Abstract
The special wing bent pad of articulation of the present invention, relates to a kind of sealing gasket, refers more particularly to a kind of sealing gasket for articulation; Technical problem to be solved is to provide a kind of special wing bent pad of articulation that can convenient, fast replacing; The technical scheme adopting is: the matrix profile of the special wing bent pad of articulation is inc ring-type, and the triangular in shape and bottom of the section of described matrix is provided with v-depression; The outside of described v-depression is coated with closed glue; The heart portion of described matrix is provided with stretchy nylon rope; The sealing strip that the special wing bent pad of articulation does not seal for both ends open, thus while replacing more for convenience, reduced O shape circle that conventional articulation uses or the workload of asbestos rubber O shape pad replacing; Matrix material used is acrylonitrile-butadiene rubber, can ensure that like this bearing capacity of articulation and corrosion resistance are unaffected.
Description
Technical field
The special wing bent pad of articulation of the present invention, relates to a kind of sealing gasket, refers more particularly to a kind of sealing gasket for articulation.
Technical background
Articulation cry again union or by appoint, be a kind of conventional pipeline connection standard part that can facilitate installing/dismounting, for pipeline need by pipeline live connect place, turne tube can not taken pipeline apart yet. Mainly contain nut, cloud cluster, flush, sealing ring four parts compositions. By mach pipeline connection standard part after round steel or ingot mould forging molding, its type of attachment is divided socket weld and is threaded, socket weld is that steel pipe is inserted in socket joint hole and welded, therefore, be called as " socket joint articulation ", being threaded is that steel pipe is screwed in screw and connected, and therefore, is called as " threaded for union ".
The kind of articulation has isometrical and reducing. In articulation, the peaceful position that connects of cloud cluster is provided with sealing gasket, and the O shape that is shaped as of sealing gasket is enclosed, and what material was conventional has rubber, nylon or asbestos rubber. No matter adopt the O shape pad of what material, when the pipeline sealing gasket that is in operation occurs aging, be full of cracks, when damaged, just must be changed, because the cloud cluster end of articulation is provided with the seam that inserts the protrusion flushing, cause while changing O shape sealing gasket comparatively difficult; Especially when articulation two ends pipe-line equipment is relatively fixing cannot displacement and sealing gasket damages must change time, will in Renewal process, bring very large workload, the pipe-line equipment that can in Renewal process, this should not be become flexible and be dismantled all must become flexible dismounting, makes a workload of changing O shape sealing gasket originally increase several times.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical problem to be solved is to provide a kind of special wing bent pad of articulation that can convenient, fast replacing.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the matrix profile of the special wing bent pad of articulation is inc ring-type, and the triangular in shape and bottom of the section of described matrix is provided with v-depression; The outside of described v-depression is coated with closed glue; The heart portion of described matrix is provided with stretchy nylon rope.
Beneficial effect that the present invention compared with prior art has fruit is: the sealing strip that the special wing bent pad of articulation does not seal for both ends open, so while replacing more for convenience, reduced O shape circle that conventional articulation uses or the workload of asbestos rubber O shape pad replacing; Matrix material used is acrylonitrile-butadiene rubber, can ensure that like this bearing capacity of articulation and corrosion resistance are unaffected.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the structural representation of the special wing bent pad of articulation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
In figure: 1 is that matrix, 2 is that nylon rope, 3 is that closed glue, 4 is v-depression.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the matrix profile of the special wing bent pad of articulation is inc ring-type, and the triangular in shape and bottom of the section of described matrix is provided with v-depression; The outside of described v-depression is coated with closed glue; The heart portion of described matrix is provided with stretchy nylon rope.
The nylon rope 2 of matrix 1 interior setting of the present invention can increase the intensity of matrix 1; The v-depression 4 arranging on matrix 1 be in when overlap joint to reserved space, termination, the closed glue 3 applying on v-depression 4 is easily by bonding matrix 1 while overlapping for matrix 1.
When pipeline be in operation sealing gasket occur aging, be full of cracks, when damaged, just must be changed, the present invention is the sealing strip that both ends open does not seal, so in the time changing sealing gasket, choose the present invention according to the cloud cluster of articulation and the specification flushing, the length of the present invention of choosing should be greater than the girth of its installation site, the present invention is installed to behind relevant position, because its length has surplus in installation site, unnecessary length part is installed in v-depression 4, because v-depression 4 both sides are provided with closed glue 3, closed glue 3 is adhered to unnecessary length part on matrix 1, so just form the sealing ring of sealing, matrix 1 material used is acrylonitrile-butadiene rubber, pressure bearing and seal ability and the anti-erosion function that can ensure like this articulation are unaffected.
