Embodiment four
Referring to Fig. 3, be provided with two stuffing box glands in the present embodiment between valve rod and the valve body, along being fixed in the valve rod periphery, the stuffing box gland outer is fixed in body cavity wall periphery, and spacing with 9 pairs of stuffing box glands of limited ring in the stuffing box gland.The cavity that constitutes between the first stuffing box gland 8-1 and the second stuffing box gland 8-2 is an input cavity, is communicated with input interface 11; The second stuffing box gland 8-2 and valve body left side inner chamber constitute output cavity, lead to output interface 3; The first stuffing box gland 8-1 and valve body right side inner chamber constitute counter balance pocket, and counter balance pocket links to each other with output cavity through balance bypass tube 4, and balance bypass tube 4 links to each other with output cavity through output interface 3 in this example.Valve rod introduction hole 7 is circular, is arranged in around the valve rod stage casing between interior edge of first stuffing box gland and the interior edge of second stuffing box gland; Valve hole 10 also is circular, is arranged in second stuffing box gland along the left side; Go up for upper and lower section of valve rod and arrange balance pod apertures 2.Two cover electromagnetism open-and-close mechanisms are arranged at the two ends of valve rod, and it comprises electromagnetic coil 13 and iron core 12, and iron core 12 is fixed in the valve rod termination respectively.This routine switching principle is identical with embodiment two.
Arrange identical stuffing box gland on the cylindrical body valve rod of the present invention, the formed identical stuffing box gland gap of identical limited ring, its input cavity internal pressure changes in any case, and wherein the pressure with respect to valve rod is balance all the time.When stem movement, two stuffing box glands are done the action that stretches respectively, because two stuffing box glands on same valve rod, its stretching travel equates, so the volume no change in the input cavity.And the Fluid Volume that holds in the spacing formed micro-gap of limited ring in the stuffing box gland seldom.Form by the electromagnetic force adhesive in the stuffing box gland gap of the stem movement that is exceedingly fast and movement therewith and form slight pressure wave; The transmission of this pressure wave; Can present non-linear increase along with the enhancing of hydrodynamic pressure, the NPW that stuffing box gland produced that can be upheld fast by another is simultaneously alleviated, therefore; Pressure wave in the high pressure is spontaneous and go out, and can ignore.So when the valve rod move left and right, its resistance of exerting pressure constant all the time (being mainly stuffing box gland varicose power) does not receive the influence of valve interior fluid pressure.No matter hydrodynamic pressure increases to much, valve rod is exerted pressure constant all the time, and this has just created very advantageous conditions for the stable operation of solenoid valve electromagnetic force; The hydrodynamic pressure that solenoid valve is controlled, no matter be low pressure, also pipe pressure does not have much; Can both be relieved, arbitrarily control restfully.In addition because stuffing box gland covers the coverage rate external and internal pressure balance all the time on the valve hole, so valve does not receive the influence of hydrodynamic pressure all the time.Simultaneously, because the limited ring that is provided with can make that two stuffing box glands will be minimum from the pressurized clearance plane restriction of huge hydrodynamic pressure in the valve body; If again stuffing box gland technology is made into the lacing wire strengthening sleeve; Promptly can be applicable to ultrahigh pressure, form ultrahigh pressure direct-acting type universaling electromagnetic valve, use of far-reaching significance.In addition, because this electromagnetic valve is to open with outside rolling of valve rod, do not cover the sealing effect with close valve orifice once more so do not influence valve pocket from the solid granulates that flows out in the valve rod yet.So the combining of this valve and electromagnetism adhesive device can solve nearly all critical defect of present existing technology and deficiency.
The applicable different environment pressure of the present invention, the against vacuum external environmemt, the low pressure external environmemt, high pressure external environmemt and ultrahigh pressure external environmemt can both be suitable for.The hydrodynamic pressure state that this universal solenoid valve internal switch is controlled both can be a low-pressure state, also can stably work in high pressure conditions, even ultrahigh pressure state (for example using as the deep-sea solenoid valve in the seabed in the seafari).Can also be modulating valve according to the size of current regulating valve flow of electromagnetic force, also be solenoid valve.When adopting two electromagnetism open-and-close mechanism,, just can realize opening or closing valve as long as be taken up in order of priority two DC pulses of input for the two ends electromagnetic coil, thus effective saving power.
