Abstract

The utility model relates to a hand-operated pressure water machine which is provided with a double working journey and a one-way valve with reliable performance. The lower cylinder of a pressure water cylinder rubber piston is provided with a water inlet pipe and a water outlet pipe. The water inlet pipe port is provided with the one-way valve, and the water outlet pipe is connected with the one-way valve of an air cylinder. The upper cylinder of the piston is provided with a return pipe which is connected with another one-way valve of the air cylinder which is provided with a water outlet pipe mouth. A piston rod and a pressure water rod are hinged, and the pressure water rod and a support post are hinged. The utility model has the advantages of deep suction lift, high lift, big water output, easy use and reliability and can be widely used for factories, countryside and families.

Description

Hand-operated variable-pitch vacuum water pump

The utility model is relevant with hand water pump, and especially to make stroke multipurpose hand pump relevant with duplex.

Traditional hand water pump, used valve is the steel ball valve, usually owing to get rusty and akinesia, water pump can not be worked in the use.Working stroke all is an one way, and water-outlet quantity is little.Traditional hand water pump is fixing inconvenient, requires great effort during use, and efficient is low.

The purpose of this utility model provides a kind of simple in structure, and is with low cost, easy to use, and water-outlet quantity is big, the manual bending moment type vacuum of the high efficiency that lift is high squeezer.

In the setting-out cylinder of the present utility model rubber piston is arranged.The cylinder body of piston bottom has intake pipe and outlet pipe.Water inlet pipe mouth has one-way valve.Outlet pipe is connected with the one-way valve of air cylinder.Piston top cylinder body has return pipe, and return pipe is connected with another one-way valve of air cylinder.Air cylinder has outlet pipe to chew.Piston rod and setting-out bar are hinged, and setting-out bar and pillar are hinged.

One-way valve of the present utility model can be made by garden shape sheet rubber, and sheet rubber has Nei Yuan to link to each other with outer garden, and interior garden diameter is greater than the water inlet caliber.Sheet rubber is positioned on the rubber setting-out packing ring, is tightened by jump ring.Intake pipe is fixed on setting-out cylinder bottom portion, the mouth of pipe is by garden sealing in the sheet rubber, but the one-way valve double leaf one-way valve of air cylinder, make by garden shape sheet rubber, the inboard two garden shape valve blocks that protrusion is arranged of the outer garden of sheet rubber ring, the diameter of valve block is greater than the diameter of connected return pipe and outlet pipe, return pipe and outlet pipe are fixed on the air cylinder base plate, the mouth of pipe is sealed by valve block, and the double leaf one-way valve is positioned on the packing ring, by air cylinder flange circle and bolton sealing.

But the utility model organic block and fixing device.

During the utility model work, the setting-out bar plays leverage.When piston moved upward, the one-way valve that water is washed the setting-out cylinder open by intake pipe entered packing space in the cylinder, at this moment the closed check valve of air cylinder.When piston moved downward, water was washed one-way valve open by outlet pipe and is entered air cylinder, and the air in the air cylinder is compressed, and pressurized air is chewed water to extrude from outlet pipe and formed high pressure water.This moment, a part of water entered setting-out cylinder piston top by piston rubber edge, when piston moves upward once more, the water on piston top flows out from return pipe, the one-way valve of washing the air cylinder bottom open enters air cylinder, air in the compressed air cylinder, high-pressure air are chewed water to extrude from outlet pipe and are formed high pressure water.So go round and begin again, outlet pipe is chewed constantly has high pressure water to flow out.The utility model is in light weight, volume is little, inhales Cheng Shen, the lift height, and water-outlet quantity is big, and is easy to use, reliably laborsaving.Inhale journey and can reach 20 meters, 35 meters of lifts, 1.8 tons/hour of flows.Diversion need be do not added during use, and use can be moved at any time.But except that setting-out, also can extract liquid dung and irrigate crops, add upper nozzle sprinkling irrigation nursery.Can be widely used in factory, rural area, family.
