Description
Technical field
The present invention relates to a kind of access type associated gas recovery device, belong to technical field of oil production engineering.
Background technology
At present, oil field at home associated gas recovery process mainly adopts ground recovery technology, and mainly well head constant pressure valve gas collection mixes defeated.Constant pressure valve absorbs heat when air release, Winter protection poor performance, and spool valve seat often cannot use because of frozen block.
Summary of the invention
The object of the present invention is to provide a kind of access type associated gas recovery device, to solve the frozen block problem of spool valve seat, reach the object reclaiming associated gas completely.
Concrete technology contents of the present invention is as follows:
The vertical plug-in mounting of this device valve body is fixed in production tree; Valve body lower end connects lower pressing cap, and middle part barrel is provided with radial steam vent, and upper end is connected with the upper pressing cap of regulating wheel, and the body wall below upper pressing cap is provided with pressure meter; Be provided with valve seat in valve body, valve seat lower end connects lower pressing cap, upper-end contact upper pressing cap; Valve seat top seal is provided with and connects the relief piston of regulating wheel and the pressure transmission side opening of corresponding pressure table, and the sealing of interior step place is provided with pressure transmission piston, and pressure transmission piston is the spring-loaded spring base of adapter sleeve and valve holder successively, and valve holder lower end is provided with valve ball.
This device is located in production tree and works, can by on-the-spot crude oil heat companion heat, thus completely solve air release time heat absorption and winter valve discharging gas under certain pressure frozen block problem.

Fig. 2 is access type associated gas recovery device operating diagram.
Detailed description of the invention
Embodiment:
With reference to Fig. 1 and 2, embodiments of the invention are further illustrated:
This device mainly comprises regulating wheel 1, upper pressing cap 2, relief piston 3, pressure transmission piston 4, spring base 5, steam vent 6, valve holder 7, valve ball 8, valve seat 9, lower pressing cap 10, pressure meter 11 and valve body 12;
The vertical plug-in mounting of valve body 12 is also welded in production tree 13.Valve body 12 lower end internal thread connects lower pressing cap 10, and middle part barrel is provided with radial steam vent 6, and upper external screw thread is connected with the upper pressing cap 2 of regulating wheel 1, and valve body 12 sidewall below upper pressing cap 2 is provided with pressure meter 11.Be provided with valve seat 9 in valve body 12, valve seat 9 lower end internal thread connects lower pressing cap 10, upper-end contact upper pressing cap 2.Valve seat 9 top seal is provided with and connects the relief piston 3 of regulating wheel 1 and the pressure transmission side opening of corresponding pressure table 11, and the sealing of interior step place is provided with pressure transmission piston 4, and pressure transmission piston 4 lower end is the spring-loaded spring base 5 of adapter sleeve and valve holder 7 successively, and valve holder 7 lower end is provided with valve ball 8.
As shown in Figure 2, this device A is inserted in production tree 13 in actual use, and crude oil flows through from the rod radial air vent 6 valve body 12, can reach the effect that companion's heat is antifreeze.This device A will set a force value before working, and namely rotates regulating wheel 1, by relief piston 3 pressure is acted on the hydraulic oil in cylinder, pressure is shown by the pressure meter 11 of peripheral hardware, meanwhile, pressure is delivered on valve ball 8 by pressure transmission piston 4, spring base 5 and valve holder 7, and pressure setting completes.Promote valve ball 8 when gas enters in lower pressing cap 10 and pressure equals setting pressure, open steam vent 6, being passed in production procedure by mixed for associated gas, reclaiming associated gas completely.
