Plate, connecting rod, cover board and valve seat, valve seat are fixed in valve body and close to water outlets, and valve seat is equipped with a through hole and is used to wear
Connecting rod, one end of connecting rod connect the first sealing plate, and connecting rod can simultaneously be moved back and forth through valve seat in valve seat, the other end of connecting rod with
Cover board connects.
Wherein, guider further includes the second sealing plate, and the second sealing plate is stacked with the first sealing plate.
Wherein, the inside edge of the water inlet of valve body is equipped with sealant rubber ring, and sealant rubber ring is fitted closely with the first sealing plate.
Wherein, the outside diameter of the second sealing plate is slightly less than the internal diameter of valve inleting water mouth.
Wherein, the outside diameter of the first sealing plate is more than the internal diameter of valve inleting water mouth.
Wherein, the outside diameter of cover board is slightly less than the internal diameter of valve body water outlet.
Beneficial effect acquired by the present invention is：The present invention provides a kind of flange form damping check valve, including valve body, sets
First flange and the second flange for being arranged on valve body water outlet end at valve inleting water mouth end, valve body is interior to be equipped with cavity, in cavity
Interior to be equipped with guider, guider is used to place current refluence, and guider includes the first sealing plate, connecting rod, cover board and valve
Seat, valve seat are fixed in valve body and close to water outlets, and valve seat is equipped with first through hole and is used to wear connecting rod, one end of connecting rod
The first sealing plate is connected, connecting rod can simultaneously be moved back and forth through valve seat in valve seat, and the other end of connecting rod is connected with cover board.By upper
Mode is stated, flange form damping check valve disclosed by the invention, equipped with guider, closing is flexible, non-return effect is good, can be effective
Abatement closes noise, and structure is novel, liquid colleague is smooth, local head loss is small.
Brief description of the drawings
Fig. 1 is a kind of cutting structure diagram of flange form damping check valve of the present invention.
Embodiment
The present invention is described in detail with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of flange form damping check valve, including valve body 3, the first method of 3 inlet end of valve body is arranged on
Orchid 1 and the second flange 2 for being arranged on 3 water outlet end of valve body, valve body 3 is interior to be equipped with cavity, in the cavity equipped with guider, is oriented to
Device is used to prevent current from flowing backwards, and guider includes the first sealing plate 5, connecting rod 4, cover board 8 and valve seat 6, and valve seat 6 is fixedly installed
In valve body 3 and close to water outlet, valve seat 6 is equipped with first through hole and is used to wear connecting rod 4, and one end connection first of connecting rod 4 is close
Sealing plate 5, connecting rod 4 is through valve seat 6 and can be moved back and forth in valve seat 6, and the other end of connecting rod 4 is connected with cover board 8.
Further, guider further includes the second sealing plate 7, and the second sealing plate 7 is stacked with the first sealing plate 5.
Preferably, the inside edge of the water inlet of valve body 3 is equipped with sealant rubber ring, and sealant rubber ring and the first sealing plate 5 are close
Fitting.
Preferably, the outside diameter of the second sealing plate 7 is slightly less than the internal diameter of 3 water inlet of valve body.
Preferably, the outside diameter of the first sealing plate 5 is more than the internal diameter of 3 water inlet of valve body.
