Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, the present embodiment provides a kind of remote control type Emergeny Cutoff Valves, comprise the mechanism case 2, valve gap 18 and the valve body 1 that connect successively from top to bottom, be provided with valve port 21 in valve body 1 and cut off valve head 20, cut off between valve head 20 and valve gap 18 and be provided with main spool spring 19, be provided with the mechanical shut off mechanisms 11 for controlling to cut off valve head 20 close port 21 in mechanism case 2, mechanical shut off mechanisms 11 comprises positive stop hook 6, limiting stopper 10, movable lance 12 and slide block rod assembly.Slide block rod assembly is made up of pull bar 17 and the slide block 16 being fixed on pull bar 17 upper end, and pull bar 17 lower end is fixedly connected with valve head through valve gap 18.
Be provided with on the left of mechanism case 2 and be communicated with valve body 1 for setting downstream cut-out pressure value and monitoring valve port 21 and downstream pressure and feed back to the pressure monitor alarm 5 of central control chamber, being provided with the long-range cutting-off controlling device 8 for receiving central control chamber remote control signal above pressure monitor alarm 5, on the right side of long-range cutting-off controlling device 8, being provided with the pushing component 7 for promoting mechanical shut off mechanisms 11, cut-out valve head 20 being closed through mechanism case 2.
The on-the-spot cutting-off controlling device 14 be connected with pressure governor outlet pressure signal pipe is installed on the right side of mechanism case 2, in on-the-spot cutting-off controlling device 14, is provided with monitoring film.Movable lance 12 is connected with on-the-spot cutting-off controlling device 14 through mechanism case 2, is provided with spring 13 between on-the-spot cutting-off controlling device 14 and mechanism case 2.Be provided with the valve position monitoring alarm 4 for valve position action being fed back to central control chamber in mechanism case 2, valve position monitoring alarm 4 is provided with and contacts with the roller 15 of monitoring and cutting-off valve head 20 valve position action with slide block 16.
Valve position monitoring alarm 4, pressure monitor alarm 5 are all connected with central control chamber by cable with long-range cutting-off controlling device 8, and long-range cutting-off controlling device 8 is provided with above the anti-explosion terminal box 9 be communicated with mechanism case 2 for laying cable.Be provided with the fitting seat 3 for fixing valve position monitoring alarm 4 in mechanism case 2, valve position monitoring alarm 4 is connected with valve position monitoring alarm 4 by fitting seat 3.
In implementation process, under normal operating conditions, the gas pressure at on-the-spot cutting-off controlling device 14 place is by pressure governor outlet pressure signal pipe feedback effect monitoring film therein, and this active force and the spring 13 preset act on the balance that the active force monitored on film reaches more accurate.Now, positive stop hook 6 keeps buckling with the limiting stopper 10 in mechanical shut off mechanisms 11, slide block 16 keeps in touch with the roller 15 in valve position monitoring alarm 4, cut off valve head 20 under the pulling force effect of pull bar 17, slide block 16, overcome the elastic force of main spool spring 19 and be in complete opening state always, the import of valve body 1 upstream is normally to the outlet air feed in downstream.
When causing outlet gas pressure P2 raise or be reduced to setting value due to equipment failure or other reason, the effect equilibrium of forces that downstream gas pressure P2 acts on power on on-the-spot cutting-off controlling device 14 internal control film and spring 13 is broken, movable lance 12 will move axially shake-up mechanical shut off mechanisms 11 left makes limiting stopper 10 and positive stop hook 6 throw off, rapid close port 21 is to cut off air-flow under the elastic force effect of main spool spring 19 to cut off valve head 20, and the import of upstream stops the outlet air feed to downstream.Now, slide block 16 is thrown off with the roller 15 in valve position monitoring alarm 4, and valve position action is fed back to central control chamber by valve position monitoring alarm 4, thus the function playing valve position monitoring and report to the police.After valve port 21 is closed by cut-out valve head 20, outlet pressure P2 acts on valve position monitoring alarm 5 by valve body 1, and this pressure signal is fed back to central control chamber by valve position monitoring alarm 5, thus plays the function of pressure monitor and warning.
When on-the-spot cutting-off controlling device 14 lost efficacy or occur that other is abnormal, monitor staff can at central control chamber by pressure monitor alarm 5 remote setting downstream cut-out pressure value.When downstream pressure P 2 departs from setting value, instruction can be sent manually or automatically at central control chamber, order about long-range cutting-off controlling device 8 and touch mechanical shut off mechanisms 11, make cut-out valve head 20 close port 21 to cut off air-flow, thus play maltilevel security protective action.
Above-mentioned mode of execution is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
