Abstract
The utility model provides a constant-pressure exhaust recovery device for an oil well casing. The constant-pressure exhaust recovery device is characterized by comprising an anti-freezing constant-pressure exhaust valve, an exhaust hose, an exhaust tee and a pressure gauge. The anti-freezing constant-pressure exhaust valve is connected with a port A of the exhaust tee, a port B of the exhaust tee is connected with the pressure gauge, and the anti-freezing constant-pressure exhaust valve has the function of regulating pressure. The constant-pressure exhaust recovery device for the oil well casing has the advantages that special structure allows the device to increase exhaust temperature of the casing by well fluid produced by an oil well, freeze-plugging is prevented, and the anti-freezing constant-pressure exhaust valve can be prevented from freeze-plugging; and a pressure regulating rod and a constant pressure rod with a through hole are disposed in the anti-freezing constant-pressure exhaust valve, outside accurate constant pressure can be achieved, and convenience is provided for pressure regulation.
Description
Technical field
The utility model relates to the oil production equipment field, relates in particular to a kind of level pressure air-bleed retracting device.
Background technology
At present, in the mechanical oil production model no matter be sucker rod pumping or electric submersible pumping, for preventing gas to the impact of oil well pump, all adopt carry out in the shaft bottom Oil-gas Separation and respectively the method for extraction recover the oil.Well liquid enters in the oil extraction pump, discharges from oil pipe top, and gas, is finished oil gas again and again converged by self pressure discharge from sleeve pipe in the well head production tree, together enter the individual well export pipeline.Decline to a great extent because swelling heat absorption can cause temperature from the gas of sleeve pipe output, cause easily the valve discharging gas under certain pressure generation frozen block phenomenon that is installed on the oil pipe, affect its normal use.Existing valve discharging gas under certain pressure does not have regulatory function, uses very inconvenience.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of oil well casing level pressure air-bleed retracting device, it is characterized in that comprising antifreezing type valve discharging gas under certain pressure, air exhaust hose, venting threeway and pressure meter, the antifreezing type valve discharging gas under certain pressure is connected by the port A of air exhaust hose with the venting threeway, the port B of venting threeway is connected with pressure meter, and described antifreezing type valve discharging gas under certain pressure has pressure adjusting function.
Described antifreezing type valve discharging gas under certain pressure comprises valve body, pore, spring, valve ball, valve seat, benefit core, level pressure bar and pressure adjusting lever, valve ball one end is connected with spring, the other end and valve seat are adjacent to, valve seat is connected with level pressure bar one end by mending core, the level pressure bar other end is connected with pressure adjusting lever, be positioned at one of pore on the valve body and rectify level pressure bar side, the other end is over against air exhaust hose, and described level pressure bar side is provided with through hole.
Described air exhaust hose adopts the multi-layer braided sebific duct of steel wire.
The beneficial effects of the utility model are: distinctive structure prevents the frozen block phenomenon, as long as oil well liquid-producing just can prevent antifreezing type valve discharging gas under certain pressure frozen block so that this device can utilize the well liquid of oil well output to improve the sleeve pipe delivery temperature; Pressure adjusting lever is installed and with the level pressure bar of through hole in the antifreezing type valve discharging gas under certain pressure, can realize outside accurately level pressure, for pressure regulation provides convenience, simultaneously so that the antifreezing type valve discharging gas under certain pressure has cutoff function and check function, when clockwise direction rotated to the end with pressure adjusting lever, the antifreezing type valve discharging gas under certain pressure had the function of stop valve, when level pressure value during greater than 0.01MPa, function with flap valve prevents that medium from flowing backwards.That air exhaust hose adopts is high pressure resistant, the multi-layer braided sebific duct of steel wire of oil resistant, the corrosion of anti-natural gas, and the gas that fully takes into account in the oil pipeline has corrosive situation, has prolonged the application life of this device.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Among the figure, the threeway of exitting of 1-air exhaust hose, 2-, the 3-pressure meter, the 4-valve body, the 5-pore, the 6-spring, the 7-valve ball, the 8-valve seat, 9-mends core, 10-level pressure bar, 11-pressure adjusting lever, 12-port A, 13-port B, 14-oil pipe.
As shown in Figure 1, antifreezing type valve discharging gas under certain pressure one end is connected with oil pipe 14, the other end is connected by the port A12 of air exhaust hose 1 with venting threeway 2, the port B13 of venting threeway 2 is connected with pressure meter 3, the antifreezing type valve discharging gas under certain pressure comprises valve body 4, pore 5, spring 6, valve ball 7, valve seat 8, mend core 9, level pressure bar 10 and pressure adjusting lever 11, valve ball 7 one ends are connected with spring 6, the other end and valve seat 8 are adjacent to, valve seat 8 is connected with level pressure bar 10 1 ends by mending core 9, level pressure bar 10 other ends are connected with pressure adjusting lever 11, the level pressure bar offers some through holes on 10 sides, be positioned at one of pore 5 on the valve body 4 and rectify level pressure bar 10 sides, the other end is over against air exhaust hose 1.
Bump off a well, close each valve of petroleum pipeline, the port C of the venting threeway 2 of this device is communicated with sleeve pipe, the antifreezing type valve discharging gas under certain pressure is communicated with oil pipe; Open each valve of petroleum pipeline, rotation pressure adjusting rod 11, the force value that makes pressure meter 3 is the level pressure value; Gas enters this device from sleeve pipe, enters oil pipe by venting threeway 2, air exhaust hose 1 and antifreezing type valve discharging gas under certain pressure successively.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
