Abstract
The utility model be related to one kind exempt from kill-job exempt from unload Christmas tree wellhead blowout preventer.Mainly solve the problem of tedious process is changed in existing sealer for mouth of oil extraction well maintenance, labor intensity is big.It is characterized in that：The centerbody（3）The upper left and right sides is connected to horizontal valve（2）, centerbody（3）Connector and horizontal valve（2）Between escribe valve（1）, and escribe valve（1）With horizontal valve（2）Respectively with centerbody（3）Inside is communicated.This exempt from kill-job exempt from unloading Christmas tree wellhead blowout preventer is realized in seal failure need not well-flushing kill-job and the i.e. replaceable seal member of oil pumping machine unloading, eliminate substantial amounts of manpower and materials and eliminate and produce the adverse effect brought so that repair and replacement are simple and convenient.
Description
Technical field
The utility model is related to oilfield, and specifically one kind exempts from kill-job and exempts from unloading Christmas tree wellhead blowout preventer.
Background technology
The production tree that Christmas tree wellhead blowout preventer is used in the daily production of producing well, is changing packing for sealing polish rod and disk
Closed during root box, to obstruct the band press liquid in oil pipe.Christmas tree wellhead blowout preventer is in routine use consumption and long-time oil
Under air water immersion corrosion, damage and cause seal failure, it is necessary to carry out maintenance replacing.Changing blowout preventer at present needs well-flushing pressure
Well, shed after oil pumper load and to wear replacing from polished rod, tedious process, input manpower and materials are more, labor intensity is larger.
The content of the invention
In order to overcome the shortcomings of that existing sealer for mouth of oil extraction well maintenance replacing tedious process, labor intensity are big, this practicality
New offer one kind exempts from kill-job and exempts to unload Christmas tree wellhead blowout preventer, and this is exempted from kill-job and exempts from unloading Christmas tree wellhead blowout preventer in sealing
Realized during failure need not well-flushing kill-job and oil pumping machine unloading be replaceable seal member, eliminate substantial amounts of manpower and materials and elimination
The adverse effect brought in production so that repair and replacement are simple and convenient.
The technical solution of the utility model is：One kind exempts from kill-job and exempts to unload Christmas tree wellhead blowout preventer, including centerbody, in
Heart body upper and lower ends connect the left and right sides on packing box and wellhead tree tree ring flange, the centerbody and are connected to water respectively
Flat valve door, escribes valve between the connector of centerbody and horizontal valve, and escribe valve and horizontal valve respectively with center
Internal portion is communicated.
It is respectively arranged on the left side and the right side on the centerbody on horizontal valve connecting seat, horizontal valve connecting seat and is connected with level
Valve, escribes valve connecting seat between the connector of centerbody and horizontal valve, escribe to be connected with valve connecting seat and escribe
Valve.
The horizontal valve is connected by horizontal valve housing with centerbody, and horizontal valve housing is internally connected with level silk
Thick stick, horizontal screw lead the inner is connected with horizontal flashboard.
The valve that escribes is gate valve.
It is described to escribe valve plate and be connected by escribing valve housing with centerbody, escribe valve housing and be internally connected with leading screw,
Leading screw end is connected with flashboard.
The utility model has the advantages that：Due to taking such scheme, pass through escribing for being connected on centerbody
Valve and horizontal valve carry out mutually switch switching：The horizontal valve of standard-sized sheet, which is closed, during replacing horizontal valve escribes valve, changes other
Standard-sized sheet escribes the horizontal valve of valve closing during cutting valve so that when changing, maintenance escribing valve or horizontal valve, can make
Pit shaft is sealed, and prevents liquid leakage in pit shaft.Compared with existing replacing Wellhead packer, change the side that maintenance is changed completely
Formula, eliminates vehicle input by cementing truck well-flushing, oil consumption, water consume, while avoiding the ground lamination production that well-flushing kill-job is brought
（Oil well output is reduced）；Eliminate check card sub- unloading, equipment of oil pumper to wear and fasten big torsion spiral shell button with loose unloading, reduce work
Process, significantly reduces labor intensity.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Fig. 1 to Fig. 4, one kind exempts from kill-job and exempts to unload in Christmas tree wellhead blowout preventer, including centerbody 3, centerbody 3
Portion is four-way, and the upper and lower ends of centerbody 3 connect packing box and wellhead tree tree ring flange respectively, and the left and right sides is connected to water
Flat valve door 2, and the upper and lower ends of centerbody 3 are respectively upper binding head 33 and lower union joint 34, one of connector both sides
Valve 1 is escribed between horizontal valve 2.Valve 1 and the horizontal valve 2 of escribing is communicated with inside centerbody 3 respectively.To make
Horizontal valve 2 is respectively arranged on the left side and the right side horizontal valve connecting seat 32, water with escribing on the convenient fixation of valve 1, the centerbody 3
Horizontal valve 2 is connected with flat valve door connecting seat 32,3 liang of upper lateral parts of centerbody escribe valve provided with valve connecting seat 31 is escribed
It is connected with connecting seat 31 and escribes valve 1.
The horizontal valve 2 is connected by horizontal valve housing 22 with centerbody 3, and horizontal valve housing 22 is internally connected with
Horizontal screw lead 21, the inner of horizontal screw lead 21 is connected with horizontal flashboard 23, and horizontal flashboard 23 can be under the drive of horizontal screw lead 21
In move or be displaced outwardly.When movement makes horizontal 2 Close All of valve to horizontal flashboard 23 inwards, horizontal valve 2 and centerbody 3
And internal polished rod is collectively forming seal combination, band press liquid in pit shaft can be closed；When horizontal flashboard 23 is moved outwardly to close
When right position is put, the inner passage of centerbody 3 is opened, the valve passage that escribes on top closed, liquid enters other in barrier pit shaft
Cutting valve 1, carries out replacing and escribes the No leakage of valve 1.
The valve 1 that escribes is gate valve, or other can realize the valve of identical function.Illustrate below by taking gate valve as an example
Escribe the structure and function of valve 1, it is described to escribe valve plate 1 and be connected by escribing valve housing 11 with centerbody 3, escribe valve shell
