Description
Technical field
The utility model belongs to valve field, and in particular to be a kind of double-shaft two-way means of press seals welding butterfly valve.
Background technology
Valve is the control unit in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the functions such as overflow pressure relief, it is used for the valve of fluid control systems, from simplest shut-off valve to extremely complex robot control system(RCS)
Used in various valves, kind and specification are quite various, valve can be used for controlling empty gas and water, steam, various corrosivity be situated between
The flowing of the various types fluid such as matter, mud, oil product, liquid metal and radiating medium.Valve is also divided into cast iron according to material
Valve, cast steel valve, stainless valve (201,304,316 etc.), chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, modeling
Expect valve, nonstandard customized valve etc., but existing valve is susceptible to loosening and damage, stress in the case where hydraulic pressure is larger
Intensity is poor, and service life is relatively low, poor so as to cause sealing effect.
Utility model content
In order to solve the above technical problems, the utility model provide it is a kind of can increase stress intensity, increase leakproofness
Double-shaft two-way means of press seals welds butterfly valve.
To achieve the above object, the technical solution adopted in the utility model is a kind of double-shaft two-way means of press seals welding butterfly valve,
Bearing including valve body and across valve body setting, bearing are equipped with valve plate, and structural feature is that bearing includes upper semiaxis and lower half
Axis, the valve body are equipped with upper opening and under shed, and upper bearing fixing sleeve is respectively equipped in upper opening and under shed under
Portion's bearing fixing sleeve, upper semiaxis are located in upper bearing fixing sleeve, and lower semiaxis is located in lower bearing fixing sleeve, and upper semiaxis is under
Semiaxis is connected by twin shaft fixing sleeve, and the both ends of the valve body are connected with valve seat.
It is connected under shed as a further improvement of the utility model, for lower bearing to be sealed in valve inner
Bottom cover.
The top of valve body is equipped with the dynamic turbine head and control of control upper half shaft rotation as a further improvement of the utility model,
The handwheel of turbine head rotation.
Airtight and watertight padding is equipped between upper bearing fixing sleeve and valve body as a further improvement of the utility model,.
The utility model has the beneficial effects that：Reasonable design, it is simple in structure, stress intensity can be increased, increase leakproofness,
Increase service life, and can sealing performance reach best, realize it is two-sided zero leakage.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Wherein, 1- valve bodies, 2- valve plates, the upper semiaxis of 3-, semiaxis under 4-, 5- upper bearing fixing sleeves, 6- lower bearings are fixed
Set, 7- twin shaft fixing sleeves, 8- bottom covers, 9- turbine heads, 10- handwheels, 11- airtight and watertight paddings.
Specific implementation mode
Explanation is further explained to the utility model with reference to the accompanying drawings and detailed description, but does not limit this reality
With novel protection domain.
As shown in Figure 1, a kind of double-shaft two-way means of press seals welds butterfly valve, including valve body 1 and the bearing across the setting of valve body 1,
Bearing is equipped with valve plate 2, and the bearing includes upper semiaxis 3 and lower semiaxis 4, the valve body 1 be equipped with upper opening and under open
Mouthful, it is respectively equipped with upper bearing fixing sleeve 5 and lower bearing fixing sleeve 6 in upper opening and under shed, upper semiaxis 3 is located at upper axis
It holding in fixing sleeve 5, lower semiaxis 4 is located in lower bearing fixing sleeve, and upper semiaxis 3 and lower semiaxis 4 are connected by twin shaft fixing sleeve 7,
The both ends of the valve body 1 are connected with valve seat；It is connected on the under shed for lower semiaxis 4 to be sealed in valve body 1
Internal bottom cover 8；The top of the valve body 1 is equipped with what the turbine head 9 that the upper semiaxis 3 of control rotates was rotated with control turbine head 9
Handwheel 10；Airtight and watertight padding 11 is equipped between the upper bearing fixing sleeve and valve body.
Valve seat in the utility model is generated by the effect of pipeline medium to be moved between valve body 1 and pipeline, thus by valve
Body 1 is fixed, and so that its sealing effect is reached best, is made its two-sided zero leakage, and the utility model is connected using twin shaft, is avoided
When pressure is excessive, bending shaft is generated when torsion is excessive.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing in the equivalent requirements of the claims will be fallen
All changes in justice and range are embraced therein, and should not any reference numeral in claim be considered as limitation
Involved claim.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiment being appreciated that.
