The top of described connecting rod is machined with cylindrical hole, and described straight pin is inserted into this cylindrical hole
In, then described straight pin is put into together with described connecting rod " convex " word of described valve inner
Shape groove, forms revolute pair with described valve body.
The bottom surface of described cover plate is provided with steady pin, described straight pin and described connecting rod and embeds described valve
After body, it is fixed by described steady pin above it.
The bottom surface of described cover plate is positioned at the right side of described steady pin and is provided with two described columns.
Owing to have employed above technical scheme, present invention have the advantage that
Use valve body, flap, connecting rod, bolt, nut, split pin, straight pin, cover plate,
Column, steady pin combine designed swing check valve, are machined with groove, ditch in valve body
Groove shape is "convex" shaped, has conveniently realized the one-way flow of current, and the top of connecting rod adds
Work has cylindrical hole, straight pin to be inserted in this cylindrical hole, then by straight pin together with connecting rod
Put into the "convex" shaped groove of valve inner, form revolute pair, connecting rod and flap one with valve body
Rising and rotate flexibly between valve body, the bottom surface of cover plate is provided with steady pin, straight pin and connecting rod and embeds
After valve body, being fixed by steady pin above it, connecting rod will not drop in the groove of valve body,
Connect reliable, simple in construction, the bottom surface of cover plate is positioned at the right side of steady pin and is provided with two root posts,
Prevent flap and connecting rod to collide with valve body under the impact of current, improve the use longevity
Life.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be prone to effect
Understand and understand, below in conjunction with being specifically illustrating, the present invention is expanded on further.
A kind of swing check valve, including valve body 1, flap 2, connecting rod 3, bolt 4, nut
5, split pin 6, straight pin 7, cover plate 8, column 9, steady pin 10, connecting rod 3 and valve body
Connect in the pipeline of 1, be connected with bolt 4 between flap 2 with connecting rod 3, the right-hand member of bolt 4
Screwing in nut 5, the right-hand member being positioned at nut 5 on bolt 4 is provided with split pin 6, Ke Yiyou
Preventing to effect nut 5 from dropping from the right-hand member of bolt 4 after loosening, connecting rod 3 and flap 2 connect can
Leaning on, the top cover plate 8 of valve body 1 covers, and both connect with bolt is fixing,.
Being machined with groove in valve body 1, groove shape is "convex" shaped, and the top of connecting rod 3 is i.e.
Being embedded in this "convex" shaped groove, water impacts flap 2 after valve body 1 left side pipeline enters
Promoting connecting rod 3 to rotate, pipeline is opened, and water passes through in pipeline, if right side hydraulic pressure exceedes a left side
Side hydraulic pressure then connecting rod 3 and flap 2 under the effect of current and own wt by closedown of pipeline, water
Stream cut-off, has conveniently realized the one-way flow of current.
The top of connecting rod 3 is machined with cylindrical hole, and straight pin 7 is inserted in this cylindrical hole, so
After straight pin 7 is put into the "convex" shaped groove within valve body 1 together with connecting rod 3, with valve
Body 1 forms revolute pair, and connecting rod 3 can rotate together with flap 2 and between valve body 1 neatly.
The bottom surface of cover plate 8 is provided with after steady pin 10, straight pin 7 and connecting rod 3 embed valve body 1,
Being fixed by steady pin 10 above it, connecting rod 3 will not drop in the groove of valve body 1,
Connect reliable, simple in construction.
The bottom surface of cover plate 8 is positioned at the right side of steady pin 10 and is provided with two root posts 9, when flap 2
With connecting rod 3 under the impact of current during opening conduits, column 9 is possible to prevent flap 2 and connecting rod
3 collide with valve body 1 under the impact of current, cause the damage of part, improve use
Life-span.
Swing check valve disclosed in this invention, is machined with groove, groove shape in valve body 1
For "convex" shaped, having conveniently realized the one-way flow of current, the top of connecting rod 3 is machined with
Cylindrical hole, straight pin 7 is inserted in this cylindrical hole, then by straight pin 7 and connecting rod 3 one
Rise and put into the "convex" shaped groove within valve body 1, form revolute pair, connecting rod 3 with valve body 1
Rotating flexibly together with flap 2 and between valve body 1, the bottom surface of cover plate 8 is provided with steady pin 10,
After straight pin 7 and connecting rod 3 embed valve body 1, it is fixed by steady pin 10 above it, even
Bar 3 will not drop in the groove of valve body 1, connects reliable, simple in construction, the end of cover plate 8
Face is positioned at the right side of steady pin 10 and is provided with two root posts 9, it is therefore prevented that flap 2 and connecting rod 3
Collide with valve body 1 under the impact of current, improve service life.
The ultimate principle of the present invention, principal character and the present invention excellent has more than been shown and described
Point.Skilled person will appreciate that of the industry, the present invention is not restricted to the described embodiments, on
