The valve clack support sets up in bellied access hole inner wall, can guarantee the perfect laminating of valve clack and pipeline, and the clamping device adaptation that stretches out on the locking knot on the valve clack can and the top valve body inner wall for the valve clack can not drop.
Further, clamping device includes the fixed first backup pad in one side to and the second backup pad that can move about with first backup pad complex, the valve body inner wall is exposed to second backup pad one end, the other end and the bracing piece one end swing joint that is located the valve body outside, the bracing piece other end is equipped with the seal cover and inserts the water storage pipe that is located the valve body outside, the water storage pipe inserts the valve body and flushes with the inner wall of valve body, the water storage pipe is located the water storage port limit of valve body inner wall and has the movable sealing plate that can follow the direction of intaking closing cap water storage port.
When water current entered along the direction of intaking, rivers lifted the valve clack for locking on the valve clack is detained and can be inserted clamping device, and is blocked by clamping device's circular draw-in groove, and the spring was in the state of relaxing this moment, and the rivers lift the flagging movable sealing plate naturally, and the water that makes to get into the retaining pipe is less, can't promote the bracing piece, and the valve clack is kept by the state of clamping device centre gripping.
When rivers flow back along the direction of intaking, rivers promote the activity seal pot and fall back, make rivers get into the retaining pipe, there is enough big water pressure to promote the bracing piece, make the contained angle change between bracing piece and the second backup pad, make the spring tighten up, simultaneously at the middle part pivot of second backup pad, make the circular draw-in groove of constitution open between second backup pad and the first backup pad, the valve clack leaves clamping device under the promotion of rivers, and seal the water inlet under the effect of rivers, the initial position is replied under the effect of spring to the second backup pad.
For better water flow pushing the valve flap, it can be provided that the length of the valve flap exceeds the second support plate.
Further, the middle part of the second supporting plate is fixed on the valve body through a rotating shaft.
Further, one side of the second support plate close to the support rod is connected with a spring fixed on the valve body.
After the clamping device clamps the locking buckle, the spring is just in a relaxation state, the spring is stretched/tightened firstly in the process that the locking buckle enters, the spring enters the relaxation state again after the locking buckle enters the circular clamping groove, the second supporting plate is opened firstly in the process that the locking buckle leaves, the spring is stretched/tightened, and the spring relaxes again after the locking buckle is separated, so that the second supporting plate is restored to the original position.
Further, when the valve clack naturally droops, the valve body is provided with a clamping groove which can be matched with the naturally drooped valve clack.
Further, first backup pad and second backup pad face in opposite directions all have a semicircle draw-in groove, and the combination is the circular draw-in groove that can the centre gripping locking detain jointly.
Has the advantages that: compared with the prior art, the utility model:
adopt the utility model discloses a design, the valve clack can be by the clamping part centre gripping for the valve clack gravity need not to be overcome always to route in-process rivers.
Drawings
FIG. 1 is a schematic structural view of the clamped valve flap of the present invention;
fig. 2 is a schematic structural diagram of the valve flap of the present invention after the valve flap is separated from the clamping device.
Detailed Description
The following detailed description is to be read with reference to the drawings and the accompanying detailed description.
Example 1
As shown in figures 1 and 2, a locking-type check valve that returns to separates, including valve body 1, valve body 1 has water inlet 2, delivery port 3 and access hole 4, and access hole 4 is protruding from valve body 1, and the inner wall of bellied access hole 4 has the support that can set up valve clack pivot 5, and the bottom of valve clack 6 has the locking of orientation direction of intaking and detains 7, and valve clack 6 lifts up the back along the direction of intaking and is located the clamping device adaptation on the valve body 1 inner wall.
The valve clack 6 support sets up in 4 inner walls of bellied access hole, can guarantee the perfect laminating of valve clack 6 and pipeline, and the locking on the valve clack 6 is detained 7 and is stretched out clamping device adaptation on can and the 1 inner wall of top valve body for valve clack 6 can not drop.
