Abstract

The utility model relates to a light and small centrifugal pump, comprising a pump body, a check valve and a hand-operated guiding valve. The utility model is characterized in that a water guiding valve is the hand-operated guiding valve which is communicated with and arranged at the upper part of the inner side of the water-sucking inlet of the pump body. The inner of the valve body is provided with a water chamber and an air chamber; a valve plug is arranged on a supporting frame through a lifting bar and a pressing handle; the check valve is arranged in the inner of the water outlet of the pump body. When the commercial power is switched on, the utility model can use the commercial power as power; when the commercial power is not switched on, a diesel engine or a miniature tractor can be used as the power; when needed, the water can also be pumped out through moving the pressing handle up and down manually. The utility model has the advantages of reliable work, labor saving, favorable performance, compact structure, beautiful and compact appearance, low cost and convenient use and maintenance.

Description

A kind of small-sized centrifugal pump

The utility model relates to a kind of pump, the small-sized centrifugal pump that use in particularly a kind of suitable rural area.It includes the pump housing, one-way valve and manually draws valve.

The one-way valve of existing centrifugal pump is arranged on the bottom of intake pipe, diversion valve is installed in the water outlet of the pump housing, water injection rate was many when this traditional centrifugal pump started, effort is big, can only be with civil power or the bigger diesel engine source that is used as power, can not use very not inconvenient in the rural area of not having electricity with the microtractor source that is used as power.

It is little that the purpose of this utility model provides a kind of tripping force, can use the be used as power small-sized centrifugal pump in source of minitype motivation.

Task of the present utility model is finished as follows, it is the improvement to existing centrifugal pump, it includes the pump housing, one-way valve and diversion valve, it is characterized in that: diversion valve is manually to draw valve, be communicated with inboard top, the water sucking mouth that is installed in the pump housing, the inner chamber of valve body has two steps, an one-way valve is housed on getting out of a predicament or an embarrassing situation, a valve plug is housed on topping bar, above body cavity is divided into is hydroecium, be air chamber below, the valve plug center upwards is fixed with shadoof, and shadoof stretches out valve gap and connects with bearing pin with pressure handle, pressure handle outwards bend 90 the degree be fixed on valve outer wall on bearing support connect by bearing pin, an one-way valve is installed in the water outlet of the pump housing, and the water outlet center line is curved to become 60～80 to spend angles with horizontal line.

The utlity model has following good effect: it has solved all bootable difficult problem of there is electric power or not, when being arranged, use civil power civil power to be used as power, can be used as power with diesel engine or microtractor during no civil power, can also water be extracted out with the pressure handle that manually moves up and down in case of necessity.The product reliable operation, laborsaving, performance is good, compact structure, profile is small and exquisite attractive in appearance, and price is low, convenient maintenance.

Fig. 1 is a structural representation of the present utility model.

Describe embodiment in detail below with reference to accompanying drawing.

As shown in the figure, the utility model is the improvement to existing centrifugal pump, the water sucking mouth 15 of the pump housing 1 is suitably increased, and install one in the connection of inboard top and manually draw valve, manually draw valve insertion two steps are arranged, an one-way valve 14 is housed on getting out of a predicament or an embarrassing situation, a valve plug 13 is housed on topping bar, it is hydroecium that body cavity is divided into, under be air chamber, valve plug 13 centers upwards fix with shadoof 11, and shadoof 11 protrudes upward valve gap 7 and connects with pressure handle 8 usefulness bearing pins 6, pressure handle 8 bending 90 degree above valve body 12 sides be fixed on valve outer wall on bearing support 11 usefulness bearing pins 9 connect.Water outlet 2 ends at the pump housing 1 are fixed the water outlet 3 that one-way valve 4 is equipped with in a bottom with bolt and nut 5, and water outlet 3 center lines are curved to become 60～80 degree angles with horizontal line, and 75 best results when spending can reduce the resistance of water outlet so in a large number, cut down the consumption of energy.

Add a spot of water as long as will manually draw the hydroecium and water outlet 3 internal check valves 4 tops of valve earlier during work, with hand pressure handle 8 is moved up and down for several times, be fulcrum with the bearing pin on the bearing support 10 9 when pressure handle 8 moves up and down, the other end drives shadoof 11, interlock valve plug 13 oppositely moves up and down in hydroecium, owing in the water outlet 3 of the pump housing 1 one-way valve 4 is arranged, can only give vent to anger during valve plug 13 motion can not air inlet, make the air in the pump housing 1 and the suction sleeve constantly be drawn out of and form negative pressure, water is promptly through suction sleeve, the pump housing 1, one-way valve 4, water outlet 3 is drawn out of, connect power source again (as motor this moment, diesel engine, microtractor) make centrifugal pump work, water is promptly constantly released.Because water outlet 3 is designed to 75 degree arcs, it is little to go out water resistance, less energy consumption.Even do not having to depend merely on the motion that manpower does not stop pressure handle 8 under the situation of power source, also can water be extracted out through water outlet 3 from underground as water pump.So being particularly suitable for the rural area of short of electricity, uses the utility model.

Claims (2)

1, a kind of small-sized centrifugal pump, it includes the pump housing, one-way valve and manually draw valve, it is characterized in that: diversion valve is manually to draw valve, be communicated with the 15 inboard tops, water sucking mouth that are installed in the pump housing 1, the inner chamber of valve body 12 has two steps, an one-way valve 14 is housed on getting out of a predicament or an embarrassing situation, a valve plug 13 is housed on topping bar, above valve body 12 inner chambers are divided into is hydroecium, be air chamber below, valve plug 13 centers upwards are fixed with shadoof 11, and shadoof 11 stretches out valve gap 7 and connects with pressure handle 8 usefulness bearing pins 6, pressure handle 8 outwards bending 90 degree connects by bearing pin 9 with bearing support 10 on being fixed on valve body 12 outer walls, and an one-way valve 4 is installed in the water outlet 3 of the pump housing 1.
