Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model cross divider left view；
Fig. 3 is the utility model stainless steel fine-structure mesh plate right view.
In figure: 1 housing, 2 check frames, 3 spring eyes, 4 compressed springs, 5 rounded stops, 6 reverse stopping plates, 7 stainless steel fine-structure mesh plates,
8 cross dividers.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of circulation mouth piece non-return valve device, including
Housing 1, the inner cavity of the housing 1 are equipped with check frame 2, and the surface of the check frame 2 laterally offers bullet in front and back side up and down
Spring hole 3 is movably set with compressed spring 4 in the spring eye 3, and the right end of the compressed spring 4 is welded with rounded stops 5, and
Rounded stops 5 are located at the right side of spring eye 3, and the left end of four compressed springs 4 is respectively welded at the upper and lower of 6 right side of reverse stopping plate
The inner cavity right side of front and back end, the housing 1 is welded with stainless steel fine-structure mesh plate 7, and cross gear is equipped on the left of the inner cavity of the housing 1
Frame 8.
Wherein, the housing 1, check frame 2, rounded stops 5, reverse stopping plate 6 and cross divider 8 are stainless steel structure, by force
Degree is high, is not easy to get rusty, be bolted between the housing 1 and check frame 2, stable connection, convenient disassembly, and housing 1 with
Junction between check frame 2 is equipped with seal washer, increases leakproofness, passes through bolt between the housing 1 and cross divider 8
Fixed, easy to connect and stable, the outer wall of the housing 1 is bonded with rubber seal, increases housing 1 and circulation mouth piece inner wall
Between leakproofness.
Working principle: the present apparatus is inserted into circulation mouth piece inner cavity, housing 1 is fitted closely with circulation mouth piece inner cavity, so
It is inwardly inserted into bolt from circulation mouth piece outer wall using bolt afterwards, and is screwed on housing 1 and fixes, offers screw hole on housing 1, side
Just install, stainless steel fine-structure mesh plate 7 can play a role in filtering, prevent booty from entering in circulating pump, recycle pump work when generate compared with
Big suction, liquid is entered in housing 1 by recycling mouth piece, and is opened reverse stopping plate 6 to the left by the inner cavity of check frame 2, and
It is entered in circulating pump around the outside of reverse stopping plate 6, across cross divider 8, cross divider 8 limits reverse stopping plate 6, prevents
Fluid flow is excessive and damages reverse stopping plate 6 and compressed spring 4, and when circulating pump stops working, compressed spring 4 pulls reverse stopping plate
6 reset, and the inner cavity of check frame 2 is blocked, prevents liquid from flowing backwards, and rounded stops 5 can block the right side of spring eye 3, while
The right end of compressed spring 4 is limited, when component to check frame 2 and thereon carries out repair and replacement, can directly be kept off cross
Frame 8 removes, and then removes check frame 2 and repairs replacement, and simple and convenient, the right side of reverse stopping plate 6 is bonded with rubber gasket,
Increase non-return effect.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
