Detailed description of the invention
Fig. 1 is the structural schematic diagram of valve body;
Fig. 2 is the cross-sectional view of gasket;
In figure: flange, half valve body of 3-, 4- gasket, 5- anchor ear, 6- positioning plate in 1- end flanges, 2-.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing, to the present invention into
Row is further described.
As shown in Figure 1, 2, detachable valve body blow valve disclosed by the invention, including valve body, valve body are used for into and out of end
The end flanges 1 connecting with pipeline, body top have middle flange 2, and valve body is made of the two symmetrical docking of half valve body 3 fixations, and two
Gasket 4, the contact surface shape adaptation of the shape of gasket 4 and two and half valve bodies 3, it is preferable that close are equipped between a half valve body 3
The thickness of packing 4 is no more than 1mm.Two and half valve bodies 3 are solid by the anchor ear 5 at the anchor ear 5 and middle flange 2 at two end flanges 1
It is fixed.
Body base be easy to cause bottom that cannot seal due to not having fastening force.With this present embodiment, in valve body
Bottom welding location-plate 6, since valve body shape is arc, fixed plate 7 uses wire cutting in production, is guaranteeing angle
In the case of, make positioning plate 6 preferably close to valve body surface.Positioning plate 6 arranged at the bottom of two and half valve bodies 3, on two and half valve bodies 3
6 thread connection of positioning plate, tried hard to keep by bolt of fixing plate demonstrate,prove body base sealing.
The manufacturing method of detachable valve body blow valve disclosed by the invention, comprising the following steps:
Step 1, monoblock cast valve body;
Step 2, use wire cutting by the symmetrical sectility of valve body for two halves;
Step 3, the cutting plane of two and half valve bodies 3 is ground;
Step 4, two and half valve bodies 3 are assembled, comprising the following steps:
Step 4.1, one of them half valve body 3 keeps cutting to place up, places on the cutting plane upward close
Another half valve body 3 is fastened on 4 top of gasket by packing 4;
Step 4.2, upper anchor ear 5 is bound round at end flanges 1, and upper anchor ear 5 is bound round at middle flange 2.
When carrying out wire cutting, due to casting the defects of having stomata, wire cutting is easy to produce electric current during wire
Unstable, cutting surface roughness is not able to satisfy seal request.And conventional surface numerical control grinding, stock removal are too big, after grinding
Gap is too big between cutting valve body, therefore therefore in step 3, and first double of valve body 3 carries out grinding positioning, rear to be controlled by amesdial
Amount of grinding.
Step 3 specifically includes the following steps:
Step 3.1, half valve body, 3 clamping is fixed on grinding machine, the cutting of half valve body 3 is face-up, and thousand points are used when clamping
Table carries out cutting plane relatively flat, it is ensured that cutting plane is parallel to the horizontal plane;
Step 3.2, numerically control grinder is opened, starts to grind;In grinding, pause amesdial measures amount of grinding.The present invention is not
It only can guarantee lapped face flatness, and valve body cutting plane amount of grinding is very small, ensure that the gap value between after valve body is assembled
It is small, it ensure that flange is round enough after assembly.
In assembly, two and half valve bodies 3 are difficult to position, and slightly dislocation will result in leakage, thus cutting on line valve body it
Preceding just to weld two positioning plates 6 in body base, two positioning plates 6 are symmetrical arranged about the cutting plane of valve body, set on positioning plate 6
There is connecting hole.Body base has first welded positioning plate 6, then carries out wire cutting again, can pass through positioning in assembly in this way
Plate 6 positions two and half valve bodies 3, guarantees to misplace when valve body assembly.In step 4.2, with bolt two positioning plates 6
It tenses.
Wherein, before step 4, gasket 4 is first manufactured, gasket 4 is sealed for valve body cutting plane, too due to cutting plane
Greatly, sealing difficulty is higher;Section shape complex contour simultaneously, has arc, there is cross etc., therefore, close in present embodiment
Packing 4 is prepared by the following method, comprising the following steps:
The first step, first the cutting plane of double of valve body 3 is scanned;
The figure of scanning is imported numerical control cutting machine by second step, and Numerical control cutting obtains gasket 4.
The gasket 4 that this method obtains, can completely be fitted on cutting surface after assembly.The present invention is by sealing
Surface increases gasket 4, by calculating pretightning force in detail, while guaranteeing sealing, flange will not be made to become ellipse.
After two and half valve bodies 3 are assembled, it is also necessary to be sealed detection, since valve body surface is uneven, assemble
When carrying out sealing detection after well, the place leaked occur may be different, at this point, sealing can be made to let out by the direction of rotation anchor ear 5
The bolt power of leak increases, to realize sealing.
In use, if inner body needs to change, by dismantling hooping structure, i.e., replaceable inner body,
Without entirely disassembling valve, maintenance valve times and cost is greatly saved.
Due to washing away for a long time for fluid, the loss of valve body wall thickness and the variation of valve inner flow channel shape will cause, this
The method of a kind of valve body wall thickness for monitoring detachable valve body blow valve of disclosure of the invention and flow channel shape situation of change, it includes following
Step:
Step 1, valve body is dismantled;
Step 2, two and half valve bodies 2 are scanned, obtain data.
The present invention is convenient under actual condition, can dismantle valve body at any time, and observation valve body washes away situation, assesses under the operating condition
Situation is washed away in the real work of other valves;Meanwhile very big convenience is also provided for fluid test, it is conducive to carrying out fluid
When test, the more intuitive test situation for observing the structure, to acquire wall thickness data etc. when subsequent progress washout test.
Certainly, the present invention can also have other numerous embodiments, without deviating from the spirit and substance of the present invention,
Those skilled in the art can make various corresponding changes and modifications, but these corresponding changes and change according to the present invention
Shape all should fall within the scope of protection of the appended claims of the present invention.
