Abstract
The utility model belongs to the technical field of oil and gas collection equipment in an oil and gas field, and particularly relates to an electric throttling pressure reducing valve. The electric throttling pressure reducing valve is characterized in that a pressure sensor is arranged between a high-pressure connector and a low-pressure connector of a throttling pressure reducing valve; an electric actuator is arranged between a manual wheel of the throttling pressure reducing valve and a valve rod; both the pressure sensor and the electric actuator are connected with a control system. The throttling pressure reducing valve comprises a valve body and internals, which are common in the field; the internals comprise an O-ring, a throttling valve base, a valve rod, an octagonal backing ring, a bonnet, a nut, a bolt, a supporting seat, a screw, a feather key, a packing pressing cap, sealing filler and the like. The electric throttling pressure reducing valve disclosed by the utility model is safe and reliable, and a low-pressure line does not crack due to sudden increase of pressure of the pressure line; the production is stable, and the normal production is not influenced by the change of the pressure.
Description
Technical field
The utility model belongs to oil gas field oil gas collection equipment technical field, is specifically related to a kind of electric throttling reduction valve.
Background technique
After oil-gas mining, oil gas need be collected and focus on through pipeline, and is high pressure from underground mining oil gas out, needs decompression and pressure is controlled at and in a lower scope, then carries out other processing in subsequent processes.That common reduction valve has manual control and on high pressure line, mix safety valve and be no more than certain value to control high pressure pressing.When pressurized gas are stable, after the good Pressure reducing ratio of manual tune, can normally produce, yet when pressurized gas are during in unsettled fluctuation, Pressure reducing ratio also can constantly change, fluctuating, larger that low-pressure line is produced to the danger of line is larger or surpass certain value safety valve and can automatically close, and impact is production normally.
Summary of the invention
The utility model provides a kind of electric throttling reduction valve, controls the action of electric actuator by pressure transducer and control circuit, to realize the object of decompression automation, guarantees safety.
The technological scheme that the technical problem that the utility model solves adopts is: electric throttling reduction valve, comprise expenditure and pressure valve, it is characterized in that being provided with pressure transducer at high voltage interface and the low-voltage interface place of expenditure and pressure valve, between the manual pulley of expenditure and pressure valve and valve rod, be provided with electric actuator; Described pressure transducer is all connected with control system with electric actuator.
Usually, described expenditure and pressure valve comprises the known valve body in this field and internals, and internals comprise "O"-ring, throttle valve seat, valve rod, anistree gasket ring, valve gap, nut, bolt, supporting base, screw, feather key, packing pressure cap and stuffing box packing etc.
The utlity model has following advantage:
1, safe and reliable, can not cause because pressure line pressure increases suddenly low-pressure line fracture.
2, produce and stablize, can normally not produce because of pressure variable effect.
Accompanying drawing explanation
Fig. 1, be the utility model embodiment electric throttling reduction valve linkage structure schematic diagram.
Fig. 2, be the structural representation of expenditure and pressure valve in the utility model embodiment.
In figure, 1-valve body, 2-"O"-ring, 3-throttle valve seat, 4-valve rod, the anistree gasket ring of 5-, 6-valve gap, 7-nut, 8-bolt, 9-supporting base, 10-screw, 11-electric actuator, 12-feather key, 13-packing pressure cap, 14-stuffing box packing, 15-high pressure line, 16-low-pressure line, 17-pressure transducer I, 18-manual pulley, 19-control system, 20-pressure transducer II.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is further illustrated.
Embodiment: the present embodiment electric throttling structure of relief pressure valve is as shown in attached Fig. 1 and 2, comprise expenditure and pressure valve, its main feature is to be provided with pressure transducer (20) at the high voltage interface place of expenditure and pressure valve connection high pressure line (15), the low-voltage interface place that connects low-pressure line (16) is provided with pressure transducer (17), between the manual pulley of expenditure and pressure valve (18) and valve rod (4), is provided with electric actuator (11); Pressure transducer I (17), pressure transducer II (20) and electric actuator (11) are all connected with control system (19).
Expenditure and pressure valve in embodiment as shown in Figure 2, mainly comprises: valve body (1), "O"-ring (2), throttle valve seat (3), valve rod (4), anistree gasket ring (5), valve gap (6), nut (7), bolt (8), supporting base (9), screw (10), electric actuator (11), feather key (12), packing pressure cap (13), stuffing box packing (14).
Embodiment operates like this: the initial stage first rotates handwheel (18) regulating valve stem (4) and moves up and down, to regulate the interior force value of low-pressure line (16) in the value requiring, opening control (19), and set low-pressure line (16) range of working pressure.Pressure when high pressure line (15) internal pressure changes in low-pressure line (16) also can change, now pressure transducer II (20), pressure transducer I (17) can send signal to control system (19) and setting value comparison, when the value of pressure transducer II (20) is greater than design load, when when a little, the value of pressure transducer I (17) is also large than setting value, control system (19) will be controlled electric actuator (11) rotation by valve rod (4) backspin, to reduce throttle diameter, realize pressure-reducing function; When the value of pressure transducer II (20) is greater than design load, and pressure transducer I (17) will be controlled electric actuator (11) than setting value hour control system (19) and rotate and will on valve rod (4), revolve, and to increase throttle diameter, realize boost function; When the value of pressure transducer (20) is less than or equal to design load, control system (19) will be controlled electric actuator (11) and be opened to upper limit position switch place.
