Flat gate valve, the 4th interface also concatenate the 5th and the 6th two high temperature height by the O-shaped sealing ring sealing of metal, combination sealing filler
Kill-job mouth flat gate valve；Equipped with the second four-way, the first interface of the second four-way connects the of the 6th high temperature and pressure well head flat gate valve
Two ends；The second interface and third interface of second four-way are separately connected the 7th and the 8th high temperature and pressure well head flat gate valve, and the 7th
It is separately connected high temperature and pressure adjustable balancing formula throttle valve with the 8th high temperature and pressure well head flat gate valve, the 4th of the second four-way connects
Mouth the 9th high temperature and pressure well head flat gate valve of connection and bull plug, bull plug connector is for connecting oil well mouth.
The first interface of 4th interface of tubing head four-way and the second four-way point-blank, the 4th of tubing head four-way the
What is connected between interface and the first interface of the second four-way is that the O-shaped sealing ring of metal seals, combination sealing filler also concatenates the 5th
With the 6th two high temperature and pressure well head flat gate valve.
The course of work of the utility model: when two high temperature and pressure well head flat gate valves in figure on the right of device lowest part are beaten
It opens, high steam is injected, when to be recovered the oil top high temperature and pressure well head flat gate valve and high temperature and pressure adjustable balancing
Formula throttle valve is opened, if all valves are closed, closes entire channel, is terminated the steam injection of high temperature and pressure and is recovered the oil.
The utility model is using the O-shaped sealing ring sealing of metal.
The utility model has the advantages that the utility model uses the O-shaped sealing ring of metal, guarantee the steam under working condition at high temperature under high pressure
The sealed reliable of mouth；High temperature and pressure well head flat plate gate valve gate plate uses slab construction, and no flow resistance, can both have been recovered the oil can also be with
Inject high temperature and high pressure steam.Using high temperature and pressure adjustable throttle valve, spool uses the adjustable type structure with balancing device, guarantees
It adjusts accurate and reliable.4th interface of tubing head four-way and the first interface of the second four-way are in straight line and high temperature and pressure warm
Shut-off valve is adopted using single flow structure, flow resistance is small, and flap uses damping structure, guarantees sealed reliable.High temperature and pressure well head is flat
The sealing of plate flashboard for sluice valve uses novel enhanced soft graphite special construction, and the breakable problem of the soft graphite of solving over is protected
Demonstrate,prove sealing performance under the conditions of high temperature and high pressure condition.Filler uses composite structure, guarantees the reliability of sealing.Using not of the same race
The carbide reactor welding technology of class keeps sealing surface corrosion-resistant, and impact resistance guarantees the service life of device.The utility model is for adopting
It with the integrated wellhead for production in oil recovery field and oil field out, saves big quantity space, reduce investment outlay, convenient for management.
