, the left flange
Centered on the through-hole flange with through-hole, without the blind flange of through-hole centered on the right flange, in the duplex blank flange
The upper hopper chute for passing through flange installation bolt is offered in upper flange plane, in the lower flange of the duplex blank flange
Offered in plane for pass through flange installation bolt gliding groove, the upper hopper chute, gliding groove sliding slot centerline parallel in
Circumferential spread line upper part of left and right directions, the flange installation bolt location on the left flange, right flange respectively enters cunning
Slot is interior, its underpart respectively enters in gliding groove.
In above-mentioned technical proposal, by opening up two sliding slots on duplex blank flange, a part of flange can be made to pacify
Dress bolt is placed in two sliding slots, and the flange installation bolt in the non-sliding slot in part, and position are disassembled when as long as switching over operation
It does not need to dismantle in the flange installation bolt in two sliding slots, it is only necessary to slightly unclamp.Therefore it is effectivelying prevent switching
While maloperation, and the time of handover operation can be saved.
By taking the flange of six bolts hole as an example the duplex blank flange of 11 bolts hole (corresponding), when commutation, only needs to tear open
Fall two bolts in non-sliding slot.
One of as a preferred solution of the present invention, the circumferential spread line sliding slot with the upper hopper chute, gliding groove respectively
Center line is tangent.
Above-mentioned circumferential spread line and the tangent structure of sliding slot center line, especially suitable on single flange there are two or four
The duplex blank flange of bolt hole.
As a preferred solution of the present invention two, the circumferential spread line sliding slot with the upper hopper chute, gliding groove respectively
Center line intersection.
The structure that above-mentioned circumferential spread line intersects with sliding slot center line, especially suitable for there are four on single flange, six
Or the duplex blank flange of eight bolts hole.
As a preferred solution of the present invention three, the quantity of the flange installation bolt is 2~10.
As a preferred solution of the present invention four, the quantity of the flange installation bolt is 6.
As a further improvement of the present invention, a circle high pressure sealing is respectively arranged in the left flange and right Flange Plane
Annular copper coat, the annular copper coat are higher by 0.10~0.30mm of Flange Plane.
The setting of annular copper coat, one side can be improved in high temperature and pressure on above-mentioned left flange and right Flange Plane
In the case of seal for pipe joints reliability, on the other hand since annular copper coat is attached with duplex blank flange, with
Conventional gasket or sealing ring will not be scattered, therefore its service performance is more preferable compared to non-aging.
A kind of application method of slidingtype duplex blank flange peculiar to vessel, includes the following steps:
(1) duplex blank flange is installed:, will be in duplex blank flange according to the normally closed or normally opened original installation requirement of pipeline
Left flange or right flange installation be connected on pipeline, and with flange installation bolt be fixed, form the normally closed or normal of pipeline
Open state；
(2) pipeline conditions switch: the flange installation bolt on duplex blank flange not on upper hopper chute and gliding groove is torn open
It goes, while the flange installation bolt being located on upper hopper chute and gliding groove on duplex blank flange being unclamped, push duplex blind plate method
Orchid is moved along upper hopper chute and gliding groove, so that a flange in the duplex blank flange docked originally with pipeline is moved away from, is another
A flange is docked with pipeline, is fixed with flange installation bolt, is cut again to complete the normally closed or normally open of pipeline
It changes.
The beneficial effects of the present invention are:
First, a kind of slidingtype duplex blank flange peculiar to vessel of the invention and application method, by duplex blank flange
On open up two sliding slots, a part of flange installation bolt can be made to be placed in two sliding slots, torn open when as long as switching over operation
The flange installation bolt in the non-sliding slot in part is laid down, and the flange installation bolt being located in two sliding slots does not need to dismantle, and only needs
It slightly to unclamp.Therefore it is while effectivelying prevent switching maloperation, and can save the time of handover operation.
Second, a kind of slidingtype duplex blank flange peculiar to vessel of the invention and application method, left flange and right Flange Plane
The setting of upper annular copper coat, one side can be improved the reliability of the seal for pipe joints in high temperature and pressure, another party
Face is not easy old since annular copper coat is attached with duplex blank flange compared with conventional gasket or sealing ring
Change, will not be scattered, therefore its service performance is more preferable.
