Description
Technical field
The present invention relates to a kind of tight type pipeline blind plate, belong to blind plate technical field.
Background technology
Blind plate is a kind of part for blocking pipe mouthful.At present, in each neck of industry-by-industry
Blind plate has all been used in the pipeline in domain.In chemical industry, some are often touched right
Environment has pollution, the liquid being hazardous to the human body, and the conveying of these liquid is particularly careful.Existing
Have in technology, blind plate is only connected by bolt with pipeline, although in operation and dismounting very
Simply, but when the pressure of the liquid of conveying is excessive, it is easy to cause huge to blind plate
Impact so that these have pollution to environment, and the liquid being hazardous to the human body can flow out pipeline, this
Imponderable injury will be caused to environment and the mankind.So fastness and sealing of blind plate
It is very important.
Therefore, it should a kind of new technical scheme is provided and is solved the above problems.
The content of the invention
The present invention provides a kind of tight type pipeline blind plate.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of tight type pipeline blind plate, including blind plate body, blind plate body end face are provided with solid
Determine boss, fixing lug boss periphery is provided with boss fixed block, and boss fixed block is uniformly located at fixation
In outer wall of boss, it is provided with outside through hole between the outward flange of fixing lug boss outward flange and blind plate body
Circle, through hole outer ring is provided with through hole.
The relevant content of above-mentioned technical proposal is explained as follows：
In above-mentioned technical proposal, sealing ring is provided between fixing lug boss outward flange and through hole outer ring
Groove.
Further technical scheme, blind plate body, fixing lug boss and boss fixed block one is pressed
System is formed.
Preferably, seal groove section is V-arrangement.
Preferably, seal groove bottom is provided with snubber elastomeric packing ring.
Because above-mentioned technical proposal is used, the present invention has following excellent compared with prior art
Point：
Overall structure is simple, and manufacture craft is easy, reduces the limitation of connection, extends
Service life, also saves cost, and connection is reliable, increased fastness, the sealing of blind plate
Property and anti-pressure ability.
Brief description of the drawings
Accompanying drawing 1 is schematic diagram of the present invention.
Accompanying drawing 2 is the A-A sectional views of Fig. 1 of the present invention.
In the figures above：1st, blind plate body；2nd, fixing lug boss；3rd, boss fixed block；4、
Through hole outer ring；5th, through hole；6th, seal groove；7th, snubber elastomeric packing ring.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Embodiment one：
As illustrated in fig. 1 and 2, a kind of tight type pipeline blind plate of the invention, including blind plate sheet
Body 1, the end face of blind plate body 1 is provided with fixing lug boss 2, and the periphery of fixing lug boss 2 is provided with boss
Fixed block 3, boss fixed block 3 is uniformly located on the outer wall of fixing lug boss 2, fixing lug boss 2
Through hole outer ring 4 is provided between the outward flange of outward flange and blind plate body 1, is set on through hole outer ring 4
There is through hole 5, blind plate body 1, fixing lug boss 2 and the one compacting of boss fixed block 3 are formed,
Seal groove 6, seal groove 6 are provided between the outward flange of fixing lug boss 2 and through hole outer ring 4
Section is V-arrangement, and the bottom of seal groove 6 is provided with snubber elastomeric packing ring 7, and overall structure is simple,
Manufacture craft is easy, reduces the limitation of connection, extends service life, also saves
Cost, connection is reliable, increased fastness, sealing and the anti-pressure ability of blind plate.
The above embodiments merely illustrate the technical concept and features of the present invention, ripe its object is to allow
The personage for knowing technique will appreciate that present disclosure and implement according to this, can not be limited with this
Protection scope of the present invention processed.All equivalence changes made according to spirit of the invention are repaiied
Decorations, should all be included within the scope of the present invention.
