Abstract
The utility model relates to a jet self-priming pump, which relates to a water pump structure, comprises a motor, an impeller and a pump body, and is characterized in that a check valve is fixed at a water inlet of the pump body, and a two-way step through hole is arranged at the center of a valve body; a right step hole is in interference fit and sleeved with a valve seat sleeve, and a sealing ring part of a rubber sealing ring valve plate one-piece piece is sandwiched between an annular step concave platform and an end surface of the water inlet of the pump body in a press fit state; the valve seat sleeve is of a tubular body, and the right end surface of a tubular piece is in an angular cut shape; the inner ring of the one-piece piece is of a circular flake-shaped valve plate that the outer diameter is slightly smaller than the inner diameter of an annular ring, and an extending one-piece piece is arranged between the circular flake-shaped upper end part and the inner wall of the upper part of the annular ring; and the circular flake-shaped center is wrapped with a circular steel piece, and after the annular ring is positioned, the circular flake-shaped left end surface and the angular cut left end surface of the valve seat sleeve are in a contact type joint state. The utility mode has the advantages that: When the pump is shut down, the valve plate automatically closes; and when the pump starts up again, a pump chamber does not need to exhaust and directly enters the normal working condition, thereby improving efficiency, doing less idle work and saving energy.
Description
Technical field:
The utility model relates to water pump structure, particularly a kind of jet-type self-priming pump.
Background technique:
Existing jet-type self-priming pump structure is made up of motor, impeller, the pump housing, and the pump housing is provided with water intake, compound diffusing tube, osculum, backflow road, collapsible tube.Before the pump startup, it is flat to be filled to water intake toward the pump housing, electric pump starts back impeller rotation, and water in the water intake and intake pipe part air are sucked together, becomes high pressure water through compound diffusing tube to acting, enter pump housing cavity through stator, gas is gentlier overflowed by osculum, and the part high-pressure water flow enters collapsible tube nozzle ejection in the chamber through the backflow road, again the intake pipe air is sucked, so circulation sucks pump working with water then fully until the intake pipe air has been arranged.Test shows that when the intake pipe height was 3 meters, self-priming time was about 1 minute; When the intake pipe height was 5 meters, self-priming time was about 3～4 minutes.
Owing to be subjected to that air influences in the water during pump startup, make the exhaust self-priming time longer, thereby influence effect.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of jet-type self-priming pump is provided.
Scheme of the present utility model is: fix a flow-stop valve at pump housing water intake, flow-stop valve valve body cylindrical is that step is cylindric, the step round platform is provided with four through holes, corresponding pump housing water intake cylindrical end face is provided with four corresponding tapped holes, four bolts pass the step round tube hole and stretch into tapped hole, implement the fixed installation of the flow-stop valve and the pump housing; Valve body central authorities are provided with two-way step through-hole, and left part step hole inwall is provided with internal thread, right part step hole and valve seat cover stationary fit socket; The right part step hole also is provided with the step ring concave table on the right side, and step ring concave table and pump housing water intake end face partly are clipped in the middle the seal ring of rubber seal valve block siamese part, are force-fitted state; The valve seat cover is tubular body, and the tubular element right side is the angular cut shape; Rubber seal valve block siamese part outer ring is the sealing endless loop, inner ring is the thin rounded flakes shape valve block that external diameter is slightly less than the endless loop internal diameter, be extension disjunctor sheet between thin rounded flakes upper end portion and the endless loop upper inside wall, disjunctor sheet thickness is half of endless loop, thin rounded flakes central authorities are enclosed with a circular steel disc, behind the endless loop location, thin rounded flakes left side and valve seat cover angular cut left side are the contact-type fit-state.
Advantage of the present utility model is: when pump was shut down, valve block was closed automatically; When starting once more, pump chamber need not exhaust and directly enters normal working, and efficient improves.Make idle work, energy saving simultaneously less.

Embodiment:
Structure of the present utility model is made up of motor, impeller, the pump housing, the pump housing is provided with water intake, compound diffusing tube, osculum, backflow road, collapsible tube, it is characterized in that: fix a flow-stop valve at pump housing water intake, flow-stop valve valve body (4) cylindrical is that step is cylindric, the step round platform is provided with four through holes, corresponding pump housing water intake cylindrical end face is provided with four corresponding tapped holes, and four bolts pass the step round tube hole and stretch into tapped hole, implement the fixed installation of the flow-stop valve and the pump housing; Valve body (4) central authorities are provided with two-way step through-hole, and left part step hole inwall is provided with internal thread, right part step hole and valve seat cover (5) stationary fit socket; The right part step hole also is provided with the step ring concave table on the right side, and step ring concave table and pump housing water intake end face partly are clipped in the middle the seal ring of rubber seal valve block (1) siamese part, are force-fitted state; Valve seat cover (5) is a tubular body, and the tubular element right side is the angular cut shape; Rubber seal valve block (1) siamese part outer ring is sealing endless loop (3), inner ring is the thin rounded flakes shape valve block (1) that external diameter is slightly less than endless loop (3) internal diameter, be extension disjunctor sheet between thin rounded flakes upper end portion and endless loop (3) upper inside wall, disjunctor sheet thickness is half of endless loop (3), thin rounded flakes central authorities are enclosed with a circular steel disc (2), behind endless loop (3) location, thin rounded flakes left side and valve seat cover (5) angular cut left side are the contact-type fit-state.
Be enclosed with circular steel disc (2) in the valve block (1) and be in order to strengthen valve block (1) rigidity, valve block (1) left side rubber body to be subjected under the hydraulic pressure state, can with the closely knit applying of valve seat cover (5) angular cut.Valve seat cover (5) angular cut setting is for valve block (1) can be by automatic sagging being attached on the angular cut of deadweight, and the existence of hydraulic pressure makes its applying tightr, can not leak gas.
Working principle is: after electric pump started, liquid was inhaled into impeller, and flow-stop valve is inwardly opened; After the intact shutdown of pump work, the outlet pipe return pressure closes flow-stop valve, makes the interior water of the pump housing and the hydropexis of intake pipe.When restarting water pump, need not exhaust, directly water inlet.
