Description
Technical field
The present invention relates to a kind of check-valves, are specifically related to a kind of built-in revolve of pin shaft and open check-valves
Background technique
Check-valves is opened in existing rotation, and common structure is to connect the pin shaft of rocking bar there are pin shaft hole on valve body from valve body
Outer surface penetrates valve inner through pin shaft hole, and pin shaft hole need to be sealed with gasket and plug screw, increases the hidden danger of valve body leakage.
In addition there are some rotations to open check-valves, by the way that relative complex structure is arranged, forms the built-in of pin shaft, but increase entire valve
Number of parts, production cost gets higher.
Summary of the invention
A kind of built-in revolve of pin shaft that be designed to provide of the application opens check-valves, and the pin shaft for connecting rocking bar is fully mounted to
Valve inner does not need to be provided with pin shaft hole on valve body, does not need more additionally to increase other parts to realize the built-in of pin shaft.?
While guaranteeing valve body overall sealing performance, the economy of the manufacturing is also improved.
The technical scheme is that check-valves is opened in a kind of built-in rotation of pin shaft, including valve body, valve seat, flap, rocking bar,
Locking nut, valve deck, pin shaft, stud, nut, valve body is interior to be equipped with the first groove and the second groove, and pin shaft is equipped with the first pin shaft
Boss and the second pin shaft boss, the position of the first pin shaft boss and the first matching grooves, the position and second of the second pin shaft boss
Matching grooves.
Check-valves is opened in the built-in rotation of a kind of pin shaft as described above, wherein and valve deck is equipped with the first compression bar and the second compression bar,
First compression bar is aligned with the first pin shaft boss, and the second compression bar is aligned with the second pin shaft boss.
Remarkable result of the invention is: built in rocking bar pin shaft, without the expense axis hole on valve body, reducing the leakage of valve body
Point improves valve overall sealing performance.

Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown in Figure 1, it includes valve body 1, valve seat 2, flap 3, rocking bar 4, locking screw that the built-in rotation of pin shaft, which opens check-valves mainly,
Female 5, valve deck 6, pin shaft 7, stud 8, nut 9.
As shown in Fig. 2, being equipped with the first groove 11 and the second groove 12 inside valve body 1.
As shown in figure 3, pin shaft 7 has the first pin shaft boss 71 and the second pin shaft boss 72.
As shown in Figure 4 and Figure 5, valve deck 6 is equipped with the first compression bar 61 and the second compression bar 62.
As shown in fig. 6, valve seat 2 and valve body 1 are welded to connect when assembly, flap 3 connect with rocking bar 4 and by locking nut 5
Fastening.In the hole that pin shaft 7 is passed through to rocking bar 4, the assembly that pin shaft 7 and rocking bar 4 and flap 3 connect into then is placed in valve body
1 inside.At this point, the first pin shaft boss 71 is placed in the first groove 11, the second pin shaft boss 72 is placed in the second groove 12.
When valve deck 6 is installed, the first compression bar 61 is aligned with the first pin shaft boss 71, and contact compression, the second compression bar 62 and the second pin shaft
Boss 72 is aligned, and contacts compression, and valve deck 6 is fastenedly connected with valve body 1 by stud 8, nut 9.
Above-mentioned specific embodiment is used to illustrate the present invention, rather than limits the invention, of the invention
In spirit and scope of protection of the claims, to any modifications and changes that the present invention makes, protection model of the invention is both fallen within
It encloses.
