Description
Technical field:
The utility model relates to the detection of on off state when valve moves in the chemical production equipment, is specially adapted to large-scale oil(pressure)brake plate valve.
Background technology:
The detection of on off state was mainly adopted near switch and mercury cut-off when existing gas making valve moved, and its fixed in place does not have unified pattern.A kind of valve checking device is arranged at present, it is that lever one end at a lever support contacts with the valve web member, the other end at lever is installed a sensing head, installing one near switch near the place of sensing head, be connected near there being signal conductor to control the display part on the switch with indoor signal reception.This valve checking device need be changed parts and maintenance frequently owing to be subjected to valve to examine on-the-spot hot environment and near the influence of switch performance, be difficult to guarantee the accuracy and the reliability of valve inspection, the integrated cost height, and serviceable life is short.
Summary of the invention:
The purpose of this utility model is that a kind of valve of design is examined performance accurately and reliably, long service life, the valve switch condition checkout gear that integrated cost is low.
The technical solution of the utility model is finished as follows, this valve switch condition checkout gear includes a lever dolly, it is characterized in that: the adjustable contact rod end at lever dolly is equipped with strong magnet, the below of adjustable contact lever is provided with gag lever post, keeps certain intervals to be fixed with a magnetic-type inductive switch by U type frame in the outside of strong magnet.Above-mentioned magnetic-type inductive switch is the magnetic spring of packing in an outside surface has the copper pipe of insulation sheath, magnetic spring two ends in copper pipe are spacing fixing with the insulation limit plunger, on magnetic spring front end and copper pipe wall, draw a lead respectively, seal with the silica gel plug respectively at the copper pipe two ends, between insulation limit plunger in its back-end and the silica gel plug Tetrafluoro spacer is arranged, fill with transformer oil in the copper pipe of sealing, two leads are connected into light emitting diode and are connected with conductor terminal row with computing machine joint input fastener with one kilovolt of resistance in indoor loop.The utility model has adopted magnetic-type inductive switch and improved valve inspection support, when detecting valve, as long as valve being examined the lever arm end and the valve web member of support is movably connected, strong magnet that can be by being located at the support other end away from valve is delivered to the signal that opens or closes of magnetic-type inductive switch in the indoor computing machine, detect accurately and reliably, the parts long working life reduces comprehensive use cost widely.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is a kind of structural representation of magnetic-type inductive switch, and Fig. 3 is the annexation figure of computing machine input fastener in magnetic-type inductive switch and the pulpit.Among the figure, 1. lever dolly, 2. lever arm, 3. lever pillar, 4. gag lever post, 5. adjustable length contact lever, 6. strong magnet, 7. lead, 8. magnetic-type inductive switch, 9.U type frame, 10. lead, 11. computing machine contacts input fastener, 12. conductor terminals row.The limit plunger 8-0. insulation sheath, 8-1. copper pipe, 8-2. magnetic spring, 8-3. transformer oil, 8-4. insulate, 8-5. Tetrafluoro spacer, 8-6. silica gel plug.
Embodiment:
The utility model is to improve near the basis of switch in existing lever dolly formula, at first be that the contact lever of lever dolly 1 is become length-adjustable contact lever 5, be fixed with strong magnet 6 in its end, a gag lever post 4 is established in the below of adjustable contact lever, and the minimum altitude of restriction contact lever moves to make things convenient for lever.Keep certain intervals to fix a magnetic-type inductive switch 8 in the outside of strong magnet by U type frame 9 and contact lever vertical-horizontal.Above-mentioned magnetic-type inductive switch is the magnetic spring 8-2 that packs in an outside surface has the copper pipe 8-1 of insulation sheath 8-0, magnetic spring two ends in copper pipe are fixed with insulation limit plunger 8-4 and the spacing insulation of copper pipe, on spring front end and copper pipe rear end sidewall, respectively draw a lead 7, the respectively silica gel plug 8-6 sealing at the copper pipe two ends also accompanies Tetrafluoro spacer 8-5 between the limit plunger of rear end and silica gel plug.Filled with transformer oil 8-3 in the copper pipe of spacing sealing, being connected with light emitting diode on the lead of an end can be connected with indoor computing machine joint input fastener 11, and other end lead inserts one kilovolt of resistance can be incorporated in the indoor conductor terminal row 12.Its principle of work is, when strong magnet during near the magnetic-type inductive switch, the stressed back of magnetic spring takes place to be shifted and contacts with tube wall is interior in managing, make the connecting circuit conducting, light emitting diode is bright in the loop, pulpit inner contact input fastener received signal, it is bright that the inspection of microcomputer valve changes display lamp, when strong magnet during away from the magnetic force induction switch, stationary state is stablized in magnetic spring very fast recovery under the drag effect of elastic force and transformer oil, and the loop disconnects, and pilot lamp in the loop (light emitting diode) does not work, pulpit inner contact input fastener acknowledge(ment) signal, the inspection of microcomputer valve changes display lamp and does not work.
