Abstract
A kind of shell class bearer pressure test equipment, including bottom plate, cover board, pressing plate, studs, pellet and plug；The bottom plate and pressing plate are arranged in parallel up and down, it is connected between the two by studs, therebetween by the press fitting of shell class bearer, pellet is loaded on the non-pressure area in shell class bearer inner cavity, at the lumen openings of bottom plate and cover plate for sealing shell class bearer, plug is in each screw hole of shell class bearer, the side hydraulic fluid port of pressing plate for sealing shell class bearer.This pressure test is equipped under the high pressure operating condition of 825bar, it is capable of detecting when whether each tested cast housing class bearer can effectively work, it is keeping in 30 minutes of high pressure, tested cast housing class bearer answers zero seepage, the case where pressure test table should decline without obvious pressure, if not meeting conditions above, there is leakage hidden danger in tested part, it can determine that as unqualified part, scrapped processing.
Description
Technical field
The utility model belongs to pressure test tooling, and in particular to the pressure test of shell class bearer is equipped.
Background technique
Large-scale cast housing class pressure part is in modern industry field using very extensive, such part is often in high temperature and pressure
Bad working environments under work, such as: the combustion gas exhausting waste gas valve chest of engine of boat and ship, the power hydraulic cylinder etc. of engineering machinery, institute
It is very harsh with the requirement of the pressure-bearing safety to such part, it is necessary to assure 100% is qualified, in order to guarantee the peace of bearer
Full property and reliability must carry out 100% pressure test to shell class pressure part.
In the prior art, it when testing shell class pressure part, is confined to test condition and test equipment is immature, lead to
Often pressure test can only be locally carried out to part pressure-bearing inner hole just to process after being completed pressure-bearing inner hole local pressure
The each oil duct communicated therewith, so pressing pervious pressure test mode, each pressure-bearing oil duct of the shell class bearer is real
It not being tested on border, such test result can not illustrate the pressure-bearing property of the shell class bearer completely, so
Also the case where it is qualified in test therefore usually to there is part, but is leaked after machined oil duct.That is, the prior art is not
Finished product after processing can be tested, objectively can not comprehensively reflect the pressure-bearing property of part, before occurring when test
The case where qualification, part leaks after processing oil duct.
Summary of the invention
The utility model in view of the deficienciess of the prior art, propose a kind of shell class bearer pressure test equipment,
User specially is being delivered before use, carrying out pressure 825bar(oil pressure or hydraulic pressure to shell class pressure part) safety test when use,
Each part of pressure test equipment is easy to install and remove, and entire pressure test sequence can be made safe, controllable.
The technical solution of the utility model is as follows:
A kind of shell class bearer pressure test equipment comprising bottom plate, cover board, pressing plate, studs, pellet and stifled
Head；The bottom plate and pressing plate are arranged in parallel up and down, are connected between the two by studs, shell class bearer is fitted in
Between the two, pellet is loaded on the non-pressure area in shell class bearer inner cavity, bottom plate and cover plate for sealing shell class bearer
Lumen openings at, plug is in each screw hole of shell class bearer, the side hydraulic fluid port of pressing plate for sealing shell class bearer.
This pressure test is equipped under the high pressure operating condition (oil pressure or hydraulic pressure) of 825bar, is capable of detecting when each tested
Whether cast housing class bearer can effectively work, and keep in 30 minutes of high pressure, tested cast housing class
The case where bearer answers zero seepage, and pressure test table should decline without obvious pressure, if not meeting conditions above, by
There is leakage hidden danger in the part of test, can determine that as unqualified part, scrapped processing.
This pressure test is equipped for finished product test, that is, after each oil duct of part processes completely, just to shell
Class pressure part carries out pressure test, and such test result objectively can comprehensively reflect the pressure-bearing property of part, prevented with
It is qualified when preceding test, after processing oil duct the case where part leakage.And this pressure test equipment each part be easily installed and
Disassembly, entire pressure test sequence be it is safe, it is controllable.
Detailed description of the invention
Fig. 1 is the usage state diagram of pressure test equipment.
In figure, 1, bottom plate, 2, cover board, 3, pressing plate, 4, big plug, 5, G1/8 plug, 6,1/4 plug of G1,7, double end spiral shell
Column, 8, bolt, 9, G1/2 plug, 10, O-ring seal, 11, nut, 12, shell class bearer.
Specific embodiment
The structure of the following is further explained with reference to the attached drawings the utility model:
Referring to Fig. 1, the present embodiment is the combustion gas exhausting waste gas valve that the shell class bearer 12 being directed to is engine of boat and ship
Shell, pressure test equipment include bottom plate 1, cover board 2, pressing plate 3, studs 7, pellet 4 and plug.Bottom plate 1 and about 3 pressing plate
Parallel arrangement is connected by studs 7 between the two, and therebetween by the press fitting of shell class bearer 12, pellet 4 is loaded on
Non-pressure area in the inner cavity of shell class bearer 12, the lumen openings of 2 seal casinghousing class bearer of bottom plate 1 and cover board
Place, bottom plate 1 and be provided with O-ring seal 10 on the sealing surface of shell class bearer, cover board by bolt 8 by being fixed to
At the lumen openings of shell class bearer.The screw hole that plug blocks up dress as needed is of different sizes, there are three types of, it is G1/8 stifled respectively
First 5,1/4 plug 6 of G1, G1/2 plug 9, in each screw hole of shell class bearer, 3 seal casinghousing class bearer of pressing plate
Side hydraulic fluid port.
In the present embodiment, the region equipped with pellet is non-pressure area, does not need charge of oil.In the boss outer circle on pellet top
There is sealing ring to be sealed the pressure-bearing inner hole of bearer, thus make the pressure-bearing inner hole of bearer and communicates therewith each
A oil duct forms the separate space being completely closed (region for having lines is marked in such as figure).
This pressure test equipment be in pressure 825bar(oil pressure or hydraulic pressure) safety test when to be used, pressure test fill
It is standby that the inner cavity of part to be tested is fully sealed by studs 7, nut 11 and cover board 2 by bottom plate 1, before mounting base,
It needs for pellet (4) to be installed in inner cavity of component in advance, then pressing plate 3 is mounted on to the side of part to be tested by bolt 8
Side hydraulic fluid port is fully sealed hydraulic fluid port, then respectively by the hexagonal spiro plug G1/8 plug 5 of belt glue pad, 1/4 plug 6 of G1 and G1/2
Plug 9 is installed at the corresponding screw hole of part to be tested, and all screw holes are fully sealed, and all parts confirm after the installation is completed,
Hydraulic oil slowly is injected to the confined area (marking the region for having lines in figure) of part to be tested inner cavity, at this time inner cavity of component
Pressure is gradually increased to test pressure 825bar, and entire boost process is continuous, part to be tested ne-leakage in boost process
Phenomenon stops pressurization after pressure rises to 825bar, is kept for pressure 30 minutes, entire pressure maintaining period, and all parts nothing is appointed
The phenomenon that leakage phenomenon, no any deformation or failure, after the test by pressure above test equipment, meet test result
Part just can be considered qualified.
