Abstract
The utility model discloses a fish inlet of a fish suction pump, comprising a casing and a rubber valve plate, wherein the casing is hollow and provided with two openings at the two ends, one end of the rubber valve plate is fixedly arranged in the casing, the rubber valve plate seals one of the two openings, the fish inlet also comprises a barrier part, the barrier part is arranged in the casing, when the fish inlet is used, the rubber valve plate overturns until the barrier part supports the rubber valve plate and prevents the rubber valve plate from further rotating. A gap is formed between the rubber valve plate and the inner wall of the casing, the gap can prevent the rubber valve plate from being clamped on the inner wall of the casing, and besides, the tilt angle of the rubber valve plate is not excessively large, and the service life of the valve plate is prolonged.
Description
Technical field
The utility model relates to a kind of fishpump, relates in particular to a kind of fish inlet for fishpump.
Background technology
Fishing boat is provided with for the fishpump of the fish of fishing in the fishing net being delivered on the ship, and referring to Fig. 1, fishpump is driven by motor 100, and motor 100 links to each other with rotating shaft 102 by shaft coupling 101, and rotating shaft 102 links to each other with impeller 103.When motor rotated, impeller 103 was rotated in housing 104, produces negative pressure at fish inlet 105 places of fishpump, thereby the fish in the fishing net is drawn in the housing 104, and discharge from fish outlet 106 by impeller 103 backs.
Be provided with a rubber one-way cock at the fish inlet place of fishpump, the rubber one-way cock has played crucial effect in fishpump work.When fishpump vacuumizes work, require rubber one-way cock and casing valve port to fit tightly, can not leak gas, leak.During the work of fishpump clingfish, fish and water enter in the housing behind the rubber valve plate that backs down check valve.
The fish inlet of having showed a kind of existing fishpump among Fig. 2 comprises the housing 1 of a hollow both ends open, and the opening 11 of housing 1 bottom is sealed by a rubber valve plate 2, and one section of described rubber valve plate is fixed on housing 1 inwall.Referring to Fig. 3, this fish inlet in use, the angle that rubber valve plate 2 is easy to overturn is excessive, is stuck on the inwall of housing 1, especially rubber valve plate 2 is stuck on the inwall at housing 1 top easily.Rubber valve plate 2 frequent flip angles are excessive in addition, also occur distortion after the root of rubber valve plate 2 bends repeatedly easily.
Summary of the invention
The utility model provides the fish inlet of fishpump at deficiency of the prior art, can prevent that rubber valve plate is stuck on the inner walls, has also prolonged the service life of valve block in addition.
For solving the problems of the technologies described above, the utility model is solved by following technical proposals: the fish inlet of fishpump, comprise housing and rubber valve plate, respectively there is an opening at described housing hollow and two ends, in the fixing described housing of described rubber valve plate one end, and described rubber valve plate seals one of them described opening, also comprise a block piece, described block piece is arranged in the described housing, during use, the rubber valve plate upset props up described rubber valve plate up to described block piece, stops the further rotation of rubber valve plate.At this moment described rubber valve plate and described inner walls have the gap, and this gap can prevent that rubber valve plate is stuck on the inner walls, and the flip angle of rubber valve plate can be not excessive yet in addition, prolonged the service life of valve block.
In the technique scheme, concrete, described block piece is pin, and described pin is welded on the inwall of described housing.The barrier structures of this kind structure is simple, is the preferred a kind of block piece of the utility model.
In the technique scheme, preferred, described rubber valve plate one end is by being bolted in the described housing.The connected mode of this kind rubber valve plate connects reliably, and for convenience detach and installation.
The beneficial effects of the utility model are: during use, the rubber valve plate upset props up described rubber valve plate up to described block piece, stops the further rotation of rubber valve plate.At this moment described rubber valve plate and described inner walls have the gap, can prevent that rubber valve plate is stuck on the inner walls, and the flip angle of rubber valve plate can be not excessive yet in addition, prolonged the service life of valve block.
Description of drawings
Fig. 1 is the schematic diagram of fishpump.
Fig. 2 is the schematic diagram of existing fish inlet.
Schematic diagram when Fig. 3 uses for existing fish inlet.
Fig. 4 is the schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 4, the fish inlet of fishpump comprises housing 1, rubber valve plate 2 and sells 3, housing 1 hollow, the upper end of housing 1 has an opening 12, and the lower end of housing 1 has an opening 11.Rubber valve plate 2 is fixed in the housing 1 by bolt 4.And rubber valve plate 2 seals one of them opening 11, also comprises a pin, and block piece is arranged in the housing 1, and when block piece propped up rubber valve plate 2, rubber valve plate 2 was 84 ° of angles with opening 11 place end faces, and rubber valve plate 2 has the gap with housing 1 inwall.
During beginning, rubber valve plate 2 seals described opening 11.During use, the rotation of the impeller of fishpump, air is discharged in housing, causes the air pressure in the fish inlet to reduce, and under the atmospheric effect in the external world, upwards upset of rubber valve plate 2 props up rubber valve plate 2 up to pin 3, stops the further rotation of rubber valve plate 2.At this moment rubber valve plate 2 has the gap with housing 1 inwall, and this gap can prevent that rubber valve plate 2 is stuck on housing 1 inwall, and the flip angle of rubber valve plate 2 can be not excessive yet in addition, prolonged the service life of valve block.
