The electromagnetic valve component can be made smaller and pressure on a passing object can be larger, so that both the energy and the cost can be saved.
Description
Technical field
The present invention relates to a kind of Lever 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 and closure member is mentioned valve open from valve seat; During outage, electromagnetic force disappears, and the spring handle closure member is pressed on the 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 the energising, electromagnetic force was directly upwards mentioned valve open to the little valve of guide and main valve closure member successively.When entrance and outlet reach when starting pressure reduction, after the 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: when zero pressure difference or vacuum, high pressure, also can move, 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, (need 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.
Summary of the invention
The purpose of this invention is to provide a kind of Lever 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.
Technological scheme of the present invention is: the Lever type one-way electromagnetic non return valve is comprised of electromagnetic valve component, solenoid valve dunnage, outer swing arm, upper valve body, lower valve body, interior swing arm, link arm, Oscillating bar, flap; Electromagnetic valve component places on the solenoid valve dunnage, and the solenoid valve dunnage places on the upper valve body, and upper valve body is connected with lower valve body; Outer swing arm is connected with electromagnetic valve component, swing arm in outer swing arm connects, and interior swing arm is connected with link arm, and link arm is connected with flap Yu Oscillating bar Lian Jie ， Oscillating bar, on the lower valve body fluid output and import is arranged.
The control principle of Lever type one-way electromagnetic non return valve of the present invention is: utilize solenoid valve energising adhesive, after utilizing lever principle that flap is promoted, open passage, so that water, vapour and oil can be without hindrance by valve body, the gas that passes through, liquid and oil base originally can the without hindrance unidirectional valve bodies that passes through.Solenoid valve is cutting out flap under the dual-pressure of gravity and water, vapour, oil after outage.The Lever type solenoid valve mainly is laborsaving, and the gas that passes through, liquid and oily flow are large, and the valve body aperture can be basic identical with caliber, is applicable on gas, liquid and the oil product of the large flow of demand.Electromagnetic valve component can be done a little bit smaller (other solenoid valve will just can meet the demands very greatly under the same traffic), and the object pressure that passes through can be more greatly, energy saving and cost.
