Description
Technical field
The invention belongs to graphite pressing pressure container manufacture field, and in particular to a kind of graphite valve with metal enhancing.
Background technology
Graphite is a kind of crystalline carbon, its chemical property torpescence, corrosion-resistant, is not reacted with acid, alkali etc..Because it has
The features such as two-dimensional structure and lubrication, high temperature resistant, stable chemical performance, long usage time, it is set to be processed to graphite valve and wide
It is general to be applied to oil, chemical industry, nuclear power industry.Graphite valve decay resistance is strong, and usage time length, maintenance cost is low, uses
The devices such as graphite valve, pump and pipeline, it will not be reacted when class I liquid I is corroded in conveying.At present, graphite lining valve is adding
In work, one layer of acid resistant adhesive mortar, then lining stone ink, or the side mechanically connected with graphite are mainly first served as a contrast inside device to be processed
Method, processing method is more complicated, does not apply to the processing of small parts.And the degree of adhesion of graphite lining and device inwall is not
Good, air-tightness also has much room for improvement, seriously corroded, and service life is shorter.
The content of the invention
The invention aims to solve in the prior art, graphite lining valve corrosion resistant performance is poor, and service life is short
Problem.And then provide a kind of manufacture method of graphite valve and its pump, valve and the pipeline of manufacture of metal enhancing.
The technical scheme is that：A kind of manufacture method of the graphite valve with metal enhancing, including valve rod 1, ball
Strengthen metal shell 4 outside body door 2, graphite valve body 3 and valve, the outer wall and fluid passage of spheroid door 2 are graphite, spheroid door 2 by
Power part by graphite spheroids the method for casting metals manufactured, to whole spheroid door 2 again pass through be machined complete
The manufacture of spheroid door 2.Being manufactured into by the use of graphite valve body 3 as inner membrance by outer membrane metal outside valve strengthens metal shell 4, by stone
Black valve body 3 forms whole valve body with strengthening metal shell 4 outside valve.
The present invention has the advantages that：The manufacture method of the present invention and prior art contrast, employ reverse
Thinking.Its first processing graphite valve body and spheroid door, reprocess the thinking of valve housing so that processing technology greatly simplifies, especially
It is adapted to the processing of the large, medium and small type of manufacture and complex part, makes it have more preferable air-tightness, heavy antisepsis, durability.
Brief description of the drawings
Fig. 1 is the structural representation of metal enhancing graphite valve of the present invention.
The present invention includes valve rod 1, spheroid door 2, graphite valve body 3, valve strengthens metal shell 4 outside.
Embodiment
With reference to specific embodiment, the present invention will be further described：
Referring to Fig. 1, a kind of graphite valve with metal enhancing of the present invention, including valve rod 1, spheroid door 2, graphite valve
Strengthen metal shell 4 outside body 3 and valve, the outer wall and fluid passage of spheroid door 2 are graphite, the part of the force of spheroid door 2 by
The method of casting metals is manufactured in graphite spheroids, completes the system of spheroid door 2 by being machined again to whole spheroid door 2
Make.Being manufactured into by the use of graphite valve body 3 as inner membrance by outer membrane metal outside valve strengthens metal shell 4, by graphite valve body 3 and valve outside
Enhancing metal shell 4 forms whole valve body.
The method for manufacturing above-mentioned valve body and spheroid door, comprises the following steps：
A lining) is prepared：Graphite powder is taken, glue mixing extruding is passed it through and after mould pressing process, high temperature is baked into and the ball
Strengthen metal shell 4 outside the valve that the interior exocoel geomery of body door 2 and graphite valve body 3 matches；
B mould and metal shell) are prepared：Internal model using the graphite valve body 3 in above-mentioned steps as mould, recycle sand mo(u)ld
External mold casting metals liquid cast as mould, which goes out, strengthens metal shell 4 outside valve；
C spheroid and valve body) are prepared：The valve body and spheroid that will be cast after hot melt, and being cooled and shaped, remove mould external mold it
Afterwards, that is, the graphite valve that there is metal to strengthen is obtained.
The sand casting that the present invention applies is widely used cast form.Just as the name indicates, exactly manufactured with sand
Mold.Sand mo(u)ld processing factory can be with casting large-scale part, and its is cheap, and can produce the part of various sizes, and equipment is thrown
Money is few, and raw material are easy to get and cheap.
And the dexterously internal model using graphite valve body as mould of the invention, it is used in combination with sand mo(u)ld so that graphite valve body
It is combined together with the metal in close after hot melt, heavy antisepsis and air-tightness are very good.
To sum up, manufacture method of the invention and prior art contrast, employ reverse thinking.Its first processing graphite valve
Body and spheroid door, reprocess the thinking of valve housing so that processing technology greatly simplifies, be especially suitable for the large, medium and small type of manufacture and
The processing of complex part, make it have more preferable air-tightness, heavy antisepsis, durability.
The invention is not restricted to prepare valve, in addition in batch, largely produce the graphite valve of the enhancings such as aluminium alloy, copper alloy
Door.
The above is only presently preferred embodiments of the present invention, is not intended to limit embodiment of the present invention, and this area is general
Lead to central scope and spirit of the technical staff according to the present invention, can very easily carry out corresponding flexible or modification, therefore originally
The protection domain of invention should be defined by the protection domain required by claims.
