Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
The elastic packing valve seat construction of this fixing ball valve, including valve seat 1, O 2, elastic support 3, support ring 4, filler 5, valve body 6 and valve ball 7；Interior step is offered in the valve body 6 of close valve ball 7 side, the runner of interior step and valve body 6 is in being coaxially disposed, elastic support 3, support ring 4, filler 5 and valve seat 1 it is provided with in this interior step, one end of elastic support 3 offsets with the bottom surface of interior step, the other end of elastic support 3 offsets with support ring 4, the other end of support ring 4 offsets with filler 5, filler 5 offsets with valve seat 1, valve seat 1 towards valve ball 7 side offers spherical groove, being embedded with described O 2 at spherical groove, O 2 contacts with described valve ball 7.
Described O 2 is metal material, and O 2 is hollow-core construction.
Described filler 5 has internal conical surface towards one end of valve seat 1, and valve seat 1 has outer conical surface towards one end of filler 5, and valve seat 1 is contacted by the inside and outside circle conical surface that tapering is equal with filler 5.
Described elastic support 3 is disk spring.
In this utility model, support ring 4 is arranged between filler 5 and elastic support 3, and the elastic compensating power provided by elastic support 3 is converted into face contact by linear contact lay.Described elastic support 3 is arranged between support ring 4 and valve body 6.
As shown in Figure 4, the spherical groove mouth outside described valve seat 1 is provided with semicircle antelabium, the equal rounding of corner, it is simple to the importing of O 2.
As shown in Fig. 1 ~ Fig. 2, described O 2 uses swelling bag pressure technique and lip extrusion process to be inlaid in the spherical groove of valve seat 1.
In this utility model, described O 2 can select non-self-tightening type, inflated type or self-tightening type as required.Non-self-tightening type O 2 is a hollow closed circle, applies in general to mesolow operating mode；It is filled with noble gas in the closed-loop of inflated type O 2, applies in general to the operating mode of High Temperature High Pressure；Self-tightening type O 2 tube wall side is drilled with balance pipe, and during installation, balance pipe is towards source pressure direction, applies in general to mesohigh operating mode.
Operation principle of the present utility model is as follows:
When O 2 selects non-self-tightening type, it produces resilience force after being compressed, and medium produces active force to metal hollow O 2 side simultaneously so that it is opening, under the effect of the two power, O 2 is close to the sealing surface of valve ball 7, reaches sealing effectiveness；When O 2 selects inflated type, the pressure in its ring can raise along with the rising of medium temperature, and resilience force is also constantly increasing, and medium yet suffers from active force to its side simultaneously, contributes to the laminating of O 2 and valve ball 7 sealing surface, and sealing effectiveness is good；When O 2 selects self-tightening type, medium balance pipe on tube wall enters in ring, makes O 2 internal and external pressure balance, and in conjunction with himself resilience force and the medium active force to its side, sealing effectiveness is best.Additionally, sealing between valve seat 1 and valve body 6 is realized by compressible filler 5, filler 5 uses multi-disc stacked structure, filler 5 has internal conical surface towards one end of valve seat 1, and valve seat 1 has outer conical surface towards one end of filler 5, and valve seat 1 is contacted by the inside and outside circle conical surface that tapering is equal with filler 5, disk spring 3 can be acted on the elastic compensating power in support ring 4 and pressure medium, lateral decomposition, improves seal pressure so that seal stability and high efficiency.
