Abstract
The utility model relates to an indicating device for the switch stroke of a magnetic valve. A hand wheel of the magnetic valve is fixedly connected with a cover casing, and a screw sleeve is arranged in the cover casing and is matched and connected with a screw rod which is arranged on the upper end of a fixing screw bolt of a distance sleeve of the magnetic valve by an inner screw thread in an extending mode. The side wall of the cover casing is provided with a groove hole on a longitudinal direction, and the screw sleeve is fixedly connected with an indicating pin rod in the groove hole. When the hand wheel is rotated, the cover casing follows the hand wheel to rotate, and the screw sleeve is driven by the indicating pin rod to rotate so that the screw sleeve moves up and down and drives the indicating pin rod to moves up and down, and the indication of the opening condition of the valve is completed. The utility model overcomes the defect that the switch stroke of a magnetic valve is not indicated and not marked.
Description
Technical field
The utility model relates to valving, particularly the switching path indicating device of non-leakage magnetic valve.
Background technique
Magnetic valves is a kind of magnetic drives leakage-free valve, be mainly used in the pipeline of poisonous, harmful, aggressive medium and use, existing its valve rod dirivig member of Magnetic valves is all in the separation sleeve of valve body, the outside has only one to be connected the handwheel that drives its rotation on the outer magnetic matrix, so can't see the switching and the unlatching situation of valve in using from the outside, this makes it produce inconvenience in using, and uses and is subjected to certain limitation.
The model utility content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of Magnetic valves switching path indicating device is provided, and does not have the shortcoming of indicateing arm will, easy to use and control valve to overcome the Magnetic valves switching path.
The technical solution of the utility model is, fixedly connectedly in the upper end, middle part of the handwheel 1 of Magnetic valves be provided with a case 4, in case 4, be provided with a swivel nut 51, swivel nut 51 extends the screw rod 52 that is provided with by the upper end of the fixing bolt 21 of the separation sleeve 2 of internal thread and Magnetic valves and is connected, on warding off vertically, case 4 sides offer slotted eye 41, pass slotted eye 41 and be fixedly connected with pin rod 6, i.e. an indicating arm with swivel nut 51.
When the utility model rotates when handwheel 1, case 4 rotates with handwheel 1, indication pin rod 6 on the case 4 in the slotted eye 41 drives swivel nut 51 and rotates, the internal thread of swivel nut 51 cooperates with screw rod 52, make swivel nut 51 do/descend to move, on the swivel nut 51 drive indication pin rods 6/and move down, finish the valve opening situation is indicated.The utility model can directly be seen the switching and the unlatching situation of valve from the outside.

Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The utility model is fixedly connected in upper end, the middle part of the handwheel 1 of Magnetic valves to be provided with a case 4, in case 4, be provided with a swivel nut 51, swivel nut 51 extends the screw rod 52 that is provided with by the upper end of the fixing bolt 21 of the separation sleeve 2 of internal thread and Magnetic valves and is connected, can certainly be screw rod 52 to be set specially be connected on the fixed plate 20 of separation sleeve 2 with swivel nut 51, on case 4 sides are warded off vertically, offer slotted eye 41, in slotted eye 41, fixedly connected indication pin rod 6 with swivel nut 51.
Shown in accompanying drawing embodiment, the utility model offers groove draw-in groove 54 at the sidepiece of swivel nut 51, in draw-in groove 54, be provided with ring cotter pin formula wearing piece 53, corresponding draw-in groove 54 is provided with the collar 55 on the outer shroud of swivel nut 51, the screw screw-thread fit of offering on indication pin rod 6 and the collar 55 is connected, and the front end item of indication pin rod 6 is pressed wearing piece 53, and the wearing piece 53 and draw-in groove 54 inboards of swivel nut 51 are adjacent to.Its working principle as hereinbefore, just swivel nut 51 rotates with case 4 by indication pin rod 6 under the friction effect of wearing piece 53, swivel nut 51 drives on the indication pin rod 6 again/mobile down.Its advantage one is that installation is simple and convenient, when rotating to, valve opens or closes fully when closing the position, indication pin rod 6 is subjected to that bottom stops that wearing piece 53 skids with swivel nut 51 on the slotted eye 41 that case 4 sides offer on warding off vertically, makes indication pin rod 6 can locate the initial position of corresponding valve switch automatically; The 2nd, when arriving, changeover valve opens or closes fully when closing the position in the work, owing to firmly be rotated further handwheel, wearing piece 53 and swivel nut 51 are skidded, ensure to make indication pin rod 6 can not continue mobile stress deformation.
