Description
Technical field
This utility model relates to valve technology field, specifically a kind of inclination flap check-valves stuffing seal.
Background technology
At present, general pressure seal flap check-valves be by valve body, valve gap, flap, valve seat, pressure sealing ring,
Four points of rings, grading ring, support plate, bearing pin, plug screw, plug screw pad, stud, nut and lifting bolt are assembled, and join outside valve body
Making pin shaft hole and place bearing pin, bearing pin is hung flap and is realized the sealing of flap, by plug screw, plug screw pad by pin shaft hole outside valve body
Blocking, but tilt flap check-valves for high pound level, this plug screw formula seals sealing structure poor-performing, easily causes valve body
Outside puncture site external leakage, affects the overall sealing performance of valve body, use causes a lot of inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of inclination flap check-valves stuffing seal, to solve above-mentioned background
The problem proposed in technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of inclination flap check-valves stuffing seal, including valve body, valve seat, flap and bearing pin, sets in described valve body
Having valve and flap, valve body is provided with projection on the top of flap, is provided with through hole in projection, is provided with valve gap in through hole, the top of valve gap
Being provided with support plate, support plate is fastenedly connected by stud and nut with valve gap, and it is close that support plate and valve cover chamber are provided with four points of rings, pressure
Seal and grading ring；Being provided with bearing pin in described flap, bearing pin is placed in valve body through flap and two ends, bearing pin be arranged over pin
Axis hole, the outside of bearing pin is provided with lining, is provided with filler axle in pin shaft hole, and the cross section of described filler axle is "convex" shaped and filler axle
Do not contact with the top of bearing pin, between filler axle and through hole, be provided with filler, the gland being arranged over concave of filler, fill out
Material gland is installed on valve body by fastening bolt.
As further scheme of the present utility model: described filler uses woven graphite and soft graphite assembly to make.
As further scheme of the present utility model: described support plate is provided with lifting bolt.
Compared with prior art, the beneficial effects of the utility model are: by being arranged on pin shaft hole filler axle and filler pressure
Covering cooperates realizes the sealing to pin shaft hole, is filled with employing woven graphite and flexible stone in filler axle and gland simultaneously
Filler that ink assembly is made thus reach strengthen sealing property and reduce the purpose of valve body external leakage, filler axle is with bearing pin not simultaneously
Contact, the freely rotatable of bearing pin will not be had an impact, this utility model is reasonable in design, simple in construction, easy to process with become
This is cheap, is ensureing also the motion generation impact of bearing pin will not be had good market while sealing property at pin shaft hole
Generalization.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Referring to Fig. 1-3, a kind of inclination flap check-valves stuffing seal, including valve body 1, valve seat 2, flap 3 and pin
Axle 4, is provided with valve seat 2 and flap 3 in described valve body 1；Described valve body 1 is provided with projection on the top of flap 3, is provided with logical in projection
Hole, is provided with valve gap 5 in through hole, valve gap 5 be arranged over support plate 9, support plate 9 and valve gap 5 are tight by stud 10 and nut 11
It is solidly connected, is provided with four points of rings 8, pressure sealing ring 6 and grading ring 7 between support plate 9 and valve gap 5 and seals；Set in described flap 3
Having a bearing pin 4, bearing pin 4 is placed in valve body 1 through flap 3 and two ends, bearing pin 4 be arranged over pin shaft hole, facilitate taking of bearing pin 4
Putting, the outside of bearing pin 4 is provided with lining 13, is provided with filler axle 14 in pin shaft hole, the cross section of described filler axle 14 be "convex" shaped and
Filler axle 14 does not contacts with the top of bearing pin 4, the motion of bearing pin 3 will not be produced impact, be provided with and fill out between filler axle 14 and through hole
Material 15, the gland 16 being arranged over concave of filler 15, gland 16 is installed in valve body 1 by fastening bolt 17
On.
Described filler 15 uses woven graphite and soft graphite assembly to make.
Described support plate 9 is provided with lifting bolt 12.
This utility model is by the "convex" shaped filler axle 14 being arranged in pin shaft hole and the gland 16 of concave
Cooperate the sealing realized pin shaft hole, is filled with employing woven graphite and flexibility in filler axle 14 and gland 16 simultaneously
The filler 15 that graphite components is made, carrys out compressible filler 15 by screwing fastening bolt 17, thus reaches strengthen sealing property and subtract
The purpose of few valve body external leakage, filler axle 14 does not contacts with bearing pin 4 simultaneously, will not have an impact the freely rotatable of bearing pin 4.
