Description
Technical Field
The utility model relates to a valve on-off state indicates technical field, concretely relates to valve state sign.
Background
The valve on-off state indicator used in the current industrial and mining places is of a suspension type and a magnetic adsorption turnover type, wherein the magnetic adsorption turnover type is a plastic indicator with two plastic surfaces marked with an opening character and a closing character, and an embedded magnet block can be directly adsorbed on any part of a valve body.
For example, the device status indicator disclosed in chinese utility model patent No. CN200979017Y includes a housing and a magnet therein, the housing is in the shape of an ellipse or a rectangle, labels with characters printed on the surfaces are attached to the front and back surfaces of the housing, and the characters on the labels are on, off, or on or off for use. During the use, the magnetism that utilizes magnet with the sign paste the valve below can, because the magnet package in the casing, not with equipment direct contact, do not have the harm to valve and pipeline equipment. The sign that can directly overturn after the valve changes the state changes the content of instruction, convenient and practical.
However, after the state of the valve is changed, the indicator must be taken off from the valve, a face is turned over and then pasted again, the indicator needs to be taken off and then pasted every time, the operation is troublesome, the indicator pasted again often changes the position of adsorption and fixation, the phenomena of askew hanging, oblique hanging, mistaken hanging and the like often appear, and the whole visual effect is damaged.
Suspension type sign among the prior art is hung on the valve hand wheel, for example, grant chinese utility model patent that bulletin number is CN207261379U discloses a valve switch sign hanger, include the split ring with the opening down that hangs the hanger body on corresponding valve hand wheel, the opening that is used for hanging the sign has the sign flying piece of certain radian and the "U" type fastener of horizontal setting up, the wherein one end of split ring and sign flying piece is connected respectively on the top on the both sides of "U" type fastener, make split ring and sign flying piece opening direction relative, under user state, the other end of split ring and sign flying piece is buckled with "U" type fastener respectively.
During the use, the sign hangs on the valve hand wheel through the hanger, consequently must take sign and hanger off earlier when switch valve, and the operation is accomplished the back and is rotatory a tablet face with the sign, hangs again on the hand wheel, and the shortcoming is that all must take off the sign from the valve at every turn, need make a round trip to take off hang, rotatory, and operating procedure is many, complex operation.
Therefore, when the valve switch state indicator in the prior art is used, the indicator must be taken down firstly, and then the indicator is mounted on the valve again after being turned over, so that the operation is troublesome.
