Abstract
The utility model relates to a pair of suction type spray irrigation pump which belongs to agricultural water saving and irrigating machinery. The pair suction type spray irrigation pump comprises a water inlet elbow (5) whose upper part is connected with a small O-shaped rubber ring (8), a centripetal valve (9) and a hand pressing well (10) and lower part is connected with a big O-shaped rubber ring (3), a pressing plate (2) of 45 DEG and a water pipe (1). The side surface is connected with an assembling rubber plate valve (7) and a valve chamber (4), and the valve chamber (4) is connected with a spray irrigation pump body (6).
Description
Affiliated technical field:
The utility model relates to a kind of agricultural water-saving irrigation device.
Background technology:
Sprinkling irrigation pump is mainly used the agricultural water-saving irrigation aspect, because its water-saving performance is good, so utilize the exhibition of thing growth sprinkling irrigation pump very fast.But existing sprinkling irrigation pump water inlet and suction hose all are direct-connected plug-in types; therefore loading and unloading not only take merit but also gas leakage easily; have a strong impact on the complete machine performance; because the back-water valve (BWV) structure of hand well against current valve and water pump existing problems; all get back in the well and gone so shut down water in the pump of back and pipe water inside, again must be before the start from new diversion, unusual inconvenience; waste man-hour, just solved above-mentioned shortcoming as adopting counterpart odd test sprinkling irrigation pump.
Summary of the invention:
To load and unload inconvenient problem many in order to solve existing sprinkling irrigation water pump, and the utility model provides counterpart to take out sprinkling irrigation pump, not only easy to loading and unloading, air tight, not backwater, save time, laborsaving, can also improve mechanical efficiency.The technical scheme that its technical problem that solves the utility model adopts is:
The non-return valve of this pump hand down-hole face is to adopt O type cushion rubber and concave cone sealing on convex cone, so sealing property is very good.
Water inlet elbow below is with well casing or suction hose is vertical is connected, and the firm O type of employing 45 platen cushion rubber method makes the junction fastening air tight, can improve mechanical efficiency again.
The assembly adhesive plate valve is installed in water inlet elbow side, during start, the assembly adhesive plate valve enters valve chamber, do not influence the flow of water, during shutdown the assembly adhesive plate valve at the active force lower seal of backwater the elbow water return outlet, make in the pump and the water in the pipe can not be got back in the well, when starting shooting again, do not need the diversion more just can operate as normal, save time, laborsaving.The beneficial effects of the utility model are:
Novel structure, easy to loading and unloading, sturdy and durable, air tight, not backwater, do not need secondary diversion start, energy-conservation, save time, laborsaving.
Description of drawings:
Fig. 1 is the profile according to the counterpart odd test sprinkling irrigation pump device that the utility model proposes.
The specific embodiment:
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes:
Device comprises: above water inlet elbow (5) with little O type cushion rubber (8) entad valve (9) hand well (10) be connected.Below be connected with big O type cushion rubber (3) 45 platen (2) water pipe (1).The side is connected with assembly adhesive plate valve (7) valve chamber (4).Valve chamber is connected with the sprinkling irrigation pump housing (6).
Claims (1)
- Counterpart odd test sprinkling irrigation pump is characterized in that: above water inlet elbow (5) with little O type cushion rubber (8) entad valve (9) hand well (10) be connected, below be connected with big O type cushion rubber (3) 45 platen (2) water pipe (1), the side is connected with assembly adhesive plate valve (7) valve chamber (4), and valve chamber is connected with the sprinkling irrigation pump housing (6).
