Description
Technical field
The invention belongs to oil field hydraulic fracturing equipment technical fields, are related to a kind of fluid power remote control valve.
Background technology
Shale gas exploitation at present mainly forms chicken-wire cracking to realize page using extensive hydraulic fracturing method on stratum
The volume increase of rock gas well, since depth of stratum is generally at 4000 meters or so, to form a wide range of chicken-wire cracking, operational discharge capacity generally exists
14-16m3/ min, bottom hole fracturing pressure (BHFP) is high, and operation pressure is high, and the single hop construction time is long, and generally up to pressure can reach 95-
97MPa, 6-7m when far above conventional pressure break3/ min discharge capacities and 60-70MPa pressure, thus ground high pressure pipe joint bears pressure
Height, to avoid maloperation that construction accident occurs, maintenance needs convenient to overhaul are pacified between hydraulic fracturing pump truck and high pressure pipe joint simultaneously
Fill high pressure cock.
In the previous method mainly using the opening and closing of manpower manual control high pressure cock valve door, construction personnel needs
It opens the plug valve on high pressure pipe joint manually into higher-pressure region and realizes that the method for being turned on and off cock has been difficult to realize, not only
To personal safety generation seriously threaten, in During manual operation the erroneous judgement of cock state cause construction accident and construction fail
The case where happen occasionally, accident impact range is big, consequence is serious, need consider can be with remote-operated valve.
Invention content
The object of the present invention is to provide one kind can be with remote-operated valve.The purpose of the present invention is by the following technical programs
It realizes.
Fluid power remote control valve, including consisting of part：Hydraulic pump, upper cover and shell, the liquid being mounted in shell
Cylinder pressure, positioning pin, position indicator, off-position indicator, rotor and its backing pin of tail portion and cock connection position；Measuring truck control system
System and hydraulic pump telecommunication, hydraulic pump push hydraulic pressure according to the remote control signal of instrument vehicle control by hydraulic oil
Cylinder is moved to different directions；It is directly connected to by positioning pin between hydraulic cylinder and rotor, the elastic drive rotor rotation of hydraulic cylinder
Transhipment is dynamic；Rotor is connect by cock connection position with cock, and rotor drives cock to rotate by cock connection position；When rotor tail portion
Backing pin rotating contact to position indicator or off-position indicator when, hydraulic cylinder stop motion, cock is turned on and off.
Further, remote control signal is current controling signal.Instrument vehicle control remotely sends out electricity to hydraulic pump
Flow control signals, hydraulic pump push hydraulic cylinder to carry out left and right movement, realize rotation according to the difference of current signal by hydraulic oil
Plug is turned on and off.
Further, further include the switch indicator board rotated positioned at upper outer side of lid, as rotor rotates.
The course of work of fluid power remote control valve is as follows：Cock on hydraulic fracturing process mesohigh manifold passes through cock
Connection position is connected with rotor, and instrument vehicle control remotely sends out current controling signal to hydraulic pump, and hydraulic pump is believed according to electric current
Number difference, push hydraulic cylinder to carry out left and right movement by hydraulic oil, when hydraulic cylinder moves downward, due to consolidating for positioning pin
It is set for using, to drive rotor to rotate and then open cock, the high-pressure fluid that hydraulic fracturing pump truck is supplied is made to enter high pressure pipe joint；
And when hydraulic cylinder moves right, rotor can be made to rotate round about, to which cut-out tap prevents high-pressure fluid from entering manifold.
Since switch indicator board can be rotated with the rotation of rotor, unlatching/closed state of cock can be clear by switch indicator board
Mark.It is directly connected to by positioning pin between hydraulic cylinder and rotor, hydraulic cylinder elastic drive rotor rotation as jack
Transhipment is dynamic, and the rotary motion of rotor, cock connecting shaft is driven to pass through in cock connection position and rotor when hydraulic cylinder moves downward
Mandrel connects, and when the backing pin rotating contact of rotor tail portion is to position indicator, hydraulic cylinder stop motion, at this time cock is opened.
Otherwise rotor negative direction rotary motion is driven when moving right when hydraulic cylinder, when the backing pin rotating contact of rotor tail portion is to off-position
When indicator, hydraulic cylinder stop motion, at this time cock is closed.
The present invention is easy to operate, safety may be implemented using steady reliable hydraulic control to high pressure cock unlatching/pass
Personal safety has been effectively ensured without being operated manually into higher-pressure region in the remote control closed, site operation personnel.
The present invention avoids the erroneous judgement to cock state to the real-time display of cock unlatching/closed state, to effectively
It ensure that being normally carried out for pressing crack construction, can effectively improve construction speed, avoid the generation of construction accident.

Specific implementation mode
Below in conjunction with attached drawing, the present invention will be further described.
As shown in Figure 1, fluid power remote control valve 1, including consisting of part：Upper cover 2 and shell 7 are mounted on shell 7
Interior hydraulic cylinder 4, positioning pin 5, position indicator 9, off-position indicator 10, rotor 6 and its backing pin of tail portion and cock connection position
8, and positioned at 2 outside of upper cover, the switch indicator board 3 of rotation with the rotation of rotor 6；By fixed between hydraulic cylinder 4 and rotor 6
Position pin 5 is directly connected to, 4 elastic 6 rotary motion of drive rotor of hydraulic cylinder；The connecting shaft of cock by cock connection position 8 with
The center axis connection of rotor, rotor 6 drive cock to rotate by cock connection position 8；When the backing pin rotating contact of 6 tail portion of rotor arrives
When position indicator 9 or off-position indicator 10,4 stop motion of hydraulic cylinder, cock opens or closes.
As shown in Fig. 2, the course of work of fluid power remote control valve 1 is as follows：On hydraulic fracturing process mesohigh manifold
Cock is connected by cock connection position 8 with rotor 6, electronic remote signal control hydraulic cylinder 4 move reciprocatingly, when hydraulic cylinder 4 to
When left movement, since the fixed function of positioning pin 5 makes hydraulic fracturing pump truck supply to drive rotor 6 to rotate and then open cock
The high-pressure fluid answered enters high pressure pipe joint；And when hydraulic cylinder 4 moves right, rotor 6 can be made to rotate round about, to close
Closing cock prevents high-pressure fluid from entering manifold.Since switch indicator board 3 can be rotated with the rotation of rotor 6, the unlatching of cock/
Closed state can clearly be identified by switch indicator board 3.It is directly connected to by positioning pin 5 between hydraulic cylinder 4 and rotor 6, hydraulic pressure
Elastic 6 rotary motion of drive rotor as jack of cylinder 4 drives the rotation fortune of rotor 6 when hydraulic cylinder 4 travels forward
Dynamic, the connecting shaft of cock is by the center axis connection of cock connection position 8 and rotor, when the backing pin rotating contact of 6 tail portion of rotor arrives
When position indicator 9,4 stop motion of hydraulic cylinder, at this time cock is opened.Otherwise when hydraulic cylinder 4 drives rotor 6 when moving right
Negative direction rotary motion, when the backing pin rotating contact of 6 tail portion of rotor is to off-position indicator 10,4 stop motion of hydraulic cylinder, at this time
Cock is closed.
As shown in figure 3,12 tele-control system of measuring truck controls hydraulic pump 11 provides having for different directions to hydraulic cylinder 4
The hydraulic oil of certain pressure realizes the opening and closing of remote control cock to push hydraulic cylinder 4 to do flexible reciprocating motion.
