Abstract
The utility model discloses an annotate sealed first evacuation gas subassembly of fat, reach hydraulic cylinder body and ball valve seat body through threaded connection including sealed first body, the screw hole of offering on screw that ball valve seat body established through its lower extreme outer wall ring and the sealed first body coordinates to be connected, on the hydraulic cylinder body there is rather than the hydraulic pressure mouth that has a perfect understanding through threaded connection the port, this internal piston that is equipped with of hydraulic cylinder, and the steel ball that its piston extended to in the ball valve seat body rather than inside offsets, ball valve seat body is built -in to have steel ball support seat, and steel ball support foot stall portion is fixed with steel ball support spring, and the steel ball has been put to the port on the steel ball support seat, just steel ball and the upper end contact of steel ball support spring, ball valve seat body has seted up the gas vent in one side. Normal close formula non -return valve can long -range liquid console keyboard be driven for the hydraulic cylinder to this subassembly, discharges air in the pressure chamber from the gas vent, accomplishes the recession and falls liquid accuse power, and the non -return valve can reset to normally closed state, realizes annotating the liquid in -process compressed air that drains, guarantees operation safety.
Description
Technical field
This utility model belongs to oil field wireline operation accessory technical field, and in particular to a kind of greasing seal head air-discharging group
Part.
Background technology
During traditional oil field wireline operation, blowout hookup needs to blowout prevention to fill after well head is installed, before driving a well
Interior fluid injection is put, blowout hookup inner air raises internal temperature due to compressing in injection process Central Plains, cable is caused to damage
And gases at high pressure spray generation operation danger from fat mouth is returned.
Utility model content
This utility model solves the deficiencies in the prior art, there is provided a kind of greasing seal head empties pneumatic module, realizes fluid injection
During drain blowout hookup compressed air inside, ensure job safety.
The technical scheme adopted by this utility model is：A kind of greasing seal head empties pneumatic module, including seal head body
And the fluid cylinder body being threaded connection and ball valve seat body, screw thread that the ball valve seat body is set by its lower end outer wall ring and
The screwed hole opened up on seal head body is connected, and the fluid cylinder body upper port is threaded connection the liquid with its insertion
Pressure mouth, the fluid cylinder are originally provided with piston in vivo, and its piston extends to originally internal with which the in vivo steel ball of ball valve seat and offsets, described
Ball valve seat body is built-in with steel ball support base, and the steel ball support base bottom is fixed with steel ball support spring, and the steel ball is supported
Seat upper port is equipped with steel ball, and the steel ball and steel ball support spring upper-end contact, and the ball valve seat body side offers row
QI KOU.
Compared to prior art, this utility model has the advantage that：Remotely can beat hydraulic controlled operation in injection process
Begin to rehearse QI KOU, and gas is discharged blowout hookup, protects cable and excludes potential safety hazard, its simple structure, dependable performance, significantly
Improve working performance and safety.
Description of the drawings
Fig. 1 is this utility model structural representation.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in detail.
A kind of greasing seal head empties pneumatic module, and structure is as shown in figure 1, including seal head body 1 and be threaded connection
Fluid cylinder body 2 and ball valve seat body 3, screw thread and seal head body 1 that the ball valve seat body 3 is set by its lower end outer wall ring
On the screwed hole 10 that opens up be connected, 2 upper port of fluid cylinder body is threaded connection the hydraulic port 9 with its insertion,
Piston 4 is provided with the fluid cylinder body 2, and its piston 4 extends to steel ball 5 internal with which in ball valve seat body 3 and offsets, it is described
Ball valve seat body 3 is built-in with steel ball support base 6, and 6 bottom of steel ball support base is fixed with steel ball support spring 7, the steel ball
6 upper port of support base is equipped with steel ball 5, and the steel ball 5 and 7 upper-end contact of steel ball support spring, 3 side of ball valve seat body
Offer air vent 11.
The component is that fluid cylinder remotely hydraulic control can open normally closed type non-return valve, and pressure chamber air is discharged from air vent,
After the completion of remove hydraulic control power, non-return valve can be reset to normally off, compressed air of draining in realizing injection process, it is ensured that operation
Safety, while improving traditional wireline operation mode, effectively increases the safety of field operation.
Above-described embodiment, simply preferred embodiment of the present utility model, not for limiting enforcement model of the present utility model
Enclose, therefore all equivalent variations done with content described in this utility model claim, all should be included in this utility model right will
Within the scope of asking.
