Abstract
The utility model provides a kind of airtight three eccentricity and firmly seals and entirely weld butterfly valve, adopt full welded structure, valve body is welded by left and right valve body, butterfly plate rotatingshaft through right valve barrel and with the center line relative eccentric of whole butterfly valve, the vertical plane relative eccentric of butterfly plate rotatingshaft and butterfly plate, metal o-ring in " U " type, and is welded on the centre at the two ends up and down of valve body joint place, left and right respectively; Butterfly plate is in right valve barrel, butterfly plate top, with metal o-ring below the place of being fitted and connected be conical sealing face, and the center line relative eccentric of conical sealing face center line and whole butterfly valve, structure is simple, easy to use, eccentric structure makes its adjusting function and sealability all fine, airtight full welded structure is adopted to make butterfly valve entirety more safely without maintaining, eliminate structural the leak leak source of metal o-ring on valve body that conventional bolt inlays " U " type, sealing is more reliable, ensure that the zero leakage of medium.
Description
Technical field
The utility model relates to mechanical engineering valve technology field, particularly relates to a kind of airtight three eccentricity and firmly seals and entirely weld butterfly valve.
Background technique
Valve is in fluid system, is used for controlling the device of the direction of fluid, pressure, flow.Valve is the device medium in pipe arrangement and equipment (liquid, gas, powder) being flowed or stops also controlling its flow.
Valve is controlling component in pipeline fluid transporting system, and it is used to change path section and media flow direction, has the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.The valve of ball valve to be a kind of open-shut device be spheroid, spheroid is driven by valve rod, and around the valve that the axis of valve rod rotates.
Along with the development of society, along with the develop rapidly of the industries such as Modern Large tool, oil, chemical industry, new energy, nuclear industry, the butterfly valve of existing market has various structures, and cost is higher, complex process.
Model utility content
For above-mentioned defect of the prior art and problem, the airtight three eccentricity that the object of the utility model embodiment is to provide a kind of better reliability firmly seals and entirely welds butterfly valve, thus increases work efficiency.
In order to achieve the above object, the utility model embodiment provides following technological scheme:
A kind of airtight three eccentricity firmly seals and entirely welds butterfly valve, adopt full welded structure, comprise butterfly plate rotatingshaft, valve body, butterfly plate, metal o-ring, it is characterized in that, valve body is welded by left and right valve body, and left valve barrel height and the width are all less than right valve barrel, butterfly plate rotatingshaft through right valve barrel and with the center line relative eccentric of whole butterfly valve, the vertical plane relative eccentric of butterfly plate rotatingshaft and butterfly plate, the top of butterfly plate rotatingshaft connects turbine and power assisting device by top key; Metal o-ring is in " U " type, and metal o-ring is welded on the centre at the two ends up and down of valve body joint place, left and right respectively; Butterfly plate is fixedly linked by middle key in right valve barrel, with butterfly plate rotatingshaft, butterfly plate top, with metal o-ring below the place of being fitted and connected be conical sealing face, and the center line relative eccentric of conical sealing face center line and whole butterfly valve.
Preferred as technique scheme, described butterfly plate rotatingshaft top peripheral is nested with automatic sliding sleeve.
Preferred as technique scheme, butterfly plate rotatingshaft top peripheral, automatically sliding sleeve overlap sealing by follower by filler, and are automatically provided with filler between sliding sleeve and follower.
The airtight three eccentricity of the one that the utility model embodiment provides firmly seals and entirely welds butterfly valve, compared with prior art, advantage of the present utility model is just: structure is simple, easy to use, eccentric structure makes its adjusting function and sealability all fine, adopts airtight full welded structure to make butterfly valve entirety more safely without maintaining, eliminates structural the leak leak source of metal o-ring on valve body that conventional bolt inlays " U " type, sealing is more reliable, ensure that the zero leakage of medium.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation that the airtight three eccentricity of the utility model embodiment seals full welding butterfly valve firmly.
Fig. 2 is the structure for amplifying schematic diagram that the airtight three eccentricity of the utility model embodiment seals the metal o-ring weld of full welding butterfly valve firmly.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, airtight three eccentricity firmly seals and entirely welds butterfly valve, adopt full welded structure, comprise butterfly plate rotatingshaft 1, valve body, butterfly plate 3, metal o-ring 4, valve body is welded by left and right valve body 21,22, left valve barrel 21 height and the width are all less than right valve barrel 22, butterfly plate rotatingshaft 1 through right valve barrel 22 and with the center line relative eccentric of whole butterfly valve, the vertical plane relative eccentric of butterfly plate rotatingshaft 1 and butterfly plate 3, the top of butterfly plate rotatingshaft 1 connects turbine and power assisting device 12 by top key 11; Metal o-ring 4 is in " U " type, and metal o-ring 4 is welded on the centre at the two ends up and down of left and right valve body 21,22 joint place respectively; Butterfly plate 3 is fixedly linked by middle key 13 in right valve barrel 22, with butterfly plate rotatingshaft 1, butterfly plate 3 top, with metal o-ring 4 below the place of being fitted and connected be conical sealing face 31, and the center line relative eccentric of conical sealing face 31 center line and whole butterfly valve, butterfly plate rotatingshaft 1 top peripheral is nested with automatic sliding sleeve 5, automatic sliding sleeve 5 overlaps 62 sealings by follower 61 by filler, and is automatically provided with filler 63 between sliding sleeve 5 and follower 61.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
