Abstract
The utility model discloses a built-in one-way valve of a valve or a pipeline, which is applied to liquid conveying pipelines or valves and arranged in the valve or pipeline, and can effectively prevent the loss caused by the leakage and pouring of the fluid in the valve or pipeline, e.g. leakage of crude oil or pouring of well liquid. The built-in one-way valve comprises a casing and a valve core, wherein the valve core is arranged in the casing; the inner cavity of the outlet end of the casing is provided with a valve core travel positioning ring, and the outer circle of the outlet end of the casing is provided with a locking and sealing mechanism. The utility model has the advantages of simple structure, small volume, light weight, convenient installation and removal, low cost, good concealed and antitheft property, difficult damage and little liquid resistance, and can be used in various liquid conveying pipelines and valves. If used for the wellhead of the oil exploration well of the petroleum industry, the built-in one-way valve can prevent the phenomena that the pollution is caused by the leakage of the wellhead; the crude oil is stolen by artificial damage, and also can prevent the liquid pouring caused by failure of oil pumps, leakage of oil pipes and the like, thereby avoiding the liquid loss of the oil well.
Description
Technical field
The utility model relates to the check device of liquid conducting pipes or valve, the built-in one-way valve of particularly a kind of valve or pipeline, this device is installed in valve or pipeline, can effectively prevent the escape of liquid in valve or the pipeline or pour in down a chimney the loss that brings, pour in down a chimney the loss that causes as crude oil leakage and well liquid.
Background technique
At present in the fluid pipeline in oil field was carried, single current check device kind was more, and commonly used have cartridge type one-way valve DFF-250 type, H44H series and H41H series, and certain using scope is arranged, but relatively heavier, weight is big, and effective date is short.Wherein DFF-250 type one-way valve, H44H series and the two-way manufacture cost height of setting upright one-way valve series.The unfavorable popularization of one-way valve technical sophistication that has is as Lift check valve.The one-way valve broad applicability that has is low, and is bigger to the pipeline liquid resistance, needs breakout pressure, as the two-way one-way valve etc. of setting upright.General one-way valve mainly adopts flange to connect or is welded to connect, and it is long that complicated holding time is installed.Except that above-mentioned defective, one-way valve also ubiquity easily goes to pot, the defective of theftproof performance difference.These defectives all have adverse effect to produced on-site.
Summary of the invention
The purpose of this utility model provides the built-in one-way valve of a kind of valve or pipeline, the defective that overcome existing one-way valve complex structure, heaviness, easily goes to pot etc., make that it is simple in structure, with low cost, theftproof performance is good, resistance convection cell is less, increase economic efficiency.
The present technique solution can reach above-mentioned purpose: the built-in one-way valve of a kind of valve or pipeline comprises housing and spool, and spool is installed in the housing, in the outlet end inner chamber of housing the spool stroke positioning ring is housed, and the outlet end cylindrical is equipped with lock sealing mechanism.
The beneficial effects of the utility model are: this apparatus structure is simple, small and exquisite in light weight, installs and convenient to remove, and cost is low, and is hidden, theftproof performance good, and is survivable, and liquid resistance is little, can use in various liquid conducting pipes and valve.As be used for the oil recovery well well head of petroleum industry, can stop well head from the source and leak the phenomenon that crude oil is stolen in the pollution that causes and artificial destruction.Simultaneously can prevent to pour in down a chimney, avoid the loss of oil well liquid measure, have tangible economic benefit because of the liquid that factors such as oil well pump inefficacy, oil pipe severe leakage cause.
Description of drawings

The A-A of Fig. 2 the utility model spool is to view.
Embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to Fig. 1, the built-in one-way valve of a kind of valve or pipeline comprises housing 1 and spool 2, spool 2 is installed in the housing 1, in the outlet end inner chamber of housing 1 spool stroke positioning ring 3 is housed, and the outlet end cylindrical is equipped with lock sealing mechanism.Referring to Fig. 1 and Fig. 2, spool 2 is goblets, and cup end cylindrical is a cone structure, and the cup cylindrical is provided with guiding gutter, and the cup cylindrical cooperates with the interior circle of housing 1.Guiding gutter on the spool 2 is provided with two at least.The stroke of spool 2 relies on spool stroke positioning ring 3 to regulate.The entrance point of housing 1 is a conical internal cavity, cooperates with the cup end cylindrical of spool 2, prevents that the fluid in valve or the pipeline from pouring in down a chimney.Lock sealing mechanism comprises seal ring 6, spacer ring 4 and retaining ring 5, and spacer ring 4 is installed between the seal ring 6, and retaining ring 5 is installed in the outside of outside seal ring 6.At least be provided with two seals circle 6 in the lock sealing mechanism.The external diameter of housing 1 conforms to the internal diameter of installation carrier, as the internal diameter of valve or pipeline.
During use, load the housing 1 of this device in the valve cavity between conventional valve flanges and flashboard or the correct position in the pipeline, note the feed liquor and the fluid direction of this device, utilize the fastening good retaining ring 5 of special spanner, seal ring 6 is expanded, this built-in one-way valve tightly is embedded in valve or the pipeline.Utilize the stroke of the outer screw thread setting spool 2 of spool stroke positioning ring 3.Normally connecting flow process can move, and pours in down a chimney as liquid, enters the liquid in spool 2 goblets, will be pushed into spool 2 in the conical internal cavity of housing 1 entrance point, plays the effect that liquid can only one-way flow that makes.
