The passage of supplied gas or liquid flowing is set, valve seat is set on passage, flap is set on valve seat, flap can match somebody with somebody with valve seat
The open and close state for realizing passage is closed, flap is connected on contactless position indicator by rigid link, contactless position
Indicator is arranged on outside valve body.
One kind as described above carry valve position instruction structure swing check valve, wherein, described rigid link including with
The rocking arm that flap is fixedly connected, one end of the rocking arm are fixed on valve body by bearing pin, and rocking arm can drive flap around pin
Axle rotates, and is also fixedly connected successively with connecting rod and valve position indicating arm on rocking arm, the rocking arm of rotation can drivening rod and valve position refer to
Show that bar moves, bonnet also set up on valve body, through hole is set on bonnet, valve position indicating arm through the through hole on bonnet with it is non-contact
Formula position indicator is fixedly connected.
One kind as described above carries valve position instruction structure swing check valve, wherein, valve position indicating arm top is provided with
Inductive head, when flap standard-sized sheet, valve position indicating arm reaches highest point, inductive head and contactless position indicator trigger action,
Position monitoring during to valve position standard-sized sheet is realized, and on-off model feedback can be directly obtained.
One kind as described above carries valve position instruction structure swing check valve, wherein, in valve position, indicating arm passes through bonnet
Position nut 9 can also be set, to ensure the connective stability of valve position indicating arm.
The effect of the application is：Valve position instruction structure described in this patent, passes through connecting rod mechanical structure and contactless position
The integrated mode of indicator is put, realizes position monitoring during to valve position standard-sized sheet, and valve position signal feedback can be directly obtained.Its is excellent
Point be simple and reliable for structure, turn avoid stress metal border run through and the risk of dielectric leakage.

As shown in Figures 1 and 2, it is a kind of to carry valve position instruction structure swing check valve, including valve body 1, in valve body 1
The middle passage for setting supplied gas or liquid flowing, valve seat 2 is set on passage, flap 3 is set on valve seat 2, flap 3 can be with
Valve seat 2 coordinates the open and close state for realizing passage, and flap 3 is connected on contactless position indicator 10 by rigid link, non-
Contact position indicator 10 is arranged on outside valve body 1.
Described rigid link includes the Rocker arm 4 being fixedly connected with flap 3, and one end of the Rocker arm 4 is fixed on by bearing pin 5
On valve body 1, and Rocker arm 4 can drive flap 3 to be rotated around bearing pin 5, also solid with connecting rod 7 and valve position indicating arm 8 successively on Rocker arm 4
Fixed connection, the Rocker arm 4 of rotation can drivening rod 7 and valve position indicating arm 8 move, bonnet 11, bonnet 11 are also set up on valve body 1
Upper setting through hole, valve position indicating arm 8 are fixedly connected through the through hole on bonnet 11 with contactless position indicator 10.
The top of valve position indicating arm 8 is provided with inductive head, and when 3 standard-sized sheet of flap, valve position indicating arm 8 reaches highest point, sensing
Head and the trigger action of contactless position indicator 10, realize position monitoring during to valve position standard-sized sheet, and can directly obtain out
Pass amount signal feedback.
In valve position, the position of indicating arm 8 through bonnet 11 can also set nut 9, to ensure the connection of valve position indicating arm 8
Stability.
