Description
Technical field
This utility model relates to a kind of pump housing.
Background technology
The self priming pump pump housing, including water inlet, outlet, and arranges flow switch, pressure switch etc. on the pump housing.Our state
The municipal water water standard of family is low, wherein there is much impurity, if impurity enters the pump housing, on the one hand, affect domestic water peace
Entirely, on the other hand, affecting the service life of the pump housing, so generally arranging drainage screen at pump housing water inlet, drainage screen can be to water
In impurity filter；But, only this one filtration, it is impossible to meet people's water filtration requirement to entering the pump housing.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pump housing, and it can avoid strengthening the filterability of the pump housing
Energy.
For solving above-mentioned technical problem, the technical solution of a kind of pump housing of this utility model is:
A kind of pump housing, including the pump housing, is installed on self priming pump, and the described pump housing is provided with water inlet, outlet and blade wheel chamber,
Being provided with intake tunnel between described water inlet and blade wheel chamber, be provided with a chamber in intake tunnel, the outer wall of described chamber is provided with
Installing hole, flow switch is fixed on installing hole and is in chamber, and described installing hole is through with intake tunnel；Described flow is opened
Closing the fixing seat including being screwed onto on installing hole, fixing seat has a limbers, connecting on fixing seat has cylinder seat,
Arranging spool on cylinder seat, the guide rod bottom described spool is located in cylinder seat and extends to intake tunnel, at the end of guide rod
Portion arranges jump ring, is provided with back-moving spring between described jump ring and cylinder seat；Described spool mates at the limbers of fixing seat, and
Between spool and through hole water, sealing ring is set；Being additionally provided with permanent magnet on spool, tongue tube is fixed on the pump housing and and permanent magnetism
Ferrum mates.
Described back-moving spring is volute spring, is relatively large in diameter one end and mates on cylinder seat, and diameter less one end coupling exists
On jump ring.
Described spool top is provided with bearing, and described bearing center is provided with straight tube slotted eye, and tongue tube is located in straight tube slotted eye,
Bearing outer wall is bolted with sleeve pipe, and permanent magnet is circular, is located at and is sealed between sleeve pipe and bearing.
What this utility model can reach has the technical effect that
Compared with prior art, the pump housing of the present utility model, back-moving spring is located between jump ring and cylinder seat, meanwhile,
Back-moving spring is in intake tunnel, so, when municipal administration water enters the pump housing, therein thread waits impurity will be reset bullet
Spring tangles, thus reaches the function filtered；
Compared with prior art, the pump housing of the present utility model, back-moving spring has been also prevented from thread impurity entrance flow such as grade and has opened
Close the chamber at place, it is to avoid impact on flow switch sensitivity.
Accompanying drawing explanation
Fig. 1 is the sectional view of this utility model pump housing；
Fig. 2 is the partial sectional view of this utility model pump housing.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
Referring to Fig. 1, Fig. 2, this utility model provides a kind of pump housing, including the pump housing 1, is installed on self priming pump, described pump
Body 1 is provided with water inlet 2, outlet 3 and blade wheel chamber, is provided with intake tunnel 4 between described water inlet 2 and blade wheel chamber, in water inlet
Being provided with a chamber 5 in passage 4, the outer wall of described chamber 5 is provided with installing hole 6, and flow switch is fixed on installing hole 6 and is in chamber
In room 5, described installing hole 6 is through with intake tunnel 4；Described flow switch includes the fixing seat 7 being screwed onto on installing hole 6, Gu
Having a limbers in reservation 7, connecting on fixing seat 7 has cylinder seat 8, arranges spool 9, described spool 9 on cylinder seat 8
In the guide rod 10 of bottom is located in cylinder seat 8 and extend to intake tunnel 4, jump ring 11, described card are set in the end of guide rod 10
Back-moving spring 12 it is provided with between spring 11 and cylinder seat 8；Described spool 9 mates at the limbers of fixing seat 7, and spool 7 with
Sealing ring 13 is set between through hole water；Being additionally provided with permanent magnet 14 on spool 9, tongue tube 15 is fixed on the pump housing 1 and and permanent magnetism
Ferrum 14 mates.
Described back-moving spring 12 is volute spring, is relatively large in diameter one end and mates on cylinder seat 8, and the less one end of diameter is mated
On jump ring 11.
Described spool 9 top is provided with bearing 16, and described bearing 16 center is provided with straight tube slotted eye 17, and tongue tube 15 is located at straight tube
In slotted eye 17, being bolted with sleeve pipe 18 at bearing 16 outer wall, permanent magnet 14 is circular, is located at and is sealed in sleeve pipe 18 and bearing 16
Between.
During use, current enter intake tunnel 4 from water inlet 2, and the less hydraulic pressure of a part rushes at spool 9, pushed up by spool 9
Rising, spool 9 produces the displacement of certain distance, so that create displacement difference between permanent magnet 14 and tongue tube 15, flow is opened
Close and start；Impurity in water is when entering intake tunnel 4, and the spring 12 that is reset hooks, thus reaches the effect filtered.
A kind of pump housing provided this utility model embodiment above is described in detail, used herein specifically
Principle of the present utility model and embodiment are set forth by individual example, and the explanation of above example is only intended to help to understand this
Technical scheme disclosed in utility model；Simultaneously for one of ordinary skill in the art, according to thought of the present utility model,
The most all will change, in sum, this specification content should not be construed as this reality
With novel restriction.
