The application is achieved in that a kind of with valve position instruction structure swing check valve, including valve body, in valve body
Arranging supplied gas or the passage of liquid flowing, arrange valve seat, arrange flap on valve seat on passage, flap can be joined with valve seat
Closing the open and close state realizing passage, flap is connected in contactless position indicator by rigid link, contactless position
Indicator is arranged on outside valve body.
As above a kind of indicate structure swing check valve with valve position, wherein, described rigid link include with
Flap fixes the rocking arm of connection, and one end of this rocking arm is fixed on valve body by bearing pin, and rocking arm can drive flap around pin
Axle rotates, and fixing with connecting rod and valve position indicating arm the most successively on rocking arm is connected, and the rocking arm of rotation can drivening rod and valve position refer to
Showing that bar moves, also set up valve gap on valve body, valve gap arranges through hole, valve position indicating arm is through the through hole on valve gap and noncontact
Formula position indicator is fixing to be connected.
As above a kind of with valve position instruction structure swing check valve, wherein, indicating arm top, valve position is provided with
Inductive head, when flap standard-sized sheet, valve position indicating arm arrives highest point, inductive head and contactless position indicator trigger action,
Achieve the position monitoring during standard-sized sheet of valve position, and on-off model feedback can be directly obtained.
As above a kind of with valve position instruction structure swing check valve, wherein, at valve position indicating arm through valve gap
Position nut 9 can also be set, to ensure the connective stability of valve position indicating arm.
The effect of the application is: instruction structure in valve position described in this patent, by connecting rod frame for movement and contactless position
Put the integrated mode of indicator, it is achieved that to the position monitoring during standard-sized sheet of valve position, and valve position signal feedback can be directly obtained.It is excellent
Point is simple and reliable for structure, turn avoid running through and the risk of dielectric leakage of stress metal border.

Detailed description of the invention
Below in conjunction with the accompanying drawings the technical scheme of the application is elaborated.
As shown in Figures 1 and 2, a kind of with valve position instruction structure swing check valve, including valve body 1, at valve body 1
The middle passage arranging supplied gas or liquid flowing, arranges valve seat 2 on passage, arranges flap 3 on valve seat 2, and flap 3 can be with
Valve seat 2 coordinates the open and close state realizing passage, and flap 3 is connected in contactless position indicator 10 by rigid link, non-
It is outside that contact position indicator 10 is arranged on valve body 1.
Described rigid link includes the Rocker arm 4 that be connected fixing with flap 3, and one end of this Rocker arm 4 is fixed on by bearing pin 5
On valve body 1, and Rocker arm 4 can drive flap 3 to rotate around bearing pin 5, solid with connecting rod 7 and valve position indicating arm 8 the most successively on Rocker arm 4
Fixed connecting, the Rocker arm 4 of rotation can drivening rod 7 and valve position indicating arm 8 move, and also sets up valve gap 11, valve gap 11 on valve body 1
On through hole is set, valve position indicating arm 8 is fixed with contactless position indicator 10 through the through hole on valve gap 11 and is connected.
Indicating arm 8 top, valve position is provided with inductive head, and when flap 3 standard-sized sheet, valve position indicating arm 8 arrives highest point, sensing
Head and contactless position indicator 10 trigger action, it is achieved that to the position monitoring during standard-sized sheet of valve position, and can directly obtain out
Pass amount signal feedback.
The position passing valve gap 11 at valve position indicating arm 8 can also arrange nut 9, to ensure the connection of valve position indicating arm 8
Stability.
It addition, the technical scheme of the application is also equipped with following characteristics:
(1) valve position instruction linkage
