Abstract

A check valve with a replaceable valve core comprises a shell body, a liner, a valve core, a spring, sealing rings, a stud bolt, a pressing cover, a pressing block, a nut and sealing gaskets. The shell body of the check valve with the replaceable valve core is in a bucket shape, the lower portion of the shell body is provided with an inlet, the middle of the shell body is provided with an outlet, and the periphery of top of the shell body is provided with more than four threaded blind holes. Two ends of the liner are respectively provided with two sealing rings, the liner is installed inside the sell body, and the sealing gaskets are respectively arranged on the upper side and the lower side of the liner. A horn mouth corresponding to the inlet and a round hole corresponding to the outlet are arranged on the liner, the valve core, the spring, and the pressing block are arranged inside the liner in sequence from bottom to top, and the pressing cover is connected with the shell body through the stud bolt and the nut to press tightly the pressing block. The check valve with the replaceable valve core is simple in structure, convenient to install and easy to replace. When the valve core of the check valve and other parts are corroded and damaged, and the check valve can not be closed tightly, the pressing cover is detached, a new valve core and other parts are installed, and replacement is finished. The check valve with the replaceable valve core is safe, reliable, saving in cost, and capable of greatly shortening the time of pump stopping, improving the operation efficiency of equipment, and guaranteeing the normal water injection of oil fields.

Description

Replaceable spool one-way valve
Technical field
the utility model relates to high oil field water injection pump discharge pipeline accessory, particularly is a kind of replaceable spool one-way valve.
Background technique
The one-way valve of oil-field flooding station application at present is the disposable production procedure that is welded to; In use spool can be washed away, corrode by sewage for a long time; Cause one-way valve to fit badly, influence the normal water filling in oil field, change if desired; Just must whole one-way valve be cut down from pipeline, just can return to normal production after changing one-way valve again through gas cutting.One-way valve termination of pumping length consuming time is changed in cutting, workload is big, and worker's labor intensity is big, waste material not only, and influence the normal water filling in oil field.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to existing technology, designs a kind of replaceable spool one-way valve.
The utility model is realized by following technical proposals:
the utility model comprises: housing, lining, spool, spring, seal ring, stud bolt, gland, briquetting, nut, sealing gasket.Its replaceable spool single current valve housing is a round barrel shape, and the bottom is provided with import, and the middle part is provided with outlet, is provided with four above tapped blind holes around the top; The lining two ends respectively are provided with the two seals circle; Be installed in the housing, the upper and lower sealing gasket that is lined with respectively, lining and import are provided with horn mouth relatively; Be provided with circular hole relatively with outlet; Spool, spring, briquetting are contained in the lining from bottom to top successively, and gland is connected with housing through stud bolt, nut, and briquetting is compressed.
Spool lower end in above-mentioned replaceable spool one-way valve is that cone structure cooperates with the lining horn mouth, is provided with four above flowing holes around the spool, and the upper end of spool is provided with spring seat.
Briquetting in above-mentioned replaceable spool one-way valve is an one-level step circle column structure, and the center is provided with a tapped blind hole.
The beneficial effect of the utility model is: simple in structure, easy for installation, be easy to change; After one-way valve spool and the damage of other component corrosion, when fitting badly, only need dismantle gland; Upgrade spool and other parts and get final product, safe and reliable, practice thrift cost; Shorten the termination of pumping time greatly, improve equipment operating efficiency, guarantee the normal water filling in oil field.
Description of drawings
accompanying drawing is that the utility model master looks the complete section structural representation.
In accompanying drawing, 1. housing, 2. lining, 3. spool, 4. spring, 5. seal ring, 6. stud bolt, 7. gland, 8. briquetting, 9. nut, 10,11. sealing gaskets; A. import, B. outlet, C. tapped blind hole, D. flowing hole.
Embodiment
Below in conjunction with accompanying drawing further elaboration is done in the enforcement of the utility model:
the utility model is by housing 1, lining 2, spool 3, spring 4, seal ring 5, stud bolt 6, gland 7, briquetting 8, nut 9, sealing gasket 10,11; Its replaceable spool single current valve housing 1 is a round barrel shape, and the bottom is provided with import A, and the middle part is provided with outlet B, is provided with four above tapped blind holes around the top; Lining 2 two ends respectively are provided with two seals circle 5; Be installed in the housing 1, the upper and lower sealing gasket 10,11 that is lined with respectively, lining 2 is provided with horn mouth relatively with import A; B is provided with circular hole relatively with outlet; Spool 3, spring 4, briquetting 8 are contained in the lining 2 from bottom to top successively, and gland 7 is connected with housing 1 through stud bolt 6, nut 9, and briquetting 8 is compressed.When one-way valve corrodes when inoperative, dismantle stud bolt 6, take off gland 7; Special-purpose extractor is rather gone in the top tapped blind hole C of briquetting 8, briquetting 8 is taken out, take out spring 4, spool 3, lining 2 successively; Inspection, the parts that change to damage are ressembled and are got final product.
