And second body form, first body and second body fastened by the fastener after be in cylindrical structural, every group
The fastener includes the hook being engaged and an extension spring, it is described buckle be fixed on the extension spring by rivet it is described
On muff.
Preferably, the heat-insulated body includes internal layer, intermediate layer and outer layer, the internal layer is stainless steel wire stratum reticulare, outside
Layer is rubberised layer.
Preferably, the material in the intermediate layer is glass fiber cotton or ceramic fiber cotton or high silica wool or polycrystalline fibre cotton.
Preferably, the resistance to 1200 degree of high temperature of wavefront surface.
Preferably, the intermediate layer is made up of layer of glass fiber cotton and one layer of high silica wool.
Preferably, the mesh number of the stainless steel wire stratum reticulare is 120 mesh.
Preferably, the sewing thread is made up of resistant to elevated temperatures steel wire and aramid line.
Preferably, the fastener and the rivet are made by resistant to elevated temperatures stainless steel material.
Above-mentioned technical proposal has the following advantages that or beneficial effect：In above-mentioned muff, the cooperation of hook and extension spring makes
With the operation of more convenient user.The design method of three layers of insulation construction, enhances heat insulation and preservation effect.In addition, the knot of three-stage
Structure design method so that whole muff is more bonded pipeline, cuts off the space of heat losses, and it is outer with pipe to add set internal layer surface
Effective contact area of wall, noise and vibrations are reduced, when avoiding engine operation caused by shell wall with set internal layer space
Resonance.In addition, outer layer uses silica gel cloth so that intermediate layer to be wrapped up, not only environmental protection but also prevent that intermediate layer and user's is direct
Contact, is user-friendly.

Embodiment
A kind of muff for engine of the invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of muff for engine, including：Heat-insulated body 1 and for fastening heat-insulated body 1
Some groups of fasteners.Wherein, heat-insulated body 1 is connected and composed by three parts, the first body 11 for being respectively sequentially connected, bending
The body 13 of body 12 and second.Wherein, the first body 11 and the second body 13 be by being in cylindrical structural after fastener buckle, and
Bending is covered by being in irregular after fastener buckle, but after the first body 11, the buckle of 12 and second body of bending body 13
A passage is internally formed, to wrap up flexible joint, bellows or package duct.It is worthy of note that because bending occurs in pipeline
Situations such as, so using bending body 12, it becomes possible to ensure that whole muff is set in the flexible joint, bellows or package duct
On, whole device flexibility is high, is applicable in a variety of actual states.In addition, the length of the first body 11, the second body 13 with
And shape of diameter, bending body 12 etc., it can be changed according to the actual demand of user, with user-friendly.
For further, as shown in Fig. 2 the heat-insulated body 1 is made up of three-decker, respectively internal layer 21, intermediate layer 22
And outer layer 23, wherein internal layer 21 is stainless steel wire stratum reticulare, and the mesh number of the stainless steel wire stratum reticulare is preferably 120 mesh.Intermediate layer
22 be glass fiber cotton, the resistance to 1200 degree of high temperature of the glass fiber cotton.Outer layer 23 is silica gel cloth, and the thickness of the silica gel cloth is preferably 0.4cm.
For further, the material in intermediate layer 22 can also be ceramic fiber cotton or high silica wool or polycrystalline fibre cotton.This
Outside, the intermediate layer 22 can also be made up of layer of glass fiber cotton and one layer of high silica wool, or by one layer of ceramic fiber cotton and one
Layer glass fiber cotton is formed, or is made up of one layer of high silica wool and one layer of polycrystalline fibre cotton.By using two layers of different high temperature resistant
Intermediate layer 22 is made in heat-insulated material, can further improve the heat insulation effect in intermediate layer 22, and then improve whole muff
Heat insulating ability.In addition, the roughening for material used in intermediate layer 22, if user directly contacts glass fiber cotton or polycrystalline fibre cotton
Or ceramic fiber cotton etc., sense of touch are bad and not environmentally, so, intermediate layer 22 is carried out to one layer of parcel again with silica gel cloth, not only
Environmental protection and prevent the direct of intermediate layer 22 and user from contacting, be user-friendly.
For further, the sewing thread on the muff is made up of steel wire and aramid line, has resistant to elevated temperatures characteristic.
For further, as shown in figure 3, the fastener includes a hook 31 and an extension spring 32, the hook 31 and extension spring
32 are fixed on muff by rivet 33, and the extension spring 32 is engaged with hook 31, and muff is enclosed on into flexible joint, ripple
On line pipe or package duct.Wherein, fastener and rivet 33 are made by resistant to elevated temperatures stainless steel.Button is utilized compared to traditional
The operation with the use of more convenient user of the mode that sub-buckle is closed, hook 31 and extension spring 32, further, since the elastic force of extension spring 32 is made
With so that the applicable conduit types of the muff are wider.
In above-mentioned muff, the operation with the use of more convenient user of hook 31 and extension spring 32.Three layers of insulation construction
Design method, enhance heat insulation and preservation effect.In addition, the structure design mode of three-stage so that whole muff is more bonded
Pipeline, the space of heat losses is cut off, add effective contact area of the set surface of internal layer 21 and pipe outer wall, reduce noise and shake
It is dynamic, resonance when avoiding engine operation caused by shell wall with set internal layer 21 space.In addition, outer layer 23 use silica gel cloth with
Intermediate layer 22 is wrapped up, not only environmental protection but also prevents the direct of intermediate layer 22 and user from contacting, is user-friendly.
For a person skilled in the art, after reading described above, various changes and modifications undoubtedly will be evident.
Therefore, appended claims should regard whole variations and modifications of the true intention and scope that cover the present invention as.Weighing
Any and all scope and content of equal value, are all considered as still belonging to the intent and scope of the invention in the range of sharp claim.
