Abstract
The utility model provides a half flexible hinged joint formula exhaust and brake butterfly valve, includes valve body component, and valve body component is connected with the bracket component, and the valve block is connected with rockshaft assembly, and cylinder components articulates on the support of bracket component, and cylinder components includes the cylinder body, and the cylinder body has outside overhang, and the overhang is opened porosely, and the back shaft is located it is downthehole, for supporting cover I between hole and the back shaft, support and be equipped with damping rubber ring between cover I and the back shaft. This is novel to constitute half flexible hinged joint through supporting the cover with damping rubber ring, but exhaust brake in -process automatically regulated position, and the impact nature that reduces between cylinder components and the rockshaft assembly is worn and torn firmly, improves the life who brakies the butterfly valve.
Description
Technical field
The utility model is related to engine exhaust and brake technical field, more particularly, to a kind of cylinder and supporting plate semi-flexible
Hinged exhaust brake butterfly valve.
Background technology
As the vitals of engine exhaust auxiliary braking --- exhaust brake butterfly valve, the company between its cylinder and support
Two kinds are connected in, to be rigidly connected, i.e., by a metallic sheath that cylinder assembly and the bracket component back of the body is tight, another kind is flexibility to one kind
Connection, i.e., it is by rubber sleeve that cylinder assembly and the bracket component back of the body is tight.The advantage that is wherein rigidly connected is the center of cylinder assembly
Height is good with the centre-height uniformity of rocking arm shaft assembly, working condition lower cylinder component will be caused if there is deviation and is shaken
The concentrated wear of arm axle component is serious, and ultimately causes exhaust brake defective valve, although to solve concentrated wear tight for flexible connection
The problem of weight, but entirely exhaust brake valve transmission accuracy is low, exhaust back pressure is unstable.
The content of the invention
The purpose of this utility model is to overcome shortcoming present in prior art, there is provided a kind of semi-flexible interconnection system exhaust
Braking butterfly valve, the braking butterfly valve solves disadvantage present in prior art, the technical side of employing by semi-flexible connected mode
Case is：A kind of semi-flexible hinge jointing type exhaust brake butterfly valve, including valve component, the valve component connects with bracket component
Connect, valve block is connected with rocking arm shaft assembly, cylinder assembly is hinged on the support of the bracket component, it is characterised in that：The gas
Cylinder component includes cylinder body, and the cylinder body has outside jag, and the jag is provided with hole, and support shaft is located in the hole,
It is support set I between the hole and support shaft, damping cushion rubber is housed between the support set I and support shaft.
Technical characteristic of the present utility model also has：The bottom of the support set I is support set II, the support set II and institute
State and be also equipped between hole damping cushion rubber.
Technical characteristic of the present utility model also has：It is sealing ring between the bottom of the support set II and the support, institute
State the built-in support shaft in hole of sealing ring.
Technical characteristic of the present utility model also has：The support shaft is threaded away from one end of the support, nut
The back of the body is tightly in the top of the support set I.
The beneficial effects of the utility model are：Originally it is new that semi-flexible hinge company is constituted by support set and damping cushion rubber
Connect, during exhaust brake can automatic position adjusting function, the impact hard grind reduced between cylinder assembly and rocking arm shaft assembly damages, carries
The service life of height braking butterfly valve.
Description of the drawings
Accompanying drawing 1 is the utility model front view, and accompanying drawing 2 is the partial enlarged drawing of accompanying drawing, and 1 is packing ring, and 2 is nut, and 3 is gas
Cylinder component, 4 is rocking arm shaft assembly, and 5 is bracket component, and 6 is valve component, and 7 is valve block, and 8 is support set I, and 9 is damping cushion rubber,
10 is support set II, and 11 is support shaft, and 12 is sealing ring.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.The utility model discloses a kind of
Semi-flexible hinge jointing type exhaust brake butterfly valve, the braking butterfly valve includes valve component 6, and valve component 6 connects with bracket component 5
Connect, valve block 7 is connected with rocking arm shaft assembly 4, cylinder assembly 3 is hinged on the support of bracket component 5.
Cylinder assembly 3 includes cylinder body, and cylinder body has outside jag, and jag is provided with hole, and support shaft 11 is located in hole,
It is support set I 8 between hole and support shaft 11, damping cushion rubber 9 is housed between support set I 8 and support shaft 11.The bottom of support set I 8
For support set II 10, damping cushion rubber is also equipped between support set II 10 and hole.It is close between the bottom of support set II 10 and support
Seal 12, the built-in support shaft 11 in hole of sealing ring 12.Support shaft 11 is threaded away from one end of support, and nut 2 is carried on the back and tightly existed
The top of support set I 8.
Certainly, described above is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
Change, remodeling, addition or replacement that the those of ordinary skill in art field is made in essential scope of the present utility model, also belong to
In protection domain of the present utility model.
