Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below
In conjunction with detailed description of the invention, this utility model is expanded on further.
Referring to figure, this utility model provides a kind of technical scheme: a kind of natural gas well start stop apparatus, including cylinder body 1,
Cylinder body 1 is made up of nonmagnetic substance.Being provided with in cylinder body 1 can be along its piston 2 in axial sliding, and cylinder body 1 inwall is provided with packing 16,
Realize between piston 2 and cylinder body 1 inwall airtight by packing 16.In cylinder body 1, the right side of corresponding piston 2 is divided into low pressure chamber 3, corresponding
The left side of piston 2 is high pressure chest 4, and cylinder body 1 is provided with the low pressure chamber intake valve 5 corresponding with low pressure chamber 3 and relative with high pressure chest 4
The high pressure chest intake valve 6 answered.Gas communication after low pressure chamber intake valve 5 and well head throttling, i.e. gas after well head expenditure and pressure
In low pressure chamber 3 can being entered by low pressure chamber intake valve 5 and promote piston 2 to move to high pressure chest 4；High pressure chest intake valve 6 and well head
Gas before throttling communicates, i.e. gases at high pressure before well head throttling are entered in high pressure chest 4 by high pressure chest intake valve 6, and promote
Piston 2 moves to low pressure chamber 3.
Piston 2 both sides are embedded with drive a well magnet steel 7 and closing well magnet steel 8, meanwhile, cylinder on the circumference of endface position respectively
Body 2 outer wall be provided with respectively with magnet steel 7 and corresponding drive a well magnetic induction valve 9 and the closing well magnetic induction valve 10 of closing well magnet steel 8 of driving a well,
When drive a well magnet steel 7 with drive a well magnetic induction valve 9 position relative to time, the magnetic induction valve 9 that drives a well opens, when closing well magnet steel 8 and closing well magnetic strength
Answer valve 10 position relative to time, closing well magnet steel valve 10 is opened.Drive a well magnetic induction valve 9 and closing well magnetic induction valve 10 respectively by respective
Pipeline is connected with the pneumatic operated valve 11 controlling well head opening and closing.
When gas well mouth pressure rises, well head gas enters in high pressure chest 4 through pressure guiding pipeline and high pressure chest intake valve 6,
High pressure chest 4 internal gas pressure rises therewith and promotes piston 2 to move to low pressure chamber 3, when piston 2 moves to the limit to low pressure chamber 3 direction
During position, the magnet steel 7 that the drives a well magnetic induction valve 9 that makes to drive a well is opened so that the pipeline and the pneumatic operated valve 11 that connect with the magnetic induction valve 9 that drives a well close
Valve side inside cylinder power diarrhea due to stagnation of QI is put, and now, pneumatic operated valve valve opening side cylinder internally-powered gas promotes pneumatic operated valve 11 to open, thus, gas well
Open.After gas well drives a well, well head pressure is gradually reduced, and high pressure chest 4 internal gas pressure reduces, and the pneumaticpiston 2 in low pressure chamber 3 is to high pressure
Cavity direction moves, and when gas pressure is less than setting value in low pressure chamber, enters the gas in low pressure chamber 3 by low pressure chamber intake valve 5
Body can make piston 2 can continue to move to high pressure chest 4 direction, when piston 2 moves to extreme position to high pressure chest 4 direction, and closing well
Magnet steel 8 makes closing well magnetic induction valve 10 open, dynamic in the pipeline connected with closing well magnetic induction valve 10 and pneumatic operated valve 11 valve opening side cylinder
Strength is released, and now, pneumatic operated valve 11 closes valve side cylinder internal gas pressure and promotes pneumatic operated valve 11 to cut out, thus reaches closing well purpose.
Therefore, natural gas well start stop apparatus of the present utility model is with gas well mouth gas as power, according to well head pressure
It is automatically obtained and drives a well and closing well, be greatly saved manpower.
Cylinder body 1 is provided with and the bleeder valve 12 corresponding to low pressure chamber 3, low pressure chamber 3 is additionally provided with Pressure gauge 18, for right
Low pressure chamber carries out pressure and shows, when low pressure chamber 3 internal gas pressure is higher than setup pressure value, bleeder valve 12 is opened super in low pressure chamber 3
High pressure is released.
Cylinder body 1 uses split-type structural, is made up of low pressure cylinder body 14 and high pressure cylinder body 15, low pressure cylinder body 14 and high pressure cylinder body
15 is corresponding with low pressure chamber 3 and high pressure chest 4 respectively.Pass through screw thread between low pressure cylinder body 14 and high pressure cylinder body 15 or Flange joint is real
The most detachable.Being provided with stopping step 17 in low pressure cylinder body 14 and high pressure cylinder body 15, stopping step 17 is for work
The shift position of plug 2 limits, and will be unable to continue to move to when piston 2 moves to left and right stopping step 17.
The buffer spring 13 that piston 2 is buffered it is equipped with in low pressure chamber 3 and high pressure chest 4.Buffer spring 13 can be right
Piston 2 carries out certain buffering, and piston 2 can also provide certain restoring force simultaneously.Piston 2 is moved through in low pressure chamber 3
Cheng Zhong, when in low pressure chamber 3, pressure rises to setting value, bleeder valve 12 is opened, superelevation of releasing partial pressure, makes piston 2 to hold
Continue and move to low pressure chamber 3, the buffer spring 13 in bleeder valve 12, low pressure chamber and the Pressure gauge 18 in low pressure chamber 3 together decide on
The force value of low pressure intracavity gas, during to ensure that piston 2 moves at the stopping step 17 of low pressure chamber, gas well mouth pressure is just
For the force value driven a well.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described, for
For those skilled in the art, it is clear that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and without departing substantially from this
