Abstract
An adjustable constant pressure exhaust device comprises a protecting cover, an adjusting rod, a spiral spring, a sealing ball, a valve seat, a base, an air inlet pipe and an air outlet pipe, and is characterized in that theprotecting cover is in threaded connection with the upper part of a body; the lower part of the body is in threaded connection with the upper part of the valve seat; the lower part of the valve seat is in threaded connection with the base; the adjusting rod isin threaded connection with a threaded hole in the centerpart of the body; the sealed ball is arranged on the valve seat; the spiral spring is arranged between the adjusting rod and the valve seat; the air inlet pipe is arranged in the middle of the periphery of the valve seat; the air outlet pipe is arranged on the periphery of the upper part of the body. The adjustable constant pressure exhaust devicehas the advantages that sleeve gas can be recycled to an oil collecting pipeline in constant pressure according to the pressure in the oil collecting pipeline, so that the purposes of discharging sleeve gas and recycling sleeve gas can be achieved; not only is normal production of an oil well ensured, but also energy is not wasted, and environment cannot be polluted; the exhaust device is simple in structure, practical and convenient.
Description
Technical field
The utility model relates to a kind of adjustable constant pressure exhaust device, solves casing of oil-pumping well gas and supply air line and the problem for the exhaust of steam pipework level pressure steam supply.
Background technology
The oil-gas ratio that the rod-pumped well in oil field has is at present higher, and casing pressure is larger, causes producing fluid level lower, directly affects oily well yield, must often put casing gas guarantee oil well and normally produce.Some supply air line hypertonia, burner can not burn, and the level pressure guarantee burner that must reduce pressure is normally worked.Some is for steam pipework hypertonia, and user's family excess Temperature also needs the level pressure steam supply that reduces pressure.All need an adjustable constant pressure exhaust device, the equipment of this type is all undesirable at present, and the especially casing gas of rod-pumped well discharge, is all to enter atmosphere, can not reclaim contaminated environment.
Summary of the invention
Order rhythm of the present utility model is to provide a kind of adjustable constant pressure exhaust device, overcomes the defect that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises protecting cover, adjusting rod, helical spring, ball sealer, valve seat, base, air inlet pipe and escape pipe, it is characterized in that protecting cover is connected with body top screw thread, body bottom is connected with valve seat top screw thread, and valve seat bottom is connected with whorl of base; Adjusting rod is connected with the screwed hole screw thread of central part on body, and ball sealer is sitting on valve seat, between adjusting rod and valve seat, is provided with helical spring, is provided with an air inlet pipe at the periphery middle part of valve seat, is provided with an escape pipe in the upper periphery of body.
Adjusting rod is made as cylindrical, and top is provided with adjustment cap, and bottom is provided with pressing plate, and middle part is provided with male thread.
Body is made as cylindrical, and top is provided with male thread, and bottom is provided with box thread, in male thread section upper axial, is provided with gas pressure relief slot one.
Valve seat is made as cylindrical, and top is provided with male thread, and central upper portion is provided with conical seat, and bottom is provided with box thread.
The utility model has the advantages that; Can casing gas constant-pressure be recovered in gathering line according to the pressure in gathering line, not waste energy, free from environmental pollution.In the time that the set pressure relief groove in body male thread section top can prevent from unloading protecting cover, leakage pressure is got protecting cover to hurt sb.'s feelings, simple and practical convenience.
Brief description of the drawings
Accompanying drawing 1-structural representation of the present utility model;
1-protecting cover, 2-adjusting rod, 3-escape pipe, 4-helical spring, 5-ball sealer, 6-valve seat, 7-base, 8-air inlet pipe in figure;
Detailed description of the invention
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model comprises protecting cover 1, adjusting rod 2, helical spring 4, ball sealer 5, valve seat 6, base 7, air inlet pipe 8 and escape pipe 3, it is characterized in that protecting cover is connected with body top screw thread, body bottom is connected with valve seat top screw thread, and valve seat bottom is connected with whorl of base; Adjusting rod is connected with the screwed hole screw thread of central part on body, and ball sealer is sitting on valve seat, between adjusting rod and valve seat, is provided with helical spring, is provided with an air inlet pipe at the periphery middle part of valve seat, is provided with an escape pipe in the upper periphery of body.Regulate level pressure according to the pressure in oil well gathering line by adjusting rod, pressure is transferred to the pressure a little more than gathering line.When casing gas pressure is during higher than the pressure of gathering line, casing gas will back down ball sealer, and casing gas enters gathering line by escape pipe, reaches the object of bar casing tube gas and recovery of casing gas.Both ensured that oil well normally produced, do not wasted energy again, free from environmental pollution.
