Go down and pull, but when rated operating pressure reaches 15000PSI in well head, since the pressure in well head is very high, manually
Operation is subdued just highly difficult, and therefore, it is necessary to one kind can overcome the fetching device of the above problem.
Utility model content
It is structurally reasonable the purpose of this utility model is to provide a kind of fetching device for high-pressure well mouth, be conducive to
It carries out picking and placing the operation of well head part in high-pressure well mouth.
To achieve the above object, the technical solution of the utility model is to design a kind of fetching device for high-pressure well mouth,
Including cylinder body, it is slidably connected at the intracorporal elevating lever of cylinder, and set on elevating lever lower end and the pick-and-place connector outside cylinder body；
The cylinder body includes the first cylinder body and the second cylinder body arranged up and down, and first flange is equipped on the outside of first cylinder base, should
The first sealing gland is equipped on the inside of first cylinder base, the second cylinder body top outer is equipped with second flange, second cylinder body
Inside top is equipped with the second sealing gland, the first flange and second flange and is connected by a pair of of screw rod；The fetching device
It further include first pressure gauge, bleeder valve, the first control valve and the second control valve, the first pressure gauge and bleeder valve pass through respectively
Pipe fitting is connected to the first cylinder interior, and first control valve and the second control valve pass through pipe fitting and the second inner chamber of cylinder block company respectively
Logical, first control valve is connect by pipe fitting with first pressure gauge, is connected with second pressure gauge on second control valve.
Preferably, cylinder cap is equipped at the top of first cylinder body, which is equipped with hanging ring.
Preferably, second cylinder base is equipped with union plug, which is connected with union spiral shell matched with its
It is female.
Preferably, between first sealing gland and the first cylinder body and between the second sealing gland and the second cylinder body
Equipped with sealing ring.
The working principle of the utility model are as follows: by increasing control valve, bleeder valve and pressure gauge, form pressure circuit.?
When being put into well head part, the pressure in well is guided at the top of elevating lever by pressure circuit, well head part is directly lowered into well
Mouth is internal, adjusts pressure balance, is packed into well head part.When taking out well head part, by the pressure releasing of pressure circuit, well is utilized
Mouth internal pressure, well head part is taken out.
Having the beneficial effect that for the use of the new type is conducive to carry out in high-pressure well mouth to pick and place the operation of well head part.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
The technical solution of the utility model specific implementation is:
As shown in Figure 1, a kind of fetching device for high-pressure well mouth, including cylinder body, it is slidably connected at the intracorporal lifting of cylinder
Bar 1, and set on 1 lower end of elevating lever and the pick-and-place connector 2 outside cylinder body；The cylinder body includes the first cylinder arranged up and down
Body 3 and the second cylinder body 4,3 bottom outside of the first cylinder body are equipped with first flange 5, which is equipped with first
Sealing gland 6,4 top outer of the second cylinder body are equipped with second flange 7, which is equipped with the second sealing
Gland 8, the first flange 5 and second flange 7 pass through a pair of of screw rod 9 and connect；The fetching device further includes first pressure gauge
10, bleeder valve 11, the first control valve 12 and the second control valve 13, the first pressure gauge 10 and bleeder valve 11 pass through pipe fitting respectively
It is connected to inside the first cylinder body 3, first control valve 12 and the second control valve 13 pass through 4 inner cavity of pipe fitting and the second cylinder body respectively
Connection, first control valve 12 are connect by pipe fitting with first pressure gauge 10, are connected with second on second control valve 13
Pressure gauge 14.
Cylinder cap 15 is equipped at the top of above-mentioned first cylinder body 3, which is equipped with hanging ring 16.
Above-mentioned second cylinder body, 4 bottom is equipped with union plug 17, which is connected with union nut matched with its
18。
It is all provided between above-mentioned first sealing gland 6 and the first cylinder body 3 and between the second sealing gland 8 and the second cylinder body 4
There is sealing ring 19.
When being put into well head part, connector 2 will be picked and placed and connect with the well head part of tripping in, bleeder valve 11, first is closed and control
Valve 12 processed and the second control valve 13 are sling entire fetching device by hanging ring 16, by union plug 17, union nut 18 and well
Connecting device links into an integrated entity at the top of mouthful.Then the second control valve 13 is opened, observation second pressure gauge 14 is read, to second pressure
After table 14 shows that pressure is stablized, the first control valve 12 is opened, the pressure value of first pressure gauge 10 constantly increases, meanwhile, elevating lever 1
It moves down, by well head part G.I.H.When taking out well head part, the first control valve 12 is closed, then open bleeder valve 11,
By pressure releasing, elevating lever 1 will be acted on by well head internal pressure and be risen.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
