Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As Figure 1-3, one is taken precautions against natural calamities and is comprised main valve 1, oil cylinder 2, oil storage tank 3, tubulation 4, flow velocity sensor 5, hand oil pump or Portable electric oil pump 6, heavy hammer mechanism 7, hydraulic circuit 8, connection bracket 9 with urgent intercepter valve (IV).
Main valve 1 is connected by flange bolt with tubulation 4, connection bracket 9 is bolted on main valve 1, oil cylinder 2, oil storage tank 3, hand oil pump or Portable electric oil pump 6 and heavy hammer mechanism 7 are all arranged in connection bracket 9, flow velocity sensor 5 is arranged on tubulation 4 by flange bolt, hydraulic circuit 8 links together hand oil pump or Portable electric oil pump 6, oil cylinder 2, oil storage tank 3, flow velocity sensor 5, and oil storage tank 3 has the double action of oil storage, accumulation of energy.
As shown in Fig. 4-5, main valve 1 comprises valve body 1.1, flap 1.2, major axis 1.3, Withdrawing pin 1.4, minor axis 1.5, leg 1.6.
Valve body 1.1 is connected with minor axis 1.5 by major axis 1.3 with flap 1.2, and fixing by Withdrawing pin 1.4, and leg 1.6 is fixing by bolt and valve body 1.1, and major axis 1.3 is connected and fixed with heavy hammer mechanism 7.
Valve opening:
Under valve closing state, want Open valve, can manually use hand oil pump or Portable electric oil pump 6 to operate, hydraulic circuit 8 becomes valve opening loop, and oil cylinder 2 actions produce oil pressure, and heavy hammer mechanism 7 is promoted, drive flap 1.2 to rotate by major axis 1.3, main valve 1 is opened.
Valve closing:
When valve opening, heavy hammer mechanism 7 is raised simultaneously because Action of Gravity Field also provides pass valve actuation power; Tubulation 4 has ensured the stable of flow velocity sensor 5 front end flow rate of water flow, makes flow velocity sensor 5 sense real change in flow.In the time that downstream line has an accident a large amount of jet flow of generation, the fluid power that the flow measurement sensing plate of the flow velocity sensor 5 in tubulation 4 monitors will substantially exceed predefined normal fluid power, oil circuit now automatically switches, hydraulic oil pipe system 8 becomes valve closing loop, heavy hammer mechanism 7 loses the lifting force of oil cylinder 2, under the effect of gravity, falls, and major axis 1.3 drives flap 1.2 to rotate, main valve 1 is closed, reach the effect of cutting off current guarantee downstream safety.
Urgent intercepter valve (IV) operated by rotary motion is in the underground inspection shaft of distribution reservoir outlet end or in the underground inspection shaft of delivery water pipeline.Flow speed value while normally sending water is generally by the spring mechanism preliminary settlement of flow velocity sensor, in the time there is for various reasons damaged a large amount of water spray in downstream line, because the flow velocity in pipe now will substantially exceed at the fluid power of the flow measurement sensing plate through being built in the flow velocity sensor (being made up of full mechanism part) on tubulation the normal fluid power of originally setting, at this moment flow velocity sense rod drives the actuator of flow velocity sensor, switch oil-way system, make oil circuit switch to main valve and close loop circuit.Main valve flap, under weight effect, divides two sections of speeds to close by the speed travel settings of oil cylinder, to cut off rapidly water source, upstream, guarantees downstream safety.General after main valve is closed completely, if while wanting to reopen, can manual operation be positioned at hydraulic hand-pump or the Portable electric oil pump of valve side, make it to open completely.
