Description
Technical field
It the utility model is related to a kind of novel valve stem travel switch instruction device, and in particular to one kind can indicate that valve is beaten
The new device of open and close position.
Background technology
At present, conventional valve rod travel switch indicating device be by support, valve rod, instruction folder, outer-hexagonal bolts assemblies and
Into.Technical scheme is used by this device：One section of groove of processing at valve rod polished rod, instruction clamp cutting forming, outer six
Corner bolt is fixed in stem groove, and the side processing U-type groove of support, instruction folder points to support side through support U-type groove.
Indicate that folder pointed location reflects the opening and closing position of valve rod.The instruction device of the structure is integral type, in large diameter valve
The device is used on door, because length is longer, it is necessary to which very big one block of steel plate carrys out wire cutting, steel plate utilization ratio is relatively low, wastes system
Cause this.Further, since the device is longer, and needs guiding through support U-type groove, do not allow in assembling easy to operate；After mounting, valve
Under open mode, due to the influence of instruction device, suspender belt can not lift by crane valve, it is necessary to dismantle instruction device, dismantle, installed
Journey is again cumbersome, greatly reduces operating efficiency.
Utility model content
In order to overcome the manufacturing cost of existing valve switch stroke indicating device high, the problem of installation, disassembling section difficulty,
The utility model provides a kind of novel valve switch over travel instruction device.The device is not only high to steel plate utilization ratio, substantially reduces
Manufacturing cost, and dismantle, be easy for installation, lifting is convenient, largely improves operating efficiency.
Technical scheme is as follows used by the utility model solves its technical problem：
The instruction folder is made up of the half part of left and right two, and left side is square end, and right side is tapering point, in left side hexagonal spiral shell
Bolt A will be indicated in the fit that is fixed on valve rod of folder, and indicating arm passes through the U-type groove of support, indicating arm by external screw thread with
Indicate that the internal thread hole of folder is assembled, indicating arm is fixed on valve rod, pointer is fixed on the indicating arm right side by hex bolts B
End.
Further instruction, the instruction folder right side tapering point is provided with an internal thread hole, to install indicating arm.
Further instruction, instruction folder portion point are formed by steel plate wire cutting.
Further instruction, indicating arm one end are external screw threads, and the internal thread hole cooperation of external screw thread and instruction folder is installed, another
End sets internal thread hole, coordinates installation that pointer is fixed with hex bolts B, the indicating arm is process by bar.
The beneficial effects of the utility model are：Instruction folder portion point is formed by steel plate wire cutting, and instruction bar part is added by bar
Work forms, and steel plate effective rate of utilization is high, and instruction folder portion separation structure is shorter, easy for installation.After instruction folder is fixedly mounted, indicating arm is still
It can at any time dismantle, not influence the lifting of valve.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of instruction folder.
Fig. 3 is the schematic diagram of indicating arm.
In figure, 1 it is hex bolts A, 2 is instruction folder, 3 is valve rod, 4 is locking nut, 5 is indicating arm, 6 is support, 7 is
Pointer, 8 are hex bolts B.
Embodiment
As shown in figure 1, a kind of novel valve stem travel switch instruction device, including hex bolts A1, instruction folder 2, valve rod 3,
Locking nut 4, indicating arm 5, support 6, pointer 7, hex bolts B8, the instruction folder 2 are made up of the half part of left and right two, and left side is
Square end, right side are tapering point, will indicate to press from both sides in 2 fits being fixed on valve rod 3 in left side hex bolts A1, instruction
Bar 5 passes through the U-type groove of support 6, and indicating arm 5 is assembled by the internal thread hole of external screw thread and instruction folder 2, indicating arm 5 is consolidated
It is scheduled on valve rod 3, pointer 7 is fixed on the right-hand member of indicating arm 5 by hex bolts B8.
As shown in Fig. 2 describing the structure of instruction folder 2 in detail, emphasis is characterized in that 2 one end of instruction folder are provided with an internal thread
Hole, to install indicating arm 5.
As shown in figure 3, describing the structure of indicating arm 5 in detail, emphasis is characterized in that the one end of indicating arm 5 is external screw thread, outer spiral shell
The internal thread hole of line and instruction folder 2, which coordinates, to be installed, and the other end sets internal thread hole, coordinates installation by pointer 7 with hex bolts B8
It is fixed, the indicating arm 5 is process by bar, simple in construction.
In summary, the utility model overall structure is simple, easy to process, and 2 parts of instruction folder are formed by steel plate wire cutting,
Steel plate effective rate of utilization is high, and the part of indicating arm 5 is process by bar, and instruction 2 part-structures of folder are shorter, easy for installation.Instruction
After folder 2 is fixedly mounted, indicating arm 5 can still be dismantled at any time, not influence the lifting of valve, be the preferred instruction of general large bore valves
Device.
For above-mentioned embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with this skill
The personage of art can understand content of the present utility model and be carried out, and protection model of the present utility model can not be limited with this
Enclose, all equivalent change or modifications made according to the utility model Spirit Essence, should all cover in protection model of the present utility model
In enclosing.
