Abstract

The utility model discloses a sealed effectual device is proclaimed oneself to hydraulic pressure well head, include: the body this internal cavity of mutually supporting with oil pipe that is provided with flange at the lower extreme of body the last end screw thread connection of body has the silk of a carrying flange the middle part of body is provided with the oil inlet the inside of body is provided with the sealing member through last skeleton and sending down the fishbone frame, the sealing member sets up at last skeleton under and between the skeleton go up and be provided with first sealing washer between skeleton and lower skeleton and the body respectively it is provided with the second sealing washer to carry between the upper end of silk flange lower extreme and body. The advantage is: sealed effectual, the in -process don't be protected and seal under oil pipe carries, and work efficiency is high, and simple structure uses safe and reliable, guarantees high pressure well's operation safety.

Description

Hydraulic pressure auto Isolator Well Head
Technical field
The utility model relates to a kind of drilling equipment, particularly relates to a kind of hydraulic pressure auto Isolator Well Head.
Background technology
In oil drilling exploitation is produced, there will be a lot of high pressure wells and high pressure oil wells, because down-hole Operating Pressure has more risk, require higher to the sealing performance of equipment and personnel's construction safety.At present, put in process at oil pipe and guarantor's envelope is carried out to well head, affect operating efficiency.
Utility model content
Technical problem to be solved in the utility model is: the hydraulic pressure auto Isolator Well Head providing a kind of good sealing effect.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: hydraulic pressure auto Isolator Well Head, comprise: body, the cavity cooperatively interacted with oil pipe is provided with in described body, the lower end of body is provided with adpting flange, wire-carrying flange is connected with at the threaded upper ends of described body, the middle part of described body is provided with oil-in, in the inside of described body, upper skeleton and lower skeleton are provided with seal, described seal is arranged between upper skeleton and lower skeleton, at described upper skeleton be respectively arranged with the first sealing ring between lower skeleton and body, the second sealing ring is provided with between described wire-carrying flange lower end and the upper end of body.
The utility model has the advantages that: above-mentioned hydraulic pressure auto Isolator Well Head, good sealing effect, put in process at oil pipe and do not protect envelope, operating efficiency is high, and structure is simple, safe and reliable, ensures the job safety of high-pressure well.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model hydraulic pressure auto Isolator Well Head.
In figure: 1, body, 2, cavity, 3, adpting flange, 4, wire-carrying flange, 5, oil-in, 6, upper skeleton, 7, lower skeleton, 8, seal, the 9, first sealing ring, the 10, second sealing ring.
Detailed description of the invention
Particular content of the present utility model is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, hydraulic pressure auto Isolator Well Head, comprise: body 1, the cavity 2 cooperatively interacted with oil pipe is provided with in described body 1, the lower end of body 1 is provided with adpting flange 3, wire-carrying flange 4 is connected with at the threaded upper ends of described body 1, the middle part of described body 1 is provided with oil-in 5, in the inside of described body 1, upper skeleton 6 and lower skeleton 7 are provided with seal 8, described seal 8 is arranged between upper skeleton 6 and lower skeleton 7, at described upper skeleton 6 be respectively arranged with the first sealing ring 9 between lower skeleton 7 and body 1, the second sealing ring 10 is provided with between described wire-carrying flange 4 lower end and the upper end of body 1.
When above-mentioned hydraulic pressure auto Isolator Well Head uses, hydraulic oil fueller is connected with oil-in 5 by oil inlet pipe, and pressure oil promotes seal 8 by oil-in 5 and carries out automatic-sealed to the oil pipe be arranged in cavity 2.
