Abstract
The invention belongs to the field of aviation hydraulic technology, particularly relates to a method for improving anti-pollution capability of a pilot-operated type electromagnetic valve. By means of determining total area of the cross section of an oil inlet hole and an oil outlet hole, product non-operating states caused by blockings of the oil inlet hole or the oil outlet hole are avoided. With the method, optimization design is performed on products of the pilot-operated type electromagnetic valve, working reliability of the products is improved; and the maximum diameter of the oil inlet hole of the products can be determined (that is, the maximum diameter threshold of the oil inlet hole of the products can be determined by the method), so that the anti-pollution capability can be improved.
Description
Technical field
The invention belongs to the hydraulic air technical field, be specifically related to a kind of method that improves the guide electromagnetic valve contamination resistance, technology is mainly used in HYDRAULIC CONTROL SYSTEM valve series products such as aircraft, motor, by receiving the electric simulation signal, export corresponding flux signal, carry out the oil circuit control to hydraulic system.
Background technique
Traditional leading type hydraulic buttery valve all less than fixing pressure release ratio, all is to adopt the aperture oil-feed, the macropore pressure release, do not have fixing pressure release ratio to carry out product specification control, then cause product when design or do not reach the product optimized design, perhaps cause the product job insecurity.
Summary of the invention
The objective of the invention is: a kind of method that improves the guide electromagnetic valve contamination resistance is provided, can improves functional reliability and the contamination resistance of product.
Technological scheme of the present invention is:
A kind of method that improves leading type hydraulic buttery valve contamination resistance by determining the cross section gross area of oil-feed aperture and fuel-displaced aperture, is avoided causing product not worked owing to oil-feed aperture or fuel-displaced little hole plug.
Determine the step of oil-feed aperture and the fuel-displaced aperture cross section gross area: S
2/ S
1=N, wherein, S
2Be the cross section gross area of fuel-displaced aperture, S
1Be the cross section gross area of oil-feed aperture, N is any number between 0～4.5, is the effective coverage of product performance proper functioning within this numerical value.
Advantage of the present invention is:
The present invention will carry out optimized design to the product specification of leading type hydraulic buttery valve; Improve the functional reliability of product; Maximum diameter by the determining product oil-feed aperture maximum diameter critical value of product oil-feed aperture (that is: can determine by the present invention), and then can also improve the contamination resistance of product.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of method that improves leading type hydraulic buttery valve contamination resistance is characterized in that, by determining quantity and the cross section gross area of oil-feed aperture and fuel-displaced aperture, avoids owing to the little hole plug of oil-feed causes product not worked.
Determine the step of oil-feed aperture and the fuel-displaced aperture cross section gross area: S
2/ S
1=N, wherein, S
2Be the cross section gross area of fuel-displaced aperture, S
1Be the cross section gross area of oil-feed aperture, N is any number between 0～4.5, is the effective coverage of product performance proper functioning within this numerical value.
Because the application of leading type hydraulic buttery valve is more extensive, so environment of applications also has nothing in common with each other, and brought many restrictions with regard to the product specification of giving the leading type hydraulic buttery valve like this, and these restrictions mainly be pressure release than on.Be elaborated below by certain example.
Because the Environmental Conditions of certain aircraft is more abominable, mainly be contamination level of oil liquid higher (that is: fluid is dirtier), and this kind aircraft is transport airplane, therefore very big restriction is arranged again on weight, to guarantee also under the prerequisite of many restrictions that product must reliably working overcoming, therefore when product specification, will find, influence the position of product contamination resistance at the oil-feed aperture, guide electromagnetic valve oil-feed aperture in the past many be below diameter 1mm, when the oil-feed aperture surpassed a certain value, it is undesired that product will be worked.When the aperture is so little, also want antipollution to be difficult to, to select the aperture limiting value of a maximum when therefore designing, so just, can make product reach maximum contamination resistance, just can clearly select product maximum diameter of hole limiting value by the present invention, thereby reach optimization design of product.
Claims (2)
1. a method that improves the guide electromagnetic valve contamination resistance is characterized in that, by determining the cross section gross area of oil-feed aperture and fuel-displaced aperture, avoids owing to the little hole plug of oil-feed causes product not worked.
2. a kind of method that improves the guide electromagnetic valve contamination resistance according to claim 1 is characterized in that;
Determine the step of oil-feed aperture and the fuel-displaced aperture cross section gross area: S
2/ S
1=N, wherein, S
2Be the cross section gross area of fuel-displaced aperture, S
1Be the cross section gross area of oil-feed aperture, N is any number between 0～4.5, is the effective coverage of product performance proper functioning within this numerical value.
