Long -range automatically controlled compression relief valve of hydraulic fracturing includes: automatically controlled starter motor, connection pad, high -pressure cock and remote control case, the high pressure cock is passed through in the connection pad open the valve with automatically controlled starter motor is connected, the control of remote control case the start -up of automatically controlled starter motor or close. The high pressure cock is equipped with the pressure sensing device, the pressure sensing device will the pressure data transmission of high pressure cock department arrives the remote control case. Be equipped with display device on the remote control case, display device shows opening or the closed condition of high pressure cock. The utility model discloses easy and simple to handle, safety can realize the remote control that opens / close high -pressure cock, and on -the -spot constructor need not to get into high nip and carries out manually operation, has effectively guaranteed the personal safety.
Description
Technical field
This utility model belongs to oil field fracturing apparatus field, relates to a kind of fracturing remote electrically controlled compression relief valve.
Background technology
Shale gas exploitation at present is main uses extensive hydraulic fracturing method in stratum formation chicken-wire cracking thus to realize shale gas well
Volume increase, due to depth of stratum typically at about 4000 meters, for forming chicken-wire cracking on a large scale, operational discharge capacity typically exists
14-16m3/ min, bottom hole fracturing pressure (BHFP) is high, and operation pressure is high, and the single hop engineering time is long, and generally up to pressure can reach 95-97MPa,
Far above 6-7m during conventional pressure break3/ min discharge capacity and 60-70MPa pressure, thus ground fracturing equipment bears pressure height,
Form dangerous high pressure around well head and in high pressure pipe joint and pipeline, in work progress and construction terminate after need release
Highly pressurised liquid in well head, high pressure pipe joint, pipeline could realize the maintenance maintenance to equipment.
Main employing Non-follow control high pressure cock pressure release in conventional method, workmen need to enter higher-pressure region manual unlocking pressure release
Cock realizes the method for pressure release and is difficult to, and not only personal safety is produced serious threat, revolves in During manual operation
The erroneous judgement of plug-like state causes construction accident and failed situation of constructing to happen occasionally, and accident impact scope is big, consequence serious, needs
Consider the pressure relief equipment that can remotely operate and monitor.
Summary of the invention
The purpose of this utility model is to provide a kind of long-range control, the remote electrically controlled compression relief valve of safe and reliable fracturing.
The purpose of this utility model is achieved through the following technical solutions.Fracturing remote electrically controlled compression relief valve, including: automatically controlled
Starter motor, connection dish, high pressure cock and long-range control chamber, described high pressure cock by the unlatching valve in described connection dish with described
Electric control starting machine connects, and described long-range control chamber controls startup or the cut out of described electric control starting machine.
Further, described high pressure cock is provided with pressure sensor device, and described pressure sensor device is by the pressure at described high pressure cock
Force data is transferred to described long-range control chamber.
Further, described long-range control chamber is provided with display device, described display device show described high pressure cock unlatching or
Person's closed mode.
When touching by the green start button of long-range control chamber, electric control starting machine starts and cock is opened and carries out pressure release, works as cock
Display lamp length is opened bright after fully opening；When touching the red X button by long-range control chamber, electric control starting machine reversely rotates will
High pressure cock is closed, and closes display lamp length bright, owing at this moment cock is turned off, it is ensured that pressure after completely closing high pressure cock
Being normally carried out of construction.
This utility model is easy and simple to handle, safety, it is possible to achieve the long-range control opened high pressure cock/close, site operation personnel
It is operated manually without entering higher-pressure region, personal safety has been effectively ensured.
This utility model avoids the erroneous judgement to cock state to the display in real time of cock unlatching/closed mode, thus is effectively ensured
Being normally carried out of pressing crack construction, can be effectively improved construction speed, it is to avoid the generation of construction accident.
Accompanying drawing explanation
Accompanying drawing is fracturing of the present utility model remote electrically controlled compression relief valve schematic diagram.
Reference: 1-electric control starting machine, 2-connection dish, 3-high pressure cock, the long-range control chamber of 4-, 5-opens valve, and 6-closes
Display lamp, 7-opens display lamp, 8-X button, 9-start button.
Detailed description of the invention
It is described further below in conjunction with accompanying drawing compression relief remote electrically controlled to fracturing of the present utility model valve.
Fracturing remote electrically controlled compression relief valve, including: electric control starting machine 1, connection dish 2, high pressure cock 3 and remotely control
Case 4, high pressure cock 3 is connected with electric control starting machine 1 by the unlatching valve 5 in connection dish 2, and long-range control chamber 4 controls automatically controlled
The startup of starter motor 1 or closedown also show its unlatching/closed mode.When touching the green start button 9 by long-range control chamber, electricity
Control starter motor 1 starts and high pressure cock 3 is opened and carries out pressure release, opens display lamp 7 long bright after cock 3 fully opens；When
When touching the red X button 8 by long-range control chamber 4, electric control starting machine 1 reversely rotates closes high pressure cock 3, closes completely
Display lamp 6 is closed long bright, owing at this moment high pressure cock is turned off, it is ensured that normally entering of pressure construction after closing high pressure cock 3
OK.This utility model carries out pressure release control by long-range control chamber to high pressure cock, and ground high-pressure is able to safe release, executes
Workman person is no longer necessary to enter dangerous higher-pressure region, and cock unlatching/closed mode is shown normally, effectively prevent by control chamber display lamp
The generation of erroneous judgement situation.
