Description
Technical field
The utility model relates to solenoid valve, exactly is the piston type pilot solenoid valve.
Background technique
Existing pilot solenoid valve cause solenoid valve normally not open and close, and multistage guide is because structure is loaded down with trivial details, manufacturing process is complicated because the pilot hole aperture is too small, the path is long, obstruction easily, cause the product cost height, be difficult for ensuring the quality of products, make the reliability decrease of solenoid valve, working life is shorter.In addition, because the O RunddichtringO that spool and valve seat primary seal mouth are adopted comes off therefore existing pilot solenoid valve multiselect profiled seal spare easily under the fluid force effect, lock with locking nut, cause the versatility of Sealing very poor, and complex process, the processing cost height.
The model utility content
At the deficiency that prior art exists, the utility model aims to provide a kind of piston type pilot solenoid valve.This solenoid valve is not only simple in structure, reliable performance, and the Sealing highly versatile, also prolongs several times the working life of product.
The technical solution adopted in the utility model is:
A kind of piston type pilot solenoid valve, comprise valve body, valve gap and electromagnet mechanism, the inside of described valve gap is provided with the piston valve core of sealed valve body primary valve, its center is provided with pilot hole, one end of valve rod is corresponding with pilot hole, the other end is connected with the moving iron core of electromagnet mechanism, and Spielpassung between spool and the valve gap inner chamber, the span of the difference of valve gap intracavity diameter and valve core diameter are 0.01mm～0.099mm.
The span of the difference of described stem diameter and pilot hole diameter is-2mm～+ 5mm.
Be connected by flexible way hinged or that hang between described valve rod and the moving iron core.
Described valve rod is made of macromolecular material and metal frame, the outer coated high molecular material of metal frame.
The outer macromolecular material thickness between the two that coats of the metal frame of described composite high-molecular valve rod is 0.01mm～15mm
The sealing part of described piston valve core and valve rod is equipped with embedded groove, and the O RunddichtringO is installed in it.
The ratio of described embedded groove Extreme breadth and minimum width is between 1: 0.99～1: 0.4.
The utility model is set in everywhere cooperation parameter in the valve within the reasonable range, and the structure and the Placement thereof of valve rod improved, electromagnetic valve structure is simplified, reliability promotes greatly, and life of product prolongs several times, the enhancing of Sealing versatility.
