Abstract
The utility model provides a novel union formula single current valve, includes body, disk seat and case, and the body inner chamber is cylindric, and the disk seat is installed through the step cooperation and is compressed tightly in the body inner chamber and through the gland, the gland passes through union relatively fixed with the body, the axial one end of disk seat is equipped with valve opening, other end erection bracing seat, and the central authorities of supporting seat are equipped with the sliding sleeve, the periphery is equipped with a plurality of through -holes, the case includes interconnect's sealed head and slide bar, sealed head with the sealed cooperation of valve opening, slide bar are installed in the sliding sleeve and rather than constituting sliding fit, be equipped with reset spring between case and the supporting seat. The utility model discloses a case is fixed that this is internal at the single current valve to form that the union is connected, when single current valve case is dismantled to needs, only need beat the union nut, and dismantlement that just can be quick goes out single current valve case, and new case of overall change has solved that present structure single current valve is dismantled and the technical problem of installation complicacy for the dismantlement and the installation convenient and fast of single current valve.
Description
Technical field
The utility model relates to oil and gas development apparatus field, is specially the Novel union formula one-way valve in a kind of oil filed pipeline.
Background technique
In oil filed pipeline, one-way valve is absolutely necessary device, can effectively prevent liquid from flowing backwards.Normally used one-way valve has rotary-open type and rise-fall type.Owing to comprising plurality of impurities in crude oil, impurity can stick to one-way valve inside, causes one-way valve cisco unity malfunction, needs one-way valve to disassemble to check or clear up.Existing one-way valve easily causes leakage, and removes and installs process complexity, causes maintenance engineering workload large.
Model utility content
The object of the invention is to overcome the above-mentioned problems in the prior art, provide a kind of dismountable union formula one-way valve, one solves the defect that existing one-way valve removes and installs process complexity, the defect that the existing one-way valve of its two solution is easily missed.
The technical solution of the utility model: comprise body, valve seat and spool, it is characterized in that: described chamber body is cylindric, described valve seat is coordinated by step and to be arranged in chamber body and to be compressed by gland; Described gland is relative fixing by union with body; One end of described valve seat axis is provided with valve opening, the other end installs supporting base, and the central authorities of described supporting base are provided with sliding sleeve, periphery is provided with multiple through hole; Described spool comprise interconnective sealing head and slide bar, described sealing head and described valve opening are sealed and matched, and described slide bar to be arranged in sliding sleeve and to be slidably matched with its formation; Returnning spring is provided with between described spool and supporting base.
Such scheme more preferably,
Preferably, described sealing head surface is provided with vulcanized rubber, and described valve opening surface overlaying Ni60, valve seat spool resistance to erosion sealing effect is better.
Preferably, described supporting base is arranged in valve seat by screw-thread fit.
Preferably, described valve seat be provided with at least with the circumferential surface of contact of body together with seal ring.
Preferably, described gland is coordinated by step and is arranged on outside chamber body, and gland interior edge face and valve seat exterior edge face against.
Preferably, described gland be provided with at least with the circumferential surface of contact of body together with seal ring.
Preferably, described seal ring is O type circle, and quantity is twice.
Spool is fixed in one-way valve body by the form that the present invention is connected by union, when needs dismounting one-way valve spool, only need to knock union nut, just can remove one-way valve spool fast, the spool that integral replacing one is new, solve the dismounting of existing structure one-way valve and the technical problem of installation process complexity, make the dismounting of one-way valve and installation process convenient and swift.Meanwhile, spool is provided with vulcanized rubber, and is provided with O type circle between body and valve seat, makes this one-way valve have good sealability.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
In figure: wherein: 1-body; 2-valve seat; 3-vulcanized rubber; 4-spool; 5-spring; 6-the one O type circle; 7-supporting base; 8-the 2nd O type circle; 9-union nut; 10-union back-up ring; 11-circlip for shaft; 12-gland.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1, a kind of Novel union formula one-way valve, is made up of body 1, valve seat 2, spool 4, spring 5, supporting base 7, gland 12, union nut 9 etc.Body 1 inner chamber is cylindric, and valve seat 2 is placed in chamber body, uses the gap between O RunddichtringO 6 seal valve seat 2 and body 1, with spool 4 surface of contact built-up welding Ni60 on valve seat 2; Spool 4 is placed in valve seat 2 chamber, and the vulcanized rubber 3 on spool 4 sealing surface utilizes spring 5 extruding that itself and valve seat 2 are sealed, and spring 5 is placed on supporting base 7; When spool 4 pressure is greater than spring 5 extruding force, camber of spring, fluid will pass through valve seat 2, supporting base 7 and gland 12 successively; Supporting base 7 is coordinated with valve seat 2 by screw thread, and on supporting base, 7 have through hole, and fluid is passed through; With gland 12, valve seat 2 is fixed in body 1, seals with the 2nd O type circle 8 between gland 12 and body 1, be then fixed by union nut 9.When one-way valve needs cleaning or changes spool 4, only need knock union nut 9, just one-way valve can be taken apart.
For those skilled in the art, under the prerequisite not departing from the utility model principle, likely to concrete size, or partial structurtes make some improvements and modifications, and these improvements and modifications also should be considered as protection domain of the present utility model.
