Description
Technical field
The utility model is related to a kind of check-valves, are specifically related to a kind of built-in revolve of axis pin and open check-valves
Background technology
Check-valves is opened in existing rotation, and common structure is to connect the axis pin 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, form the built-in of axis pin, but be the increase in entire valve
Number of parts, production cost gets higher.
Invention content
A kind of built-in revolve of axis pin that be designed to provide of the application opens check-valves, and the axis pin for connecting rocking bar is fully mounted to
Valve inner need not be provided with pin shaft hole on valve body, more need not additionally increase other parts to realize the built-in of axis pin.
While ensureing valve body overall sealing performance, the economy of the manufacturing is also improved.
The technical solution of the utility model is：Check-valves is opened in a kind of built-in rotation of axis pin, including valve body, valve seat, flap, shakes
Bar, locking nut, valve deck, axis pin, stud, nut, valve body is interior to be equipped with the first groove and the second groove, and axis pin is equipped with the first pin
Crown of roll platform and the second axis pin boss, the position of the first axis pin boss and the first matching grooves, the position of the second axis pin boss and the
Two matching grooves.
Check-valves is opened in the built-in rotation of a kind of axis pin 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 axis pin boss, and the second compression bar is aligned with the second axis pin boss.
The remarkable result of the utility model is：Built in rocking bar axis pin, without the expense axis hole on valve body, reduce valve body
Leakage point improves valve overall sealing performance.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying 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 axis pin, which opens check-valves mainly,
Mother 5, valve deck 6, axis pin 7, stud 8, nut 9.
As shown in Fig. 2, valve body 1 is internally provided with the first groove 11 and the second groove 12.
As shown in figure 3, axis pin 7 carries the first axis pin boss 71 and the second axis pin 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, when assembly, valve seat 2 is welded to connect with valve body 1, and flap 3 connect with rocking bar 4 and by locking nut 5
Fastening.In the hole that axis pin 7 is passed through to rocking bar 4, the assembly that axis pin 7 and rocking bar 4 and flap 3 connect into then is placed in valve body
1 inside.At this point, the first axis pin boss 71 is placed in the first groove 11, the second axis pin 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 axis pin boss 71, and contact compression, the second compression bar 62 and the second axis pin
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 implementation mode is used for illustrating the utility model, rather than limits the utility model,
In the spirit and scope of the claims of the utility model, to any modifications and changes that the utility model is made, all fall
Enter the scope of protection of the utility model.
