Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in figure 1, being provided with magnetic valve 101 outside a kind of gas spray valve of hydraulic-driven, valve body 100, pass through electromagnetism
The break-make control hydraulic oil inlet-outlet valve body inner chamber of valve 101, moves valve element 103, and then open or close injection valve.
Valve pocket 104 is provided with valve body 100, in order that valve pocket is not rotated, holding screw 109 is provided with valve body 100.
The valve rod of valve element 103 is slidably matched with valve pocket 104, and valve rod has what is stretched out respectively from the two ends for stretching out valve pocket 104
First extension and the second extension.First extension of valve rod is connected with magnet 105, valve body 100 fixed by magnetic receiver
There is magnetic field sensor 102, magnetic field sensor 102 is corresponding with the position of magnet 105, for detecting the change in magnetic field, so as to perceive
The stroke of valve element 103, signal transmssion line 113 will detect that signal reaches electric-control system.Magnet 105 is magnet ring or magnetic
The other shapes such as iron block.In the magnetic receiver, magnetic receiver body 107 is threadedly coupled with the first extension of valve rod and (can also used
The other manners such as interference are connected), magnet 105 is locked on magnetic receiver body 107 by nut 106, by the locking of nut 106 only
It is a kind of form that magnet 105 is fixed, can also be fixed by forms such as bondings.
In reality, along the circumferential direction there is magnetic contrast in magnet, if valve element 103 rotates in moving process, that
Magnet 105 can also be rotated, so since, the difference of magnet in itself will reflect in the detection signal of magnetic field sensor, from
And judge to bring error to the stroke of valve element 105, and then influence measurement accuracy.
In order to eliminate due to the detection error that the magnetic contrast that magnet is along the circumferential direction present is brought to magnetic field sensor, carry
In high measurement accuracy, the present embodiment, slide guide device is provided between valve rod and valve pocket 104.Slide guide device causes
Valve element 103 will not rotate in movement, specifically include following structure：
As shown in Figures 2 and 3, jagged 1031 are opened up valve rod is cylindrical, breach 1031 has guide surface, guide surface
It is parallel with the axially extending direction of valve rod.Moreover, valve pocket 104, which is offered, is provided with rolling post 110 in through hole, through hole, post is rolled
110 fit with the guide surface of valve rod breach 1031.Roller ball 112,112 points of roller ball are provided with the through hole of valve pocket 104
It is placed in the two ends for rolling post 110.In order to close the through hole of valve pocket 104, closure ring is provided between valve pocket 104 and valve body 100
111。
Slide guide device is not limited to said structure, for example, be connected valve rod with the feather key of valve pocket 104, and can also play makes valve
The effect that core 103 will not rotate in movement, but be sliding friction between the prismatic pair of the structure, resistance can be larger.
As shown in figure 1, the second extension of the valve rod of valve element 103 is arranged with back-moving spring 108, back-moving spring 108 is clamped
Between closure ring 111 and the end of the extension of valve rod second, now, the effect for the spring washer that closure ring 111 is also acted.
