Description
Affiliated technical field
The utility model relates to a kind of particularly high-temperature solenoid valve of high-temperature high-pressure medium of various media that is applicable to.
Background technique
Existing high-temperature solenoid valve is made up of main valve body, auxiliary valve body, valve rod, pull bar and moving iron core and static iron core etc., the entrance point of main valve body inner chamber and valve, outlet end constitute the main valve passage, valve cup and guide sleeve are positioned at the main valve seat top of main valve body, the guide sleeve outer side surface is connected with main valve body, the valve cup inserts in the guide sleeve, valve cup end face is coaxial with the main valve seat through hole, bigger than main valve seat outer rim, exceed the main valve seat peripheral edge portion on the side of valve cup and/or the end face and have damping hole, the pull bar upper end connects moving iron core, and the lower end is connected with valve rod with fork by pivoted arm, rotating shaft.During the solenoid valve energising, moving iron core is under the effect of electromagnetic force, overcome spring force and move up together with pull bar, pull bar drives the rotating shaft rotation by pivoted arm, and then moves on the drive valve rod, secondary valve passage in the open auxiliary valve body, medium in the valve cup inner chamber flows to outlet end by secondary valve passage, and the pressure medium of valve cup inner chamber descends, and finally causes the valve cup to rise, open the main valve passage, solenoid valve is open-minded; During the solenoid valve outage, pull bar is left behind by spring, pull bar drives the fork counterrotating by pivoted arm, rotating shaft, and then drive valve rod and move down, make the Sealing of valve rod lower end seal secondary valve passage, at this moment medium continues to flow into valve cup inner chamber by damping hole, cause the pressure medium of valve cup inner chamber constantly to increase, finally force the valve cup to move down, seal the main valve passage, closed electromagnetic valve.The major defect of this solenoid valve is: the one, and the valve cup expands limitedly under the high temperature, has reduced the gap between valve cup and the guide sleeve, harms the valve cup and moves up and down, and makes electromagnetic valve switch ineffective; The 2nd, the pull bar displacement distance that opens solenoid valve needs is longer, and the distance between moving iron core and the static iron core is bigger, and interaction force is little, when pressure medium is higher, and the opens solenoid valve difficulty; The 3rd, under solenoid valve was opened state, the valve cup was by jam, and the distance between moving iron core and the static iron core is minimum, and the interaction force maximum twists off rotating shaft easily, makes solenoid valve malfunctioning; The 4th, this electromagnetic valve structure complexity, cost of production height.
The model utility content
For overcoming the above-mentioned defective of prior art, the utility model proposes a kind of high-temperature solenoid valve, it is under any pressure medium and temperature, all but the maintaining valve cup moves flexibly, the phenomenon that can not start under the high pressure can not take place, do not establish rotating shaft in the solenoid valve, do not exist rotating shaft to damage problem, solenoid valve is simple in structure simultaneously, and cost of production is low.
The technical solution of the utility model is: high-temperature solenoid valve comprises main valve body, guide sleeve, the valve cup, auxiliary valve body, pull bar, spring and moving iron core and static iron core, the main valve body inner chamber is arranged in the main valve body, the main valve body lumen openings is in the entrance point and the outlet end of valve, be provided with main valve seat in the main valve body, through hole on the main valve seat is communicated with entrance point and outlet end by the main valve body inner chamber, form the main valve passage of medium, guide sleeve is positioned at the main valve seat top, the valve cup inserts in the guide sleeve, its end face is coaxial with the main valve seat through hole, bigger than main valve seat outer rim, its side and/or end face exceed the main valve seat peripheral edge portion and have damping hole, the auxiliary valve body inner chamber is arranged in the auxiliary valve body, the auxiliary valve body lumen openings is in secondary valve entrance point and secondary valve outlet port end, be provided with auxiliary-seat in the auxiliary valve body, the auxiliary-seat through hole is communicated with secondary valve entrance point and secondary valve outlet port end by the auxiliary valve body inner chamber, form secondary valve passage, the upper end of pull bar connects moving iron core, moving iron core and static iron core are formed Electrical heads, be positioned at the solenoid valve top, spring one end is fixed, the other end is fastened on the pull bar, the utility model difference from prior art is, one fixed gap is arranged between guide sleeve side and the main valve body, the lower end surface is connected with main valve body, and auxiliary valve body is positioned at upper part of the main valve body, is connected with main valve body, secondary valve entrance point is communicated with valve cup inner chamber, secondary valve outlet port end is communicated with the outlet end of valve, and the pull bar lower end has secondary valve seal, is positioned at the auxiliary-seat top.When solenoid valve is switched on, moving iron core is under the effect of static iron core, move up, drive on the pull bar and move, the Sealing of pull bar lower end leaves auxiliary-seat, secondary valve passage is open-minded, medium in the valve cup inner chamber flows out through secondary valve passage, the inner chamber pressure medium drops to gradually with the outlet end pressure medium and equates, because valve cup end face exceeds the pressure medium that pressure medium that the main valve seat peripheral edge portion is subjected to is substantially equal to entrance point, this pressure is greater than the pressure medium of outlet end, the valve cup is suffered to upward pressure greater than suffered downward pressure, the valve cup is moved up, open the main valve body road, solenoid valve is open-minded; During the solenoid valve outage, active force between moving iron core and the static iron core disappears, pull bar moves down under the effect of spring, the secondary valve seal of pull bar lower end is sealed the auxiliary-seat through hole, cut off secondary valve passage, at this moment the medium of entrance point can continue to flow into valve cup inner chamber by the damping hole on the valve cup, the pressure medium of valve cup inner chamber is constantly raise, when the suffered downward pressure of valve cup inner chamber during greater than suffered the upwarding pressure of valve cup end face, the valve cup moves down, seal the main valve seat through hole, cut off the main valve body road, closed electromagnetic valve.
The beneficial effects of the utility model are: because the guide sleeve side is with leaving a fixed gap between the main valve body, under high medium temperature, allow guide sleeve and the radial expansion of valve cup, the gap between guide sleeve and the valve cup is not subjected to temperatures involved, thereby has kept valve cup flexible motion at high temperature; Because the pull bar displacement distance that opens solenoid valve needs is the distance that secondary valve seal leaves auxiliary-seat, the existing needed pull bar displacement distance of solenoid valve is little than opening, therefore can shorten the distance between moving iron core and the static iron core, increase the active force of static iron core to moving iron core, the pulling force of selecting suitable pull bar diameter that the pulling pull bar is needed is not simultaneously influenced by pressure medium, has eliminated the problem that solenoid valve is difficult to open under the high-pressure medium; Owing to do not establish rotating shaft, it is malfunctioning to have avoided rotating shaft to damage the solenoid valve that produces; In addition, this technological scheme has also been simplified the structure of solenoid valve, has made things convenient for installation, helps reducing production costs, and has also beautified appearance and modeling.
