Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

Embodiment one

As shown in Figure 1, described pressurized machine heat-insulating protective device, comprises thermal shield assembly 1 and cushion block 3.As Fig. 2, on described thermal shield assembly 1, corresponding pressurized machine 6 is provided with installs immovable point I 9 with the position (this position represents more clearly in FIG) of tailpipe 5 connection, installing immovable point I 9 can be a tapped hole, install immovable point I 9 to arrange ringwise, concrete number is depending on the requirement of join strength.As Fig. 3, thermal shield assembly 1 is made up of three parts, and be thermal shield I 1.1, thermal shield II 1.2 and thermal shield III 1.3 respectively, this three part can be bolted and be fixed together, and forms thermal shield assembly 1.

The shape of thermal shield assembly 1 is determined according to the profile of pressurized machine 6, guarantee that it can by whole pressurized machine 6 and pressurized machine bleed valve, protect, wrap up, larger distance to be had between thermal shield assembly 1 and pressurized machine 6, as Fig. 2, thermal shield assembly 1 has a lot of mouth, it is all in order to the profile meeting pressurized machine 6 designs, pressurized machine 6 has the part needing to leak outside, and is just exposed by these mouths.As shown in Figure 1, thermal shield assembly 1 medium position (position of corresponding booster intermediate body) is also provided with a discharge transom window mouth 8, and venting window 8 can be the forms similar with venetian blind.As shown in Figure 2, thermal shield assembly 1 is also provided with installation immovable point II 10.Thermal shield assembly 1 forms for cast or plate stamping.

Using method of the present utility model is described below: by pressurized machine 6 and associated components thermal shield I 1.1, thermal shield II 1.2 and thermal shield III 1.3 3 portion envelops, and with bolt by this three partial fixing together, namely form thermal shield assembly 1.As shown in Figure 14 and Figure 15, the more excellent form of the one for cushion block 3, it is provided with two mounting points, and one of them mounting points is connected with the installation immovable point I 9 on thermal shield assembly 1, and another mounting points is connected with clip 4, and Placement is that bolt connects.Clip 4 tailpipe 5 and pressurized machine 6 is fixed together by bolt, so just thermal shield assembly 1 passed through cushion block 3, fixes together with bolt and clip 4.

As shown in Figure 1, cushion block 3 is that fully exposure is aerial, and therefore, exhaust conductance can pass through Air flow to the heat of cushion block 3, and then decreases the heat by conduction to thermal shield assembly 1.And after installation, between thermal shield assembly 1 and pressurized machine 6, having larger distance, air is the poor conductor of reasonable heat, so just avoids the heat by conduction between pressurized machine 6 and thermal shield assembly 1.The ambient air of turbine case heating, can by the discharge transom window mouth 8 arranged, be discharged to thermal shield outside, air after turbine case can be avoided like this to heat is to the heat transfer of booster intermediate body part and supercharger air compressor part, simultaneously, this venting window 8 can also ensure the balance of the inner and outer air pressure of thermal shield assembly 1, meets the needs that thermal shield assembly 1 protects the pressurized machine bleed valve working pressure of getting up.

The utility model had both met the requirement of ship rule to pressurized machine 6 surface temperature limit value, served protective action again to pressurized machine 6, ensure that and used dry turbo shell pressurized machine of the present utility model can replace water-cooled turbine case pressurized machine, meet the requirement of ship rule.And thermal shield assembly 1 also has a place to install immovable point II 10, as shown in Figure 2, by installing immovable point II 10, thermal shield assembly 1 and other parts being secured together, ensure that the mode of vibration of thermal shield assembly 1.

Fig. 4 to Fig. 8 is each view of thermal shield assembly 1, and it indicates the one preferably mode of execution of thermal shield assembly 1, and Fig. 9 to Figure 13 is each view of general assembly drawing, and it indicates one of the present utility model preferably usage mode.
