Abstract

The utility model relates to a sleeve pipe pressure control device used for oil-field production, wherein, a valve seat (1), a valve cover (4), a valve rod (5), sealing materials (8), a pressing cover (6) and a pressing cap are assembled into inner cavity seal. A pressure spring (3) in the cavity is sheathed on a valve core (2), the valve rod (5) is pressed on the pressure spring (3), and the pressure of the sleeve pipe can be kept with a stable value by regulating the top and the bottom positions of the valve rod (5). The utility model has the advantages of simple structure and convenient operation.

Description

Automatic pressure regulator
The utility model relates to field produces casing pressure control gear.
In the prior art, control sleeve in oil field pressure is to finish by the manual control valve of well head, there is following shortcoming in this device: 1, need frequent adjusting control valve during pilot pressure, 2, pilot pressure shakiness, it is bigger to fluctuate, and 3, because of controlling improper or casing pressure is too high or too low all can influence crude output.
The purpose of this utility model is the shortcoming that overcomes manual control casing pressure shakiness, for the casing pressure of control reasonably stability is carried a kind of casing pressure automatic regulating valve of control.
The utility model comprises valve seat (1), spool (2) and bonnet (4), it is characterized in that in the inner chamber of valve seat (1) spool (2) being housed, there is conical boss (11) lower end of spool (2), stage clip (3) is sleeved on the spool (2), valve rod (5) is pressed on the stage clip (3), bonnet (4) is fixedlyed connected with valve seat (1), between bonnet (4) and the valve rod (5) by being threaded, and sealing material (8) is housed between the body of rod of valve rod (5) and bonnet, gland (6) is pressed on the sealing material (8), pressure cap (7) is fixedlyed connected with bonnet (4), between bonnet (4) and the valve seat (1) seal ring (10) is arranged.
Fig. 1 is the utility model erection drawing;
Fig. 2 is the utility model gland structure figure.
Below in conjunction with drawings and Examples the utility model is described in further detail:
As shown in the figure, the lower end of the utility model valve seat (1) links to each other with sleeve pipe, the outlet of valve seat (1) side with put pressure pipe (9) and fixedly connected, form airtight automatic deflation.Spool (2) is contained in the inner chamber of valve seat (1), there is conical boss (11) lower end, stage clip (3) is sleeved on the spool (2), fixedly connected by screw thread between bonnet (4) and the valve seat (1), valve rod (5) is pressed on the stage clip (3), adopts between the bottom of valve rod (5) and the inwall of bonnet (4) to be threaded, and between bonnet (4) and valve rod (5) sealing material (8) is housed, gland (6) compresses sealing material (8), and pressure cap (7) is screwed on the bonnet (4).Bonnet (4), valve rod (5), gland (6), pressure cap (7) and sealing material (8) form bore seal.In order further to guarantee sealing, suit seal ring (10) between valve seat (1) and bonnet (4).Working principle of the present utility model is: according to the height of pumping well control casing pressure, the upper-lower position of regulating valve stem (5), make stage clip (3) be subjected in various degree pressure, thereby increase or reduce the gap of spool (2) and valve seat (1) sealing surface, by the sleeve pipe gas of releasing, make casing pressure keep a stationary value.
The utility model has the advantages that: the size according to controlled pressure is transferred automatically Press, pressure oscillation is little, is conducive to oil well production, and is simple in structure, is easy to behaviour Do.

Claims (2)

1. automatic pressure regulator that field produces is used, comprise valve seat (1), spool (2) and bonnet (4), it is characterized in that in the inner chamber of valve seat (1) spool (2) being housed, spool (2) lower end is conical boss (11), stage clip (3) is sleeved on the spool (2), valve rod (5) is pressed on the stage clip (3), bonnet (4) is fixedlyed connected with valve seat (1), bonnet (4) adopts with valve rod (5) and is threaded, and between bonnet (4) and the valve rod (5) sealing material (8) is housed, and gland (6) is pressed on the sealing material (8), pressure cap (7) is fixed on the upper end of bonnet (4), between bonnet (4) and the valve seat (1) seal ring (10) is arranged.
2, automatic pressure regulator according to claim 1 is characterized in that adopting between bonnet (4) and the valve seat (1) being threaded.
