The direct-type unidirectional non-return electromagnetic valve has the advantages that the flow of passing gases, liquids and oil is great; the pore sizes of the valve bodies can be basically equal to the pipe diameter; the flow of the gases, liquids and oil can basically passes through the valve bodies unidirectionally without barriers; the direct-type unidirectional non-return electromagnetic valve is suitable for gas, liquid and oil products with requirement of high flow; also the electromagnetic valve can be manufactured to be small, and can prevent the back flow of the gases, the liquids and the oil by utilizing a unidirectional non-return principle; and power can be very small, so that energy sources and cost are saved.
Description
Technical field
The utility model relates to a kind of direct-type one-way electromagnetic non return valve.
Background technique
Existing solenoid valve is divided into following several:
1, direct action solenoid valve principle: during energising, electromagnetic coil produces electromagnetic force mentions closure member from valve seat, valve open; During outage, electromagnetic force disappears, and the spring handle closure member is pressed on valve seat, valve closing.Characteristics are: can work when vacuum, negative pressure, zero-pressure, but latus rectum generally is no more than 25mm.
2, distribution direct action solenoid valve principle: it is a kind of straight moving and principle that leading type combines, and when entrance and outlet did not have pressure reduction, after energising, electromagnetic force was directly upwards mentioned the little valve of guide and main valve closure member successively, valve open.When entrance and outlet reach when starting pressure reduction, after energising, the little valve of electromagnetic force guide, main valve cavity of resorption pressure rise, upper cavity pressure descends, thereby utilizes pressure reduction that main valve is upwards pushed open; During outage, pilot valve utilizes spring force or pressure medium to promote closure member, moves down, and makes valve closing.Be characterized in: also can move when zero pressure difference or vacuum, high pressure, but power is larger, requires and level to install.
3, guide electromagnetic valve principle
:During energising, electromagnetic force is opened pilot hole, and upper chamber's pressure descends rapidly, forms low high pressure reduction around closure member, and hydrodynamic pressure promotes closure member and moves up, valve open; During outage, spring force cuts out pilot hole, and inlet pressure bends down high pressure reduction by the formation around closing valve member of the rapid chamber of by-pass hole, and hydrodynamic pressure promotes closure member and moves down, throttle down.Be characterized in: the hydrodynamic pressure range limit is higher, (needing customization) can be installed arbitrarily but must satisfy the fluid pressure difference condition.
The throughput of the water of above-mentioned existing solenoid valve, vapour and oil is very little, can not satisfy the demand of special industry, and particularly on micro-cultivator electronic safety protection device, existing solenoid valve all can not satisfy micro-cultivator electronic safety protection device to be used.If make existing solenoid valve, it is very large that solenoid valve will be done, and cost of production is high, and peasant household can not accept certainly.
Summary of the invention
The purpose of this utility model is to provide a kind of direct-type one-way electromagnetic non return valve that solenoid valve and one way stop peturn valve are united two into one; the gas that passes through, liquid and oily flow can without hindrancely pass through valve body substantially; the gas that passes through, liquid and oily flow are large; be applicable to also can satisfy the requirement of micro-cultivator electronic safety protection device on gas, liquid and the oil product of the large flow of demand.
The technical solution of the utility model is: the direct-type one-way electromagnetic non return valve is by electromagnetic valve component, upper valve body, lower valve body, link arm, the flap assembly forms, and electromagnetic valve component is placed on upper valve body, electromagnetic valve component is connected with the flap assembly by link arm, the flap assembly is placed in lower valve body, on lower valve body, fluid output and fluid inlet is arranged, and upper valve body and lower valve body are bolted.
The flap assembly is comprised of rocking bar, cotter pin I, slotted nut and flap, and flap links together by slotted nut and rocking bar, and by cotter pin I locking slotted nut.
Control principle is: after utilizing solenoid valve energising adhesive that flap is promoted, open passage, make water, vapour and the oil can be without hindrance by valve body, solenoid valve cutting out flap under the dual-pressure of gravity and water, vapour, oil after outage.But this solenoid valve is used on the control break-make of the large water of the not high traffic requirement of pressure, vapour, oil.
The utility model is to utilize the throughput of one way stop peturn valve large, and the swift characteristics of solenoid valve, and they are combined, and can make simultaneously the gas, liquid and the oil base that pass through originally can the without hindrance unidirectional valve body that passes through.
Direct-type one-way electromagnetic non return valve advantage of the present utility model is that the gas, liquid and the oily flow that pass through are large, and the valve body aperture can be basic identical with caliber, and the gas that passes through, liquid and oily flow substantially can the without hindrance unidirectional valve bodies that passes through.Be applicable on gas, liquid and the oil product of the large flow of demand.And it is very little that solenoid valve can be done, and also can stop the backflow (under same traffic, other solenoid valve will just can meet the demands very greatly) of gas, liquid and oil with the principle of one-way non-return, and it is very little that power just can be done, thus energy saving and cost.
