Description
Technical field
The present invention relates to a kind of tooling of valve body used in high water pressure test, in particular to a kind of interior with inner cavity
The valve body of inclined hole water outlet carries out the used closure tooling for blocking valve body intake-outlet when high water pressure test.
Background technique
For valve used in nuclear power field, after the completion of valve manufacture, high pressure water pressure is carried out to valve body
Degree test, to examine whether the intensity of valve body reaches design requirement；When test, all valve ports of valve body need to be sealed with plugging plate
It is stifled, high pressure water is then injected into the valve chamber of valve body, and pressure maintaining is for a period of time, see whether valve body has infiltration phenomenon；But work as
When body cavity has angling hole water outlet, since the compression tooling of body cavity inclined hole and plugging plate outer end is at certain angle
Degree, in high-potting, high pressure water is straight not at one to the outward pressure of plugging plate in the outside pressing force and valve chamber of plugging plate
It on line, is easy to make the plugging plate in valve port to be detached from valve body, causes to block test failure；In addition, inclining since plugging plate will be embedded into
In inclined hole water outlet, the side elevation of plugging plate be it is inclined columned, to reach the intracavitary medial surface with angling hole water outlet
O-ring seals will be arranged in the purpose fitted closely on the angled engagement surface, and existing O-ring seals are appropriate only for vertically
Cylinder facade, selection are suitble to the sealing ring on skewed cylinder pile facade to have difficulties.
Summary of the invention
The body strength test with inner cavity inclined hole water outlet that the present invention provides a kind of solves closure with tooling is blocked
The technical issues of selection of plate sealing ring is difficult and plugging plate is easily separated from valve body.
The present invention is to solve the above technical problem by the following technical programs:
A kind of body strength test closure tooling with inner cavity inclined hole water outlet, including valve body, are respectively set in valve body
There are valve body left end inclination water outlet, valve body right end inclination water outlet and valve body upper end water-exit vertically mouth, is tilted in valve body left end
Left plugging block is provided in the mouth of a river, being provided with left O shape between left plugging block and the inner cavity of valve body left end inclination water outlet seals
Circle is provided with right plugging block in valve body right end inclination water outlet, in the inner cavity of right plugging block and valve body right end inclination water outlet
Between be provided with right O-ring seals, water filling through-hole is provided in left plugging block, left pressure is provided on the left side of valve body
Plate is provided with right pressing plate on the right side of valve body, be respectively arranged between left pressing plate and right pressing plate upper split bolt and under
Split bolt is provided with central through hole in the center of left pressing plate, and water filling connection bend pipe, water filling connection are provided in central through hole
The right end of bend pipe and the left end of water filling through-hole are connected together by welding, pass through welding connection in the left end of water filling connection bend pipe
There is pressure inlet.
Valve body upper end capping is provided on the water-exit vertically mouth of valve body upper end, valve body upper end capping passes through connection bolt
It is fixedly connected with the valve body together, adjustable water pump is connected on pressure inlet.
Tooling of the present invention is simple, easy to use, saves production cost, shortens the delivery cycle of product.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawing:
A kind of body strength test closure tooling with inner cavity inclined hole water outlet, including valve body 11, in valve body 11 respectively
It is provided with valve body left end inclination water outlet 13, valve body right end inclination water outlet 14 and valve body upper end water-exit vertically mouth 15, in valve body
It is provided with left plugging block 3 in left end inclination water outlet 13, between left plugging block 3 and the inner cavity of valve body left end inclination water outlet 13
Left O-ring seals 4 are provided with, right plugging block 6 are provided in valve body right end inclination water outlet 14, in right plugging block 6 and valve body
Right O-ring seals 10 are provided between the inner cavity of right end inclination water outlet 14, water filling through-hole 17 is provided in left plugging block 3,
Be provided with left pressing plate 12 on the left side of valve body 11, right pressing plate 7 be provided on the right side of valve body 11, left pressing plate 12 with
It is respectively arranged with split bolt 8 and lower split bolt 9 between right pressing plate 7, the center of left pressing plate 12 is provided with central through hole
18, water filling connection bend pipe 2 is provided in central through hole 18, the right end of water filling connection bend pipe 2 and the left end of water filling through-hole 17 are logical
It crosses welding to be connected together, pressure inlet 1 is communicated with by welding in the left end of water filling connection bend pipe 2.
Valve body upper end capping 5 is provided on valve body upper end water-exit vertically mouth 15, valve body upper end capping 5 passes through connection
Bolt 16 is fixed together with valve body 11, and adjustable water pump is connected on pressure inlet 1；Present invention primarily contemplates how to set
Plugging plate is counted come the closure of inclination intake-outlet non-standard when solving the problems, such as the valve body water pressure test, facilitates the choosing of closure O-ring
It selects；Plugging plate is replaced with plugging block, plugging block is inserted into the inclination in water outlet, overcome in inclined valve body as plugging plate
The problem of cylindric side elevation selection sealing ring, cooperates the cylinder between water outlet in plugging block and inclined valve body, only
It need to select existing O-ring seals that good sealing effect can be realized；In addition, two side plates pass through the common pressure-bearing of plugging block again
The pressure of high pressure water in valve avoids plugging plate and is easy to be detached from the defect of valve body during the test.
