5. repeat step 2. ~ 4. completed to the forging of whole copper base；
6. the copper base forged is used -85 ~ -75 DEG C in 10min after the completion of forging, is incubated the ice-cold processing of 1.5h ~ 2h；Then
Using 300 DEG C ~ 330 DEG C, the time of 1.5min/mm ~ 1.8min/mm based on copper base diameter is incubated, intensive treatment is carried out, institute is obtained
Need forge piece；
7. the forge piece 6. step obtained is processed into first check-valve main body and second check-valve using machining mode
Support column.
A kind of method for manufacturing composite construction shell, comprises the following steps：
1. use tin bronze cast casing, profile thickness is the 3/5 of final thickness, die cavity in refine, and use shot-peening with
0.15A-0.22A shot peening strength spray hair outer surface, then in outer surface spraying ZS-1071 high temperature resistant inorganic adhesives；
2. the PEEK of preparation is heated to molten state, obtains subsurface fluid；
3. the tin bronze cast casing that 1. step obtains is put into the encapsulation subsurface fluid progress top layer encapsulation that 2. step obtains, obtained
Obtain stand-by composite shell；
4. stand-by composite shell, closing inner chamber are taken out after temperature is down to 420 DEG C, then is placed in protective atmosphere gas booster, if
Standby interior air pressure is promoted to 8MPa-10MPa, keeps 1.5h-2h, and composite shell blank is obtained after taking-up；
5. the composite shell blank outer surface that 4. conditioning step obtains, and obtain required composite construction shell.
Compared with prior art, the present invention has advantages below：In prior art frequently with stainless steel, cast iron, plastics,
Brass, zinc alloy material etc., the service life and reliability of big-and-middle-sized environmentally friendly water control equipment are just ignored from material, is mainly adopted
Safeguard that the mode for changing accessory carries out function holding with continuous, but deriving and develop, this height of original technology with the epoch
Frequency is safeguarded and the shortcoming of basic property can no longer meet longevity of the existing Medium or severe type industry section control water field to double check valve (DCV)
Life, high reliability request, tin bronze have anti-corrosion, wear-resisting, high tenacity, the comprehensive advantage of high elastic limit, very applicable to answer
For double check valve (DCV) field, but directly on the one hand waste larger using the stingy system of blank, not on the one hand can not play the material completely
Expect the performance boundary applied in double check valve (DCV) field, the mode that the present invention swages by using side turn circle hot extrusion makes to have in blank
The forging flow lines that taper rotation is inwardly tightened up, then has excellent long-term creep resistance by being used in the not high structure position of stress
Property and fatigue performance working of plastics mitigate weight, reduce cost, increase shock resistance, then by suitable mode improve copper mould
Adhesion, this is also not precedented in the prior art, and the part of swaging especially in forging process is provided with the present invention should
To the specific aim of the random rotary motion rule of current（High-end double check valve (DCV) in routine techniques is typically also obtained only with hot forging
Linear pattern streamline, has certain improvement to performance but without the specific aim of the reply random rotary motion rule of current）；Originally simultaneously
Invention breaks through forging temperature in routine techniques and is higher than materials theory AC3The theoretical set for the temperature that 100 DEG C ~ 150 DEG C of temperature value,
Find that precipitation-hardening stainless steel is different from other steel grades in long-term practice, higher than AC330 DEG C ~ 50 DEG C of temperature value（General material
The hardening heat of material）When there is suitable plasticity, and at this moment forged, streamline, which changes, to be become apparent and rule, and use
The form of hydraulic means extruding carries out the generation that deformation also contributes to control internal fissure（Existing conventional forging is general using impact
Formula, forge crack is also easy to produce to underheated copper base）, while hydraulic means extruding also makes what material discharged in plastic deformation
Temperature is more stable controllable, initial forging temperature is more stablized compared to general forging and accurate, has also accomplished fluently base for swaging below
Plinth；Blank is square during due to hot forging, easily clamps, when the tapered bore with ceramic frock main body contacts simultaneously rotary squeezing,
The rotational deformation of square seamed edge is much larger than the deformation of cylindrical blank so that the double check valve (DCV) streamline curvature finally obtained is bigger, incline
Rake angle is bigger, and the scouring capability for tackling random current is stronger；Surface that the present invention is used spray hair process combining high temperature resistant without
Machine adhesive, greatly strengthen the adhesion between metal and plastics, simultaneously because material property, shock resistance has also been lifted,
Again through the specific pressurized treatments of our company, make plastics essence finer and close, combined with adhesive and metallic matrix even closer.
