Description
Technical field
The utility model relates to a kind of well mouth sealing devices simultaneously with shut-in well and open flow function.
Background technique
Currently, many oil recoveries（Gas）Well head is all single homework, needs to install oil recovery after drilling well is complete（Gas）It is all first when tree
Pressure break is needed to shunt in a well, heavy workload is more troublesome.
Summary of the invention
Purpose of the utility model is to solve installations to recover the oil（Gas）Tree will carry out the trouble of kill-job operation, provide one kind
There is the well mouth sealing device of shut-in well and open flow function simultaneously.
The purpose of this utility model solves by the following technical programs：
A kind of well mouth sealing device, it is characterised in that：The well mouth sealing device includes seal valve seat, in seal valve seat
Interior equipped with the through-hole being vertically arranged, it is in horizontally disposed main valve chamber that the lower part of the seal valve seat, which is equipped with, is equipped with master in main valve chamber
Valve, main valve are connected by horizontally disposed main valve stem with main valve handwheel；The top of the seal valve seat is equipped with and lets out for open flow
The side valve of pressure.
The top of the seal valve seat is equipped with the side opening being connected to through-hole, and the other end of side opening is equipped with the side for blocking side opening
Valve.
The side opening is symmetricly set on the two sides of through-hole.
The side valve is symmetricly set on the top two sides of seal valve seat.
The side valve uses manual flat valve.
The utility model has the following advantages compared with prior art：
Well mouth sealing device can be mounted on by the utility model by the setting of well mouth sealing device after drilling well
On well head, recover the oil when needing to install（Gas）When tree, it is only necessary to close the i.e. mountable oil recovery of main valve of well mouth sealing device（Gas）Tree,
After installing, when needing pressure release, the side valve that need to only open well mouth sealing device two sides carries out pressure release；Not
In the case where increasing job step, alleviates labor intensity and facilitate in-site installation oil recovery（Gas）Tree.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the well mouth sealing device of the utility model.
Wherein：1-seal valve seat；2-through-holes；3-main valve chambers；4-main valves；5-main valve stems；6-main valve handwheels；7—
Side valve；8-side openings.
Specific embodiment
The utility model is further described with embodiment with reference to the accompanying drawing.
As shown in Figure 1：A kind of well mouth sealing device, which includes seal valve seat 1, in seal valve seat 1
It is equipped with equipped with the through-hole 2 being vertically arranged and in the lower part of seal valve seat 1 in horizontally disposed main valve chamber 3, main valve chamber 3 is interior to be equipped with master
Valve 4, main valve 4 are connected by horizontally disposed main valve stem 5 with main valve handwheel 6；The top of seal valve seat 1 is equipped with and lets out for open flow
The side valve 7 of pressure is specifically equipped with the side opening 8 being connected to through-hole 2 on the top of seal valve seat 1, and the other end of side opening 8 is equipped with
The side valve 7 and side opening 8 of closure side opening 8 are symmetricly set on the two sides of through-hole 2, therefore side valve 7 is symmetricly set on the top of seal valve seat 1
Two sides.Above-mentioned side valve 7 uses manual flat valve.
Well mouth sealing device can be mounted on by the utility model by the setting of well mouth sealing device after drilling well
On well head, recover the oil when needing to install（Gas）When tree, it is only necessary to close the i.e. mountable oil recovery of main valve 4 of well mouth sealing device（Gas）
Tree；After installing, when needing pressure release, the side valve 7 that need to only open well mouth sealing device two sides carries out pressure release；
In the case where not increasing job step, alleviates labor intensity and facilitate in-site installation oil recovery（Gas）Tree.
Above embodiments are only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
Within the scope of novel protected；The technology that the utility model is not directed to can be realized by the prior art.
