Valve, has additional the vacuum layer of heat-insulation and heat-preservation on the cylinder of Pneumatic gate valve, the outside of vacuum layer is provided with asbestos layer, outside asbestos layer
Portion sets metal shell.
By above-mentioned technical proposal, vacuum layer keeps apart outside heat, prevents the incoming pneumatic flashboard of excessive heat
On the cylinder of valve, the setting of asbestos layer reduce further the transmission of heat, and serve reduces cylinder environment temperature well
On the one hand effect, metal shell can play heat-insulated effect, on the other hand strengthen the steadiness of Pneumatic gate valve cylinder, prevent
Cylinder is beaten and is ruptured by external force etc. and influenceed equipment normal operation.
Further it is optimized for：Vacuum melting furnace with Pneumatic gate valve protection device, outside described asbestos layer and metal
One end that shell adjoins Pneumatic gate valve is respectively equipped with the first snap finger and the second snap finger, and asbestos layer is fastened on described by the first snap finger
Vacuum layer outside, metal shell is fastened on the outside of asbestos layer by the second snap finger.
By above-mentioned technical proposal：Asbestos layer and metal shell form the snap finger of back-off in close Pneumatic gate valve one end,
By the deformability squeeze buckle dog clutch of itself outside vacuum layer, metal shell is squeezed asbestos layer also by the deformability of itself
Clinching pawl is fastened on outside asbestos layer, i.e., be both connected to outside the cylinder of Pneumatic gate valve by the deformation of itself, a side
Face causes that vacuum layer is mutually independent with asbestos layer and metal shell, it is ensured that the independence of vacuum layer so that heat-insulated effect
More preferably, the engaging of another aspect snap finger is also convenient for dismounting to fruit.
Further it is optimized for：Vacuum melting furnace with Pneumatic gate valve protection device, described metal shell is aluminium conjunction
Gold shell processed.
By above-mentioned technical proposal, metal shell is set to aluminium alloy shell, while fixing asbestos layer, alleviated
The gravity of itself, decreases the heavy burden to cylinder while heat-insulated.
Further it is optimized for：Vacuum melting furnace with Pneumatic gate valve protection device, vacuum melting body of heater top is set
Upper lid, upper tops connect main feed compartment.
The upper lid set by above-mentioned technical proposal, smelting furnace top so that the refining material in the main feed compartment at top can be very
Good falling into carry out melting, optimization production in crucible.
Further it is optimized for：Vacuum melting furnace with Pneumatic gate valve protection device, vacuum melting furnace interior is set
Crucible, crucible inside is graphite core.
By above-mentioned technical proposal, graphite core is used for carrying out high temperature drying to crucible, it is ensured that the cleaning of crucible, so as to melting
Raw material.
The utility model advantage compared with prior art is：By setting up vacuum on the cylinder of Pneumatic gate valve
Layer, the outside of vacuum layer sets asbestos layer, and the outside of asbestos layer sets metal shell, effectively heat is isolated from outside cylinder,
The damage that hot environment is brought to the cylinder of Pneumatic gate valve is avoided, the service life of cylinder and pneumatic element is extended, protected
The normal operation of production is demonstrate,proved.
