The specific embodiment
Figure 1 shows that the structural representation of the utility model remote measuring and controlling safety shut-off valve.
The concrete remote control gas well of implementing is gone into operation
First, open high pressure hand-operated valve (25), close high pressure hand-operated valve (28) and (31).When high-pressure natural gas is entered in safety shut-off valve by inlet end flange (24), natural gas is by high pressure hand-operated valve (25), often open high-pressure solenoid valve (23) and enter piston (17) top of cylinder (12), now high pressure hand-operated valve (28) and normally closed high-pressure solenoid valve (27) are in closed condition, and the cylinder air vent (10) of piston (17) bottom communicates with atmosphere, form pressure reduction, natural gas promotion is further compressed at the cluster spring (14) of preloading condition, pull switch pull bar (9) is downward simultaneously, drive parallel valve plate (8) to bottom offset, until open safety shut-off valve completely, gas well drops into normal production, as shown in Figure 3.
The concrete gas well remote control closing well of implementing
By digital management center, gas field, send instruction, by well head data transmission equipment (37), by command to programmable logic controller (36), then by programmable logic controller, send instruction: often open high-pressure solenoid valve (23) energising and close source of the gas, order normally closed high-pressure solenoid valve (27) energising to be opened simultaneously, bleed off the natural gas in piston (17) upper cylinder, under the effect of cluster spring (14), piston (17) is up, drive switch lever (9) upwards, until parallel valve plate is closed completely, safety shut-off valve completes closing well operation, as shown in Figure 1.Because balancing pole (22) is identical with switch lever (9) diameter, when no matter switch lever still moves upward downwards, it is not subject to the big or small impact of interior pressure, thereby cluster spring (14) only need overcome the frictional force of seal, just pull switch pull bar (9) axially-movable freely, even if gas pressure remains on 1MPa left and right, also can work reliably.
Concrete enforcement super-pressure and ultralow pressure protection
Because the bearing capacity of natural gas multi-purpose station pipeline has a upper safety limit requirement, thereby can not superpressure operation, but can not, lower than a certain lower limit operation, lower than a certain pressure explanation gas well, there is to stop up or occur other problems in multi-purpose station pipeline pressure.Pressure sensing transmitter is transferred to programmable logic controller (36) by the pressure on the number signal of multi-purpose station pipeline, programmable logic controller is provided with the high lower bound of pressure in advance on request, after surpassing, will send instruction, order is often opened high-pressure solenoid valve (23) energising and is closed, normally closed high-pressure solenoid valve (27) energising is opened, and makes safety shut-off valve closing well.
The concrete multi-purpose station pipeline protector of implementing puts into operation again
Natural gas external transport pipeline safety protection apparatus, because there is pipeline break or the operate miss of gas collection treating stations, external transport pipeline safety protection apparatus (38) all can be closed pipeline automatically.Will again drop into, only the high-pressure natural gas of safety shut-off valve and external transport pipeline safety protection apparatus need be bled off, under the effect of back-moving spring, external transport pipeline safety protection apparatus can be resumed work.As external transport pipeline safety protection apparatus is closed, the threshold pression of now data processing centre's acquisition pressure sensing transmitter will approach zero, and now programmable logic controller has completed safety shut-off valve closing well program.Recover the input again of external transport pipeline safety protection apparatus; gas field digital management center instruction normally closed solenoid valve (32) energising is opened; bleed off after the pipe inner high voltage natural gas between safety shut-off valve and multi-purpose station pipeline; external transport pipeline safety protection apparatus resets; order is often opened high-pressure solenoid valve (23) power-off and is opened again; normally closed high-pressure solenoid valve (27) power-off is closed, and recovers gas well and produces.
Enabling of the high pressure hand-operated valve of concrete enforcement
When the power supply (most wells are solar powered assembly) of gas well goes wrong, the effect of each high pressure hand-operated valve is identical with the effect of high-pressure solenoid valve, by high-pressure solenoid valve procedure operation, can complete whole tasks.
