The utility model has the advantages that: through set up the valve rod head at valve rod body top to the cooperation sets up prevents the maloperation device on the valve rod head, and prevents the maloperation device and can realize being connected and the disconnection with the valve rod head through the outer sleeve, thereby improves the security of using.
Drawings
Fig. 1 is a schematic view of the overall internal structure of the present invention;
in the figure: 1-external thread section, 2-valve rod body, 3-hand wheel, 4-valve rod head, 5-nut, 6-hand wheel connecting part, 7-buffer gasket, 8-hollow sleeve joint section, 9-matching connecting section and 10-outer sleeve.
Detailed Description
The invention is further described with reference to the accompanying drawings.
As shown in fig. 1, the valve rod for preventing misoperation comprises an external thread section 1, a valve rod body 2, a hand wheel 3, a valve rod head 4, a nut 5, a hand wheel connecting part 6, a buffer gasket 7, a hollow sleeve joint section 8, a matching connecting section 9 and an outer sleeve 10.
Prevent valve rod of maloperation, including valve rod body 2, the setting is at valve rod head 4 at 2 tops of valve rod body and prevents the maloperation device with valve rod head 4 matched with, be equipped with external screw thread section 1 on the valve rod body 2, prevent that maloperation device includes outer sleeve 10, the hand wheel connecting portion 6 of setting on outer sleeve 10 and the hand wheel 3 of setting on hand wheel connecting portion 6, the inside cooperation linkage segment 9 and the cavity of being equipped with of outer sleeve 10 cup joint section 8, cooperation linkage segment 9 can cooperate with valve rod head 4, the cavity cup joints section 8 and can overlap and establish in the valve rod head 4 outside.
In this embodiment, the hand wheel connecting portion 6 is an external screw head, and is integrated with the outer sleeve 10, and the hand wheel 3 is fixed on the hand wheel connecting portion 6 through the nut 5.
In this embodiment, a cushion pad 7 is disposed at the top of the hollow sleeve section 8 in the outer sleeve 10 for protecting the valve stem head 4.
The utility model discloses when the valve rod uses, with outer sleeve 10 upwards draw to with valve rod head 4 phase-match (cooperation linkage segment 9 is connected with valve rod head 4), then can twist valve rod body 2 through hand wheel 3 and move, when the valve rod does not use, with outer sleeve 10 downwards push to break away from with valve rod head 4 (cooperation linkage segment 9 drops with valve rod head 4), 8 covers of cavity cup joint section of outer sleeve 10 are established at valve rod head 4 this moment, rotate hand wheel 3 and can not twist the valve rod body and move, the effectual security of guaranteeing the use, prevent the emergence of maloperation.
