Abstract
The invention discloses a kind of steel-casting standard groove harmless inspecting methods, comprising the following steps: (1) in groove position, there are surpluses in roughing for steel-casting valve；(2) it is checked using ultrasonic probe from upper surface and side；(3) by state before steel-casting valve finished edge to welding；(4) magnetic powder or infiltration non-destructive testing are carried out in groove position.Above-mentioned technical proposal makes groove all in effective inspection area of ultrasonic examination there is no blind area is checked, is finish-machined to size requirement again after checking zero defect；Therefore missing inspection caused by ultrasonic examination blind area is avoided, it is ensured that check on the quality.
Description
Technical field
The present invention relates to valve technology fields, and in particular to a kind of steel-casting standard groove harmless inspecting method.
Background technique
Steel-casting standard groove generally requires very high, needs ultrasonic examination, magnetic particle inspection, penetration inspection during fabrication
The step of, because of existing standard groove wall thickness irregular structure, referring to Fig. 1 and Fig. 2, ultrasonic probe can not be completely attached to
To groove face, there are blind areas, and so as to cause missing inspection, high rejection rate, repair rate is high, causes working efficiency low, and manufacturing cost is high, real
It is poor with property.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide one kind to can be avoided because ultrasonic examination is blind
Missing inspection caused by area, it is ensured that check on the quality, to reduce the steel-casting standard groove harmless inspecting method of manufacturing cost.
To achieve the above object, the present invention provides the following technical scheme that a kind of lossless inspection of steel-casting standard groove
Checking method, comprising the following steps:
(1) in groove position, there are surpluses in roughing for steel-casting valve；
(2) it is checked using ultrasonic probe from upper surface and side；
(3) by state before steel-casting valve finished edge to welding；
(4) magnetic powder or infiltration non-destructive testing are carried out in groove position.
Make groove all in effective inspection of ultrasonic examination there is no blind area is checked by using above-mentioned technical proposal
In region, it is finish-machined to size requirement again after checking zero defect；Therefore missing inspection caused by ultrasonic examination blind area is avoided, it is ensured that
It checks on the quality.
Preferably, step (2), completely attaches to the inspection of steel-casting valve surface for ultrasonic probe.
Preferably, step (2), when ultrasonic probe is checked using one or more ultrasonic probes.
Preferably, step (3), excision groove position there are balance.
Preferably, step (4), carries out magnetic powder non-destructive testing in groove position.
Preferably, step (4), carries out infiltration non-destructive testing in groove position.
The invention has the advantages that compared with prior art, inspection method of the invention keeps groove complete there is no blind area is checked
Portion is finish-machined to size requirement after checking zero defect in effective inspection area of ultrasonic examination again；Therefore ultrasound is avoided
Wave checks missing inspection caused by blind area, it is ensured that checks on the quality.It is reprocessed after reducing groove welding, manufacturing cost is effectively reduced.
The invention will be further described with specific embodiment with reference to the accompanying drawings of the specification.
Detailed description of the invention
Fig. 1 is the schematic diagram that the prior art checks groove；
Fig. 2 is the enlarged diagram in the portion I in Fig. 1；
Fig. 3 is the schematic diagram that the embodiment of the present invention checks groove.
Specific embodiment
In the description of the present embodiment, it should be noted that such as occur term " center ", "upper", "lower", "left", "right",
"vertical", "horizontal", "inner", "outside", "front", "rear" etc., indicated by orientation or positional relationship be it is based on the figure
Orientation or positional relationship is merely for convenience of description of the present invention and simplification of the description, rather than the device of indication or suggestion meaning or
Element must have a particular orientation, be constructed and operated in a specific orientation, it is thus impossible to be interpreted as limitation of the present invention.
In addition, such as there is term " first ", " second ", " third " are used for description purposes only, be not understood to indicate or imply opposite
Importance.
Referring to Fig. 3, a kind of steel-casting standard groove harmless inspecting method disclosed by the invention, comprising the following steps:
(1) in groove position, there are surpluses in roughing for steel-casting valve；
(2) it is checked using ultrasonic probe from upper surface and side；
(3) by state before steel-casting valve finished edge to welding；
(4) magnetic powder or infiltration non-destructive testing are carried out in groove position.
Wherein, the purpose of step (4) is to avoid causing to leak due to the ultrasonic probe poor contact caused by irregular structure
Inspection；It is reprocessed after reducing groove welding, manufacturing cost is effectively reduced.
Preferably, step (2), completely attaches to the inspection of steel-casting valve surface for ultrasonic probe.
Preferably, step (2), when ultrasonic probe is checked using one or more ultrasonic probes.
Preferably, step (3), excision groove position there are balance.
Preferably, step (4), carries out magnetic powder non-destructive testing in groove position.
Preferably, step (4), carries out infiltration non-destructive testing in groove position.
Inspection method of the invention makes groove all in effective inspection area of ultrasonic examination there is no blind area is checked
It is interior, it is finish-machined to size requirement again after checking zero defect；Therefore missing inspection caused by ultrasonic examination blind area is avoided, it is ensured that check
Quality.It is reprocessed after reducing groove welding, manufacturing cost is effectively reduced.
Above-described embodiment is served only for that invention is further explained to specific descriptions of the invention, should not be understood as
Limiting the scope of the present invention, the technician of this field make the present invention according to the content of foregoing invention some non-
The modifications and adaptations of essence are fallen within the scope of protection of the present invention.
