Abstract
The utility model discloses a kind of inlet ports of self priming pump, are related to field of fluid.The inlet port includes the pump housing, check-valves and inlet tube, it is fixed with first flange disk and second flange disk on the peripheral surface of the inlet tube left and right ends, the first flange disk is fastened by bolts part and is fixed on the pump housing, and the check-valves is located at inlet tube left end endface；It is fixed with baffle ring on the left end inner wall of the inlet tube, stop member is equipped in the baffle ring.The inlet port of self priming pump described in the utility model utilizes the collective effect of stop member and baffle ring, optimizes the distribution of force of check-valves so that the uniform force of check-valves, check-valves are unlikely to deform, and improve the service life of check-valves.
Description
Technical field
The utility model is related to technical field of fluid delivery, are related to a kind of water pump more particularly to a kind of import of self priming pump
Seat.
Background technology
In self priming pump, check-valves is mounted between pump entrance and inlet port, and when self priming pump self-priming, spool is biased to water and is pumped into
Mouth side so that the air in water pump suction line is constantly reduced, and until exhausting gas, completes self-priming process, water pump input is normal
Operation；When self priming pump shuts down, spool is fallen after rise, terminates in inlet port side, is ensured to contain in the pump housing and is quantitatively drawn liquid and be not lost in.
Check-valves main material is rubber parts, the thick common iron plates of 3mm built in spool, during water pump start-stop, since spool returns
It falls on inlet port side frequently to carry out, spool edge and inlet port contact surface are smaller, it may occur that non-return valve core damage deformation is stuck in
In inlet tube, causing pump housing quantification to draw, liquid stream is lost or water pump output flow declines, and causes pump working abnormal.
Invention content
Above-mentioned in order to solve the problems, such as, the utility model proposes a kind of inlet ports of self priming pump, which can
Effectively blocking check-valves so that check-valves uniform force, check-valves are unlikely to deform, and simple and stable structure improves check-valves
Service life.
To achieve the goals above, the utility model uses following scheme, including the pump housing, check-valves, bolt and inlet tube；
The end of the pump housing is equipped with first flange disk；The outer ring of the check-valves is equipped with several through-holes；Described inlet tube or so two
It is fixed with second flange disk and third ring flange on the peripheral surface of end；The outer ring of the screw bolt passes check-valves, first flange
Disk and second flange disk, screw on fixing nut；The check-valves is located at inlet tube left end endface；In the left end of the inlet tube
It is fixed with baffle ring on wall, stop member is equipped in the baffle ring.
The first way of stop member described in the utility model：The stop member includes several first bumping posts, described
One end of first bumping post is fixed together, and the other end of first bumping post is fixed on the inner wall of the baffle ring, described several
First bumping post is generally aligned in the same plane.
The first way of stop member described in the utility model：The stop member includes several second bumping posts, described
Second bumping post is equidistantly positioned, and the both ends of second bumping post are fixed on the inner wall of the baffle ring, several second bumping posts
It is generally aligned in the same plane.
Preferably, the thickness of the baffle ring is 5mm.
Preferably, the thickness of first bumping post is 4mm.
Preferably, the thickness of second bumping post is 4mm
The utility model has the advantage of the collective effect of the stop member and baffle ring optimizes the stress of check-valves
Distribution so that the uniform force of check-valves, check-valves are unlikely to deform, and improve the service life of check-valves.
