Abstract
Technical problem to be solved in the utility model is：A kind of butterfly valve of utilization y shapes adjustable elastic valve seat construction is provided, to solve technological requirement height, the defect that sealing and torque can not be adjusted in the prior art.Including disc, inlet connection mouth, valve body, execution structure, discharge connection mouth, also include y shape elastic seats, the fixed part of the y shapes elastic seat is arranged between inlet connection mouth and valve body, and the free elastic part of y shape elastic seats is contacted and sealed with disc.Y shape elastic seats have preferable processing technology, common lathe can complete processing, the crush of y shapes elastic seat and disc is can adjust by adjusting the thickness of valve seat adjusting pad, so as to adjust the sealing and required rotating torque of y shapes elastic seat and disc sealing pair.
Description
Technical field
The utility model is related to a kind of butterfly valve, more particularly to a kind of butterfly valve of utilization y shapes adjustable elastic valve seat construction.
Background technology
Current butterfly valve seat structure generally has following several：Z-shaped valve seat, hook-shaped valve seat, C-shaped valve seat and U-shaped valve seat, on
State valve seat construction and be respectively provided with preferable elasticity, but high is required to processing technology, size and Geometrical Tolerance Principle are high, assemble simultaneously
After the completion of sealing and torque can not be adjusted, it is difficult to meet seal request and the requirement of disc driving moment simultaneously.
The content of the invention
Technical problem to be solved in the utility model is：A kind of butterfly valve of utilization y shapes adjustable elastic valve seat construction is provided,
To solve technological requirement height, the defect that sealing and torque can not be adjusted in the prior art.
In order to solve the above technical problems, the technical scheme that the utility model is used is：
A kind of butterfly valve of utilization y shapes adjustable elastic valve seat construction, including disc, inlet connection mouth, valve body, perform structure,
Discharge connection mouth, it is characterized in that：Also include y shape elastic seats, the fixed part of the y shapes elastic seat be arranged on into
Between mouth pressure inlet and valve body, the free elastic part of y shape elastic seats is contacted and sealed with disc.
Further, it is provided with valve seat adjusting pad between the y shapes elastic seat and valve body.
Further, the y shapes elastic seat is polytetrafluoroethylmaterial material.
Further, it is provided with pressure inlet adjusting pad between the y shapes elastic seat and inlet connection mouth.
Further, the y shapes elastic seat is elastic metallic material.
The beneficial effects of the utility model are：Y shape elastic seats have preferable processing technology, common lathe
Processing is completed, the crush of y shapes elastic seat and disc is can adjust by adjusting the thickness of valve seat adjusting pad, so as to adjust y shapes
The sealing and required rotating torque of elastic seat and disc sealing pair.
Brief description of the drawings
Fig. 1 is embodiment butterfly valve structure sectional view；
Fig. 2 is y shape elastic seat partial enlarged drawings in Fig. 1.
In figure, 1- discs, 2- inlet connections mouth, 3- rubber o-rings, 4- pressure inlets adjusting pad, 5- valve seats adjusting pad, 6-y
Shape elastic seat, 7- valve bodies, 8- perform structure, 9- axles, 10- discharge connections mouth, 11- plugs, 12- keys.
Embodiment
The utility model is described in detail with reference to specific embodiments and the drawings.
As Figure 1-Figure 2, embodiment provides a kind of butterfly valve of DN180 latus rectums applied to certain air pipeline, using y shapes
Product weight 2.5kg after adjustable elastic valve seat construction, disc operational torque about 1-1.3N*m, maximum leak rate about 12L/min, by dish
Disk 1, inlet connection mouth 2, rubber o-ring 3, valve seat adjusting pad 5, valve body 7, execution structure 8, axle 9, discharge connection mouth 10, plug
11st, key 12 etc. is constituted.Embodiment also includes y shapes elastic seat 6, and the fixed part of y shapes elastic seat 6 is arranged on inlet connection mouth
Between 2 and valve body 7, the free elastic part of y shapes elastic seat 6 is contacted and sealed with disc 1.Y shapes elastic seat 6 connects with entrance
Pressure inlet adjusting pad 4 is provided between ozzle 2.
Y shapes elastic seat 6 is added by polytetrafluoroethylmaterial material machine to be formed, and can also be added with the elastic metallic material machine of progress, y shapes
The sealing surface of elastic seat 6 is stretches out the free elastic part of valve seat body, with the formation sealing pair of disc 1.First pre-installed during assembling
One valve seat adjusting pad 5, the decrement to y shapes elastic seat 6 and disc 1 is measured, it is ensured that suitable decrement, works as compression
Amount can be adjusted when being unsatisfactory for requiring to the thickness of valve seat adjusting pad 5.Filled after the completion of the decrement adjustment of y shapes elastic seat 6
Ozzle adjusting pad 4 is coupled, it is ensured that inlet connection mouth 2 can normally compress y shapes elastic seat 6 and be unlikely to conquassation y shape feather valves
Seat 6.If y shapes elastic seat 6 is elastic metallic material, can be without pressure inlet adjusting pad 4.
